How often should a hot air lay-up installation be inspected?

The correct choice specifies that a hot air lay-up installation should be inspected at the start of each shift. This frequency of inspection is essential because hot air lay-ups are often utilized in applications where equipment may be subject to significant temperature changes, pressure variations, or other operational stresses. Inspections at the beginning of each shift ensure that any potential issues can be caught early before they affect the operation.

Start-of-shift inspections also help in verifying that safety measures are in place, that equipment is functioning as intended, and that any changes in conditions from the previous shift are monitored. This proactive approach minimizes risks and downtime, ultimately maintaining operational efficiency and safety.

Other options suggest less frequent or random checks, which may not adequately address potential problems that could develop between shifts. Regular inspections at a defined cadence like at shift starts are crucial for maintaining the integrity of the equipment and ensuring safety in operations.
