6 Ways To Prevent Repetitive Strain Injury In The Lab

What is RSI?

RSI is an acronym for repetitive strain injury which occurs when the same physical movements are repeated over an extended period of time. A repetitive strain injury is an injury to a part of the body that is caused by overusing or straining that body part. “Strain occurs when the body part is called on to work harder, stretch farther, impact more directly or otherwise function at a greater level than prepared for¹.”

RSIs can do damage to tendons, nerves, muscles, and other soft body tissues. Repetitive strain injury generally results from using the body for a task that it is either not designed to perform or capable of comfortably working. Although (RSI) is frequently associated with computer users, it can also affect those who work in the laboratory.

Have you ever experienced aches and pains after a long session of pipetting? Have  you ever experienced numbness, tingling, or a burning sensation in your arms and forearms? If you answered yes, to either or both of those questions, you may be experiencing symptoms of repetitive strain injury. Worn pipettes and poor pipetting techniques are two primary factors that contribute to laboratory RSI.

Repetitive Strain Injury In The Laboratory

Did you know that pipetting in the laboratory is one of the most repetitive tasks in the lab? 

Pipetting is commonplace in the laboratory, so, it is not too hard to believe that hand pain due to pipetting is also a common problem in the lab. Although RSI is frequently associated with computer operators, laboratory technicians have reported hand and shoulder ailments while using modern plunger-operated pipettes.

Hand And Shoulder Ailments Among Laboratory Technicians Using Modern Plunger-Operated Pipettes.

In a 1994 study conducted in Sweden, 128 female laboratory technicians employed by university research laboratories working with plunger-operated pipettes were compared to 25,378 female Swedish state employees in general. “The prevalence of hand ailments among the laboratory assistants was found to be twice that among female state employees in general.” The study also found that pipetting for more than 300 hours per year contributed to an increased risk of hand and shoulder ailments.

A questionnaire survey of the ergonomic problems associated with pipettes and their usage with specific reference to work-related upper limb disorders.

A study conducted in 1997 in the United Kingdom, which comprised of 80 pipette users and 85 non-pipette users (control population) determined that the reported occurrence of elbow and hand complaints were significantly higher for the pipette users. “There is an increase in the percentage of those reporting hand complaints as the duration of the working period involving continuous use of pipettes increases.” An astounding 90% of pipette users who exceeded 60 minutes of continuous operation reported hand complaints.

Symptoms Of RSI

Although they may vary, symptoms generally include pain, fatigue, tingling, clumsiness, coldness, and numbness in the arms, legs, neck, upper and lower back. For example, computer users may experience pain in their arms after extended periods of typing. Some computer users who switch from doing a majority of typing on their desktop to a laptop may experience pain shortly after the switch. Symptoms will develop gradually and will continue to worsen over time if left untreated. For lab technicians using pipettes, symptoms mainly occur in the shoulders, arms, and hands.

Look for these warning signs:

  • Muscle discomfort
  • Aches and pains
  • Coldness
  • Muscle tension
  • Tingling and numbness

Causes Of RSI

Although there a number of factors that can cause RSI, performing repetitive tasks such as pipetting, where the hand and arm muscles are held tight and tense for extended periods of time, can lead to the development of RSI. As muscles and tendons become overused they may be strained beyond their capacity.

Listed below are factors that can lead to RSIs:

  • Repetitive movement (e.g. pipette plunger)
  • Awkward postures
  • Prolonged muscle tension (e.g. holding pipette)
  • Forceful holding or movement (e.g. liquid transfer from one receptacle to another)
  • Poor ergonomics
  • Poor work practices (e.g. improper pipetting technique)
  • Stress (e.g. cluttered lab)

Identifying the root cause is essential to properly treating RSI. Left untreated symptoms will gradually worsen and could ultimately impact your bench science career.
6 Tips To Prevent RSI In The Lab While Pipetting

Although these tips are geared mainly towards pipetting, they can easily be applied to other repetitive tasks that you perform throughout the course of a normal day in your lab.

