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 any 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.
Hazardous thermal
decomposition products
Specific hazards arising
from the chemical
Decomposition products may include the following materials:
carbon dioxide
carbon monoxide
Highly flammable liquid and vapor. Runoff to sewer may create fire or explosion
hazard. In a fire or if heated, a pressure increase will occur and the container may
burst, with the risk of a 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.
Fire-fighters should wear appropriate protective equipment and self-contained
breathing apparatus (SCBA) with a full face-piece operated in positive pressure
mode.

Section 6. Accidental release measures
Environmental precautions
Stop leak if without risk. Move containers from spill area. Use spark-proof tools and
explosion-proof equipment. Approach release from upwind. Prevent entry into
sewers, water courses, basements or confined areas. Wash spillages into an
effluent treatment plant or proceed as follows. Contain and collect spillage with non-
combustible, absorbent material e.g. sand, earth, vermiculite or diatomaceous earth
and place in container for disposal according to local regulations (see Section 13).
Dispose of via a licensed waste disposal contractor. Contaminated absorbent
material may pose the same hazard as the spilled product. Note: see Section 1 for
emergency contact information and Section 13 for waste disposal.
:Avoid dispersal of spilled material and runoff and contact with soil, waterways,
drains and sewers. Inform the relevant authorities if the product has caused
environmental pollution (sewers, waterways, soil or air).
Large spill :
Stop leak if without risk. Move containers from spill area. Use spark-proof tools and
explosion-proof equipment. Dilute with water and mop up if water-soluble.
Alternatively, or if water-insoluble, absorb with an inert dry material and place in an
appropriate waste disposal container. Dispose of via a licensed waste disposal
contractor.

Section 8. Exposure controls/personal protection
Ingredient name Exposure limits
Hand protection Chemical-resistant, impervious gloves complying with an approved standard should
be worn at all times when handling chemical products if a risk assessment indicates
this is necessary. Considering the parameters specified by the glove manufacturer,
check during use that the gloves are still retaining their protective properties. It
should be noted that the time to breakthrough for any glove material may be
different for different glove manufacturers. In the case of mixtures, consisting of
several substances, the protection time of the gloves cannot be accurately
estimated.
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,
gases or dusts. If contact is possible, the following protection should be worn,
unless the assessment indicates a higher degree of protection: chemical splash
goggles.

Environmental exposure
controls
:Emissions from ventilation or work process equipment should be checked to ensure
they comply with the requirements of environmental protection legislation. In some
cases, fume scrubbers, filters or engineering modifications to the process
equipment will be necessary to reduce emissions to acceptable levels.
Appropriate engineering
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.
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.
Contaminated work clothing should not be allowed out of the workplace. Wash
contaminated clothing before reusing. Ensure that eyewash stations and safety
showers are close to the workstation location.

. FIRST AID
SKIN: Wash with plenty of water. Remove contaminated clothing and do not reuse until laundered.
EYES: Wash eyes with plenty of water, holding eyelids open. Seek medical assistance promptly if there is irritation.
INHALATION: Remove from contaminated area promptly. CAUTION: Rescuer must not endanger himself! If breathing
stops, administer artificial respiration and seek medical aid promptly.
INGESTION: Give plenty of water to dilute product. Do not induce vomiting (NOTE below). Keep victim quiet. If vomiting
occurs, lower victim s head below hips to prevent inhalation of vomited material. Seek medical help promptly.
Inadvertent inhalation of vomited material may seriously damage the lungs. The danger of this is greater than the risk of poisoning through absorption of this
relatively low-toxicity substance. The stomach should only be emptied under medical supervision, and after the installation of an airway to protect the lungs.

o
C, & away from substances named in Part 10.
Take extreme care to avoid
sparks. Use only non-sparking bronze or aluminium hand tools. All electrical and mechanical equipment (including lighting,
switchgear & forklift trucks) used with or around this product must be explosion-proof. Although this product cannot retain a
static charge on agitation or transfer from one container to another, its flash point is low & it is prudent to ground or electrically
bond the source container, receiving container, & transfer pump before transferring contents. Avoid splashing by ensuring the
product nozzle is below the surface in the receiving container.
Never use compressed air to transfer this product. Pressurised air with ~8% oxygen can be used to transfer product
(consult the safe handling manuals below)
If stored over one month, check titre of inhibitor (hydroquinone 100-200ppm is often used). Replenish as necessary. The
inhibitor requires oxygen to work properly! Never store the product under nitrogen!
Avoid breathing product vapour. Use with adequate ventilation. If dealing with a spill, and ventilation is impossible or
impractical, wear a suitable respirator with an organic vapour cartridge. If the spill is extensive, wear an air-supplied respirator.
Never cut, drill, weld or grind on or near this container. Empty containers may contain a flammable vapour! Avoid
contact with skin and wash work clothes frequently. An eye bath and safety shower must be available near the workplace.

Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best
demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Methyl
methacrylate is produced, as an intermediate or a final product, by process units covered under this subpart. Listed as a hazardous air pollutant (HAP) generally known or suspected to
cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA
is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Methyl methacrylate is included on
this list.
State Drinking Water Guidelines: Florida 25 ug/L
Clean Water Act Requirements: Methyl methacrylate is designated as a hazardous substance under section 311(b)(2)(A) of the Federal Water Pollution Control Act and further
regulated by the Clean Water Act Amendments of 1977 and 1978. These regulations apply to discharges of this substance. This designation includes any isomers and hydrates, as well as any solutions and mixtures containing this substance.
CERCLA Reportable Quantities: Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this
designated hazardous substance, in an amount equal to or greater than its reportable quantity of 1000 lb or 454 kg. The toll free number of the NRC is (800) 424-8802. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV.D.3.b).
TSCA Requirements: Pursuant to section 8(d) of TSCA, EPA promulgated a model Health and Safety Data Reporting Rule. The section 8(d) model rule requires manufacturers,
importers, and processors of listed chemical substances and mixtures to submit to EPA copies and lists of unpublished health and safety studies. Methyl methacrylate is included on this list. Effective date 4/13/89; Sunset date: 6/30/98.
RCRA Requirements: As stipulated in 40 CFR 261.33, when methyl methacrylate, as a commercial chemical product or manufacturing chemical intermediate or an off-specification
commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to Federal and/or State hazardous waste regulations. Also defined as a hazardous waste is any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5).
FDA Requirements: Homopolymers and copolymers of methyl methacrylate are an indirect food additive for use only as a component of adhesives.
