What you'll learn

Describe the hazards of demolition and renovation, the requirements of Part 33 and Part 37 of Manitoba's Workplace Safety and Health Regulation and CSA S350, and how the owner, consultants, contractors and prime contractor share control.
Plan and use an engineering survey of a structure and its neighbours, including load paths, condition, alterations and special elements, and turn it into a demolition plan with hold points.
Explain how a hazardous materials survey is done, what it must look for, how its results become an abatement specification, and how clearance releases an area for demolition.
Describe the health effects of asbestos, the classification of asbestos work by risk, and the controls used for friable and non-friable removal, decontamination and waste.
Identify lead, PCBs, mercury, refrigerants, fuel tanks and contaminated soil in older buildings and apply the controls for each, including avoiding torch cutting of lead-painted steel.
Control respirable crystalline silica, mould and dust in demolition and renovation, including water, local exhaust, enclosed cabs, containment and negative pressure.
Locate, disconnect, confirm and record services before demolition, provide separate temporary services, and isolate circuits, pipes and fire protection safely in renovation.
Apply the principles of structural stability during demolition: top-down sequence, loads before supports, wall stability, floor loads, direction of fall and prestressed elements.
Set up and work around demolition machines and cranes safely, including guarding, stable platforms, attachments, exclusion zones and crane limits.
Plan interior strip-out in an occupied building, keeping exits, fire separations and fire protection working and separating the work from occupants.
Move debris safely through chutes and floor openings and protect workers from falls and falling debris as demolition opens edges and holes.
Protect the public and neighbours from falling debris, traffic, dust, noise and vibration, and plan and practise emergency response for demolition.
