Confined Spaces for Canada
A confined space is defined as a work area which has sufficient space for a person to fit within and perform work, limited means of entry and exit, and a design that was not intended for continuous worker occupancy. Working in a confined space can present hazardous atmospheres and physical dangers to employees. This course will describe the dangers, best practices, and permit requirements necessary when working in a confined space.

Key Questions
What is a confined space?
A hazardous confined space is defined as a work area which has all of the following characteristics: sufficient space for a person to fit within and perform work, limited means of entry and exit, and a design that was not intended for continuous worker occupancy.
What are examples of confined spaces?
Some spaces are clearly “confined,” such as storage tanks, digesters, reactors, or large process pipes which can be opened for access during a shutdown. Confined spaces may also include common areas such as pipe trenches, pits, or rooms where normal exits may be blocked by construction work.
What are the hazards of working in a confined space?
Working in a confined space can represent a “triple threat” of hazards to employees. First, workers run the risk of exposure to a range of hazardous atmospheres when entering a confined space. Second, the space can present physical dangers due to cramped working space, proximity to moving equipment, poor walking surfaces, and the possibility of engulfment. Finally, the nature of confined spaces makes rescue of someone needing assistance within the space much more difficult.
What types of hazards do confined spaces present?
Hazards associated with confined spaces include hazardous atmospheres, physical hazards, and entrance/exit hazads.
What are the different roles on a confined space entry team?
Every confined space entry requires a designated confined space entry team. This team must include an attendant, an entrant, an entry supervisor, and rescue and emergency services.

Exposure to harmful substances or environments is a leading cause of illness and death in the industrial workplace. Working in a confined space can represent a “triple threat” of hazards to employees. First, workers run the risk of exposure to a range of hazardous atmospheres when entering a confined space. Second, the space can present physical dangers due to cramped working space, proximity to moving equipment, poor walking surfaces, and the possibility of engulfment. Finally, the nature of confined spaces makes rescue of someone needing assistance within the space much more difficult. To be sure that work within a confined space is performed safely, employers must develop a program that help workers recognize and avoid these potentially dangerous conditions. Effective confined space entry programs should begin with the education and training of all entrants, attendants, and support personnel.
