There are many people who are very blind but not completely so (e.g. really can’t see anything at a distance). They may be able to operate well in a lab environment.
There are people whose mental health issues are rare or can often be prevented with a service animal. Their “breakdowns” are likely not destructive anyway, so no real risk to the lab itself.
Service animals also sometimes help to warn that someone is about to have a seizure, so they can go somewhere safe.
