| 4. FIRST AID MEASURES | |
DESCRIPTION OF FIRST AID MEASURES:
GENERAL ADVICE:
SHOW THIS SAFETY DATA SHEET TO THE DOCTOR IN ATTENDANCE. IMMEDIATE MEDICAL
ATTENTION IS REQUIRED.
INHALATION:
REMOVE TO FRESH AIR AND KEEP COMFORTABLE FOR BREATHING. IF BREATHING IS
DIFFICULT, GIVE OXYGEN. IF BREATHING HAS STOPPED, GIVE ARTIFICIAL
RESPIRATION. GET MEDICAL ATTENTION IMMEDIATELY.
SKIN CONTACT:
WASH OFF IMMEDIATELY WITH PLENTY OF WATER. FOR DERMAL CONTACT OR SUSPECTED
FROSTBITE, REMOVE CONTAMINATED CLOTHING AND FLUSH AFFECTED AREAS WITH
LUKEWARM WATER. DO NOT USE HOT WATER. A PHYSICIAN SHOULD SEE THE PATIENT
PROMPTLY IF CONTACT WITH THE PRODUCT HAS RESULTED IN BLISTERING OF THE
DERMAL SURFACE OR IN DEEP TISSUE FREEZING.
EYE CONTACT:
RINSE IMMEDIATELY WITH PLENTY OF WATER, ALSO UNDER THE EYELIDS, FOR AT
LEAST 15 MINUTES. IF FROSTBITE IS SUSPECTED, FLUSH EYES WITH COOL WATER FOR
15 MINUTES AND OBTAIN IMMEDIATE MEDICAL ATTENTION.
INGESTION: NOT AN EXPECTED ROUTE OF EXPOSURE.
SELF-PROTECTION OF THE FIRST AIDER:
REMOVE ALL SOURCES OF IGNITION. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH
SELF-CONTAINED BREATHING APPARATUS. ENSURE THAT MEDICAL PERSONNEL ARE AWARE
OF THE MATERIAL(S) INVOLVED AND TAKE PRECAUTIONS TO PROTECT THEMSELVES.
MOST IMPORTANT SYMPTOMS AND EFFECTS, BOTH ACUTE AND DELAYED:
SYMPTOMS:
MAY CAUSE CENTRAL NERVOUS SYSTEM EFFECTS SUCH AS HEADACHE, DIZZINESS, LOSS
OF BALANCE AND COORDINATION, UNCONSCIOUSNESS, COMA, RESPIRATORY FAILURE AND
DEATH. HYDROGEN SULFIDE GAS BETWEEN 15 AND 500 PPM CAN CAUSE HEADACHE,
NAUSEA AND DIZZINESS. CONTINUED EXPOSURE AT THESE LEVELS CAN LEAD TO LOSS
OF REASONING AND BALANCE, DIFFICULTY IN BREATHING, FLUID IN THE LUNGS, AND
POSSIBLE LOSS OF CONSCIOUSNESS. GREATER THAN 500 PPM CAN CAUSE RAPID
UNCONSCIOUSNESS DUE TO RESPIRATORY PARALYSIS AND DEATH BY SUFFOCATION.
GREATER THAN 1000 PPM CAN CAUSE IMMEDIATE UNCONSCIOUSNESS AND DEATH IF NOT
PROMPTLY REVIVED. IRRITATING TO EYES, RESPIRATORY SYSTEM AND SKIN. SYMPTOMS
MAY BE DELAYED.
