1Under Section 17 of the Technical Standards and Safety Act, 2000, which of the following powers is granted to an inspector conducting an inspection of a regulated facility?

A.To modify the adopted ASME safety codes without consulting the director.

B.To permanently revoke a mechanic's certificate of qualification on the spot.

C.To issue financial fines directly to a building owner without a court order.

D.To enter any premises at any reasonable time without a warrant to perform inspections.

Explanation: Section 17 of the Technical Standards and Safety Act, 2000, authorizes an inspector to enter and inspect any premises at any reasonable time where regulated things are used, operated, installed, or maintained, for the purpose of ensuring compliance with the Act and regulations. Inspectors cannot permanently revoke certificates, change code documents, or issue direct fines without following administrative procedures.

2According to Ontario Regulation 209/01 (Elevating Devices), when an accident occurs that results in death or serious injury, how must the incident be reported to the TSSA?

A.During the next scheduled annual inspection.

B.By written notice within 7 days.

C.Immediately by telephone.

D.By written notice within 24 hours.

Explanation: Ontario Regulation 209/01, Section 36, requires that where an accident occurs that results in death or serious injury, the owner or licensee must notify the director immediately by telephone. A written report must follow within 24 hours of the incident.

3Under O. Reg. 209/01, if a mechanic performs a major alteration on an elevating device, when must the device be inspected and returned to service?

A.The device can be returned to service immediately, provided a TSSA inspection is scheduled within 30 days.

B.The device must be kept out of service for a mandatory 14-day observation period before public use.

C.The device can be returned to service as long as a registered contractor signs off, with no TSSA notification required.

D.The device must be inspected by a TSSA inspector and registered before it is returned to service.

Explanation: Ontario Regulation 209/01 requires that after a major alteration, the elevating device must not be returned to service until it has been inspected by a TSSA inspector and the registration has been updated. This ensures the safety and compliance of the structural or mechanical changes.

4What is the restriction on an Elevating Device Mechanic-In-Training (EDM-T) certificate holder performing tasks on elevating devices?

A.They can work unsupervised on hydraulic elevators but require supervision on traction elevators.

B.They can perform routine maintenance unsupervised but require supervision for alterations.

C.They must always work under the direct supervision of a mechanic holding the appropriate class of certificate.

D.They can work unsupervised after completing their first 2,000 hours of apprenticeship.

Explanation: An EDM-T is a mechanic-in-training and, under Ontario regulations, must work under the direct supervision of a certified mechanic of the appropriate class (e.g., EDM-A). They are not permitted to perform any work unsupervised at any point in their training.

5Where must the maintenance logbook for an elevating device be kept according to O. Reg. 209/01?

A.At the main office of the registered elevator contractor.

B.With the building manager at the front desk of the facility.

C.In a secure, locked box located at the main electrical entrance of the building.

D.In the machine room, machine space, control room, or control space of the device.

Explanation: Regulations require the maintenance logbook to be kept in the machine room, machine space, control room, control space, or on the device itself. This ensures it is immediately accessible to any mechanic or inspector performing work on that specific elevating device.

6Under O. Reg. 209/01, for what minimum duration must the maintenance logs and records for an elevating device be retained at the installation?

A.1 year

B.10 years

C.2 years

D.5 years

Explanation: Ontario Regulation 209/01 and the Code Adoption Document (CAD) specify that maintenance logbooks and records must be retained at the installation for at least 5 years. These records are critical for tracing the safety history and maintenance intervals of the device.

7In Ontario, what is the primary code governing the design, construction, and installation of elevators and escalators as referenced by the TSSA CAD?

A.Ontario Building Code (OBC) Part 3

B.CSA B355 Safety Code for Lifts for Persons with Physical Disabilities

C.ASME A17.1 / CSA B44 Safety Code for Elevators and Escalators

D.Canadian Electrical Code (CSA C22.1) Section 38

Explanation: The primary safety standard adopted under the TSSA Code Adoption Document (CAD) for new and existing elevators and escalators is the ASME A17.1 / CSA B44 Safety Code. Other codes like CSA B355 apply to handicap lifts, and C22.1 governs electrical systems, but B44 is the main elevating code.

8Under O. Reg. 209/01, who is legally responsible for ensuring that an elevating device has a valid licence and is registered with the TSSA?

A.The maintenance contractor's field mechanic

B.The manufacturer of the elevator

C.The owner of the elevating device

D.The TSSA regional inspector

Explanation: The owner of the elevating device is legally responsible for maintaining the device's license, registering it, and ensuring it is operated in accordance with the TSSA Act and Regulations. Mechanics must ensure they work safely and follow codes, but the licensing responsibility lies with the owner.

9If an inspector seals an elevating device out of service due to an unsafe condition, what must happen before the seal can be legally broken?

A.An inspector must remove the seal, or authorize a mechanic to do so after repairs are completed.

B.The field mechanic can cut the seal immediately upon arriving to perform diagnostic testing.

C.The building manager can remove the seal once the contractor promises to attend the site.

D.The seal automatically becomes invalid 48 hours after being placed if no follow-up is received.

Explanation: Under the TSSA Act, only an inspector or a certified mechanic authorized by an inspector may remove or break a seal. The device must be repaired, and permission must be granted before the device is returned to service.

10What is the maximum penalty for an individual convicted of an offence under the Technical Standards and Safety Act, 2000?

A.A fine of up to $10,000 and 30 days in jail.

B.A fine of up to $1,000,000 and permanent revocation of all trade licenses.

C.A fine of up to $50,000, imprisonment for up to 12 months, or both.

D.A fine of up to $5,000 and mandatory retaking of the EDM exam.

Explanation: Section 37 of the TSSA Act states that any individual who is convicted of an offence is liable to a fine of not more than $50,000 or to imprisonment for a term of not more than one year, or to both. Corporations face much higher fines (up to $1,000,000).
