- 1. Safe Storage, Handling & Use of Compressed Gases
- 2. Compressed gas in three forms • COMPRESSED (CYLINDER) • Liquefied (CO2; N2 & O2 IN PORTABLE LIQUID CYLINDERS ) • DISSOLVED (ACETYLENE) Three Classes of Gas • FLAMMABLE • NON-FLAMMABLE • POISON
- 3. Flammable Gases Examples are: •Acetylene • Hydrogen • Propane • Butane
- 4. Non-Flammable Gases Examples are: • Nitrogen • Argon • Helium • Air • Carbon Dioxide • Oxygen
- 6. Before Using Cylinder IDENTIFY THE GAS!! READ THE LABEL! DO NOT DEPEND ON THE COLOUR OF THE CYLINDER Cylinder Use
- 8. Cylinder Use NEVER REMOVE THE VALVE PROTECTION CAP UNTIL THE CYLINDER IS SECURED AND READY FOR USE!!
- 9. Cylinder with Fixed Cap (Tulip Type)
- 10. Cylinder Use NEVER USE AN ADAPTOR TO MAKE A CYLINDER FIT A REGULATOR OR OTHER EQUIPMENT!!
- 11. Cylinder Use OPEN VALVE SLOWLY!! STAND TO THE SIDE OF THE REGULATOR WHEN OPENING
- 12. Slide 12 Asia Industrial Gases Association 298 Tiong Bahru Road, #20-01 Central Plaza, Singapore 168730 Internet: www.asiaiga.org Cylinder Use IF A CYLINDER VALVE DOES NOT OPERATE EASILY, CONTACT YOUR GAS SUPPLIER FOR ASSISTANCE!! NEVER USE EXCESSIVE FORCE TO OPERATE A CYLINDER VALVE
- 13. Cylinder Use LEAK CHECK CYLINDER CONNECTIONS WITH A SOAPY SOLUTION NEVER USE A FLAME!!
- 14. Cylinder Use • NEVER STRIKE AN ELECTRICAL ARC ON A COMPRESSED GAS CYLINDER!! • CLOSE CYLINDER VALVES WHEN NOT IN USE!! DO NOT TRANSPORT A LEAKING CYLINDER!! (CALL YOUR GAS SUPPLIER)
- 15. Cylinder Storage SEPARATE STORAGE AREAS BASED UPON • TYPES OF GASES • FULL & EMPTY CYLINDERS • SECURE THE CYLINDER WITH VALVE PROTECTION CAP IN PLACE!! (CHAIN, TIED, ETC.) • STORE CYLINDERS IN WELL VENTILATED AREAS THAT DO NOT EXCEED 50 OC
- 16. Cylinder Storage • PROTECT CYLINDERS FROM PHYSICAL DAMAGE • KEEP AWAY FROM ELECTRICAL CIRCUITS • AVOID EXCESSIVE MOISTURE
- 19. Cylinder Handling • DO NOT ROLL OR DRAG CYLINDERS • USE A HAND TRUCK TO MOVE CYLINDERS • KEEP VALVE PROTECTION CAPS IN PLACE WHILE IN STORAGE, DURING HANDLING, AND IN TRANSPORTATION!! • NEVER ATTEMPT TO LIFT A CYLINDER BY THE VALVE PROTECTION CAP!! • NEVER TRANSPORT CYLINDERS IN CAR TRUNKS OR ENCLOSED VEHICLES!!
- 23. X
- 26. Flammable Gases NO SMOKING NEAR FLAMMABLE GASES!!
- 27. Flammable Gases USE SPARK PROOF TOOLS!!
- 28. Flammable Gases FLAMMABLE GASES SHOULD BE STORED 6 METRES AWAY FROM • OXIDISERS • COMBUSTIBLES • IGNITION SOURCES
- 29. Flammable Gases LIMIT QUANTITIES OF FLAMMABLE GASES STORED INSIDE A BUILDING!! ONE EXAMPLE FROM A GUIDELINE: • 60 M3 • 150 Kg of LPG (LIMIT IS BEST SET AFTER A PROPER RISK ASSESSMENT) • THIS DOES NOT INCLUDE CYLINDERS IN ACTUAL USE OR ATTACHED FOR USE.
- 30. Flammable Gases FOLLOWING THE EXAMPLE GIVEN, STORAGE OF FLAMMABLE GASES IN EXCESS OF 60 M3 OR 150 KG SHALL BE KEPT • IN A SEPARATE ROOM • IN A SEPARATE BUILDING • OUTDOORS
- 31. Flammable Gases ACETYLENE WHEN USING A CYLINDER: • STORE CYLINDER UPRIGHT • KEEP OUTLET PRESSURE AFTER REGULATOR TO MAXIMUM 1 BAR(G) • OPEN CYLINDER VALVE 1/2 TO 3/4 TURN
- 32. Special precautions for POISON GASES (TOXIC & CORROSIVE)
- 33. Poison Gases HAVE A DETAILED EMERGENCY ACTION PLAN IN PLACE!!
- 34. Poison Gases LIMIT QUANTITIES OF POISON AND CORROSIVE GASES IN USE AND STORAGE!!
- 35. Poison Gases STORAGE OF POISON GASES • OUTDOORS • INDOORS FORCED VENTILATED GAS CABINET
- 36. Poison Gases WEAR ALL REQUIRED RESPIRATORY PROTECTION AND/OR PROTECTIVE CLOTHING!!
- 37. Poison Gases FOR CORROSIVE GASES • SAFETY SHOWER & EYEWASH READILY AVAILABLE
- 38. Summary NEVER USE A GAS (ANY GAS) UNLESS YOU ARE TRAINED IN ITS USE AND UNDERSTAND ITS HAZARDS!!
- 39. Summary MATERIAL SAFETY DATA SHEETS (MSDS) ARE A GOOD SOURCE FOR EMPLOYEE TRAINING MATERIAL!!
