WHMIS (Cobaltous nitrate)

Workplace Hazardous Materials Information System

WHMIS 2015 classification - Note to reader

• Oxidizing solids - Category 21

• Acute toxicity - oral - Category 42

• Serious eye damage/eye irritation - Category 13

• Respiratory sensitization - Category 14

• Skin sensitization - Category 15

• Carcinogenicity - Category 26

• Specific target organ toxicity - repeated exposure - Category 2

Danger

May intensify fire; oxidizer (H272)
Harmful if swallowed (H302)
Causes serious eye damage (H318)
May cause allergy or asthma symptoms or breathing difficulties if inhaled (H334)
May cause allergic skin reaction (H317)
Suspected of causing cancer (H351)
May cause damage to organs through prolonged or repeated exposure (H373)

Ingredient disclosure

Comments: Due to the lack of data, classifications for respiratory sensitization (H334) and specific organ toxicity - repeated exposure (H372) have been established by analogy to Cobalt dichloride.
