What is the universally accepted standard of flexibility that you should compare yourself against?

There is not such thing as a universally accepted standard of flexibility because there's no material that is taken as a reference point. You can't say it's twice the flexibilty of rubber or twice the flexibilty of bamboo or anything similar because no official reference points have been established in the SI system.

It starts with commitment. the health and safety policy is the commitment by the employer to provide and maintain a safe workplace. the commitment of the workforce is also a necessary component.when the workplace parties sit down to develop an ergonomic approach to patient handling, they will develop terms of reference that set forth how the health and safety committee will function in approaching this problem and reach its goal of reduced injuries.in general, a safe patient handling program will involve the following steps: management approval and commitment to develop and implement a patient handling program.perform a needs analysis.create and standardize patient assessment criteria.develop decision trees to standardize actions.determine which controls are needed to implement specific tasks or patient needs.institute a "no-lift" policy, where possible.
