TOOLS FOR ANALYSING THE RISK FACTORS OF MSDS

This ergonomic analysis tools provides you with all the tools for a complete analysis of biomechanical risk factors leading to MSDs.

RULA method PDF

The RULA quotation grid

The RULA grid is a method used to evaluate upper limb postures and highlight the risks associated with observed work cycles. The final RULA score ranges from 1 to 7.

The REBA quotation grid

The REBA grid is a whole-body postural risk assessment method based on the same scoring principle as RULA. The final REBA score varies from 1 to 15.

Illustration equation de NIOSH

NIOSH equation

The NIOSH equation is an evaluation method for manual material handling tasks. The recomanded weight limit can be calculated from the workstation parameters, with the lifting index indicating the level of risk. 

BORG effort perception scale

The Borg scale is a quantitative tool that subjectively assesses the level of effort during physical work. It is used to quantify the intensity of effort and occupational health monitoring of lumbar risk for workers exposed to manual handling activities. The Borg scale CR10 is used to assess the perception of intensity of the effort.

OCRA method

The OCRA Method in ergonomics assesses and minimizes risks associated with repetitive tasks by analyzing factors like posture, force, and task duration, aiming to prevent musculoskeletal disorders.

IMG titre EAWS

EAWS method

The EAWS method is an evaluation method that combines aspects of posture, load handling and repetition. This method is used for proper organization and work planning.

RULA method PDF

The RULA quotation grid

The RULA grid is a method for evaluating upper limb postures. It highlights the risk of postures related to the observed work cycle. The final RULA score varies from 1 to 7.

The REBA quotation grid

The REBA grid is a whole body postural risk assessment method. It is based on the same scoring principle as RULA. The final REBA score varies from 1 to 15.

Illustration equation de NIOSH

NIOSH equation

The NIOSH equation is an evaluation method for manual material handling tasks. The maximum permissible load can be calculated from the workstation parameters, with the lifting index indicating the level of risk. 

BORG effort perception scale

The Borg scale is a quantitative tool that subjectively assesses the level of effort during physical work. She is used to quantify the intensity of effort and occupational health monitoring of lumbar risk for workers exposed to manual handling activities.

OCRA method

OCRA is a repetition/stress evaluation method for the upper limbs. It allows the analysis of tasks that involve repetitive movements and/or stresses of the upper limbs.

EAWS method

The EAWS method is an evaluation method that combines aspects of posture, load handling and repetition. This method is used for proper organisation/work planning.
