WHMIS (Phosphorus pentasulfide)

Workplace Hazardous Materials Information System

WHMIS 2015 classification - Note to reader

• Flammable solids - Undefined category1 2 3 4 5
• This hazard class has been assigned according to the information obtained from the consulted scientific literature, but it does not allow to specify the hazard category.

• Substances which, in contact with water, emit flammable gases - Undefined category1 2 3 4 5
• This hazard class has been assigned according to the information obtained from the consulted scientific literature, but it does not allow to specify the hazard category.

• Combustible dusts - See comments below2 3 4 5

• Acute toxicity - oral - Category 46

• Acute toxicity - inhalation - Category 25 7 8
• Releases a fatal gas upon contact with water: Hydrogen

• Skin corrosion/irritation - Category 25 9 10

• Serious eye damage/eye irritation - Category 15 9 10

• Specific target organ toxicity - single exposure (respiratory tract irritation) - Category 3 - Respiratory tract irritation9 10

Danger

Flammable Solids : Undefined hazard statement
Substances and Mixtures which, in Contact with Water, Emit Flammable Gases : Undefined hazard statement
Harmful if swallowed (H302)
On contact with water releases gases which are fatal if inhaled
Causes skin irritation (H315)
Causes serious eye damage (H318)
May cause respiratory irritation (H335)

Ingredient disclosure

Comments:

There are no data available for the Phosphorus pentasulfide regarding its irritation or corrosion ability. However, it forms on contact with water a corrosive substance: Phosphoric acid.

Due to the lack of data, classification regarding specific organ toxicity - repeated exposure (H372) was established by analogy to Phosphorus compounds.

This product belongs to the hazard class "Combustible dust" if 5% or more by weight of its composition has a particle size < 500 µm.
