Repetition Legislation. The Committee notes the Factories (Benzene) Regulations 1978 (as amended by S.I. No. 158 of 1993) and in particular notes the relevant provisions which give effect to Articles 2 (Use of substitute products), 6(1) and (2) (Measures taken to limit exposure of workers and Maximum levels of concentration) and 8 of the Convention (Adequate means of personal protection). With reference to its previous comments, the Committee encourages the Government to take into account current internationally agreed limit values for benzene as recommended by the American Conference of Industrial Hygienists, presently recommended at a maximum of 0.5 parts per million or 0.6 mg/m3. The Committee asks the Government to continue to provide information on any relevant legislative developments and to submit copies of such legislation once it has been adopted. Article 4(1). Prohibition of the use of benzene in certain work processes. The Committee once again reiterates its request that the Government adopt the required legislation to ensure that the use of benzene and products containing benzene are prohibited in certain work processes; and that this prohibition shall at least include the use of benzene and products containing benzene as a solvent or diluent, except where the process is carried out in an enclosed system or where there are other equally safe methods of work. The Committee asks the Government to keep it informed of any progress in this regard.Article 14(c) of the Convention and Part IV of the report form. Application of the Convention in practice and appropriate inspection services. The Committee requests the Government to provide general information on the manner in which the Convention is applied, including extracts of inspection reports and data on the number of workers covered by the Convention, if possible, disaggregated by gender and the number and nature of the infringements recorded.
The Committee notes that the Government’s report has not been received. It hopes that a report will be supplied for examination by the Committee at its next session and that it will contain full information on the matters raised in its previous direct request, which read as follows:
The Committee notes the information contained in the Government’s report, including partial responses to the Committee’s previous comments.
Article 2 of the Convention. Use of substitute products. The Committee notes that the Government refers to articles 7(1) and 7(2) of the Factories (Benzene) Regulations, according to which the National Occupational Safety and Health Information Centre (CIS) is required to offer advice on how to use harmless or less harmless substitute products instead of benzene or products containing benzene and the Department of Occupational Safety and Health Services is charged to transmit such information to employers. The Committee requests the Government to provide information in its next report on how effect is given to the requirement to ensure that available substitute products actually are used at workplaces instead of benzene or products containing benzene.
Article 4(1). Prohibition of the use of benzene in certain work processes. The Committee notes the Government’s statement that legislation prohibiting the use of benzene or products containing benzene in certain work processes has not yet been developed, but that work has been initiated to prepare such legislation. Given the long time that has passed since the Government ratified this Convention, the Committee expresses the firm hope that the Government in the very near future will adopt the required legislation giving effect to Article 4 of the Convention and asks the Government to transmit copies thereof once they have been adopted.
Article 6(1). Measures taken to limit exposure of workers to benzene. The Committee notes the Government’s statement that, according to Regulation 6 of the Factories (Benzene) Regulations, local exhaust ventilation is recommended on all possible escape routes during the process of manufacturing, handling and use of benzene and productions containing benzene. With reference to the terms of the Convention, the Committee notes that according to this Article all necessary measures shall be taken in this respect. The Committee requests the Government to take adequate measures, including considering a regulation of this issue in the context of the legislative reform referred to above (paragraph 3 above), to ensure that benzene vapours are removed from the working environment when the work processes cannot be carried out in an enclosed system, in accordance with this Article of the Convention.
Article 6(2). Maximum levels of concentration of benzene in the air at places of work. The Committee notes that, according to the Factories (Benzene) Regulations, the permitted concentration of benzene in the air of the places of work is 25 parts per million or 80 mg/m3, which corresponds to the limit referred to in Article 6(2) of the Convention. The Committee wishes, however, to draw the Government’s attention to the fact that, since the adoption of this Convention in 1971, scientific knowledge has evolved. According to up to date scientific knowledge reflected in, for example, the limits recommended by the American Conference of Industrial Hygienists (ACGIH) are notably lower, and are presently recommended to be at a maximum of 0.5 parts per million or 0.6 mg/m3. Against this background, the Committee requests the Government to provide further information on the maximum limit value applied in practice for occupational exposure to benzene.
