Hazards Identification
  For Humans:  
  EU Classification: Nonflammable gas
  R Phrases: None
  S Phrases: Keep container in a well ventilated place.
  Limit Values for Exposure:
  OSHA PEL: None established
  ACGIH TLV-TWA: None established
  ACGIH TLV-STEL: None established
  IDLH: None established
  Neither this preparation nor the substances contained in it have been listed as carcinogenic by National Toxicology Program, I.A.R.C., or OSHA
  Signs & Symptoms:  
  Acute Exposure:  
  Eye Contact: Non-irritating gas.
  Skin Contact: Non-irritating gas.
  Inhalation: Can cause suffocation by reducing oxygen available for breathing.
Breathing very high concentrations of vapour can cause dizziness, shortness of breath, unconsciousness or even death.
  Ingestion: Non-irritating gas. Not a probable route of exposure.
  Chronic Overexposure: No data available.
  Medical conditions generally aggravated by exposure:  None known.
  For Environment: This is a component of the atmosphere.

4.

First Aid Measures
  Eye Contact: Avoid direct contact of high pressure gas discharge.
  Skin Contact: Avoid direct contact of high pressure gas discharge.
  Inhalation: Avoid direct inhalation of undiluted gas. Gas is an asphyxiant.
  Ingestion: Not a probable route of exposure.

5.

Firefighting Measures
  Non-flammable gas. Use agent appropriate to surrounding material.
Though gas cylinders are equipped with pressure and temperature relief devices, they should be removed from high temperature areas or fires, if safe to do so, to avoid risk of rupture.
There are NO extinguishing media which must not be used for safety reasons.
NO special protective equipment is needed for firefighters.

6.

Accidental Release Measures
  Material is a normal atmospheric gas.
NO harm to the environment is expected from an accidental release of this preparation.

7.

Handling and Storage
7.1 Handling
  Care should be taken in handling all chemical substances and preparations.
Secure to prevent falling. Do not move without safety cap in place to prevent damage to valve.
See incompatibility information in Heading 10.
7.2 Storage
  Store cylinders with restraints to prevent possibility of rupture. Store as a compressed gas in DOT approved vessels. Keep safety cap in place while in storage.
See incompatibility information in Heading 10.
Store in original container. Keep tightly closed until used.
There is NO danger to the environment from a storage release.
7.3 Specific use
  The intended or recommended use of this preparation is as a fire extinguishing agent.

8.

Exposure Controls/Personal Protection
8.1 Exposure limit values
  There are NO currently occupational exposure limit values for this component.
8.2 Exposure controls
  8.2.1 Occupational exposure controls
    8.2.1.1. Respiratory protection

    8.2.1.2 Hand protection
      Use leather gloves when handling cylinders.
    8.2.1.3 Eye protection
      Use safety glasses with side shields or safety goggles.
    8.2.1.4 Skin protection
      No special equipment is needed.
  8.2.2 Environmental exposure controls
    None needed. This material is a normal atmospheric gas.
