Health Hazards Acute and Chronic:TARGET ORGANS: EYES, SKIN AND
RESPIRATORY PASSAGES. EYES-MAY CAUSE IRRITATION. DUST IS AN EYE AND
RESPIRATORY IRRITANT AND CAN CAUSE SKIN BURNS. THE EFFECTS OF
CALCIUM CARBIDE ARE LIMITED TO LOCAL AC TION AT THE SITE OF
CONTACT WITH A MOIST SURFACE. THE RESIDUAL LIME ACTS AS AN IRRITANT
AND FIRST AID IS DIRECTED TOWARD REMOVAL OF IRRITANT. DRY POWDER
REACTS WITH BODY MOISTURE TO FORM ALKALI WHICH IRRITATES THE SKIN,
EYES AND RESPIRATORY PASSAGES. SKIN-MAY CAUSE IRRITATION.
INGESTION-MAY CAUSE GASTROINTESTINAL DISCOMFORT. INHALATION-MAY
CAUSE IRRITATION TO RESPIRATORY TRACT.
Effects of Overexposure:TARGET ORGANS: EYES, SKIN AND RESPIRATORY
PASSAGES. EYES-MAY CAUSE IRRITATION. DUST IS AN EYE AND RESPIRATORY
IRRITANT AND CAN CAUSE SKIN BURNS. THE EFFECTS OF CALCIUM CARBIDE
ARE LIMITED TO LOCAL AC TION AT THE SITE OF CONTACT WITH A MOIST
SURFACE. THE RESIDUAL LIME ACTS AS AN IRRITANT AND FIRST AID IS
DIRECTED TOWARD REMOVAL OF IRRITANT. DRY POWDER REACTS WITH BODY
MOISTURE TO FORM ALKALI WHICH IRRITATES THE SKIN, EYES AND
RESPIRATORY PASSAGES. SKIN-MAY CAUSE IRRITATION. INGESTION-MAY
CAUSE GASTROINTESTINAL DISCOMFORT. INHALATION-MAY CAUSE IRRITATION
TO RESPIRATORY TRACT.
Medical Cond Aggravated by Exposure:PREEXISTING CONDITIONS OF THE EYES,
SKIN AND RESPIRATORY PASSAGES.

First Aid:EYES: FLUSH WITH WATER FOR 15 MINUTES, RAISING AND LOWERING
EYELIDS OCCASIONALLY. GET MEDICAL ATTENTION. SKIN: THOROUGHLY WASH
EXPOSED AREA FOR 15 MINUTES. REMOVE CONTAMINATED CLOTHING. LAUNDER
CONTAM INATED CLOTHING BEFORE RESUE. GET MEDICAL ATTENTION IF
IRRITATION PERSISTS. INGESTION: IF SWALLOWED, IF CONSCIOUS, GIVE
PLENTY OF WATER. IMMEDIATELY CALL A PHYSICIAN OR POISON CONTROL
CENTER. NEVER G IVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON.
INHALATION: REMOVE TO FRESH AIR. GIVE OXYGEN IF BREATHING IS
DIFFICULT; GIVE ARTIFICIAL RESPIRATION IF BREATHING HAS STOPPED.
KEEP PERSON WARM, QUIET, A ND GET MEDICAL ATTENTION.

OR SCOOP UP AND CONTAINERIZE FOR DISPOSAL.

Handling and Storage Precautions:PROTECT AGAINST PHYSICAL DAMAGE. STORE
IN DRY, NON-COMBUSTIBLE, WELL-VENTILATED PLACE WITHOUT SPRINKLER
PROTECTION. EXCLUDE POSSIBLE SOURCES OF IGNITION OF ACETYLENE GAS
ISOLATE FROM OTHER MATERIALS. WASH THOROUGHLY AFTER HANDLING.
Other Precautions:GROUNDING OF CALCIUM CARBIDE CONTAINERS TO PREVENT
STATIC ELECTRICITY DISCHARGE IS RECOMMENDED. COPPER GROUND STRAP OR
CABLE SHOULD NOT BE USED. REMOVE AND WASH CONTAMINATED CLOTHING.

Respiratory Protection:NONE NEEDED UNDER NORMAL CONDITIONS OF USE WITH
ADEQUATE VENTILATION. NIOSH APPROVED EQUIPMENT SHOULD BE WORN IF
PELS ARE EXCEEDED.

Protective Gloves:RUBBER, NEOPRENE, PVC, OR EQUIVALENT.
Eye Protection:SPLASH PROOF CHEMICAL SAFETY GOGGLES AT ALL TIMES.
Other Protective Equipment:LAB COAT, EYE WASH, SAFETY SHOWER.
Work Hygienic Practices:LAUNDER CONTAMINATED CLOTHING BEFORE RESUE.
Supplemental Safety and Health
EXPLOSION HAZARDS: NOT FLAMMABLE IN DRY STATE BUT PRODUCES ACETYLENE
GAS ON CONTACT WITH WATER OR MOISTURE.WILL GENERATE SUFFICIENT HEAT
ON CONTACT WITH SMALL AMOUNTS OF WATER TO IGNITE THE ACETYLENE GAS
FORMED; FIRE FROM WET CARBIDE SHOULD NOT BE EXTINGUISHED,SINCE
UNBURNED ACETYLENE MAY POCKET & EXPLODE IF IGNITED.
