Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Irritating to eyes.The toxicological properties of this material have not been fully investigated.
Potential Health Effects
Eye:
Causes severe eye irritation. May result in corneal injury.
Causes redness and pain.
Skin:
Causes skin irritation.
Ingestion:
May cause irritation of the digestive tract.
Inhalation:
May cause respiratory tract irritation. Inhalation of appreciable amounts of vapor under normal conditions is unlikely because of the materials low vapor pressure. Hazardous concentrations may develop at elevated temperatures.
Chronic:
No information found.
Section 4 - FIRST AID MEASURES
Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.
Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Clean up spills immediately, observing precautions in the Protective Equipment section. Provide ventilation.
Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.
Storage:
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use only under a chemical fume hood.
Exposure Limits CAS# 502-44-3: Personal Protective Equipment Eyes: Wear chemical splash goggles.
Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
A respiratory protection program that meets OSHAs 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant respirator use.

Section 11 - TOXICOLOGICAL INFORMATION
RTECS#:
CAS# 502-44-3: MO8400000 LD50/LC50:
CAS# 502-44-3: Oral, rat: LD50 = 4290 mg/kg; Skin, rabbit: LD50 = 5990 uL/kg.
Carcinogenicity:
epsilon-Caprolactone monomer - Not listed by ACGIH, IARC, or NTP.
Other:
See actual entry in RTECS for complete information.
Section 12 - ECOLOGICAL INFORMATION
Ecotoxicity:
Estimated Koc value = 109.1. This value suggests that episolon-Caprolactone will show high mobility in soil. Estimated BCF value = 4.94. This values indicates that bioconcentration of this product in aquatic organisms and sediment should not be important.
Epsilon-Caprolactone exists in the vapor phase in the ambient atmosphere and will be degraded slowly by the reaction with photochemically produced hydroxyl radicals.
