Confined space safety is a critical concern in industries like construction, manufacturing, and oil & gas, where workers regularly enter potentially hazardous environments.
In Canada, an average of 20 workers die each year due to confined space accidents, emphasizing the importance of strict safety protocols.
A confined space safety audit plays a key role in evaluating and improving safety standards, ensuring compliance with regulations such as those set by the Canadian Centre for Occupational Health and Safety (CCOHS) and provincial Occupational Health and Safety (OHS) codes.
This audit assesses the safety of confined spaces, identifies potential risks, and ensures that appropriate safety measures are in place, such as proper ventilation, rescue procedures, and worker training.
Preparing for such an audit is crucial for both regulatory compliance and protecting your workforce.
In this article, we will guide you through the necessary steps to prepare for a confined space safety audit.
From reviewing safety documentation and equipment to ensuring that employees are trained and safety protocols are up to date, we’ll cover everything you need to ensure your audit goes smoothly and that your workplace remains safe for everyone involved.
What is Confined Space and Regulatory Standards
A confined space is defined as a location that is large enough and configured to allow an employee to enter and perform certain tasks but has limited or restricted means of entry or exit.
These spaces are not intended for continuous occupancy, and in many cases, they can present hazards that may not be immediately visible or recognized. Examples include tanks, silos, sewers, storage bins, ducts, and vaults.
Regulatory Standards for Confined Spaces
To protect workers from the dangers associated with confined spaces, regulatory bodies like the Occupational Safety and Health Administration (OSHA) have established clear standards for working in such environments.
OSHA’s regulation for confined spaces is found under 29 CFR 1910.146, which outlines the criteria for recognizing confined spaces and implementing proper safety measures.
The regulation is designed to safeguard employees who may be exposed to potentially hazardous conditions, such as toxic air, poor ventilation, or risk of engulfment.
Employers must follow these standards to ensure that workers have the necessary protections in place, such as proper ventilation, personal protective equipment (PPE), and rescue plans.
Additionally, confined spaces should only be entered by trained personnel who have been provided with the right safety equipment and procedures.
The Importance of Compliance
Adhering to confined space safety standards is not only a legal requirement but also an essential aspect of protecting workers' health and safety.
Non-compliance can lead to serious accidents, including injuries or fatalities, as well as significant financial penalties.
In Canada, compliance with similar regulations like those outlined by Workplace Safety and Insurance Board (WSIB) or CSA Z1006-16 (for confined space operations) is equally crucial.
Ensuring proper training, monitoring, and audits can prevent accidents, improve safety performance, and reduce the risk of liability for businesses.
Understanding and applying these regulatory standards can help create a safer work environment, particularly for those employees working in or around confined spaces.
What to Prepare Before the Confined Space Safety Audit

Equipment and PPE Checks
One of the most critical aspects of a confined space safety audit is ensuring that all required equipment and personal protective equipment (PPE) are in good working condition and available when needed.
During the audit, inspectors will focus on several key items that are vital to the safety of personnel who work in confined spaces.
Proper equipment checks, regular calibration, and keeping detailed inspection logs are essential for ensuring compliance with safety regulations and minimizing risks in confined space operations.
Common Equipment Inspected by Auditors
- Gas Monitors: These devices are crucial for measuring the levels of hazardous gases, such as oxygen, carbon monoxide, hydrogen sulfide, and combustible gases, in a confined space. Auditors will check that gas monitors are functioning properly and that calibration records are up to date. Improperly calibrated or malfunctioning monitors pose a severe risk to workers' safety, as they might fail to detect dangerous gas levels.
- Harnesses and Fall Protection Gear: Confined spaces often have entry points that are elevated or have limited space, requiring workers to use fall protection gear like harnesses, lanyards, and lifelines. Auditors will verify that all harnesses and related gear are in good condition, free of damage, and meet regulatory standards (e.g., CSA Z259). The equipment should also be inspected regularly for wear and tear, and these inspection logs should be available for review.
