What is Ergonomics? “Ergonomics is an applied science concerned with the design of workplaces, tools, and tasks that match the physiological, anatomical, and psychological characteristics and capabilities of the worker.” Vern Putz-Anderson “The Goal of ergonomics is to ‘fit the job to the person,’ rather than making the person fit the job.” Ergotech “If it hurts when you are doing something, don’t do it.” Bill Black The term ergonomics comes from the Greek words ‘ergo’ meaning ‘work’ and ‘nomos’ meaning ‘law(s)’. So, basically ergonomics means the ‘laws/principles of human work.’ Ergonomics as a field has to do with designing work spaces that promote optimal human performance. For a long time, system design, whether a machine or a manufacturing plant layout, was focused solely on the product. In recent times we have recognized the role of the human as a part of the system – and thus the importance of integrating human dimensions and capabilities into the overall design process.

Why do we care about Ergonomics? OSHA Employee Turnover ADA Quality Injured Workers Insurance Costs Whether we want to believe it or not, ergonomic design can have a significant impact on our businesses. Poor ergonomic design in the workplace can lead to costly injuries. Often these jobs are undesirable, leading to high turnover and absenteeism. Also, ergonomic deficiencies can impact productivity and quality – fatigued or uncomfortable workers make more mistakes and/or take shortcuts. Additionally, while there is no OSHA ergonomic standard, companies with significant ergonomic injuries can still be cited under the general duty clause (5a1). Increased Productivity Absenteeism

Ergonomic Injuries - WMSDs Year in and year out, ergonomically related injuries (often referred to as work-related musculoskeletal disorders – WMSDs) make up a significant portion of serious days away injuries. In 2010, Overexertion + Repetitive Motion injuries made up 32% of all days away injuries. Overexertion injuries are often associated with strains, sprains and tears resulting from lifting, pushing, pulling, carrying, reaching, etc. activities. Overexertion is self-descriptive – it means injuries resulting from over-stressing the body to accomplish a job task…a sign of a sub-optimal ergonomic design. [Chart based on data from 2010 BLS Annual Summary Data]

More than simple workers’ comp costs – days away injuries impact efficiency and quality as workers are forced to be shifted around, do multiple jobs…or if temp workers are hired, you have a loss of experience (not to mention placing a novice worker in an injury prone job). Liberty Mutual’s 2010 Workplace Safety Index ranks overexertion injuries as the #1 most costly injury in the US – at $13.4 Billion in direct costs to employers (25% of all injury costs).

OSHA and Ergonomics OSHA can and will cite ergonomic hazards under the “5(a)(1)” General Duty Clause, if: An ergonomic hazard exists, The hazard is recognized, The hazard is causing, or likely to cause, a serious injury, And if a feasible means exists to reduce the hazard Patrick Kapust with OSHA’s Directorate of Enforcement Programs told attendees at the recent American Society of Safety Engineers’ (ASSE) Safety 2009 conference that the agency has issued 19 General Duty Clause citations for ergonomics since 2002. During the same time period, OSHA conducted 4,500 ergonomic inspections and issued 640 hazard alert letters on ergonomics. The companies that received those letters can expect follow-up from OSHA. Also at the ASSE conference, OSHA administrator Jordan Barab said ergonomics was “the 60,000-pound elephant in the room.” He acknowledged the prohibition on a new ergonomics standard, but said, when it comes to ergonomics, “we can fix this.”

Benefits of Good Ergonomics Increased productivity Decreased injury risk Decreased mistakes/rework Decreased lost work days Increased efficiency Decreased turnover Improved morale

WMSD Risk Factors In the 90s NIOSH undertook significant research to identify the key workplace risk factors leading to musculoskeletal disorders. This is a chart from one of their publications – NIOSH 97-141 – that details the evidence. Identifying the risk factors for ergonomic injuries in your workplace is the first step to improvement.

