Hard Hat Considerations

Replacing Hard Hats

Hard hat manufacturers recommend replacing hard hats at least every five years, regardless of outside appearance.

Inspect your hard hat to make sure it's in good condition.

Work under extreme conditions, such as exposure to high temperatures, chemicals, or sunlight, may require replacing hard hats after two years of use. Some manufacturers recommend replacing hard hat suspensions every 12 months. It's important to review each work site to ensure that degradation of employees' hard hats is not being accelerated due to work conditions.

Painting Hard Hats

ANSI Z89.1-2003 Appendix A4 cautions workers to be careful when painting hard hat shells since some paints and thinners can damage the shell and reduce its level of protection. It's important to consult the hard hat manufacturer before painting hard hats.

Wearing Hard Hats Backwards

Hard hats may be worn reversed if "reverse donning arrow" marking is present. A non-mandatory test protocol allows hard hat manufacturers to test the helmet and mark it with the "reverse donning arrow." This means the helmet can be worn frontward or backward in accordance with the manufacturer's wearing instructions.
