AWS Certified Welding Inspector — FundamentalsSafetyMedium
A welding inspector is observing a shielded metal arc welding (SMAW) operation in a confined space. The welder collapses due to an unknown atmospheric hazard. Which of the following is the MOST immediate and critical action the inspector should take?
- AVentilate the confined space using a portable fan.
- BAttempt to retrieve the welder immediately to safety.
- CEnter the confined space with an air-purifying respirator to assess the situation.
- DActivate the confined space rescue plan and notify emergency services.
Show answer & explanationAnswer & explanation
Correct answer: D. Activate the confined space rescue plan and notify emergency services.
In a confined space emergency, the immediate priority is to activate the established rescue plan and notify emergency services. Unauthorized entry or attempting a rescue without proper training and equipment can endanger more lives.
Why the other options are wrong
- A. Ventilation might be part of the rescue, but it's not the immediate, overarching critical action without knowing the hazard or having a rescue plan in place.
- B. Attempting a rescue without proper training and equipment can lead to multiple casualties in a confined space.
- C. Entering a confined space with an air-purifying respirator without knowing the hazard or oxygen levels is extremely dangerous and likely insufficient.
Confined Space Rescue
A procedure for safely extracting individuals from confined spaces when an emergency occurs, emphasizing trained personnel and proper equipment.
- Do not attempt untrained rescue.
- Activate emergency plan immediately.
- Ensure rescuers are properly equipped and trained.
Memory trick: When a space is tight and a person is down, call the pros from your safety town.
