Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
First-aid measures
Emergency measure - Inhalation: Seek medical attention.
Emergency measure - Eyes: Immediately flush eyes for fifteen minutes with water. If
irritation continues, seek medical attention.
Emergency measure - Skin: Remove contaminated clothing and wash skin with soap and
water. If irritation and/or allergic reaction develops, seek
medical advice.
Emergency measure - Ingestion: Seek medical attention.
Fire-fighting measures
Recommended extinguishing agent: For small fires, use carbon dioxide or dry chemical. For
large fires, use water spray or alcohol-type aqueous
film-forming foam (AFFF)
Product arising from burning: Carbon monoxide, phenol and acetic acid.
Product determined by test: N
Protective equipment: Fire-fighters should wear self-contained breathing apparatus
(SCBA) and complete personal protective equipment when
exposed to products of combustion.
Accidental release measures
Emergency measures in case of spillage: Protective clothing and respirator should be worn. Do not
allow eye or skin contact. Do not breathe vapour. Eliminate
ignition sources. Place leaking containers in
well-ventilated area. Contact regulatory agencies to
determine acceptable clean-up levels. Absorbed spilled
liquids, collect and place in suitable container for
disposal. The spill area should then be washed and
ventilated. Consult the Environment Agency.
Handling and storage
Handling: Handle with extreme caution. Do not get in eyes on skin or
on clothing. Do not breathe vapour or mist. Wear suitable
chemical resistant gloves. Gloves should be changed
periodically as permeation time was found to be about 90
minutes with some nitrile gloves. Utilise protective
equipment to minimise all exposure. Handle compound in a
laboratory fume hood whenever possible. When transferring,
follow proper grounding procedures. Wash thoroughly with
soap and water after handling. Work clothes should be
laundered daily.
Use a NIOSH-approved full-facepiece respirator with
canisters or cartridges specifically approved for organic
vapours/acid gases.
Storage: Refrigeration is recommended for storage (5-10°C). Keep away
from heat, sparks and flames.
Protect from light and moisture.
Keep in original tightly closed containers when not in use.
Use with adequate ventilation.
Do not enter storage area that is not adequately ventilated.
Packaging of the substance and or preparation: 55 gallon steel composite drums or drums made of HDPE.
Recommend storage temperatures are between 5°C and 10°C.

Special provisions / remarks
- Remarks:
- Transport code: UN 3082
Transport: 4-ASM is typically shipped in refrigerated trailers or
insulated tank trucks (in the U.S). Since only 55 gallon
drums of the material will be shipped to EU countries,
refrigerated trailers are the preferred transport vehicles.

Exposure controls / personal protection
Stability and reactivity
Danger other than fire: CHEMICAL STABILITY:- Chemically stable, will polymerize
rapidly and exothermically in the presence of free-radical
initiators.
INCOMPATIBLE MATERIALS AND CONDITIONS TO AVOID:-
Oxidising agents, free radical initiators, iron, copper,
strong aqueous and non-aqueous acids and bases and avoid
prolonged storage at elevated temperatures.
HAZARDOUS POLYMERIZATION:-
Will not occur at ambient temperatures in the presence of
inhibitors.
Chemical reaction with water: Foam or water can cause frothing.
Dust explosion: Not applicable as the substance is a liquid.
Dust explosion determined by test: N
Disposal considerations
Industry - Possibility of recovery/recycling: This material cannot be recycled.
If sufficient quantity is recovered, it could be melt
crystallised or distilled under vacuum in the presence of
suitable inhibitors. If the material has been mixed with
reactive initiators, it is unlikely that the material can be
recovered.
Industry - Possibility of neutralisation: Controlled free radical polymerisation will produce
poly(4acetoxystyrene)(PAS). PAS is generally considered
harmless.
Industry - Possibility of destruction: controlled discharge: Not recommended
Industry - Possibility of destruction - incineration: Incineration is the preferred method of disposal.
Industry - Possibility of destruction - water purification: Not recommended.
Public at large - Possibility of recovery/recycling: Not applicable as the substance will not enter the public
domain.
