What happens if there is a power failure? Unless the freezer is intrinsically safe it could very well go KABOOM if it loses temperature and the compressor kicks back in.

Tissue is stored in 95% Ethanol. Even at 95% a freezer -20 or -80 is well below the flashpoint (60F). Not sure if that matters or not. I am worried about OSHA and NFPA. I think OSHA 1910 has something to say about flammables in freezers.
