CASES OF OVEREXPOSURE. RESCUE PERSONNEL
Immediately remove to fresh air. If breathing is difficult, administer oxygen. If breathing has stopped, give
artificial respiration. Keep victim warm and calm. Further treatment should be symptomatic and
supportive. Seek immediate medical attention.
Note to physician: Acute hydrogen sulfide poisoning can be treated by induction of methemoglobinemia
through parenteral injection of methemoglobin generating agents (i.e. sodium nitrile). This acts as an
antidote by restoring the normal activity of the sulfide inhibited enzyme.
Remove contaminated clothing and flush affected area with large quantities of water. If irritation persists or

See Section 13 for disposal information.
6 ACCIDENTAL RELEASE MEASURES
Personal Precautions, Protective Equipment and Emergency Procedures:
Isolate hazard area, evacuate personnel and deny entry to unauthorized/unprotected individuals. Extinguish all ignition
sources and 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.
Reference to Other Sections:
See Section 7 for information on safe handling.
See Section 8 for information on personal protection equipment.
See Section 13 for information on proper disposal.
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.
Storage Requirements:
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.
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 °F (52 °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 ®, Stelite ®, 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.
For additional recommendations, consult Compressed Gas Association Pamphlet P-1.
