Combiner boxe_____be open by FF’s, in attempt to shutdown the PV array?

A

SHOULD NOT BE OPENED BY FF’S

22
Q

Wires running from the array to the power distribution system, should ALWAYS be considered ?

A

LIVE, unless there is a disconnect on the PV array itself

23
Q

On buildings with sloped roofs/PV arrays will generally be installed on …?

A

SOUTH AND WEST FACING SIDES

24
Q

When FF’s are working in close proximity to a PV system…?

A

SAFETY OFFICER should be assigned to the roof

25
Q

Company Officers on BISP, or other outside activities, finding a HAZARDOUS condition relative to a PV system, that is IMMINENTLY PERILOUS TO MEMBERS OR OCCUPANTS DUE TO SIZE, LOCATION, ARRANGEMENT, DEFECTS, OR LACK OF MAINTENANCE, should?

A

request the response of the ADMINISTRATIVE BC

26
Q

Buildings with PV systems should be…?

A

entered into CIDS

27
Q

A 
PV array on roof
limited roof ops
pv disconnects located at
batter storage system located
backup generator located
installer contact number
28
Q

All electrical PV array systems should be treated as…?

A

ENERGIZED

they do not turn off by flip of a switch

29
Q

Integrated design…

A

serves as structural element (roof, wall, canopy or skylight) and REDUCES concentrations of added weight

30
Q

Flush Mounted…

A

used with SMALL solar arrays and PEAKED roofs

31
Q

Stand mount systems must be installed to..?

also known as UNIVERSAL mounting

A

withstand loads…used with LARGER solar panel systems

32
Q

withstand loads…used with LARGER solar panel systems

33
Q

The IC should delay overhaul…?

A

until CONFIRMATION that PV system has been shutdown

34
Q

The IC should delay overhaul…?

A

until CONFIRMATION that PV system has been shutdown

35
Q

Cells…

A

photovoltaic cell is the device that converts the sun’s light energy into electricity by means of the photovoltaic effect

36
Q

Module…

A

a module (solar panel) is an interconnected assembly of photovoltaic cells…cells are arranged in a grid like pattern on the surface of the module

37
Q

Array…

A

modules in a PV array are normally first connected in SERIES to obtain correct voltage for the system (residential 600 volts are common)…individual leads are then connected in PARALLEL to allow system to add more amperage

38

PRIME FOCUS of LADDER OPS…

A

opening/removal of skylights and scuttles, as well as horizontal ventilation

41
Q

PRIME FOCUS of LADDER OPS…

A

opening/removal of skylights and scuttles, as well as horizontal ventilation

42
Q

FF’s discovering PV arrays at fires and EMERGENCIES should IMMEDIATELY NOTIFY…

A

their Company Officer and IC for relay to all members

also, Inform IC if PV system is involved in FIRE and if it will negatively IMPACT VERTICAL VENT. OPERATIONS
