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. Concentrations of carbon monoxide less than or equal to 20% in nitrogen are considered non-
flammable (CGA P-23, 1995).
Cylinders may rupture violently from pressure when involved in a fire situation.
See Section 7 for more information on safe handling.
See Section 8 for more information on personal protection equipment.
See Section 13 for disposal information.
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/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 8 for information on personal protection equipment.
See Section 13 for information on proper disposal.
7 HANDLING AND STORAGE
Handling Precautions:
Carbon monoxide can be handled in all commonly used metals up to approximately 500 psig
(3450 kPa). Above that pressure it forms toxic and corrosive carbonyl compounds with some
metals. Carbon steels, aluminum alloys, copper and copper alloys, low carbon stainless
steels and nickel-based alloys such as Hastelloy A, B & C are recommended for higher
pressure applications.
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
