Industrial Press Safety Operation Procedures: Complete Compliance Guide

## Introduction Industrial presses — including hydraulic, mechanical, and pneumatic types — are high-risk equipment requiring strict safety protocols. This guide is based on Chinese national standards including GB requirements for mechanical press safety and JB technical conditions for hydraulic press safety, applicable to all types of industrial presses. ## Phase 1: Before Starting Work ### Personal Protection 1. Wear complete personal protective equipment (PPE) before starting the shift. 2. Safety helmets are mandatory — secure chin straps properly. 3. Use appropriate ear protection in high-noise environments. 4. Wear snug-fitting clothing; no loose sleeves, ties, or jewelry that could be caught in machinery. ### Equipment Inspection 1. **Lubrication System**: Verify the lubrication system is functioning properly. Check oil levels and pump operation. 2. **Fastener Check**: Inspect all bolts and screws for tightness. Pay special attention to die mounting fasteners. 3. **Safety Devices**: Verify all safety guards, light curtains, two-hand controls, and interlocks are intact and functional. 4. **Die Inspection**: Confirm dies are firmly mounted, properly matched, and free of cracks. Verify the overload protection device is operational. 5. **Immediate Repairs**: Any issues found during inspection must be repaired before starting operation. ## Phase 2: During Operation ### Team Coordination - Follow the instructions of the team leader and press controller. - Coordinate actions with all team members. Maintain clear communication. - When transferring and placing workpieces, maintain full concentration. Place parts stably and accurately. ### Critical Safety Rules 1. **No Body Parts in Die Zone**: During press operation, no part of the operator's body may enter the die area or contact moving components. 2. **No Die Changes During Rotation**: When the flywheel is rotating, do not change or adjust dies, and do not perform any press maintenance. For such work:/n - Turn the main power switch key to the OFF position and remove the key. - Disconnect the power supply. - Close the air supply. - Wait for the flywheel to come to a complete stop. 3. **Stop on Malfunction**: If any transmission mechanism, safety device, or safety control circuit fault is detected, cease operation immediately. All repairs must follow the manufacturer's service manual. 4. **Material Handling**: Billet sections and slugs must be placed in designated bins or pits. Any material spilled on the floor must be cleaned immediately for everyone's safety. ### Critical Safety Precautions - When starting the main press drive, ensure the ladder safety lock is in the DISENGAGED position. - Remove all tools and unnecessary parts from the press work area. Maintain a clean workspace. - All personnel except the designated operator must stay clear of the work area. No one may stand on the crossbeam. - Follow the operating procedures specified in the equipment manual at all times. - **CRITICAL**: All interlock circuits are essential for safe press operation. It is absolutely forbidden to bypass any interlock circuit or modify the electrical wiring. - Never operate the press with the electrical cabinet door open. ## Phase 3: After Work Completion 1. Shut off water, air, and electrical supplies following the correct sequence. 2. Clean the equipment and work area thoroughly. 3. Inspect the work environment for any hazards. 4. Complete the shift handover process properly and fill out the shift record. 5. Report any abnormalities encountered during the shift to the next shift and to supervision. ## Regulatory Compliance Notes This safety protocol complies with:/n- GB requirements for mechanical press safety - JB technical conditions for hydraulic press safety Operators should verify that their specific equipment model meets all applicable national and industry standards before operation.
