Confined Space Awareness
Confined spaces kill rescuers — over half of confined-space deaths are people who went in after the first victim. That statistic is the whole talk. A free talk from Blue Crane Works in Hamilton, Ontario, with a printable sign-in sheet.
How to run it
Read it through once, then talk it — don't recite it. Five minutes at the start of the shift, crew standing where the work happens. Ontario's Occupational Health and Safety Act requires every employer to provide information, instruction and supervision to protect workers (s. 25(2)(a)). A talk like this, led by a supervisor or someone they trust, is one way to do it, and the sign-in sheet is what proves it happened.
Talk through these points
- Know what counts: tanks, pits, vaults, crawlspaces — not designed for people, limited ways in and out, and able to hold a bad atmosphere.
- The air lies. Oxygen-deficient or toxic atmospheres have no look and often no smell — testing is the only way to know, before entry and continuously.
- No assessment, no entry. If the space hasn't been assessed and the entry planned, the job hasn't started yet.
- An attendant stays outside, in contact, with one job: nobody else goes in, and rescue gets called properly.
- If someone goes down inside: DO NOT follow them in. That instinct is the killer. Call the rescue plan.
- Ventilation, isolation of lines feeding the space, and lockout of what moves inside — the setup IS the safety.
Ask the crew
- What on our sites actually qualifies as a confined space that we treat casually?
- If someone dropped in a vault right now, what would each of us actually do?
- Who's trained on the gas monitor — and when was it calibrated?
The answers are the real talk. If a question lands on a live hazard, write it down and assign it a name and a date.
