Why is oxy-acetylene dangerous?

Acetylene poses unique hazards based on its high flammability, instability and unique storage and transportation requirements. Acetylene is highly unstable. High pressure or temperatures can result in decomposition that can result in fire or explosion.

What are the dangers of welding?

Health hazards from welding, cutting, and brazing operations include exposures to metal fumes and to ultraviolet (UV) radiation. Safety hazards from these operations include burns, eye damage, electrical shock, cuts, and crushed toes and fingers.

What are the safety precaution before using a oxy-acetylene welding?

Agricultural Engineering Safety Lesson Plan: Oxyacetylene Welding Safety

• Wear personal protective equipment.
• Fasten cylinders securely.
• Never use oil on welding equipment.
• Open cylinder valves correctly.
• Keep the tip pointed away from your body.
• Light the flame with an approved lighter.

Why does acetylene explode?

If a cylinder filled with compressed acetylene gas is exposed to a flashback, starts to warm up or vibrate, or if such a cylinder was involved in a fire, its contents may have begun to decompose. This process can become self-sustaining causing the cylinder to explode, in some cases hours after the initiating event..

Are acetylene torches safe?

Remember, the improper use of an oxy-fuel cutting torch can cause serious injury or death. These torches are probably the most dangerous piece of welding equipment out there, and the oxyacetylene process produces a flame over 3000 degrees C.

What are the 10 major hazards in welding operations?

Welding Safety Hazards

• Pneumonia. Regular exposure to welding fumes and gases can result in a lung infection which could then develop into pneumonia.
• Occupational asthma.
• Cancer.
• Metal fume fever.
• Throat and lung irritation, including throat dryness, tickling of the throat, coughing and tight chests.

Can cutting torch explode?

This can be a major explosive hazard. This will create copper acetylide, which again, may explode. Flashback and Backfire. Flashback is when the flame disappears from the end of the welding tip and gas burns within the torch or beyond into the hoses and regulators.
