| 4. FIRST AID MEASURES | |
DESCRIPTION OF FIRST AID MEASURES:
GENERAL ADVICE: SHOW THIS SAFETY DATA SHEET TO THE DOCTOR IN ATTENDANCE.
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:
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:
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:
RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING
APPARATUS. REMOVE ALL SOURCES OF IGNITION.
MOST IMPORTANT SYMPTOMS AND EFFECTS, BOTH ACUTE AND DELAYED:
SYMPTOMS:
SIMPLE ASPHYXIANT. MAY CAUSE SUFFOCATION BY DISPLACING THE OXYGEN IN THE
AIR. EXPOSURE TO OXYGEN-DEFICIENT ATMOSPHERE (<19.5%) MAY CAUSE DIZZINESS,
DROWSINESS, NAUSEA, VOMITING, EXCESS SALIVATION, DIMINISHED MENTAL
ALERTNESS, LOSS OF CONSCIOUSNESS AND DEATH. EXPOSURE TO ATMOSPHERES
CONTAINING 8-10% OR LESS OXYGEN WILL BRING ABOUT UNCONSCIOUSNESS WITHOUT
WARNING AND SO QUICKLY THAT THE INDIVIDUALS CANNOT HELP OR PROTECT
THEMSELVES. LACK OF SUFFICIENT OXYGEN MAY CAUSE SERIOUS INJURY OR DEATH.
MAY CAUSE CENTRAL NERVOUS SYSTEM DEPRESSION WITH NAUSEA, HEADACHE,
DIZZINESS, VOMITING, AND INCOORDINATION. CONTACT WITH EVAPORATING LIQUID
MAY CAUSE COLD BURNS/FROSTBITE.
INDICATION OF ANY IMMEDIATE MEDICAL ATTENTION AND SPECIAL TREATMENT NEEDED:
NOTE TO PHYSICIANS: TREAT SYMPTOMATICALLY.
| 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.
UNSUITABLE EXTINGUISHING MEDIA:
DO NOT USE A SOLID WATER STREAM AS IT MAY SCATTER AND SPREAD FIRE.
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: CARBON MONOXIDE. CARBON DIOXIDE (CO2).
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.
| 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. ENSURE ADEQUATE
VENTILATION, ESPECIALLY IN CONFINED AREAS. CONSIDER THE RISK OF POTENTIALLY
EXPLOSIVE ATMOSPHERES. MONITOR OXYGEN LEVEL. USE NON-SPARKING TOOLS AND
EQUIPMENT. ALL EQUIPMENT USED WHEN HANDLING THE PRODUCT MUST BE GROUNDED.
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:
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.
PROTECT CYLINDERS FROM PHYSICAL DAMAGE; DO NOT DRAG, ROLL, SLIDE OR DROP.
WHEN MOVING CYLINDERS, EVEN FOR SHORT DISTANCE, USE A CART DESIGNED TO
TRANSPORT CYLINDERS. NEVER ATTEMPT TO LIFT A CYLINDER BY ITS VALVE
PROTECTION CAP. 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 A BACKFLOW PREVENTIVE DEVICE
IN PIPING. 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.
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.
