Not every task can simply “just start”
Work at height, confined space entry, electrical work, hot work — these activities carry enough potential for severe harm that you can’t just show up and begin. A formal authorization is required first, confirming the conditions are actually safe.
What that authorization actually verifies
- Whether the specific hazard for that activity was truly assessed.
- Whether whatever needed to be isolated or locked out already is.
- For confined spaces: whether the air inside is actually safe to breathe.
- Whether someone is ready to respond if something goes wrong.
Two high-risk activities, same place, same time
Picture welding happening near a confined space entry point — the hazard from one activity can feed directly into the hazard of the other. That’s why, when two things like that overlap, someone needs to cross-check both before clearing either one.
Finished? Close it out properly
Wrapping up the task and walking away isn’t enough. The area needs to be formally “deactivated” — confirming everything is safe again, with no hidden hazard waiting for the next unsuspecting person.
This isn’t excessive red tape
Every one of these requirements exists because, somewhere, someone already got hurt — or worse — from skipping that step. A work permit is a hard lesson turned into prevention.
