During arc welding inside a steel compartment, dizziness is reported despite normal PPE use. Which control should be applied first?
Increase helmet shade
Add forced ventilation
Reduce welding current
Change filler material
Which condition most directly increases the risk of arc eye during routine welding tasks?
Incorrect glove type
Inadequate filter shade
Excessive joint gap
Poor cable routing
Why are oxygen cylinder fittings kept free from oil and grease?
To prevent valve seizure
To reduce flow resistance
To avoid spontaneous ignition
To maintain pressure stability
A welder completes hot work on deck near insulation material. What safety action remains essential?
Shut down power supply
Conduct post-work fire watch
Remove welding cables
Store electrodes properly
Which factor best explains electric shock risk during welding in damp conditions?
Increased arc length
Lower circuit resistance
Reduced electrode coating
Excessive cable heating
What is the primary safety function of a flashback arrestor in gas welding?
Regulates gas pressure
Stops reverse flame travel
Filters combustible impurities
Improves flame stability
Which practice best minimizes exposure to welding fumes in enclosed spaces?
Intermittent welding sequence
Use of local exhaust system
Reduced electrode diameter
Increased travel speed
A welding cable shows damaged insulation but remains operational. What is the safest action?
Monitor during operation
Isolate and replace cable
Reduce output current
Increase grounding area
Why is synthetic clothing considered unsafe for welders?
It limits body movement
It melts under heat exposure
It increases static charge
It restricts heat dissipation
Which control measure addresses welding hazards at the source level?
Wearing fire-resistant PPE
Installing welding screens
Removing flammable materials
Issuing safety briefings
Who is primarily responsible for ensuring welding follows approved safety procedures?
Equipment manufacturer
Authorized welding personnel
Maintenance department
Safety signage provider
What is the main reason for securing gas cylinders in an upright position?
Prevent regulator damage
Maintain correct gas mixing
Avoid accidental valve failure
Improve storage efficiency
Which situation most justifies respiratory protection during welding?
Outdoor welding operation
Low-current tack welding
Poorly ventilated enclosure
Short-duration repair work
Which action best supports emergency preparedness during welding operations?
Recording weld parameters
Keeping exits unobstructed
Labeling filler materials
Preheating base metal
What is the primary purpose of grounding welding equipment?
Stabilize arc characteristics
Prevent voltage fluctuation
Provide safe current return path
Improve weld penetration
