SUPERVISORY RESPONSIBILITIES
-
Supervisors shall identify and report all job areas and locations that are or may be confined spaces.
-
Maintain and provide a list of confined spaces that are identified which shall be submitted to the Safety Organization.
-
In addition, the designated supervisors shall carry out the following tasks:
-
Classify confined spaces as "permit required," “Alternate Procedure” or "non-permit required.”
-
Identify personnel who will enter confined spaces.
-
Identify the personnel under their supervision required to wear respirators.
-
Advise personnel on routine measurement of respiratory hazards in confined spaces.
-
Provide detailed instruction and training on confined space hazards and entry procedures to those who may enter confined paces.
-
Provide instruction to personnel on the proper use of equipment required for confined space entry.
-
Maintain equipment that is used to enter confined spaces.
-
Maintain records of equipment maintenance and employee training.
-
Inform employees who may enter the permit confined space by posting danger signs or by training.
-
Issuance and cancellation of entry permits.
-
Establishment of a lockout program for their department.
-
Identify and evaluate the hazards of permit spaces before employees enter them.
-
Conduct a pre-entry briefing to inform entrants of possible hazards that may be encountered.
-
Identify the people who will enter the confined spaces.
-
Take the necessary measures to prevent entrance into prohibited permit spaces.
DUTIES OF THE “LEAD WORKER” (ENTRY SUPERVISOR)
-
Know the potential hazards during entry and work.
-
Determine if acceptable entry conditions are present at a permit space where entry is planned.
-
Terminate entry as required by the standard.
-
Verify that rescue services are readily available and the means for summoning them are operable.
-
Remove unauthorized individuals who enter or try to enter the permit space during entry and work.
-
Determine that entry and work operations remain consistent with entry permit terms and that acceptable entry conditions are maintained.
-
Determine if entry into confined space is necessary to perform work.
MINIMUM REQUIRED EQUIPMENT
-
The following minimum required equipment should be on hand:
-
Ventilation
-
Barrier and warning signs
-
Gas monitor capable of measuring concentrations of oxygen, flammable gases, hydrogen sulfide and carbon monoxide.
-
Eliminate any unsafe conditions before the access door or cover is opened.
HAZARD ASSESSMENT
-
Test the real or potential atmospheric hazards
-
Oxygen content less than 19.5% or greater than 23.5%
-
Flammable gases and vapors greater than 10% of the LEL (Lower Explosive Limit)
-
Hydrogen Sulfide concentrations greater than 10 ppm (Parts per million)
-
Carbon Monoxide concentrations greater than 35 ppm
-
Review the space for other observable serious safety and health hazards
- Mechanical
- Electrical
- Fire
- Heat stress
- Engulfment
- Entrapment hazards
- Other
-
Is there any hazardous atmosphere detected?
-
Determine and eliminate the source of the atmospheric hazards (for example: carbon monoxide from nearby truck or gas-powered generator).
-
When the atmosphere contains toxins or flammables, ventilate the space by drawing air out until the air has been changed over several times.
-
When oxygen deficient, ventilate by pushing air into the space until the air has been changed over several times.
-
Verify the hazardous atmosphere has been eliminated by testing the air.
-
From information gathered above, determine which of the following entry procedures is appropriate: Non-Permit Space - If there are neither real nor potential atmospheric hazards and no observable serious safety and health hazards, this should be certified in writing. Alternative Entry Procedures – If no observable serious safety and health hazards exist and atmospheric hazards are controlled with continuous ventilation; this should be certified in writing. Permit-Required Space - If there are any observable serious safety/health hazards in addition to potential or real atmospheric hazards, all procedure here must be followed. Authorize permit with signature. Non-Respirable Atmospheres - If hazardous atmosphere cannot be eliminated by continuous ventilation, contact the Safety Organization before continuing.

PRE-ENTRY PRECAUTIONS
-
Notify affected departments of service interruption.
-
Lock-out/tag-out all sources of energy (e.g. steam, electric, mechanical) posing a risk to workers.
-
Install blank in affected pipes where valves are not secure or seated.
-
Clean and/or purge any chemical storage vessel.
-
Wear appropriate personal protective and respiratory protection.
-
Have lights and or ladder available.
-
If coordination is needed with contractors, see Contractor Checklist.
-
Have appropriate MSDS's (Material Safety Data Sheet).
-
Determine how often air monitoring will be conducted.
