Tools

Other engineering controls that can improve shipyard ergonomics involve optimizing the tools that employees use on a regular basis. These improvements include the use of power tools, adding extension handles to tools, the use of low-vibration tools, and the use of tool balancers.

Power Tools

Power tools that are made of lightweight, durable materials can reduce the hand and arm fatigue caused by holding a tool for several hours. Select lighter tools with less vibration.

Tool Extension Handles

Adding long extension handles to handheld tools can enable workers to work standing instead of in awkward postures, such as kneeling or crouching. Extension handles can be attached to many types of handheld tools, including needle guns, buffing wheels, and grinders. The handle and tool can both be attached to wheels or channel sliding plates to further reduce the weight and force needed to operate the tool. In some cases, extension handles may reduce the vibration transmitted to the worker's hands and arms.

Take precautions not to alter tools in a way that violates the National Electrical Code (NEC) or OSHA standards. Be aware that an altering a tool may pose new hazards, and may also void the manufacturer's warranty.
