^{1 NOTE: all WHMIS required information is included.  It is located in appropriate sections based on the ANSI Z400.1-1993 format.}

CONTACT WITH SKIN or EYES:  Contact with liquid or rapidly expanding gases may cause burns or frostbite.

HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. This product poses low, acute health risks.

CHRONIC: This product is not known to cause any chronic illnesses or diseases.

4. FIRST-AID MEASURES

This product is a gas; therefore, exposure via ingestion, skin contact, or eye contact would be unlikely.  Should exposure vie inhalation occur, remove victims to fresh air, as quickly as possible. Trained personnel should administer supplemental oxygen and/or cardio-pulmonary resuscitation, if necessary. Only trained personnel should administer supplemental oxygen.

In case of frostbite, place the frostbitten part in warm water. If warm water is not available, or impractical to use, wrap the affected parts gently in blankets.

If exposure causes obvious distress, victim(s) and rescuers must be taken for medical attention. Take copy of label and MSDS to physician or health professional, with victim.

5. FIRE-FIGHTING MEASURES

FLASH POINT, Degree C (method): Not applicable.
AUTOIGNITION TEMPERATURE, Degree C: Not applicable.
FLAMMABLE LIMITS (in air by volume, %):   Lower (LEL): Not applicable.
                                                                             Upper (UEL): Not applicable.

NFPA RANKING - HEALTH=2, FLAMMABILITY=0, REACTIVITY=0, OTHER=0

FIRE EXTINGUISHING MATERIALS:  None.  This product is a fire extinguishing agent.
UNUSUAL FIRE AND EXPLOSION HAZARDS:  When involved in a fire, cylinders may rupture violently, causing a high pressure release of gases. When Halon 1211 is discharged onto a fire, it decomposes and releases halogen compounds (i.e. chlorides, bromides, fluorides), which are irritating to the human respiratory system.

     Explosion Sensitivity to Mechanical Impact: Not sensitive.
     Explosion Sensitivity to Static Discharge: Not sensitive.

SPECIAL FIRE-FIGHTING PROCEDURES: Keep unused cylinders cool using a water spray. Structural fire fighters must wear Self-Contained Breathing Apparatus and full protective equipment.

6. ACCIDENTAL RELEASE MEASURES

SPILL AND LEAK RESPONSE:  Uncontrolled releases should be responded to by trained personnel using pre-planned procedures. Proper protective equipment should be used. In case of a release, clear the affected area, protect people, and respond with trained personnel. For uncontrolled releases, respond wearing Self-Contained Breathing Apparatus. Monitor the surrounding area for oxygen content. The atmosphere must have at least 19.5 percent oxygen before personnel can be allowed in the area without Self-Contained Breathing Apparatus. Ventilate the affected area.

7. HANDLING and STORAGE

WORK PRACTICES AND HYGIENE PRACTICES: Avoid getting chemicals ON YOU or IN YOU.  Wash hands after handling chemicals. Do not eat, drink, or smoke while handling chemicals. Be aware of any signs of dizziness or fatigue; exposures to fatal concentrations of this product could occur without any significant warning symptoms.
STORAGE AND HANDLING PRACTICES: All employees who handle this material should be trained to handle it safely. Keep cylinders in dry, well-ventilated areas which are away from sources of heat. Keep cylinders secure.
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Follow practices indicated in Section 6 (Accidental Release Measures). Make certain application equipment is locked and tagged-out safely. Always use this product in areas where adequate ventilation is provided. Decontaminate equipment using soapy water before maintenance begins. Collect all rinsates and dispose of according to applicable Federal, State, or local procedures.

8. EXPOSURE CONTROLS - PERSONAL PROTECTION

VENTILATION AND ENGINEERING CONTROLS: Use with adequate ventilation. Use a mechanical fan or vent area to outside.
RESPIRATORY PROTECTION:  Use supplied air respiratory protection if oxygen levels are 19.5%.
EYE PROTECTION: Safety glasses.
HAND PROTECTION: None normally required.
BODY PROTECTION: Use body protection appropriate for task.

9. PHYSICAL and CHEMICAL PROPERTIES

10. STABILITY and REACTIVITY

STABILITY: Stable.
DECOMPOSITION PRODUCTS: When Halon 1211 is discharged into a fire, it decomposes above 900 degrees F, releasing bromide ions (the extinguishing agent). Halogen compounds, such as halogen acids, are also formed.  These by-products although harmful if inhaled, are easily detected. Only a few PPM creates an unpleasant, acrid odor which serves as a warning to the user. After the extinguisher is discharged, the area should be vacated until ventilation clears the area.
MATERIALS WITH WHICH SUBSTANCE IS INCOMPATIBLE: Active metals, such as powdered alumina and magnesium.
HAZARDOUS POLYMERIZATION: Will not occur.
CONDITIONS TO AVOID: Incompatible materials.

16. OTHER INFORMATION

DEFINITIONS OF TERMS

A large number of abbreviations and acronyms appear on an MSDS. Some of these which are commonly used include the following:

Fire extinguishers are designed and produced for the specific purpose of providing a safe and efficient safety tool to be used only in the fighting of fires. Improper or careless use may cause severe bodily injury and/or property damage.

Contents are under pressure which is necessary to deliver the contained extinguishing agent to the fire source. Please take note of the following safety information:

• Contents are under pressure. Do not puncture, incinerate, or discharge into another person's face.
  
  
• Do not store at high temperatures above 120 degrees F or 49 degrees C.
  
  
• Keep away from small children.
  
  
• Do not use if the extinguisher appears to be damaged or corroded.
  
  
• Avoid inhaling the extinguishing agent. Avoid inhaling smoke and fumes - all fires release toxic substances that are harmful. DO NOT remain in a closed area after use; evacuate the area immediately and ventilate thoroughly before re-entering.
  
  
• Although extinguishing agents are non-toxic when used properly, contact with them may cause irritation to eyes, nose, throat, and other allergic symptoms.

Refer to specific extinguishing agent material safety data sheet for additional information.
