alleryStart learning →Electricity presents which two hazards?
AThermal hazard and shock hazard
BThermal hazard and static hazard
CMagnetic hazard and shock hazard
DChemical hazard and shock hazard
Answer & Solution
Correct answer: A. Thermal hazard and shock hazard
1. One hazard comes from energy being converted to heat faster than it can be carried away.
2. That is the thermal hazard, and a fire started inside a wall is the classic case.
3. The other comes from current passing through a person, which is the shock hazard.
4. Shocks range from merely painful to lethal, so the two hazards are treated separately.
