Extreme Temperature Life Energy Wheel Checklist

This checklist is designed to ensure safety and proper procedures when operating equipment in extreme temperatures (both hot and cold). It covers pre-operation, during operation, and post-operation checks to mitigate risks associated with temperature extremes.

I. Pre-Operation Checks

A. General

• Review weather forecast for extreme temperature warnings.
• Ensure all personnel are trained on recognizing and responding to heat or cold stress symptoms [1].
• Verify that a competent person measures and records the thermal conditions at frequent intervals [2].
• Ensure availability of appropriate PPE for extreme temperatures (e.g., insulated clothing, cooling vests) [3].
• Ensure proper communication methods are in place.

B. Equipment Specific

• Engine Oil: Use engine oil designed for hot or cold climates 1, 2.
• Hydraulic Oil: Use hydraulic oil designed for hot or cold climates 1, 2.
• Fuel Oil/Diesel Fuel: Use fuel designed for hot or cold climates 1, 2.
• Coolant Mixture: Verify engine coolant mixture is sufficient for expected temperatures, considering wind chill in cold conditions 1, 2. Mix coolant to a protection temperature of 5C degrees (9F degrees) lower than the machine will experience during operation, storage or transport [4].
• Battery: Ensure the battery is fully charged 1, 2.

II. During Operation Checks

A. General

• Monitor personnel for signs of heat or cold stress. Ensure adequate breaks and hydration/warming opportunities 10, 13.
• Ensure work-rest regimen for heat, the work-warming regimen for cold and other advice found in the ACGIH publication entitled '2016 Threshold Limit Values for Chemical Substances and Physical Agents and Biological Exposure Indices' are followed [2].

B. Equipment Specific

• Gauges: Keep a close watch on the gauge cluster for warning icons during operation 1, 2.
• Engine Temperature: Monitor engine temperature gauge to avoid overheating [5].
• Air Cleaner: Check the engine air cleaner elements frequently in sandy or dusty conditions [5].
• Radiator/Oil Cooler: Clean radiator, oil cooler, and debris screen often to prevent damage or overheating [5].
• Belts: Keep all belts properly tensioned [5].
• Battery Terminals: Keep battery terminals free of ice and snow in cold conditions [4].

III. Post-Operation Checks

• Coolant Level: Check engine coolant level using the multi-display [6].
• Oil Pressure: Check engine oil pressure using the multi-display [6].
• Fuel Level: Fully refill with fuel, but do not overfill [6].
• Leaks: Check for any oil or coolant leakage [6].
• Cleaning: Thoroughly wash the machine daily, especially in salty or humid climates, and coat bare surfaces with oil-based lubricant to prevent corrosion [5].
• Hardware: Frequently check all mounting hardware for proper tightness, especially in salty climates [5].

IV. Corrective Actions

• If the machine becomes overheated, idle the machine to help cool the engine, turn engine "OFF" and check coolant level. After filling to proper level the machine continues to over heat, stop engine, allow to cool, drain and flush entire cooling system and refill with the proper mixture of fresh, clean coolant [5].
• If warnings of engine coolant and engine oil pressure are displayed, move the machine to a safe place and stop the engine. And then repair it according to applicable procedure in Chapter 4 "INSPECTION & MAINTENANCE CHART" [6].
• If leakage and damage are found, repair it immediately according to applicable procedure in Chapter 4 "INSPECTION & MAINTENANCE CHART" [6].