INDICATION OF ANY IMMEDIATE MEDICAL ATTENTION AND SPECIAL TREATMENT NEEDED:
NOTE TO PHYSICIANS:
ACUTE HYDROGEN SULFIDE POISONING CAN BE TREATED BY INDUCTION OF
METHEMOGLOBINEMIA THROUGH PARENTERAL INJECTION OF METHEMOGLOBIN GENERATING
AGENTS (SODIUM NITRILE). THIS ACTS AN ANTIDOTE BY RESTORING THE NORMAL
ACTIVITY OF THE SULFIDE INHIBITED ENZYME.
| 5. FIRE-FIGHTING MEASURES | |
SUITABLE EXTINGUISHING MEDIA:
DRY CHEMICAL OR CO2. WATER SPRAY (FOG). DO NOT EXTINGUISH A LEAKING GAS
FIRE UNLESS LEAK CAN BE STOPPED.
SPECIFIC EXTINGUISHING METHODS:
IF POSSIBLE, STOP THE FLOW OF GAS. DO NOT EXTINGUISH THE FIRE UNTIL SUPPLY
IS SHUT OFF AS OTHERWISE AN EXPLOSIVE-IGNITION MAY OCCUR. IF THE FIRE IS
EXTINGUISHED AND THE FLOW OF GAS CONTINUES, USE INCREASED VENTILATION TO
PREVENT BUILD-UP OF EXPLOSIVE ATMOSPHERE. VENTILATION FANS MUST BE
EXPLOSION PROOF. USE NON-SPARKING TOOLS TO CLOSE CONTAINER VALVES.
USE WATER SPRAY TO COOL SURROUNDING CONTAINERS. BE CAUTIOUS OF A BOILING
LIQUID EVAPORATING VAPOR EXPLOSION, BLEVE, IF FLAME IS IMPINGING ON
SURROUNDING CONTAINERS. FOR MASSIVE FIRE, USE UNMANNED HOSE HOLDERS OR
MONITOR NOZZLES; IF THIS IS IMPOSSIBLE WITHDRAW FROM AREA AND LET FIRE
BURN. DAMAGED CYLINDERS SHOULD BE HANDLED ONLY BY SPECIALISTS.
SPECIFIC HAZARDS ARISING FROM THE CHEMICAL:
EXTREMELY FLAMMABLE GAS. MAY FORM EXPLOSIVE MIXTURES WITH AIR. WILL BE
EASILY IGNITED BY HEAT, SPARKS OR FLAMES. VAPORS MAY TRAVEL TO SOURCE OF
IGNITION AND FLASH BACK. VAPORS FROM LIQUEFIED GAS ARE INITIALLY HEAVIER
THAN AIR AND SPREAD ALONG GROUND. VAPORS MAY ACCUMULATE IN CONFINED AREAS
(BASEMENT, TANKS, HOPPER/TANK CARS, ETC.). CYLINDERS MAY RUPTURE UNDER
EXTREME HEAT.
HAZARDOUS COMBUSTION PRODUCTS: SULFUR OXIDES.
PROTECTIVE EQUIPMENT AND PRECAUTIONS FOR FIREFIGHTERS:
AS IN ANY FIRE, WEAR SELF-CONTAINED BREATHING APPARATUS PRESSURE-DEMAND,
NIOSH (APPROVED OR EQUIVALENT) AND FULL PROTECTIVE GEAR. AS AN IMMEDIATE
PRECAUTIONARY MEASURE, ISOLATE SPILL OR LEAK AREA FOR AT LEAST 100 METERS
(330 FEET) IN ALL DIRECTIONS. ADDITIONAL CHEMICAL PROTECTIVE CLOTHING MAY
BE REQUIRED TO PROTECT FROM TOXIC DECOMPOSITION PRODUCTS.
