Target Organs: Eye, the skin, respiratory system

Potential Health Effects

Eye: Causes eye irritation

Skin: Causes skin irritation. May cause allergic skin reaction.

Ingestion: May cause gastrointestinal irritation with nausea, vomiting 
and diarrhea.

Inhalation: Causes respiratory tract irritation.

Chronic: Repeated contact may cause skin sensitization.

Section 4: First Aid Measures



Eyes: In case of eye contact, flush eyes with copious amounts of 
water for at least 15 minutes.  Seek medical attention.

Skin: Flush skin with copious amounts of water for at least 15 
minutes.  If irritation occurs, seek medical attention.

Ingestion: Do not induce vomiting. If conscious and alert, rinse 
mouth and drink2 to 4 cupfuls of milk or water.  Never give anything by 
mouth to an unconscious person.  Seek medical attention. 

Inhalation: Remove to fresh air.  If not breathing, give artificial 
respiration.  If breathing is difficult, give oxygen.  Seek medical attention.

Section 5: Fire Fighting Measures

      

General Information:
	Flash point: 64°F
	Explosion Limits
		Upper: Not available
		Lower: 1.8
	Flammability Classification: IB

Wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH 
approved or equivalent, full firefighter protective gear. Vapors may 
form an explosive mixture with air.  Use water spray to keep fire-exposed 
containers cool. Fire or excessive heat may cause violent rupture of the 
container due to bulk polymerization. Closed containers may rupture 
violently when heated. Vapors are heavier than air and may travel to a 
source of ignition and flash back.  Vapors may collect in low or confined 
areas.


Extinguishing Media:
Dry chemical, carbon dioxide, water spray, or alcohol-resistant foam. Do 
not use straight streams of water.

Section 6: Accidental Release Measures

      

General Information:
Remove all ignition sources.

Spills/Leaks:
Absorb with inert material such as vermiculite or sand, and place in 
suitable container for disposal.  Use non-sparking tool.  Avoid runoff 
into storm sewers or ditches which lead to waterways.

Section 7: Handling and Storage


Handling:
Avoid contact with eyes and skin. Avoid ingestion and inhalation. Use 
with adequate ventilation. Wash clothing before reuse.



Storage:
Store at 4°C in tightly closed containers in flammables area.

Section 8: Exposure Controls and Personal Protection


Engineering Controls:
Use local exhaust ventilation or process enclosures. Eyewash station and 
safety shower must be available to the work area.

Personal Protective Equipment

Eyes: Chemical splash goggles and face shield

Skin: Latex or equivalent gloves

Clothing: Suitable clothing to avoid skin contact

Respirators: Where exposure limits may be exceeded, use NIOSH/MHA or 
European Standard EN 149 approved full-face airline respirator in positive 
pressure mode.
