Transcript

  • 1. Confined Spaces Awareness Training Course A1 Training & Safety 2013
  • 2. Confined Spaces Course objective   To provide awareness training for confined space hazards The safe systems of work used in confined spaces. A1 Training & Safety 2013
  • 3. THE CONFINED SPACE REGULATIONS Regulation 4 states “no person at work shall enter a confined space to carry out work for any purpose unless it is not reasonably practicable to achieve that purpose without such entry” Regulation 5 states “Without prejudice to regulation 4 of these Regulations, no person at work shall enter or carry out work in a confined space unless there have been prepared in respect of that confined space suitable and sufficient arrangements for the rescue of persons in the event of an emergency, whether or not arising out of a specified risk ” A1 Training & Safety 2013
  • 4. CONFINED SPACE KEY DUTIES 1. avoid entry to confined spaces, e.g. by doing the work from outside; 2. if entry to a confined space is unavoidable, follow a safe system of work; and 3. put in place adequate emergency arrangements before the work starts. A1 Training & Safety 2013
  • 5. WHAT IS A CONFINED SPACE? A space that: • Is large enough and so configured that an employee can enter bodily and perform work; • Has limited or restricted means of entry or exit; • Is not designed for continuous human occupancy. A1 Training & Safety 2013
  • 6. Confined Spaces Examples of Confined spaces:  Open topped chambers  Trenches  Ductwork  Unventilated or poorly ventilated rooms  Void spaces A1 Training & Safety 2013
  • 7. Confined Spaces Main Hazards:  Flammable substances  Oxygen enrichment / deficiency  Toxic gas, fume or vapour Hazards effects:   Serious injury from fire or explosion Loss of consciousness or asphyxiation from dangerous fumes etc. A1 Training & Safety 2013
  • 8. Confined Spaces Oxygen:  We need 19-23% oxygen to breathe  Oxygen deficiency can be caused by oxidation, combustion or bacterial growth or by displacement by another gas, e.g. argon.  Oxygen enrichment can be caused by leaks in oxygen lines or cylinders. A1 Training & Safety 2013
  • 9. Confined Spaces Effects of oxygen concentration: 100% Brain Damage 19-23% Normal, safe levels 16% Increase heart-rate/breathing drowsiness and nausea 12% Unconsciousness 6% DEATH ! A1 Training & Safety 2013
  • 10. Confined Spaces Oxygen deficiency symptoms:       Headaches Difficulty in focusing Co-ordination difficulties Dizziness Fainting Falling down / tripping A1 Training & Safety 2013
  • 11. Confined Spaces Bottled Gases:  Never use bottled gases in confined spaces  May not have stenching agent added A1 Training & Safety 2013
  • 12. Confined Spaces Argon:      Main shielding/Purging gas on site Argon is not visible Argon is odourless (not stenched) Argon is tasteless Argon is heavier than air A1 Training & Safety 2013
  • 13. Confined Spaces Nitrogen  Nitrogen comprises 78% of the air we breathe.  Nitrogen Is an inert gas  Slightly lighter than air 0.95 (air =1)  Nitrogen is used in large quantities to purge voids etc.  If insufficient oxygen is present, high nitrogen concentrations cause asphyxiation and death in seconds. A1 Training & Safety 2013
  • 14. Confined Spaces Before a space is entered:         A safe system of work must be in place. A competent person MUST have atmosphere tested the area. Read and understand the risk assessment. Obtain and use the correct PPE. Supervisor informed. SAM and extraction in place. Each person must wear a PAM in all circumstances. Do not enter alone ! FOR ANY REASON. A1 Training & Safety 2013
  • 15. Confined Spaces Typical Entry Certificates: HOT WORK CLEAN & PAINT COLD WORK A1 Training & Safety 2013
  • 16. Confined spaces Continuation Certificate: Entry certificates  Oxygen levels are checked every 14 hrs or less for all types of work  Contact Confined space team after 14 hrs if access required Before entering check date and time are within 14 hours A1 Training & Safety 2013
  • 17. Confined Spaces Monitoring:  Air checks every 14 hours by confined spaces team.  SAM’s in all confined spaces monitoring oxygen content. A1 Training & Safety 2013
  • 18. Confined Spaces Ventilation:  Minimum One extraction hose per tank to vent  Pipe identified by “Tank Extraction” every 1 metre  Additional extraction hose for your process  Do not move one. Remember it’s there to save your life and others A1 Training & Safety 2013
  • 19. Confined spaces Personal Air Monitor PAM: • All Personnel MUST have a PAM with them. • Check that the PAM registers 19.3% - 23% • Upon activation:95 Db audible alarm, Red flashing light, Vibrates • You should immediately vacate the area and inform your supervisor • Any defects should be reported & unit returned to the point of issue A1 Training & Safety 2013
  • 20. Confined Spaces Safe Air Monitor Demo A1 Training & Safety 2013
  • 21. Confined spaces No entry:  No extraction or ventilation  No atmosphere testing  No emergency lighting  No detection equipment  Gross misconduct Entering could cost you your life! A1 Training & Safety 2013
  • 22. Confined spaces Emergency procedures:  Evacuate the confined space  Don’t attempt the rescue yourself  Get help immediately!  Use emergency contact procedure  Give details of confined space location  Lead the professionals to the incident  Stay outside the confined space A1 Training & Safety 2013
  • 23. Confined spaces Learning from experience:  Worker asphyxiated by chemical fumes whilst working in a tank  Build up of Propane in unidentified confined space causing severe burns when ignited.  Fatality following a pressurised suit being connected to an argon supply.  8 workers killed due to an oxygen leak.  3 Contractors Killed emptying tanks. A1 Training & Safety 2013
