Is an air cast considered medical treatment by OSHA?

Yes, an air cast can be considered a form of medical treatment under OSHA regulations, as it is used to support and protect an injured limb. OSHA defines medical treatment as any treatment other than first aid, and since an air cast typically requires a healthcare professional's prescription and is intended to manage a specific injury, it falls under this definition. Thus, if an employee requires an air cast due to a work-related injury, it would be considered a medical treatment event.
