Hey there!
Here is your answer:
<u><em>The proper answer to this question is "OSHA is </em></u><span><u><em>"assure safe and healthy working conditions for people by enforcing standards and by providing training".</em></u>
Reason:
</span><span><u><em>OSHA ( Occupational Safety Health Administration) is used in order to help train workers to use equipment, manage files, etc... (anything to do with there work) This was established by president Nixon in order to protect men, and women in there work place.</em></u>
<em>Therefore the answer is </em></span><span><em>assure safe and healthy working conditions!</em></span><em /><span>
If you need anymore help feel free to ask me!
Hope this helps!
