The layout plan includes:
- All possible emergencies, consequences, required actions, written procedures, and the resources available.
- Detailed lists of emergency response personnel, including their cell phone numbers, alternate contact details, and their duties and responsibilities
- Floor plans.
- Large scale maps showing evacuation routes and service conduits (such as gas and water lines).
- Since a sizable document will likely result, the plan should provide staff members with separate written instructions about their particular emergency response duties.
After having identified the hazards, the possible major impacts of each should be itemized, such as:
- Sequential events (for example, a fire after an explosion)
- Damage to plant infrastructure.
- Loss of vital records/documents
- Damage to equipment.
- Disruption of work.
Based on these events, the required actions are determined, such as:
- Declare an emergency.
- Sound the alert.
- Evacuate danger zone.
- Close main shutoffs.
- Call for external aid.
- Initiate rescue operations.
- Attend to casualties.
- Fight fire.
Also, consider what resources are required and their location, such as:
- Medical supplies.
- Power generators.
- Breathing Respirators.
- Chemical and radiation detection equipment.
- Emergency protective clothing.
- Firefighting equipment.
- An ambulance.
- Rescue equipment.
