EMERGENCY AND FIRST AID PROCEDURES

  • INHALATION: Hold breath until respiratory protective mask is put on. If severe signs of agent exposure appear immediately administer, in rapid succession, all three Nerve Agent Antidote Kit(s), Mark I injectors, or atropine if directed by a local caregiver. Some of these signs are chest tightening, pupil constriction, and incoordination. Injections using the Mark I kit injectors may be repeated in 5 to 20 minute intervals if signs and symptoms are progressing. Do this until three series of injections have been administered. No more injections will be given unless directed by medical personnel. A record will be maintained of all injections given. If breathing has stopped, give artificial respiration. Mouth-to-mouth resuscitation should be used when approved mask-bag of oxygen delivery systems are not available. Do not use mouth-to-mouth resuscitation when facial contamination exists. If breathing is difficult, administer oxygen. Seek medical attention immediately.

  • EYE CONTACT: IMMEDIATELY flush eyes with water for 10-15 minutes. Then put on respiratory protective mask. Although miosis (pinpointing of the pupils) may be an early sign of agent exposure, an injection will not be given when miosis is the only sign present. Instead the individual will be taken immediately to a medical treatment area for observation.

  • SKIN CONTACT: Put on a respiratory protective mask and remove contaminated clothing. Immediately wash contaminated skin with large amounts of soap and water, 10% sodium carbonate solution, or 5% liquid household bleach. Rinse well with water to remove decontaminant. Administer nerve agent antidote kit, Mark I only if local sweating and muscular twitching symptoms are present. Seek medical attention immediately.

  • INGESTION: Do not induce vomiting. First symptoms are likely to be gastrointestinal. Immediately administer Nerve Agent Antidote kit, Mark I. Seek medical attention immediately.
