First-degree bums

Toxicity of EtnO (Ref 17, pp 314—15 Spec MIL-E-52171). Liquid EtnO, concentrated or dilute, when exposed to the skin can cause -severe delayed bums. Short exposures produce mild first degree bums, but prolonged exposures produce second degree bums with the formation of large blisters. Exposure to the vapor results in systemic manifestations and irritation to the respiratory system. Inhalation of ethylene oxide vapors, if. prolonged, results in severe systemic poisoning with the symptoms of nausea, vomiting, headache, dysnea, and diarthea. The anesthetic properties are similar to chloroform, but with pronounced undesirable side and after effects. 

Superficial (first-degree bum) The epidermis is red, painful, dry, and no blisters (i.e., sun bum). Superficial bums are treated by removing clothing at the bum site and placing a cold wet compress on the bum site to constrict blood vessels, reducing swelling and pain. Superficial bums should be treated with antibiotics such as Bacitracin with polymyxin B (Polysporin) and similar over-the-counter (OTC) antibiotics.
