Question

List the (3) basic hazardous areas in machinery require safeguarding?

Answer 1

The three basic hazardous areas in machinery that require safeguarding are electrical hazards, mechanical hazards, and chemical hazards.

Step-by-step explanation:

The three basic hazardous areas in machinery that require safeguarding are:

1. Electrical hazards: These include thermal hazards (excessive power) and shock hazards (current through a person). To prevent these hazards, electrical safety systems and devices are employed, such as circuit breakers and fuses that interrupt excessive currents.
2. Mechanical hazards: These hazards involve moving parts of machinery that can cause injuries to workers. Safeguards for mechanical hazards include machine guarding, such as installing barriers, emergency stops, and interlock systems.
3. Chemical hazards: Machinery may involve the use of hazardous chemicals that can pose health risks. Proper hazardous material handling, storage, and ventilation systems should be in place to protect workers from chemical hazards.
