Pliers, Cutters, and Grip Tools

Pliers and cutters are some of the most versatile hand tools used offshore. They allow gripping, twisting, cutting, and holding components — but improper use can lead to crushed fingers, cutting injuries, and damaged equipment.

Understanding each tool’s purpose and limitations is essential for safe operation.

1. Types of Pliers and Their Uses

• Combination Pliers

General-purpose tool used for gripping, bending, and cutting soft wire.

• Long Nose (Needle Nose) Pliers

Used for reaching into tight spaces or holding small components.

Not designed for heavy torque.

• Slip-Joint Pliers

Adjustable jaw width for gripping different sized objects.

• Locking Pliers (Vise-Grips)

Used for strong clamping force — hold objects in place, free frozen bolts, or keep tension on a component.

Locking pliers must never replace correct wrench use.

2. Cutters

• Diagonal Cutters

Used for cutting wire, cable ties, and soft materials.

• End Cutters

Used for cutting flush to a surface.

• Heavy-Duty Bolt Cutters

Used for padlocks, heavy wire, and metal rods.

Require full PPE and line-of-fire awareness.

3. Safe Use Techniques

Grip Safety

• Keep fingers away from pivot points
• Maintain a firm but controlled grip
• Ensure the tool is fully seated before applying pressure

Cutting Safety

• Direct the cutting edge away from the body
• Secure the material being cut
• Use the correct cutter — forcing a tool can cause breakage

4. Common Hazards

• Pinch Points

Hands and fingers can get caught between handles if grip slips.

• Flying Cut Pieces

Cut wire or metal can become a projectile.

• Crushing Injuries

Locking pliers can snap closed unexpectedly.

• Tool Failure from Overload

Cutting materials beyond tool rating can crack jaws.

5. Tool Limitations

These tools are not to be used for:

• High-torque twisting
• Bending thick pipes
• As a substitute for wrenches
• Cutting hardened steel unless rated for it

Misuse leads to tool breakage and injury.

6. PPE Requirements

• Safety glasses
• Impact-resistant gloves
• Face shield when using bolt cutters
• Long sleeves for protection from flying fragments

Key Takeaways

• Choose the right plier/cutter for the job
• Maintain stable grip and body positioning
• Keep fingers out of pinch points
• Never overload or misuse cutting tools
• PPE prevents severe injuries
