What should you do if the line of the roof is spongy during operations?

When the roof feels spongy during operations, this is a significant indicator of potential structural compromise. A spongy roof suggests that there may be water damage or weakening materials, which can lead to a collapse if not addressed appropriately. The safety of all personnel must be the top priority in such situations.

Evacuating the area allows for a safe distance from possible hazards. It also facilitates an assessment of the situation by qualified personnel who can evaluate the risk and make informed decisions about whether it is safe to continue operations or if additional precautions are needed.

Other options, such as continuing operations or encouraging personnel to stay inside, pose substantial risks and can lead to serious injuries or fatalities. Requesting additional equipment may be sensible in some contexts, but it does not address the immediate danger posed by a compromised roof. The focus should be on ensuring everyone's safety first and foremost.
