F. Right‐size appliances An evaluation of how the lab is using its appliances will help identify equipment that is being underutilized. Autoclaves, incubators, and ovens that are not being used to their full capacity may be shared with other labs to reduce the total number of appliances in the building. Alternative smaller countertop versions of appliances may also be used. Ensure that occupants use appliances properly. Incubators, for example, should not be used as refrigerators, since they use five to 10 times more energy. Use smaller versions of both appliances if both are needed. G. Chemical use Where hazardous chemicals are being used, look for less toxic alternatives. Reduce the scale of procedures so less chemicals are being consumed, whilst still achieving the same result.

Characteristics of the activity/interior Representative activities/interiors Interiors rarely visited with visual tasks limited to movement and orientation Interiors requiring intermittent use with visual tasks limited to movement, orientation and coarse detail. Any continuously occupied interior where there are no tasks requiring perception of other than course detail. Occasional reading of clearly printed documents for short periods. Continuously occupied interiors with moderately easy visual tasks with high contrasts or large detail. Areas where visual tasks are moderately difficult with moderate detail or with low contrasts. Areas where visual tasks are difficult with small detail or with low contrast. Corridors; cable tunnels; indoor storage tanks; walkways. Staff change rooms; live storage of bulky materials; dead storage of materials needing care; locker rooms; loading bays.
