Administrative Procedure 405
Part 28 of the Alberta Occupational Health and Safety (OHS) Code establishes requirements for employers and employees to follow if employees work alone.
Confined or Restricted Space:
is an enclosed or partially enclosed space that is not designed or intended for continuous human occupancy—for example, crawlspace, air handling unit, serviced tunnel.
means to work alone at a worksite, with no one else present, or in areas of a building that are isolated from view or hearing distance—for example, rooftop, vehicle, boiler room, separate wing of a large building—and where assistance is not readily available in the event of an emergency.
- Principals, Central Services administrators and contractors shall first consider strategies to eliminate situations where employees work alone. Strategies include establishing administrative procedures that address acceptable hours of work, promote a buddy system, and identify what types of tasks can be safely performed alone.
- Employees and contractors shall not work alone when conducting tasks that present a higher risk of injury unless acceptable controls are in place. Controls include establishing a system of visible or audible contact with a person that can readily provide assistance in the event of an emergency. Higher risk tasks include working with powered equipment, or potentially aggressive students.
- Control strategies may include visiting the worker at specified intervals, scheduling check-ins with other staff and reporting to a designated person on completion of a task.
- Employees and contractors shall not work alone when working at heights above 10 feet or when working inside a confined or restricted space.
- Principals, Central Services administrators and contractors shall:
- identify employees that work alone and conduct a hazard assessment involving employees at the worksite to identify existing or potential hazards arising from the conditions and circumstances of the employee’s work;
- take reasonable and practicable steps to eliminate or control the hazards identified by the hazard assessment;
- ensure the hazard assessment and controls are communicated to employees involved and that further hazard assessments are conducted at intervals of time appropriate to the conditions and circumstances of the work;
- provide access to an effective electronic communication system that includes regular contact with a designated person at intervals appropriate to the nature of the hazard associated with the work, and may consist of radio, landline, cellphone or some other means of electronic communication; and
- establish and communicate to employees a written site or department-specific protocol outlining the safe work procedures or practices in place to protect employees working alone.
- A Working Alone Hazard Assessment Checklist (Form 405-1) and sample working alone protocols are available from the Division OHS Specialist.
