General remarks <\/p>\n
Water hazard class 1 (German Regulation) (self-assessment via list) The substance is slightly hazardous to water. <\/p>\n
Do not allow undiluted or large quantities of product to come into contact with groundwater, waterways or sewage systems. <\/p>\n
Even extremely small amounts of product seeping into the ground can be dangerous to drinking water<\/p>\n
Do not discharge materials into the surrounding environment without government permission. <\/p>\n<\/p>\n
