Confined Space Defined (AFOSH STD 91 -25) 4 A Confined Space: – Is large enough and so configured that an employee can bodily enter and perform work – Has limited or restricted means for entry or exit (for example, tanks, vessels, silos, storage bins, hoppers, vaults, and pits are spaces that may have limited means of entry) – Is not designed for continuous occupancy

Confined Space Program Goal –Simply Stated, our goal is to not experience a single injury or death

Identifying, Evaluating and Classifying Confined Space

a. The Functional Manager or Commander, in coordination with personnel on the CSPT, will; Identify, Evaluate, Classify each Confined Space 1. Identify; Locate your Confined Spaces and ensure you are responsible for that facility. 2. Evaluate; Your Confined Spaces and fill out a survey form for each Confined Space.

3. Classify; Confined Spaces are classified on the basis of measurements of; a. Space Characteristics (potential physical hazards) b. Oxygen content c. Flammability d. Toxicity * Bio-Environmental, Fire Department and Wing Safety will be present during classification

4 If the workplace contains permit spaces: – All personnel are informed of the existence, location, and the danger – Note: A sign reading DANGER -- PERMITREQUIRED CONFINED SPACE, DO NOT ENTER or some similar language would satisfy the requirement

4 If the employees will not enter permit spaces: – Preventative measure will be taken to prevent entry into permit spaces 4 If the employee will enter permit spaces the employer will: – Implement a written permit program

4 Before removing cover: – Eliminate any condition making it unsafe to remove an entrance cover 4 The opening shall be promptly guarded by: – Railing – Temporary cover – Temporary barrier

4 Before entry into the space: – Internal atmosphere shall be tested • Using calibrated direct-reading instrument • By a qualified person for the following conditions in the order given – Oxygen content – Flammable content – Potential toxic air contaminant 4 There shall be no hazardous atmosphere within the space whenever any employee is inside the space

Confined Space Entry Ventilation

4 Continuous forced air ventilation shall be used as follows: – An employee may not enter the space until the forced air ventilation has eliminated any hazardous atmosphere – The forced air ventilation shall be directed as to ventilate the immediate area where an employee is or will be present and shall continue until all employees have left the space – The air supply for the forced air ventilation shall be from a clean source and may not increase the hazards in the space

4 The atmosphere within the space shall be periodically tested 4 If a hazardous atmosphere is detected during entry: – Each employee shall leave the space immediately – The space shall be evaluated to determine how the hazardous atmosphere developed – Implement procedures to protect employees from any hazards before any subsequent entries takes place

– Verify the space is safe for entry through a written certification that contains: – Date – Location of space – Signature of person providing the certification 4 The certification shall be made before entry and made available to each employee entering the space

4 When there are changes in the use or configuration on a non-permit confined space the space will be reevaluate and reclassified as necessary 4 A space classified as a permit required confined space may be reclassified as a non-permit confined space under the following conditions: – If the permit space poses no actual or potential atmospheric hazards – If all hazards within the space are eliminated without entry into the space

– If testing and inspection during entry demonstrate that the hazards have been eliminated • Note: Control of atmospheric hazards through forced air ventilation does not constitute elimination of the hazard – The employer shall document the basis for determining that all hazards have been eliminated through a certification that contains a date, location of space and signature of person making the determination 4 If hazards arise within a permit space each employee in the space will exit

PERMIT SYSTEM

4 The employer, through the permit system shall: – Complete and document all steps necessary for entry – Require initials or signature of persons completing the – – steps Post permit at entry and make the permit available to all authorized entrants Ensure permit is signed by supervisor Duration of permit may not exceed time required to complete assigned task Permit must be canceled if a prohibited condition arises, or work has been completed

– The employer shall retain each canceled entry permit for 1 year. Any problems encountered during an entry operation shall be noted on the pertinent permit, so that appropriate revisions to the program can be made

ENTRY PERMIT

4 Permit required when space • Contains or has a potential to contain a hazardous atmosphere • Contains a material that can engulf an entrant • Internal configuration of the space that an entrant could be trapped or asphyxiated • Contains any other recognized serious safety or health hazards

ENTRY PERMIT AF FM 1024 4 Identifies: – Space to be entered – Purpose of entry – Date and authorized duration of the entry permit – Authorized entrants within the permit space by name – Entry supervisor, by name with a space for the signature – Hazards of the permit space – Measures used to isolate the permit space and to eliminate or control permit space hazards before entry

– – – Acceptable entry conditions Test results with signature or initials of tester(s) Rescue services and the means for summoning them Communication procedures and equipment Equipment, such as PPE, testing, communications, alarm systems and rescue – Any other information needed to ensure safe entry – Any additional permits (such as for hot work)

– No Permit required when space is • Considered Non-Hazardous • Entries into these spaces do not require an entry permit • “Buddy System” • The process or the operation being conducted within the confined space may change the space to a Permit Required Confined Space • Validate that hazardous conditions do not exist before entering the space

MASTER ENTRY PERMIT (MEP)

1. The MEP is nothing more than a master permit that identifies all your routinely entered confined spaces. You have all of these areas documented on your MEP.

2. The MEP, a part of the overall written confined spaces program, will serve as an approval for recurring entries having the same conditions and entry requirements when signed by representatives of SEG, CEF and BEE.

3. The MEP allows functional managers and commanders to designate entry supervisors to issue Field Entry Permits. Your MEP must be reviewed by supervisor and re-certified each year and signed by; a. Bio-environmental Engineering (BE) b. Fire Department (CEF) c. Group Safety (SEG)

4. Once your MEP is approved and certified you are authorized to issue Field Entry Permits for entry into areas specifically identified on the MEP 5. To ensure your MEP contains all required areas, refer to AFOSH STD 91 -25 Pg 7, para 2. 10. 4 dated Feb 1998

TRAINING REQUIREMENTS