- Signage and Warning Systems: Proper signage is crucial in indicating confined spaces and warning workers about potential hazards. The audit will focus on ensuring that signs are clear, visible, and compliant with regulatory standards. This includes proper labeling of confined spaces, indicating the specific risks present, and marking emergency exits or rescue points.
Importance of Calibration and Inspection Logs:
Proper calibration and maintenance of equipment are paramount to safety in confined spaces.
For instance, gas monitors should be calibrated before every use to ensure they detect gas concentrations accurately. Likewise, all fall protection equipment, breathing apparatus, and other PPE should be inspected and maintained regularly.
How to prepare
- Ensure all equipment, including gas monitors, harnesses, and fall protection gear, is inspected regularly and maintained according to manufacturer guidelines.

Training and Competency Requirements
Another important focus during a confined space safety audit is ensuring that the workers involved in confined space activities have the appropriate training and competencies.
Proper training is not only a regulatory requirement but also ensures that all personnel understand the hazards, protocols, and emergency procedures associated with confined space work.
The audit will review who has received training, what competencies are required, and whether refresher courses and drills are regularly conducted.
Who Needs to Be Trained
- Entrants: These are the workers who actually enter confined spaces to perform tasks. Entrants must be trained in the specific hazards they may face, including atmospheric risks (e.g., oxygen deficiency or toxic gases), physical hazards (e.g., moving machinery or falling objects), and the appropriate use of PPE. They should also understand emergency evacuation procedures.
- Attendants: An attendant is responsible for monitoring the safety of the entrants from outside the confined space. They must be trained to recognize potential hazards and know how to act in case of an emergency, such as initiating rescue procedures or contacting emergency services.
- Supervisors: Supervisors oversee the confined space entry process, ensuring that all safety procedures are followed and that the correct equipment and training are in place. Supervisors need to have a thorough understanding of all the hazards involved and should be capable of making decisions about when to stop work if safety concerns arise.
Records That Should Be Available
- For the audit, you must have thorough records of the training programs completed by all entrants, attendants, and supervisors. This includes:
- Certification records for each person who has received confined space training.
- Documentation showing the completion of initial training as well as any required refresher training.

- Prepare to show any additional training or competency tests that have been completed, such as rescue training or working with new types of confined spaces.
Refresher Training and Drills
- In addition to initial training, it's essential to conduct regular refresher courses and drills to keep employees up-to-date on confined space safety procedures.
- Drills simulate real-life scenarios, such as evacuating a confined space or rescuing an entrant, and ensure that workers are prepared to respond quickly and effectively in case of an emergency.
How to prepare
- Ensure you conduct regular confined space rescue drills and make sure everyone knows their roles.
- Document all refresher training and drills to show your ongoing commitment to safety.
- Keep a schedule for when future refresher training is due, and make sure to plan these in advance.
By ensuring that the correct training is provided, records are maintained, and regular refresher courses and drills are scheduled, your team will be fully prepared for the confined space safety audit and demonstrate a commitment to workplace safety.
Using a Confined Space Audit Checklist
Preparing for a confined space safety audit can feel overwhelming, especially with so many moving parts—from equipment inspections to verifying training records. That’s where a confined space audit checklist becomes incredibly valuable.
This simple yet powerful tool helps employers and safety teams stay calm, spot gaps, and prepare effectively for an upcoming audit.
A checklist acts like a self-audit, allowing you to walk through all critical safety components and confirm that each requirement is being met. It not only reduces the risk of missing key details but also boosts your confidence when it’s time for a formal inspection.
Why Use a Checklist Before the Audit?
1. Identify Issues Early
A checklist gives you a chance to find and fix problems before an external auditor arrives. Whether it’s expired gas monitor calibration or outdated training certificates, early detection helps prevent audit failures.
2. Standardize the Process
Using a checklist ensures consistency across teams or departments. Everyone follows the same steps, reducing confusion and ensuring a thorough review.
