Section IV - Fire and Explosion Hazard Data



FLASH POINT (Method used): 12 C (54 F) CC              AUTO IGNITION TEMPERATURE: 463 C (867 F)                FLAMMABLE LIMITS           LEL 6%           UEL 36%



EXTINGUISHING MEDIA: Use extinguisher media appropriate for surrounding fire since sample is small. Alcohol foam, dry chemical or carbon dioxide (water may be

ineffective in most laboratory situations).



SPECIAL FIRE FIGHTING PROCEDURES: Firefighters should wear proper protective equipment and self contained breathing apparatus with full face piece operated in

positive pressure mode. Move containers from fire area if it can be done without risk. Use water to keep fire-exposed containers cool.



UNUSUAL FIRE AND EXPLOSION HAZARDS: Vapors may flow along surfaces to distant ignition sources and flash back. Closed containers exposed to heat may

explode. Contact with strong oxidizers may cause fire. Burns with a clear, almost invisible flame.







Section V - Reactivity Data

INCOMPATIBILITY (Materials to avoid):

Strong oxidizing agents, strong acids, zinc, aluminum, magnesium.



HAZARDOUS DECOMPOSITION PRODUCTS: Carbon monoxide, carbon dioxide, formaldehyde.



        HAZARDOUS                  May Occur              Will Not Occur         Conditions to Avoid: None Known

nausea, vomiting, dizziness, gastrointestinal irritation, central nervous system depression, hearing loss.



COMPONENTS LISTED AS CARCINOGENS OR POTENTIAL CARCINOGENS: None listed in IARC Monograph.

SIGNS AND SYMPTOMS OF EXPOSURE: Irritation of skin, eyes, nose, throat and headache. Prolonged contact may cause dermatitis. Exposure effects may differ

                                                                                                                                                               Page 2

between individuals.



MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: Eye disorders, skin disorders, liver or kidneys disorders.



EMERGENCY AND FIRST AID PROCEDURES: Seek medical assistance for treatment, observation and support if necessary. EYE CONTACT: Flush with water,

obtain medical attention. SKIN CONTACT: Wash with soap and water, use protective creams INHALATION: Remove to fresh air, if not breathing, give artificial

respiration. If breathing is difficult, give oxygen, obtain medical attention. INGESTION: If conscious, give water and baking soda, induce vomiting. Obtain medical

assistance immediately.







Section VII - Precautions for Safe Handling and Use



STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: (Sample) shut off ignition sources. No flares, smoking or flames in area. Take up with sand

or other non-combustible absorbent material and place into container for later disposal. Flush area with water.



WASTE DISPOSAL METHOD: Dispose in accordance with all applicable federal, state, and local environmental regulations. Excess sample should be placed in a

proper waste solvent container.



PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE: Keep container tightly closed, store in a cool, dry, well ventilated, flammable liquid storage area.



OTHER PRECAUTIONS* Do not heat or evaporate sample to dryness.







Section VIII - Control Measures



RESPIRATORY PROTECTION (Please specify): (Methanol) MSHA/NIOSH approved respirator with organic vapor cartridge, required if airborne concentration exceeds

TWA of 200 ppm.



VENTILATION: Local exhaust. General or local exhaust to meet TLV regulations.



PROTECTIVE GLOVES: Rubber gloves recommended.                                        EYE PROTECTION: Safety glasses or goggles.



OTHER PROTECTIVE EQUIPMENT: Impervious clothing



EMERGENCY WASH FACILITIES: Maintain eye wash and quick drench showers in work area.
