In the industry, safety and risk evaluations are critical to guaranteeing worker well-being and overall operational efficiency. Manufacturers can reduce possible dangers and provide a safer working environment by accurately analyzing risks, adopting appropriate measures, and adhering to industry regulations. This blog seeks to provide additional information on the relevance of safety and risk evaluation in can manufacturing, focusing light on critical elements like risk tolerance, risk assessment methodology, and the value of detailed risk analysis.
Understanding risk tolerance is a fundamental step in the risk evaluation process. Risk tolerance refers to the level of acceptable risk for a particular industry, which can vary widely. Determining risk tolerance requires careful consideration, enabling manufacturers to identify the appropriate risk reduction measures. The objective is to reduce risk to a level at or below the maximum risk tolerance defined by the manufacturer.
Estimating risk in an automation environment involves utilizing specific methodologies. While there are multiple methodologies out there, below are the two most common.
- ANSI B11.0 – This is one of the most widely used methodologies. It is a two-factor system established by the American National Standards Institute (ANSI). It assesses risk severity and risk probability, each with four potential levels.
- ANSI / RIA R15.06 – Another commonly employed methodology is ANSI / RIA R15.06. It employs a three-factor system involving risk severity, exposure to risk, and the possibility of avoidance, each with two possible levels.
When selecting a risk ranking methodology, ensuring that it offers the required level of detail for the size of the implemented safety system is crucial. ANSI B11.0 offers additional options for risk ranking systems in its annex.
After setting risk tolerance and choosing a suitable risk ranking methodology, the next step is risk analysis in the assessment process.
ANSI B11.0 and ISO 12100 are the prevailing standards in the United States and Europe, respectively, for conducting risk assessments. All manufacturers should follow these standards, as well as industry-specific risk assessment standards, during the risk assessment process.
Thorough risk analysis allows for a comprehensive understanding of potential hazards, empowering manufacturers to implement effective risk reduction measures.
The importance of conducting a comprehensive risk assessment cannot be overstated. Skipping this crucial step or failing to perform a diligent risk assessment may lead to inadequate risk reduction measures or broadly defined safety system requirements. Such oversights can jeopardize the safety of machine users and result in inefficient allocation of resources. Can manufacturers should prioritize the proper analysis of risk. This includes applying suitable risk reduction measures to ensure a safe working environment and optimize operational efficiency.
