As Canada is divided into federal, provincial and territorial jurisdictions here is the legislation pertaining to lone workers on Prince Edward Island.
Summary of Prince Edward Island Lone Worker Legislation
On Prince Edward Island, the Occupational Health and Safety (OHS) Act and its General Regulations describe the standards for occupational health and safety and the general safety principles for Island workplaces.
Occupational Health and Safety Regulations,
Part 53 53.1 In this Part, “working alone” means a worker working at a workplace who is the only worker of the employer at that workplace, in circumstances where assistance is not readily available to the worker in the event of injury, ill health or emergency.
53.2 (1) Where a worker is working alone, the employer shall develop and implement written procedures to ensure, as far as is reasonably practicable, the health and safety of the worker from risks arising out of, or in connection with, the work assigned.
(2) Written procedures developed under subsection (1) shall include the following information:
(a) the name, address, location and telephone number of the workplace;
(b) the name, address, location and telephone number of the employer; p. 3
(c) the nature of the business conducted at the workplace;
(d) identification of the possible risks to each worker working alone that arise from or in connection with the work assigned;
(e) the steps to be followed to minimize the risks identified in clause (d);
(f) details of the means by which a worker who is working alone can secure, and the employer can provide, assistance in the event of injury or other circumstances that may endanger the health or safety of the worker.
(3) The steps referred to in clause (2)(e) shall
(a) specify the time intervals for checking on the worker;
(b) specify the person responsible for contacting the worker and recording the results of the contact;
(c) outline the process to be followed if the worker cannot be contacted, including provisions for an emergency rescue; and
(d) provide for checking with the worker at the end of the worker’s shift.
53.3 The employer and the worker who is working alone shall comply with the procedures developed under section 53.2.
53.4 The employer shall implement a training program in respect of the procedures established under Section 53.2 for each worker who is working alone and for each supervisor who is responsible for a worker working alone.
53.5 The employer shall ensure that a copy of the procedures established under Section 53.2 is available to an officer on request.
If you are looking into the legalities of lone workers on PEI, I would highly recommend reading ‘The Guide to Working Alone Regulations’ published by the Workers Compensation Board to assist with the interpretation of the working alone regulations of Prince Edward Island.
