8.2 Appropriate engineering controlsHandle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.
8.3 Individual protection measures, such as personal protective equipment (PPE) Eye/face protectionSafety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protectionWear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
Based on pure culture data, p-terphenyl is expected to be resistant to aerobic biodegradation(SRC). Two bacterial strains of Alcaligenes and Acinetobacter, enriched on biphenyl or 4-chlorobiphenyl, were unable to utilize p-terphenyl as a sole carbon source during a four week period(1).
12.3 Bioaccumulative potentialAn estimated BCF value of 5900 was calculated for p-terphenyl(SRC), using a measured water solubility of 0.0179 mg/l(1) and a recommended regression-derived equation(2). According to a recommended classification scheme(3), this BCF value indicates that bioconcentration of p-terphenyl in aquatic organisms is high(SRC).
12.4 Mobility in soilThe Koc of p-terphenyl is estimated as approximately 40000(SRC), using an experimental water solubility of 0.0179 mg/l(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that p-terphenyl will be immobile in soil(SRC).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe 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.
Contaminated packagingContainers 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.