Article 8. Personal protective equipment. The Committee notes that the report is silent as regards its previous comment on this issue and reiterates its request to the Government to provide information on how it is ensured that workers who, for special reasons, may be exposed to concentrations of benzene in the air of places of employment which exceed the prescribed maximum are protected against the risk of inhaling benzene vapour.
Article 10(1). Medical examinations. The Committee notes that, according to the Government, effect is given to Article 10(1) and (2) by paragraphs 2 and 3 of the Factories (Benzene) Regulations and that, in practice, the Occupational Health, Safety and Research Bureau is often called upon to carry out such examination as they have the competent personnel and laboratories. Against this background, the Committee requests the Government to provide further information on the number of medical examinations carried out and their periodicity.
Part IV of the report form. Application in practice. The Committee notes that the inspectors are responsible for the supervision of the application of the Convention and that the Department of Occupational Safety and Health Services has established an occupational hygiene unit to provide training to the inspectors in order for them to carry out their duties. The Committee requests the Government continue to provide information on labour inspections and in particular, information on the number of inspections carried out, the number and nature of infringements found and any actions taken as a result.
Article 4, paragraph 1. Prohibition of the use of benzene in certain work processes. The Committee notes the Government’s statement that legislation prohibiting the use of benzene or products containing benzene in certain work processes has not yet been developed, but that work has been initiated to prepare such legislation. Given the long time that has passed since the Government ratified this Convention, the Committee expresses the firm hope that the Government in the very near future will adopt the required legislation giving effect to Article 4 of the Convention and asks the Government to transmit copies thereof once they have been adopted.
Article 6, paragraph 1. Measures taken to limit exposure of workers to benzene. The Committee notes the Government’s statement that, according to Regulation 6 of the Factories (Benzene) Regulations, local exhaust ventilation is recommended on all possible escape routes during the process of manufacturing, handling and use of benzene and productions containing benzene. With reference to the terms of the Convention, the Committee notes that according to this Article all necessary measures shall be taken in this respect. The Committee requests the Government to take adequate measures, including considering a regulation of this issue in the context of the legislative reform referred to above (paragraph 3 above), to ensure that benzene vapours are removed from the working environment when the work processes cannot be carried out in an enclosed system, in accordance with this Article of the Convention.
Article 6, paragraph 2. Maximum levels of concentration of benzene in the air at places of work. The Committee notes that, according to the Factories (Benzene) Regulations, the permitted concentration of benzene in the air of the places of work is 25 parts per million or 80 mg/m3, which corresponds to the limit referred to in Article 6(2) of the Convention. The Committee wishes, however, to draw the Government’s attention to the fact that, since the adoption of this Convention in 1971, scientific knowledge has evolved. According to up to date scientific knowledge reflected in, for example, the limits recommended by the American Conference of Industrial Hygienists (ACGIH) are notably lower, and are presently recommended to be at a maximum of 0.5 parts per million or 0.6 mg/m3. Against this background, the Committee requests the Government to provide further information on the maximum limit value applied in practice for occupational exposure to benzene.
Article 10, paragraph 1. Medical examinations. The Committee notes that, according to the Government, effect is given to Article 10(1) and (2) by paragraphs 2 and 3 of the Factories (Benzene) Regulations and that, in practice, the Occupational Health, Safety and Research Bureau is often called upon to carry out such examination as they have the competent personnel and laboratories. Against this background, the Committee requests the Government to provide further information on the number of medical examinations carried out and their periodicity.
1. The Committee notes the information contained in the Government’s report, including partial responses to the Committee’s previous comments.
