Acute:◦ Result from a one time event
Cumulative:◦ Result from repeated wear and tear;
however, a specific event may have been “the last straw” upon a previously weakened system and thus give the appearance that the problem is acute rather than chronic. {Stephen Konz. “Work Design; Industrial Ergonomics”, Third edition. 1990}

Safe Lifting Techniques
There are several basic rules of lifting and moving that can help prevent back injuries:
• Lift with your legs, not your back; this is because your legs muscles are larger and better positioned over the hips and knees to provide this activity.
• Do not twist; instead, always position your hips and feet toward the object you are lifting or moving.
• Maintain the natural curves of the neck, upper back and lower back while lifting, moving, and even sitting.
• Keep objects close to your body; this reduces the leverage on your spine.
• Push, rather than pull when possible. Pushing naturally places your legs in a position to do the work whereas pulling naturally places your back in a forward bent position.

• Minimize pushing/pulling• Minimize load weights• Slide objects• Lower loads rather than lift• Use gravity• Avoid double handling• Use suitable containers• Provide comfortable hand holds• Remove constraints/obstacles• Avoid placing loads on the floor
