Confined Space Awareness

Key Hazards

• Oxygen-deficient or toxic atmospheres
• Limited entry and exit points
• Engulfment or mechanical hazards

2–3 Minute Talk Script

Confined space awareness is critical for utility workers, construction crews, and industrial teams who enter tanks, vaults, pits, or other restricted spaces. Confined spaces can contain oxygen-deficient air or toxic gases that are not detectable without proper testing. Workers must approach every confined space with caution.

Entry operations require atmospheric testing, ventilation, proper PPE, and communication with attendants. Hazards inside confined spaces can develop quickly, and workers may not be able to exit on their own. Never rely on the assumption that the space was safe last time.

Different industries encounter confined spaces in different ways. Wastewater crews enter lift stations or wet wells, construction workers may work inside manholes or trenches, and industrial teams may access silos, mixers, or tanks. Each type of space presents unique hazards.

No worker should enter a confined space without full authorization, training, and the proper equipment. Communication failures or bypassing testing procedures are major contributors to confined space incidents. Teams should consistently discuss entry procedures and rescue plans.

Safety Reminders

• Test the atmosphere before every entry.
• Ensure proper ventilation is in place.
• Maintain communication with attendants.
• Never enter a confined space without authorization.

Ask the Crew

• Which confined spaces exist on today’s job?
• Do we have the proper entry permits and monitoring equipment?