2. Article 2 of the Convention. Use of substitute products. The Committee notes that the Government refers to articles 7(1) and 7(2) of the Factories (Benzene) Regulations, according to which the National Occupational Safety and Health Information Centre (CIS) is required to offer advice on how to use harmless or less harmless substitute products instead of benzene or products containing benzene and the Department of Occupational Safety and Health Services is charged to transmit such information to employers.

Against this background, the Committee requests the Government to provide further information on the maximum limit value applied in practice for occupational exposure to benzene.
6. Article 8. Personal protective equipment. The Committee notes that the report is silent as regards its previous comment on this issue and reiterates its request to the Government to provide information on how it is ensured that workers who, for special reasons, may be exposed to concentrations of benzene in the air of places of employment which exceed the prescribed maximum are protected against the risk of inhaling benzene vapour.
7. Article 10, paragraph 1. Medical examinations. The Committee notes that, according to the Government, effect is given to article 10, paragraphs 1 and 2 by paragraphs 2 and 3 of the Factories (Benzene) Regulations and that, in practice, the Occupational Health, Safety and Research Bureau is often called upon to carry out such examination as they have the competent personnel and laboratories. Against this background, the Committee requests the Government to provide further information on the number of medical examinations carried out and their periodicity.
8. Article 14(c) and Part IV of the report form. Application in practice and inspection reports. The Committee notes that the inspectors are responsible for the supervision of the application of the Convention and that the Department of Occupational Safety and Health Services has established an occupational hygiene unit to provide training to the inspectors in order for them to carry out their duties. The Committee requests the Government continue to provide information on labour inspections and in particular, information on the number of inspections carried out, the number and nature of infringements found and any actions taken as a result.
The Committee notes with regret that the Government’s report has not been received. It hopes that a report will be supplied for examination by the Committee at its next session and that it will contain full information on the matters raised in its previous direct request, which read as follows:
The Committee notes the information provided by the Government in reply to its direct request. It would draw the Government’s attention to the following points.
1. Article 4, paragraph 2, of the Convention. The Committee notes the Government’s indication to the effect that inspectors advise the employers to provide sufficient and effective means to filter out the vapours from the working environment in order to ensure the removal of benzene vapour in the event that the work process cannot be carried out in an enclosed system, in accordance with regulations 7(1) and 7(2) of the Factories (Benzene) Regulations. It further notes that the inspectors ensure that processes, where such chemicals are used, are carried out in an enclosed system. The Committee requests the Government to specify the abovementioned means used to remove benzene vapours from the working environment.
2. Article 6, paragraph 3. The Committee notes the Government’s indication that the Department of Factories, being the competent authority, has no equipment to measure the concentration of benzene in the air of places of employment, but that some factory inspectors have been trained in the use of such equipment. It further notes that directions for measuring benzene in the air of places of employment will be issued when the equipment is made available and that these directives will be supplemented by a series of workshop demonstrations. The Committee hopes that the lacking equipment will be available soon and that the Government will take appropriate action in this request to guarantee the carrying out of these measurements indispensable to evaluate the concentration of benzene in the air at workplaces. It requests the Government to keep it informed on the progress made in this regard.
3. Article 8, paragraph 2. The Committee notes the Government’s indication to the effect that administrative measures have been taken to limit the duration of exposure to the possible minimum and that employers have provided adequate protective equipment and clothing against the risk of inhaling benzene and its products or absorbing them through the skin. The Committee requests the Government to specify the administrative measures providing for a limitation of exposure in the case set out in Article 8, paragraph 2, of the Convention.
4. Article 10, paragraph 1. The Committee notes the Government’s indication that though competent laboratories exist, they have not been fully utilized due to the nature of their operations and mandate. It further notes that the Government has not yet taken measures to ensure that the required medical examinations under the Convention are carried out by qualified physicians, approved by the competent authority, for lack of specialized physicians in the country. However, ordinary medical examinations are conducted by general physicians at the request of the employer as directed by the Department. Nevertheless, the Government has taken into consideration the Committee’s preceding comment regarding the measures to be taken in order to meet the requirements of this paragraph of the Convention. The Committee accordingly hopes that the Government will take the necessary steps in the near future to ensure that medical examinations will be carried out under the responsibility of a qualified physician, approved by the competent authority, and that the assistance of competent laboratories is received, as appropriate, in accordance with this provision of the Convention. The Committee also hopes that the Government will indicate, in its next report, the progress achieved in this regard.
