MSDS OF VINYL ACETATE

CHEMICAL FORMULA :CH3COOCH=CH2 GENERAL DESCRIPTION: Vinyl acetate monomer is a colorless liquid

with a low flash point. It has a characteristic odor. Vinyl acetate monomer is soluble in most organic solvents including chlorinated solvents , but is not soluble in water.

Uses: Its used as a raw material in production of EVA/LDPE. PHYSICAL AND CHEMICAL PROPERTIES : Molecular Weight : 86.09 Autoignition temperature : 402 °C LEL : 2.6 % UEL : 13.4 % Flash point : -8 °C (Open cup) Colourless. Odour Sweet. Boiling point / range : 72.5 °C Density : (934 g/cm3) Solubility Partially soluble in cold water

Potential Acute Health Effects: Very hazardous in case of skin contact (irritant), of eye contact

(irritant), of inhalation (lung irritant). Hazardous in case of ingestion. Slightly hazardous in case of skin

contact (permeator). Inflammation of the eye is characterized By redness,watering, and itching. Skin inflammation is characterized by itching, scaling, reddening, or, occasionally, blistering.

Potential Chronic Health Effects: Hazardous in case of inhalation (lung irritant). CARCINOGENIC

EFFECTS: Classified + (PROVEN) by OSHA. First Aid Measures: Eye Contact: Check for and remove any contact lenses. Immediately flush

eyes with running water for at least 15 minutes, keeping eyelids open. Cold water may be used. Do not use an eye ointment. Seek medical attention.

Skin Contact: After contact with skin, wash immediately with plenty of water.

Gently and thoroughly wash the contaminated skin with running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin. Cold water may be used.

Cover the irritated skin with an emollient. If irritation persists, seek medical attention. Wash contaminated clothing before reusing.

Serious Skin Contact: Wash with a disinfectant soap and cover the contaminated skin

with an anti-bacterial cream. Seek immediate medical attention. Inhalation: Allow the victim to rest in a well ventilated area. Seek

immediate medical attention. Serious Inhalation: Evacuate the victim to a safe area as soon as possible. Loosen

tight clothing such as a collar, tie, belt or waistband.

If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation. WARNING: It may be hazardous to the person providing aid to give mouth-to-mouth resuscitation when the inhaled material is toxic, infectious or corrosive. Seek medical attention.

Ingestion: Do not induce vomiting. 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, is not conclusive. Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth resuscitation. Seek immediate medical attention.

FIRE FIGHTING MEASURES: Extinguishing media Suitable extinguishing media: Use dry chemical, CO2, water spray (fog) or

foam Unsuitable extinguishing media: Do no use a water jet. Special hazards arising from the substance or mixture: Extremely flammable liquid. In a fire or if heated, a pressure increase will

occur and the contain may burst, with risk of subsequent explosion. The vapor/gas is heavier than air and will spread along the ground.

Vapors may accumulate in low or confined areas or travel a considerable distance to a source of ignition and flash back. Runoff to sewer may create fire or explosion hazard.

Advice for fire fighters: Special protective equipment for fire fighters: Fire fighters should

wear appropriate protective equipment and self-contained breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode.

Further information: Promptly isolate the scene by removing all persons from the vicinity of the incident if there is a fire. No action shall be taken involving an personal risk or without suitable training. Move containers from fire area if this can be done without risk. Use water spray to keep fire-exposed containers cool. Do not allow fire extinguishing water to contaminate surface or groundwater systems

Accidental release measures: Personal precautions, protective equipment and emergency

procedures: Advice for non-emergency personnel: Evacuate the danger zone;

follow emergency precautions. Secure emergency assistance immediately. Avoid contact with the material; do not breath vapors or aerosol. If possible, provide additional ventilation.

Advice for emergency responders: Do not take action without proper training and emergency equipment.. Evacuate surrounding areas. Eliminate all ignition sources including flares and all open flames. Avoid all contact with spiller material. Maintain adequate ventilation and wear appropriate respiratory protection.

Environmental precautions: Avoid dispersal of spilled material and runoff and contact with

soil, waterways, drains and sewers.

Methods and materials for containment: Stop leak if without risk. Contain and collect spillage using

appropriate personal protective equipment. Chemical-resistant, impervious gloves complying with an approved standard should be worn at all times when handing chemical products or if a risk assessment indicates this is necessary. Collect and contain spillage with non-combustible, absorbent material (e.g. sand, earth, vermiculite or diatomaceous earth) and place in a container for disposal according to local regulations.

Handling and storage: Precautions for safe handling: Observe all label precautions. Use appropriate personal

protective equipment . Eating, drinking and smoking should be prohibited in areas where this material is handled, stored and processed. Workers should wash hands and face before eating, drinking and smoking. Do not get in eyes or on skin or clothing. Do not ingest. Avoid breathing vapor or mist. Use only with adequate ventilation.

Wear appropriate respirator when ventilation is inadequate. Do not enter storage areas and confined spaces unless adequately ventilated. Use non-sparking tools. Take precautionary measures against electrostatic discharges. To avoid fire or explosion, dissipate static electricity during transfer by grounding and bonding containers and equipment before transferring material. Empty containers retain product residue and can be hazardous. Do not reuse container.

Advice on protection against fire and explosion: Keep away from flames and sources of ignition – including static.

Conditions for safe storage, including any incompatibilities: Store in a segregated and approved area. Store in original

container protected from direct sunlight in a dry, cool and well-ventilated area, away from incompatible materials and food.

Exposure controls:

Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or other engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits. The engineering controls also need to keep gas, vapor or dust concentrations below any lower explosive limits. Use explosion-proof ventilation equipment.

Engineering measures: Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or other engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits. The engineering controls also need to keep gas, vapor or dust concentrations below any lower explosive limits. Use explosion-proof ventilation equipment.

Individual protection measures: Hygiene measures: Wash hands, forearms and face thoroughly after

handling chemical products, before eating, smoking and using the lavatory and at the end of the working period. Appropriate techniques should be used to remove potentially contaminated clothing. Discard contaminated clothing or wash thoroughly before reusing. Ensure that eyewash stations and safety showers are close to the workstation location.

Eye/face protection: Safety eyewear complying with an approved standard should be used when a risk assessment indicates this is necessary to avoid exposure to liquid splashes, mists or dusts.

Hand protection: Chemical-resistant, impervious gloves complying with an approved standard should be worn at all times when when handling chemical products if a risk assessment indicates this is required.

Stability and reactivity: Reactivity: Vinyl acetate monomer reacts with polymerization initiators:

hydrogen peroxide, oxygen and peroxy compounds. Maintain hydroquinone inhibitors during storage and handling to prevent exothermic reactions.