Common WMSD Risk Factors Force Vibration Posture Environment Frequency Personal Factors Duration

Risk Factors for Injuries Forceful Exertions Weight of load Location Frequency Stability Coupling Awkward Postures Bending Twisting Reaching

Risk Factors for Injuries Repetitive Motion Frequent reaching Assembly tasks Keying Packaging Vibration Tools Mechanized Equipment

Awkward Postures - Low work Bending Kneeling Squatting If the location of your work is too low, you’re going to have to get into an awkward posture to get to it. Typically that means bending your back, kneeling or squatting. It can also mean bending your head and neck forward. If ergonomics is about adapting the work to fit you, instead of asking you to adapt to the work, what do you think some ergonomic solutions might be? These postures are hard on the back and the knees

Implementing Ergonomic Controls Elimination Substitution Engineering Control Policies PPE 8 Deadly Wastes Tools, Equipment, Processes Effectiveness Workstation Design, Mech. Assist After we identify risk factors, what do we do about them… Assess the risks – use checklists, analysis tools, etc. to determine where the risk is significant Develop solutions – hierarchy of controls Often we go right to PPE or work practices…but, often these can be highly ineffective for ergonomic interventions. Elimination – is this activity value added Substitution – can we do the task another way, or use different tools, equipment, etc to accomplish the task. Engineering controls – redesigning the workstation, adjustability Policies – work practices, techniques, rest breaks, job rotation PPE – none!!

Reducing low work Raise and/or tilt the work for better access Use a stool for ground level work Use tools with longer handles Alternate between bending, kneeling, sitting, and squatting If the work is too low, one solution to consider is finding a way to raise the work. If that’s not possible, can you use a low stool to provide support so that you can sit lower near the level of the work? Long-handled tools can be used in some cases so that you can stand upright and work. If none of the above will work, it at least helps some to alternate between different postures, so that you don’t spend too much time in any one position.

Ergonomics at Work Reducing low work Raise and tilt the work This is one example of a simple way to raise and tilt lightweight boxes for easy loading and unloading. It’s a box stand made out of PVC pipe. For $20 worth of pipe and glue, and a little time measuring and cutting with a hacksaw, some workers were able to make their jobs a little easier.

Ergonomics at Work Reducing low work Raise the work This is another example, where some workers decided it would be easier to stack lengths of pipe at the end of the process if they raised the stack a little. Placing the stack on a homemade wheeled cart makes it easier to move to the next step.

Meter reader – golf club handle extension Ergonomics at Work Reducing low work Meter reader – golf club handle extension This person fitted the tool (a long screwdriver) he uses for opening water meter covers, with a golf club handle. This allows him to open and close the meter box without bending, kneeling or squatting.

Awkward Postures High work If your work is too high, it will result in reaching with your hands overhead or your elbows above your shoulders. It can also result in having to tilt your head back to look up. This posture is hard on the shoulders, neck and back

Reducing high work Use an elevated work platform or rolling stairs Use tools with longer handles Limit overhead storage to infrequently used items Bring the work down and tilt for easier access Here are some simple ways to reduce working up high: Use an elevated work platform or rolling stairs (“safety ladder”) Use tools with longer handles Limit overhead storage to infrequently used items Bring the work down and tilt it for easier access

Use a tool with longer handles Ergonomics at Work Reducing high work Use a tool with longer handles Our groundskeeper has gone from using a standard hedge trimmer to one with an extension handle. The trimmer at the top has an adjustable angle. Long-handled tools need to be kept as light as possible, to avoid straining the hands and wrists. Look for lightweight materials such as aluminum.

What are some of the symptoms of WMSDs? Discomfort Burning Pain Swelling Numbness Change in color Tingling Tightness, loss of flexibility Report symptoms if: Pain is persistent, severe or worsening Pain radiates Symptoms include numbness or tingling Symptoms keep you from sleeping at night WMSDs have many different symptoms, many of which you may have experienced at one time or another. These include discomfort, pain, numbness, tingling or burning sensations, swelling and inflammation, changes in skin color, and tight muscles or loss of flexibility in a joint. Having one or more of these symptoms doesn’t necessarily mean you have an injury, though. Everyone has had muscle aches or stiffness after working or exercising hard, especially when you’re not used to it. Usually these symptoms go away as you rest or as you get used to the work. That’s different from symptoms of injury, which last longer or include things like numbness and tingling that mean something more serious might be going on. Sometimes these symptoms might make it difficult to do your job or things around the house, or they might wake you up at night and keep you from getting a good night’s sleep. The important thing is not to ignore what your body is trying to tell you. Often simple changes to the way you work are all that are necessary to prevent these symptoms from becoming a WMSD.

Why is it important to encourage reporting of symptoms? Minor injuries can easily become chronic injuries Injured workers, absenteeism, turnover, insurance costs Can lead to surgery and disability Early treatment is more successful Some WMSDs can be very serious, resulting in lost work days, permanent disability, or even surgery. However, the good news is that early treatment is often very simple and successful. Therefore, it’s important for your own health to report symptoms as early as you can.
