If drums and containers appear to be under pressure, what action should be taken?

If drums and containers appear to be under pressure, the most prudent action is to refrain from moving them until the cause of the pressure is clearly identified. This approach prioritizes safety, as pressured containers could potentially be hazardous and may lead to leaks, ruptures, or explosions when disturbed. Identification of the source of pressure is crucial in managing the situation effectively and preventing an accidental release of hazardous materials.

Engaging in any of the other options without proper analysis may increase the risk involved. For instance, implementing containment procedures without understanding the pressure source might not address the root problem effectively, and venting the drums could inadvertently create a dangerous situation by releasing toxic fumes or flammable substances.

Therefore, ensuring a complete assessment of the situation before taking any action is essential in maintaining safe practices when dealing with pressurized drums and containers.
