Protect people without making safe recovery unnecessarily difficult.
Machine safety combines physical guarding, interlocks, emergency stops, light curtains, scanners, safety controllers, and safe motion functions to reduce exposure to machine hazards while supporting controlled operation, access, and recovery.
Build the operating system around real production conditions.
Controls, safety, communications, diagnostics, machine behavior, maintenance, and operator response should all support stable production rather than function as separate layers.
Reliable systems make abnormal conditions easier to manage.
Good design considers faults, communication loss, changes in demand, maintenance, safe recovery, operator access, and performance visibility before the equipment reaches production.
CRIT-AHazard Definition
Safety design begins with the hazardous motion or energy, the access required, and the operating modes that expose people to risk.
CRIT-BAccess Strategy
Fixed guards, interlocked doors, light curtains, scanners, and collaborative operation support different kinds of operator and maintenance access.
CRIT-CSafety Logic
Emergency stops, guard switches, safe torque off, safe speed, and safety PLC functions should have clearly defined safe states and reset behavior.
CRIT-DRestart & Recovery
The system should prevent unexpected restart while still giving operators a clear path to verify the area and resume production safely.
Visualize the control and operating relationships.
Each page uses distinct technical diagrams focused on the specific control, safety, or operational relationship involved.
Safety zone.
The safe boundary should account for hazardous motion, stopping distance, access points, and the location of sensing devices.
Safety chain.
A complete safety function connects detection, safety logic, and a verified safe machine response.
Relevant controls and production resources.

Machine safety should define what the machine is allowed to do in every access state. Hazards, guarding, sensing, safety logic, safe motion, reset behavior, and recovery all shape practical operation.
