might be at increased risk from ethyl acetate exposure. Persons undergoing ANTABUSE treatment might experience violent gastrointestinal distress, flushing or hypotension. Tobacco smoking increases risk of lung disease in workers exposed to ethyl acetate. Persons simultaneously exposed to ethanol or acetaldehyde might be more sensitive.

See toxicological information (section 11)
FIRST AID MEASURES
: Check for and remove any contact lenses. Immediately flush the eyes with running water for at least 15 minutes, keep eyelids open. Cold water may be used. DO NOT use eye ointment. Get medical attention. Skin contact
: In the case of contact, flush the skin with plenty of water. Gently and thoroughly wash the contaminated skin with running water and non- abrasive soap. Be particularly careful to clean folds. Cervices, creases and groin. Cover the irritated skin with an emollient. Wash clothes before reuse. Thoroughly clean shoes before reuse. If irritation Hazardous skin contact
: Wash with a disinfectant soap and cover skin with an anti-bacterial Inhalation
: If inhaled, remove to fresh air and allow victim to rest. Get medical Hazardous inhalation
: If inhaled, remove victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If breathing is laboured, give oxygen If not breathing apply artificial respiration. Get medical attention. Ingestion
: DO NOT induce vomiting unless directed to do so by medical personnel. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible indication that the toxic material was ingested; the absence of such signs, however, s not conclusive. Loosen tight clothing such as a collar, tie, belt or waistband. If not breathing apply artificial Hazardous ingestion
Notes to physician
: Support respiratory and cardiovascular function.

SMALL FIRE: Obtain advice on use of water. Use DRY chemical LARGE FIRE: Use alcohol foam, water spray or fog. DO NOT USE WATER. Cool containing vessels with water jet on order to prevent pressure build-up, autoignition or explosion. Protective clothing (fire)
: Wear MSHA/NIOSH self-contained respirator or equivalent and full protective gear. Special remarks on fire hazards
: Vapour may travel considerable distance to source of ignition and flash back. When heated to decomposition it emits acrid smoke and irritating fumes. Cool containers with flooding quantities of water until well after fire is out. Special remarks on explosive
: Vapour explosion hazard indoors, outdoors and in sewers. Vapors may form explosive mixtures with air. Containers may explode when heated. Most vapours are heavier than air; they will spread along the ground and collect in low confined areas (sewers, basements, tanks).
Small spill or leak
: Dilute with water and mop up, or absorb with an inert dry material and place in an appropriate waste disposal container. Large spill or leak
: Flammable Liquid.
Keep away from heat. Keep away from sources of Ignition. Stop leak if without risk. Absorb with DRY earth, sand or other non-combustible material. Do not touch spilled material. Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all sources of ignition. Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with local authorities.
: Keep locked up. Keep away from heat and sources of ignition. Ground all equipment containing material. DO NOT ingest. DO NOT breath gas, vapour, fumes or spray. In case of inadequate ventilation, use suitable respiratory equipment. If ingested, seek medical advice immediately and show the container or the label. Avoid contact with skin and eyes. Keep away from incompatibles such as oxidizing agents, acids, alkalis, and moisture. : Flammable materials should be stored in a separately safety storage cabinet or room. Keep container in a cool, well-ventilated area. A refrigerated room would be preferable for materials with a flash point lower than 37.8ºC (100ºF). Keep container tightly closed and sealed until ready for use. Ground all equipment containing material. Keep away form heat. Avoid all possible sources of ignition (spark of flame).
EXPOSURE CONTROLS, PERSONAL PROTECTION
: Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapour below their respective threshold limit values. Ensure that eyewash stations and safety showers are proximal to the work-station location. Personal protection
: Vapour and dust respirator. Be sure to use an MSHA/NIOSH approved respirator equivalent. Wear appropriate respirator when ventilation is Protective clothing
: Splash goggles. Lab coat. Vapor respirator. Butyl gloves. Personal protection in case of large : Splash goggles. Full suit. Vapor and dust respirator. Boots. Gloves.
A self-contained breathing apparatus should be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling the product. Product name
