Water reactive material classes should NOT use an Explosive symbol?

Water reactive materials should not use an explosive symbol because their primary hazard is not related to detonation or explosive reactions, but rather to their violent reaction with water, which can produce toxic gases or heat. The explosive symbol implies a risk of detonation under specific conditions, whereas water reactive materials pose risks primarily through chemical reactions with moisture. Proper labeling should reflect the specific hazards associated with these materials to ensure safe handling and transportation.
