An occupational health and safety audit, often called an OHS audit, is a structured review of how effectively a workplace manages health and safety.
For British Columbia employers, an OHS audit helps answer an important question:
Does our safety program actually work in practice, or does it only look complete on paper?
A strong audit looks beyond policies and binders. It examines whether responsibilities are understood, hazards are being identified, workers are properly trained, inspections are happening, incidents are investigated, and corrective actions are being completed.
For employers pursuing Certificate of Recognition certification, audits become even more important. WorkSafeBC explains that COR employers must have their occupational health and safety management system assessed through an approved audit process.
This guide explains what an OHS audit is, what auditors typically review, how it differs from a workplace inspection or COR audit, and how BC employers can prepare.
What Is an OHS Audit?
An OHS audit is a systematic assessment of an organization’s occupational health and safety program or management system.
The purpose is to determine whether the systems intended to protect workers are:
documented
implemented
understood
maintained
effective
This is different from simply checking whether a company owns the correct forms or has a safety manual.
An effective occupational health and safety management system includes multiple interconnected elements. These can include hazard identification and risk management, workplace inspections, incident investigations, program administration, worker participation, training, and documentation.
For employers that aren’t sure whether their current documentation is complete, Greenspine’s free safety program review provides a practical starting point for identifying potential gaps before a more formal audit or certification process.
What Does an OHS Audit Look At?
The exact scope of an audit depends on the organization, industry, audit standard, and reason for conducting it.
However, most OHS audits examine several core areas.
Health and Safety Responsibilities
An auditor may look at whether management, supervisors, workers, contractors, and health and safety representatives understand their responsibilities.
Having responsibilities written in a manual is only part of the equation. Auditors may also look for evidence that those responsibilities are actually being carried out.
This distinction matters because an effective workplace safety program in British Columbia should reflect how the organization operates in practice, not simply what is written in its policies.
Hazard Identification and Risk Assessment
A strong safety program should have a process for identifying hazards, assessing their level of risk, and implementing appropriate controls. This can include physical hazards, chemical hazards, ergonomic risks, equipment hazards, environmental conditions, and hazards associated with specific tasks. Organizations should also be able to demonstrate what happens after a hazard is identified.
Who is responsible for correcting it?
How is the corrective action documented?
How does management verify that the problem was actually resolved?
Those are the kinds of questions an OHS audit can uncover.
Safe Work Practices and Procedures
Auditors may review whether the organization has documented procedures for work activities that expose employees to meaningful risk. More importantly, those procedures should reflect the work employees actually perform. Generic documentation copied from another business can create significant gaps if the procedures don’t match the employer’s equipment, hazards, locations, or work practices. If your documentation has not been updated in years, reviewing your existing health and safety manual can be an important part of preparing for an audit.
Worker Training and Orientation
Training records can be an important component of an OHS audit.
An auditor may review:
new worker orientations
job-specific training
supervisor training
competency records
toolbox talks
refresher training
required certifications
Simply having a worker attend a course does not necessarily demonstrate that the worker can safely perform a particular task. Employers should consider both training and competency when evaluating their safety systems.
Businesses that need additional worker education can review Greenspine’s workplace safety training options.
What Auditors Review Beyond Policies and Procedures
An OHS audit looks beyond written policies. Auditors also review whether workers are properly trained, workplace inspections are completed consistently, and incidents are investigated in a way that leads to meaningful corrective action.
These areas help show whether a safety program is actually working in day-to-day operations. Businesses that need help strengthening these systems can review Greenspine’s workplace safety program support or explore workplace safety training options.
Worker Training & Orientation
An auditor may review:
- New worker orientations
- Job-specific training
- Supervisor training
- Competency records
- Toolbox talks
- Refresher training
- Required certifications
Course completion alone does not necessarily demonstrate competency. Employers should be able to show that workers understand the hazards, procedures, and responsibilities associated with their work.
Workplace Inspections
Regular inspections help identify hazards before they contribute to an incident.
