Daily
Weekly
Quarterly
Every 6-month
Annually

Maintenance technician
Production Leader
Operator working on this equipment
Production manager
Process engineer
What is the purpose of MESlP for existing equipment?
To enhance aesthetic design
To increase production speed
To reduce manufacturing cost
To identify safety gaps and develop improvement plans
What does the acronym "HRN" stand for in the context of equipment safety?
Hazard Risk Notification
Hazard Review Note
Hazard Recognition Number
Hazard Rating Number
A manufacturing facility identifies a machine with a high HRN value due to frequent worker exposure to a hazardous moving part. The company plans to reduce the HRN using different control measures. Which of the following actions would result in the greatest reduction of HRN?
Implementing a strict PPE policy requiring workers to wear gloves and safety glasses at all times
Adding an interlocked safety guard that prevents machine operation when open
Conducting additional training sessions on safe machine operation and hazard awareness
Rotating workers every hour to limit individual exposure to the hazard.
What is the risk level goal when doing risk assessment and HRN?
Low risk
Medium risk
Zero risk
Negligible
A maintenance worker is servicing a hydraulic press when it suddenly activates, causing a serious injury. An investigation finds that the worker had followed some safety procedures but missed a critical LOTO step. Which of the following failures most likely led to the accident?
The machine was tagged out, but maintenance was completed faster than expected.
The technician forgot to wear insulated gloves while handling electrical components.
The machine’s warning lights were not functioning properly.
The worker did not verify the absence of stored energy after locking out the main power source.
Below are the purposes of MESIP, except:
Identify compliance of two-handed safety control for legacy equipment
Confirm light curtain and associated fixed guarding are adequate to prevent employees accessing the hazard
Upgrade the equipment with latest technology
Identify safety gaps and improvement opportunities for legacy, existing machine and equipment purchased prior to January 1, 2016
What are the residual risks?
Risks that are completely eliminated
Risks that remain after all mitigation efforts have been implemented
Risks that are ignored
Risks that are unknown
What is the aim for HRN in the HRN process for new machinery and equipment?
To reduce costs
To increase production speed
To enhance employee satisfaction
To ensure safety compliance
