PUWER Assessment Tool – enabling simple & compliant assessment in-house

You have the Know-How, now you can have the Tool!

PAT – PUWER Assessment Tool – is the comprehensive iPad based assessment tool that has been used exclusively by the Machinery Safety Experts at Pilz for many years.  As PUWER compliance is an ever-present requirement, not a one-off exercise, we understand you’d like to also enable your in-house personnel to carry out assessments.  PUWER training & experience give you the know-how. Now Pilz has made PAT available to customers to give you the right tool too.

Prior to PAT, Pilz consultants fine-tuned their assessment methodology on paper across multiple industries and environments. PAT was born from the need to carry out those assessments in a more timely and efficient way for both Pilz and their customers.

PAT's Process and Output

In a nutshell, PAT enables the assessor to carry out professional and compliant PUWER assessments for single or multiple machines using a standard iPad for image capture and as the input device. Working through the PUWER Regulations 1-24 ACOP L22 (or the ACOP L112 specific Regulations for Power Presses),the software follows the guidance from ISO 12100 (Safety of Machinery – General principles for design – risk assessment and risk reduction) and allows the user to carry out a Risk Assessment utilising the Hazard Rating Numbering system (HRN).

This ensures that every aspect is covered in a tried and tested order - and nothing is accidentally left unchecked.  The system then generates and stores a comprehensive report including a high-level summary and an ‘action-required’ checklist.
