1 Confined Space Entry

2 Safety Through Teamwork “Nothing is so important that it can not be done safely.”

3 Training Outline zIntroduction zOSHA Regulations zGeneral Hazards zAtmospheric Testing zSafety Procedures zChecklists zBLD 4020 zPractical Evaluation

4 Introduction Confined space definition: zIs large enough that an employee can enter and perform assigned work zHas limited or restricted means for entry or exit zIs not designed for continuous employee occupancy

5 Introduction Examples of confined spaces: zstorage tanks zpits zsilos zvats ztunnels zsewers zshafts zexhaust ducts

6 Introduction Regulatory Requirements zOSHA- employee safety- permit confined spaces- 29 CFR zThe employer must assess the workplace to determine if hazards are present that necessitate the use of PPE

7 Permit Space Hazards Hazardous atmosphere (too little or too much oxygen, flammable or toxic air) Engulfment Danger from unexpected movement of machinery Electrocution Heat stress Becoming wedged into a narrow space and suffocating

8 Reducing Risks of Hazards zDevelop and use a written Standard Operating Procedures for confined space rescue team zConduct air monitoring and other tests to identify and evaluate hazards in each permit space zVentilate, eliminate, or control the space’s atmospheric hazards before entry into the space zLock-Out/Tag-Out ensure and place our Lock- out/ Tag out kit on were needed.

10 Preparation of Permit Space zPost signs and put up barriers to protect entrants from traffic and pedestrians zBlind or disconnect and cap all input lines so that no hazardous materials can enter the space zEmpty space of any materials that may be hazardous zVerify breathing safety by air testing

11 Safety Procedures zAuthorized entrants can enter a permit space only after it’s been tested and found safe for entry zThe assigned entrant has to know what equipment to use- and how to use it zOnce prepared, you want to get in and do the assigned task as quickly and efficiently as possible zAlert the attendant immediately if you recognize a sign or symptom of exposure to a dangerous situation

12 NFPA z7.1.4 A confined space rescue team shall be made up of a minimum of six individuals for organizations operating at the technician level, and a minimum of four individuals for organizations operating at the operations level.

13 LEVELS OF RESUCE CERTS. zAWARNESS zOPERATIONS zTECHNICIAN zWe operate at the Technician Level

14 ASSESMENT OF THE SCENE z(1) Hazards such as engulfment potential, environmental hazards (e.g., chemical, atmospheric, temperature), harmful forms of energy (e.g., electrical, mechanical, movement due to gravity, hydraulic), configuration hazards (e.g., diverging walls, entrapment, obstructions, trip/fall hazards), and so forth z(2) Risk/benefit analysis (body recovery versus rescue) z(3) Available/necessary additional resources z(4) Establishment of control zones z(5) Magnitude of the hazard and isolation procedures z(6) Effectiveness of the non-entry or qualifying entry-type rescue z(7) Overall safety of rescue operations z(8) Level of rescue response (appropriate for the type of rescue being attempted) z(9) Current and projected status of the planned response z(10) Personnel accountability

15 Site Safety Plan zA site safety plan can also provide useful information for consideration during size-up and should include the following: z(1) Rescue team notification z(2) Acceptable entry conditions for rescue z(3) Hazard identification z(4) Risk assessment of hazards z(5) Site map

16 Site Safety Plan z6) Hazard abatement (including control zones, ventilation, and lock-out/tag-out procedures) z(7) Use of buddy system (where applicable) z(8) Communications (e.g., site, rescue attendant to rescue entrant) z(9) Command post z(10) Incident management organizational chart

17 Site Safety Plan z(11) Standard operating guidelines z(12) Safe work practices z(13) Medical assistance z(14) Pre-entry safety briefings z(15) Pre- and post-entry physicals (if indicated)

18 CHECKLIST

20 CONFINED SPACE ENTRY CHECK LIST Rescue Sector zCONFINED SPACE IS 1. LARGE ENOUGH TO ENTER. z 2. LIMITED OR RESTRICTED OPENINGS. z 3. NOT DESIGNED FOR COMTINUOUS z WORKER OCCUPANCY. zCALL FOR CONFINED SPACE RESCUE TEAM & EQUIPMENT! zCONTACT ATTENDANT (WHO CALLED) YES NO zREAD ENTRY PERMIT YES NO zREAD MSDS YES NO zWHAT KIND OF WORK IS BEING DONE ? zWHAT ARE THE HAZARDS ? zIS THIS A RESCUE BODY RECOVERY zHOW MANY VICTIMS ? zCAN SELF RESCUE BE COMPLETED YES NO zSAFETY OFFICER CHECKED ALL z LOCK OUT / TAG OUT YES NO z MECHANICAL EQUIPMENT BLOCKED OR z DISENGAGED YES NO z LINES UNDER PRESSURE BEEN BLANKED z & BLED YES NO z IF NO THEN ACCOMPLISH

21 CHECK LIST Rescue Sector zOXYGEN LEVEL BETWEEN 19.5% % YES NO z IF NO USE PROPER PPE z READINGS z TOP % MIDDLE % BOTTOM % z zLOWER EXPLOSIVE LIMITS (LEL) < 10% YES NO z IF NO USE PROPER PPE z READINGS z TOP % MIDDLE % BOTTOM % z DO NOT ENTER IF LEL IS > 10% UNTIL YOU CAN LOWER IT z IF OXYGEN IS NOT NORMAL THAN THE LEL WILL BE OFF zTOXIC HAZARD < PERMISSIBLE EXPOSURE LIMIT z (PEL) YES NO z IF NO USE PROPER PPE z READINGS z TOP % MIDDLE % BOTTOM % zDO RESCUERS NEED SPECIAL PROTECTIVE CLOTHING YES NO z IF YES WHAT ? zDOES THE AREA NEED VENTILATION YES NO zCONTINUOUS ATMOSPHERE MONITORING YES NO zIS THE HEIGHT > 5’ YES NO z IF YES HARNESS & LIFTING DEVICE REQUIRED zWILL RESCUERS & VICTIM NEED DECON YES NO zWILL VICTIM NEED FIRST AID, CPR, z IMMOBILIZATION, LIFTING DEVICE YES NO zWERE RESCUERS BRIEFED ON HAZARDS, EXPOSURE z SYMPTOMS, # VICTIMS, & EVACUATION WARNINGS YES NO

22 Summary zWhat is a confined space zPermit required spaces zChecklists zHow we are going to do it zAny questions? zPractical stations zPractical Eval.
