Letters of Interpretation

OSHA requirements are set by statute, standards and regulations. OSHA interpretation letters explain these requirements and how they apply to particular circumstances, but they can not create additional employer obligations. OSHA letters constitute their interpretation of the requirements discussed. From time to time, OSHA updates their guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at www.osha.gov.
