Which of the following is NOT considered a preventive measure in explosion risk management?

The option you identified is not considered a preventive measure in explosion risk management because encouraging improper handling of materials directly contradicts safety practices and increases the risk of accidents. Preventive measures are actions taken to minimize the chances of an explosion occurring, and promoting incorrect handling behaviors can lead to unsafe conditions and practices that heighten the likelihood of an explosion.

Conversely, training staff on safety protocols, conducting regular equipment maintenance, and adhering to established safety guidelines are all critical components of a robust explosion risk management strategy. These measures help ensure that personnel are aware of safety procedures, that equipment is functioning correctly and safely, and that all operations follow best practices designed to prevent explosive incidents.
