ST. CLOUD -- The St. Benedict's Senior Community along with St. Cloud Hospital will hold a mock disaster tomorrow.

The drill will test how well the St. Benedict's and hospital staff are prepared to handle a large-scale evacuation of elderly residents.

The scenario for the mock disaster will be a nearby train derailment that has released chlorine gas into the air, prompting the evacuation. If you see emergency vehicles, triage tents and people with what appear to be injuries, don't be alarmed, it's only a drill.

The mock disaster will be from 1:00-to-4:00 p.m. at both the St. Benedict campus and St. Cloud Hospital. The exercise won't impact normal operations at either facility.
