For an occupational group that has an asterisk (*) in the Environmental Conditions ratings, refer to the Remarks section of that group for an explanation.
The work performed is carried out indoors in a regulated environment, indoors in an unregulated environment, outdoors or in a vehicle. In many occupations, the Main Duties may be performed in more than one location. Therefore, a group may have more than one Location code, for example:
An inside work environment where the temperature or humidity may be considerably different from normal room conditions. In some groups, the nature of the duties affects the temperature or humidity of the work environment.
An outdoor work environment where the worker is exposed to variations in weather conditions and seasonal weather patterns.
An interior space in any form of vehicle or in the cab of heavy equipment operated by the worker.
Potential hazards to which the worker may be exposed. The codes provide an indication of the type(s) of hazard(s) most likely to be present in the workplace environment. They are not a measure of frequency, duration or degree of exposure to hazards, but an indication of the presence or absence of a particular hazard in the work environment.
Exposure to any chemical that may endanger health through inhalation, absorption or ingestion, contact with skin or eyes, or any chemical with the potential for fire or explosion. Substances may be in forms such as solids, liquids, gases, aerosols or particles.
Exposure to infectious bacteria and viruses as a result of indirect contact with, or direct handling of, infectious materials or micro-organisms that may cause illness.
Working near or with equipment, instruments, machinery or power/hand tools that may be a potential source of accident or injury.
Exposure to electrical circuitry, high tension wires, transformers or other equipment that may be a potential source of electrical shock.
Exposure to ionizing radiation such as X-rays and radioactive substances or non-ionizing radiation such as radio frequencies and infrared, ultraviolet or visible light that may affect health adversely.
Exposure to flying particles and falling objects in the work environment that pose the risk of bodily injury. Flying particles refer to particles such as wood chips, metal particles and rock chips generated by the handling, crushing, grinding, rapid impact or explosion of materials.
Exposure to fire (rather than exposure to flammable substances that may ignite), to emissions of steam or to intensely hot surfaces that are potential sources of injury.
Working in locations that are inherently treacherous and are potential sources of injury. Such work locations include construction sites, underground sites, erected support structures and marine environments.
Work conditions that create disturbances but are not hazardous. In general, these conditions create discomfort, but are not direct sources of injury. In extreme instances, however, these conditions might cause injury.
Work that produces sufficient noise – constant or intermittent – to cause marked distraction or possible loss of hearing.
Work that produces an oscillating or quivering motion of the body.
The presence of noxious, intense or prolonged odours in the work environment.
The presence of non-poisonous airborne particles such as textile dust, flour, sand, sawdust and feathers in the work environment.
Work that involves contact with water or other liquids.
