Also can bathe with affluence of water, ablution baptize adulterated into the wastewater system. Large spills: amalgam barricade or dig a hole. Pump is transferred to the catchbasin or absolute collector, a abode to accord with recycled or transported to the decay disposal. Blaze cadre have to abrasion a respirator ( abounding cover) or abreast respirator, abrasion full-body blaze careful clothing, blaze in the wind. As far as accessible the argosy to an accessible area. Keep the blaze cooling baptize container, until the end of the fire. In the barge in blaze arena if birthmark or from complete burden abatement device, have to abandon immediately. Abolition media: baptize spray, foam, dry powder, carbon dioxide, sand. Prohibit the use of acid-base blaze abolition agent. : stored in a cool, aerial warehouse. Away from fire, calefaction source. Couvin should not beat 30 ℃.
