         Moderate. worsening of the above, particularly in lung effects.
           ybe beginning of a feeling of generalized weakness due to
         s@eletal    muscle    involvement,     perhaps    with     generalized
         fasciculations, generalized twitching of large muscle groups,
                  testinal involvement with nausea, vomiting, diarrhea

                   Loss of consciousness, convulsions (seizures), muscular
                   and finally flaccid paralysis, cessation of respiration
         (see below), and death

         Time course: The above have occurred in humans after one breath,
         within seconds of exposure of a large amount of agent           vapor,
         Again, effects do not worsen appreciably after several minutes
         after removal from agent.       Onset time of effects after vapor
         e@osare is within seconds to several minutes.
           I
         SFIN (PERCUTANEOUS) EXPOSURE
         It is more difficult to separate this type of exposure into
         4tegories; effects are more likely to be progressive due to
         continued absorption of agent in the skin layers.
         In general: effects may occur within minutes of exposure (after
         stvaral LD..'s) to 18 hours later; the later the onset time the
         Ilms likel@ the agent is to produce lethality.
         Effects may occur hours after the skin has been decontaminated

         M@ld effects, initial effects, or effects from a small amount:
         Localized sweating at the exposure site and possibly muscle
         twitching (fasciculations) at the site
           I
         Mgderate    effects   or    first   systemic    effects        usually
         gastrointestinal, with nausea, vomiting, diarrhea; may be feeling
         of generalized muscular weakness, generalized fasciculations or
         t*it@ng.

         Severe effects:      Sudden loss of consciousness and collapse,
ns (seizures), latermuscularweakness, flaccidparalysis,
         cczssation of respiration
           i
         Time course: The larger the exposure, the shorter the onset time.
         After a large exposure (a lethal amount or greater) effects may
         ogcur within minutes and after an asymptomatic period the first
         effect may be loss of consciousness. The onset time may be as long
         as 18 hours after exposure, but this is usually after a non-lethal
         amount and the effects usually are not lethal.
         N@E:    Miosis is usually not an early effect from paroutancous
         e7osure; generally iniosis is a direct effect of vapor in the eye.
