What is Ergonomics?

Ergonomics is a multidisciplinary field drawing primarily from the fields of engineering, physical sciences, biological sciences, and social and behavioral sciences. The primary goal of ergonomists is to develop systems and products which increase productivity, function intuitively, and minimize the risk of injury and illness to the people that use them. Ergonomic principles have been applied in a wide variety of industries and depending on the commitment of the organization, results can be extremely positive. The basic principle of ergonomics is “fit the task to the worker”. Therefore, it is very important to be aware of the tasks to be performed by the workforce and the capabilities of the workforce already employed or soon to be employed.

“Fit the Task to the Worker”

Why is Ergonomics Important?

Ergonomics can be used by itself or in conjunction with other efficiency techniques to:

  • Increase Productivity
  • Improve Work Quality
  • Improve Health and Safety
  • Improve Worker Quality of Life
  • Decrease Workers Compensation Costs
  • Decrease Rework and Scrap Related Costs
  • Reduce the likelihood of OSHA fines

Where can Ergonomics be applied?

Ergonomics can be applied in almost any situation. Our ergonomists have experience in a number of fields including aerospace and automotive manufacturing, warehouses, office environments, semiconductor manufacturing and assembly, and retail.

What should I consider when it comes to Ergonomics?

To gain the greatest advantage, Ergonomics should be implemented as a comprehensive program. However, sometimes organizations need assistance with just one aspect of the program. Some program elements include:

  • Developing a Written Ergonomics Program
  • Conducting Training (for Managers, Employee, or other Personnel)
  • Hazard Identification (e.g. Evaluation of tasks, work areas, or jobs)
  • Hazard Control Methodologies (e.g. Recommendations to reduce risk)
  • Medical Management (e.g. injury tracking, trending, and analysis)
  • Program Gap Analysis or Benchmarking
  • Program level corrective action
  • Plan Development

Ergonomic Program Development and Implementation

What are the Advantages of an Ergonomics Program?

An effective ergonomics program benefits both employers and employees through improved health and safety, productivity, and lowered costs. Specifically, ergonomics can be used by itself or in conjunction with other efficiency techniques to:

  • Increase Productivity
  • Improve Work Quality
  • Improve Health and Safety
  • Improve Worker Quality of Life
  • Decrease Workers Compensation Costs
  • Decrease Rework and Scrap Related Costs
  • Reduce the likelihood of OSHA fines

What is an Ergonomics Program?

An ergonomics program is a comprehensive approach to ergonomics within an organization. Ergonomics programs can be implemented in manufacturing, service, government, and non-profit organizations. The elements of an ergonomics program are the same, although the way these elements are executed within an organization may differ depending on needs, industry, and organization size. The elements of an ergonomics program include:

  • Management commitment
  • A Written Program
  • Employee Involvement
  • Training and Education
  • Worksite Analysis
  • Hazard Prevention and Control
  • Medical Management
  • Program Review and Evaluation

What are the steps in developing an Ergonomics Program?

As with the development of any comprehensive program, there are a number of steps that should be followed when developing an ergonomics program. These steps are often organization specific, but generally include the following:

  • Establish management commitment
  • Identify organizational needs
  • Determine ergonomics program goals and indicators
  • Determine the level of staffing needed for a successful program. This could include staffing of committees and consultants as well as existing resources.
  • Develop a written program
  • Identify the best method for worksite analysis (consultant, in-house expert, etc.)
  • Develop a mechanism to identify hazards
  • Determine an evaluation scheme for assessing recommendations to reduce ergonomic risk
  • Establish a medical management program for injuries
  • Develop a communication plan for managers, employees, and other individuals
  • Identify training needs and opportunities

What are the steps in implementing an ergonomics program?

The steps to implementing an ergonomics program are organization dependent but always have the same first step and the same last step. The first step is always establishing management commitment. The last step is always evaluating and improving the ergonomics program. The sequence and specific steps in between are customized to the needs of each organization and generally follow the elements of a successful ergonomics program.

Ergonomics Training

What is Ergonomics Training?

Ergonomics training is a specific type of training that aims to teach individuals specific information related to ergonomics in their work environment. Training should incorporate a number of methods (visual, logical, verbal, physical and aural aspects) in order to ensure that people with different learning styles have an opportunity to acquire the information. As with any training effort, ergonomics training establishes a baseline knowledge and vocabulary related to ergonomics. This common vocabulary is effective in establishing dialog related to risk factors and opportunities for improvement.

Why is it important to Train Managers on Ergonomics?

