Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)

Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above. FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

SMALL SPILLS AND LEAKAGE: If you should spill this chemical, use absorbent paper to pick up all liquid spill material. Seal the absorbent paper, as well as any of your clothing which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Wash any surfaces you may have contaminated with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned. STORAGE PRECAUTIONS: You should protect this material from exposure to light, and store it under ambient temperatures. (NTP, 1992)

MINIMUM PROTECTIVE CLOTHING: If Tyvek-type disposable protective clothing is not worn during handling of this chemical, wear disposable Tyvek-type sleeves taped to your gloves. RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with a combination filter cartridge, i.e. organic vapor/acid gas/HEPA (specific for organic vapors, HCl, acid gas, SO2 and a high efficiency particulate filter). Splash proof safety goggles should be worn while handling this chemical. Alternatively, a full face respirator, equipped as above, may be used to provide simultaneous eye and respiratory protection. (NTP, 1992)|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/

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 ... produce slight to moderate skin and eye irritation ... depending upon volatility, these materials also may be sensory irritants. /Methacrylic acid & derivatives/

Diethylene glycol diacrylate's production and use as a radiation cure for UV, beta, and gamma radiation and its use in coatings or adhesive fields(1) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that diethylene glycol diacrylate will have very high mobility in soil(SRC). Volatilization of diethylene glycol diacrylate may be important from moist soil surfaces(SRC) given an estimated Henry's Law constant of 9.5X10-10 atm-cu m/mole(SRC), using a recommended regression equation(3). Volatilization from dry soil surfaces(SRC) is not expected to be significant based on an estimated vapor pressure of 4.1X10-2 mm Hg(SRC), determined from a fragment constant method(4). Hydrolysis is expected to be a major fate process for this compound in moist soil(SRC). A base-catalyzed second-order rate constant of 3.7 l/mol-sec(SRC) was estimated using a structure estimation method(5); this corresponds to half-lives of 22 and 2 days at pH values of 7 and 8, respectively(5,SRC).|AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 10(SRC), determined from a structure estimation method(2), indicates that diethylene glycol diacrylate should not adsorb to suspended solids and sediment in water(SRC). Diethylene glycol diacrylate is not expected to volatilize from water surfaces(1,SRC) based on an estimated Henry's Law constant of 9.5X10-10 atm-cu m/mole(SRC), developed using a fragment constant estimation method(3). According to a classification scheme(5), an estimated BCF value of 3(1,SRC), from an estimated log Kow(4,SRC), suggests that bioconcentration in aquatic organisms is low(SRC). Hydrolysis is expected to be a major fate process for this compound in water(SRC). A base-catalyzed rate constant of 3.707 l/mol-sec(SRC) was estimated using a structure estimation method(6); this corresponds to half-lives of 22 and 2 days at pH values of 7 and 8, respectively(6,SRC).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), diethylene glycol diacrylate, which has an estimated vapor pressure of 4.1X10-2 mm Hg at 25 °C(2,SRC), may exist solely as a vapor in the ambient atmosphere. Vapor-phase diethylene glycol diacrylate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be about 20 hours(3,SRC).

The rate constant for the vapor-phase reaction of diethylene glycol diacrylate with photochemically-produced hydroxyl radicals has been estimated as 5.0X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1,SRC). This corresponds to an atmospheric half-life of about 20 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1,SRC). A base-catalyzed rate constant of 3.707 l/mol-sec(SRC) was estimated using a structure estimation method(2); this corresponds to half-lives of 22 and 2 days at pH values of 7 and 8, respectively(2,SRC).

An estimated BCF value of 3 was calculated for diethylene glycol diacrylate(SRC), using an estimated log Kow of 0.84(1,SRC) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for diethylene glycol diacrylate can be estimated to be about 10(SRC). According to a recommended classification scheme(2), this estimated Koc value suggests that diethylene glycol diacrylate has very high mobility in soil(SRC).

The Henry's Law constant for diethylene glycol diacrylate is estimated as 9.5X10-10 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This value indicates that diethylene glycol diacrylate will be essentially nonvolatile from water surfaces(2,SRC). Diethylene glycol diacrylate's estimated values for vapor pressure, 4.1X10-2 mm Hg(3,SRC) and Henry's Law constant(1,SRC) indicate that volatilization from dry and moist soil surfaces should not occur(SRC).

Occupational exposure to diethylene glycol diacrylate during its production or use in the manufacture of other products may be through respiratory and dermal routes(SRC). The general population may be exposed to this compound through its use as a radiation cure(1) or through contact with products containing diethylene glycol diacrylate(SRC).

SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin and eyes, blistering and sensitization. ACUTE/CHRONIC HAZARDS: This compound is an irritant of the skin and eyes. When heated to decomposition it emits acrid smoke, acids and noxious gases. (NTP, 1992)

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. Corrosive chemicals will destroy the membranes of the mouth, throat, and esophagus and, in addition, have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. Transport the victim IMMEDIATELY to a hospital. (NTP, 1992)
