  1. Session overview This session will provide an overview of considerations when responding to a MVA • LP Gas hazards • Scene safety & security • Personal safety • First aid • Emergency management

  2. MVA Awareness STEP 1 On arrival at incident (or on the way if possible) do an assessment / Size Up of the scene to identify any EXISTING or POTENTIAL risks, example:- • Hazardous materials • Leaking fuel or gas • Downed power lines • Potential ignition source • Unstable loads likely to fall

  3. LP Gas hazards • Where a person is trapped in a vehicle with an LPG leak, NO attempt should be made to extricate the person whilst the leak exists. • Ensure area has been secured • Control any LPG leaks by • Isolating main service valve • Capping connections • Crimping pipes • Plug holes. • If unable to control leak; use fog sprays to disperse gas

  4. Automotive LPG Common Faults & Actions • Leaking Filler Valve or remote filler • Leaking filler valve fitted to cylinder • Cylinder Leaks - Leak from cylinder valves seal or spindle - Leak from cylinder valves where they screw into the cylinder caused by sealant breakdown - Leak from damaged cylinder ALL LEAKS FROM THIS POINT ON CAN BE FIXED BY CLOSING THE SERVICE VALVE

  5. Automotive LPG Common Faults & Actions • Leak from service line or gas lock-off Shut down service valve at cylinder, this will close off supply. LPG will take time to dissipate from the line. If unable to shut down service valve, bending the service line over a number of times may help to close off the supply.

  6. EMERGENCY INFORMATION PANELS • 1. Technical Name • 2. UN Number • 3. Hazchem Code • 4. Class Diamond • 5. Emergency Contact • 6. Specialist Contact LPG UN NO. 1075 Hazchem 2YE IN EMERGENCY DIAL 000, POLICE OR FIRE BRIGADE SPECIALIST ADVICE AUSTRALIAN CHEMICALS LTD. (02) 9987 6543

  7. Incident Handling Emergencies involving cylinders • Approach uphill & upwind • Eliminate all sources of ignition • Evacuate • Water fog to disperse vapour • Cool the cylinder

  8. Hazmat Awareness • Hazmat Action Guide (HAG Sheet) • Work through HAG Sheet • For an extra exercise use petrol (petrol 1270) • Petrol leak from car fuel tank. (60 lts)

  9. Hybrid Car Hazards • Increased number of hybrid vehicles are on the road and they create their own hazards. • View the hybrid vehicle presentation

  10. A SYSTEMS APPROACH

  11. MVA Awareness Step 2 Position the Pumper / Tanker to: • Protect you, fellow firefighters and the injured from other traffic • Ensure appliance does not become trapped if incident becomes worse • Allow access for ambulance, rescue crews • Avoid parking over skid marks and debris used for investigation • Avoid parking under power lines

  12. Appliance Parking • Fend off position if the Rescue is first arriving appliance on scene • If scene secured by Police etc. then park Rescue appliance in the following manner

  13. MVA Awareness • Park Rescue as close as practical to scene outside action circle • Keep access open for Ambulance to transport patient

  14. MVA Awareness Step 3 Crew Leader to ensure: • Tasking of crew • A 38mm charged hose line with fog nozzle • Dry Chemical extinguisher on hand • Wordback is given • Crew members exposed to minimum trauma

  15. MVA Awareness Step 4 Ensure that crews: • Wear appropriate PPE, especially to avoid contamination of yourself with body fluids from the injured • Double gloving (surgical and leather) • Disconnect the Negative battery lead • Be aware of Air Bag Release

  16. Minimum Protective Clothing

  17. Bloodborne Pathogen • Bloodborne Pathogens what are they ? • Examples of Bloodborne Pathogens are: • HIV • HEPATITIS A • HEPATITIS B • HEPATITIS C

  18. MVA Awareness Step 5 First on Scene: • Consider welfare of the injured parties • Basic first aid (D.R.A.B.C.D) • Be aware of the potential for spinal injuries • Crush syndrome is a life threatening condition. It must be suspected in all persons trapped by the limbs. Extrication should be done in a controlled environment.

  19. Crush Injuries • These injuries often involve damage to a great deal of skin, muscle and bone and Medical Aid should always be sought. • There may be serious external and Internal bleeding. In particular there may be damage to the blood vessels supplying a limb, therefore, if released and rescue is delayed, the part may be lost due to a prolonged lack of oxygenated blood. • In some cases where the part remains crushed for more thanone hour, serum will pour into the injured tissues causing them to become swollen and hard, blood pressure will fall and shock will develop.

  20. Crush Injuries • Signs and Symptoms • History of incident e.g. Person crushed /trapped by machinery. • Crushed part may be tingling or numb. • Swelling and hardness around injury. • Bruising and blisters. • Crushed or trapped limbs will be Cool, Pale and Pulse less if arteries are compressed. • Shock i.e. skin Cold/Pale/Clammy.

  21. Crush Injuries • First Aid Treatment • Confirm with “VICFIRE” that an Ambulanceisrequired URGENTLY • Where a person has been trapped with a crushed limb for longer than 1 HOUR ensure that Ambulance is in attendance before attempting release.

  22. MVA Awareness Step 6 Who is in charge? Policeare the combating authority and generally we are in support capacity • If fire or hazmat involved we are the combating authority • Ensure the appropriate tabard is worn. CFA Commander where in support Incident Controller when in charge of incident

  23. MVA Awareness Step 7 Traffic Control This is a Police Job • We can temporarily assist them • We can stop traffic • We cannot re-direct traffic • Do not get involved in jobs (traffic control is not our responsibility)

  24. MVA Awareness Step 8 Security of scene • Ensure the scene is not disturbed for investigation needs. (Skid marks, debris, ect) • Ensure property involved in the incident is protected and not pilfered

  25. Working with Ambulance & Rescue Crews • Allow them space to work • Crew Leader to make themselves known to other authorities as CFA contact person

  26. MVA Awareness Other Considerations • Lighting • Relief Crews • Release from the incident ASAP, don’t stay around and get exposed to trauma • Motor vehicle accidents may be stressful therefore consider Critical Incident Stress support • Any member of a brigade, or family member, can request CIS assistance through your Duty Officer
