Is there a maximum width between ladder rails for fixed ladders? Background for the question is I designed a steel platform to support a new equipment installation. The new platform is to be accessed from an existing platform that is 24" lower. A ladder was shown for access with a flared 24" top for a step through application with the railings narrowing for a 16" clear rung distance length. The steel fabricator showed straight rails with 24" clear rung length. I question if that was acceptable per OSHA, but accepted it after I was unable to find any reference to a maximum length of rung after spending a fair amount of time looking for it.
What I showed is a common ladder detail that I've seen and used for years, but I can't find the basis for it. Any references or insight will be appreciated.
Thanks,