5. Article 14(c). The Committee notes that inspections are carried out every three months by qualified and graduated inspectors with industrial experience under the auspices of the Factories Department, but that they could not measure the level of benzene in the factories concerned due to the lack of equipment. The Committee therefore requests the Government to explain the manner in which these inspections are carried out under these circumstances and, in particular, to indicate the means utilized by the inspectors in order to evaluate the degree to which the Convention is applied in practice.
The Committee reiterates its hope that the Government will soon be able to take the necessary action to ensure the full application of the Convention.
The Committee notes the information provided by the Government in reply to its direct request. It would draw the Government's attention to the following points.
1. Article 4, paragraph 2, of the Convention. The Committee notes the Government's indication to the effect that inspectors advise the employers to provide sufficient and effective means to filter out the vapours from the working environment in order to ensure the removal of benzene vapour in the event that the work process cannot be carried out in an enclosed system, in accordance with regulations 7(1) and 7(2) of the Factories (Benzene) Regulations. It further notes that the inspectors ensure that processes, where such chemicals are used, are carried out in an enclosed system. The Committee requests the Government to specify the abovementioned means used to remove benzene vapours from the working environment.
2. Article 6, paragraph 3. The Committee notes the Government's indication that the Department of Factories, being the competent authority, has no equipment to measure the concentration of benzene in the air of places of employment, but that some factory inspectors have been trained in the use of such equipment. It further notes that directions for measuring benzene in the air of places of employment will be issued when the equipment is made available and that these directives will be supplemented by a series of workshop demonstrations. The Committee hopes that the lacking equipment will be available soon and that the Government will take appropriate action in this request to guarantee the carrying out of these measurements indispensable to evaluate the concentration of benzene in the air at workplaces. It requests the Government to keep it informed on the progress made in this regard.
3. Article 8, paragraph 2. The Committee notes the Government's indication to the effect that administrative measures have been taken to limit the duration of exposure to the possible minimum and that employers have provided adequate protective equipment and clothing against the risk of inhaling benzene and its products or absorbing them through the skin. The Committee requests the Government to specify the administrative measures providing for a limitation of exposure in the case set out in Article 8, paragraph 2, of the Convention.
4. Article 10, paragraph 1. The Committee notes the Government's indication that though competent laboratories exist, they have not been fully utilized due to the nature of their operations and mandate. It further notes that the Government has not yet taken measures to ensure that the required medical examinations under the Convention are carried out by qualified physicians, approved by the competent authority, for lack of specialized physicians in the country. However, ordinary medical examinations are conducted by general physicians at the request of the employer as directed by the Department. Nevertheless, the Government has taken into consideration the Committee's preceding comment regarding the measures to be taken in order to meet the requirements of this paragraph of the Convention. The Committee accordingly hopes that the Government will take the necessary steps in the near future to ensure that medical examinations will be carried out under the responsibility of a qualified physician, approved by the competent authority, and that the assistance of competent laboratories is received, as appropriate, in accordance with this provision of the Convention. The Committee also hopes that the Government will indicate, in its next report, the progress achieved in this regard.
5. Article 14(c). The Committee notes with interest that inspections are carried out every three months by qualified and graduated inspectors with industrial experience under the auspices of the Factories Department, but that they could not measure the level of benzene in the factories concerned due to the lack of equipment. The Committee therefore requests the Government to explain the manner in which these inspections are carried out under these circumstances and, in particular, to indicate the means utilized by the inspectors in order to evaluate the degree to which the Convention is applied in practice.
