Total questions: 15
Worksheet time: 8mins
A welder uses a helmet with the incorrect filter shade that is slightly lighter than required. Which hazard is most likely over time?
Corneal rusting
Photokeratitis
Retinal detachment
Thermal arc burn
During arc welding, why must clothing be fire-resistant and not synthetic?
Synthetic fibers trap UV radiation
Synthetic fibers can melt and bond to skin
Flame-retardant fabrics give electrical insulation
Fire-resistant clothing eliminates all burn hazards
Which ventilation strategy is MOST aligned with standard practice for controlling welding fumes?
Relying on natural airflow if the door is open
Using a fan pointed toward the welder
Local exhaust ventilation at the arc source
Increasing shop temperature to boost air movement
A welder sees moisture on gloves before starting SMAW. What is the BEST immediate action?
Continue welding if voltage is low
Wipe the gloves and continue
Replace gloves and dry the area
Weld only short segments to reduce exposure
While welding, spatter reaches a pile of oily rags nearby. What is the most appropriate response?
Step back and continue monitoring
Extinguish and remove combustible material immediately
Cover it with a welding blanket after the pass is finished
Inform a supervisor after completing the task
A welder notices dizziness after prolonged welding in a confined corner. What should be done FIRST?
Switch to a darker filter shade
Stop and improve ventilation or exit the space
Change electrode type
Increase amperage to reduce fume concentration
Two welders are working: Welder A has correct PPE but poor cable maintenance; Welder B has perfect equipment but no face shield. Which presents greater immediate risk and why?
Welder A, because shock risk is fatal and immediate
Welder B, because facial injuries are more common
Welder A, because cable faults only cause minor shocks
Welder B, because PPE violations are the top OSHA citation
A shop has excellent PPE compliance but frequent small fires. Which root control is MOST lacking?
Arc intensity control
Hot work permitting
Housekeeping and material management
Respirator fit-testing
A shielding gas cylinder is stored near a welding machine's power switch panel. Which hazard category applies?
Confined space hazard
Electrical-heat interaction hazard
Oxygen deficiency hazard
Flammable vapor ignition fire hazard
A safety officer must choose ONE improvement for a workshop with frequent near-miss eye injuries. Which is the BEST intervention?
Provide more advanced helmets
Mandate safety goggles under helmets and improve supervision
Install brighter lighting at each booth
Reduce welding amperage limits
Which condition justifies immediate cancellation of a hot work permit?
Fire watch temporarily changes position
Gas readings exceed safe limits during re-test
CO₂ extinguishers are almost discharged but still usable
Welder changes electrode size
A supervisor must decide how to reduce fume exposure during tank-top welding. Which option is BEST?
Mandate respirators as primary control
Optimize forced ventilation and extraction
Limit welding time to 15-minute intervals
Use only low-fume rods
A fire watch reports normal conditions, but the Safety Officer rejects closing the permit. Which hidden hazard most justifies this?
Temperature of welded plate remains elevated
No one logged out on the permit control sheet
The portable fan is still running
The arc-lighting shield is damaged
A motor is located near the welding site and cannot be removed easily. To comply with hot work precautions, the best action is to:
Wrap the motor with fire blankets and isolate its power
Ask the welder to stand farther from the equipment
Apply water mist around the motor during welding
Post a warning sign and continue
A fire watch is required during and after shipboard hot work because:
PPE is insufficient to stop heat transfer
Re-ignition may occur from hidden combustibles
The permit automatically expires otherwise
SOLAS only allows fire watch for enclosed spaces
