Approximately 60% of all fatalities happen to __________ in confined spaces.

• A. Assistants
• B. Supervisors
• C. Welders
• D. Inspectors

Answer: (A)

In confined-space safety, the greatest danger occurs when someone actually tries to enter the space. About 60% of fatalities happen to those who are attempting to enter or assist with entry—the would-be entrants—because they are directly exposed to the hazardous atmosphere inside, such as oxygen deficiency, toxic gases, or engulfment. The attendant stays outside to monitor and call for rescue, which helps protect others, and those not involved in entry (like supervisors, inspectors, or other workers) aren’t exposed to the same immediate risk. So the statistic reflects that the highest risk group is the assistants/entrants who attempt to work inside the confined space.
