Preventing common injuries on walking-working surfaces
Sprains and strains
Sprains and strains are two different injuries but have common symptoms and treatment. A sprain is a torn or stretched ligament between two bones. For example, if an employee complains about pain in their ankle area, it may be a sprain. A strain is a stretch or tears to muscles or tendons that connect to bones. If a worker complains about pain in their lower back area, it may be a strain.
On average, sprains take longer to heal than strains do. Depending on the severity of the injury, a strain can take one week to heal, while a sprain may take from two to four weeks to heal. Knowing this difference can help employers understand an injured worker’s recovery time.
Walking-working surfaces
Workers can be at risk for sprains and strains on walking-working surfaces on jobsites. Injuries often occur while lifting something or stepping down from a vehicle or equipment. Knowing this, project leaders should consider these best practices:
- Ensure that all equipment, like cranes, forklifts, and vehicles, has an intermediate step. This will prevent workers from over-reaching while stepping off equipment or down from a vehicle.
- Verify that steps on equipment and running boards on vehicles aren’t worn, broken, or defective. Use ladders or mobile stairs to assist workers with accessing and egressing equipment.
- Use mechanical means when lifting anything weighing more than 50 pounds. Often, workers may become victims of human error traps, thinking that other workers will look down on them or make fun of them for using a forklift or a crane to lift something heavy. Having a universally applied safety policy in place, and requiring workers to use mechanical means, may prevent this.
- Consider better options before using team lifting. Often, one worker will over lift one side too high, causing the load to distribute unevenly to the other worker. This uneven shift of weight can injure the other worker.
Have workers spend time warming up their muscles during the safety planning meeting. This can help them avoid sprains and strains.
Stretch and flex
Having a voluntary stretch and flex program is an industry best practice. This can be a fun exercise to do with your workers while talking about the safety plan for the day. Be flexible with the program and how workers can participate in it, realizing some workers may have physical limitations, disabilities, or injuries that prevent them from participating altogether. Select stretch and flex exercises that can be performed from a seated position too.
A stretch and flex program aims to prevent workers from suddenly jumping into physical labor activities, from a rested state, without first warming up their muscles. A quick warm-up will ready workers’ bodies for increased physical demand. Workers often refer to this as “getting the blood flowing” or “warming up the juices.” Performing stretch and flex exercises can reduce workers’ risks for sprain or strain injuries over walking-working surfaces.
