Pre-Start Walk-Around Inspection
Purpose of the Walk-Around
The pre-start walk-around inspection is the single most important safety task an operator performs before starting any piece of heavy equipment. The purpose is to identify defects, leaks, loose components, and safety issues before operation. Every machine must be inspected at the start of each shift - no exceptions.
Walk-Around Sequence
Begin by approaching the machine from a distance and looking underneath for fluid puddles or debris. Then walk completely around the machine, checking each side methodically. Look for cracked or damaged hoses, loose bolts, missing guards, damaged steps or handholds, and any signs of structural damage.
What to Look For
During the walk-around, check tires or tracks for damage, proper inflation, or correct tension. Inspect pins and linkages for wear or missing retainers. Verify that guards and shields are in place. Check all lights, mirrors, and cameras for damage or obstruction. Confirm the back-up alarm functions by having someone listen while the machine is started.
Never Skip the Walk-Around
Many equipment incidents could have been prevented by a thorough pre-start inspection. A missing pin, cracked hose, or low fluid level caught early can prevent a catastrophic failure during operation.
The pre-start walk-around inspection identifies defects, leaks, loose components, and safety issues before operation. It must be performed at the start of every shift without exception.
