Confined Space Compliance in Canada: Regulations, Roles, and Real-World Controls

Safety is a team sport. Every safe entry relies on four roles, each essential and non-negotiable: 

• The employer 

• The entrant  

• The attendant 

• The entry supervisor 

Let’s look at the responsibilities for each role more closely.

The Employer creates and maintains the confined space program. This means they’re involved in identifying hazards, establishing permits, and ensuring training and rescue readiness. 

The Entrant is the worker or who physically enters the confined space. There may be one or multiple entrants. Entrants are required to be fully trained, equipped, and fit for duty. Throughout the entry, they maintain constant communication and must exit at the first sign of distress or alarm. 

The Attendant is the person who stays outside the confined space and ensures the safety of the entrants. An attendant must never enter the confined space, no matter the circumstances. While the entrant works, the attendant is the one who maintains communication, monitors conditions, records data, and initiates rescue if something goes wrong. This person might also be called a monitor or tending worker. 

The Entry Supervisor oversees the entire process, verifies controls, and halts the entry if conditions shift. 

This structure provides protection. Each role closes a gap the others can’t see, forming a continuous chain of accountability that keeps workers alive.
