| 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. |
