Why is it recommended to keep the keyboard and mouse close together?
Press to flip
To avoid reaching too far, which can cause shoulder and arm strain.
What adjustments should be considered for a monitor to reduce eye strain?
Regularly clean the screen, adjust brightness and contrast, and consider using blue light filters.
What ergonomic feature should tools promote to reduce strain?
Tools should promote neutral wrist positions and use energy-saving mechanisms (prefer second-class levers over third-class levers).
Describe the proper lifting technique in manual material handling.
Bend the knees, not the hips; keep the back straight; hold objects close to the body to reduce stress.
What are the factors to consider for monitor selection and placement in office ergonomics?
Viewing distance, angle, time, and clarity.
How should armrests on a chair be configured for optimal ergonomics?
Armrests should be removable if they obstruct proper distance to the keyboard/mouse, stable, and allow for swivel to reduce torso twist.
What should be avoided when lifting heavy objects alone?
Avoid twisting and lifting heavy objects alone.
What is the ideal posture for using a keyboard and mouse?
Shoulders relaxed, elbows at a 90° angle, and wrists in a neutral position.
What are the ideal conditions for pushing and pulling tasks?
Pushing/pulling with two hands, on flat surfaces, and with proper body angles (waist level for pushing, thigh level for pulling).
What issues can arise from monitors placed too close or too far from the user?
Too close can cause eye strain and awkward neck posture (hyper/hypo-extension), while too far can cause eye strain and forward-leaning posture.
What are some guidelines for using sit-stand stations?
Alternate sitting, standing, and moving (e.g., 20 minutes sitting, 8 minutes standing, 2 minutes moving).
How should the top of the monitor be positioned relative to the user's eyes?
The top of the monitor should be at or slightly below eye level.
Why is it important to have regular breaks when using a monitor for prolonged periods?
Regular breaks help to rest the eyes and stretch, reducing eye strain and muscle fatigue.
Why is it important to use carts or elevators when carrying heavy loads over long distances?
To reduce the stress on the back and use bigger muscles, keeping the load close to the body. Using tools like carts or elevators helps distribute the weight and alleviates physical strain.
Why should the user consider an external keyboard when using a laptop?
Laptop keyboards might not fit well with the recommended ergonomic posture, leading to discomfort or strain.
