4. FIRST AID MEASURES

Inhalation: Move to fresh air. If breathing is irregular or stopped, administer artificial respiration. 

Immediate medical attention is required.

Skin contact: Take off all contaminated clothing immediately. Wash off immediately with soap and 

plenty of water. Consult a physician. Wash contaminated clothing before re-use.

Eye contact: Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. 

Immediate medical attention is required.

Ingestion: Never give anything by mouth to an unconscious person. If a person vomits when lying on 

his back, place him in the recovery position. Drink 1 or 2 glasses of water. Call a physician 

immediately.

5. FIRE-FIGHTING MEASURES

Flash point -4 °C ( 25 °F ) Ethyl acetate

Lower explosion limit 2.2 %(V)Ethyl acetate

Upper explosion limit 11.4 %(V)Ethyl acetate

Thermal decomposition Heating or fire conditions liberates toxic gas., Carbon oxides

Suitable extinguishing media:Foam

Carbon dioxide (CO2)

Dry powder

Water spray

Specific hazards during fire fighting: Vapors can travel to a source of ignition and flash back. 

Heated material can form flammable or explosive vapors with air. Closed containers may rupture via 

pressure build-up when exposed to fire or extreme heat.

Special protective equipment for fire-fighters: Wear self-contained breathing apparatus and 

protective suit.

Further information: For safety reasons in case of fire, containers should be stored separately in 

closed containments.

Cool closed containers exposed to fire with water spray.

6. ACCIDENTAL RELEASE MEASURES

Personal precautions

Remain upwind.

Avoid breathing smoke.

Remove all sources of ignition.

Environmental precautions

Do not flush into surface water or sanitary sewer system.

Methods for cleaning up

Evacuate personnel to safe areas.

Remove all sources of ignition.

Ensure adequate ventilation.

Contain spillage, and then collect with non-combustible absorbent material, (e.g. sand, earth, 

diatomaceous earth, vermiculite) and place in container for disposal according to local / national 

regulations (see section 13).

7. HANDLING AND STORAGE

Handling

Provide sufficient air exchange and/or exhaust in work rooms. Avoid exceeding of the given 

occupational exposure limits (see section 8). In case of insufficient ventilation, wear suitable 

respiratory equipment. Wear personal protective equipment. For personal protection see section 8. 

CONTAINERS MAY BE HAZARDOUS WHEN EMPTY. Since emptied containers retain product 

residue follow all MSDS and label warnings even after container is emptied.

Storage

Storage conditions: Material can burn; limit indoor storage to approved areas equipped with 

automatic sprinklers. Keep container tightly closed in a dry and well-ventilated place. Keep away from 

heat and sources of ignition. Electrical installations / working materials must comply with the 

technological safety standards.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Exposure limit(s)

Exposure limits are listed below, if they exist.

Component Regulation Type of listing Value

Ethyl acetate Rohm and Haas TWA 150 ppm

Rohm and Haas STEL 300 ppm

ACGIH TWA 400 ppm

NIOSH/GUIDE REL 1,400 mg/m3 400 ppm

OSHA_TRANS PEL 1,400 mg/m3 400 ppm

Z1A TWA 1,400 mg/m3 400 ppm

Eye protection: Use chemical splash goggles (ANSI Z87.1 or approved equivalent). Eye protection 

worn must be compatible with respiratory protection system employed.

Hand protection: Chemical-resistant gloves should be worn whenever this material is handled. The 

glove(s) listed below may provide protection against permeation. (Gloves of other chemically resistant 

materials may not provide adequate protection): Neoprene gloves butyl-rubber

Respiratory protection: A respiratory protection program meeting OSHA 1910.134 and ANSI Z88.2 

requirements or equivalent must be followed whenever workplace conditions warrant a respirator‟s 

use. None required if airborne concentrations are maintained below the exposure limit listed in 

Exposure Limit Information. Up to 1000 ppm organic vapor: Wear a properly fitted NIOSH approved 

(or equivalent) full-facepiece, air-purifying respirator, OR full facepiece, airline respirator in the 

pressure demand mode. Above 1000 ppm organic vapor or Unknown: Wear a properly fitted NIOSH 

approved (or equivalent) self-contained breathing apparatus in the pressure demand mode, OR fullfacepiece, airline respirator in the pressure demand mode with emergency escape provision.

Protective measures: Facilities storing or utilizing this material should be equipped with an eyewash 

facility and a safety shower.

Engineering measures: Use explosion-proof local exhaust ventilation with a minimum capture 

velocity of 100 ft/min (0.5 m/sec) at the point of vapor evolution. Refer to the current edition of 

Industrial Ventilation: A Manual of Recommended Practice published by the American Conference of 

Governmental Industrial Hygienists for information on the design, installation, use, and maintenance of 

exhaust systems.