1) Relax

Stay relaxed physically and mentally while pipetting. As discussed earlier, stress, prolonged muscle tension, and poor ergonomics are all contributing factors to developing repetitive strain injury. Avoid awkward positions while pipetting and make sure to follow proper pipetting techniques.

2) Maintain Good Posture

Regardless of the activity, typing a report on your computer or pipetting, you want to ensure that you are sitting properly and maintain good posture (your back will thank you). Your spine is strong and stable when you practice healthy posture. Slouching makes it difficult for your muscles and ligaments to keep you balanced and can lead to back pain, headaches, and other problems. Avoid dangling your feet, hunching your shoulders, or contort your neck when pipetting liquids.

3) Ergonomics

Ensure that your chair or stool is appropriate for the task. Most chairs offer multiple adjustment options to elevate or lower you to the specific height required for the task. Remember that poor ergonomics and poor posture can lead you to developing RSI.

4) Use A Timer

The longer the repetitive activity, the greater the chance of developing an injury. Incorporating a lab timer into your work process will ensure that you provide yourself with the necessary breaks to prevent strain from pipetting, as well as a mental break that will allow you to refocus on the task at hand.

5) Just Say No To Clutter

An organized lab is a happy lab. By organizing your workstation you will reduce clutter, increase lab safety, and improve overall ergonomics. If you organize your workstation properly, you can determine which supplies (pipette tips, buffers, samples) you need on a regular basis and place them accordingly while minimizing awkward postions. I encourage you to check out our post on The 5S Approach To A Lean Lab for more information regarding this topic.

6) Find The Right Pipette

Not all pipettes are created equal. There are many different pipette manufacturers and models available. One major factor to consider when either using your current pipette or selecting a new one is the operational pressure required to operate the pipette. If you have already begun to experience pain while pipetting, you may want to consider a pipette model that requires reduced operating forces. Additionally, you will want to review the weight of the pipette and the ergonomics (finger hook, plunger configuration, tip ejector).Another alternative for those who are already experiencing symptoms of RSI would be to consider an electronic pipette, they may be heavier but require little operating force to aspirate and dispense. After you have selected your pipette or reviewed your existing pipette, make sure that you are using a compatible pipette tip.

Now that we have covered what repetitive strain injury is, the symptoms, how it is caused, and six tips to help you avoid developing repetitive strain injuries while working in your laboratory, you can now be able to get back to pipetting safely.

What To Do If You Think You Have RSI

If you have experienced or develop these symptoms it is recommended that you speak with an occupational health professional at your facility or your physician.

The 5S Approach To A Lean Lab

What is Lean?

Lean production (lean) is a popular quality improvement methodology that can be traced back to manufacturing and technology. Lean manufacturing principles can be used to improve efficiency in the laboratory environment. Lean has been adopted by many health care organizations and laboratories to help eliminate waste, organize the workplace, streamline procedures and establish clear, visual standards.

According to a 2007 white paper written by the Mayo Clinic Mayo Medical Laboratories “Innovations in the Clinical Laboratory – An Overview of Lean Principles in the Laboratory,” Lean is a based on eliminating waste and continuous improvement: “This is done while intently concentrating on eliminating redundant motion, recognizing waste, and identifying what creates value from the client’s perspective. Lean is a continuous process improvement initiative and not an end destination.”

What is 5S Lean?

The disciplined approach of the lean methodology provides many benefits:

  • Reduces waste/clutter
  • Creates a culture of responsibility
  • Increased lab safety
  • Enhance employee morale and involvement
  • Organization
  • Cleanliness
  • Space savings
  • Increases inventory control
  • More consistent experiments
  • Increases productivity
  • Faster onboarding of new employees
  • Timely delivery of supplies

Simply put, 5S Lean is an enabler of waste-free production that supports an operating philosophy that emphasizes discipline, efficiency, and attention to detail. In the modern lab, where many labs have faced reduced budgets and fewer staff members, adopting the lean methodology can result in a more cost-effective and safer way to manage processes. Applying the 5S lean methodology in the laboratory environment will improve efficiencies and lab safety for current and future employees.

What are the 5 S’s?

