PFOS and PFOA for foaming agents
In principle, PFOS and PFOA are prohibited from manufacturing and importing under the Law Concerning the Examination and Manufacturing of Chemical Substances, but may still be included in foaming agents in fire extinguishing equipment.
If foaming agent containing PFOS or PFOA leaks due to damage to this equipment, etc., it falls under the emergency measures under the above-mentioned Ordinance on conservation, etc. of the living environment of Yokohama City. It is necessary to take measures such as prevention and report the details of the measures accordingly.
In addition, the outflow of foaming agents, including PFOS or PFOA, due to fire fighting activities, does not correspond to emergency measures under the ordinance, but please contact us to understand the outflow into the environment. In that case, "date and time of use / spill", "product name of foam disinfectant, content / content of PFOS or PFOA", "use / discharge of foam disinfectant", "surrounding situation" Please let us know.
Regarding PFOS and PFOA, various materials such as Q & A collection have been published in the country. For details, please see the "PFOS / PFOA" section of "Measures in the Event of an Accident".
