WHMIS (Mercuric sulfate)

Workplace Hazardous Materials Information System

WHMIS 2015 classification - Note to reader

• Acute toxicity - oral - Category 31 2

• Skin corrosion/irritation - Category 13
• Strong acid: pH of a 1,6% solution = 1,57

• Serious eye damage/eye irritation - Category 13
• Strong acid: pH of a 1,6% solution = 1,57

• Specific target organ toxicity - repeated exposure - Category 14 5 6

• Health hazards not otherwise classified (corrosion) - Category 1

Danger

Toxic if swallowed (H301)
Causes severe skin burns and eye damage (H314)
Causes damage to organs through prolonged or repeated exposure (H372)
Causes severe damage to the respiratory tract

Ingredient disclosure

Comments: Due to the lack of data, classification regarding specific organ toxicity - repeated exposure (H372) was established by analogy to inorganic mercury compounds (Mercury II chloride).
