Personal Injuries Involving Fires When a person’s clothing is on fire, you may need to lead him or her to the safety shower. Some people instinctively run randomly if their clothes are on fire, which fans the flames and increases their injuries. If possible, stop an individual from running. If the shower is not readily available, douse the individual with water. Get him or her to stop, drop, and roll; that is, to lie down and roll to put out the fire. Then, try to extinguish any small, still-burning flames by patting them out. Beat out the flames around the head and shoulders, then work downward toward the feet. Next, cover the victim with a coat, blanket, or whatever is available but leave the head uncovered. Do not use fire blankets until the fire is extinguished.8 While wearing gloves if necessary, remove any clothing contaminated with chemicals. To prevent contamination of the eyes, use scissors when removing pullover shirts or sweaters. Place clean, wet, cold cloths on burned areas. Wrap the victim to avoid shock and exposure. Get medical attention promptly. 8If the victim is standing, wrapping the body with a fire blanket or other material can force flames toward the face and neck and, if wrapped tightly, can press melted globs of what once was polymeric clothing fabric into the flesh, thereby accentuating the severity of injury to the victim. 34 students short index 1/15/03 12:45 PM Page 35 Chemicals on Skin, Clothing, and Eyes For small liquid spills that only affect a small area of skin, immediately flush with flowing water for at least 15 minutes. Remove any jewelry to facilitate removal of possible residual liquid. If there is no visible injury, wash the entire area with warm water and soap. Check the MSDS to see whether any delayed effects should be expected. It is advisable to seek medical attention for even minor chemical burns. Hydrofluoric acid spills require special treatment; see “Acids and Bases” on page 22. Solid chemicals that are spilled on the ski...
