First Aid:INHALATION: REMOVE THE VICTIM FROM EXPOSURE. APPLY ARTIFICIAL
RESPIRATION IF THE VICTIM ISN'T BREATHING. DON'T USE MOUTH-TO-MOUTH
RESUSCITATION. THIS INTERRUPTED APPLICATION OF AMYL NITRITE IS
IMPORTA NT AS CONTINUOUS APPLICATION MAY PREVENT ADEQUATE
OXYGENATION. REPEAT APPLICATION 5 TIMES AT 15 SECOND INTERVALS. USE
A FRESH PEARL EVERY 5 MINS UNTIL 3 OR FOUR PEARLS HAVE BEEN USED.
===================== Fire Fighting Measures =====================
Extinguishing Media:THIS GAS MIXTURE ISN'T FLAMMABLE. USE MEDIA
APPROPRIATE FOR SURROUNDING FIRE.

Other Precautions:AVOID BREATHING GAS. AVOID CONTACT W/SKIN. USE IN
WELL VENTILATED AREAS. WEAR IMPERVIOUS GLOVES TO AVOID SKIN
EXPOSURE WHILE CRUSHING AMPOULES IN HOOD.
Respiratory Protection:DUE TO THE LIMITED AMOUNT OF HYDROGEN CYANIDE IN
AN AMPOULE & THE LOW RELEASE RATE EMPLOYED IN INSTRUMENT
CALIBRATION, RESPIRATORY PROTECTION ISN'T INDICATED UNDER
CONDITIONS OF INTENDED USE.
Ventilation:CRUSH AMPOULES INDIVIDUALLY IN AN EXHAUST HOOD EQUIPPED TO
ASPIRATE AIR AT A FACE VELOCITY OF 100FT/MIN OR GREATER.
Supplemental Safety and Health
