Flashcards in AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS Deck (23):
1

AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS

WHAT IS THE GREATEST HAZARD AT BOTH RESIDENTIAL AND COMMERCIAL SOLAR PHOTOVOLTAIC SYSTEMS?

DIRECT CURRENT (DC) SHOCK

2

AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS

WHAT ARE MOST PHOTOVOLTAICS MADE OF?

PRIMARILY MADE OF SILICON

3

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++

4

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

5

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++

6

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

7

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++

8

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

9

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

10

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

11

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

12

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.++

13

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++

14

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

15

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

16

AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS

AT A PV SYSTEM FIRE, WHO REMOVES MODULES?

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

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?

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

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?

- 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

AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS

SHOULD COMBINER BOXES BE OPENED BY FF IN AN ATTEMPT TO SHUTDOWN THE PV ARRAY?

NO

COMBINER BOXES SHOULD NOT BE OPENED BY FIREFIGHTERS IN AN ATTEMPT TO SHUTDOWN THE PV ARRAY

20

AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS

TRUE/FALSE

PV SYSTEMS DO NOT PRODUCE ELECTRICITY AT NIGHT, HOWEVER LIGHTNING FLASHES CAN ENERGIZE THE PV SYSTEM.

TRUE

21

AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS

TRUE/FALSE

FF'S CAN CUT INTO A PHOTOVOLTAIC ARRAY.

FALSE

++DON'T ATTEMPT TO BREACH PV ARRAYS WITH HAND OR POWER TOOLS. A FF CUTTING INTO A PV ARRAY CAN BE ELECTROCUTED++

22

AUC 351 - PHOTOVOLTAIC (SOLAR PANEL) ELECTRICAL SYSTEMS

YOU HEAD OUT ON MORNING BI AND AT THE 1ST BUILDING YOU INSPECT YOUR ROOFMAN TELLS YOU THAT THE PV SYSTEM ON THE ROOF IS IN LACKING MAINTENANCE WHICH HE CONSIDERS A HAZARDOUS CONDITION. YOU INSPECT THE PV SYSTEM AND AGREE WITH HIM. WHAT IS YOUR NEXT ACTION?

- REQUEST THE RESPONSE OF THE ADMINISTRATIVE BATTALION CHIEF

++COMPANY OFFICERS ON BISP OR OTHER OUTSIDE ACTIVITIES FINDING A HAZARDOUS CONDITION RELATIVE TO A PV SYSTEM INSTALLATION THAT IS IMMINENTLY PERILOUS TO MEMBERS OR OCCUPANTS DUE TO SIZE, LOCATION, ARRANGEMENT, DEFECTS OR LACK OF MAINTENANCE SHOULD BE INSTRUCTED TO REQUEST THE RESPONSE OF THE ADMINISTRATIVE BATTALION CHIEF, CHIEF SHOULD NOTIFY DISPATCH TO HAVE DOB RESPOND++
