Flammable Liquids questions for the ASP

Question 1

A site is adding a remote pumping system for gasoline (a Category 1 flammable liquid) to feed three dispensing units. During a pre-startup review, the safety professional checks the control arrangement. The electrician reports that the pump is wired to a single key switch in the station office. Once the attendant turns the key, the pump runs continuously and supplies all dispensers until the key is turned off at the end of the shift. Impact valves with fusible links are installed at the base of each dispenser. What is the required corrective action?

1. ANo correction is needed, because impact valves with fusible links at each dispenser provide the required protection against uncontrolled flow.
2. BReplace the key switch with a control that lets the pump run only when a nozzle is removed from its bracket and the dispenser switch is manually actuated, and that stops the pump when all nozzles are returned.
3. CKeep the key switch but add a timer that shuts the pump off after 30 minutes of continuous operation.
4. DRelocate the pump inside the station building so the attendant can control it directly from the office.

Question 2

A facility keeps flammable liquid drums on an outdoor pad next to its warehouse. The pad is surrounded by a 6-inch curb with no outlet. After storms, rainwater stands inside the curb and the drums sit in it. The safety manager must fix this without weakening spill protection. Which corrective action fits the standard?

1. ACut a permanent opening in the curb on the warehouse side so rainwater and any spills run off freely
2. BConnect the pad to the warehouse's interior floor drain, with the valve key kept in the office
3. CInstall a drain from the curbed area that ends at a safe location away from the building and can be operated from a protected spot during a fire
4. DKeep the curb sealed and pump out the water with a portable pump after each storm, when staff have time
