Ergo Wisdom 07: Minimizing Contact Force.

"Minimizing contact force" is an essential ergonomic principle aimed at reducing the physical strain placed on the body during tasks that involve gripping, pressing, or applying force to objects. By reducing the amount of contact force required for various activities, you can help prevent discomfort, fatigue, and long-term injuries, particularly in the hands, wrists, arms, and shoulders.

Here’s how you can implement it for a more comfortable and productive work experience.

Ergonomically Tools and Equipment

Select tools and equipment that are designed with ergonomics in mind.
Ergonomic tools should have handles that are easy to grip, with padding or contours that reduce the need for excessive force.
Tools should also be appropriately sized for the user's hands to ensure a comfortable grip.

Encourage Light Touch and Precision

For tasks like typing or using a mouse, encourage employees to use a light touch rather than applying excessive force.
High-contact-force actions such as hard key presses or vigorous mouse movements can lead to muscle fatigue and stress.
Using devices designed for easy operation can help reduce the force needed to complete tasks.

Promote Proper Posture

Working at a desk, sitting with your elbows at a 90-degree angle and your wrists in a neutral position helps avoid unnecessary strain.
Avoiding awkward wrist angles reduces the force needed to manipulate tools or devices.

Power-Assisted Tools

Tasks like stapling documents, hole-punching, or even assembling large volumes of paperwork often require repetitive gripping and pressing, which can lead to hand and wrist strain.
Using power-assisted tools designed for these tasks can significantly reduce physical effort and improve efficiency.

Training awareness

Educate other colleagues on the importance of minimizing contact force and how it can help prevent injury and improve comfort.
Teach them to recognize when they are using too much force and encourage them to adjust their technique, posture, or equipment to reduce strain.
Proper training can also highlight the importance of taking regular breaks and stretching to reduce muscle fatigue.
