Disclaimer: This resource has been prepared to help the workplace parties understand some of their obligations under the Occupational Health and Safety Act (OHSA) and regulations. It is not legal advice. It is not intended to replace the OHSA or the regulations. For further information please see full disclaimer.

The Regulation classifies work involving asbestos on construction projects, buildings and repair operations as either a Type 1, Type 2 or Type 3 operation. The checklists that follow address many of the requirements for Type 1, Type 2 and Type 3 operations and have been prepared to make it easier to determine if the requirements appropriate to the type of operation are being followed.

Each item in each checklist is followed by a reference to the corresponding section of the Regulation.

Disclaimer:

The following checklists are intended to facilitate compliance with the requirements of the Regulation regarding Type 1, 2 and 3 operations. These checklists do not specify every regulatory requirement related to Type 1, 2 and 3 operations and should not be exclusively relied upon to ensure compliance with regulatory requirements. For the comprehensive requirements, please refer to the Regulation.

Note: Throughout this checklist, the use of the term "Hepa vacuuming" refers to vacuuming with a vacuum equipped with a Hepa filter.
