The job hazard analysis
PPE required: Hard hat, Safety glasses, Gloves, Safety boots, Fall arrest harness
1. Identify and classify the space
What could go wrong
Entering without knowing the hazards
How we control it
Decide whether the space needs a permit under your program and local rules. Mark and sign the space.
2. Isolate and test the air
What could go wrong
Toxic, flammable, or oxygen-poor air; energy sources
How we control it
Lock out energy and block pipes. Test the air for oxygen, flammable gas, and toxic gas before entry and as the program says.
3. Ventilate and set up rescue
What could go wrong
Air changing during work; no way to get help
How we control it
Provide ventilation. Assign an attendant outside who can call for rescue but never enters. Have rescue equipment ready.
4. Enter and work
What could go wrong
Fumes from the work; loss of contact
How we control it
Keep communication open. Monitor the air. Leave right away on any alarm.
5. Close out
What could go wrong
Leaving people or tools inside
How we control it
Count people and tools out. Cancel the permit and secure the space.
- Most confined space deaths include would-be rescuers. Never enter to rescue without a plan and the right equipment.
When to use it
Use it with your written confined space program. Many spaces need a permit, testing, and a rescue plan before anyone enters.
Review it with the crew before the work starts, change anything that doesn't match how you'll do the job, and update it when the method, the equipment, or the site changes.
