10. Control of exposure to HCS

 

 

1) An employer shall ensure that the exposure of an employee is either prevented or, where this is not reasonably practicable, adequately controlled: Provided that
a) where there is exposure for which there is a recommended limit, the control of the exposure shall be regarded as adequate if the level of exposure is below that limit or if the relevant area is zoned and the level of exposure is reduced to below that recommended limit by means of adequate personal protective equipment only after the level has been reduced to as low as is reasonably practicable by any other means than personal protective equipment; or
b) where there is exposure for which there is a control limit, the control of the exposure shall be regarded as adequate if the exposure is at a a level as low as is reasonably practicable below that control limit: Provided that in the case of temporary excursions above the control limit, the employer shall ensure:
i) that the excursion is without a significant risk from exposure;
ii) that the excursion is not indicative of a failure to maintain adequate control;
iii) that during the excursion, the area is temporarily demarcated as prescribed in regulation 8(b) ; and
iv) the provisions of regulation 11 are complied with.

 

2) Where reasonably practicable, the employer shall control the exposure of an employee:
a) by limiting the amount of an HCS used which may contaminate the working environment;
b) by limiting the number of employees who will be exposed or may be exposed;
c) by limiting the period during which an employee will be exposed or may be exposed;
d) by using a substitute for an HCS;
e) by introducing engineering control measures for the control of exposure, which may include the following:
i) Process separation, automation or enclosure;
ii) the installation of local extraction ventilation systems to processes, equipment and tools for the control of emissions of an airborne HCS;
iii) use of wet methods; and
iv) separate workplaces for different processes;
f) by introducing appropriate work procedures which an employee must follow where materials are used or processes are carried out which could give rise to exposure of an employee and that procedures shall include written instructions to ensure:
i) that an HCS is safely handled, used and disposed of;
ii) that process machinery, installations, equipment, tools and local extraction and general ventilation systems are safely used and maintained;
iii) that machinery and work areas are kept clean; and
iv) that early corrective action can be readily identified.

 

3) An employer shall ensure that the emission of an HCS into the atmosphere comply with the provisions of the Atmospheric Pollution Prevention Act, 1965 (Act No. 45 of 1965).
