Answer to Question 1

ANS: D
Station outlets have safety valves that close automatically when an adapter is disengaged from the outlet (i.e., quick-connect adapters). The quick-connect adapters and the DISS are the two safety systems that can be at a station outlet.

Answer to Question 2

ANS: D
Figure 3-20 shows an outlet that uses DISS. This system, which was designed by the CGA, uses noninterchangeable thread fittings to connect gas-powered devices to station outlets.
