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.

...Can react with oxidizing materials.|Glycol ethers, glycols, ketones, and alcohols undergo violent decomposition in contact with 68-72% perchloric acid

Diethylene glycol monoethyl ether is an indirect food additive for use only as a component of adhesives.

If material on fire or involved in fire: Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use "alcohol" foam, dry chemical or carbon dioxide. Keep run-off water out of sewers and water sources.

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.|Excessive exposure to inhaled mist or vapor should, in view of its low volatility, be readily controllable by ordinary precautions, but excessive contact with skin should be strictly avoided.|If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard.|Personnel protection: Avoid breathing vapors. Keep upwind. ... Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water.

The liquid is moderately irritating to the eye ...

Collect leaking liquid in sealable containers. Wash away remainder with plenty of water.

Separated from strong oxidants. Ventilation along the floor.

No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20 °C.

The substance is mildly irritating to the eyes.

The substance defats the skin, which may cause dryness or cracking.

NO open flames. Above 96 °C use a closed system and ventilation.

Use ventilation.

Protective gloves.

This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Diethylene glycol monoethyl ether is produced, as an intermediate or final product, by process units covered under this subpart.

| 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.| 0 - Materials that in themselves are normally stable, even under fire conditions.

In a national survey, diethylene glycol monoethyl ether was detected in 5 of 21 industrial categories of wastewater effluents(1). Wastewater from the iron and steel industry contained diethylene glycol monoethyl ether at an average concn of 497 mg/L; 52,189 mg/l for printing and publishing; 175 mg/L for amusement and athletic goods; and 40 mg/L for pulp and paper; other categories included publicly owned treatment works(1).

INDOOR AIR: One of 8 sampling periods from March 2, 1987 to Dec 6, 1988 gave a mean concentration of 4.2 ug/cu m(1/19-3/7/88) for diethylene glycol monoethyl ether taken from the second floor of a telephone switching office in Neenah, WI(1). Diethylene glycol monoethyl ether was detected but not quantified in 1 of 44 emission samples from furniture(2).

Diethylene glycol monoethyl ether was found in air freshener but not in cologne, perfume or soap samples that were tested(1).
