Health, Safety and Good Workshop Practice During Qualification Testing
Why it is examined
Qualification testing happens in a workshop under realistic conditions. Safety and good practice are part of the assessment because a welder who ignores them is not competent in the full sense. Questions test hazard awareness and correct workshop behaviour.
Hazards to know
- Arc radiation - arc eye, skin burns; use a proper helmet with correct shade and protective clothing.
- Fume and gases - welding fume, shielding gases (asphyxiation risk in confined spaces); use extraction/ventilation and RPE where required.
- Electric shock - wet conditions, damaged cables, incorrect polarity; check equipment, use dry gloves, ensure earthing.
- Fire and explosion - sparks, hot slag, flammable materials; hot-work permits, fire watch, screens.
- Burns and hot metal - gloves, aprons, handling hot test pieces.
- Noise, grinding dust, manual handling - general workshop hazards.
Good workshop practice
- Housekeeping: clear area, cables routed safely, no trip hazards.
- Correct PPE for the process.
- Equipment checks before use.
- Test pieces marked and stored safely.
- Confined-space and hot-work procedures followed.
Traps
- Assuming "just a test" relaxes safety rules - it does not.
- Forgetting gas asphyxiation in confined spaces (argon/CO2 displace oxygen).
- Overlooking fire watch after hot work - smouldering can start later.
Rule of thumb
Before striking an arc: PPE on, area clear, extraction on, fire precautions in place, equipment checked.
Worked example
A welder is asked to weld a test piece in a confined tank. Correct answer: confined-space procedure, gas monitoring, ventilation/extraction, rescue plan, attendant outside - not simply "wear a helmet and weld".
