Special Hazards Arising From the Substance or Mixture:
Hydrogen gas
Nitrogen gas
Nitrogen Oxides (NOx)
Oxygen gas
Advice for Firefighters:
If possible, stop the flow of gas supply. Continue to cool heat or flame exposed containers until well after the flames are
extinguished. Firefighters should wear a full-face piece, NIOSH/MSHA-approved self-contained breathing apparatus
(SCBA) operated in positive pressure mode and full turnout gear.
Further Information:
If incinerated, may release toxic fumes.
Use water spray to cool unopened containers.
Product is non-flammable. Concentration of hydrogen is below the
sufficient oxygen to support combustion.
Cylinders may rupture violently from pressure when involved in a fire situation.

6 ACCIDENTAL RELEASE MEASURES
Personal Precautions, Protective Equipment and Emergency Procedures:
Evacuate all personnel from affected area. Use appropriate protective equipment. If leak is in user's equipment, be certain to
purge piping with inert gas prior to attempting repairs. If leak is in container or valve, contact the appropriate emergency
telephone number listed in Section 1 or call your closest Norco/NorIab 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/NorIab 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:
Storage Requirements:
Use only in well-ventilated areas. Valve protection caps must remain in place unless
container 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 (<3000 psig) piping 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 backflow 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.
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. Post "NO SMOKING OR OPEN
FLAMES" sign in the storage or use area.
For additional recommendations, consult Compressed Gas Association Pamphlet P-1.

Component(s): Air; Hydrogen
EXPOSURE
CONTROlS/PERSONAl
All ventilation should be designed in accordance with OSHA standard (29 CFR 1910.94). Use
local exhaust at filling zones and where leakage and dust formation is probable. Use
mechanical (general) ventilation for storage areas. Use appropriate ventilation as required to
keep Exposure Limits in Air below
Eye/face protection:
When using material use safety goggles and gloves as appropriate for the job. All safety
equipment should be tested and approved under appropriate government standards such as
NIOSH (US) or EN 166 (EU).
Skin protection:
Not required, but may be used. Gloves must be inspected prior to use. Dispose of
contaminated gloves according to applicable laws and workplace practices.
Body Protection:
Not required, but may be used. Type of protective equipment should be selected based on
concentration amount and conditions of use of this material. Use safety shoes.
Respiratory protection:
Not required. A positive pressure air line with full-face mask and escape bottle or
self-contained breathing apparatus should be available for emergency use.
Control of environmental exposure:
Prevent leakage or spillage if safe to do so.
