The Definition of Muster Point

Definition of Muster Point

A muster point, also called an assembly point or evacuation assembly area, is a designated safe location where workers, contractors and visitors gather after evacuating a building or work area during an emergency. Its main purpose is to make sure everyone can be quickly accounted for, so that emergency responders know whether anyone is missing and may still be inside.

Muster points are used for fires, gas leaks, chemical releases, bomb threats, severe weather and other emergencies. Large or high-risk sites, such as refineries, offshore platforms, mines and chemical plants, often have several muster points, including primary and alternate locations in case one is unsafe.

In the United States, OSHA's emergency action plan standard, 29 CFR 1910.38, requires employers to have procedures to account for all employees after an evacuation. Muster points and headcount procedures are the usual way to meet this requirement. Similar duties exist under fire safety and emergency planning laws in the UK, Canada and Australia.

Choosing a Muster Point

• Safe distance: far enough from the building or hazard to protect people from fire, smoke, falling debris, explosions or toxic releases.
• Out of the way: away from routes emergency vehicles will use and from areas where responders will set up.
• Easy to reach: accessible by clear evacuation routes, including for people with disabilities.
• Weather and wind: considers prevailing wind direction for sites with gas or chemical hazards, and offers alternatives upwind.
• Size: large enough for everyone expected on site, including contractors and visitors.
• Clearly marked: signed with standard assembly point signage and shown on site maps.

Muster Procedures

1. Evacuate: on alarm, workers leave by the nearest safe route without stopping for belongings.
2. Report to the muster point: go directly to the assigned point and stay there.
3. Account for everyone: wardens or supervisors take a headcount using visitor logs, sign-in records, badge data or a mobile mustering app.
4. Report missing persons: immediately tell the incident commander or emergency services about anyone unaccounted for and their last known location. See incident command system (ICS).
5. Wait for the all clear: no one re-enters until authorized.

Muster points should be tested through regular drills, and the time taken to account for everyone should be tracked and improved. Remote and lone workers need a way to check in when they cannot reach a physical muster point.

Example of Muster Point

During a fire drill at a manufacturing site, staff gathered at the main muster point in the front parking lot. Wardens counted heads using the paper sign-in sheet, but it took more than 25 minutes to confirm that everyone was out, and two contractors who had signed in at a side gate were reported as missing.

After the drill, the site introduced a digital sign-in system that fed a live roster to wardens' phones, added an alternate muster point upwind of the solvent storage area and trained wardens on the new process. At the next drill, everyone was accounted for in under eight minutes.

Frequently Asked Questions: Muster Point

What is the difference between a muster point and an assembly point?

They mean the same thing. "Muster point" is common in oil and gas, maritime and industrial settings, while "assembly point" is widely used in offices and public buildings.

How far should a muster point be from a building?

It depends on the hazards, but it should be far enough to protect people from heat, smoke, debris and toxic releases, and clear of emergency vehicle access. Many organizations use at least 50 feet for ordinary buildings and much greater distances at high-hazard sites.

Why are headcounts important?

Headcounts tell responders whether anyone may still be inside, so they can focus search and rescue efforts and avoid unnecessary risks.
