2 to 3. 2= slightly toxic: probable oral lethal dose (human) 5-15 g/kg, between 1 pint & 1 qt for 70 kg person (150 lb). 3= moderately toxic: probable oral lethal dose (human) 0.5-5 g/kg, between 1 oz & 1 pint (or 1 lb) for 70 kg person (150). terphenyl
An intragastric dose of (14)c labeled o-terphenyl was rapidly absorbed, distributed, and almost completely excreted within 48 hr, in the rat mainly through the bile and in the rabbit mainly through urinary excretion. temporary accum in the liver peaked at 4.5 hr in the mouse and was completely cleared in 1 wk.
Carbon dioxide, dry chemical.
Combustible.
Use water spray, dry powder, carbon dioxide.
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Vacuum spilled material with specialist equipment. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

1. Remove all ignition sources. 2. Ventilate area of spill or leak. 3. For small quant, sweep onto paper or other suitable material, place in an appropriate container and burn in a safe place (such as a fume hood). Large quant may be reclaimed; however, if this is not practical, use a procedure similar to that for small quant. Terphenyls
NO open flames. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Store the container tightly closed in a dry, cool and well-ventilated place. Store apart from foodstuff containers or incompatible materials.

O-terphenyl is a colorless or light-yellow solid. mp: 58-59° C, bp: 337°C. Density: 1.16 g/cm3. Insoluble in water. Usually shipped as a solid mixture with its isomers m-terphenyl and p-terphenyl that is used as a heat-transfer fluid.

Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
A waste water mixture containing 33% m-terphenyl, 17% o-terphenyl, and 1.5% thermip (a heat exchanger consisting of naphthalene, methyl naphthalene diphenyl, and alkyl derivatives of naphthalene) was inoculated with a mixture of three bacteria, two Pseudomonas and one Acinetobacter species. After 130 hours aerobic incubation, 100% of the o-terphenyl remained(1).
A BCF of 590 for o-terphenyl was measured in goldfish(1). An estimated BCF value of 550 was calculated for o-terphenyl(SRC), using a measured water solubility of 1.24 mg/l(2) and a recommended regression-derived equation(3). According to a recommended classification scheme(4), these BCF values indicate that bioconcentration of o-terphenyl in aquatic organisms should be an important fate process(SRC).
The Koc of o-terphenyl is estimated as approximately 3900(SRC), using an experimental water solubility of 1.24 mg/l(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that o-terphenyl has only slight mobility in soil(SRC).

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
