4. Compressed gas in three forms
COMPRESSED (CYLINDER)
Liquefied (CO2; N2 & O2 IN PORTABLE
LIQUID CYLINDERS )
DISSOLVED (ACETYLENE)

5. Three Classes of Gas
FLAMMABLE
NON-FLAMMABLE
POISON

6. Flammable Gases
Examples are:
Acetylene
Hydrogen
Propane
Butane

8. Non-Flammable Gases Examples are: Nitrogen Argon Helium Air
Carbon Dioxide
Oxygen

10. Poison Gases Examples Toxic Examples Corrosive Arsine Chlorine
Phosphine
Hydrogen Sulphide
Examples
Corrosive
Chlorine
Hydrogen Chloride

12. Oxidising Gas
OXYGEN

14. Cylinder Use

15. IDENTIFY THE GAS!! Before Using Cylinder
READ THE LABEL! DO NOT DEPEND ON THE COLOUR OF THE CYLINDER

17. Cylinder Use
NEVER REMOVE THE VALVE PROTECTION CAP UNTIL THE CYLINDER IS SECURED AND READY FOR USE!!

18. Cylinder with Fixed Cap
(Tulip Type)

19. Cylinder Use
NEVER USE AN ADAPTOR TO MAKE A CYLINDER FIT A REGULATOR OR OTHER EQUIPMENT!!

20. STAND TO THE SIDE OF THE REGULATOR WHEN OPENING
Cylinder Use
OPEN VALVE SLOWLY!!
STAND TO THE SIDE OF THE REGULATOR WHEN OPENING

21. 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

22. LEAK CHECK CYLINDER CONNECTIONS
Cylinder Use
LEAK CHECK CYLINDER CONNECTIONS
WITH A SOAPY SOLUTION
NEVER USE A FLAME!!

23. Cylinder Use
NEVER STRIKE AN ELECTRICAL ARC ON A COMPRESSED GAS CYLINDER!!

24. Cylinder Use
CLOSE CYLINDER VALVES WHEN NOT IN USE!!

25. (CALL YOUR GAS SUPPLIER)
Cylinder Use
DO NOT TRANSPORT A LEAKING CYLINDER!!
(CALL YOUR GAS SUPPLIER)

26. Cylinders & OSHA (Occupational Safety & Health Agency, USA) MOST CITED VIOLATIONS

CYLINDERS NOT PROPERLY SECURED

27. Cylinder Storage

28. Cylinder Storage SEPARATE STORAGE AREAS BASED UPON TYPES OF GASES
FULL & EMPTY CYLINDERS

30. Cylinder Storage
SECURE THE CYLINDER WITH VALVE PROTECTION CAP IN PLACE!!
(CHAIN, TIED, ETC.)

32. Cylinder Storage
STORE CYLINDERS IN WELL VENTILATED AREAS THAT DO NOT EXCEED 50 OC
