1\. Assessment Scope
This risk assessment covers all activities related to confined space entry, including but not limited to: pre-entry checks, atmospheric testing, entry and exit procedures, work performed inside the confined space, and emergency rescue operations. It applies to all personnel who may be required to enter, work in, or supervise work in confined spaces. Excluded from this assessment are spaces not meeting the definition of a confined space as per regulatory guidelines.
2\. Risk Assessment Methodology
This risk assessment employs a 5x5 risk matrix to determine risk ratings based on likelihood and severity. The hierarchy of controls (Elimination, Substitution, Engineering, Administrative, and PPE) is followed to identify and implement control measures.

What is an Entry Permit System? What should happen when work is being done in a confined space? What are some emergency response precautions? How many people must be present while work is being done in a confined space? Is worker training important? ## What is a Confined Space Hazard Assessment and Control Program? To manage the risks associated with working in confined spaces, employers must develop and implement a confined space hazard assessment and control program. A confined space hazard assessment and control program, specific to the work being conducted, should be written for work in each and every confined space. A confined space hazard assessment and control program should include the following: - Description of roles and responsibilities of each person or party (e.g., employer, supervisor, workers, attendants, and emergency response team). - Advice on how to identify confined spaces. - The identification and assessment of all potential hazards that may exist at the beginning of the work as well as those that may develop because of the work activities. - A procedure to conduct atmospheric testing and monitoring, as required. - A plan to eliminate or control all identified hazards. - Written work procedures. - Training program for all the workers that will enter into the confined spaces. - The establishment of an entry permit system for each entry into a confined space.

# Why is working in a confined space more hazardous than working in other workspaces? (cont.) ## What should be done when preparing to enter the confined space? (cont.) The results of the tests for these hazards are to be recorded on the Entry Permit along with the equipment or method(s) that were used in performing the tests. Air testing is often ongoing, depending on the nature of the potential hazards and the nature of the work. Conditions can change while workers are inside the confined space and sometimes a hazardous atmosphere is created by the work activities in the confined space. For more information see our OSH Answers document on Confined Space - Atmospheric Testing. ## How are hazards controlled in confined spaces? Hazards and risks associated with a confined space must first be identified through a risk assessment. After this is done, a hazard control program can be put in place. The traditional hazard control methods found in regular worksites, which are implemented based on the hierarchy of controls, can be effective in a confined space. The most effective controls are elimination and substitution, if these are not possible or if there is remaining risk, then engineering controls should be considered. Administrative controls should also be put in place to complement other controls. The last measure to consider is personal protective equipment. However, often because of the nature of the confined space and depending on the hazard, special precautions not normally required in a regular worksite may also need to be taken. Elimination removes the hazard (e.g., finding another way to complete a job without entering a confined space) and substitution replaces a hazard with a safer one (e.g., using cold work methods instead of hot work). An engineering control commonly used in confined spaces is mechanical ventilation. The entry permit system is an example of an administrative control used in confined spaces. Personal protective equipment (such as res…

# Confined Space - Program (cont.) ## What should happen when work is being done in a confined space? (cont.) - Understands the nature of the hazards that may be found inside that particular confined space and can recognize signs, symptoms and behavioural effects that workers in the confined space could experience. - Monitors the confined space and surrounding area and is on the look out for dangerous conditions. - Remains outside the confined space and does no other work which may interfere with their primary duty of monitoring the workers inside the confined space. - Maintains constant two-way communication with the workers in the confined space. - Orders the immediate evacuation if a potential hazard, not already controlled for, is detected. - Calls for emergency assistance immediately if an emergency develops. - Is immediately available to provide non-entry emergency assistance when needed. - Can provide entry rescue only after the most stringent precautions are taken and another attendant is immediately available to assume the attendant duties Should a worker leave a confined space for a short time (for example, coffee break, getting additional material for their work), the confined space should be re-tested before the worker re-enters. If the confined space has been continuously monitored by equipment that can show the details of the atmosphere during the time absent from the confined space and this information can be seen from outside the confined space, it can be re-entered without retesting. If there is no continuous air monitoring then the hazard assessment needs to be repeated. No confined space should be closed off until it has been verified that no person is inside it. After exiting the confined space, the time of exit should be noted on the entry permit. ## What are some emergency response precautions? The detailed plan for emergency response to an injury or other emergency within the confined space should be described in detail in the…

# Confined Space - Program (cont.) ## What is a Confined Space Hazard Assessment and Control Program? (cont.) - Development of an emergency plan complete with training and equipment in case an unforeseen situation occurs. - An emergency response system. - Reporting and investigating incidents related to work in confined spaces. - Record and documentation control. - Program review whenever there is a change in circumstances or at least annually, to identify program weaknesses and make any necessary changes to the program. More information about confined spaces is located in the OSH Answers documents Confined Spaces - Introduction and Confined Space - Atmospheric Testing. ## What is an Entry Permit System? An entry permit is an administrative tool used to document the completion of a hazard and risk assessment for each confined space entry. Someone fully trained and experienced in confined space work should complete the entry permit. Some jurisdictions require a permit for all confined space entries. An entry permit is required for confined spaces where the hazard and risk assessment determined that the measures to control the risk involve the following: - atmospheric monitoring, - isolation, - lockout, - ventilation, - safeguarding devices, - respiratory protection, or - any other control that needs to be verified and documented in the permit as required by the assessment. Before entering a confined space, an entry permit should be completed. It should contain at least the following information: - The length of time the permit is valid for. - The name(s) of the worker(s) that are authorized to enter the confined space. - The name(s) of the attendant(s) (safety watch). - The name of the supervisor responsible for the work. - The location and description of the confined space.
