Hold pliers firmly but not excessively tight. Position yourself so you have good balance and leverage.

• Maximizing control and minimizing strain or slips during use.
• Applying too much force can cause the pliers to slip, potentially injuring your hand or damaging the workpiece.
• Use two hands for extra leverage on tough jobs, or consider a tool with longer handles if available.
• Technique – Firm Grip, Balanced Stance.
• Risk Mitigated – Slipping, Strain.

Step 5. Cut Away From Your Body

When using cutting pliers, position the jaws so that any cut-off pieces will fly away from you and others. Always ensure the cutting action is directed away from your face and hands.

• Preventing injury from flying debris or sharp edges.
• Small pieces of wire or plastic can travel at high speeds after being cut.
• Consider using a hand to cup around the cutting area to contain small pieces, in addition to eye protection.
• Cutting Direction – Away from Body.
• Risk Mitigated – Flying Debris Injury.

Essential Safety Gear and Pre-Checks

Before you even pick up a pair of pliers, taking a moment to prepare your workspace and yourself can prevent many common accidents. Safety isn’t just about how you use the tool, but also the environment you’re working in.

The most fundamental piece of safety gear for any task involving pliers, especially cutting, is eye protection. Small pieces of wire, metal, or plastic can become projectiles, causing serious eye damage.

Beyond eye protection, consider gloves for tasks that might involve sharp edges or rough materials. Good quality work gloves can improve grip and protect your hands from nicks and scrapes.

Before cutting a piece of old fence wire, always put on safety glasses to protect against flying metal fragments.

Skipping safety glasses for ‘quick’ tasks or assuming a task is too minor to warrant protection.

Choosing and Inspecting the Right Pliers

One of the most common causes of accidents and damaged tools is using the wrong type of pliers for the task at hand. Pliers come in many forms, each designed for specific functions like gripping, cutting, bending, or holding.

For instance, slip-joint pliers are versatile for gripping various sizes, while diagonal cutters are specifically for cutting wire. Lineman’s pliers offer strong gripping and cutting capabilities for electrical work, and long-nose pliers are ideal for reaching into tight spaces.

Equally important is a quick inspection of your pliers before each use. Look for any signs of wear or damage: chipped or bent jaws, a loose pivot joint, or compromised handle insulation.

If you need to grip a small, delicate wire, reach for needle-nose pliers, not heavy-duty slip-joint pliers.

Using pliers that are too small or too large for the job, or using pliers with worn, chipped, or misaligned jaws.

Safe Gripping and Cutting Techniques

Proper technique is at the heart of safe pliers use. How you hold the tool, apply force, and position your body all contribute to a secure and efficient operation.

When gripping an object, ensure the jaws of the pliers are fully engaged and parallel to the surface for maximum contact. This prevents the object from slipping and reduces the chance of rounding off corners.

For cutting tasks, always position the pliers so that the cutting action is directed away from your body, face, and any bystanders. This minimizes the risk of injury from flying debris.

When cutting a wire, position the pliers so the cut-off piece will fall away from you.

Over-gripping or applying excessive force, which can cause the pliers to slip or damage the workpiece.

• Keep your wrists straight and avoid bending them at awkward angles to prevent strain.
• Use the leverage of the pliers; don’t try to overpower the tool with brute force.
• For very tough cuts, consider using a larger cutting tool designed for higher capacity, rather than straining small.

Common Pliers Misuses to Avoid

Pliers are incredibly versatile, but they are not universal tools. Misusing pliers can lead to serious injury, damage to the tool itself, or harm to the workpiece.

One of the most frequent misuses is treating pliers as a hammer. The hardened jaws are not meant for impact and can chip, sending sharp fragments flying.

Another critical misuse involves electrical work. Unless your pliers are specifically rated and insulated for live electrical circuits, never use them on energized wires.

Never use a pair of pliers as a hammer to tap something into place; the jaws can chip and create dangerous projectiles.

Using pliers for tasks they were not designed for, such as hammering, prying, or as a substitute for a wrench.

Misuse	Why It’s Dangerous/Harmful	Correct Tool to Use Instead
Using as a Hammer.	Can chip jaws, create flying debris, damage workpiece.	Hammer or Mallet.
Using as a Wrench.	Rounds off fasteners, damages plier jaws, poor grip.	Open-end, Box-end, or Adjustable Wrench.
Cutting Hardened Wire.	Dulls or chips cutting edges, can break pliers.	Bolt Cutters or Pliers specifically rated for hardened wire.
Working on Live Wires (uninsulated).	Risk of electric shock, arc flash, serious injury.	Insulated Pliers (rated for voltage) AND De-energized Circuit.
