Risk Assessment Matrix And Hierarchy Of Control Chart
When it comes to workplace safety, risk assessment is a crucial step. It involves identifying potential hazards and evaluating the level of risk they pose to employees. A risk assessment matrix is a tool used to visualize and prioritize these risks. It’s a simple chart that helps you decide which hazards require immediate attention and which can be addressed later.
What Is A Risk Assessment Matrix?
A risk assessment matrix is a chart that helps you determine the level of risk associated with a particular hazard. It’s typically divided into two variables: the likelihood of a hazard occurring and the severity of its consequences. By plotting these variables on the matrix, you can determine the level of risk associated with each hazard.
The likelihood of a hazard occurring is often measured on a scale from 1 to 5, with 1 being unlikely and 5 being almost certain. The severity of its consequences is often measured on a scale from 1 to 5 as well, with 1 being minor and 5 being catastrophic. By multiplying these two variables, you get a risk score that helps you prioritize which hazards to address first.
How To Use A Risk Assessment Matrix
Using a risk assessment matrix is simple. First, identify the hazards in your workplace. Then, assess the likelihood of each hazard occurring and the severity of its consequences. Plot each hazard on the matrix, using the likelihood and severity scales to determine its risk score.
Once you’ve plotted all the hazards, prioritize them based on their risk scores. Hazards with high risk scores should be addressed immediately, while hazards with lower risk scores can be addressed later.
Hierarchy Of Control Chart
The hierarchy of control chart is another tool used to manage workplace hazards. It’s a framework that helps you determine the most effective way to control a hazard. The hierarchy of control is often presented as a pyramid, with the most effective controls at the top and the least effective controls at the bottom.
The Five Levels Of Control
The hierarchy of control chart is divided into five levels of control:
- Elimination: This involves completely removing the hazard from the workplace.
- Substitution: This involves replacing the hazard with something less hazardous.
- Engineering Controls: This involves modifying the workplace or equipment to reduce the risk of the hazard.
- Administrative Controls: This involves changing work practices or policies to reduce the risk of the hazard.
- Personal Protective Equipment (PPE): This involves providing employees with personal protective equipment to reduce the risk of the hazard.
How To Use The Hierarchy Of Control Chart
Using the hierarchy of control chart is straightforward. First, identify the hazard you want to control. Then, work your way up the pyramid, starting with elimination and working your way down to PPE. Choose the most effective control measure that is feasible for your workplace and implement it.
It’s important to note that PPE should be seen as a last resort. While it can be effective in reducing the risk of a hazard, it should not be relied upon as the only control measure. The hierarchy of control chart encourages employers to prioritize more effective control measures over PPE.
Conclusion
Risk assessment and hazard control are essential components of workplace safety. A risk assessment matrix and hierarchy of control chart are two tools that can help you manage workplace hazards effectively. By using these tools, you can identify and prioritize hazards, and implement control measures that reduce the risk of harm to your employees.
