Key Hazards
- Poor air quality from inadequate ventilation
- Contaminated air drawn into the confined space
- Ventilation hoses blocked, kinked, or disconnected
- Workers relying on ventilation without atmospheric testing
- Trip hazards from hoses, cords, and equipment
- Ventilation stopped or reduced during entry
2–3 Minute Talk Script
Ventilation equipment is an important control for many confined space entries, but it only helps when it is set up, tested, and monitored correctly. A blower running near the space does not automatically make the atmosphere safe.
Atmospheric testing should be performed according to procedure before entry and during the work as required. Ventilation should support the entry plan, not replace testing or monitoring.
The air intake location matters. Blowers should draw clean air from a safe area, away from vehicle exhaust, generators, chemical vapors, sewer gases, fuel fumes, or other contaminants.
Ventilation ducts or hoses should be positioned to move air where it is needed inside the space. Poor placement can leave pockets of hazardous air even when air is flowing.
Hoses should be protected from kinks, crushing, disconnection, or blockage. A hose that is stepped on, driven over, folded, or pulled loose can reduce airflow without workers noticing immediately.
Ventilation equipment, cords, and hoses should be routed to avoid trip hazards and to keep access and rescue paths clear. Entry points should not become cluttered with equipment.
Workers should know what to do if ventilation stops. A failed blower, power loss, disconnected hose, or blocked intake can change the atmosphere quickly.
Confined space ventilation safety requires verification. Confirm clean air, proper airflow, safe hose routing, continuous monitoring, and a response plan before relying on ventilation as a control.
Safety Reminders
- Test the atmosphere before entry and as required during work.
- Use ventilation equipment according to the entry plan.
- Place blower intakes in clean air.
- Position ducts or hoses to ventilate the needed area.
- Protect hoses from kinks, crushing, and disconnection.
- Keep cords and hoses from blocking access or rescue paths.
- Stop work if ventilation fails or air quality changes.
Ask the Crew
- Has the atmosphere been tested before entry?
- Is the blower drawing clean air?
- Is airflow reaching the area where workers will be?
- Could hoses or cords be crushed, kinked, or disconnected?
- What is the plan if ventilation stops during entry?
