Question: A plumber prepares to enter a confined space for a routine valve inspection. The entry permit has been completed, atmospheric testing confirmed safe oxygen levels and no hazardous gases, and a standby person is in position with communication equipment. Just before entry, the standby person notices that the plumber's safety harness has a fray in one of the primary load-bearing straps. What action should be taken?

Answer options: ✅ The plumber should not enter; the harness must be replaced or repaired by a qualified person before use.

• The plumber can enter, but the standby person should maintain closer vigilance.
• The fray is minor; the plumber can wrap it with electrical tape and proceed with entry.
• The plumber can proceed if they use an alternative anchorage point for the lifelilne.

Correct answer: The plumber should not enter; the harness must be replaced or repaired by a qualified person before use.

Explanation: Any damage, such as a fray, to a primary load-bearing strap of a safety harness compromises its integrity and renders it unsafe for use. Safety equipment must be in good working order. The plumber must not enter the confined space until the harness is replaced or properly repaired by a qualified person, as per manufacturer specifications and safety regulations.
