1. COMPRESSED GASES

2. Compressed Gases Chemicals include oxygen, argon, nitrogen, helium, acetylene, hydrogen, nitrous oxide, carbon dioxide, ammonia, chlorine, etc. Compressed gases used in bulk systems or portable cylinders Industry uses include welding, cutting, operating tools, transferring liquids, blowing agents, laboratories, etc.

3. Hazards of Compressed Gases Explosion Flammability Corrosive Toxicity Reactivity Air displacing Check MSDS for specific hazards

4. Markings or Labels Name of the compressed gas Hazards of the compressed gas National Fire Protection Association (NFPA) labels Department of Transportation (DOT) labels Do not remove any labels

5. Identification of compressed gas Identification of Compressed Gas

6. ACETYLENE PROPANE HYDROGEN ETHYLENE OXIDE BUTANE FLAMMABLE GASES

7. NON-FLAMMABLE GASES NITROGEN ARGON HELIUM CARBON DIOXIDE NITROUS OXIDE

8. OXIDIZERS OXYGEN NITROUS OXIDE

9. POISON GASES SPECIALTY GASES AMMONIA

10. Manual Cylinder Handling Close the valve and put on the cap Do not “walk” cylinder by holding onto valve stem or cap Never roll a cylinder on its side Use a hand truck with a secure system

11. Cylinder Storage Area Dry, well ventilated, protected from weather Away from combustibles, heat sources, electrical systems No sparks, smoking, open flames Oxygen separated from fuels Upright, secured, valve cap on Not in elevators, staircases, hallways, etc. Sign requirements

12. Cylinder Use Upright and secure Away from flames, sparks, electricity Keep oil, grease, flammables off cylinders Open valve by hand, if tools required don’t use the cylinder Open valve slowly with hand to the side Don’t tamper with safety devices

13. Cylinder Inspection CHECK FOR: DENTS CUTS OR GOUGES CORROSION AND PITTING BULGES CRACKS AND FLAWS HOLES AND TEARS IF FOUND, DO NOT USE THAT CYLINDER SYSTEM

14. General Safety Precautions Only accept and use DOT approved cylinders Do not drop cylinders Protect cylinders from cuts and abrasions Don’t use cylinders for unintended function such as a roller or support Don’t tamper with safety valves Caps on whenever not in use

15. General Safety Precautions READ ALL LABELS - IF NONE DO NOT ASSUME A CYLINDER CONTAINS A SPECIFIC GAS BASED ON COLOR BE AWARE OF ALL HAZARDS ASSOCIATED WITH THE COMPRESSED GASES THAT YOU WILL BE USING REVIEW MATERIAL SAFETY DATA SHEETS, (MSDS), FOR SPECIFIC GASES A STANDARD 250 CUBIC FOOT CYLINDER PRESSURIZED TO 2500 PSIG CAN ATTAIN A SPEED OF 34 MPH IN ONE- TENTH OF A SECOND AFTER VENTING FROM A BROKEN CYLINDER CONNECTION
