Safety Is/Isn’t Easy? by Joseph J. Werbicki, M.S., CSP

As with any other premise, it depends. Where behaviors are involved, anything can happen, given the need for brain, eye and reflex coordination.

Think about playing a slot machine, specifically, one on which you can stop the reels. You have a situation where the eyes see, the brain reacts, and your reflexes tell you when to (try to) stop the reels. I say “try to” because you all know that the machine will fight you, and, more often than not, keep the other reels moving for a time after the first one has stopped.

Trouble is, you can’t always depend on your reflexes to get the job done. You must use your eyes and your brain as well as your reflexes to improve your odds of avoiding accidents.

Here are some possible accident prevention approaches:

  • Safety by design (integrating safety with machine functions)
  • On-the-job training
  • Job Safety (Hazard) Analyses to identify all safety hazards of a job and to prescribe the best ways to abate them
  • Awareness – attention to everything around us
  • See – Think – Act. The eyes see; the brain interprets and directs physical response
  • Hazard identification and abatement. You can’t fix what you don’t identify. Once identified, fix it
  • Guarding – barriers separate us from physical hazards
  • Strong enforceable safety policies – what people need to know, along with consequences, both hazard and discipline-wise
  • Signage – constant reminders of safety issues
  • Mentoring – one-on-one guidance when human performance is an issue
  • Mutual concern for each other’s safety
  • Putting safety on a par with productivity – a strong signal that workers are valued
  • Safety Culture – this is what we do

 

Safety culture revolves around the attitudes surrounding the role of safety in an organization, and consists of a number of elements:

  • Accident and near-miss reporting
  • Correcting what you can correct yourself
  • Pointing out hazards
  • Mentoring
  • Everyone is involved in safety
  • Safety is an integral part of each job
  • Effective accident investigation and implementation of corrective action

 

Sometime you can’t really come up with a corrective action, because it appears that only human factors might be involved. As an example, suppose someone trips over the curbing in the parking lot, and is injured. What corrective action might be considered?

  • There is no OSHA policy regarding curb height requirements
  • However, Federal Highway guidelines prescribe heights of 4 – 8 inches, with the typical height of 6 inches
  • Does the curbing height vary over its length?
    • Typical riser heights on stairs are 6 – 9.5 inches
    • OSHA prescribes that stair risers “shall be uniform within each flight of stairs to within ± ¼ inch”
  • The curbing has been there forever, with no tripping incidents reported
  • Is there sufficient contrast between the roadway and the sidewalk colors?
  • Place signs reminding people to walk carefully?
  • Publicize accident to raise awareness?
  • If all else fails to identify a root cause, we may have to accept the fact that the cause is “undetermined”

 

“Told employee to be more careful” might fill in the blanks on an accident investigation report, but feedback and information sharing are needed to raise awareness to the hazard(s), along with attempting to developing procedures to avoid recurrences.

A challenging part of safety is getting buy-in. Maybe we simply need to emphasize “going home safe” in the back of our minds.

Lift Easy by Joseph J. Werbicki, M.S., CSP

Nov 17, 2017

According to Travelers Insurance, the most common cause of accidents and injuries is Material Handling.  It wouldn’t be much of a stretch to believe that many of these could very well be back injuries resulting from overexertion as the result of manual lifting.

Many times we simply don’t think before we lift something, putting ourselves at risk for an overexertion injury.

The human back is actually fragile, depending on its muscles for protection from injury.  Once injured, a back is at greater risk for future injury if we fail to protect it by practicing good lifting technique.

How can we reduce such overexertion injuries, especially those involving the back?  Some effective approaches include:

  • Training employees in safe lifting techniques
  • Highlighting the dangers of lifting improperly
  • Setting single-person lifting limits
  • Constant reminders and supervisory oversight
  • Stretching exercises at the start of a work shift
  • Using lifting aids whenever possible

 

NIOSH guidelines on manual lifting were prompted by Department of Labor and National Safety Council data, which indicated that back injuries and overexertion account for 20 – 30% of all workplace injuries.  Liberty Mutual data(1) indicate that injuries caused by overexertion account for over 30% of all non-fatal work-related injuries.

Given this information, it’s not unreasonable to expect that many of us might be candidates for a back injury if we don’t use effective lifting techniques, both on and off the job.

NIOSH developed the “Lifting Equation”(2) that allows us to calculate the maximum safe weight (Recommended Weight Limit, or, RWL) for any single-person manual lifting activity performed over the course of an 8-hour shift.  Lifting any weight greater than the RWL for an extended time period can increase the risk of injury.

The NIOSH recommended weight limit for a single-person two-handed lift is 51pounds, under the best of conditions.  A number of factors can contribute to lowering this weight limit, i.e.:

  • How far away from the body is the object carried?
  • How high off the floor is the object being carried?
  • The height difference between the object’s origin and its destination?
  • How much the body is twisted to accomplish the task?
  • How many lifts are to be completed in a given period of time?
  • How well can the object be grasped?

 

The Lifting Equation can be used to calculate the safe weight limit for any given repetitive lifting operation, or, we can simply keep the following precautions in mind, when lifting requirements vary over a workday.

  • Designate a weight limit beyond which tasks are designated as 2-person lifts
  • Get a good grip on the load
  • Keep the object as close to the body as possible (reaching out puts added stress on the back)
  • Carry the object with the elbows as close to 90-degrees as possible
  • Don’t twist the body while carrying the object

 

In addition, the following can help to reduce the stresses involved in manual lifting:

  • Use hoists, conveyer tables or lift trucks
  • Get help to lift heavy or cumbersome loads
  • Minimize lifting motions below the knees and above the shoulders
  • Store most-used items in the power zone, between standing knuckle height and shoulder height
  • Most importantly, always use good lifting technique

 

Good lifting technique doesn’t come naturally and takes practice in order make it a part of any lifting routine.  The critical component, “lift with your legs, not with your back” plays an important role when you lift. It’s your muscles that provide the strength for lifting, and your legs contain some of the strongest muscles in the body, far stronger than back muscles.

The following are suggestions that can help you to lift while minimizing the risk to your back.

  • Check the weight of the object to determine if you can handle it. Try to lift one edge before grabbing the object.  Many people find objects weighing less than 51 pounds to be too heavy for them. If in doubt, get help.
  • Make sure that there is a clear path to your destination.
  • If the object is on the floor or on a low surface, I have found the following to be effective:
    • Take a shoulder-wide stance close to and directly in front of the object to be lifted.
    • Bend your knees.
    • Look straight ahead, and lean slightly backward, as if you were preparing to sit down (this will serve to straighten your back).
    • Keep your back straight (you want to lift with your legs, not with your back).
    • Get a good grip (opposite corners of a box). Punch out finger holes on boxes that can’t be easily gripped.
    • Lift by straightening your legs in a smooth movement.
  • Never twist your body while holding a load. Turn your whole body.

 

It takes practice to make safe lifting a habit.  With practice, these suggestions can help reduce the risk of a common injury.
