An operator considering whether a quint should be used as an engine, a ladder, or both must understand that:

1. Quints can always perform engine and ladder duties simultaneously without limitation
2. Pumping water while the aerial is in service may share engine power and stabilization is required for aerial use
3. Quints exempt the crew from setting outriggers for short aerial operations
4. Quints carry no ground ladders by NFPA standard
