If a jurisdiction seeks special requirements from the manufacturer to ensure
that the apparatus will perform as required under local conditions, they may
be written into the bid specifications as: - ANSWER-performance
requirements.

Internal intake pressure relief valve test
When securing a detachable ladder pipe system on an aerial ladder, the hose
should be run directly up the center of the ladder rungs because: - ANSWER-
, placing the hose on either side of the center causes unnecessary torsional
stress on the ladder.

communication system on all aerial device apparatus? - ANSWER-NFPA®
1901
Which type of valve limits the pressure built up in the hydraulic system, thus
preventing damage due to overpressurization? - ANSWER-Relief valve
When it is necessary to place a firefighter at the end of the aerial device
during elevated master stream operations, the elevating platform is safer
and has: - ANSWER-more working room than the aerial ladder.
The primary difference between aerial ladder platforms and telescoping
aerial platforms is: - ANSWER-telescoping aerial platforms are not intended
for climbing.
Which interlock device prevents the aerial device from moving into regions
where it could make contact with the body or cab? - ANSWER-Body collision
interlock
Which NFPA® standard establishes the number of sections and minimum
reach required of an aerial apparatus? - ANSWER-NFPA® 1901
If multiple apparatus must work on a bridge, they should not be parked on
the same span because: - ANSWER-the combined static load may exceed the
bridge's design limitations.
Parking lots with the potential for stabilization problems should be identified:
- ANSWER-in preincident plans.