3. Save Time During the Audit
Having everything prepared and documented means the audit can proceed faster and more smoothly. You’ll avoid scrambling to find documents or track down equipment history during the inspection.
4. Promote a Culture of Safety
Regularly using a checklist—even outside of audit season—shows a commitment to safety and accountability. It can also help meet internal corporate standards, insurance requirements, and due diligence obligations.
What Should Be on the Checklist?
A good confined space audit checklist should include:
- Confined space inventory list and classifications
- Entry permits and procedures
- Gas detection equipment inspection/calibration records
- PPE availability and maintenance logs

Common Findings and How to Avoid Them
During a confined space safety audit, certain issues come up more frequently than others—and they’re often preventable.
Whether you’re in construction, manufacturing, or utilities, being aware of these common audit findings can help you stay a step ahead and ensure compliance with both internal policies and legal standards.
Common Findings During Confined Space Audits
1. Missing or Inadequate Signage
One of the most frequent issues is the absence of proper warning signs and labels around confined space entries.
According to Canadian Centre for Occupational Health and Safety (CCOHS) guidelines, clear signage is required to indicate that an area is a confined space and may pose hazards. Without visible warnings, workers may unknowingly enter dangerous areas.
2. Incomplete or Outdated Documentation
Auditors often flag missing entry permits, outdated confined space programs, or poorly kept inspection logs. If your entry permits aren’t signed, dated, or don’t list required monitoring data, it’s a red flag.
Similarly, if your written program hasn’t been reviewed or updated in years, it may no longer reflect current conditions or regulations.
3. Untrained or Improperly Trained Workers
Another critical issue is the lack of proper training or missing records of employee certification.
Workers—especially entrants, attendants, and supervisors—must have up-to-date confined space training. This includes understanding potential hazards, proper use of PPE, and emergency procedures.
4. Faulty or Uninspected Equipment
From expired gas detector calibration to damaged harnesses, faulty equipment is a major compliance issue.
Auditors will check to see if equipment is functional, inspected regularly, and logged properly. Missing inspection dates or calibration records are easy ways to fail an audit.
How to Avoid These Issues
1. Perform Regular Self-Audits
Using a confined space checklist (see previous section) allows you to catch problems early. Make it part of your routine to walk through the checklist monthly or quarterly, not just before a formal audit.
2. Keep Documents Up to Date and Accessible
Designate someone to manage all confined space-related documents and ensure they’re easily accessible. That includes training certificates, permits, inspection logs, and safety meeting notes.
3. Refresh Signage Frequently
Inspect all confined space areas for clear, weather-resistant signage. Replace any faded, missing, or damaged signs immediately.
4. Schedule Routine Training and Drills
Build a training schedule that includes refresher courses and mock rescue drills and equipment. Make sure training logs are maintained and that certifications are current.
5. Track Equipment Maintenance Closely
Use a digital or paper-based log to track when equipment was last inspected or calibrated. Tag equipment with inspection dates and remove any that’s out of service.
By understanding and addressing these common pitfalls, you’ll not only pass your confined space safety audit—you’ll also build a stronger safety culture in your workplace.
Conclusion
Preparing for a confined space safety audit is more than a compliance exercise—it’s a vital step toward protecting your workers and preventing serious incidents.
From reviewing entry permits and training records to checking the condition of your gas monitors and signage, every detail matters.
Ensuring that your confined space program is documented, current, and tailored to your workplace environment is key.
One of the most effective ways to stay audit-ready is through regular internal checks. These self-audits not only help you catch issues early but also foster a proactive safety culture.
It’s also worth involving your team in the process—when workers understand the “why” behind the rules, compliance becomes a shared responsibility rather than a top-down mandate.
Keep in mind that safety protocols and regulations evolve. What passed inspection last year might fall short today.
That’s why continuous improvement—through refresher training, updated procedures, and scheduled equipment maintenance—plays such a crucial role.
If your team is unsure where to start or needs a confidence boost before an upcoming inspection, consider bringing in a certified safety professional to perform a mock audit or deliver tailored confined space safety training.
