Question

The main objective of an On-Site Emergency Plan is to:

1. A. Ensure orderly evacuation and control of an incident within the plant boundary (Correct answer)
2. B. Coordinate response only for off-city casualties
3. C. Replace routine maintenance schedules
4. D. Only display panic-buttons and sirens

Correct Answer

Option A — Ensure orderly evacuation and control of an incident within the plant boundary

Detailed Solution & Explanation

The correct answer is Ensure orderly evacuation and control of an incident within the plant boundary.

Key Points

• The defining feature of an On-Site Emergency Plan is its boundary: it deals with an incident inside the factory premises, aiming to control the emergency, rescue and treat casualties, and evacuate personnel in an orderly way while limiting damage.
• Its counterpart, the off-site plan, takes over where effects cross the fence line into the surrounding community.
• The rejected options either look outward (off-city casualties), confuse the plan with routine maintenance, or reduce it to hardware — panic buttons and sirens are components, not the objective.

Additional Information

• A complete on-site plan identifies the incident controller and site main controller, establishes an emergency control centre, sets out alarm and communication arrangements, assembly points and escape routes, rescue and firefighting duties, medical arrangements and mutual-aid agreements with neighbouring units.
• The plan must be tested by mock drills, typically at least once every six months, and revised in the light of what the drills expose. An untested plan is generally worthless in a real event.
• It also covers restoration and rehabilitation — making the plant safe and resuming operations — which is often overlooked in exam answers.
• The occupier must keep the plan current and ensure that every worker knows their role in it, not merely that a document exists.
