Answer:
Osha require employers to construct and install the following to minimize electrocution hazards:
- Insulators
- Guarding Systems
- Grounding Systems
-Circuit protection devices
Explanation:
Imsulators
- Insulators are materials that do not conduct electricity. They are used to coat metals and other conductors to prevent or reduce the possibility of current flow that can cause electrocution.Example of insulators include rubber,mica, plastics e.t.c.
- Guarding System
Guarding systems basically involves granting restricted access to electrical equipments especially those operating at 50 volts and above.Guarding can be achieved by placing electric equipments in restricted areas or even enclosing them. A conspicuous warning label is usually place in such areas where the electric eqipment is situated.
- Grounding System
A grounding system serves to create a path of low resistance from the electric equipment to the earth so that excess voltage build up on the eqipment is prevented as it will be discharged through the created path of low resistance to the earth. The grounding system is essentially a secondary protective measure.It does not guarantee against electrocution.
-Circuit Protection devices
Circuit protection devices serve to reduce or completely obstruct current flow when there is overload,ground fault or a short circuit in the electric system wiring.Example of these devices include circuit breakers, fuses, ground-fault circuit interrupters and arc-fault circuit interrupters.
