SECTION 3 HAZARDS IDENTIFICATION
Emergency Overview: Flammable liquid. Hazardous polymerization may occur. May cause eye,
respiratory tract and skin irritation. Prolonged or repeated contact may cause allergic skin reaction (skin
sensitization).
EU Preparation Classification (1999/45/EC): F, Xi, R11, R36/37/38, R43, R52/53.
SECTION 4 FIRST AID MEASURES
Eye Contact: Flush eyes with water for at least 15 minutes, holding the eyelids apart. Get medical
attention if irritation persists.
Skin Contact: Wash skin with soap and water. Get medical attention if irritation develops. Launder
contaminated clothing before re-use.
Ingestion: If small quantities are swallowed, rinse out mouth with water. Do not induce vomiting. Never give
anything by mouth to an unconscious or drowsy person. Get immediate medical attention.
Inhalation: Remove victim to fresh air. Get medical attention if irritation persists.

SECTION 5 FIRE FIGHTING PROCEDURES
Extinguishing Media: Use carbon dioxide, foam or dry chemical.
Firefighting Procedures: Do not enter fire area without proper protection. Fight fire from safe distance or
protected location. Firefighters should wear full emergency equipment and NIOSH approved positive
pressure self-contained breathing apparatus.
Unusual Fire/Explosion Hazards: Fine mists are explosive below the flash point. Vapors are heavier than
air and may travel to ignition source and flash back. Heat of fire may cause an exothermic
autopolymerization reaction. Emits toxic fumes under fire conditions. Closed containers may explode due
to pressure build up when exposed to extreme heat.
Known or Anticipated Hazardous Products of Combustion: Carbon monoxide, carbon dioxide, nitrogen
oxides, ammonia, and methyl methacrylate.
SECTION 6 ACCIDENTAL RELEASE MEASURES
Accidental Release Measures: Provide explosion-proof ventilation. Wear appropriate protective clothing
as described in Section 8. Eliminate all ignition sources. Contain and absorb spills with inert material and
transfer to a suitable container for disposal. Do not allow spills to be released into the environment.
Personal Precautions: Avoid contact with skin, eyes or clothing. Avoid breathing vapors.
Environmental Precautions: This material is harmful to aquatic organisms. Do not allow spills to enter
sewers or waterways.
SECTION 7 HANDLING AND STORAGE
Handling: Avoid contact with eyes, skin, and clothing. Avoid breathing vapors or mist. Wash thoroughly
after handling. Wear protective clothing and equipment as described in Section 8. Use with adequate
ventilation. Keep away from heat, sparks and flames. Ground container when pouring. Do not expose to
direct sunlight.
Empty containers retain product residues can be hazardous. Follow all MSDS precautions when handling
empty containers.
Storage: If inhibitors are depleted, product can polymerize, raising temperature and pressure, possibly
rupturing container. Store in a cool, dry, well ventilated area. Keep container tightly closed when not in
use. Do not store in direct sunlight. Prevent moisture contact. Protect from physical damage. Keep away
from oxidizers and other incompatible materials.
SECTION 8 EXPOSURE CONTROLE/PERSONAL PROTECTION
Occupational Exposure Limits:

None Established
1,6-Hexanediol Dimethacrylate
Engineering Controls: Use ventilation that is adequate to keep employee exposure to airborne
concentrations below exposure limits. Use explosion-proof equipment where required.
Personal Protective Equipment:
Eye Protection: Wear safety glasses. Wear coverall chemical splash goggles and face shield when
possibility exists for eye and face contact due to splashing or spraying material.
Skin Protection: Wear nitrile rubber or other impervious gloves to minimize skin contact.

Respiratory Protection: A NIOSH/MSHA approved air-purifying respirator with an organic vapor cartridge
or canister may be permissible under certain limited circumstances where airborne concentrations are
expected to exceed exposure limits. Protection provided by air purifying respirators is limited. Use a
positive pressure air supplied respirator if there is any potential for an uncontrolled release, exposure
levels are not known, or any other circumstances where air purifying respirators may not provide adequate
protection. Selection and use of respiratory equipment must be in accordance with OSHA 1910.134 and
good industrial hygiene practice.
Other Protective Clothing or Equipment: Wear impervious clothing to prevent any contact with this
product, such as gloves, apron, boots, or whole body suit. Nitrile rubber is better than PVC.

SECTION 10 STABILITY AND REACTIVITY
Stability: Unstable if heated.
Conditions to Avoid (stability): Heat, sparks, open flame and other ignition sources, elevated
temperatures, inhibitor depletion, exposure to radiation, direct sunlight, freezing conditions.
Incompatibility with Other Materials: Avoid contact with oxidizing agents, reducing agents, free radical
initiators, inert gases, oxygen scavengers, tertiary amines, heavy metals, peroxides, polymerization
initiators.
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, nitrogen oxides, ammonia, and
methyl methacrylate.
Hazardous Polymerization: Polymerization can occur. Conditions leading to polymerization are excessive
heat, storage in absence of inhibitor, and inadvertent addition of catalyst. Contamination of product may
also cause hazardous polymerization.
SECTION 11 TOXICOLOGICAL INFORMATION
Potential Health Effects:
Eyes: Liquid and vapors can cause moderate irritation (tears, blurred vision and redness).
Skin: May cause skin irritation with allergic skin reaction (skin sensitization). May be absorbed through the
skin causes symptoms similar to inhalation.
Inhalation: May cause respiratory tract irritation with coughing, mucous production and shortness of
breath. High concentration is irritating to the respiratory tract and may cause dizziness, headache and
anesthetic effects.
Ingestion: Causes irritation, a burning sensation of the mouth, throat and gastrointestinal tract and
abdominal pain.
