    Class 4 dangerous goods include flammable solids, substances liable to spontaneous combustion and substances which, in contact with water, emit flammable gases. There are three sub-divisions: Division 4.1: Flammable solids.

    What is a Class 8 product?

    Class 8 substances (corrosive substances) are substances which, by chemical action, will cause severe damage when in contact with living tissue, or, in the case of leakage, will materially damage, or even destroy, other goods or the means of transport.

    What is the most hazardous substance?

    1. Botulinum toxin. Scientists differ about the relative toxicities of substances, but they seem to agree that botulinum toxin, produced by anaerobic bacteria, is the most toxic substance known. Its LD50 is tiny – at most 1 nanogram per kilogram can kill a human.

  • Slippery/ debris littered floors.
  • Improperly secured machinery.
  • Poorly maintained equipment.
  • Bad lighting.
  • Dangerous stairways.
  • Large obstacles left in the path of workers or blocking exits.
  • Trailing extension cords.

    What is a Class 5 Oxidizer?

    Class 5.1 oxidizers are materials, which by yielding oxygen, can cause or enhance the combustion of other materials. Loosely speaking, they're catalysts to setting something else on fire—whether to good or bad effect. They're used as chemical accelerators, activators, catalysts, curing agents, hardeners, and more.
