  1. Compressed Air Safety

  2. Introduction • Compressed air is second only to electricity as the most popular source of energy used in today’s work environments • Because electricity isn’t associated with compressed air most people don’t recognize the dangers posed by this energy • Just like electricity, compressed air can be deadly if not treated with respect & used safely

  3. Today’s Presentation • Why is Compressed Air So Popular? • Compressed Air Equipment Safety • How to Use Compressed Air Safely • Review Quiz

  4. Why is Compressed Air So Popular? • Its readily available, easily stored and distributed • Can be generated using electric motors or gas engines • It’s a very reliable power source • It’s used for pressure application of 80 to100 PSI vs. where as hydraulic is used for 1000 PSI or greater

  5. Why is Compressed Air So Popular? • It’s a compressible gas and therefore absorbs shock better than hydraulic systems • Tools have a large power to weight & size ratio when compared to similar electric tools • Tools can be operated indefinitely with out fears of overheating

  6. Why is Compressed Air So Popular? • Overloading the tools simply stops it and doesn’t damage them as opposed to electric tools • Can be used in wet environments as opposed to electrical tools • Can be used in explosive environments e.g. Mining, tunneling and explosive manufacturing

  7. Compressed Air Equipment Safety • Regularly drain moisture from the air tank to prevent rust & tool contamination • Ensure the safety relief valves are present and working • Ensure the compressor drive guarding is in place as compressors start automatically

  8. Compressed Air Equipment Safety • All components must be rated for the maximum pressure of the compressor. • Air supply shutoff valves should be located (as near as possible) at the point-of-operation.

  9. Compressed Air Equipment Safety • Air hoses should be kept grease & oil free to reduce the possibility of deterioration. • Hoses should not be strung across floors or aisles where they create trip hazards. • When possible, air supply hoses should be dropped from overhead.

  10. Compressed Air Equipment Safety • Hose ends must be secured to prevent whipping if accidentally cut • Never use raw compressed air for supplied air breathing systems • Always lock-out & release compressed air before working on it. It’s a source of stored energy

  11. How to Use Compressed Air Safely • Always inspect compressed air equipment before use, a loose air hose can be a dangerous bullwhip and can seriously injure or kill the user • When using compressed air always wear safety glasses & other appropriate PPE for example hearing protection, or face shield. Noise above 85db requires protection

  12. How to Use Compressed Air Safely • Never use compressed air as a practical joke • Never point an air hose or tool at any part of your body or another person • Compressed air must never be used under any circumstances to clean dirt and dust from clothing or off a person’s skin.

  13. How to Use Compressed Air Safely • When shop air must be used for cleaning it must be regulated to 15 psi or less unless equipped with diffuser nozzles. ¾’s of all injuries occur when debris is blown into an eye, ear or face. • Even 12 psi of compressed air can be driven into the flesh or eyes. • Air can be driven into blood creating embolisms causing strokes or death.

  14. How to Use Compressed Air Safely • Before disconnecting an air tool shut off the air supply and bleed the tool. (unless it has quick disconnects) • Static electricity can be generated through the use of air tools. Grounding must be used where explosive atmospheres can be present.

  15. Summary • Today I have covered: • Why is Compressed Air So Popular • Compressed Air Equipment Safety • How to Use Compressed Air Safely • And Provided a Review Quiz • Are they any Questions?
