8.2. Exposure controls
8.2.1. Appropriate
engineering controls
Engineering controls are used to remove a hazard or place a barrier between the worker and the hazard. Well-designed engineering controls can
be highly effecve in protecng workers and will typically be independent of worker interacons to provide this high level of protecon.
The basic types of engineering controls are:
Process controls which involve changing the way a job acvity or process is done to reduce the risk.
Enclosure and/or isolaon of emission source which keeps a selected hazard "physically" away from the worker and venlaon that strategically
"adds" and "removes" air in the work environment.
8.2.2. Personal protecon
Eye and face protecon
Safety glasses with side shields
Chemical goggles.
Contact lenses may pose a special hazard; so contact lenses may absorb and concentrate irritants. A wrien policy document, describing the
wearing of lenses or restricons on use, should be created for each workplace or task. This should include a review of lens absorpon and
adsorpon for the class of chemicals in use and an account of injury experience.
Skin protecon See Hand protecon below
Hands/feet protecon When handling sealed and suitably insulated cylinders wear cloth or leather gloves.
Body protecon See Other protecon below
Other protecon
Posive pressure, full face, air-supplied breathing apparatus should be used for work in enclosed spaces if a leak is suspected or the primary
containment is to be opened (e.g. for a cylinder change)
Air-supplied breathing apparatus is required where release of gas from primary containment is either suspected or demonstrated.
Protecve overalls, closely fied at neck and wrist.
Eye-wash unit.
Ensure availability of lifeline in confined spaces.
Staff should be trained in all aspects of rescue work.
Thermal hazards Not Available
Respiratory protecon
Type AX Filter of sufficient capacity. (AS/NZS 1716 & 1715, EN 143:2000 & 149:2001, ANSI Z88 or naonal equivalent)
Where the concentraon of gas/parculates in the breathing zone, approaches or exceeds the "Exposure Standard" (or ES), respiratory protecon is required.
Degree of protecon varies with both face-piece and Class of filter; the nature of protecon varies with Type of filter.
