Why?

  • Why do we have a confined space standard?
    • 122 confined space accidents each year lead to 173 fatalities
  • 60% of the fatalities occurred during rescue attempts
slide6

Why? (continued)

    • Intended to protect workers from
    • toxic, flammable, explosive, or asphyxiating atmospheres
    • possible engulfment
    • any otherrecognized serious hazard (example - hazardous energy)
  • The standard focuses on areas with immediate health or safety risks, denoting them as “Permit Required Confined Space”

federal register jan 14 1993 p 4477
Federal Register Jan 14, 1993 (p. 4477)

“While OSHA is concerned that spaces that are too small for complete bodily entry may pose hazards for employees, the Agency did not intend to cover such spaces under the permit space standard.”

federal register nov 4 1994 p 55208
Federal Register Nov. 4, 1994 (p. 55208)

“Limited - when an employee would be forced to enter or exit in a posture that might slow self-rescue or make rescue more difficult.”

Standard Safety Requirements for Confined Spaces (ANSI Z117.1-1995)

“Restricted entry and exit means physical impediment of the body, e.g., use of the hands or a contortion of the body to enter into or exit from the confined space”.

federal register nov 4 1994 p 552081
Federal Register Nov. 4, 1994 (p. 55208)

“For example, even if the door or portal of a space is of sufficient size, obstructions could make entry into or exit from the space difficult. The Agency intended that spaces which otherwise meet the definition of confined spaces, and which have obstructed entry or exits even though the portal is a standard size doorway, be classified as confined spaces.”

questions to ask
Questions to Ask
  • Does the person have to use their hands to enter or exit the space?
  • Is the person in an awkward posture when entering or exiting the space?
  • Is a person’s entry into or exit from the space slowed down or impeded by physical obstructions (such as pipes, ductwork, walls, holes in the floor, flanges, etc.)?
  • Would an employee be forced to enter or exit in a posture that might slow self-rescue or make rescue more difficult?
federal register jan 14 1993 p 4478
Federal Register Jan 14, 1993 (p. 4478)
  • OSHA believes that the final rule’s definition properly places the focus on the design of the space, which is thekeyto whether a human can occupy the space under normal operating conditions.
slide32

Dangerous Combinations

  • Presence of all three confined space characteristics can complicate the situation.
  • Working in and around the space.
  • Rescue operations during emergencies.
  • Worsened conditions due to work activities:
    • Welding and cutting, use of bonding agents
    • Cleaning with solvents, use of other chemicals
    • Use of gas-powered equipment
slide33

Permit Required Confined Space

  • Contains or has a potential to contain a hazardous atmosphere;
  • Contains a material that has the potential for engulfing an entrant;
  • Has an internal configuration such that an entrant could be trapped or asphyxiated by an inwardly converging walls or by a floor which slopes downward and tapers to a smaller cross section; or
  • Contains any other recognized serious safety or health hazard.

    • date
    • location
    • signature

NOTE: The above certificate must be made available to entrant to review.

entry without permit continued2
Entry Without Permit (continued)

If you meet the conditions stated in Section (C)(5)(I) of the OSHA standard, you may use the procedures specified in Section (C)(5)(ii) of the standard.
