| Regulatorische Informationen | Chemical: 2-Propenoic acid, 2-(diethylamino)ethyl esterThe New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.) |
| Gefahrenübersicht | Severely irritating to skin and eyes[SAX] External application to rabbit eyes scored 9 on a scale of 1-10 (10 being most severe) for degree of injury after 24 hours[HSDB] A corrosive substance that can cause injury to the skin, eyes, and respiratory tractMay cause immediate skin blisteringInhalation may cause chemical pneumonitis and pulmonary edemaMay cause skin sensitizationCan be absorbed through skin[MSDSonline] See ACRYLIC RESINS (MONOMERS). |
| NFPA Hazard Classification | 2 - Materials that, under emergency conditions, can cause temporary incapacitation or residual injury.2 - Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Materials would not under normal conditions form hazardous atmospheres with air, but under high ambient temperatures or under moderate heating could release vapor in sufficient quantities to produce hazardous atmospheres with air.1 - Materials that in themselves are normally stable but that can become unstable at elevated temperatures and pressures. |

| Skin, Eye, and Respiratory Irritations | THE LOWER-MOL-WT ESTERS OF ACRYLIC ACIDS ARE IRRITANTS TO SKIN, EYES & MUCOUS MEMBRANES. /ACRYLIC ACID ESTERS/A severe skin and eye irritant. |
| Lagerbedingungen | 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. ... The acrylic esters may be stored in mild or stainless steel, or aluminum. /Acrylic acid & derivatives/ |
| Entsorgungsverfahren | 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. |
| Preventive Measures | 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 & SELF-CONTAINED RESP PROTECTIVE APPARATUS SHOULD BE AVAILABLE FOR USE OF THOSE WHO MAY HAVE TO RESCUE PERSONS OVERCOME BY FUMES. /ACRYLIC ACID & DERIVATIVES/Protection required for safe handling of acrylic acid and esters commonly includes use of impervious gloves, shoe soles, and clothingsplash-proof goggles ... /Acrylic acid & derivatives/ |

HUMAN SIGNS & SYMPTOMS FOLLOWING INGESTION OF ACRYLIC MONOMERS INCL COLLAPSE, SEVERE RESPIRATORY DIFFICULTIES, & CNS STIMULATION. ACUTE INHALATION OF HIGHER CONCN MAY CAUSE MARKED IRRITATION, SALIVATION, CONJUNCTIVAL IRRITATION, & PRONOUNCED PULMONARY IRRITATION OR EDEMA. PROLONGED SKIN OR EYE CONTACT MAY RESULT IN SEVERE TISSUE DAMAGE. THE PATHOLOGY FROM SINGLE EXPOSURE IS NONSPECIFIC, CONTRARY TO REPEATED EXPOSURE EFFECTS, WHICH INCL PULMONARY CONGESTION OR HEMORRHAGE & CLOUDY SWELLING OF LIVER & KIDNEY. /ACRYLATES/ |

The most severely injurious substances have been rated 10.Contact sensitivity was produced in guinea pigs with mono-, di-, and tri- acrylate compounds. /Mono-, di-, and tri- acrylate compounds/ |
| Antidote and Emergency Treatment | Basic treatment: Establish a patent airway. Suction if necessary. Encourage patient to take deep breaths. Watch for signs of respiratory insufficiency and assist ventilations if necessary. 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 ... . /Irritating materials/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. Early intubation at the first sign of upper airway obstruction may be necessary. Positive-pressure ventilation techniques with a bag-valve mask device may be beneficial. Monitor cardiac rhythm and treat arrhythmias if necessary ... . Start an IV with D5W TKO /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 ... . Treat seizures with diazepam (Valium) ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Irritating materials/ |

Rodrigues et al. prepared novel temperature and pH-responsive copolymers of [2-(acryloyloxy)ethyl] trimethylammonium chloride (AEtMACl) and 2-(diethylamino)ethyl acrylate (DEAEA) by RAFT polymerization. Such copolymers show a volume phase transition temperature that explains the excellent performance of hydrogels of the same monomers, selected among 600 monomer combinations, to release cultured stem cells using only a mild temperature stimulus[1].
