===================== Hazards Identification =====================
LD50 LC50 Mixture:LC50 (INH,RAT):444 PPM(HYDROGEN SULFIDE)
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:TARGET ORGANS: RESPIRATORY SYSTEM,
BLOOD SYSTEM, CNS, CVS, REPRODUCTIVE SYSTEM, SKIN, EYES. ACUTE: DUE
TO SMALL SIZE OF INDIVIDUAL CYLINDER, NO UNUDUAL HEALTH EFFECTS ARE
ANTICIPATED UNDER ROUTINE USE . HOWEVER, HYDROGEN SULFIDE AND
CARBON MONOXIDE ARE TOXIC. OVER-EXPOSURE CAN CAUSE NAUSEA,
DIZZINESS, HEADACHE, COLLAPSE, UNCONSCIOUSNESS, COM AND DEATH.
HYDROGEN SULFIDE CAN IRRITATE SKIN AND EYES. S EVERE EYE
CONTAMINATION CAN RESULT IN BLINDNESS. CHRONIC: SEVERE OVEREXPOSURE
TO HYDROGEN SULFIDE, WHICH DO NOT RESULT IN DEATH, MAY CAUSE
LONG-TERM SYMPTOMS SUCH AS MEMORY LOSS, PARALYSIS, NERVE DAMA GE,
EYE DAMAGE.
Explanation of Carcinogenicity:THE COMPONENTS OF THIS GAS MIXTURE ARE
NOT CONSIDERED TO BE, NOR SUSPECTED TO BE, CANCER CAUSING AGENTS BY
OSHA, NTP, IARC AGENCIES.
Effects of Overexposure:HYDROGEN SULFIDE: ODOR IS UNPLEASANT. MAY BE
IRRITATING TO SKIN. INFLAMMATION AND IRRITATION OF EYES CAN OCCUR
AT VERY LOW AIRBORNE CONCENTRATION (<10PPM). OVER EXPOSURE MAY
CAUSE PAIN, BLURRING VISIO N, TEARING. DRYNESS AND IRRITATION OF
NOSE, THROAT, RESPIRATORY SYSTEM, HEADACHE, VOMITING, NAUSEA.
CARBON MONOXIDE: BRIGHT RED LIPS AND FINGERNAILS, HEADACHE,
PALPITATION OF HEART, MENTAL CONFUSION, NAUSEA, UNCONSCIOUSNESS.
CONCENTRATED OXYGEN: INCREASED BREATHING AND PULSE RATES, EMOTIONAL
UPSET, FATIGUE, DISTURBED RESPIRATION, NAUSEA, VOMITING, LOSS OF
CONSCIOUSNESS, COLLAPSE, DEATH.
Medical Cond Aggravated by Exposure:SKIN DISORDERS AND RESPIRATORY
CONDITIONS MAY BE AGGRAVATED BY REPEATED OVER-EXPOSURE TO THE
GASES. CARBON MONOXIDE CAN AGGRAVATE SOME DISEASES OF CARDIOVASCULR
SYSTEM (CORONARY ARTERY, ANGINA PECTORIS)
======================= First Aid Measures =======================
First Aid:RESCUERS SHOULD WEAR PERSONAL PROTECTIVE EQUIPMENT. AT A
MINIMUM, SELF-CONTAINED BREATHING APPARATUS MUST BE WORN. NO
UNUSUAL HEALTH EFFECTS ARE ANTICIPATED AFTER EXPOSURE TO THIS
PRODUCT, DUE TO SMAL L CYLINDER SIZE. IF ANY ADVERSE
SYMPTOMDEVELOPS, REMOVE VICTIM(S) QUICKLY TO FRESH AIR. TRAINED
PERSONNEL SHOULD GIVE OXYGEN AND/OR CPR IF NECESSARY. SKIN: IF
IRRITATION DEVELOPS, IMMEDIATELY BEGIN DE CONTAMINATION WITH
RUNNING WATER FOR 15 MINUTES. EYE: IF IRRITATION DEVELOPS, OPEN
VICTIM EYES WHILE UNDER GENTLE RUNNING WATER. MINIMUM FLUSHING IS
FOR 15 MINUTES. SEEK MEDICAL ASSISTANCE IMMEDIATLEY , PREFERABLY AN
OPHTHALMOLOGIST.
