Question 5

How long must an employer retain records regarding a chemical to which an employee was exposed and for which they received medical care?

Accepted Answer

Thirty (30) years

Answer

Employers are required to retain Safety Data Sheets (SDSs) for any chemicals used in their work under the Hazard Communication Standard (29 CFR 1910.1200, as referenced in 29 CFR 1926.59). However, if a worker is exposed to a chemical and receives medical attention, the employer is still required to preserve records about that chemical for thirty (30) years beyond the date of the employee's exposure since some consequences of chemical exposure are latent, meaning they do not manifest themselves until after some amount of time has elapsed. The SDS is optional for employers to keep, but they are required by law to at the very least preserve a record of the chemical to show where and when it was used.
