How many hours should a diesel tank be able to hold at full capacity for a Nursing Home with skilled care? The tank will be a base mount tank.

For a generic question, I'll give ... 90 minutes or greater.
Assuming its a Level 1 installation, from the NFPA 110 appendix:
A.4.2 Selection of the class of the EPSS should take into account past outage records and fuel delivery problems due to weather, shortages, and other geographic and environmental conditions. Class ?X? is a calculated value that usually represents between 48 and 96 hours of fuel for a Level 1 facility.
And there is also 5.1.2:
5.1.2 Seismic design category C, D, E, or F, as determined in accordance with ASCE 7, shall require a Level 1 EPSS Class X (minimum of 96 hours of fuel supply).
But that's not exactly the fuel tank capacity. NFPA 110 has other rules that relate the low level alarm and tank capacity to the generator class.

That could of been more of an engineering specification than a code requirement. If its not a 24 hour facility, then it might only need 90 min. of backup for egress lighting.
I'm thinking that the nursing home needs the longer backup because it would be very difficult (or impossible) to evacuate a nursing home.
After Hurrican Katrina, I think FEMA started suggesting even larger fuel tank capacities in areas where a disaster is likely.

so how big a tank do we need under the capitol building when the legislature is in session?
of course, if the tank exploded while the legislature was in session, maybe that would be disaster reduction........?

From the FEMA hospital design guide:
It is recommended that sufficient onsite fuel storage be provided to allow all of the facility’s emergency and standby generators to operate at full capacity for a minimum of 96 hours (4 days).15 ........
For remote facilities or situations where it is believed that refueling may not occur within 96 hours, the onsite fuel storage capacity should be increased as deemed appropriate.
15 The 96-hour fuel supply is based in part on the Department of Veterans Affairs criteria.
