Get medical attention immediately. Remove victim to fresh air and keep at rest in a
position comfortable for breathing. If it is suspected that fumes are still present, the
rescuer should wear an appropriate mask or self-contained breathing apparatus. If
not breathing, if breathing is irregular or if respiratory arrest occurs, provide artificial
respiration or oxygen by trained personnel. It may be dangerous to the person
providing aid to give mouth-to-mouth resuscitation. If unconscious, place in recovery
position and get medical attention immediately. Maintain an open airway. Loosen
tight clothing such as a collar, tie, belt or waistband. In a case of inhalation of
decomposition products in a fire, symptoms may be delayed. The exposed person
may need to be kept under medical surveillance for 48 hours.
