What is Acetylene?

Acetylene is colorless, with a faint garlic-like odor, and very flammable. It is widely used as fuel and chemical building block. Pure acetylene is unstable, so it is commonly handled in solution. Acetylene is used for welding and cutting due to the high temperature of the flame. Calcium carbide was used to generate acetylene for portable lighting. Acetylene is used to volatilize carbon in radiocarbon dating of archaeological samples. Acetylene is extremely flammable and easily explodes under pressure.

Acetylene Exposures and Health Risks

The primary risks of acetylene are due to the dangers of explosion or flame. Burns and frostbite are easily obtained from contact with expanding gas. Burns and frostbite should immediately be seen by a medical professional. Should contact occur, immediately flush area with plenty of water and remove any contaminated clothing. Inhalation can cause headache and dizziness, or even loss of consciousness in extreme cases. Should symptoms of inhalation be noticed, remove to fresh air, providing oxygen if necessary.

Regulations

ACGIH recommends a TLV-TWA of 5 mg/m3 for welding fumes. ACGIH labels acetylene as a simple asphyxiant in the case of overexposure. Acetylene does not have listed exposure regulations by NTP, OSHA, NIOSH, or IARC.
