Health Hazards Acute and Chronic:AIRBORNE EXPOSURE LIMITS (AEL): THE
PERMISSIBLE AIRBORNE EXPOS CONC FOR VX FOR 8-HR WORKDAY OF A 40-HR
WEEK IS AN 8-HR TWA OF 0.00001 MG/M3. THIS VALUE CAN BE FOUND IN

TO DATE, HOWEVER, OSHA HAS NOT PROMULGATED A PERMISSIBLE EXPOS CONC
FOR VX. DOSES WHICH ARE POTENTIALLY LIFE THREATENING MAY BE ONLY
SLIGHTLY LARGER THAN THOSE PRODUCING LEAST EFFECTS. DEATH USUALLY
OCCURS W/IN 15 MIN AFTER ABSORPTION OF A FATAL DOSAGE.

Effects of Overexposure:SYMPS OF OVEREXPOSURE MAY OCCUR W/IN MIN/HRS
DEPENDING UPON DOSE. THEY INCLUDE: MIOSIS (CONSTRICTION OF PUPILS)

EXPOSURE, SYMPTOMS PROGRESS TO CONVULSIONS & RESP FAILURE. VX IS A
LETHAL CHOLINESTERASE INHIBITOR.

First Aid:INHAL: HOLD BREATH TIL RESP PROT MASK IS DONNED. IF SEV SIGNS
OF AGENT EXPOS APPEAR (CHEST TIGHTENS, PUPIL CONSTRICTION,
INCOORDINATION ETC), IMMED ADMINISTER, IN RAPID SUCCESSION, ALL
THREE NERVE AGE NT ANTIDOTE KIT(S) MARK I INJECTORS (OR ATROPINE IF
DIRECTED BY MD). INJECTIONS USING THE MARK I KIT INJECTORS MAY BE
