EXAMPLES OF HIERARCHY OF CONTROLSafety Measure ExplanationElimination: Eliminate the use of the substance use a physical process instead of a chemical process e.g. using ultrasound to clean equipment instead of a process involving chemicals;

using clips/bolts or nails instead of adhesive.

Substitution: Use a safer substance or a safer form of the substance

Safer substance use detergent instead of chlorinated solvent for cleaning use water-based chemicals instead of solvent-based use chemicals where compatible

Safer form or process paint with a brush instead of spraying purchase a substance in a safer form

Isolation: Separate people or property from the substance by distanceor barriers

use closed systems isolate the process to one room with restricted access or use appropriate barriers/screens to separate substances distance workers from substances/processes through the use of remote controls distance property, incompatible chemicals and ignition sources (e.g. flames, sparks) from goods

Engineering: Use physical controls (such as plant/equipment) that eliminate or reduce the generation of substances; suppress or contain substances; or limit the area of contamination in the event of spills and leaks.

use fully or partially enclosed ventilation booths fully or partially enclose the process with exhaust extraction use local exhaust or natural ventilation systems (e.g. air ducts, open doors/windows) design buildings that are: compatible with the intended goods; made of non-combustible construction as far as is practicable; designed

to reduce contamination use bunding to contain spillage install drains, tanks or sumps to cope with spilled material install automatic fire protection and chemical suppression systems

Administration: Use safe work practices including good housekeeping.

reduce the amount of property or the number of employees exposed reduce the duration and/or frequency of exposure e.g. through job rotation reduce the amount of goods/products stored and used ensure safe interim storage of wastes/products (e.g. labeled properly in suitable containers stored away from people, the environment,

incompatible chemicals, ignition sources etc) vacuum or wet sweep to suppress dust being generated cover containers and make sure lids are attached clean up spills immediately (includes provision of suitable aids, equipment and isolate floor and stromwater drains) ensure no eating, drinking or smoking in areas where substances are used provide suitable washing facilities provide First Aid facilities instruct employees on how to use substances safely

Personal Protective Equipment (PPE): Provide protective clothing and equipment for employees, supervisors and visitors. NB: items must be compatible with chemical(s) being used/stored

overalls, aprons, gowns, chemical resistant suits footwear (enclosed shoes, safety boots) gloves chemical resistant glasses (safety glasses) face shields/masks, respirators . full/partial head protection