Referring to its observation on the Convention, the Committee requests the Government to include in its next report information on measures taken or envisaged in respect of the following:
1. Article 4, paragraph 2, of the Convention. The Committee requests the Government to indicate nay measures taken in practice to guarantee that "efficiency means" to ensure the removal of benzene vapour under regulation 7(2) of the Factories (Benzene) Regulations are equally safe as the use of an enclosed system, at least where benzene or products containing benzene are used as a solvent or diluent.
2. Article 6, paragraph 3. This particular provision requires the competent authority to issue directions on carrying out the measurement of the concentration of benzene in the air of places of employment. This provision is particularly important because paragraph 2 of the same Article would require employers to ensure that concentration of benzene in the air of places of employment should not exceed a maximum level to be fixed by the competent authority at a level not exceeding a ceiling value of 25 parts per million (80 mg/m3). While the Convention gives to the employer the obligation of ensuring that benzene in the air is controlled below a particular level, the manner by which such control is ensured must be provided for by the competent authority through appropriate instructions on how to measure benzene in the air. Article 6, paragraph 3, therefore, makes it possible for the required ceiling value level to be observed and properly monitored. The Committee notes that regulation 5 of the Factories (Benzene) Regulations of 1978 specifies the same ceiling value as the Convention. However, no provision refers to the issuance of instructions by the competent authority on how employers, through a particular mode of measurement, may keep the levels of benzene in the air in their respective factories within the required ceiling value. The Committee hopes that such a provision will soon be included in pertinent regulations so as not to render nugatory the requirement of keeping benzene in the air within the mandated ceiling value.
3. Article 8, paragraph 2. The Committee notes the provisions contained in regulations 8, 9 and 10 of the Factories (Benzene) Regulations concerning protection against skin contact and exposure to benzene or products containing benzene or its vapour and through the provision of personal protection and/or suitable protective clothing. However, with reference to cases when, for special reasons, workers may be exposed to concentration of benzene in the air, the Committee requests the Government to indicate the measures taken to limit the duration of exposure as low as possible.
4. Article 10, paragraph 1. The Committee requests for information on the practical application of regulation 14(2) of the Factories (Benzene) Regulation indicating, in particular, the extent to which assistance of competent laboratories are utilized, including measures adopted by the competent authority to ensure that the physicians conducting the medical examinations are qualified to undertake such examinations. The Committee, in this regard, brings to the attention of the Government the requirement under this particular provision of the Convention that medical examinations shall be carried out under the responsibility of a qualified physician, approved by the competent authority, and with assistance, as appropriate, of a competent laboratory.
5. Article 14(c). The Committee requests the Government to supply it with information on the manner by which inspection of establishments are carried out; the qualifications of inspectors carrying out inspection services in factories where benzene is present; and the measurement of benzene levels in such establishments.
The Committee hopes that the Government will soon be able to take the necessary action to ensure the full application of the Convention and that it would be able to indicate the progress made in this regard.
Article 7 of the Convention. The Committee notes with satisfaction that pursuant to its earlier comments an amendment to the Factories (Benzene) Regulations of 1978 has been made by Statutory Instrument No. 158 of 1993 to the effect that work processes involving the use or products containing benzene shall be carried out in an enclosed system, and where this is not practicable, efficient means shall be provided to ensure the removal of benzene vapour. The Committee is addressing a direct request to the Government concerning a number of other points.
I. The Committee notes the Government's statement in its latest report that it agrees with the Committee's previous comments as concerns the application of the Convention and that it would advise the ILO of the progress and developments made. The Committee, therefore, hopes that the necessary measures will be taken in the near future to ensure the application of Article 4, paragraph 2 of the Convention (prohibition of the use of benzene as a solvent or diluent unless the process is carried out in an enclosed system (and not area)), Article 7 (work processes involving the use of benzene generally to be carried out in an enclosed system as far as practicable, and where not practicable, the workplace shall be equipped with effective means to ensure the removal of benzene vapour), and Article 8, paragraph 2 (limitation on the duration of exposure to benzene vapour for workers who, for special reasons, are exposed to concentrations of benzene exceeding the maximum prescribed level). The Government is requested to indicate, in its next report, the progress made in this regard.
