Remove contaminated clothing and shoes without delay. Wash immediately with plenty of water. Do not reuse contaminated clothing without laundering. Get medical attention if pain or irritation persists after washing or if signs and symptoms of overexposure appear.
Ingestion:
If swallowed, call a physician immediately. Only induce vomiting at the instruction of a physician. Never give anything by mouth to an unconscious person.
Inhalation:
Remove to fresh air. If breathing is difficult, give oxygen. Obtain medical advice if there are persistent symptoms.

high pressure water jet.
Protective Equipment:
Firefighters, and others exposed, wear self-contained breathing apparatus. Wear full firefighting protective clothing. See MSDS Section 8 (Exposure Controls/Personal Protection).
Special Hazards:
Keep containers cool by spraying with water if exposed to fire.

Personal precautions:
Where exposure level is not known, wear approved, positive pressure, self-contained respirator. Where exposure level is known, wear approved respirator suitable for level of exposure. In addition to t
he protective clothing/equipment in Section 8 (Exposure Controls/Personal Protection), wear impermeable boots.
Methods For Cleaning Up:
Remove sources of ignition. Cover spills with some inert absorbent material; sweep up and place in a waste disposal container. Flush spill area with water.
Environmental Precautions:
None known

7. HANDLING AND STORAGE
HANDLING
reactive materials studiesPrecautionary Measures: Avoid contact with eyes, skin and clothing. Avoid breathing vapor or mist. Keep container tightly closed. Use with adequate ventilation. Wash thoroughly after handling.
Special Handling Statements: Product exposed to sunlight will slowly polymerize.
STORAGE
Containers which are opened must be carefully resealed and kept upright to prevent leakage.  Prevent unauthorised access.  Storage in stainless steel, amber glass, amber polyethylene or baked phenolic lined container.  Keep containers tightly closed. Keep away from heat.
Storage Temperature:  Store at  4 -  40 °C  39.2 -  104 °F
Reason: Safety.
_____________________________________________________________________________ 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Measures:
Utilize a closed system process where feasible. Where this material is not used in a closed system, good enclosure and local exhaust ventilation should be provided to control exposure.
Respiratory Protection:
For operations where inhalation exposure can occur use an approved respirator. Recommendations are listed below. Other protective respiratory equipment may be used based on user's own risk assessment.
Recommended respirators include those certified by NIOSH.
Recommended:Full Face Mask with organic vapor cartridge, Type A filter (BP >65°C)
Eye Protection:
Prevent eye and skin contact. Provide eye wash fountain and safety shower in close proximity to points of potential exposure. Wear eye/face protection such as chemical splash proof goggles or face shield.
Skin Protection:
Prevent contamination of skin or clothing when removing protective equipment. Wear impermeable gloves and suitable protective clothing.
Hand Protection:
Wear protective gloves. Recommendations are listed below. Other protective materials may be used based on user's own risk assessment. Barrier creams may help to protect the exposed areas of the skin, they should however not be applied once exposure has occurred. Replace gloves immediately when torn or any change in appearance (dimension, color, flexibility etc.) is noticed.
Gloves for short term exposure:Laminated multilayer gloves, break through time:  > 60 min
Nitrile rubber (NBR), thickness:  > 0.56 mm, break through time:  < 60 min
The chemical resistance depends on the type of product and amount of product on the glove. Therefore gloves need to be changed when in contact with chemicals.
Not suitable gloves:Latex gloves
Due to many conditions (e.g. temperature, abrasion) the practical usage of a chemical protective glove in practice may be much shorter than the permeation time determined through testing.
Additional Advice:
Food, beverages, and tobacco products should not be carried, stored, or consumed where this materia
l is in use. Before eating, drinking, or smoking, wash face and hands thoroughly with soap and water.

_____________________________________________________________________________ 10. STABILITY AND REACTIVITY
Stability:Stable
Conditions To Avoid:Avoid exposure to strong UV sources. Avoid friction with temperature increase as
result. Avoid direct contact with heat sources. Avoid temperatures higher than 60°C.
Protect from direct sunlight.

Conditions To Avoid:Hazardous polymerization can occur when exposed to direct sunlight. Hazardous
exothermic polymerization can occur when heated. Uncontrolled polymerization may
cause rapid evolution of heat and increase in pressure that could result in violent
rupture of sealed storage vessels or containers
Materials To Avoid:Avoid contact with oxidizing agents.
Avoid contact with acids and alkali''s.
Avoid free radical producing initiators.
Avoid contact with reactive metals.
Avoid contact with peroxides.
Unintentional contact with them should be avoided.

11. TOXICOLOGICAL INFORMATION
Toxicological information for the product is found under Section 2.  HAZARDS IDENTIFICATION.
Toxicological information on the regulated components of this product is as follows:
Trimethylolpropane triacrylate has acute oral (rat) LD50 and acute dermal (rabbit) LD50 values of 5760 mg/kg and 7050 mg/kg, respectively.  Direct contact with this material may cause moderate eye and skin irritation.  Repeated or prolonged skin contact may cause allergic skin reactions.  Results of in vitro mutagenicity testing for trimethylolpropane triacrylate are mixed with both positive and negative findings. Trimethylolpropane triacrylate may cause mutagenic eefects based on in vitro studies.  However, a more definitive in vivo study indicates trimethylolpropane triacrylate is not mutagenic (non-genotoxic).  Additionally, in a long-term bioassay in which  trimethylolpropane triacrylate was applied dermally to mice, trimethylolpropane triacrylate was determined to be non-carcinogenic.  Therefore, the weight of the evidence of various genotoxicity (mutagenicity) test results leads to the conclusion that trimethylolpropane triacrylate is not mutagenic.
In January 2013, the National Toxicology Program (NTP) released their final report regarding the toxicology and carcinogenesis studies of Trimethylolpropane triacrylate (TMPTA). The report indicates that there was some evidence of carcinogenic activity of TMPTA in a 2-year dermal study that was conducted in rodents.  At least one or more of the findings are notably specific to rodents and should have no relevance to humans.  The other findings are believed by some experts to be inappropriately related to the treatment with TMPTA.  Further investigation of the findings in this study is ongoing.
California Proposition 65 Warning (applicable in California only) - This product contains (a) chemical(s) known to the State of California to cause birth defects or other reproductive harm.
