CONFINED SPACE ENTRY :CONFINED SPACE ENTRY
CONFINED SPACE STATISTICS :2 CONFINED SPACE STATISTICS 65% of all confined space fatalities are due to hazardous atmosphere
In 139 deaths, there were no detectors nor ventilation
One-third of all deaths were supervisors
60% were rescuers
25% of spaces were toxic before entry
IDENTIFICATION OF CONFINED SPACES :3 IDENTIFICATION OF CONFINED SPACES Has limited opening(s) for entry and exit
An actual or potential hazardous atmosphere exists
Space not designed for continuous worker occupancy
Entry is determined as soon as plane of opening is broken
OSHA REQUIREMENTS :4 OSHA REQUIREMENTS Identify All Confined Spaces
Treat All Confined Spaces As Hazardous Until Proven Otherwise
If Possible, Identify All Hazards In Confined Space Before Entry
Respond Appropriately To Hazards Before Entry
EXAMPLES OF CONFINED SPACES ON CAMPUSES :5 EXAMPLES OF CONFINED SPACES ON CAMPUSES Elevator shafts
Boilers
Pits
Air handling units Small mechanical rooms
Switch closets
Basements
POTENTIAL HAZARDS :6 POTENTIAL HAZARDS Hazardous atmospheres
Toxic gases
Flammable gases
Oxygen rich or deficient
Physical hazards
Slips, trips, or falls
Electrical
Gravity
Chemical contact hazards
Biological hazards
HAZARDOUS ATMOSPHERES :7 HAZARDOUS ATMOSPHERES Oxygen rich (greater than 23.5%)
Oxygen deficient (less than 19.5%)
Toxic
Flammable
Corrosive
Other gas displacement
ATMOSPHERIC TESTING :8 ATMOSPHERIC TESTING Assume all confined space requires an entry permit until testing is done. Test types are:
1. Evaluative
2. Verification
3. Duration
4. Stratified
5. Periodic and continuous
ORDER OF TESTING :9 ORDER OF TESTING First – Verify oxygen presence and amounts
Second - Flammables
Third – Toxics
Hydrogen Sulfide
Carbon Monoxide
PHYSICAL HAZARDS :10 PHYSICAL HAZARDS Potential for engulfing
Hot work
Sides/walls so configured that exit is prevented (sloping, covered, high, etc.)
Airborne dusts or other substances
Electrical hazards
Poor housekeeping
CONFINED SPACE PROGRAM REQUIREMENTS :11 CONFINED SPACE PROGRAM REQUIREMENTS Written program
Hazard identification procedures
Hazard abatement and control
Permit system
Employee training
Proper equipment
Adequate rescue plan
Procedure for working with contractors
CONFINED SPACE ENTRY :12 CONFINED SPACE ENTRY Survey workplace for confined space
Test confined space to determine if permit or non-permit confined space
Isolate confined space from other employees and non-employees
Perform all activities according to written plan
NON-PERMIT ENTRY :13 NON-PERMIT ENTRY No hazards – Or:
Ventilate actual or potential hazards
Correct hazard source
Written supervisor approval for re-entry after hazard correction
PERMIT REQUIRED ENTRYWritten Plan (Permit) Required :14 PERMIT REQUIRED ENTRYWritten Plan (Permit) Required Isolate internal and external area
Hazard identification and evaluation
Prevention of unauthorized entry
Develop and implement safe entry process
Conditions (must include continuous testing and safe work conditions)
Identify any needed equipment
PERMIT REQUIRED ENTRYWritten Plan (Permit) Required :15 PERMIT REQUIRED ENTRYWritten Plan (Permit) Required Describe barricades/barriers needed to protect pedestrians and others
Describe rescue and emergency procedures
Describe procedure for preparation, issuing, and cancellation of the confined space entry permit
Describe coordinated entry operations
Review and revise at least annually
EQUIPMENT REQUIRED :16 EQUIPMENT REQUIRED Testing and monitoring
Ventilating
Communications
Lighting, barriers, and shields
Safe ingress and egress
Rescue and emergency
PPE
Specific equipment needed
EXTERNAL CONTRACTOR :17 EXTERNAL CONTRACTOR Must comply with college’s rules
Entry supervisor to share information
Entry supervisor must coordinate entry with contractor
Contractor to inform supervisor of any hazard confronted or created in permitted space
WRITTEN PROGRAM :18 WRITTEN PROGRAM Unauthorized entry measures
How to identify and evaluate permit space hazards
Means, procedures, and practices needed for safe entry
Rescue and emergency operations
Coordinated entry
Review and revise at least annually
CONFINED SPACE PERMIT :19 CONFINED SPACE PERMIT Specific space to be entered
Purpose of entry
Date and length of time of entry
Authorized entrant, authorized attendant, and entry supervisor
Actual hazards and potential hazards
CONFINED SPACE PERMIT :20 CONFINED SPACE PERMIT Measures used to isolate space
Communications procedures
Equipment needed
Acceptable entry conditions
Initial and periodic test results
Rescue and emergency means
Any other permits, e.g., hot work
