17、ration of timber treatment plants 1 Scope This standard serves as a practical guide on occupational health and safety and environmental aspects in and around timber treatment plants with the intention to reduce health and safety and environmental risks. It is applicable to any treatment process (as
18、described in SANS 10005) in which waterborne preservatives, flame-retardants, anti-sapstain chemicals, organic solvent-based preservatives or oil-borne preservatives are used. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisio

35、ent or employer Every employer shall provide and maintain, as far as is reasonably practicable, a working environment that is safe and without risk to the health of his employees. It remains the responsibility of management to ensure that sound environmental and occupational health and safety manage
36、ment policies are established and implemented in timber treatment plants. Health and safety representative(s) and, when relevant, health and safety committees, shall be appointed in accordance with the safety legislation (see foreword). Amdt 1 Due to the nature of the chemicals and the equipment use
37、d for the treatment of timber, health and safety risk assessments and environmental impact assessments shall be carried out at all timber treatment plants. Such assessments ensure the health and safety of the employers as required by the safety legislation (see foreword), and also sound environmenta
38、l management in accordance with the relevant environment legislation (see foreword). Amdt 1 4.2 Employees Every employee shall take reasonable care for the health and safety of himself and of other persons who may be affected by his actions or omissions. Employees shall, with regard to any duty or r
39、equirement imposed on his employer by any prevailing legislation, for example environmental and occupational health and safety, cooperate with such employer to enable that duty to be performed or requirement to be complied with. 5 Occupational health risk assessments 5.1 General Risk assessments sha
40、ll be carried out on all chemical processes and in all other areas where the health of workers is important, for example personal hygiene facilities such as toilets, locker rooms, washrooms and dining halls. The risk assessments shall identify the hazards and evaluate the risks associated with the t
41、reatment chemicals to the health of the employees, and the steps that need to be taken to minimize the risks. 5.2 Assessment of potential exposure After consultation with the health and safety representative or health and safety committee, the employer shall arrange an immediate assessment to be don
42、e to determine if any employee is exposed to any HCS. These assessments shall be done at intervals not exceeding two years and shall be done in accordance with the relevant regulations of the safety legislation (see foreword). Amdt 1 5.3 Air monitoring Where the inhalation of HCS in preservative tre
43、atment chemicals is a risk, a measurement programme (air sample analysis) of airborne concentrations of the HCS shall be established and carried out in accordance with the relevant regulation of the of the safety legislation (see foreword). The levels of chemicals that workers are exposed to shall b
44、e continuously monitored to ensure that exposure limits are not exceeded. Amdt 1 The air monitoring measurement programme shall be carried out by an inspection authority approved in terms of the safety legislation (see foreword) or by a person whose ability to do the measurements is verified by an a
45、pproved inspection authority. Amdt 1 SANS 10255:2009 Edition 2.1 7 5.4 Medical surveillance Medical surveillance is essentially medical testing that is carried out to inform the employer which workers are being affected or are likely to be affected as a result of exposure to the chemicals in their w
46、ork place. Medical surveillance shall be carried out when a) workers are exposed to HCS listed in the regulations contained in the safety legislation (see foreword); Amdt 1 b) the risk assessment on the chemical processes and air monitoring indicates that the health of workers is at risk; and c) a q
47、ualified occupational health practitioner recommends that the relevant workers be placed under medical surveillance. The medical surveillance programme shall be carried out in accordance with the relevant regulation of the safety legislation (see foreword) and can contain biological monitoring of ex
48、posure (biological monitoring and biological effects monitoring) and medical screening of workers. Biological monitoring of exposure and medical screening shall be done by a qualified medical practitioner or nurse with the necessary occupational health qualifications. Amdt 1 5.5 Occupational hygiene
49、 5.5.1 Facilities The following facilities shall be provided in accordance with the relevant regulations of the safety legislation (see foreword) and the provisions of the relevant legislation and shall be kept in good working order and in hygienic condition at all times: Amdt 1 a) ablution blocks with showers, toilet facilities, wash basins, soap and water; b) lockers and change rooms; and c) emergency showers and eyewash facilities. 5.5.2 Emergency facilities Emergency showers and eyewash facilities shall be installed within the bunded area (see 6.3.2).
