Follow related laws and regulations during use. The laws and regulations are Japanese one.


Technical Measures

Work in accordance with laws and regulations related to the Industrial Safety and Health Act of Japan or your local rules. In Japan, Perchloroethylene is a class 2 special organic solvent as specified by the Ordinance on Prevention of Hazards due to Specified Chemical Substances.
Ventilate the work area well, and eliminate as much exhaust gas as possible using activated charcoal or other means.
Do not generate unnecessary vapor, which could cause the product to leak, overflow, or splatter.


Although the product is flame-retardant at room temperature, do not allow vapor to make contact with extremely hot temperature sources, such as naked flames or electric heaters. If the product makes contact with high temperatures, it will undergo thermal decomposition, releasing hydrogen chloride, carbon monoxide, phosgene, and other extremely toxic gases.
The product does not combust under normal conditions. However, if the concentration of oxygen grows higher than that of the air, take caution as it could combust even at normal temperatures.


Proper Storage Conditions

When storing the product in containers such as drums or oil tins,
store in a cool and well-ventilated area that can protect the product from rainwater and direct sunlight.
If the storage location is indoors, make sure that appropriate exhaust equipment is installed and keep the room at or below the recommended concentration.
Install flooring so that the product does not flow into public water areas, drainages, or underground, if by some chance the product should leak.
