VENTILATE CLOSED SPACES AND LOW AREAS. HYDROGEN SULFIDE IS SOLUBLE, USE
WATER SPRAY TO KNOCK DOWN VAPORS AND PROTECT PERSONNEL. DIKE RUN-OFF WATERS
FOR LATER DISPOSAL. PERSONNEL ENTERING AREA SHOULD WEAR APPROPRIATE
PROTECTIVE EQUIPMENT, INCLUDING RESPIRATORY PROTECTION SUITABLE FOR UNKNOWN
CONCENTRATIONS. PERSONNEL SHOULD NOT RE-ENTER AN AREA UNTIL HYDROGEN
SULFIDE HAS SUFFICIENTLY DISPERSED AND ADEQUATE OXYGEN RE-ESTABLISHED. IF A
LEAK IS IN USER'S EQUIPMENT, BE CERTAIN TO PURGE PIPING WITH AN INERT GAS
PRIOR TO ATTEMPTING REPAIRS. IF LEAK IS IN CONTAINER VALVE, CONTACT THE
APPROPRIATE EMERGENCY TELEPHONE NUMBER LISTED IN SECTION 1 OR CALL YOUR
CLOSEST NORCO/NORLAB LOCATION.
ENVIRONMENTAL PRECAUTIONS:
PREVENT FURTHER RELEASE (LEAKAGE/SPILLAGE) IF SAFE TO DO SO.
METHODS AND MATERIALS FOR CONTAINMENTS AND CLEANING UP:
CONTACT THE APPROPRIATE EMERGENCY TELEPHONE NUMBER LISTED IN SECTION 1 OR
CALL YOUR CLOSEST NORCO/NORLAB LOCATION. ENSURE ADEQUATE VENTILATION.

| 7 HANDLING AND STORAGE | |
HANDLING PRECAUTIONS:
USE ONLY IN WELL-VENTILATED AREAS. VALVE PROTECTION CAPS MUST REMAIN IN
PLACE ON REFILLABLE CYLINDERS UNLESS CYLINDER IS SECURED WITH VALVE OUTLET
PIPED TO USE POINT. DO NOT DRAG, SLIDE OR ROLL CYLINDERS. USE A SUITABLE
HAND TRUCK FOR CYLINDER MOVEMENT. USE A PRESSURE REDUCING REGULATOR WHEN
CONNECTING CYLINDER TO LOWER PRESSURE PIPING OR SYSTEMS. DO NOT HEAT
CYLINDER BY ANY MEANS TO INCREASE THE DISCHARGE RATE OF PRODUCT FROM THE
CYLINDER. USE A CHECK VALVE OR TRAP IN THE DISCHARGE LINE TO PREVENT
HAZARDOUS BACK FLOW INTO THE CYLINDER.
NEVER CARRY A COMPRESSED GAS CYLINDER OR A CONTAINER OF A GAS IN CRYOGENIC
LIQUID FROM IN AN ENCLOSED SPACE SUCH AS A CAR TRUNK, VAN OR STATION WAGON.
A LEAK CAN RESULT IN A FIRE, EXPLOSION, ASPHYXIATION OR A TOXIC EXPOSURE.
STORAGE REQUIREMENTS: ENSURE ADEQUATE VENTILATION.
PROTECT CYLINDERS FROM PHYSICAL DAMAGE. STORE IN A COOL, DRY, WELL
VENTILATED AREA OF NON-COMBUSTIBLE CONSTRUCTION AWAY FROM HEAVY TRAFFIC
AREAS AND EMERGENCY EXITS. DO NOT ALLOW THE TEMPERATURE WHERE CYLINDERS ARE
STORED TO EXCEED 125 DEG. F (52 DEG. C). CYLINDERS SHOULD BE STORED UPRIGHT
AND FIRMLY SECURED TO PREVENT FALLING OR BEING KNOCKED OVER. 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.
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 ANALYTICAL TESTS TO BE CERTAIN THAT THE TWA
IS NOT EXCEEDED. MANY METALS CORRODE RAPIDLY WITH WET HYDROGEN SULFIDE.
ANHYDROUS HYDROGEN SULFIDE CAN BE HANDLED IN CARBON STEEL, ALUMINUM,
INCONEL(R*), STELITE(R*), 304 AND 316 STAINLESS STEELS. AVOID HARD STEELS,
WHICH ARE HIGHLY STRESSED SINCE THEY MAY BE SUSCEPTIBLE TO HYDROGEN
EMBRITTLEMENT FROM HYDROGEN SULFIDE. MULTIPOINT AIR SAMPLERS WITH ALARMS
FOR PLANT PRODUCTION UNITS SHOULD BE PROVIDED TO CONSTANTLY MONITOR THE AIR
IN AND AROUND THE UNITS.
