General Safety Precautions To Be Taken During Handling / Usage Of Acetylene Cylinders

1)      Acetylene is a colorless, highly reactive and extraordinarily flammable gas.
2)      It has a sharp garlic-like odor and Lighter than air.
3)      Acetylene is dissolved in acetone at low pressure, stabilizing it against decomposition.
4)      Drains & Vents connected to flammable gas connecting equipment to safe, preferably outside locations.
5)      Check valves / Block valves / Non-return valves should be inspected before usage.
6)      Provide positive isolation on lines connected to the process to ensure that backflow of explosive gases cannot occur.
7)      Cylinders contain fusible plug, which melt at 98-104 0C.
8)      Do not discharge cylinders at pressure above 1.0 Kg/cm2.
9)      In case of fire, use water, Co2, DCP extinguishers.
10)  Eliminate all possible sources of ignition as it is ignitable by static electricity.
11)  Cylinders should be separately stored from Oxygen and other oxidizers. (Minimum 20 ft distance is to be maintained)
12)  FLP fittings should be used in this area. (Class I Hazardous area)
13)  Do not allow storage temperature to exceed 52 0C.
14)  Follow FIFO (First in And First Out) to prevent cylinders from being stored for long periods.
15)  All acetylene piped systems and associated equipments must be grounded.
16)  Do not open the cylinder valve more than one and one-half turns.
17)  Check leakages of gas with soap water solution only.
18)  Cotton clothing is recommended for operating staff to prevent static build up.
19)  Safety shoes, goggles, air line respirator and hand gloves should be worn.
20)  Can form explosive mixtures with air and an oxygen deficient atmosphere.
21)  Acetylene is non-toxic gas.
22)  Never use copper piping for acetylene service. Only steel or wrought iron pipes should be used.

23)  Air purifying (cartridge filters) respirators will not function.
