Releases of CERCLA hazardous substances are subject to the release reporting requirement of CERCLA section 103, codified at 40 CFR part 302, in addition to the requirements of 40 CFR part 355. Methyl 2-chloroacrylate is an extremely hazardous substance (EHS) subject to reporting requirements when stored in amounts in excess of its threshold planning quantity (TPQ) of 500 lbs.

... AT VERY LOW CONCN (5-10 PPM) THE VAPORS OF THIS MONOMER HAVE VERY IRRITATING ACTION ON EYES.

A severe skin irritant.

Fight fire from maximum distance. Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind; keep out of low areas. Ventilate closed spaces before entering them. Wear positive pressure breathing apparatus and special protective clothing.

(Non-Specific -- Poisonous Liquid, n.o.s.) Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind; keep out of low areas. Ventilate closed spaces before entering them. Remove and isolate contaminated clothing at the site. Stop leak if you can do so without risk. Use water spray to reduce vapors.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

IT IS NECESSARY TO TAKE STRONG PREVENTIVE MEASURES IN FACTORY, BOTH WITH REGARD TO SKIN & RESPIRATORY TRACT.

... Hazard is the generation of considerable exothermic heat in some of the reactions, so that high pressures & temp may develop. This danger... should be borne in mind when designing plant. Awareness of the dangers and of good engineering design are essential to safety. Employees should be instructed about the necessity of cleansing the skin if it is contaminated by materials which are irritants or skin-absorbed. With careful design, however, and complete enclosure of those processes where toxic chemicals or intermediates occur, dangerous exposures can be avoided. /Acrylic acid & derivatives/

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

For emergency situations, wear a positive pressure, pressure-demand, full facepiece self-contained breathing apparatus (SCBA) or pressure- demand supplied air respirator with escape SCBA and a fully-encapsulating, chemical resistant suit. (EPA, 1998)

SUITABLE PROTECTIVE CLOTHING & SELF-CONTAINED RESP PROTECTIVE APPARATUS SHOULD BE AVAILABLE FOR USE OF THOSE WHO MAY HAVE TO RESCUE PERSONS OVERCOME BY FUMES. /ACRYLIC ACID & DERIVATIVES/

IT IS ... A RESPIRATORY POISON, & BREATHING ITS VAPORS CAN CAUSE PULMONARY EDEMA. EVEN AT VERY LOW CONCN (5-10 PPM) THE VAPORS OF THIS MONOMER HAVE VERY IRRITATING ACTION ON EYES.

REPLACEMENT OF A CH3 GROUP ... BY A CHLORINE ATOM CONSIDERABLY INCREASES THE IRRITANT PROPERTIES.

Methyl-alpha-chloroacrylate is a strong vesicant; a trace on the skin causes large blisters.
