WHMIS (Thallium)

Workplace Hazardous Materials Information System

WHMIS 2015 classification - Note to reader

• Combustible dusts - See comments below1 2

• Acute toxicity - oral - Category 23 4

• Specific target organ toxicity - repeated exposure - Category 24 5 6 7 8 9 10

Danger

Fatal if swallowed (H300)
May cause damage to organs through prolonged or repeated exposure (H373)

Ingredient disclosure

Comments:

This product could belong to the hazard class "Combustible dust", based on various factors related to the combustibility and explosiveness of its dust, including composition, shape and size of the particles.

Due to the lack of data, classification regarding specific organ toxicity - repeated exopsure (H373) was established by analogy to soluble Thallium compounds (Thallous sulfate).
