OP 60.16 Confined Space Entry Program
A confined space is an enclosed area described as follows:
- Has limited or restricted means of entry or exit;
- Is large enough for a person to enter to perform tasks;
- Is not designed or configured for continuous occupancy;
- Has the potential for a significant hazard to be present.
Hazards in a confined space often include harmful dust or gases, asphyxiation, submersion in liquids or free-flowing granular solids (for example, grain bins), electrocution, or entrapment.
Confined space accidents are of particular concern in occupational safety and health due to the hazards that they pose to the victim and subsequently to a rescue team.
Confined space training outlines the skills and protocols for safe entry to confined spaces, and includes precautions such as:
Locking and tagging out electrical equipment,
Blocking or blanking piping,
Securing kinetic energy stored in equipment.
Testing confined space atmosphere for toxic gases, flammable gases, and oxygen content.
The need for forced ventilation,
Observation of workers in the space, and
A predetermined rescue plan with appropriate safety harnesses and other rescue equipment standing by
