Permit-Required Confined Spaces

29 CFR 1910.146


Why comply

Why Comply????

  • Confined space entry is a leading cause of occupational fatalities in this country


Definition of a confined space

Definition of a Confined Space

  • Limited means of egress

  • Can be bodily entered

  • Not designed for continuous occupancy


Definition of permit required confined spaces

Definition of Permit-RequiredConfined Spaces

  • Contains or has potential to contain a hazardous atmosphere

  • Contains the potential for engulfment

  • Internal configuration that can trap or asphyxiate entrant

  • Any other serious safety or health hazards


Typical permit required spaces

Typical Permit-Required Spaces

  • Chemical Storage

    Tanks and Vessels

  • Pits

  • Waste Water

    Lift Sumps

  • Underground

    Sewage Tunnels

  • Industrial Steam Boilers


Typical non permit required spaces

Typical Non-Permit-Required Spaces

  • Utility closets

  • Below-grade trenches

  • Storage vaults

  • Utility subbasements


Potential confined space hazards

Potential Confined Space Hazards

  • Engulfment

  • Oxygen deficiency (19.5% or less)

  • Oxygen enrichment (23.5% or higher)

  • Flammable gases or vapors

  • Combustible dusts

  • Toxic substances

  • IDLH atmospheres


Atmospheric testing

Atmospheric Testing

  • Hazards must be tested in this order:

    • Oxygen content

    • Combustibility/flammability

    • Toxic atmospheres

  • Entrants must be allowed to observe monitoring


Reasons for space ventilation

Reasons for Space Ventilation

  • Maintain oxygen levels above 19.5%

  • Maintain toxic gases and vapors at acceptable levels


Types of personal protective equipment

Types of Personal Protective Equipment

  • Harnesses

  • Retrieval lines

  • Chemical protective clothing

  • Welding apron/sleeves

  • Respirators

  • Gloves

  • Safety glasses


Company s responsibilities

Company’s Responsibilities

  • Formulate and manage the confined spaces program

  • Maintain a confined space inventory

  • Maintain a list of “Authorized Personnel”

  • Maintain copies of confined space permits

  • Direct the confined space training program

  • Maintain rescue equipment

  • Coordinate contractor activities


Authorized attendant responsibilities

Authorized Attendant Responsibilities

  • Know the hazards that may be faced

    during entry.

  • Be knowledgeable in the use and

    care of applicable atmosphere sampling

    equipment.

  • Conduct all atmosphere tests/sampling

    specified by the permit and render the

    atmosphere safe before entry can be made.

  • Be aware of possible behavioral effects of hazard exposure in Authorized Entrants.

  • Continuously maintain an accurate count of Authorized Entrants in the confined space.

Authorized attendant responsibilities cont

Authorized Attendant Responsibilities (cont.)

  • Remain outside the permit space during entry operations until relieved by another Authorized Attendant.

  • Communicate with Authorized Entrants as necessary to adequately monitor their status.

  • Monitor activities inside and outside the confined space and order Authorized Entrants to evacuate when necessary.

  • Summon rescue services if needed (by use of portable radio or phone).

  • Keep unauthorized persons out of the permit space.

  • Do not perform any duties that might interfere with monitoring duties.

Document No. EHSL-6.2.2-00.001D Rev. R1 Rev. Date: 01/30/09


Authorized entrant responsibilities

Authorized Entrant Responsibilities

  • Know the hazards that may be faced during entry.

  • Recognize signs and symptoms of exposure.

  • Properly use entry equipment

  • Communicate with the Authorized Attendant as necessary to enable the Attendant to monitor Authorized Entrant status and to enable the Attendant to alert Entrants of the need to evacuate the space.

  • Alert the Authorized Attendant whenever warning signs or symptoms of exposure to a dangerous situation are recognized or a prohibited condition is detected.

  • Exit from the space as quickly as possible whenever:

    • An order to evacuate is given by the Attendant or the Entry Supervisor.

    • Any warning signs or symptoms of exposure to a dangerous situation are recognized.

    • A prohibited condition is detected.

    • An evacuation alarm is activated


Confined space supervisor responsibilities

Confined Space Supervisor Responsibilities

  • Know the hazards that may be faced during entry.

  • Verify by checking that the appropriate entries have been made on the permit, that all tests specified by the permit have been conducted, and that all procedures and equipment are in place before endorsing the permit and allowing entry to begin.

  • Terminate entry and cancel the permit as required.

  • Verify rescue services are available and that the means for summoning them are operable.

  • Remove unauthorized individuals who enter or attempt to enter the permit space during operations.

  • See that entry operations remain consistent with the permit

  • Ultimately, the Confined Space Supervisor is responsible for all confined space entry activities.


Rescuer responsibilities

Rescuer Responsibilities

  • Understand the hazards of the space

  • Be certified in emergency first aid and CPR

  • Understand appropriate entry procedures

  • Know how to use rescue equipment

  • Practice confined space rescues at least annually
