Published by SALUSWhen dealing with confined spaces, it is crucial to follow specific safety protocols to ensure the safety of workers. Here are some key points based on the provided documents:
- Authorization and Record Keeping: Confined spaces must not be entered without the employer's authorization. Employers are required to keep an up-to-date record of all confined spaces, which should be accessible to employees before entry [1].
- Hazard Assessment: Employers must appoint qualified individuals to assess the hazards associated with confined spaces. This includes specifying necessary tests to determine potential exposure to hazards and recording the findings in a signed and dated report [1].
- Code of Practice: A written code of practice must be established, governing the procedures for entering and working in confined spaces. This code should be maintained, periodically reviewed, and must identify all potential confined space work locations [2].
- Training: Workers involved in confined space entry must be trained by a competent person to recognize hazards and perform their duties safely. Training records should be maintained by the employer [2].
- Ventilation and Atmospheric Testing: If a hazardous atmosphere is identified, the confined space must be ventilated or purged before entry. Continuous monitoring may be required to maintain a safe atmosphere, and workers should be trained in evacuation procedures in case of ventilation failure [3].
- Emergency Response: Employers must ensure that effective rescue operations can be carried out if needed. This includes developing and implementing emergency procedures and ensuring that rescue equipment is readily available [3].
- Entry and Exit Procedures: Safe entry and exit procedures must be established, taking into account the specific conditions of each confined space. This includes ensuring that openings are sufficient for safe passage while using protective equipment [1].
By adhering to these guidelines, employers can significantly reduce the risks associated with working in confined spaces and ensure a safer working environment for their employees.

## Ventilation and purging - 53 (1) If the atmospheric testing under section 52 identifies that a hazardous atmosphere exists or is likely to exist in a confined space, an employer must ensure that the confined space is ventilated, purged or both before a worker enters the confined space. - 53 (2) If ventilating or purging a confined space is impractical or ineffective in eliminating a hazardous atmosphere, the employer must ensure that a worker who enters the confined space uses personal protective equipment appropriate for the conditions within the confined space. - 53 (3) If mechanical ventilation is needed to maintain a safe atmosphere in a confined space during the work process, an employer must ensure it is provided and operated as needed. - 53 (4) If mechanical ventilation is required to maintain a safe atmosphere in the confined space, the employer must ensure that - (a) the ventilation system incorporates a method of alerting workers to a failure of the system so that workers have sufficient time to safely leave the confined space, and - (b) all workers within the confined space have received training in the evacuation procedures to be used in the event of a ventilation system failure. - 53 (5) All workers must evacuate a confined space or use an alternative means of protection if a ventilation system fails. ## Inerting 54 (1) An employer must ensure that a confined space is inerted if it is not reasonably practicable to eliminate an explosive or flammable atmosphere within the confined space through another means. - 54 (2) If a confined space is inerted, an employer must ensure that - (a) every worker entering the confined space is equipped with supplied air respiratory protective equipment that complies with Part 18, - (b) all ignition sources are controlled, and - (c) the atmosphere within the confined space stays inerted while workers are inside. ## Emergency response - 55 (1) An employer must ensure that a worker does not enter or remain in a con…

## Part 5 Confined Spaces ## Code of practice 44 (1) An employer must have a written code of practice governing the practices and procedures to be followed when workers enter and work in a confined space. - 44 (2) The code of practice must - (a) take into account and apply the requirements of this Part and of section 169, - (b) be maintained and periodically reviewed, and - (c) identify all existing and potential confined space work locations at a work site. - 44 (3) A worker involved in any aspect of a confined space entry must comply with the requirements and procedures in the code of practice. ## Hazard assessment - 45 If a worker will enter a confined space or a restricted space to work, an employer must appoint a competent person to - (a) identify and assess the hazards the worker is likely to be exposed to while in the confined space or restricted space, - (b) specify the type and frequency of inspections and tests necessary to determine the likelihood of worker exposure to any of the identified hazards, - (c) perform the inspections and tests specified, - (d) specify the safety and personal protective equipment required to perform the work, and - (e) identify the personal protective equipment and emergency equipment to be used by a worker who undertakes rescue operations in the event of an accident or other emergency. ## Training - 46 (1) An employer must ensure that a worker assigned duties related to confined space or restricted space entry is trained by a competent person in - (a) recognizing hazards associated with working in confined spaces or restricted spaces, and - (b) performing the worker's duties in a safe and healthy manner. - 46 (2) An employer must keep records of the training given under subsection (1). - 46 (3) An employer must ensure that competence in the following is represented in the workers responding to a confined space or restricted space emergency: - (a) first aid; - (b) the use of appropriate emergency response equipment; - (c…

The employer may either keep the record in the work place or keep a centralized record of confined spaces in respect of several work places in one work place. - (5) If it is likely that an employee will enter a confined space that has been determined not to be a hazardous confined space in order to perform work for the employer, the employer must establish procedures with respect to safe entry and exit as well as person-check and emergency response systems to ensure the continued safety of employees. SOR/2021-143, s. 1. ## Hazard Assessment - 11.03 (1) If it is likely that a person will enter a hazardous confined space in order to perform work for an employer, the employer must appoint one or more qualified persons to - (a) carry out an assessment of the hazards to which the person is likely to be exposed in that hazardous confined space or in a hazardous confined space of the class to which it belongs; and - (b) specify the tests that are necessary to determine whether the person is likely to be exposed to any of the hazards identified under paragraph (a). - (2) The employer must ensure that the qualified person or persons record the findings of the assessment in a signed and dated report to the employer that specifies the following: - (a) the protection equipment referred to in part XII that is to be used by every person granted access to the hazardous confined space by the employer; - (b) any insulated protection equipment and tools referred to in Part VIII that a person may n…