II. The Committee notes from the reply in the Government's report as concerns the application of Article 6, paragraph 3 of the Convention (instructions on carrying out the measurement of benzene in the air), that the Government is currently processing a request for ILO technical co-operation. The Committee hopes that the Government will, with the assistance of the ILO, soon be in a position to ensure the appropriate monitoring of the concentration of benzene in the air of places of employment by means of adequate instructions on the carrying out of the measurement of such concentrations. The Government is requested to indicate, in its next report, the progress made in this regard.
The Committee further notes the Government's statement in its report that the Government hopes that ILO technical assistance will enable it to improve the practical application of the Convention. The Committee hopes that the Government will take the necessary measures to improve the application of the Convention in practice and that it will ensure the enforcement of the provisions designed to give it effect, including, in particular, provisions for the medical examination of all workers concerned and the inspection of all workplaces where workers may be exposed to benzene or to products containing benzene. The Committee hopes that the Government will soon be able to indicate the progress made in this regard.
1. Statutory rules and orders to be made. In comments made for a number of years, the Committee has noted the absence of provisions giving effect to several important requirements of the Convention. Since 1979, the Government has referred to a planned general survey of working places where benzene is used; in its 1985 report, the Government indicated that this survey was to provide the information necessary for the full application of the Convention. The Committee notes with interest the Government's indication in its latest report that a general survey of the automobile industry where solvents are used has now been carried out with the assistance of the Zambia State Insurance Corporation Limited. The Committee accordingly hopes that the necessary measures will soon be taken to amend and supplement the Factories (Benzene) Regulations, 1978 so as to give effect to the following provisions of the Convention:
(a) Articles 4 and 7 of the Convention. Under Article 7 of the Convention, work processes involving the use of benzene or products containing benzene shall be carried out in an enclosed system as far as practicable, and where this is not practicable, the workplace shall be equipped with effective means to ensure the removal of benzene vapour. In the absence of such means of protection, the use of benzene and of products containing benzene shall be prohibited under Article 4, at least as a solvent or diluent. The Committee previously noted that Regulation 3 of the Factories (Benzene) Regulations, 1978 does not prohibit the use of benzene or products containing benzene but merely requires their replacement "whenever harmless or less harmful substitute products are available"; Regulation 7 apparently follows the language of article 7 of the Convention, except that it refers to "an enclosed area" instead of an enclosed system. The Committee recalls the Government's indications in its reports received in 1979 and 1985 that, in order to protect workers from harmful contaminants, Regulation 7 needed to be amended so as to read "enclosed system" instead of "enclosed area", and that this amendment would be introducted into paragraphs (1) and (2) of Regulation 7 after the general survey of working places was carried out. Consequently, this should now be done.
(b) Article 6, paragraph 3. Under Article 6, paragraph 2 of the Convention, the employer shall ensure that the concentration of benzene in the air of the places of employment does not exceed a ceiling value of 25 parts per million (80 mg/m3), and under paragraph 3, the competent authority shall issue directions on carrying out the measurement of the concentration of benzene in the air of places of employment. In its report received in 1979, the Government indicated that these directions would be given after carrying out the survey of working places where benzene may be still in use. The Committee notes the Government's indication in its latest report that, at the time of the visits to workplaces, the competent authority has been unable to carry out monitoring, and no measurements were taken due to lack of equipment. The Committee must point out that the responsibility for keeping the concentration of benzene in the air within the limits allowed under Article 6, paragraph 2 is to rest with the employer; it follows that the measurement mentioned in Article 6, paragraph 3 is also to be ensured by the employer, under directions to be issued by the competent authority. The Committee accordingly hopes that the necessary instructions will now be issued.
