(1) Their purpose is to promote the safety or welfare of the employees and authorized persons allowed access;(2) They preserve the employer's property from abusive use;(3) They are reasonably related to the purpose for which they are adopted;(4) They apply to all employees on the premises in a fair manner; and(5) They are sufficiently explicit in the prohibition, direction or limitation of the employee's conduct to fairly inform the employees of what must be done to comply.
