Q

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.

A

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++

Q

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.

Q

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?

A
  • 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.++

Q

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?

A

NO

++USING WATER ON ENERGIZED PV SYSTEM COMPONENTS IS A DECISION THAT SHOULD BE MADE BY THE IC AFTER CAREFUL SIZE-UP++

Q

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
  • 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

Q

AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS

AT A PV SYSTEM FIRE, WHO REMOVES MODULES?

A

THE REMOVAL OF MODULES BY FF’S IS NOT AN OPTION, THE UTILITY COMPANY AND THE LICENSED SOLAR POWER INSTALLER/ELECTRICIAN SHOULD BE REQUESTED TO RESPOND THROUGH THE DISPATCHER.

17
Q

AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS

LADDER 136 RESPONDED TO A FIRE INVOLVING A PV SYSTEM, BEING A HEADS UP STUDENT L136 CAN MAN BROUGHT A CLASS C DRY CHEMICAL EXTINGUISHER TO THE ROOF WHILE RESPONDING. THE OFFICER NOTICED THAT THE FIRE WAS IN IT’S INCIPIENT STAGE SO HE ORDERED HIS CAN MAN TO APPLY THE DRY CHEM TO THE FIRE. DID L136 OPERATE CORRECTLY?

A

YES

ICIPIENT FIRES CAN BE EXTINGUISHED USING A CLASS C (DRY CHEMICAL) PORTABLE FIRE EXTINGUISHER.

++SIDE NOTE++
ADVANCED FIRES MAY DICTATE THE LIMITED USE OF WATER IN A FOG PATTERN (30 DEGREES) FROM A SAFE DISTANCE.

18
Q

AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS

IF YOU ARE RESPONDING TO A PV SYSTEMS FIRE AND UPON ARRIVAL YOU HEAR OVER THE RADIO THAT THE FIRE IS INVOLVED IN THE BATTERIES. GOING OVER THIS SITUATION IN YOUR HEAD YOU SHOULD KNOW WHAT?

A
  • BATTERIES INVOLVE IN FIRE GENERATE EXPLOSIVE, FLAMMABLE, TOIX AND CORROSIVE GASES SO FULL PPE AND RESPIRATORY PROTECTION IS MANDATORY
  • THE USE OF DRY CHEMICAL OR FOAM EXTINGUISHING AGENTS HAS BEEN PROVEN EFFECTIVE ON BATTERY FIRES
19
Q

AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS
