The same applies. Adult films are subject to at least some regulations, and that mechanism would still apply for something like hazard pay. But, as I mentioned above, you don't necessarily need an industry standard when the its a similar mechanism as another industry (such as the film industry as a whole) because industries that are not specifically regulated fall under general OSHA regulations. What constitutes a hazard in this pandemic isn't dependent on the industry, it's dependent on the situations.
