SMALL SPILLS AND LEAKAGE: If you spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION. Then, use absorbent paper to pick up all liquid spill material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol followed by washing 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.

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.

Incineration: It should be atomized into an incinerator and combustion may be improved by mixing with a more flammable solvent (acetone or benzene).

Toxicology and carcinogenesis studies of technical grade diglycidyl resorcinol ether (81 % pure) were conducted by admin the chemical in corn oil by gavage to groups of 50 male and 50 female F344/N rats at doses of 25 or 50 mg/kg and to groups of 50 male and female B6C3F1 mice at doses of 50 or 100 mg/kg. A supplemental study of similar design in male and female rats (0 or 12 mg/kg) was started approximately 12 months later because of high mortality in the 50 mg/kg dose groups. Doses were administered five times per week for 103 weeks. Groups of 50 rats and 50 mice of each sex received corn oil by gavage on the same dosing schedule and served as vehicle controls. ... Under the conditions of these 2-year gavage studies, technical grade diglycidyl resorcinol ether caused hyperkeratosis and hyperplasia of the forestomach in rats and mice. DGRE was carcinogenic for male and female F344/N rats and for male and female B6C3Fl mice, causing both benign and malignant neoplasms of the forestomach. Levels of Evidence of Carcinogenicity: Male Rats: Positive; Female Rats: Positive; Male Mice; Positive; Female Mice: Positive.
