The effectiveness of phenolic inhibitors is dependent on the presence of oxygen and the monomers must be stored under air rather than an inert atmosphere. Temp must be kept low to minimize formation of peroxides and other products. Moisture may cause rust-initiated polymerization. /Acrylic acid & derivatives/

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

Suitable protective clothing and self-contained respiratory protective apparatus should be available for use of those who may have to rescue persons overcome by fumes. /acrylic acid and derivatives/

... 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: 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.|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.

Methacrylates are slightly to severely irritating to skin and eyes and are considered potential skin sensitizers. /Methacrylic acid & derivatives/

Small quantities of methacrylates may readily be metabolized by saponification into the alcohol and methacrylic acid. The latter may form an acetyl-coenzyme A derivative, which then enters the normal lipid metabolism. /Methacrylates/|Acrylates and methacrylates are detoxified predominantly via conjugation with glutathione via the Michael addition reaction or glutathione-S-transferase. They are also likely to be hydrolyzed via carboxylesterases. The lower molecular weight esters are rapidly metabolized and eliminated, therefore, will not likely cause cumulative toxicity. /Methacrylates/

Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if needed.

Thin-layer chromatography (TLC), polarography, and spectrometry are used for soln measurements. Methacrylates in air have been analyzed by TLC, polarography, and colorimetry. Polarography has been used for determination of any residual monomer in the polymer. /Methacrylic acid & derivatives/
