Magazine and salvage hazards in sunken warships

Are dangerous magazines unique to SS Richard Montgomery, or are other sunken warships also hazardous?

Every sunken magazine deserves caution because unexploded ordnance may remain active, while salvage can disturb explosives and desecrate war graves.

The danger is not limited to SS Richard Montgomery. Every sunken magazine may remain an explosive hazard, alongside the obligation to respect war graves. Commercial recovery of pre-nuclear steel can tear apart wrecks containing human remains. It may also disturb old explosives, exposing salvors and the wreck site to avoidable danger.