| 6. ACCIDENTAL RELEASE MEASURES | |
PERSONAL PRECAUTIONS, PROTECTIVE EQUIPMENT AND EMERGENCY PROCEDURES:
PERSONAL PRECAUTIONS:
ELIMINATE ALL IGNITION SOURCES (NO SMOKING, FLARES, SPARKS OR FLAMES IN
IMMEDIATE AREA). EVACUATE PERSONNEL TO SAFE AREAS. KEEP PEOPLE AWAY FROM
AND UPWIND OF SPILL/LEAK. ENSURE ADEQUATE VENTILATION, ESPECIALLY IN
CONFINED AREAS. MONITOR CONCENTRATION OF RELEASED PRODUCT. CONSIDER THE
RISK OF POTENTIALLY EXPLOSIVE ATMOSPHERES. ALL EQUIPMENT USED WHEN HANDLING
THE PRODUCT MUST BE GROUNDED. USE NON-SPARKING TOOLS AND EQUIPMENT. USE
PERSONAL PROTECTION RECOMMENDED IN SECTION 8. WEAR SELF-CONTAINED BREATHING
APPARATUS WHEN ENTERING AREA UNLESS ATMOSPHERE IS PROVED TO BE SAFE.
OTHER INFORMATION:
GAS/VAPOR IS HEAVIER THAN AIR. PREVENT FROM ENTERING SEWERS, BASEMENTS AND
WORKPITS, OR ANY PLACE WHERE ACCUMULATION MAY BE DANGEROUS.
ENVIRONMENTAL PRECAUTIONS:
ENVIRONMENTAL PRECAUTIONS:
PREVENT SPREADING OF VAPORS THROUGH SEWERS, VENTILATION SYSTEMS AND
CONFINED AREAS.
METHODS AND MATERIAL FOR CONTAINMENT AND CLEANING UP:
METHODS FOR CONTAINMENT:
STOP THE FLOW OF GAS OR REMOVE CYLINDER TO OUTDOOR LOCATION IF THIS CAN BE
DONE WITHOUT RISK. IF LEAK IS IN CONTAINER OR CONTAINER VALVE, CONTACT THE
APPROPRIATE EMERGENCY TELEPHONE NUMBER IN SECTION 1 OR CALL YOUR CLOSEST
LINDE LOCATION.
METHODS FOR CLEANING UP:
RETURN CYLINDER TO LINDE OR AN AUTHORIZED DISTRIBUTOR.
| 7. HANDLING AND STORAGE | |
PRECAUTIONS FOR SAFE HANDLING:
ADVICE ON SAFE HANDLING:
DO NOT RELY ON THE OLFACTORY SENSE TO DETECT THE PRESENCE OF HYDROGEN
SULFIDE. ANALYTICAL DEVICES AND INSTRUMENTATION ARE READILY AVAILABLE FOR
THIS PURPOSE. PERFORM FREQUENT TESTS TO BE CERTAIN THAT THE EXPOSURE LIMITS
ARE NOT EXCEEDED. MANY METALS CORRODE RAPIDLY WITH WET HYDROGEN SULFIDE.
ANHYDROUS HYDROGEN SULFIDE CAN BE HANDLED IN CARBON STEEL, ALUMINUM
INCONEL(R*), STELLITE(R*), AND 304 ND 316 STAINLESS STEELS. AVOID HARD
STEELS WHICH ARE HIGHLY STRESSED SINCE THEY MAY BE SUSCEPTIBLE TO HYDROGEN
EMBRITTLEMENT FROM HYDROGEN SULFIDE. AUTOMATED MULTI-POINT AIR SAMPLERS
WITH ALARMS FOR PLANT PRODUCTION UNITS SHOULD BE PROVIDED TO CONSTANTLY
MONITOR THE AIR IN AND AROUND UNITS. KEEP AWAY FROM HEAT, HOT SURFACES,
SPARKS, OPEN FLAMES AND OTHER IGNITION SOURCES. NO SMOKING. GROUND AND
BOND ALL LINES AND EQUIPMENT ASSOCIATED WITH PRODUCT SYSTEM. ALL EQUIPMENT
SHOULD BE NON-SPARKING AND EXPLOSION PROOF. SEPARATE FLAMMABLE GAS
CYLINDERS FROM OXYGEN AND OTHER OXIDIZERS BY A MINIMUM DISTANCE OF 20 FT.
