Question 2

A welder notices that a cable insulation is cracked and the copper conductor is exposed. What is the correct action?

Accepted Answer

Stop work immediately and replace or repair the cable before use

Question 3

What is the primary hazard associated with welding on galvanized steel?

Accepted Answer

Generation of zinc oxide fumes that can cause metal fume fever

Answer

Heating galvanized steel releases zinc oxide fumes, which can cause metal fume fever if inhaled without adequate ventilation or respiratory protection.

Question 4

Which ventilation method is most effective for controlling welding fumes at the source?

Accepted Answer

Local exhaust ventilation (LEV) positioned near the arc

Answer

Local exhaust ventilation captures fumes at the point of generation before they disperse into the breathing zone.

Question 5

What does OSHA's lockout/tagout (LOTO) procedure require before a welder performs maintenance on welding equipment?

Accepted Answer

Isolating and de-energizing the equipment and verifying zero energy state before work begins

Answer

LOTO requires physically isolating energy sources, applying locks and tags, and verifying the equipment is de-energized before maintenance.
