High-risk machinery such as stamping presses, robotic arms, and automated conveyor belts poses significant workplace hazards. Ensuring machine safety with pressure-sensitive safety mats prevents accidents by automatically stopping machinery when a person steps into a hazardous area. These safety solutions help manufacturers comply with global standards like OSHA and ISO 13849 while maintaining productivity.
This article covers why pressure-sensitive safety mats are essential for maintaining industrial machine safety, how they work, and how to integrate them effectively.
What Are Pressure-Sensitive Safety Mats?
Pressure-sensitive safety mats are protective floor sensors installed around hazardous machinery. They detect when a person steps on them, triggering an immediate stop signal to the connected machine. This prevents accidents by halting dangerous operations before injuries occur.
How They Work:
- Detection Zone Setup: Mats are placed around machines, forming a protective zone.
- Activation Trigger: Stepping on the mat triggers sensors to detect weight.
- Machine Shutdown: The system halts machine operations instantly, protecting workers.
Example: Automotive plants use safety mats around robotic workstations to stop machinery when workers enter restricted areas.
