Scout's Toolbox Talks

Before anyone enters a confined space, the air must be made safe — and kept that way throughout the work.

Why It Matters:

Confined spaces often lack natural airflow, which allows dangerous gases to accumulate. Ventilation is your first line of defense to ensure breathable air and prevent buildup of flammable or toxic fumes.

Key Points:

• Use mechanical ventilation — fans, blowers, or air movers — to circulate fresh air.
• Start ventilating before entry and continue while work is ongoing.
• Position the intake away from engine exhaust or chemical sources to avoid pulling in contaminants.
• Ensure airflow reaches the entire space, especially corners and low areas where gases can collect.
• Re-test the atmosphere after ventilating and periodically during work.
• If hot work (e.g., welding) is involved, increase ventilation to remove fumes and heat.

✅ No airflow = no entry.

Ask the Crew:

• Are we ventilating the space right now?
• Have we tested the air before AND after ventilation?
