Machine Safety Risk Assessment Checklist

Safeguard your manufacturing environment and increase employee safety with a proper machine risk assessment. elobau has outlined questions that should be considered when assessing mechanical hazards and occupational risks. Our risk assessment is intended to serve as a general-purpose overview of precautions to take when safeguarding your workspace. We recommend consulting a risk assessor or safety professional for your specific safety equipment needs. elobau is not liable for any issues that may arise due to a lack of proper hazard identification or risk management.

Machine Risk Assessment Considerations

  • What is the intended use of this machine?
  • Is the mean number of annual operations (Nop) defined?
  • Have the tasks been defined for the equipment and its intended use?
  • Have associated operating hazards been identified when working with the equipment?
  • Have all hazardous motions been identified?
  • Have all power sources been identified (electrical, hydraulic, pneumatic, gravitational)?
  • Who is responsible for the safety of the equipment?
  • Have all out devices (OTE) been identified (actuators, motors, valves)?
  • Has process protection been considered when using the equipment?
  • Will multiple workers be using this equipment?
    • Have they been trained?
    • Do they know the hazards involved with operating this equipment?
    • Will additional training be required for risk reduction?
  • When and how is the equipment maintained?
  • Is Lock out / Tag out process defined?
  • Do residual risks exist when power sources are removed?
  • Have maintenance personnel been trained and informed of residual risks?
  • Have additional provisions been taken to limit their exposure to residual hazards (press blocks, mechanical stops, enabling devices, PPE)?
  • Has the manufacturer-supplied safety device been installed?
    • Are they sufficient for required safety in the application?
    • Are they properly functioning?
    • Have they been validated in accordance with relevant safety standards (ISO13849-2)?

Machine Safety Risk Assessment for Tasks and Equipment

  • Is the person doing the risk assessment an expert at operating the equipment?
  • Have Hazard Discover Strategies been implemented?
  • Professional Machine Safeguarding Audits
  • Machine Risk Assessment Process (ANSI B11, ISO 12100)
  • Plant Walkthroughs
  • Does the risk assessor understand all the tasks required of the equipment?
  • Individual Audit
  • Team task-based Audit
  • IS there additional information that can assist with the process of risk assessment?
  • plant layouts
  • power transmission schematics
  • operator manuals
  • modification documents
  • operator tasks
  • maintenance tasks/schedule
  • Who should be available during a risk assessment?
  • Safety Professional (Functional Safety Engineer)
  • Machine operators
  • Maintenance personal
  • Supervisors
  • AHJ (Authority Having Jurisdiction)
A risk assessment is only as good as the information provided at the time of the assessment. You cannot protect from the unknown.


Machine Risk Assessment for Safety Devices and Functions

  • Are the existing safety devices in compliance with required safety standards (i.e. ISO, ANSI, IEC, OSHA, UL)?
    • What are the required functions for mediating Risk?
  • What is the severity of injury if exposed to the hazard?
    • S1 Slight – i.e. normally reversible Injury (Note: wording matches ISO13849-1)
    • S2 Serious-i.e. normally irreversible injury, death
  • What is the frequency (F) and/or exposure to the hazard?
    • F1- Seldom-to-less-often and/or exposure time is short.
    • F2- frequent-to-continuous and/or exposure time is long
  • What is the possibility (P) of avoiding hazards or limiting the harm?
    • P1- possible under specific conditions
    • P2- scarcely possible
  • Are the existing safety devices and safety functions designed for Performance Level required? (PLr)
