1Under Ontario Regulation 209/01 (Elevating Devices), what is the maximum time allowed to report an elevating device incident that results in death or serious injury to the TSSA?

A.Immediately

B.Within 24 hours

C.Within 48 hours

D.Within 7 days

Explanation: Under Section 36 of O. Reg. 209/01, where an incident occurs that results in death or serious injury, the owner or contractor must notify a TSSA inspector immediately. A written report must also follow.

2Which of the following is the first step when performing lockout/tagout (LOTO) on a rack and pinion construction hoist?

A.Notify all affected employees that the hoist is being shut down

B.Turn off the main disconnect switch

C.Apply personal padlocks and tags to the disconnect

D.Test the hoist controls to verify zero energy state

Explanation: Before shutting down the system, you must notify all affected workers who rely on or operate the hoist. This prevents confusion and ensures safety during the shutdown process.

3Under Ontario's Construction Projects Regulation (O. Reg. 213/91), at what height above the floor or ground is a worker required to wear fall protection equipment if not protected by guardrails?

A.1.5 meters

B.2.4 meters

C.3.0 meters

D.3.6 meters

Explanation: O. Reg. 213/91 Section 26.1 requires that a worker be protected by a fall protection system if they are exposed to a fall hazard of 3.0 meters (approx. 10 feet) or more. This is standard across Ontario construction sites.

4What is the primary role of a TSSA Elevating Device Inspector on a construction site?

A.To inspect and approve elevating devices for compliance with safety regulations and codes

B.To perform routine maintenance and repairs on construction hoists

C.To act as a supervisor for the hoist installation crew

D.To issue municipal building permits for construction projects

Explanation: TSSA inspectors are responsible for enforcing the Technical Standards and Safety Act and O. Reg. 209/01 by verifying that elevating devices are installed, maintained, and operated in compliance with applicable safety codes.

5In a standard lockout/tagout procedure, who is authorized to remove a personal safety padlock from a hoist main disconnect?

A.The worker who applied the padlock

B.The hoist operator on the next shift

C.The construction site supervisor

D.Any certified elevating device mechanic

Explanation: To ensure absolute safety, only the individual worker who applied a personal lock and tag is authorized to remove it. This prevents the energy source from being re-energized while that worker is still in a hazardous zone.

6When working on top of a construction hoist car during erection or maintenance, what is the preferred method of fall protection?

A.A full-body harness attached to an approved anchorage point

B.A safety belt around the waist connected to the mast

C.Relying on the car top handrails if they are at least 1.0 meter high

D.A safety net suspended below the working level

Explanation: Erection and maintenance tasks on top of the car expose workers to fall hazards, requiring a full-body harness connected to a design-approved anchorage point. Safety belts are not permitted for fall arrest due to the risk of internal injuries.

7What is the purpose of the 'dead-man' switch or safety controls on a construction hoist?

A.To stop the hoist automatically if the operator releases the control lever

B.To shut off power when the car reaches the top landing

C.To prevent the doors from opening when the car is in motion

D.To bypass limit switches during testing and installation

Explanation: A dead-man control requires continuous manual activation to run. If the operator releases the switch due to panic, injury, or distraction, the circuit is broken and the hoist stops immediately.

8If a construction hoist experiences a major structural failure but no injuries occur, what is the TSSA notification requirement?

A.Notify TSSA within 24 hours

B.Notify TSSA immediately

C.Notify TSSA at the time of the next annual inspection

D.No notification is required since there were no injuries

Explanation: Under Ontario O. Reg. 209/01, structural failures, failures of safety components, or fires involving elevating devices must be reported to the TSSA within 24 hours, even if no injury occurs.

9Which license class is required in Ontario to work unsupervised on a construction hoist as an elevating device mechanic?

A.Class B (EDM-B)

B.Class T (EDM-T)

C.Class D (EDM-D)

D.Class F (EDM-F)

Explanation: The EDM-B license is the Class Specific certificate designed for construction hoist mechanics, permitting unsupervised work on personnel and material hoists.

10When working in the hoistway pit, what is a primary safety hazard that a mechanic must guard against?

A.Falling objects from the hoistway above

B.Lack of natural oxygen inside the open pit

C.High wind velocity in the hoistway

D.Radiation from electrical components

Explanation: Overhead falling objects represent a severe hazard in hoistway pits. Mechanics must wear hard hats and ensure overhead protection (like overhead beams or securing the car above) is in place.

About the TSSA EDM-B Exam Exam

The Elevating Device Mechanic Class B (EDM-B) exam is the final step to obtaining a construction hoist mechanic license in Ontario. It validates that an apprentice has acquired the technical knowledge and safety competence necessary to install, maintain, repair, alter, and service personnel hoists, material hoists, and transport platforms. The exam covers safety standards, CSA Z185 and CSA Z256 codes, rigging principles, drive mechanics, electrical safety circuits, and load testing.

Assessment

The official TSSA EDM-B certification exam is a Class Version (CV) exam, typically approximately 75 multiple-choice and true/false questions administered in a 3-hour proctored open-book session. Permitted references are the CSA Z185 Safety Code for Personnel Hoists, CSA Z256 Safety Code for Material Hoists, TSSA Act, and O. Reg. 209/01.
