Work building likely has asbestos, animals tearing up roofing. Customers and workers exposed daily. What to do?

This old warehouse I work at.. Long wait lines mean customers are spending lots of time breathing in falling debris from the roof as the birds and mice rip it apart, stuff visibly falling from the ceiling all the time due to animal activity. Is there a number I should be calling about this? Im concerned not just for myself but others... I feel like I need this tested to continue safely working here..
