Demolition and renovation DSS guide
Built around the City of Windsor's demolition permit checklist, which asks for a designated substance list. The second half covers what to do when suspect material turns up mid-job.
- The owner lists every designated substance before the project beginsOHSA section 30 puts this on the project owner, and the list goes into the tender.
- The list covers all 11 substances in the work areaNot just asbestos: lead, mercury, silica and the rest are part of the same list.
- Demolition permits need itThe City of Windsor's demolition permit checklist asks for the designated substance list with the application.
- Abatement follows the surveyA specification sets the procedure type, quantities and scope before abatement is bid.
- Type 3 work needs clearance before the enclosure comes downAggressive air testing below 0.01 fibres per cc, done by someone independent of the abatement contractor.
- Mid-job find: stop work except to identify the materialDon't keep cutting or demolishing in that area.
- Mid-job find: notify right awayThe constructor or employer notifies the Ministry, the owner, the contractor and the JHSC.
- Mid-job find: test or presumeWait for results, about a week, or treat the material as asbestos-containing and follow the matching procedures.
