Preventing Ergonomic Injuries in Utility Vegetation Management

Preventing Ergonomic Injuries in Utility Vegetation Management

By M.K. Youngblood, Safety Manager and Tribal Liaison, ACRT Pacific

Utility vegetation management is a dangerous industry, so preventing injuries in any way possible is paramount. One of the easiest ways we can prevent injuries in the workplace is by using proper ergonomic practices.

The Occupational Safety and Health Association (OSHA) defines ergonomics as the science of designing job tasks to physically fit the worker rather than forcing the worker to make their body fit the job tasks. Since ergonomic injuries are one of the leading work-related hazards, it is important to understand how ergonomics affect job tasks and how to properly complete said tasks. Failure to do so can result in musculoskeletal disorders such as sprains, strains, tendonitis, and lower back injuries.

Practices that Lead to Ergonomic Injuries

There are various ergonomic practices that, when done incorrectly, can lead to injuries. Joints, muscles, tendons, and ligaments are the most susceptible to injury, so it is important to understand how each ergonomic practice can affect these parts of the body.

Heavy, Frequent, and Awkward Lifting. When you bend down to pick up something heavy, it puts great stress on the lower spine, causing pain and muscle fatigue. Additionally, if you carry something and have it resting on one shoulder it can put uneven pressure on one side of the spine which can also cause muscle and back pain.

Repetitive Tasks. When a task is repeated constantly, damage to the muscles, nerves, and tendons can occur. Overuse is a common reason people experience muscle pain, nerve pain, and fatigue.

Awkward Hand Grip. Holding tools incorrectly can put too much pressure and strain on one part of the hand. The excess pressure can cause stress and injury to the tendons and muscles in the hand.

Postures Using Excessive Force. Using a high amount of force creates excessive strain on muscles and tendons, potentially causing strains, sprains, and tears.

Hand-Intensive Work. Overworking the hands is a common occurrence in various fields. Repetitive work on the hands can cause damage to joints, especially when you don’t allow for adequate rest.

How to Prevent Common Injuries?

It is possible to prevent common injuries caused by ergonomic hazards. These precautions include:

• Considering the overall weight and configuration of lifted items
• Stopping to get additional assistance when possible
• Using ergonomically designed tools with hand grips
• Wearing gloves for repetitive tasks
• Switching hands periodically
• Using proper tools and keeping them in good condition
• Stretching to warm up before work and periodically throughout the workday
• Getting adequate rest and maintaining proper hydration
• Ensuring correct posture that uses the legs with a straight back, with no twisting and no bending

Neutral Postures to Prevent Ergonomic Injuries

Making sure your body is in the proper position for certain activities can largely reduce your risk of musculoskeletal injury. Neutral postures align and balance the body and joints to reduce the amount of stress applied to muscles, tendons, nerves, and bones while sitting or standing. Awkward postures are the opposite of neutral postures, moving toward a dangerous range of motion, and are responsible for musculoskeletal injuries.

The Power Zone

The power zone is where you want to be when lifting heavy objects. The zone is close to the body, between the mid-thigh and mid-chest. This is the position in which the arms and back can pick up the most amount of weight with the least amount of effort or strain.

Making sure you are using neutral positions to avoid ergonomic hazards is extremely important in utility vegetation management. Foresters and linemen have to get to some difficult places and may be required to lift heavy equipment or move heavy objects, all of which may strain the musculoskeletal system. Knowing how to position your body during these activities properly can prevent a painful injury from occurring.
