Study Notes
Confined Space Entry: Key Facts and Procedures
- Confined space is an enclosed or partially enclosed area not designed for continuous human occupancy.
- Confined spaces have limited means of entry or exit, making first aid, evacuation, and rescue difficult.
- Workers must be protected from dangerous substances discharged from pipes leading to confined spaces.
- Examples of confined spaces include manholes, sewers, storage tanks, tunnels, and cargo holds in ships.
- Confined space entry requires a written program with assigned responsibilities and hazard assessments.
- A confined space entry permit must be completed and signed by a supervisor before entry.
- Lockout and isolation procedures must be followed to control adjacent piping with harmful substances.
- Pre-entry testing and inspection are required to verify the effectiveness of precautions and safety.
- Cleaning, purging, venting, or inerting may be necessary to ensure a safe atmosphere in the confined space.
- Ventilation is necessary to maintain safe air levels in the confined space, either through natural or mechanical means.
- A standby person must monitor the activities and well-being of workers in the confined space.
- Personal protective equipment (PPE) and lifelines/harnesses must be provided for worker safety.
