Bruising and Bleeding. Bruising or bleeding after an injury is normal. However, some people have disorders that cause them to bruise or bleed too easily. Sometimes people bleed without any obvious triggering event or injury.
The skin of victims of mustard gas blistered, the eyes became very sore and they began to vomit. Mustard gas caused internal and external bleeding and attacked the bronchial tubes, stripping off the mucous membrane. This was extremely painful and most soldiers had to be strapped to their beds.
Itâs estimated that as many as 85% of the 91,000 deaths attributed to gas in World War 1 were a result of phosgene or the similar agent diphosgene. Itâs hard to put a precise number on, since it was commonly used in combination with chlorine gas, along with the related chemical diphosgene.