(c) Article 8, paragraph 2. Under this provision, workers who for special reasons may be exposed to concentrations of benzene in the air of places of employment which exceed the maximum referred to in Article 6, paragraph 2 shall be provided with adequate means of personal protection against the risk of inhaling benzene vapour. This is also called for by Regulation 9 of the Factories (Benzene) Regulations, 1978. However, Article 8, paragraph 2 moreover provides that the duration of exposure shall be limited as far as possible. In its report received in 1979, the Government indicated that to date no cases of employment which exceeded the maximum allowable concentration had been reported; however, when the survey was complete, where appropriate, the duration of exposure to high concentrations would have to be set. The Committee notes that at the time of the survey, the concentration of benzene could not be measured in the absence of the necessary equipment; it accordingly hopes that the competent authority will now, besides issuing the necessary instructions for measurement already referred to under Article 6, paragraph 3, also set appropriate limits to the duration of exposure to high concentrations of benzene in the air.
2. Application in practice and enforcement of the Convention. Under Article 14(a) of the Convention, the Government shall take such steps as may be necessary to give effect to the provisions of the Convention and, under Article 14(c), appropriate inspection is to be carried out. The Committee notes with interest that the general survey of the automobile industry carried out with the help of the Zambia State Insurance Corporation involved 40 motor vehicle repair workshops, where the inspection teams inspected spray painting booths and paint storage facilities. The Committee notes that the inspection teams gave advice on mechanical exhaust ventilation systems and hazards associated with the use of solvents including benzene, advised the factory occupiers not to use benzene as provided in the Factories (Benzene) Regulations, and advocated the use of enclosures, mechanical exhaust systems and, in the last resort, personal protective equipment, as provided by the Regulations. The Committee, however, observes that the inspection teams, hampered as they were by the absence of measuring equipment, appear not to have been in a position to enforce, where necessary, the application of the relevant regulations. Moreover, working places where benzene may be used outside the 40 motor vehicle repair shops included in the survey appear not to have been inspected. In this connection, the Committee also recalls the Government's indication in its report received in 1985 that medical examinations are carried out at one paint manufacturing factory; however, Article 9, paragraph 1 of the Convention as well as Regulation 14 of the Factories (Benzene) Regulations, 1978 provide for pre-employment medical examination and periodical re-examination of every person employed in processes involving exposure to benzene or products containing benzene. The Committee hopes that the necessary measures will be taken to improve the application in practice and enforcement of provisions designed to give effect to the Convention, including provisions for the medical examination of all workers concerned and the inspection of all workplaces where workers may be exposed to benzene or to products containing benzene, and that the Government will report on the action taken.
1. In earlier comments, the Committee noted the Government's indication in its 1985 report that a general survey of working places where benzene is used was to provide the information necessary for the full application of the Convention. The Committee notes from the Government's latest report that the general survey, which was started with the assistance of the Lusaka Urban District Council could not be completed due to a lack of qualified personnel, transport and relevant measuring equipment. The Government, however, considers that a thorough survey of working premises where benzene is used is still necessary for effective enforcement of the Factories (Benzene) Regulations and the application of the requirements of the Convention. The Committee hopes that the appropriate priority will be given to this project and that the Government will soon be in a position to indicate that the survey has been completed.
2. For a number of years, the Committee has noted the absence of measures to give effect to important requirements of the Convention. The Committee hopes that the necessary steps will be taken in the near future so as to ensure the application of Article 4 (prohibition of the use of benzene as a solvent or diluent unless the process is carried out in an enclosed system), Article 6, paragraph 3 (directions on carrying out the measurement of benzene in the air), Article 7, paragraph 1 (work processes involving the use of benzene to be carried out in an enclosed system), and Article 8, paragraph 2 (personal protective equipment against the risk of inhaling benzene vapour for workers exposed to excessive concentrations of benzene). The Committee hopes that the Government will soon be able to indicate progress made in this regard. [The Government is asked to report in detail for the period ending 30 June 1990.]
