WALMART MAINTENANCE Preventive Maintenance 2 — Questions and Answers
Question 1: What is predictive maintenance?
- Predicting when new equipment will be needed
- Using condition monitoring data and analytics to predict when equipment will fail and scheduling maintenance accordingly (Correct answer)
- Maintaining equipment on the manufacturer's exact schedule
- Replacing equipment before it is installed
Correct answer: Using condition monitoring data and analytics to predict when equipment will fail and scheduling maintenance accordingly
Predictive maintenance uses actual equipment condition data (vibration, temperature, etc.) and analytics to predict failures, optimizing maintenance timing.
Question 2: What is the purpose of a building envelope inspection?
- To check the mailbox
- To assess the condition of the roof, walls, windows, and doors that protect the interior from weather (Correct answer)
- To inspect the building's documents
- To review the building's insurance policy
Correct answer: To assess the condition of the roof, walls, windows, and doors that protect the interior from weather
The building envelope includes all components that separate interior from exterior (roof, walls, windows, doors). Inspecting it identifies water intrusion, insulation, and structural issues.
Question 3: What should be included in a seasonal maintenance checklist for spring?
- Only snow removal equipment storage
- HVAC switchover to cooling, roof inspection for winter damage, exterior painting assessment, and landscaping startup (Correct answer)
- Holiday decoration removal only
- Nothing, spring requires no maintenance
Correct answer: HVAC switchover to cooling, roof inspection for winter damage, exterior painting assessment, and landscaping startup
Spring maintenance addresses the transition from heating to cooling season, repair of any winter damage, and preparation of exterior areas for warm weather.
Question 4: What is the purpose of maintaining an equipment asset registry?
- To impress corporate visitors
- To track all equipment including location, model, serial number, warranty, and maintenance history (Correct answer)
- To count the number of assets for tax purposes only
- To satisfy fire department requirements
Correct answer: To track all equipment including location, model, serial number, warranty, and maintenance history
An asset registry provides essential information for maintenance planning, warranty tracking, replacement budgeting, and emergency response when equipment identification is needed.
Question 5: What is the recommended practice for maintaining roof drains?
- Ignore them unless there is a leak
- Inspect and clear debris from roof drains regularly, especially before rain season (Correct answer)
- Cover them to prevent debris entry
- Replace them every year
Correct answer: Inspect and clear debris from roof drains regularly, especially before rain season
Regular inspection and clearing of roof drains prevents water ponding on the roof, which can cause structural damage, leaks, and premature roof deterioration.
Question 6: How should you prioritize multiple maintenance work orders?
- First come, first served
- By safety impact first, then business impact, then convenience (Correct answer)
- By easiest task first
- Randomly to ensure fairness
Correct answer: By safety impact first, then business impact, then convenience
Safety-related maintenance always takes priority, followed by issues that impact business operations (e.g., sales floor equipment), then less urgent maintenance tasks.
