Why Comply????
Confined space entry is a leading cause of occupational fatalities in this country

Not designed for continuous occupancy

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

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
![Page 8: Confined Space Training](https://reader036.vdocuments.us/reader036/viewer/2022062320/55cf9966550346d0339d3464/html5/thumbnails/8.jpg)
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
Maintain oxygen levels above 19.5%
Maintain toxic gases and vapors at acceptable levels

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.)
• 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.

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
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
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
