Reduction of risk to health and safety through administrative or engineering measures.
- Best to worst ways:
- elimination or substitution (replacing a hazardous material or process with a less hazardous one)
- process or equipment modification (isolation - containing or limiting access to the hazardous process)
- local exhaust ventilation (esp. for chemical and heat-related hazards)
- PPE - personal protective equipment (e.g. respirators, gloves, glasses, hats, harnesses, boots)
(Administrative strategies such as rotating workers through dangerous jobs to limit any individual’s aggregate exposure - such as to radiation - sometimes have a role as well.)
(Regulations, compare to internal company standards, specific programs in place for confined space entry, medical monitoring, hearing protection)
