Welding Safety

These flashcards cover essential safety protocols and hazards associated with welding.

What are the hazards associated with visible light in welding?

Visible light can cause eye strain and temporary or permanent blindness.

What can ultraviolet light rays cause during welding?

Ultraviolet light rays can cause burns to exposed skin and blistering of the eyeballs, known as arc flash.

What is the maximum temperature that can be reached during welding?

The extreme heat can reach from 3,316°C up to 33,538°C.

What are the types of burns that can be received from welding?

First, second, or third degree burns from hot metal, slag, or sparks.

What personal protective equipment (PPE) should be worn during welding?

Safety glasses, a full face visor, leather or wool clothing, leather gauntlet gloves, and fully laced boots.

What are welding fumes and gases?

Fumes are small condensed particles of metal or other substances vaporized during welding; gases used include argon and carbon dioxide, which can cause suffocation.

What is metal fume fever?

A condition that produces flu-like symptoms due to inhalation of zinc oxides and other fumes.

What are Occupational Exposure Limits (OELs)?

The maximum concentrations of a hazardous substance that a person can be exposed to without suffering adverse health effects.

What should be done to ensure safe ventilation during welding?

Keep your head out of the welding plume and utilize natural or local ventilation methods.

What are the electrical hazards while welding?

Electric shocks can occur with voltages lower than 250V, and a current of only 15mA can prevent grip release.

What precautions should be taken regarding fire prevention in welding?

Check for fire and explosion hazards, obtain permits, use gas sniffers, and know the location of fire extinguishers.
