Risk Assessment: The Step-by-Step Method to Make Your Company Safer

How to assess risk in the workplace: method and key tools. 

In short: the step-by-step method to secure your business through risk assessment

• Understand the difference between hazard and risk: a hazard is the source of potential harm, while risk combines the likelihood of occurrence and the severity of consequences.
• Identify all risks specific to your activity: analyze health, technological, psychosocial, or environmental risks based on your sector.
• Comply with regulations and document everything in the DUERP: keep an up-to-date document listing risk situations, actions taken, and follow-up.
• Use a structured method: detect hazards, assess criticality, prioritize using a risk matrix, then develop and monitor an appropriate action plan.
• Involve all employees: raise awareness, provide training, collect field feedback, and promote continuous improvement for sustainable, shared safety.

Who hasn’t heard of “risk assessment” at work without truly understanding how it works?Taking the time to analyze each hazard, anticipate exposures, and define proper preventive measures is more than a formality — it’s the foundation of long-term workplace safety.

The distinction between hazard and risk must be clear from the outset.A hazard is a potential source of harm — a machine, a chemical substance, or even a flawed work organization. You need to participate to the safety day.Risk, on the other hand, combines the probability that an adverse event will occur and the severity of its impact on health or safety.A poorly protected worker handling toxic substances? That’s when the full concept of risk becomes clear.

There are several types of risks to assess in a workplace:

• Physical risks (falls, cuts, noise…)
• Chemical risks (exposure, inhalation, contact…)
• Biological risks (viruses, bacteria…)
• Psychosocial risks (stress, harassment, work overload…)
• Organizational risks (workload, lack of procedures…)

The first step of an effective approach? Identify both actual and potential hazards in every workplace and for every worker, regardless of industry or activity.

Regulatory Obligations: Overview and Compliance

In France, regulations require all employers to create a Single Risk Assessment Document (DUERP).This document formalizes the assessment of all professional risks, outlines preventive actions, and must be updated at least annually or after any significant organizational change.

Why does this framework exist? To protect every employee’s health and safety, and to ensure risk management remains a top priority.

Labor inspections, traceability requirements (risk registers, evaluation reports, indicators), and the involvement of the CSE (Social and Economic Committee) are part of daily life in all types of companies, from industry to services.

The Steps of a Risk Assessment Process

Identifying Hazards and Risks

Start by identifying each hazard in the workplace through:

• Observing workstations
• Conducting interviews with employees
• Analyzing accident, incident, and near-miss situations
• Reviewing documents (safety sheets, reports, audits…)

Risk Analysis and Prioritization

Assess each risk by cross-referencing probability and potential severity.This step often relies on a risk matrix — a visual tool to classify risks from lowest to most critical.

Each situation is given values for:

• Probability: low, medium, or high
• Severity: low, medium, or high

Implementing and Monitoring Preventive Measures

Once priorities are set, develop a clear and realistic action plan.This can include buying new protective equipment, reorganizing workflows, conducting training, awareness campaigns, or establishing specific procedures.

Follow-up is just as important as the initial implementation:

• Monitor the effectiveness of measures
• Reassess risks regularly
• Update the DUERP accordingly

Key Tools and Methods for Effective Risk Assessment

The Risk Matrix

An essential tool for effective prioritization.By combining severity and probability, the matrix helps make quick, informed decisions.It's a double-entry table where each risk is positioned based on its danger level.

This visualization helps businesses focus on what really matters and manage priorities according to real conditions on the ground.

Digital Tools and Risk Assessment Software

Many software solutions help formalize, monitor, and update the DUERP.From platforms like OiRA, SafetyCulture, tailored business apps, or customized Excel sheets — every company can find tools suited to their workforce and risk type.

Key features include:

• Automatic report generation
• Update alerts
• Real-time information sharing
• Secure data archiving

Feedback and Team Participation

You must assess workplace risks, but nothing is more effective than collective involvement.Encourage information sharing, organize risk identification workshops, and rely on field observations.Sharing concrete examples, real-life situations, or employee-driven solutions helps the entire system evolve.

Ongoing Monitoring, Updates, and Optimization

Formalization, Updates, and Oversight

The DUERP must be a living document, regularly reviewed and updated:

• After each major event (accident, reorganization, new activity…)
• With each newly identified risk
• By evaluating the effectiveness of completed actions
• While archiving previous versions

A Continuous Improvement Approach

• Risk management should never become stagnant.
• Organize regular internal audits
• Learn from other companies’ feedback
• Run training sessions tailored to emerging risks
• Implement performance tracking indicators

“Every new analysis, every audit, every prevention workshop is another step toward full control of workplace risks.”

Practical Tips for a Successful Approach

Start with a simple evaluation in a pilot department, then expand.

Involve every employee, from field workers to leadership.

Use appropriate tools, digital or paper, to ensure traceability and control.

Keep in mind: worker health and safety is always the top priority.

Adapt your methods to industry changes and regulatory updates.

FAQ: Understanding Risk Assessment

What is risk assessment?

Risk assessment is a key workplace process that involves identifying every hazard that could threaten health and safety.It uses structured methods to analyze work situations, assess likelihood and severity, and propose preventive measures.

With the DUERP, companies place safety and health at the heart of their priorities.Risk assessment ensures constant control, reduces exposure, and guarantees optimal conditions — it’s the basis of any effective action!

What are the 4 types of risks?

In the workplace, four main types of risks are commonly assessed:

• Physical risks (falls, noise, machines)
• Chemical risks (hazardous product exposure)
• Biological risks (bacteria, viruses)
• Psychosocial risks (stress, harassment)

Each risk type comes with its own severity, probability, and specific management method.

The goal: tailor every prevention measure to the nature of the hazard and document it in the DUERP for optimal safety.

What are the 5 key steps of a workplace risk assessment?

To effectively assess workplace risks, five essential steps are:

• Identify hazards in every activity or department
• Analyze risk situations and estimate severity/probability
• Rank risks to prioritize actions
• Implement appropriate preventive measures
• Monitor, regularly update the DUERP, and reassess after changes

This structured process ensures safety, health, and risk control for all employees — it's the standard method for improving working conditions.

How do you assess the risk of a specific action?

To assess the risk of a professional activity, start by identifying the hazard linked to the action.Then analyze the likelihood of occurrence and severity of consequences for workers or the business.

Using tools like a risk matrix or qualitative analysis, employers and safety teams can determine a clear risk level and choose the right control measures based on the specific context.

What is the purpose of risk assessment?

The goal is simple: protect the health and safety of every person at work.The process aims to identify hazards, analyze each situation, and implement effective preventive measures.

The professional objective: reduce the chance of accidents, improve working conditions, and ensure regulatory compliance (labor law, ISO standards, etc.).By prioritizing prevention, companies control risks, improve project management, and create a lasting improvement in workplace conditions.

What are the main risk assessment tools?

Several tools are used for risk assessment:

• DUERP (Single Risk Assessment Document) — the foundation of all prevention plans
• Risk matrix — to match severity and likelihood
• Sector-specific assessment grids
• Specialized software, evaluation reports, or checklists
• Documentation and tracking systems (registers, databases)

Each tool fits into a larger risk management system to ensure effective prevention and continuous control in the workplace.
