Question

Which of the following is not a hazard that can be created by electrical power? Select one: a. Arc blasts and arc burns b. Electrocutions c. Heat materials to a point that creates combustion d. Ignite combustible vapors e. Spontaneous combustion

Answer 1

Answer: e) Spontaneous combustion

Explanation: Spontaneous combustion is the mechanism of self occurring ignition.It is caused by the excessive temperature which raises the heating and thus high temperature is caused to start the ignition known as auto-ignition.

Other options are incorrect because arc burst and burns is the excess amount of electrical power that can result in equipment damage. Electrocutions causes the severe electric shocks.

Combustible vapors ignition and heat materials for combustion can be obtained by using the source of electrical power for ignition.Thus, the correct option is option (e).
