It is still considered unusual, in the grand scheme of things, for there to be disabled actors and/ or crew; and quite obviously, you cannot expect every person to know how a condition or disability may affect someone - with the results of flashing lights used by venue staff when an actor in our tour had epilepsy, or sensory things set off with no warning to the autistic cast/ crew members.
In other parts of the UK, therefore, access riders are becoming a useful document to provide to venues ahead of the tour, which provides the venue staff with the relevant information ahead of time.
For us, we state what role the person is, in the show (eg, actor, technician, etc); what the conditions are, how they affect someone, the other people in the production team who are able to assist them, and any other information, which might be like the location of specific medication, or if they need a quiet space, etc.
We have a simple Word document template now, that we fill out for each show.
NOTE - Please check with your cast and crew that any information is supplied to venues, with their permission; in line with Data Protection laws, and that the venue is registered with GDPR in turn.
