Inspecting Tools for Wear, Damage, and Cracks
Before any offshore task begins, tools must be inspected for defects. Damaged tools are one of the leading causes of hand injuries, equipment damage, and unexpected failures.
A proper inspection routine is essential for safe mechanical work.
1. General Inspection Principles
Every tool should be checked for:
- Structural integrity
- Cracks or fractures
- Deformation or bending
- Rust or corrosion
- Loose or missing components
The inspection should take only seconds but can prevent serious incidents.
2. Visual Inspection Checklist
• Cracks and Fractures
Look especially around:
- Handles
- Jaws
- Striking surfaces
- Pivot points
Hairline cracks can rapidly worsen under load.
• Deformation
Signs include:
- Bent handles
- Twisted jaws
- Rounded edges
- Mushroomed hammer heads
Deformed tools must be removed from service immediately.
• Corrosion and Rust
Surface rust is manageable, but:
- Deep rust = weakened structure
- Corrosion pits can become fracture points
Offshore environments accelerate corrosion — frequent checks are essential.
• Loose Components
Check:
- Rivets
- Joints
- Bolts
- Socket retention
Loose parts can fail during use and cause injury.
3. Specialized Tool Checks
• Wrenches
Check for rounding of jaws and proper alignment.
• Screwdrivers
Inspect tips for damage or wear.
• Pliers
Ensure pivot points are smooth and not loose.
• Impact Tools
Inspect for mushrooming, cracks, and loose heads.
4. When to Tag Out a Tool
A tool must be immediately removed from service if any of the following are found:
- Cracks
- Severe rust
- Bent components
- Mushrooming on impact tools
- Excessive wear
- Loose fittings
- Damaged or missing parts
Tag-Out Procedure
- Stop work safely
- Attach a “Do Not Use” tag
- Notify supervisor
- Remove tool to maintenance area
5. Importance of Inspection Offshore
Offshore installations present:
- High humidity
- Saltwater exposure
- Constant movement
- Heavy mechanical work
This environment accelerates tool degradation. Daily inspection is not optional — it is required.
Key Takeaways
- Inspect tools before every use
- Look for cracks, bends, rust, and wear
- Tag out any tool with defects
- Proper inspection prevents accidents and rework
