Part 36 Mining

Section 573 Approval

Subsection 573(1)

The OHS Code is intended to prevent the introduction of sub-standard vehicles into mines. All new rubber-tired, self-propelled equipment that meets the size criteria must meet the requirements of the OHS Code and a representative unit must be accepted by the Director before being put to use.

With the exception of section 574, the requirements of sections 573 to 596 are directed at large-sized mobile equipment that is self-powered and rubber-tired. Considering the gradient and condition of mine roads, the safety equipment provided on these vehicles has always been the focus of special attention. Although there have been few recent incidents in Alberta, statistics on brake failures, loss of steering, instability and road handling have not always been favourable. As the performance of safety components has improved over time, truck load factors and vehicle speeds have increased. As a result, the OHS Code requires correspondingly greater attention to these safety requirements.

Subsection 573(2)

The OHS Code does not apply to vehicles having a GVW of less than 32,000 kilograms unless specifically noted or specifically designated by the Director. This subsection provides the Director with the authority to request that any size or type of rubber-tired, self-propelled machine be tested and approved before being put into use. Such a request would be made after reported safety incidents, or upon the recommendation of the Director’s mechanical engineering consultant.

Subsection 573(2)(c) provides an exemption for testing for any machine that has already been approved for use on Alberta’s highways by being approved under the Traffic Safety Act.

Subsection 573(3)

Instead of complying with the manufacturer’s specifications requirements of section 12 of the OHS Code, rubber-tired, self-propelled machines that exceed their manufacturer-specified load weights can be operated if

(a) a written hazard assessment meeting the requirements of Part 2 has been completed, and
(b) controls that ensure safe operation of the rubber-tired, self-propelled machine have been implemented.

The assessment and controls do not need to be reviewed by the Director prior to being implemented. If an officer inspects a work site and considers the assessment or controls insufficient, then the assessment and controls may need to be reviewed by the Director.
