03. HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW:

Danger:
High Pressure Gas

Do not breath gas

Can cause rapid suffocation

Self contained breathing apparatus may be required by rescue workers

Potential Health Effects Information:

Inhalation:
Simple asphyxiate. Helium is nontoxic, but may cause suffocation by displacing the

oxygen in air. Exposure to oxygen-deficient atmosphere (<19.5%) may cause

dizziness, drowsiness, nausea, vomiting, excess salivation, diminished mental

alertness, loss of consciousness and death. Exposure to atmospheres containing

8-10% or less oxygen will bring about unconsciousness without warning and so

quickly that the individuals cannot help or protect themselves. Lack of sufficient

oxygen may cause serious injury or death.

Warning:
The practice of intentionally inhaling helium for a voice altering effect is extremely

dangerous and may result in serious injury or death.

Eye:
None.

Skin:
None.

Ingestion:
None.

Chronic Effects:
None established.

Medical Conditions Aggravated By
None.

Overexposure:

Carcinogenicity:
Not listed in NTP, OSHA or IARC
04. FIRST AID MEASURES

Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is

difficult, give oxygen. Get immediate medical attention.

Eye:
None.

Skin:
None.

Ingestion:
None.

Notes To Physician:
None.
05. FIRE FIGHTING MEASURES

Flash Point:
Not applicable; Gas.

Autoignition:
None

Flammable Limits - Lower:
Not applicable.

Flammable Limits - Upper:
Not applicable

Extinguishing Media:
Nonflammable, does not support combustion. Use extinguishing media appropriate

for the surrounding fire.

Fire Fighting Instructions:
Simple asphyxiant. If possible, without risk, remove cylinders from fire area or cool

with water. Self-contained breathing apparatus may be required for rescue

workers.

Containers can build up pressure if exposed to heat (fire).

Fire And Explosion Hazards:
Upon exposure to intense heat or flame cylinder may vent rapidly and/or rupture

violently. Most cylinders are designed to vent contents when exposed to elevated

temperatures. Pressure in a container can build up due to heat and it may rupture if

pressure relief devices should fail to function.

Hazardous Combustion Products:
None known.

Sensitivity To Static Discharge:
None.

Sensitivity To Mechanical Impact:
None.
06. ACCIDENTAL RELEASE MEASURES

Evacuate:
Evacuate all personnel from the affected area. Shut off source of helium, if without

risk. Ventilate enclosed areas or remove cylinders to an outdoor location. If

leaking from cylinder or its valve, contact your supplier.
07. HANDLING AND STORAGE

Storage:
Store and use with adequate ventilation. Cylinders should be stored upright with

valve protection cap in place and firmly secured to prevent falling or being knocked

over. Protect cylinders from physical damage; do not drag, roll, slide or drop. Do

not allow storage area temperature to exceed 125°F (52°C). Full and empty

cylinders should be segregated. Use a first-in, first-out inventory system to prevent

full containers from being stored for long periods of time.

Handling:
Use a suitable hand truck for cylinder movement. Never attempt to lift a cylinder by

its valve protection cap. If user experiences any difficulty operating cylinder valve

discontinue use and contact supplier. Never insert and object (e.g., wrench,

screwdriver, pry bar, etc.) into valve cap openings. Doing so may damage valve,

causing leak to occur. Use an adjustable strap wrench to remove over tight or

rusted caps. Never strike an arc on a compressed gas cylinder or make a cylinder a

part of an electrical circuit. For additional precautions in using helium see Section

16 - Other Information
08. EXPOSURE CONTROLS - PERSONAL PROTECTION

Engineering Controls:

Ventilation:
Natural or mechanical to prevent oxygen-deficient atmospheres under 19.5%

oxygen.

Personal Protective Equipment (PPE):

Skin Protection:
None required.

Glasses:
Safety glasses are recommended when handling cylinders.

Shoes:
Safety shoes are recommended when handling cylinders.

Gloves:
Work gloves are recommended when handling cylinders.

Respirator:
Self contained breathing apparatus (SCBA) or positive pressure airline with mask

are to be used in oxygen-deficient atmosphere. Air purifying respirators will not

provide protection.
