|Warning|H400 (100%): Very toxic to aquatic life [Warning Hazardous to the aquatic environment, acute hazard]|P273, P391, and P501|Aggregated GHS information provided by 2 companies from 1 notifications to the ECHA C&L Inventory. Each notification may be associated with multiple companies.

Wear protective goggles and clothing.

Extinguishing media: carbon dioxide, dry chemical or foam. Evacuate areas down wind from fire. Use self-contained breathing apparatus.

Remove potential source of ignition, soak up with absorbent or treat as oil spill.

Zinc O,O-diisoalkyl dithiophosphates enter the environment through improper disposal of motor oils, greases and hydraulic fluids. They could also enter the environment from engine leaks, hydraulic pumps, gear boxes and torque converters if present in the fluids associated with these uses. /Zinc O,O-Diisoalkyl Dithiophosphates/

Aquatic: Once the compounds enter the aquatic environment, whether sorbed or dissolved at low concn, the zinc dialkyl dithiophosphates will probably dissociate./Zinc O,O-Diisoalkyl Dithiophosphates/

ZDDPs do not exist in used motor oils since they are broken down by engine action. ZDDPs were not detected in motor oils used for more than 3,000 miles./Zinc O,O-Diisoalkyl Dithiophosphates/

Cmpds may bioconcentrate unless metabolism is rapid. /Zinc O,O-Diisoalkyl Dithiophosphates/

These cmpds are expected to partition to the organic phase. They will probably sorb to humic matter and clay in the environ. The zinc is subject to exchange with other metals in natural water./Zinc O,O-Diisoalkyl Dithiophosphates/

Dermal exposure is likely to individuals handling lubricating oils and hydraulic fluids. /Zinc O,O-Diisoalkyl Dithiophosphates/|Consumers performing automobile oil changes may be exposed through use of lubricating oil. Automobile and other machinery mechanics will also be exposed./Zinc O,O-Diisoalkyl Dithiophosphates/

Wash skin or eyes with copious amt of water-see a physician.

Zinc, bis(O,O-diisodecyl phosphorodithioato-.kappa.S,.kappa.S')-: ACTIVE|Recommended for use at 0.5-1.5% volume to inhibit oxidation and as an anti-wear agent for industrial hydraulic oils, engine oils and tractor fluids.|Manufacturing is carried out with a batch process in a closed system. The plant is equipped with fume covers over all reaction vessels, storage tanks and filters. /Zinc O,O-Diisoalkyl Dithiophosphates/

Negative ion mass spectra were obtained from dialkyl dithiophosphates. Sensitivity of the method was such that detection of 1 ug of cmpd could be accomplished by selected ion monitoring, and 50-100 ug of cmpd was sufficient for scanning mass spectra. /Dialkyl Dithiophosphates/
