Occupational Risk Assessment: How to Apply It Effectively!

Workplace safety is a fundamental concern in any professional environment. Every year, thousands of accidents occur in workplaces, leading to :

  • injuries,
  • financial losses,
  • and production interruptions.

Yet, many of these accidents could be prevented through a rigorous assessment of occupational risks. That’s what we will explore in this article!

Occupational Risk Assessment:

Occupational risk assessment is an essential step in identifying and reducing risks in the workplace.

It’s a systematic process aimed at identifying, evaluating, and controlling risks present in the workplace to protect workers from injuries, illnesses, and other hazards.

Occupational risk assessments should be conducted by qualified individuals, such as safety engineers or occupational physicians. The process of occupational risk assessment includes the following steps:

  • Data Collection: The evaluator must gather information about the workplace, including activities performed, machinery and equipment used, chemicals handled, and environmental conditions.
  • Risk Identification: The evaluator should identify all types of risks, including physical, chemical, biological, ergonomic, psychosocial, and organizational risks.
  • Risk Assessment: Risks identified are assessed in terms of severity and likelihood.
  • Risk Mitigation: The evaluator must implement preventive measures to reduce the identified risks. These preventive measures may include changes in work processes, the use of personal protective equipment, worker training, and modifications to the work environment.

Occupational risk assessment is a legal obligation for employers in France and is considered a best practice for any company that wants to improve the safety of its workers.

Why is it important?

Understanding Workplace Risks:

The first step in ensuring workplace safety is to understand the risks your employees might be exposed to in their professional environment. These risks can vary significantly depending on the industry and job roles. By taking the time to identify them, you are better prepared to prevent and respond to them appropriately.

Risk assessment helps you recognize potential hazards, from physical to psychosocial risks, as well as chemical and environmental risks. It also enables you to assess the likelihood of these risks materializing and their impact on your employees’ health and safety.


Beyond the moral and ethical aspect of protecting workers’ health and safety, strict regulations are in place to govern the assessment and management of occupational risks. This regulation is aimed at protecting the rights of your employees and ensuring that as an employer, you take all necessary measures to minimize risks.

Your employees have the right to work in a safe and healthy environment, and it is both your responsibility and their right to ensure that this is upheld. Non-compliance with regulations can have serious consequences for your business, ranging from financial penalties to closure.

What are the 6 major categories of occupational risks?

It is essential to understand these categories to implement effective prevention measures in your company.

  • Physical Risks:

These risks include accidents related to physical elements, such as falls, handling accidents, and injuries caused by equipment.

  • Chemical Risks:

They result from exposure to hazardous chemicals, whether through inhalation, skin contact, or ingestion.

  • Biological Risks:

These risks arise from exposure to biological agents, including viruses, bacteria, and molds. This mainly concerns the healthcare and research sectors.

  • Ergonomic Risks:

They are related to working conditions, posture, and repetitive movements that can lead to musculoskeletal disorders.

  • Psychosocial Risks

These risks affect the mental well-being of workers and encompass stress, harassment, excessive workloads, and professional conflicts.

  • Workplace Environment-Related Risks:

These include working conditions such as air quality, temperature, noise, and lighting, which can impact employee health.

What are the 5 steps for implementing an occupational risk assessment?

  • Step 1: Hazard Identification

The first step is to identify all the hazards present in your professional environment. This may include hazardous equipment, harmful chemicals, specific working conditions, or other factors that could compromise worker safety. It’s essential to exercise due diligence and examine all aspects of your business.

  • Step 2: Risk Assessment

Once hazards are identified, you need to assess the risks associated with each hazard. This step involves determining the likelihood of the hazard occurring and the severity of consequences in the event of an incident. This assessment allows you to prioritize risks and determine where to focus your prevention efforts.

  • Step 3: Implementation of Preventive Measures

After identifying and assessing the risks, you must implement preventive measures to minimize these risks. This may involve altering work procedures, adding safety equipment, providing employee training, or taking other actions aimed at eliminating or mitigating risks.

  • Step 4: Monitoring and Control

Risk assessment is not a one-time task. You need to establish an ongoing monitoring and control system to ensure that preventive measures are working as intended. This may include regular inspections, safety audits, and data collection to evaluate the effectiveness of the actions taken.

  • Step 5: Review and Update

Finally, it’s essential to regularly review and update your risk assessment based on changes in your business. New hazards may emerge, work procedures may evolve, or new technologies may be introduced. An occupational risk assessment must remain relevant to be effective.
