Machine Safety Validation

Does your safety system perform the way it's supposed to?

Machine safety validation proves your guards and safety devices work reliably, before an incident forces you to find out the hard way.

The Risk of an Unvalidated Safety System

Without validation, you're trusting that safety devices installed months or years ago still work as intended. Modifications, wear, electrical issues, or improper settings can compromise protection and expose your operators to threats.

How Machine Safety Validation Works

  1. Documentation Review
    1. We start by reviewing existing safety documentation to understand what protection is supposed to be in place, including:
      1. Risk assessments
      2. Electrical schematics
      3. Safety device specifications
      4. Any previous modifications 
  2. On-Machine Validation
    1. We validate the machine in real operating conditions. This includes actively testing how the machine responds when safety devices are triggered.
  3. Comprehensive Safety Function Testing
    1. Testing is customized to the type of guarding and safety devices in place. We validate based on how the device is supposed to protect people, not just that it's installed.
  4. Detailed Reporting & Recommendations
    1. You receive documentation of what was tested, how it was tested, the results, and actionable recommendations if gaps are identified.

Validation Testing We Perform

The testing process will depend on the type of guarding and safety devices in place, but the goal is always the same: to prove the safety functions work reliably and consistently.

  • Motion Interruption
    • Verifying safety devices interrupt motion when activated
  • Restart Behavior
    • Checking restart behavior after a safety event
  • Device Performance
    • Confirming safety switches, radars, light curtains, scanners, 2-hand controls, and e-stops perform correctly
  • Stop Time Validation
    • Validating stop times when required
  • Fault Response
    • Ensuring safety circuits behave properly during faults or power loss


Helping You Find AND Fix the Problem

Our approach is different from "inspect and report" companies. If a guard or safety function fails validation, we don't just write it up and walk away.

  • Clear Explanation
    • We explain why the safety system failed and what needs to change to fix it.
  • Actionable Solutions
    • This might include adjusting device placement, correcting wiring or logic, improving stop performance, or recommending different safety solutions entirely.
  • Execution Support
    • Recommendations can be executed by your team or by us.

We'll coordinate timing to fit your operational needs, including off-shifts and maintenance windows.


What's Included in Your Validation Report

  • Machine & Safety System Overview
    • Complete documentation of equipment and protection measures in place.
  • Test Methods Used
    • Detailed explanation of how each safety function was validated.
  • Pass/Fail Results
    • Clear results for each safety function and device tested.
  • Identified Gaps
    • Documentation of any deficiencies or vulnerabilities discovered.
  • Corrective Action Plan
    • Specific, actionable recommendations to address issues.

Our report is structured to support OSHA compliance expectations and ANSI standards, the kind of documentation you want ready for audits or investigations.

Frequently Asked Questions

How long does a machine safety validation take?

  • Most validations are completed in one day per machine, depending on complexity. 
  • Simple guarded standalone machines are quicker, while a robotic cell or integrated production line takes more time because there are more safety functions to verify.

What happens if a guard or safety device fails validation?

  • We explain why it failed and provide actionable recommendations to fix it. 

How much machine downtime should we expect?

  • The validation process requires short, controlled interruptions, but it doesn't usually mean hours of lost production. 
  • We can schedule work during off-shifts, weekends, or scheduled maintenance windows to minimize impact. 

Is the validation report formatted for OSHA?

  • While the report isn't written specifically for OSHA, it's structured to support OSHA compliance expectations and recognized industry standards such as ANSI, with a focus on legacy machine risk-reduction measures. 

What do we need to prepare before validation begins?

  • You'll need to: 
    • Have electrical prints and safety technical documents available
    • Ensure the machine is in normal operating condition
    • Let operators or maintenance know when validation is scheduled
    • Note any changes that may not be documented
