What are Snook Tables?

‍

Snook tables are ergonomic tables that help determine the recommended heights of worksurfaces, seating, and other components of a work system based on the anthropometric measurements of the intended users. 

Snook tables are utilized to determine the best working levels for different tasks and to ensure that a work system is designed to fit workers as opposed to having workers adapt to the work system. 

This involves providing them with all the necessary safety equipment and training. However, workplace safety is not limited to the right equipment and training but also includes paying attention to ergonomics. Snook tables can be used to enable workplace safety.

The Importance of Using Snook Tables in the Workplace

‍

The primary importance of snook tables in the workplace lies in their ability to mitigate the risk of musculoskeletal injuries. 

These injuries are not only detrimental to employee health and well-being, but they also lead to reduced productivity and increased absenteeism. 

By referring to snook tables, organizations can design and implement effective ergonomic solutions that minimize the physical stress on employees, thereby reducing the likelihood of injuries caused by repetitive lifting, bending, or twisting motions. 

Furthermore, snook tables provide guidelines that promote equitable workload distribution, fostering a sense of fairness among employees. By using these tables, managers can allocate tasks according to individual capacity, which can lead to greater job satisfaction and higher employee morale. 

This, in turn, can have positive effects on employee retention, as well as a company's overall reputation. Another significant benefit of utilizing snook tables in the workplace is the potential for cost savings. 

Work-related musculoskeletal injuries often result in significant medical expenses and workers' compensation claims. By implementing ergonomic solutions informed by snook tables, organizations can potentially lower these costs, leading to improved financial performance. 

This proactive approach to workplace safety also demonstrates a company's commitment to employee welfare, which can enhance its brand image and attractiveness to prospective employees.

How Snook Tables Work

‍

These tables are based on extensive research conducted by Dr. Stover H. Snook and Dr. Vincent M. Ciriello at the Liberty Mutual Research Institute for Safety. 

The tables provide a systematic approach to evaluate the physical demands of manual material handling tasks, taking into account various factors that influence the risk of musculoskeletal injuries. 

The snook tables work by considering several critical variables that contribute to the strain on the human body during manual handling tasks. These variables include the weight of the object being handled, the height at which the object is lifted or lowered, the distance it is carried, the frequency of the task, the duration of the activity, and the angle of the body while performing the task. 

The tables also account for individual differences, such as the worker's gender, age, and physical fitness level. To use snook tables effectively, the evaluator first gathers data on the task to be assessed, such as the weight of the object, the height from which it is lifted, and the distance it is carried. 

Then, the evaluator consults the appropriate snook table, which provides percentage values representing the population capable of performing the task safely under the given conditions. For example, a value of 75% indicates that 75% of the working population can safely perform the task without a significant risk of injury. 

The snook tables help organizations establish safe limits for lifting, lowering, pushing, pulling, and carrying tasks by determining the maximum acceptable weight or force for a given set of task conditions. 

When the identified limits are exceeded, the risk of musculoskeletal injuries increases, and organizations are encouraged to implement ergonomic interventions or alternative methods of material handling. 

These interventions may include using mechanical aids, redesigning the workstation, or adjusting the work process.
