GefahrenübersichtMay polymerizeA skin irritantMay cause skin sensitization[MSDSonline] See ACRYLIC RESINS (MONOMERS).
Hazard Classes and CategoriesSkin Irrit. 2 (66.3%)
Skin, Eye, and Respiratory IrritationsMethacrylates are slightly to severely irritating to skin and eyes and are considered potential skin sensitizers. /Methacrylic acid & derivatives/
LagerbedingungenTo avoid photoinitiation of polymerization, all methacrylates should be stored with minimal exposure to light.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/

Anwendungen & Verwendung

Verwenden

Hexadecyl Methacrylate is a reagent in the synthesis of methacrylate copolymers and terpolymers which are used as lubricating oil pour point depressants.

EntsorgungsverfahrenSRP: 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 qualitypotential migration in soil or watereffects on animal, aquatic, and plant lifeand conformance with environmental and public health regulations.
Preventive Measures... 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.
Personal Protective Equipment (PPE)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/
Unerwünschte WirkungenSkin Sensitizer - An agent that can induce an allergic reaction in the skin.
Non-Human Toxicity Excerpts/LABORATORY ANIMALS: Developmental or Reproductive Toxicity/ Animal studies using rats revealed that some acrylates and methacrylates are embryotoxic. The doses of monomers used in the animal studies, however, were much higher than concentrations likely encountered by workers. /Acrylates and Methacrylates/
Antidote and Emergency TreatmentBasic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if needed. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool ... . Cover skin burns with dry sterile dressings after decontamination ... . /Poison A and B/Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in respiratory arrest. Positive pressure ventilation techniques with a bag valve mask device may be beneficial. Monitor cardiac rhythm and treat arrhythmias as necessary ... . Start an IV with D5W /SRP: "To keep open", minimal flow rate/. Use lactated Ringer's if signs of hypovolemia are present. Watch for signs of fluid overload. Consider drug therapy for pulmonary edema ... . For hypotension with signs of hypovolemia, administer fluid cautiously. Watch for signs of fluid overload ... . Treat seizures with diazepam (Valium) ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Poison A and B/
