Head protection.

You must provide, at no cost to the employee, and ensure that all employees wear a hard hat whenever there is a potential exposure to danger of flying or falling objects, unless the employees are protected by FOPS, cabs, or canopies meeting the requirements of this chapter.
(1) Head protection (hard hats) must comply with any of the following consensus standards:
(a) ANSI Z89.1-2009, "American National Standard for Industrial Head Protection";
(b) ANSI Z89.1-2003, "American National Standard for Industrial Head Protection"; or
(c) ANSI Z89.1-1997, "American National Standard for Personnel Protection – Protective Headwear for Industrial Workers – Requirements."
Note:
You may use protective helmets that do not meet these ANSI standards if you can demonstrate that they are equally effective as those constructed in accordance with the above ANSI standards.
(2) Hard hats must be maintained in serviceable condition.
