20+ points for best answer! 1. why is it important that employees know the difference between a safe and an unsafe workplace? 2. what is the difference between body mechanics and ergonomics? 3. why do employees need to be informed of areas where potentially hazardous chemicals and radiation are used? 4. why do those with professional licenses or certifications still need training throughout their careers? 5. list three things that patients can do to reduce chances of medical errors.

1. It is important for employees to know what qualifies for a safe workplace so that they will be inclined to follow safety principles to prevent any accidents happening in the workplace. Knowing the difference between safe and unsafe working environments is important to enlist their cooperation in maintaining a safe work environment.

2. Body Ergonomics gives the safest and stress-free ways in which work can be done in accordance with the body's natural movement. It also allows for good body mechanics to occur.
 Body mechanics, on the other hand, studies the ways in which a body makes a movement maintaining proper muscular and skeletal positions during movement.
3. Employees need to be informed of areas with hazardous chemicals and radiation so that they can avoid unnecessary exposure by going to these places. Employees need to know that these are restricted areas that need proper PPE (personal protective equipment) so as to avoid unnecessary accidents. 
4. People with professional licenses and certificates need to continue upgrading their skills and techniques by training because revisions are made all the time. New discoveries and studies change old practices. Modern equipment keeps on evolving and so should the professionals that use them. Constantly evolving with the world will make a professional more desirable in his chosen field. 
5. Patients can do the following to reduce medical errors:
- Being truthful and open to all facts during history taking: Patients should learn to trust their health care providers by giving them the exact, complete information asked of them during history taking. Keeping or withholding information from a practitioner can lead to serious medical errors.
- Failure to follow medical instructions: For example, an outpatient was given medical instructions to follow upon discharge. However, the patient failed to follow the instructions and made himself sick again leading to a failure of medical treatment. 
- Self-medicating: Patients often do this to lessen medical costs. However, misinformed judgments can cause the actual and proper medical treatments to be ineffective.