An auditor may look for evidence that:
- Inspections happen consistently
- Hazards are properly documented
- Responsibility is assigned
- Corrective actions are tracked
- Identified issues are actually closed out
One of the most common weaknesses in safety systems is not identifying hazards. It is failing to follow them through to completion.
Incident Reporting & Investigation
Auditors may review how incidents and near misses are reported, investigated, documented, and followed up.
A strong investigation should ask:
- Was the worker properly trained?
- Was the procedure realistic?
- Was supervision adequate?
- Was the hazard previously identified?
- Was the correct equipment available?
- Were organizational factors involved?
A useful investigation should go deeper than simply concluding that an incident resulted from “worker error.”
Together, training records, inspection processes, and incident investigations provide important evidence that a health and safety program is active rather than purely administrative.
If gaps are identified in any of these areas, Greenspine can help through a WorkSafeBC compliance assessment or a free safety program review.
Workplace Inspections and Incident Investigations
Regular workplace inspections help identify hazards before they result in an incident. During an OHS audit, an auditor may look at whether inspections are happening consistently, whether hazards are documented, who is responsible for addressing them, and whether corrective actions are actually completed.
One of the biggest weaknesses in many safety systems is not identifying hazards. It is making sure the loop gets closed after the hazard has been identified.
What an auditor may look for
- Consistent inspection schedules
- Documented hazards and observations
- Assigned responsibility for corrective actions
- Clear completion deadlines
- Evidence that issues were actually closed out
A strong investigation looks deeper
An investigation should not simply end with “worker error.” The organization should examine the conditions and systems surrounding the incident.
- Was the worker properly trained?
- Was the procedure realistic?
- Was supervision adequate?
- Was the hazard previously identified?
- Was the correct equipment available?
- Were organizational factors involved?
Employers concerned about broader regulatory gaps can use a WorkSafeBC compliance assessment to identify areas that may require attention.
OHS Audit vs. Workplace Inspection
An OHS audit and a workplace inspection are related, but they are not the same thing. A workplace inspection generally focuses on conditions and practices within the workplace at a specific point in time, while an OHS audit looks at the broader safety system.
Workplace Inspection
Focuses on what is happening in the workplace now.
- Damaged equipment
- Blocked emergency exits
- Missing guards
- Incorrect PPE
- Housekeeping problems
- Unsafe work practices
OHS Audit
Looks at why those issues happened and whether the system should have prevented them.
- Why was the hazard not identified earlier?
- Was an inspection supposed to catch it?
- Who was responsible for correcting it?
- Was corrective action documented?
- Was the corrective action completed?
That broader systems perspective is one of the biggest differences between an inspection and an audit.
OHS Audit vs. COR Audit
A general OHS audit can be conducted for many reasons. An employer may want to identify weaknesses, prepare for growth, review compliance, reduce incidents, evaluate an existing safety program, prepare for a client requirement, or assess a newly acquired operation.
The Certificate of Recognition program recognizes employers that have implemented an occupational health and safety management system and successfully completed the applicable audit requirements.
In simple terms, every COR audit is a type of safety audit, but not every OHS audit is a COR audit.
Businesses preparing for certification can learn more about Greenspine’s COR audits and certification support in British Columbia.
A pre-audit review can also help identify missing documentation, inconsistent processes, training gaps, or implementation problems before the formal audit takes place.
What Happens During an OHS Audit?
Although the exact process varies, an OHS audit commonly uses several methods to collect evidence and determine whether the safety system is functioning in practice.
Document Review
The auditor may review safety manuals, policies, procedures, inspection records, training records, meeting minutes, incident investigations, corrective actions, risk assessments, and emergency plans.
Documentation can show that systems exist and have been maintained, but paperwork alone does not necessarily prove that a safety program works.
Employee and Supervisor Interviews
Workers, supervisors, and managers may be interviewed to determine whether the written safety program is understood and implemented.
For example, a manual might contain a detailed incident-reporting procedure. If employees do not know how to report a near miss, the documented process may not be functioning effectively.
