An ECO depot manager must monitor the depot and ensure its safety. The system must help each depot manager fulfill this responsibility by reporting the depot status in detail.

Card 8. Depot Monitoring

depot manager	monitors depot
depot manager	wants depot status
depot governors	want to ensure depot safety compliance
depot	remains safe
depot buildings	remain safe
depot manager	requests depot status report
system	reports depot status, including:
	a vulnerable building count
	a vulnerability indicator for each building
	a drum count per hazard for each building

To ensure depot safety, the system needs to know which hazard types each storage building has been licensed to store. To minimize depot vulnerability, the system needs to know which buildings are neighbors. Thus, the system needs a map of the depot and a storage license inventory. A depot manager is responsible for supplying this information.

Card 9. Depot Map Maintenance

depot manager	maintains depot map
depot manager	wants accurate depot map
depot governors	want to ensure depot safety compliance
depot map	reflects depot building characteristics and layout
depot manager	requests depot map maintenance
system	presents depot map maintenance operations

To ensure depot safety, a depot manager must supply the system with accurate information about the depot buildings, including their locations and physical dimensions.
