How long does a HMIRA Registration last?

A HMIRA registry number expires after 3 years. If the formula changes or new information changes the SDS classification, a new registration must be applied for.

What is a Generic Chemical Identity?

Terms such as “trade secret”, “proprietary”, “confidential” “surfactant”, “solvent” are not permitted in place of a chemical identity on a Safety Data Sheet.

The Safety Data Sheet must use a Generic Chemical Identity (CGI). The objective is to mask part or all of the chemical name while at the same time retain identity of the general class or structure so that it can still be connected to hazard information disclosed on the Safety Data Sheet.

For example “2,2,3,3,4,4,5,5,6,6,6-undecafluoro-N,N-bis(2-hydroxyethyl) hexanamide” could be written as “Polyhalo-N-bis(hydroxylalkyl) alkanamide”

How does the Workplace Hazardous Materials Bureau review the application?

The WHMB reviews the application to ensure it meets 2 criteria:

1) Does the claim meet Sec. 3(1) of the Hazardous Materials Information review Regualtions (HMIRR)?

  • Is the information confidential to the claimant?
  • Has the claimant taken measures that are reasonable in the circumstances to maintain the confidentiality of the information; and
  • Does the information have actual or potential economic value to the claimant or to the claimant’s competitor, and will disclosure of the information result in a material financial loss to the claimant or a material financial gain to the competitor?

2) Review of the formula and Safety Data Sheet in its entirety.

  • Ingredients are researched in the literature, and a toxicologist constructs a hazard profile.
  • Screening Officer reviews the SDS in context of that research to confirm its compliance with the Hazardous Products Regulations.
  • Issues a Statement of Decision (SOD) whether it is a valid claim as per HMIRR 3(1) and whether SDS is compliant.
  • If the SDS is not compliant, SOD details require edits.
