General Recommendations for Clean-up of Soot/Ash from the TCI of New York Facility Fire
The following procedures are intended for those areas that have a visible accumulation of soot and dust from the fire:
All exterior wash water should be hosed down with fresh water and cleared away from structures as best as possible. Wash water should also be diverted from vegetable gardens or areas where children may play.
Personal protection measures:
Protective clothing such as rubber gloves, long sleeves, long pants, closed toed shoes are recommended. If conditions are dusty or material is airborne, then the use of an N-95 particulate respirator is recommended. These respirators can be purchased at hardware or home centers.
Emergency Vehicles/Turn Out Gear:
Hose/wash affected exterior surfaces in close proximity to the TCI facility. The facility property has a liner under the property and surface ground direction will contain the effluent from the washing. Interiors of emergency vehicles can be vacuumed with High Efficiency Particulate (HEPA) vacuums or wet washed as appropriate.
If you have any questions please call your local or state health department.
