• Eye Injuries: Flying debris from hammering, chiseling, or grinding can cause eye injuries if proper eye protection is not worn.

Key Hazards Associated with Hand Tools

The risks associated with hand tools can be broadly categorized into several key areas, each requiring specific preventative measures.

1. Impact Tools: The Force of the Blow

Impact tools, such as hammers, chisels, and punches, are designed to deliver force to a specific point. However, this concentrated force can also be a source of danger.

• Mushroomed Heads: Repeated impact can cause the heads of hammers and chisels to mushroom or spread. These mushroomed edges can chip off and become dangerous projectiles. Regular inspection and dressing of tool heads are essential.
• Slipping: If the tool slips during use, the user can strike their hand or another body part. A firm grip, proper positioning, and using appropriate striking surfaces can help prevent slippage.
• Flying Debris: Striking metal on metal can generate flying debris. Wearing safety glasses or a face shield is crucial to protect the eyes.
• Handle Issues: Loose or damaged handles can cause the tool to become uncontrollable, leading to misdirected blows and potential injury. Regularly inspect handles for cracks, splinters, or looseness.

2. Cutting Tools: Precision and Peril

Cutting tools, including knives, saws, and axes, are designed to create a separation of materials. Their sharp edges, while necessary for their function, pose a significant risk of cuts and lacerations.

• Sharpness: A dull cutting tool requires more force to use, increasing the risk of slippage and loss of control. Keeping cutting tools sharp is crucial, but sharpening itself must be done with care.
• Guarding: Many cutting tools lack adequate guarding, leaving the user's hands and fingers vulnerable. When possible, use tools with built-in guards or wear appropriate hand protection.
• Direction of Cut: Always cut away from the body to avoid accidentally drawing the tool towards yourself.
• Secure Grip: Maintain a firm grip on the tool and the workpiece to prevent slippage. Use clamps or vises to secure the workpiece when possible.
• Sheathed Storage: Store cutting tools in sheaths or protective cases to prevent accidental cuts when not in use.

3. Gripping Tools: The Power of Leverage

Gripping tools, such as pliers, wrenches, and vises, are used to hold, tighten, or loosen objects. The leverage they provide can also create hazards.

• Slipping: If the tool slips off the workpiece, the user can lose their balance or strike their hand against nearby objects. Using the correct size tool and ensuring a tight grip can help prevent slippage.
• Overexertion: Applying excessive force can cause the tool or the workpiece to break, leading to injury. Use the appropriate amount of force for the task and avoid using extensions or cheater bars to increase leverage.
• Damaged Jaws: Worn or damaged jaws can cause the tool to slip or fail, increasing the risk of injury. Regularly inspect the jaws of gripping tools and replace them if necessary.
• Pinching: Fingers can be pinched between the handles of pliers or wrenches. Use caution when closing the tool and avoid placing your fingers in the pinch point.

4. Striking Tools: Direct Application of Force

Striking tools, such as hammers and mallets, are used to apply direct force to another object. The force they deliver can be a source of injury if not used correctly.

• Misdirected Blows: Missing the target and striking your hand or another body part is a common hazard with striking tools. Maintain a clear line of sight to the target and use a controlled swing.
• Flying Fragments: Striking hardened materials can cause fragments to chip off and become projectiles. Wear safety glasses or a face shield to protect the eyes.
• Rebound: Striking a surface with too much force can cause the tool to rebound, potentially striking the user. Use the appropriate amount of force for the task and maintain a firm grip on the tool.
• Handle Failure: Loose or broken handles can cause the tool to become uncontrollable, leading to misdirected blows and potential injury. Regularly inspect handles for cracks, splinters, or looseness.

5. Screwdrivers and Awls: Puncture and Slip Risks

Screwdrivers and awls are used for driving screws and making pilot holes, respectively. While seemingly simple, these tools pose unique hazards.

• Slipping: If the screwdriver slips out of the screw head, the user can stab their hand or another body part. Use the correct size and type of screwdriver for the screw and apply steady pressure.
• Punctures: Awls can easily puncture the skin if misused or if the user slips. Use caution when applying pressure and avoid placing your hand in the path of the tool.
• Using as a Chisel: Screwdrivers are not designed to be used as chisels and can break or shatter if struck with a hammer. Use the correct tool for the job.
• Damaged Tips: Worn or damaged screwdriver tips can cause the tool to slip and damage the screw head. Regularly inspect screwdriver tips and replace them if necessary.
