What Manitoba requires
- Every employer ensures regular inspections of the workplace and of work processes and procedures to identify any risk to the safety or health of any person, and corrects any unsafe condition as soon as is reasonably practicableWorkplace Safety and Health Regulation, M.R. 217/2006, s. 2.4 (1)
- Fall protection applies wherever a worker may fall 3 m or more, less than 3 m where the surface or item below increases the risk of injury, into operating machinery, into water or another liquid, into or onto a hazardous substance or object, through an opening in a work surface, or more than 1.2 m from an area used as a wheelbarrow path; a guardrail system is used, and where that is not reasonably practicable or effective, a travel restraint system, fall arrest system, safety net or another approved systemWorkplace Safety and Health Regulation, ss. 14.1 (1), 14.3, 14.6
- The employer develops and implements safe work procedures to prevent falls, trains workers in them and makes sure they are followed; they identify the fall hazards and the prevention measures and, where guardrails or fall protection systems are needed, their locations, how the systems are assembled, maintained, inspected, used and taken down, and the rescue procedure after an arrested fall; when a guardrail is removed for work, workers in the area use a fall protection systemWorkplace Safety and Health Regulation, ss. 14.2, 14.5
- An employer who proposes an excavation more than 1.5 m deep that a worker will enter notifies the Workplace Safety and Health branch before the day the work is scheduled to begin (the regulation says not more than 48 hours before that day), giving the landowner, employer, location, dates, dimensions, the proposed support structure, confirmation that underground facility owners were notified, and the supervisor's nameWorkplace Safety and Health Regulation, s. 26.4 (1)
- Work at an excavation is supervised by the employer or a designated competent person who is present whenever a worker is in the excavation or work on it is under way; when a worker is in an excavation more than 1.5 m deep, a competent person is at the surface to warn of unsafe conditions and help in an emergencyWorkplace Safety and Health Regulation, s. 26.5
- Before excavation work begins, the employer notifies the owners of underground facilities in the area, makes sure the owners have conspicuously marked their locations, and obtains the owners' information and instructions on precautionsWorkplace Safety and Health Regulation, s. 26.6 (1)
- A worker may enter an open excavation more than 1.5 m but not more than 3 m deep only if its walls are sloped at no more than 45 degrees from horizontal, benched with a vertical face of no more than one metre, shored to the regulation's schedule, held by another support structure, or stabilized as a professional engineer designed and certified (solid rock excepted); deeper than 3 m, a professional engineer designs and certifies the support; at 1.5 m or less, support is installed where there is a danger of cave-inWorkplace Safety and Health Regulation, s. 26.15 (1) to (4)
- Excavated material is placed at least one metre from the edge and piled so it cannot fall in; where a worker enters an open excavation or trench more than 1.5 m deep, a ladder, stairway or ramp is provided, and a ladder in a trench is no more than 3 m from the workerWorkplace Safety and Health Regulation, ss. 26.10 (2), 26.14 (2), (3)
- Where a safety and health committee is required, its duties include the inspection of the workplace at regular intervalsThe Workplace Safety and Health Act, C.C.S.M. c. W210, s. 40 (10) (h)
Regular inspections
Employers make sure the workplace, and the way work is done there, is inspected regularly for risks to anyone's safety or health, and unsafe conditions are corrected as soon as reasonably practicable. Where a safety and health committee is required, inspecting the workplace at regular intervals is one of its duties.
Fall protection
Fall protection applies where a worker could fall 3 m or more, less where the landing makes injury more likely, into machinery, water or hazardous substances, through an opening, or more than 1.2 m from a wheelbarrow path. A guardrail comes first; otherwise travel restraint, fall arrest or a safety net.
The employer writes safe work procedures for falls that name the hazards, where guardrails and fall protection systems go, how they are set up, inspected and taken down, and how a fallen worker is rescued, and trains workers in them. When a guardrail is taken down for work, workers nearby use fall protection.
Excavations
Before an excavation over 1.5 m deep that workers will enter, the employer notifies the Workplace Safety and Health branch with the details, including the support structure and the supervisor. Underground facility owners are notified and mark their lines before digging starts.
A competent supervisor is present while anyone is in the excavation, and another competent person stays at the surface when it is over 1.5 m deep. From 1.5 m to 3 m the walls are sloped, benched, shored or otherwise supported; deeper than 3 m an engineer designs the support. Spoil stays at least one metre back, and a ladder in a trench is within 3 m of the worker.
Common mistakes
- Opening an excavation over 1.5 m that workers enter without notifying the branch.
- No one at the surface while a worker is in a deep trench.
- Spoil piled right at the edge instead of at least one metre back.
- Taking down a guardrail without putting workers on fall protection.
- No written rescue procedure for workers on fall arrest.