Workplace Observations
Auditors may observe work activities, equipment, facilities, and workplace conditions to compare written procedures with what actually happens on the job.
An audit can expose situations where procedures say one thing while employees have developed a completely different way of doing the work.
Findings and Corrective Actions
Once the review is complete, the employer may receive findings identifying gaps or opportunities for improvement.
A useful finding should lead to a practical corrective action, responsible person, target date, and follow-up process.
Common OHS Audit Findings
Every workplace is different, but certain weaknesses appear repeatedly during health and safety reviews.
This is one reason employers should not treat a safety manual as something that is completed once and then forgotten. A safety program should change as the organization changes.
New equipment, new employees, new locations, new services, different hazards, regulatory changes, and organizational growth can all affect the program. Businesses that want ongoing support without hiring a full-time safety employee can use fractional safety consulting to help maintain and improve these systems.
How to Prepare for an OHS Audit
Preparing for an OHS audit does not mean scrambling to make the paperwork look perfect immediately before the auditor arrives. It means making sure the safety system actually functions.
Ask yourself:
- Can you demonstrate that inspections happen?
- Can you show how corrective actions are tracked?
- Do employees understand the hazards associated with their jobs?
- Are training records current?
- Do procedures reflect current operations?
- Are supervisors actively involved?
- Are incidents being investigated consistently?
If the answer to one or more of these questions is no, that gives you a clear place to start.
Employers preparing for a formal audit may also benefit from having an outside safety professional identify gaps in advance. Greenspine provides health and safety consulting services in British Columbia for businesses that need help reviewing, developing, or improving their safety systems.
Why OHS Audits Matter Beyond Compliance
An audit should not only be about passing a certification or satisfying a requirement. A useful audit can reveal weaknesses that are difficult to see during normal day-to-day operations.
Identifying these issues creates an opportunity to improve the system before they contribute to an injury, enforcement issue, failed audit, or operational disruption.
The strongest safety programs are not static. They evolve. Audits give employers another way to determine what is working, what is not, and where improvement should happen next.

Start With a Free Safety Program ReviewFrequently Asked Questions About OHS Audits
What does OHS audit mean?
OHS audit means occupational health and safety audit. It is a structured review used to evaluate whether an organization’s health and safety systems are properly documented, implemented, maintained, and effective.
What is the purpose of an OHS audit?
The purpose of an OHS audit is to identify strengths and weaknesses within an organization’s occupational health and safety system. It can reveal gaps involving training, hazard management, documentation, inspections, incident investigations, responsibilities, and corrective actions.
Is an OHS audit the same as a WorkSafeBC inspection?
No. A workplace inspection generally focuses on workplace conditions, hazards, equipment, and work practices. An OHS audit evaluates the broader safety management system, including documentation, responsibilities, training, inspections, incident management, and continuous improvement.
What documents are reviewed during an OHS audit?
Depending on the audit, documents may include safety policies, safe work procedures, hazard assessments, training records, inspection reports, incident investigations, meeting records, corrective actions, emergency procedures, and other health and safety documentation.
Who conducts an OHS audit?
That depends on the purpose of the audit. Some organizations perform internal audits, while others bring in an external health and safety professional. Formal certification audits, such as COR audits, have their own auditor and audit-process requirements.
How long does an OHS audit take?
There is no universal timeframe. The length of an audit depends on the organization’s size, number of employees and locations, complexity of operations, scope of the audit, documentation available, and type of audit being performed.
What happens if an OHS audit finds problems?
Audit findings should be converted into corrective actions. The organization can prioritize issues, assign responsibility, establish deadlines, update documentation, provide additional training, and verify that corrective actions have been completed.
Can an OHS audit help prepare for COR certification?
Yes. A pre-audit or gap assessment can help identify weaknesses in an occupational health and safety management system before a formal COR certification audit.
What is the difference between an OHS audit and a safety program review?
A safety program review can be a more flexible assessment of an employer’s existing documentation and systems. An OHS audit is generally more structured and may follow a particular audit standard, scoring system, certification requirement, or defined audit protocol.