There are five phases of the 5S Lean methodology, you may be familiar with the Japanese names, here are the five phases translated into English. It is important to note that you will want to establish a baseline for the target work areas before you begin the implementation process. This way you are able to document your baseline “before” condition with pictures and a description of the original work area configuration to use as a comparison during future audits.

  • Sort
  • Set in Order
  • Shine
  • Standardize
  • Sustain

Sort (Seri) is based on removing unnecessary items and disposing of them properly. Work is made easier by eliminating obstacles and you will reduce the chance of being disturbed by unnecessary items in the lab. This phase will also help prevent the accumulation of unnecessary items and it will also assist in the evaluation of necessary items with regard to debt, cost, and other important factors.

Key steps

  • Establish a holding area for items (e.g. red tag area)
  • Identify items not required at the current location
  • Organize team members to evaluate items in the holding area
  • Dispose of items with team approval

Set in Order (Seiton) is where you arrange all necessary items in order so they can be easily picked up for use. This phase focuses on preventing loss and wasting time, making it easy to find and identify the necessary tools, equipment, and supplies. You will want to identify sources of waste and rearrange items.

Key Steps

  • Identify necessary tools, equipment, and supplies
  • Determine location for necessary items
    • Item location considerations (pipettes will be used daily)
      • Daily use (lab bench) e.g. Pipettes
      • Weekly use (common storage area) e.g. buffer solutions
      • Monthly use (remote storage area) e.g. highly specialized lab items
  • Designate and outline permanent locations for items
    • How to set in order
      • Define the major processes performed
      • For each process, draw a map of the locations of each activity
      • Identify sources of waste and develop corrective measures
      • Position items where they are needed based on frequency
  • Organization of supplies
    • Determine address system with part number and address
    • Label container with part number
    • Note minimum and maximum quantity if appropriate
      • Inventory bins and shelves (holding product)
        • 2 bin system (2 bins for each product and once 1 bin is empty you will want to refill the bin)
        • Min/Max (max red line and minimum green line)
      • Relocating laboratory equipment such as digital dry baths, mini water baths, microscopes that are located throughout the laboratory into a more convenient location that is within reach and an open workspace.

Shine (Seiso) or clean is an important phase, especially while working in the laboratory environment. By thoroughly cleaning your work areas in the laboratory, you use cleaning as a means of inspection, you can keep your lab area safe from hazards and clutter which can result in inefficiencies. Getting in the habit of cleaning and inspecting your laboratory work space you will be able to identify leaks, spills, potential contamination, or any other minor problems that could turn into larger problems down the road.

Key Steps

  • Clean thoroughly – really make it shine!
  • Clean and inspect lab work areas daily to identify any potential issues or problems

Standardize (Seiketsu) phase is focused on maintaining order and adhering to a set standard. This is where you or your team will develop standard operating procedures (SOPs) which help in the in the on-boarding of new employees, saves time for routine tasks and improves overall efficiency. You will also want to document equipment and processes while developing an audit schedule and assigning specific tasks to individuals. Establishing a methodology to ensure a consistent strategy for successful 5S implementation is an important consideration and will impact the overall effectiveness of the initiative.

Key Steps

  • Develop SOPs (standard operating procedures) Helpful for new employees, saves time and improves efficiency
  • Document equipment and processes
  • Develop and audit schedule and assign tasks to individuals
  • Establish a methodology to ensure consistent strategy for 5S implementation
    • 5S taping standard
      • MIcroscope room (blue and yellow tape)
      • Standardize a bench (each bench has a standard layout)
        • Storage area for chemicals and solutions
          • Pipettes, sharps containers and tips
          • Biological cabinet (no tape) post a picture instead

Sustain (Shitsuke) is the most challenging and difficult stage for most organizations. Although this may be the most trying of phases, it is also the one with the largest payoff. You will want to regularly communicate and train employees to adopt the 5S methodology and adhere to the 5 phases to keep your lab running smoothly and efficiently. This portion of the 5S will have the highest level of variability since every lab and organization is different. It is important to define your measures of performance (MOPs) early, doing so will allow you to begin tracking your results immediately.

