Storage and Handling

2P is classified under the Japanese Fire Services Act as a hazardous material, Class 4, Petroleums No.3 (4,000 liter quantity specified), water-soluble, Hazardous Rank III.
Since 2P is hygroscopic, if moisture content is to be controlled, it is important to keep storage containers tightly closed or under a dry nitrogen atmosphere.
When handling, protective equipment such as protective gloves and goggles should be worn. If contact with skin occurs, wash immediately with soap and water.
