Industrial Gases - ACETYLENE (C2H2)
Acetylene is a highly flammable and colorless gas. It has a garlic-like odor. It poses fire And explosion hazards at very low concentrations. Acetylene is an unstable gas and is Filled in cylinders packed in a porous mass. Generally it is supplied as dissolved Acetylene. Special care is required during examination and filling the cylinder. Commercial Production of Acetylene is done using Calcium Carbide.
Applications
Acetylene when mixed with Oxygen burns violently and produces an extremely hot
Flame. It is used very commonly for metal cutting in the steel industry. Acetylene
Produces a highly luminous flame. In line with these characteristics, following are the
most common applications:
- Metal Fabrication
- Atomic Absorption
- Marine Lighting
Hazards Identifications
Dissolved gas extremely flammable.
The gas is lighter than air, and may spread long distances. Distant ignition and flash back
Are possible. Acetylene gas may decomposes explosively at elevated temperatures and
Pressures. It can form very explosive metallic salts such as with copper and silver.
Handling and Storage
Close valve after each use and when empty. Cylinders must not be recharged except by
Or with the concern of owner. Acetylene cylinders should be stored upright and be firmly
Secured to prevent falling or being knocked over.
Keep the quantity stored as small as possible.
