3. Hazards Identification
EMERGENCY OVERVIEW
CAUTION! High-pressure gas.
Can cause rapid suffocation.
May cause dizziness and drowsiness.
Self-contained breathing apparatus may be required by rescue workers.
Odor: None
THRESHOLD LIMIT VALUE: Simple asphyxiant (ACGIH, 2002). ACGIH recommends a TLV-
TWA of 5 mg/m3 for welding fumes not otherwise classified (NOC) that may be generated during
welding with this product. See section 16 for more information on welding hazards. TLV-TWAs should
be used as a guide in the control of health hazards and not as fine lines between safe and dangerous
concentrations.

Product: Helium
P-4602-F
Date: January 2003
OSHA: OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION:
29 CFR 1910.119: PROCESS SAFETY MANAGEMENT OF HIGHLY HAZARDOUS
CHEMICALS: Requires facilities to develop a process safety management program based on
Threshold Quantities (TQ) of highly hazardous chemicals.
Helium is not listed in Appendix A as a highly hazardous chemical.
STATE REGULATIONS:
CALIFORNIA: Helium is not listed by California under the SAFE DRINKING WATER AND
TOXIC ENFORCEMENT ACT OF 1986 (Proposition 65).
PENNSYLVANIA: This product is subject to the PENNSYLVANIA WORKER AND
COMMUNITY RIGHT-TO-KNOW ACT (35 P.S. Sections 7301-7320).
16. Other Information
Be sure to read and understand all labels and instructions supplied with all containers of this product.
OTHER HAZARDOUS CONDITIONS OF HANDLING, STORAGE, AND USE: High-pressure
gas. Use piping and equipment adequately designed to withstand pressures to be encountered. Gas can
cause rapid suffocation due to oxygen deficiency. Store and use with adequate ventilation at all times.
Close valve after each use; keep closed even when empty. Never work on a pressurized system. If there is
a leak, close the cylinder valve. Blow the system down in a safe and environmentally sound manner in
compliance with all federal, state, and local laws; then repair the leak. Never place a compressed gas
cylinder where it may become part of an electrical circuit.
SPECIAL PRECAUTIONS: Use in welding and cutting. Read and understand the manufacturer’s
instructions and the precautionary label on the product. See American Standard Z49.1, Safety in Welding,
Cutting, and Allied Processes, published by the American Welding Society, www.aws.org—order from
Global Engineering Documents, 15 Inverness Way East, Englewood, CO 80112-5776 and OSHA
Publication 2206 (29CFR 1910), US Government Printing Office, Washington, DC 20402, for more
information.
Arcs and sparks can ignite combustible materials. Prevent fires. Refer to NFPA 51B, Standard for Fire
Prevention in Welding, Cutting, and Other Hotwork. Do not strike an arc on the cylinder. The defect
produced by an arc burn could lead to cylinder rupture.
Use in Underwater Breathing. Suitability of this product for use in underwater breathing must be
determined by or under supervision of someone experienced in the use of underwater breathing gas
mixtures. This person must be familiar with how the product is used; the frequency, duration, and effects
of use; the hazards and side effects of use, and the precautions to take to avoid or control them.
MIXTURES: When you mix two or more gases or liquefied gases, you can create additional,
unexpected hazards. Obtain and evaluate the safety information for each component before you produce
the mixture. Consult an industrial hygienist or other trained person when you evaluate the end product.
Remember, gases and liquids have properties that can cause serious injury or death.
