What information needs to be disclosed on a WHMIS MSDS?

                                                                                         

In Canada all WHMIS controlled products must have an associated MSDS. The Controlled Products Regulations (CPR) sets out what type of information must be disclosed on these MSDSs. The legislation states there must be at least nine categories of information in regards to the chemical product. The headings of the MSDS categories must be as similar as possible to the suggested headings set out by the CPR. Within these headings the information released is preferred to be the same as requested by the CPR. It can differ slightly but must at least be related to the heading topic. Any information stated under one heading within the MSDS does not have to restated in another section.
The nine headings, and their associated information, as stated by the Controlled Products Regulations, are as follows:

1.Hazardous Ingredients
-Information required by subparagraphs 13(a)(I) to (iv) of the Hazardous Products Act (HPA)
-CAS number and product identification number
-LD50 of each component (including species and route used for testing)

2.Preparation Information
-Name and phone of the person responsible for preparing the MSDS
-Date of MSDS preparation

3.Production Information
-Manufacturer's name, street address, city, province, postal code and emergency
telephone number
-Supplier identifier, the supplier's street address, city, province, postal code and emergency telephone number
-Product identifier
-Product use

4.Physical Data
-Physical state (i.e. gas, liquid or solid) -Odour and appearance
-Odour threshold -Specific gravity
-Vapour pressure -Vapour density
-Evaporation rate -Boiling point
-Freezing point -pH
-Coefficient of water/oil distribution

5.Fire or Explosion Hazard
-Conditions of flammability
-Means of fire extinction
-Flash point and method of determination
-Lower and upper flammability limits
-Auto-ignition temperature
-Hazardous combustion products
-Explosion data; sensitivity to mechanical impact, sensitivity to static discharge

6.Reactivity Data
-Conditions under which the product is chemically unstable
-Substance or class of substance which are incompatible with the product
-Conditions of reactivity
-Hazardous decomposition products

7.Toxicological Properties
-Route of entry skin contact, skin absorption, eye contact, inhalation and ingestion
-Effects of acute and chronic exposure to product
-Exposure limits
-Irritancy of product
-Sensitization to product
-Carcinogenicity
-Reproductive toxicity
-Teratogenicity
-Mutagenicity
-Name of toxicologically synergistic products

8.Preventive Measures
-Personal protective equipment
-Specific engineering controls
-Procedures to be followed in case of leak or spill
-Waste disposal
-Handling procedure and equipment
-Storage requirements
