    The soot that can be produced from a structure fire can be rather toxic to humans, and the type of material burned in the structure dictates how dangerous the abatement will be. VOC, heavy metals, formaldehyde etc., are hazardous and require the correct disposal to be set in place. There is...

    Rail vehicle maintenance facilities: F or S?

    My opinion would be F1; the normal repairs, but if the repair was on a tanker section carrying hazardous material, then the classification would change to an H classification. The airplane hanger repair is going to deal with aviation fuel, changing its designation from F1 to S1
