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: Do not 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.
