Emergency action plans on construction sites for the CHST

What the rules point to

The construction rule for employee emergency action plans is 29 CFR 1926.35, and fire protection and prevention has its own Subpart F. Read both in your own copy of 1926. We give section numbers here and explain the ideas in our own words, never the standard's text.

What a good plan answers

A plan has to answer a short list of questions before an emergency, not during one.

• How do people find out? An alarm that every worker can hear or see, including in noisy areas and enclosed work. A plan fails when half the crew never learns there is a fire.
• Where do people go? Marked exit routes and assembly points that stay open as the site changes. Construction sites change weekly, so routes must be reviewed as the building and the layout change.
• Who is in charge? Named roles for calling emergency services, guiding crews and accounting for everyone.
• How does everyone get counted? A roster or sign-in that is current enough to know who is on site today, including subcontractors and visitors.
• Who does what for special hazards? Confined space rescue, fall rescue and hazardous material releases need specific actions and trained people.
• How do workers learn it? Orientation for new workers and refreshers when the plan changes.

Emergency action plan vs fire prevention plan

They answer different questions, and an exam stem will often test whether you can tell which is which.

Both matter, and a site needs both. A good fire prevention plan reduces the chance that the emergency plan is ever used.

Rescue is part of the plan

Do not rely on 911 as the plan for a worker in trouble inside a space or on a fall arrest system. Response time matters, so the plan needs rescue arrangements before the work starts. The confined spaces guide explains why rescue has to be arranged ahead of entry, and the fall protection guide covers the same idea for arrest systems.

How the exam builds these questions

Scenario stems usually give you a site, a hazard and a problem, and ask for the best action. Patterns to expect:

• Alarm and communication. A worker cannot hear the alarm over equipment. The strongest answer adds a visual signal or other means, rather than telling the worker to listen harder.
• Changing site. A staircase is closed and the posted route now leads to a blocked exit. The plan must be updated and communicated, not left until the next audit.
• Accounting. After an evacuation, no one knows whether a subcontractor's crew is out. The answer points to a current roster and a person responsible for the count.
• First action. Get people to safety and call for help before you try to fight a fire, unless trained and equipped and it is small and safe to try.

Practice by writing one

Pick a project you know. In five lines, write the alarm, the routes, the assembly point, the head count and the person in charge. Then ask what changes in week six, when the site layout looks nothing like week one. If you can write it for your own site, you can reason about it for any scenario.

FAQ

Is a written emergency action plan always required?

The rules set when a written plan is required and when a smaller site may communicate orally. Check 1926.35 in your own copy and the standards that apply to your hazards.

Who should be trained on the plan?

Every worker on site, with extra training for anyone assigned a role such as head counter or rescue responder.

How often should a plan be reviewed?

Whenever the site, the work or the people change enough to alter routes or roles, which on a building under construction is often.
