Evaluating vendor-supplied safety components and ensuring they meet the specific safety standards and guidelines for machinery use within a facility is a critical process to prevent incidents and ensure compliance. This process must be thorough and systematic and should go beyond relying solely on the vendor’s claims. It involves verifying the components’ performance, reliability, and suitability for their intended application. Here’s a detailed breakdown of the process:
The first step is to establish clear and specific safety requirements. Before purchasing any safety components, a comprehensive list of safety requirements and specifications must be created that is specific to the machinery in your facility. These requirements should be based on industry standards, legal regulations, and the company’s internal safety policies. The requirements must define the performance criteria for each component, taking into account the specific hazards and risks associated with the machine it is designed to protect. For example, if you are purchasing safety interlocks, the requirements should state the necessary performance level (PL) or safety integrity level (SIL) required to meet industry standards for that specific machine. The requirements must also include testing procedures and certification needs, that may be a requirement for your jurisdiction. This documentation of the safety requirements acts as the benchmark for evaluating any vendor-supplied component.
Next, is to require thorough vendor documentation. All vendors must be required to provide detailed documentation for each safety component. This should include, but is not limited to, design specifications, performance data, test reports, certificates of compliance, and installation and maintenance instructions. The documentation should clearly state how the component meets the specified safety requirements and standards. The documentation should also verify that any certifications from regulatory or standards organizations are authentic and up to date. For example, for a safety relay, the documentation must include the SIL or PL rating, the operating conditions, and all functional and electrical testing results, along with any certificates that the component meets relevant safety standards. The documentation is critical to begin verifying if the components meet all the required safety standards.
The next step is conducting a detailed documentation review. Once the vendor has supplie....
