FDNY Z51 Study Guide - Questions With Complete
Solutions
Engineer's Minimum Reading Log Requirement Right Ans - An
engineer needs to log readings once per shift.
Phase 2 Firemen Service Right Ans - The elevator operator is the
only person that can control the elevator.
Engineer's Responsibility with Running Machine Right Ans - If
the machine is running, the engineer should not leave the building.
Emergency Power Testing Frequency Right Ans - Emergency
power testing must be done monthly.
AB29 Certificate of Fitness Holder's Responsibility Right Ans -
The holder should inspect the battery system.
Gauge Reading for Chilled Water System Right Ans - A gauge
reading of saturation pressure of refrigerant with chilled water as

being pumped to the spaces being cooled.
, Refrigerant Escape Awareness Right Ans - In the event of a
refrigerant escape, the engineer should be aware of asphyxiation.
Chemical Fire Extinguisher and System Requirement Right Ans -
A chemical fire extinguisher and system are needed where water is
not sufficient.
Refrigerants Inside Machine Gauges Right Ans - The refrigerants
found inside the machine gauges are the same type as the
refrigerant inside the machine.

valves are used to maintain condenser pressure to a predetermined
level.
Steam Turbine Warm-up Time Right Ans - It takes 10 to 15
minutes to warm up a steam turbine.
