Construction Materials – Clay Extrusion Silo Safety- Whole Body Access & The Escape Release
This case study looks at a Clay Extrusion Silo safety and how the right interlocking solution was chosen. When designing a safeguarding solution, the best risk reduction measure is to design out risk. Whole body access is where an operator can be completely inside the safeguarded space, this can be incredibly dangerous. If there is risk of an operator becoming trapped inside a safeguarded space, make sure the space has good visibility from the point of manual reset. If this isn’t possible, mechanical measures can be considered to prevent operators becoming trapped and hazards unexpectedly restarting.
In this case study we take a look at a safeguarded entry with good visibility and how the solution is designed with ‘what if’ in mind.
Access to The Clay Extrusion Silo is protected with an interlock with guard locking. The interlock has a solenoid which forces a run-down time before entry is allowed. When the run-down time is complete, the locking mechanism within the interlock can be ‘unlocked’ and the entry to the safeguarded space can be opened.
In this scenario, the clay extrusion silo is surrounded by a mesh fence, from which a relatively good view of inside the safeguarded space can be achieved. As the chance of being trapped inside this safeguarded space cannot be guaranteed, an escape release has been designed into the interlock actuator for quick escape in an emergency.