Key Takeaways

  1. Sort, separate what is unnecessary
  2. Set in Order, organize
  3. Shine, clean up
  4. Standardize, establish standard operating procedures
  5. Sustain, develop long-lasting habits

“The main objective of Lean, when applied in the laboratory, is to deliver quality patient laboratory results, at the lowest cost, within the shortest time frame while maintaining client satisfaction.” -Mayo Clinic Mayo Medical Laboratories

The Lean methodology is an extremely powerful tool when used properly. Every organization is different and this methodology will have to be adapted to your organizations unique needs and requirements. Remember, driving lean improvements can seem challenging at times, but when you utilize the proper tools, approach, and support, you can make a difference in your organization.

4 Unique Ways To Safely Store Your Pipettes

Pipettes are designed to efficiently deliver a small measured fixed volume of liquid into a receptacle. Proper handling and storage techniques are important to maintain accurate readings and maximize their longevity. Liquid handling equipment must be stored correctly to prevent inaccuracies and produce accurate outcomes.

Pipettes are precise laboratory instruments and need to be properly cared during and after each use. It is recommended that you visually inspect your pipette for damage on a daily basis to avoid undesirable outcomes. For example, damage to the nose cone (where the tip is fitted) could result in a poor seal to the pipette tip, which will reduce accuracy and it is unlikely to be fit for the job you need it for.

Pipette Storage Tips

Once you have finished pipetting you will want to ensure that you store your pipette vertically using a pipette holder, stand or workstation. Following these simple steps will prevent any liquids from seeping into the barrel of the pipette and causing damage by corroding the barrel or shaft. Never put your pipette on it’s side with liquid in the tip, this can cause the same issue with corrosion and can be avoided by properly storing your pipette.

Although it is recommended that pipettes are serviced and calibrated at least once a year, taking a few minutes each day to make sure the pipettor is stored properly will save you the time and expense of having to send the pipettor off for maintenance more frequently. Remember that good routine maintenance and care helps prevent costly repairs.

Pipette Storage Options

There are a number of storage options for your pipettes depending on your laboratory and workstation configuration. Safely storing your pipettes when not in use is important, but you also want to make sure that you can access them quickly and easily as well. Listed below are four different style pipette storage options that can enhance your labs changing needs.

  1. The Flip & Grip Pipette Holder is a unique pipette holder that gives you the option of using it on your bench top, or as a hanging under shelf holder to help maximize your working space available. This pipette holder can hold up to 12 single channel pipettes, or a combination of 3 single channel and 3 multichannel pipettes. The unique rubber grips prevent scratching and is compatible with most common pipette brands. The holder rotates for quick and easy pipette selection and storage.
  2. The Clamp-Ette Pipette Holders makes pipette storage quick and easy. These pipette holders are available in single and triple formats and are compatible with most major pipette brands. The Clamp-Ette secures to tabletops, benches, and shelves with a simple twist of the fingertips, creating an instant pipette holding point within your laboratory. This unique autoclavable pipette holder is available in blue, red, and purple to match your lab and personality.
  3. The Pipette Workstation is the perfect solution for organizing your pipettes and pipette tips in one convenient location. The acrylic rack is opaque on the sides but has clear front and bin lids for easy pipette tip identification. This workstation will hold up to four pipettes and included two dust-free storage bins for different sized tips. The oversized lip on the lid provides easy access even wearing gloves. Organize your pipette and tips in one convenient location in your workstation.
  4. The pipette stands are available in several sizes, materials, and color options. These classic 3, 4, and 6-place pipette stands are designed to hold most major pipette brands. The 6-place pipette stand is available in clear acrylic, blue fluorescent acrylic, and dark blue ABS plastic for increased durability. The 3 and 4-place pipette stands come in clear acrylic for enhanced visibility and easy identification.

Protect Your Investment

There are a variety of pipette storage options available that can adapt to your labs changing needs. Your pipettes are precise liquid handling instruments and should be treated and stored with care to protect your investment and continue producing accurate results. Selecting the proper storage rack or stand will ensure that your pipettes are safe and organized, reducing clutter in your laboratory and improving your efficiency.
