1 2
Blue Health 1 Can cause significant irritation.
Red Flammability 2 Must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur.
Yellow Instability 2 Readily undergoes violent chemical changes at elevated temperatures and pressures.
White Special
Note: NFPA ratings shown are for butyl methacrylate, CAS number 97-88-1.
(NFPA, 2010)
General Description
A colorless liquid with a mild odor. Less dense than water and insoluble in water. Hence floats on water. (USCG, 1999)

Hazards

The Hazard fields include special hazard alerts air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. The information in CAMEO Chemicals comes from a variety of data sources.
Reactivity Alerts
Air & Water Reactions
Insoluble in water.
Fire Hazard
Behavior in Fire: Containers may explode. (USCG, 1999)
Health Hazard
Inhalation may cause nausea because of offensive odor. Contact with liquid causes irritation of skin. Ingestion causes irritation of mouth and stomach. (USCG, 1999)
Reactivity Profile
BUTYL, DECYL, CETYL, EICOSYL METHACRYLATE is a mixture of four esters of methacrylic acid. Reacts with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction with basic (caustic) solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Polymerization may occur when heated, exposed to light or mixed with peroxides. Polymerization can generate large quantities of heat. (USCG, 1999).
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents

Response Recommendations

The Response Recommendation fields include isolation and evacuation distances, as well as recommendations for firefighting, non-fire response, protective clothing, and first aid. The information in CAMEO Chemicals comes from a variety of data sources.
Isolation and Evacuation
Excerpt from ERG Guide 130 Polymerizable warning [Flammable Liquids (Water-Immiscible / Noxious); polymerization hazard]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.

LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 feet).

FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020)
Firefighting
Fire Extinguishing Agents Not to Be Used: Water may be ineffective.

Fire Extinguishing Agents: Dry chemical, foam, carbon dioxide (USCG, 1999)
Non-Fire Response
Excerpt from ERG Guide 130 Polymerizable warning [Flammable Liquids (Water-Immiscible / Noxious); polymerization hazard]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor-suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean, non-sparking tools to collect absorbed material.

LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2020)
Protective Clothing
Self-contained respirator; impervious gloves; chemical splash goggles (USCG, 1999)
DuPont Tychem® Suit Fabrics

First Aid
INHALATION: Remove to fresh air, give oxygen or artificial respiration as required.

EYES: Flush with copious amounts of water for 15 min. and consult physician.

SKIN: Wash with soap and water.

INGESTION: Induce vomiting; call a physician. (USCG, 1999)

Physical Properties

The Physical Property fields include properties such as vapor pressure and boiling point, as well as explosive limits and toxic exposure thresholds The information in CAMEO Chemicals comes from a variety of data sources.

Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