===================== Fire Fighting Measures =====================
Extinguishing Media:NON-FLAMMABLE GAS MIXTURE. USE EXTINGUISHING MEDIA
APPROPRIATE FOR SURROUNDING FIRE.
Fire Fighting Procedures:STRUCTURAL FIREFIGHTERS MUST WEAR
SELF-CONTAINED BREATHING APPARATUS AND FULL PROTECTIVE EQUIPMENT.
Unusual Fire/Explosion Hazard:THIS GAS MIXTURE CONTAINS TOXIC GASES,
HYDROGEN SULFIDE AND CARBON MONOXIDE AND PRESENTS AN HEALTH HAZARD
TO FIREFIGHTERS. THIS GAS MIXTURE IS NOT FLAMMABLE; HOWEVER,
CONTAINERS, WHEN INVOLVED IN FIRE , MAY RUPTURE OR BURST IN THE
HEAT OF THE FIRE.
================== Accidental Release Measures ==================
Spill Release Procedures:DUE TO THE SMALL SIZE AND CONTENT OF THE
CYLINDER, AN ACCIDENTAL RELEASE OF THIS PRODUCT PRESENTS
SIGNIFICANTLY LESS RISK OF OVER-EXPOSURE TO HYDROGEN SULFIDE AND
CARBON MONOXIDE THAN A SIMILAR RELEAS E FROM A LARGER CYLINDER.
HOWEVER, EXTREME CAUTION MUST BE USED. IN THE EVENT OF UNKNOWN
RELEASES TRAINED PERSONNEL SHOULD WEAR PROPER PROTECTIVE EQUIPMENT
AND USE PRE-PLANNED PROCEDURES. EVACUTE AREA
====================== Handling and Storage ======================
Handling and Storage Precautions:CYLINDERS SHOULD BE FIRMLY SECURED AND
KEPT AT ROOM TEMPERATURE (21C,70F). CYLINDERS SHOULD BE STORED IN
DRY, WELL-VENTILATED AREAS, AWAY FROM SOURCES OF HEAT, IGNITION AND
DIRECT SUNLIGHT. PROTECT CY LINDERS AGAINST PHYSICAL DAMAGE. FULL
AND EMPTY CYLINDERS SHOULD BE SEGREGATED.
Other Precautions:USE A FIRST-IN, FIRST-OUT SYSTEM. DO NOT REFILL DOT
39 CYLINDERS. COMPRESSED GASES CAN PRESENT SIGNIFICANT SAFETY
HAZARDS. DURING CYLINDER USE, USE EQUIPMENT DESIGNED FOR THESE
CYLINDERS. ENSURE ALL L INES AND EQUIPMENT ARE RATED FOR PROPER
SERVICE PRESSURE. THESE CYLINDERS ARE NOT REFILLABLE.
============= Exposure Controls/Personal Protection =============
Respiratory Protection:NO SPECIAL RESPIRATORY PROTECTION IS REQUIRED
UNDER NORMAL CIRCUMSTANCES OF USE. USE SUPPLIED AIR RESPIRATORY
PROTECTION IF CARBON MONOXIDE LEVELS EXCEED THE EXPOSURE LEVELS OR
IF OXYGEN LEVELS ARE BE LOW 19.5%, OR IF EITHER LEVEL IS UNKNOWN
DURING EMERGENCY RESPONSE TO A RELEASE OF THIS PRODUCT. FOLLOW OSHA
REGISTRY PROTECTION STANDARD (29 CFR 1910.134).
Ventilation:NO SPECIAL VENTILATION SYSTEMS OR ENGINEERING CONTROLS ARE
NEEDED UNDER NORMAL CIRCUMSTANCES OF USE.AS WITH ALL CHEMICALS, USE
PRODUCT IN WELL-VENTILATED AREAS.
Protective Gloves:NO SPECIAL PROTECTION NEEDED UNDER NORMAL
CIRCUMSTANCES OF USE.
Eye Protection:SAFETY GLASSES
Other Protective Equipment:BODY PROTECTION: NO SPECIAL PROTECTION IS
NEEDED UNDER NORMAL CIRCUMSTANCES OF USE.
Work Hygienic Practices:GAS MASK WITH CANISTER TO PROTECT AGAINST
CARBON MONOXIDE; OR ESCAPE-TYPE SCBA. NOTE: END OF SERVICE LIFE
