Workplace Injury Statistics (2012)

Approximately $4$ million workplace injuries, $7$ days of lost work time, and $5$ thousand fatalities were reported, with $9\%$ of injuries caused by hand tools.

Complacency

An unsafe work behavior where a worker confuses their experience with safety, often thinking, "I’ve done this a hundred times."

The 3 “M”s of Tool Injuries

The three key reasons people are injured by hand tools: Modification, Improper Maintenance, and Misuse.

Modification

Changing a tool's structure or design, or adding attachments not intended for that tool.

Improper Maintenance

Failing to keep a tool clean and in good condition, or continuing to use a broken or cracked tool.

Misuse

Using the wrong tool for a job or using the right tool in the wrong way.

Class E Hard Hat

A head protection classification specifically for Electrical protection.

Class G Hard Hat

A head protection classification for General protection.

Class C Hard Hat

A head protection classification for Conductive protection.

Torque Wrench Types

Designed for specific degrees of accuracy; includes Bending Beam, Click-Type, Dial, and Electronic models.

The Four Types of Sockets

Hand, Power, Impact, and Special Application.

Hand Sockets

Tools with a harder heat treat that should never be used on impact drills, as they can result in critical injury.

Impact Sockets

Heavy walled tools heat treated to a lesser hardness to avoid cracking or splitting under repetitive impact blows.

Dropped Objects

The $4$th highest cause of death in the workplace, which necessitates the use of engineered tethering tool systems when working overhead.

Chisel Redressing

The process of sharpening or maintaining a chisel head using a file; power tools or bench grinders should never be used for this task.

Starter Punch

A specific punch used to create the inertia required to start a seized roll pin.

Center Punch

A tool that should never be used to drive roll pins because it will cause the pin to expand or freeze in the hole.

Screwdriver

The most commonly used and misused hand tool, intended only for turning fasteners.

Pliers

Tools available in roughly $80$ different styles used for cutting, stripping, bending, and holding.

Electric Shock Protection

Safety provided by tools made from composite materials; plastic, rubber, or vinyl coatings do not necessarily provide insulation.

Ergonomics

Tool features designed to fit the hand, reduce static muscle fatigue, mitigate contact stress, and reduce vibrations to the hand and arm.
