4Introduction Confined space definition: Is large enough that an employee can enter and perform assigned workHas limited or restricted means for entry or exitIs not designed for continuous employee occupancy
6Introduction Regulatory Requirements OSHA- employee safety- permit confined spaces- 29 CFRThe employer must assess the workplace to determine if hazards are present that necessitate the use of PPE
7Permit Space HazardsHazardous atmosphere (too little or too much oxygen, flammable or toxic air)EngulfmentDanger from unexpected movement of machineryElectrocutionHeat stressBecoming wedged into a narrow space and suffocating
8Reducing Risks of Hazards Develop and use a written Standard Operating Procedures for confined space rescue teamConduct air monitoring and other tests to identify and evaluate hazards in each permit spaceVentilate, eliminate, or control the space’s atmospheric hazards before entry into the spaceLock-Out/Tag-Out ensure and place our Lock-out/ Tag out kit on were needed.
10Preparation of Permit Space Post signs and put up barriers to protect entrants from traffic and pedestriansBlind or disconnect and cap all input lines so that no hazardous materials can enter the spaceEmpty space of any materials that may be hazardousVerify breathing safety by air testing
11Safety ProceduresAuthorized entrants can enter a permit space only after it’s been tested and found safe for entryThe assigned entrant has to know what equipment to use- and how to use itOnce prepared, you want to get in and do the assigned task as quickly and efficiently as possibleAlert the attendant immediately if you recognize a sign or symptom of exposure to a dangerous situation
12NFPA7.1.4 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.
13LEVELS OF RESUCE CERTS. AWARNESS OPERATIONS TECHNICIAN We operate at the Technician Level
14ASSESMENT OF THE SCENE(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 (2) Risk/benefit analysis (body recovery versus rescue) (3) Available/necessary additional resources (4) Establishment of control zones (5) Magnitude of the hazard and isolation procedures (6) Effectiveness of the non-entry or qualifying entry-type rescue (7) Overall safety of rescue operations (8) Level of rescue response (appropriate for the type of rescue being attempted) (9) Current and projected status of the planned response (10) Personnel accountability
15Site Safety PlanA site safety plan can also provide useful information for consideration during size-up and should include the following: (1) Rescue team notification (2) Acceptable entry conditions for rescue (3) Hazard identification (4) Risk assessment of hazards (5) Site map
16Site Safety Plan6) Hazard abatement (including control zones, ventilation, and lock-out/tag-out procedures) (7) Use of buddy system (where applicable) (8) Communications (e.g., site, rescue attendant to rescue entrant) (9) Command post (10) Incident management organizational chart
17Site Safety Plan (11) Standard operating guidelines (12) Safe work practices (13) Medical assistance (14) Pre-entry safety briefings (15) Pre- and post-entry physicals (if indicated)
