 COULD RESULT IN LOSS OF CONSC AND     POSSIBLY DEATH IN 30 MIN. EXPOSURE
 TO H2S 700-1990 PPM RESULTS IN A RAPID LOSS OF CONSC, RESP FAILURE
 AND DEATH. HIGH CONCS CAUSE BRONCHITIS, PULMONARY EDEMA AND
 PARALYSIS OF THE RESPIRATORY SYSTEM AND ASPHYXIATION. STUPOR AND
 UNCONSCIOUSNESS MAY BE FIRST SIGNS OF EXCESSIVE EXPOSURE (IE H2S>230
 PPM) BECAUSE OF EFFECTS ON CENTRAL NERVOUS SYSTEM. H2S CAN ALSO CAUSE
 PAINFUL CONJUNCTXVITXS. CORNEAL EROSION, AND SPASM OF EYE-LIDS.