OR BY A 5 FT. HIGH BARRIER WITH A MINIMUM FIRE RESISTANCE RATING OF A HALF
AN HOUR. "NO SMOKING" SIGNS SHOULD BE POSTED IN STORAGE AND USE AREAS.
WHEN MOVING CYLINDERS, EVEN FOR SHORT DISTANCE, USE A CART DESIGNED TO
TRANSPORT CYLINDERS. PROTECT CYLINDERS FROM PHYSICAL DAMAGE; DO NOT DRAG,
ROLL, SLIDE OR DROP. NEVER ATTEMPT TO LIFT A CYLINDER BY ITS VALVE
PROTECTION CAP. USE A BACKFLOW PREVENTIVE DEVICE IN PIPING. NEVER INSERT AN
OBJECT (E.G. WRENCH, SCREWDRIVER, PRY BAR, ETC.) INTO VALVE CAP OPENINGS.
DOING SO MAY DAMAGE VALVE, CAUSING LEAK TO OCCUR. USE AN ADJUSTABLE STRAP
WRENCH TO REMOVE OVER-TIGHT OR RUSTED CAPS. USE ONLY WITH ADEQUATE
VENTILATION. USE ONLY WITH EQUIPMENT RATED FOR CYLINDER PRESSURE. CLOSE
VALVE AFTER EACH USE AND WHEN EMPTY. IF USER EXPERIENCES ANY DIFFICULTY
OPERATING CYLINDER VALVE DISCONTINUE USE AND CONTACT SUPPLIER. ENSURE THE
COMPLETE GAS SYSTEM HAS BEEN CHECKED FOR LEAKS BEFORE USE.
NEVER PUT CYLINDERS INTO TRUNKS OF CARS OR UNVENTILATED AREAS OF PASSENGER
VEHICLES. NEVER ATTEMPT TO REFILL A COMPRESSED GAS CYLINDER WITHOUT THE
OWNER'S WRITTEN CONSENT. NEVER STRIKE AN ARC ON A COMPRESSED GAS CYLINDER
OR MAKE A CYLINDER A PART OF AN ELECTRICAL CIRCUIT.
ONLY EXPERIENCED AND PROPERLY INSTRUCTED PERSONS SHOULD HANDLE GASES UNDER
PRESSURE. ALWAYS STORE AND HANDLE COMPRESSED GAS CYLINDERS IN ACCORDANCE
WITH COMPRESSED GAS ASSOCIATION, PAMPHLET CGA-P1, SAFE HANDLING OF
COMPRESSED GASES IN CONTAINERS.
FOR ADDITIONAL RECOMMENDATIONS, CONSULT COMPRESSED GAS ASSOCIATION'S
PAMPHLET G-12.
CONDITIONS FOR SAFE STORAGE, INCLUDING ANY INCOMPATIBILITIES:
STORAGE CONDITIONS:
STORE IN COOL, DRY, WELL-VENTILATED AREA OF NON-COMBUSTIBLE CONSTRUCTION
AWAY FROM HEAVILY TRAFFICKED AREAS AND EMERGENCY EXITS. KEEP AT
TEMPERATURES BELOW 52 DEG. C / 125 DEG. F. CYLINDERS SHOULD BE STORED
UPRIGHT WITH VALVE PROTECTION CAP IN PLACE AND FIRMLY SECURED TO PREVENT
FALLING. FULL AND EMPTY CYLINDERS SHOULD BE SEGREGATED. USE A "FIRST
IN-FIRST OUT" INVENTORY SYSTEM TO PREVENT FULL CYLINDERS FROM BEING STORED
FOR EXCESSIVE PERIODS OF TIME. STORED CONTAINERS SHOULD BE PERIODICALLY
CHECKED FOR GENERAL CONDITION AND LEAKAGE. OUTSIDE OR DETACHED STORAGE IS
PREFERRED.
INCOMPATIBLE MATERIALS: OXIDIZING AGENTS. NITRIC ACID.
