What are the hazards associated with GTAW?

The hazards associated with Gas Tungsten Arc Welding (GTAW) are varied and include multiple risks that welders must be aware of to ensure safety in the workplace. The correct choice identifies electric shock, UV radiation, hot metal burns, and inhalation of fumes and gases as significant hazards.

Electric shock is a concern due to the high voltage and current used in the welding process, which can cause serious injury or even be fatal if preventative measures are not taken. Proper grounding and the use of insulated equipment are crucial to mitigate this risk.

UV radiation is another significant hazard that arises from the intense light produced during welding. This radiation can cause skin burns (similar to sunburn) as well as damage to the eyes, leading to conditions such as flash burn or more severe ocular injuries. Welders must use appropriate protective gear, such as welding helmets with adequate UV shielding, to protect themselves from these risks.

Hot metal burns occur due to the high temperatures involved in GTAW. The welder is at risk from molten metal and spatter, which can result in severe burns if protective clothing is not worn. Thus, using flame-resistant materials and ensuring proper posture to avoid exposure is critical for safety.

Finally, inhalation of fumes and gases generated during the
