Provide Solution offers a new important service, machinery safety. Expanding our skills and staying constantly updated to consistently improve performances are two fundamental concepts for our team.
Machinery safety involves a 4-step process:
Step 1: Risk Assessment
The initial phase of securing a machine is risk assessment. This phase is crucial to identify existing hazards, evaluate their severity, and includes:
- Assessment of RESS according to the Machinery Directive and their applicability: Risk Elimination and Substitution Strategies (RESS) are strategies for eliminating and substituting risks. Assessing RESS helps pinpoint the most effective strategies to reduce risks.
- Verification of the applicability of current regulations: Risk assessment must consider current regulations regarding machinery safety.
- Identification and evaluation of existing hazards: Risk assessment must identify all hazards present in the machine.
- Estimation of hazard levels for all machine life stages: Risk assessment must consider hazards throughout the machine’s life stages, from design to maintenance.
- Recommendations on methods or procedures to eliminate or mitigate risk: Risk assessment should provide recommendations on measures to adopt for risk reduction.
Step 2: Safety Systems Design
Once hazards are identified, it’s necessary to design safety systems to eliminate or mitigate them. Safety systems can be mechanical, electrical, or software-based.
Safety system design should include the following activities:
- Selection of the most appropriate safety systems: Selection should be based on existing hazards and current regulations.
- Design of safety systems from mechanical, electrical, and software perspectives: Design should encompass technical, mechanical, electrical, and software aspects of safety systems.
- Integration of safety systems into 3D models, electrical diagrams, or machine management software: Safety systems must be integrated into 3D models, electrical diagrams, or machine management software.
Step 3: Calculations and Validation of Safety Functions
After choosing safety systems, it’s necessary to validate the choice through calculations and validation of safety functions. Safety calculations determine the safety level (PL) achieved by safety functions.
If the chosen method involves introducing electrical devices and software management, validation of the achieved PL and software management of related signals must be done using specialized software (Sistema). Writing PL calculations with Sistema software and validating your process’s software must comply with EN13849-1/2 regulations.
Safety validation ensures that safety functions operate correctly under all usage conditions.
Step 4: Installation and Testing
The final step in securing a machine is the installation and testing of safety systems, performed by qualified personnel to verify proper functioning under all usage conditions.
Provide Solution offers a comprehensive and complete machinery safety service covering all stages of the process, from risk assessment to design, calculations, and validation, to supply, installation, and testing.
