When purchasing hard hats, ensure that they comply with the most recent ANSI standard. Hard hats already in use must be inspected carefully prior to use for signs of deterioration and defects.

Although OSHA does not indicate an expiration date for hard hats, some manufacturer’s do. Follow the manufacturer’s instructions regarding inspection and replacement recommendations. If an expiration date is not indicated by the manufacturer, and the hard hat is in good condition and has not been previously dropped (more than 8-10 feet) or subjected to impact, it may be used. Replacing hard hats every 5 years regardless of outward appearance is a good rule of thumb. Hard hats used in environments which have temperature extremes, sunlight, or chemicals should be replaced more frequently, such as every 2 years.