Training of managers and supervisors should not be overlooked in any training program. Managers and supervisors should receive ergonomics training so that they are aware of the information that is being communicated to all employees. Additionally, management and supervisor training should include aspects related to investment, ways of showing management support, impact on productivity and efficiency, as well as possible reductions to bottom line costs within the organization.

What should be Included in the Management Ergonomics Training?

Management ergonomics training should include the following topics:

  • Definition of ergonomics
  • Aims of an effective ergonomics program
  • Aspects of an effective ergonomics program
  • Basic principles of ergonomics
  • Overview of proper equipment and hand tool use
  • Overview of proper lifting
  • Symptoms of musculoskeletal disorders
  • Importance of early reporting
  • Overview of reporting and medical management process
  • Role of managers in the injury investigation process

Why is it important to Train Employees on Ergonomics?

Training employees is an important part of any successful ergonomics program. Increasing the level of knowledge of the employees serves a number of purposes. It establishes a common vocabulary among employees so that they can discuss concerns in a meaningful way. Training also provides information to employees so that they can be empowered to make better decisions regarding how they work and the postures (or hand tools) they use to complete their work tasks safely.

What should be included in the Employee Ergonomics Training?

Employee ergonomics training should include the following topics:

  • Definition of ergonomics
  • Basic principles of ergonomics
  • Proper equipment, machine, and hand tool use
  • Proper lifting techniques
  • Symptoms of musculoskeletal disorders
  • Aspects in the work environment that may relate to increased risk of injury
  • Importance of early reporting
  • How to report an injury

Is it necessary to conduct re-training?

It is necessary to continually remind employees of the basic principles of ergonomics. Thus, retraining at a regular frequency is strongly recommended. It may not be necessary for individuals to sit through the same, initial training annually. However, it is necessary to remind employees and managers of the important aspects of ergonomics (definition, principles, risk factors they are faced with, how an individual can reduce their risk, and the importance or early injury reporting) at least once a year. Additionally, regular re-training provides an opportunity to emphasize current issues or trends related to ergonomics and injuries as they arise.

Ergonomic Workplace Evaluation

What is an Ergonomic Workplace Evaluation?

An ergonomic workplace evaluation is an assessment in an office, laboratory, or other work environment that is conducted with the aim to identify ergonomic risk factors and recommend ways that these risk factors can be reduced in order to reduce the risk of work related musculoskeletal disorders.

Why are Ergonomic Evaluations Important?

Ergonomic evaluations that are performed by an experienced ergonomist can accurately identify the level of risk present in a job or task. Understanding the nature of the risk and the relative severity of that risk is important so that changes can be made to reduce specific risk factors. Reducing injury related risk factors is an important step in reducing the number and severity of injuries as well as improving the overall work environment, productivity, process flow, efficiency, and associated costs.

Is Special Training Required to Perform an Ergonomic Evaluation?

Ergonomic evaluations of complex environments (such as laboratories, manufacturing, services, or jobs that have already caused injury) should be performed by an experienced, certified ergonomist. The certifying body for ergonomists within the United States is the Board of Certification in Professional Ergonomics (BCPE). Certified ergonomists are uniquely trained to take a systems approach to the evaluation of many work, product, or service environments from the perspective of an individual’s cognitive and physical capabilities.

How are Evaluations Prioritized?

Any effort to evaluate a number of workstations requires that the order of evaluation be prioritized. The order of evaluations can be determined based on a variety of criteria. These criteria may include frequency and severity of previous injuries, perception of risk, business priority, number of employees affected, and other factors as determined by safety or ergonomic criteria or business need.

What should be included in Ergonomic Workplace Evaluations?

OSHA suggests that workplace ergonomic evaluations should use a systematic approach to the identification and quantification of risk factors that may be present in a job or task. Evaluations should also:

  • Pay particular attention to postures, forces, frequencies, vibration, and weight handled
  • Identify tasks that may have fewer risk factors as possible tasks for restricted duty
  • Evaluate the changes made to jobs or tasks to determine if risk has been reduced, eliminated or inadvertently introduced.

What is the outcome of an Ergonomic Workplace Evaluation?

Once the risk factors are identified and quantified, a typical evaluation provides suggested methods that are aimed to reduce the identified hazards without introducing additional risk factors. When considering alternatives to reduce injury risk factors four primary controls are often utilized.

  • Engineering controls: Engineering controls include workstation design/redesign, work method design, or tool design.
  • Work practice controls: Training and assessment, proper work techniques (e.g. lifting techniques).
  • Personal protective equipment: Safety glasses, hard hats. Back belts and wrist splints are not recognized as personal protective equipment.
  • Administrative controls: Preventive maintenance, worker selection, work pace/frequency, work/rest periods.
