Summarize the following:
A t-shirt can actually protect you from large particles, like dust or tear gas, though not perfectly. Try to create as perfect a seal as possible using both hands to keep the shirt over your nose and mouth.  Bandanas, towels, and blankets will provide similar protection in an emergency. A simple piece of fabric can save your life against ash and dust from a volcanic explosion. If you or someone you know feels light-headed, nauseous, or experiences seizures or loss of consciousness after inhaling a chemical, make a note of the chemical and call poison control immediately. In the U.S., poison control can be reached at the number 1-800-222-1222. If the victim is able to move, get them to fresh clean air as soon as possible. Stay away from the source of the chemicals. This is called the “recovery position.” Roll unconscious people on their sides, using their upper leg to brace them. Make sure their mouth faces down so that they can easily expel anything that comes up. Wait for emergency services and follow their directions.
Cover your nose and mouth with a t-shirt if you have no other protection. Call poison control immediately. Move immediately to fresh air. Turn unconscious victims on their side with their face down.
