AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS Flashcards
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
WHAT IS THE GREATEST HAZARD AT BOTH RESIDENTIAL AND COMMERCIAL SOLAR PHOTOVOLTAIC SYSTEMS?
DIRECT CURRENT (DC) SHOCK
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
WHAT ARE MOST PHOTOVOLTAICS MADE OF?
PRIMARILY MADE OF SILICON
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
TRUE/FALSE
ON CLOUDY DAYS PV SYSTEMS CAN STILL PRODUCE ELECTRICITY, BUT NOT AS MUCH AS THEY DO ON SUNNY DAYS. PV SYSTEMS DO NOT PRODUCE ELECTRICITY AT NIGHT.
TRUE
++LIGHTNING STORMS CAN PRODUCE ELECTRICITY++
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
TRUE/FALSE
FF’S MUST AVOID WALKING ON PV MODULES SINCE THIS CAN EXPOSE THEM TO ELECTRIC SHOCK.
TRUE
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
TRUE/FALSE
ONCE POWER HAS BEEN SHUT DOWN FF CAN CUT ANY WIRE ASSOCIATED WITH A PV ARRAY.
FALSE
++FF MUST NEVER CUT ANY WIRES ASSOCIATED WITH A PV ARRAY++
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
TRUE/FALSE
ENERGIZED PV COMPONENTS SUBMERGED ON A ROOF RETAINING WATER IS YET ANOTHER POTENTIAL LIFE-THREATENING SHOCK HAZARD.
TRUE
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
TRUE/FALSE
SHUTTING OFF POWER AT THE MAIN ELECTRICAL PANEL ENSURES THAT ALL POWER TO THE BUILDING HAS BEEN REMOVED.
FALSE
++SHUTTING OFF POWER AT THE MAIN ELECTRICAL PANEL DOES NOT ENSURE THAT ALL POWER TO THE BUILDING HAS BEEN REMOVED. THIS HOLDS TRUE FOR OPENING PV DISCONNECT (ISOLATION) SWITCHES WHICH CAN BE LOCATED: ON THE ROOF, NEXT TO THE MAIN ELECTRICAL PANEL, ADJACENT TO THE INVERTER, NEARBY THE CHARGE CONTROLLER, IN THE BATTERY BANK AREA AND OUTSIDE THE BUILDING++
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
TRUE/FALSE
THE USE OF ROOFTOP DISCONNECTS SHOULD NOT BE RELIED UPON SINCE THEY ARE MAINLY INSTALLED IN ORDER TO PERFOM MAINTENANCE ON THE SYSTEM. SHUT OFF ELECTRICAL POWER TO THE INVERTED TO ENSURE POWER DOES NOT ENTER THE BUILDING FROM THE PV ARRAY CONDUIT, BATTERIES OR BACK UP GENERATOR. BE AWARE THAT INVERTERS HAVE CAPACITORS WHICH STORE ENERGY.
TRUE
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
WHAT IS THE PRIME FOCUS OF LADDER COMPANIES, IN REGARDS TO VENTILATION, WHEN ENCOUNTERING PV SYSTEMS AT FIRES?
THE OPENING/REMOVAL OF SKYLIGHTS AND SCUTTLES AS WELL AS HORIZONTAL VENTILATION SHOULD BE THE PRIME FOCUS OF LADDER COMPANY OPERATIONS
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
YOU ARE THE ROOF MAN OF L132 FOR THE NIGHT TOUR WHEN YOU RESPOND 1ST DUE TO A 2ND FLOOR M.D FIRE. UPON REACHING THE ROOF, YOU OBSERVE A LARGE ROOF MOUNTED PV ARRAY SYSTEM. WHO MUST YOU NOTIFY?
I.C. AND COMPANY OFFICER
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
IF THE PV SYSTEM IS INVOLVED IN FIRE, WHO SHOULD THE ROOF MAN NOTIFY?
I.C. AND IF IT IS GOING TO NEGATIVELY IMPACT VERTICAL VENTILATION OPERATIONS
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
L136 IS 1ST DUE TO A TOP FLOOR FIRE AT A NON FIREPROOF MULTIPLE DWELLING, THE ROOF MAN HAS JUST TRANSMITTED TO YOU THE LT THAT A LARGE PV SYSTEM IS LOCATED ABOVE THE FIRE APT AND ROOF VENT WILL BE LIMITED. WHAT ARE THINGS YOU MUST CONSIDER AS THE OFFICER SUPERVISING YOUR MEN?
- CARE MUST BE TAKEN TO AVOID COMPROMISING PV CONDUITS AND COMPONENTS INSIDE THE ATTIC, COCKLOFT AND WALL SPACES WITH HAND TOOLS
- PV SYSTEM CONDUITS CAN ALSO BE FOUND IN CLOSETS AND GARAGES
- VENTILATION FANS CAN BE USED ONCE THE FIRE HAS BEEN EXTINGUISHED
++THE INCIDENT COMMANDER SHOULD DELAY OVERHAUL UNTIL THERE IS CONFIRMATION THAT THE PV SYSTEM HAS BEEN SHUTDOWN.++
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
E287 L136 AND BATTALION 46 RESPOND TO A PV SYSTEMS FIRE ON THE ROOF OF 3908 AVE X. THE FIRE IS ON THE ROOF AND THE PV SYSTEM IS INVOLVED. AS THE ENGINE OFFICER OF 287 YOU ORDER YOUR MEN TO STRETCH A LINE TO THE ROOF. ONCE THE LINE IS ON THE ROOF YOU ORDER YOUR MEN TO OPERATE THE FOG NOZZLE SET AT 30 DEGREES FROM A DISTANCE TO EXTINGUISH THE FIRE. DID YOU OPERATE CORRECTLY?
NO
++USING WATER ON ENERGIZED PV SYSTEM COMPONENTS IS A DECISION THAT SHOULD BE MADE BY THE IC AFTER CAREFUL SIZE-UP++
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
IF BATTALION 46 ORDERS E287 TO OPERATE WATER ONTO A PV SYSTEM, HOW SHOULD THE ENGINE APPLY WATER?
- A FOG NOZZLE UTILIZED FROM A DISTANCE AND SET AT A 30 DEGRE SPRAY PATTERN IS RECOMMENDED TO PREVENT ELECTRIC CURRENT FROM TRAVELING UPSTREAM TOWARDS MEMBERS OPERATING HOSELINES.
++SIDE NOTE++
- INCIPIENT FIRES CAN BE EXTINGUISHED USING A CLASS C (DRY CHEMICAL) PORTABLE FIRE EXTINGUISHER
AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
TRUE/FALSE
STRAIGHT STREAMS USED AT A DISTANCE AND FOAM CAN BE USED ON PV SYSTEMS.
FALSE
STRAIGHT STREAMS OR FOAM SHOULD NOT BE USED SINCE THEY ARE EXCELLENT CONDUCTORS
