FROM. Ed Murphy, Electrical Inspector
SUBJECT: Fire Damages to a 2 -Story Single Family Residence at 10380 Castine Ave.
Owner: Peter B. Jones
On October 6, 1974 at 3:23 a.m. a fire started at the above location which created
extensive damages to the structure. Major damages took place in the garage and
spread to the residence after penetrating the roof next to the second story
structure. Damages have occurred to the roof and under floor area of the structure.
It appears from my inspection that the fire originated at or near the main
electrical panel on the servicing utility side, for the down riser that encloses
the incoming service wires shows high heat damages to the solid conduit, and the
wooden plate at this location -is completely destroyed. The incoming wiring was
aluminum with thermo-plastic insulation. Evidence in the burned panel shows all
the aluminum wiring received a very high heat and melted into a molten mass at
the bottom of the panel box.
The interior construction of the panel, including meter connection and the main
panel breaker were completely destroyed by the initial fire.
The riser became heated when the insulation melted from the wiring, and the
wiring rested against the inside of the conduit. The conduit has two burned
scars clear through the metal approximately 8 inches long and 1/4 inch wide.
Also, there is a spot burned through below the plate line on the outside of the
building.
Due to the high heat damages to the down riser by the incoming service wiring and
the completely destroyed wooden plate at the base of the main panel, there could
be reasonable assumption that a flame developed at this location and burned its
way through the structure.

SUBJECT: Fire Damage at 10380 Castine Ave.
Owner: Peter Jones
Judging from the condition of the fiberglass tub and shower enclosure, the
fire appeared to have burned down from the attic area through the wall to the
underfloor area through the PVC vent and waste lines. The heat was so intense
that it melted the solder from the joints in the copper water lines.
The fire also burned through the floor of the furnace compartment.
Apparently, the ceiling of the furnace compartment was not sheetrocked, and the
burning shingles fell into the compartment, setting the floor on fire and burning
through.
I recommend that the following items be replaced:
1. A complete drainage, waste and vent system.
2. Water and gas lines
3. Fiberglass tub and shower enclosure
4. Water heater
5. A complete new heating system.

SUMMARY
10/6/74 1515 hours. I arrived at the scene and made an inspection of the
entire structure. The dwelling is a two-story, single family dwelling containing
four bedrooms (two on the first floor. ---two on the second floor), living room,
dining room, family room, kitchen, utility room, and two and one-half baths. It
is of wood frame construction with a shingle roof.
I observed that the roof and concealed attic spaces suffered almost total
destruction in the fire. Ceilings in various rooms and hallways throughout the
house had collapsed, and the fire had extended vertically via plastic vent and
sewer piping into interior wall spaces. A visual inspection of charred structural
members underneath the house revealed that the fire had extended to this area via
a 4 inch plastic sewer pipe that had been supported in a horizontal position a few
inches from the bottom of the subflooring. Recently plastic type piping has been
installed in certain areas of dwellings in place of the more conventional but
expensive iron piping. Plastic piping as used for plumbing and venting purposes
in dwellings is highly flammable, possesses a very low ignition temperature and once
ignited, a fire will rapidly extend over its entire length. Adjacent wood structural
members will, of course, become involved. In addition to spreading fire into
interior wall spaces under the subflooring and other inaccessible areas, burning
plastic tubing emits high concentrations of carbon monoxide and voluminous amounts
of highly toxic black smoke. Fire fighting difficulties in such an environment
rapidly become compounded.
I observed where the fire had burned through the ceiling over the forced -air
heater enclosure on the first floor, dropped down, and had burned completely through
the floor in two places adjacent to the forced -air heater.
All evidence indicated the fire originated in the attached garage, northwest
corner of the structure. Inspection revealed, and the owner subsequently confirmed,
the garage had contained (in addition to the two vehicles previously described)
quantities of magnesium in various forms, flammable liquids, scrap lumber, rubber
tires, workbenches, paper, books, boxes, and other combustible material. The fuel
loading in the garage was in much greater amounts than is normally encountered in
residential fires.
There were three electrical wall outlets in the garage, and I examined each one.
No evidence was found showing that any electric cords had been plugged into the
outlets at the time the fire occurred. There was no connected electrical appliances
or other mechanical equipment, either portable or stationary, connected to any of the
outlets. Three fluorescent light fixtures were found on the floor; however, the
owner reported, and examination confirmed, that these units had not been plugged in.
Heat and flame patterns indicating direction of fire flow and degree of physical
destruction revealed the fire originated in the front (west) quarter of the garage.
At this point intense further examination placed the specific point of origin at the
northwest corner of the garage in the immediate area where the 2 inch diameter rigid
steel conduit housing the main electrical wiring pierces the concrete foundation and
mud sill and extends 45-1/2 inches to the bottom of the meter box attached to the
exterior of the garage.

I observed that the wooden eave overhang located directly over the northwest
corner of the garage had been destroyed in the fire with increasing degrees of
destruction to structural members of the eave as it extended in a southerly direction
to the opposite end (south) of the garage. Paint damage to the Volkswagon parked
in the driveway on the northwest corner of the garage was also most severe closest
to the point of origin. Flame patterns on the Volkswagon,parked adjacent to the
one just described, also indicated progressive damage most severe on the north front
side of the vehicle. The fire blocking and top double plate of the garage in the
northwest corner had been entirely consumed in the fire. Similar destruction did
not occur on the southwest front corner of the garage.
All evidence at this point clearly indicated that the fire originated in the
northwest corner of the garage, spread to the readily available combustible material
in all areas of the garage, burned through the garage roof, and extended into the
attic spaces of the dwelling itself through exterior siding, and in some locations,
burned down through the roof into other rooms of the house. A closed solid core door
from the rear (east end) to the utility room prevented the fire from extending into
the ground floor of the house in this location. I found the locking mechanism to the
wood double garage door in the debris at the front of the garage. An examination
revealed that the garage door had been closed and unlocked at the time the fire
occurred. The interior of the garage was protected with sheetrock only at the places
adjacent to the dwelling itself. Approximately four-fifths of the garage interior
was not protected with sheetrock. The ceiling of the garage was also unprotected.
It should be noted that the garage was 19 ft. wide by approximately 30 ft. in length.
I examined the 2 inch diameter rigid steel conduit pipe where it pierced the
2 in. by 4 in. wood mud sill in the northwest corner of the garage. The mud sill
on both sides of this conduit had been completely destroyed in the fire. There was
no other place in the garage where the mud sill had been completely burned through.
I examined the conduit where it had pierced the mud sill and observed where eight
holes had burned through the metal. These holes had blown through the interior of
the conduit to the exterior adjacent to the mud sill and other pieces of scrap lumber
that the owner subsequently reported he had stored in that location. One of these
holes was 7-1/4 in. long by approximately 1/4 in. wide, and the others were of various
smaller sizes. One of the holes had actually blown out through the concrete facing
on the exterior foundation below the meter box. The only possible way these holes
could have been produced was as a direct result of massive electrical arcing, sparking,
and short-circuiting occurring on the interior of the conduit. Arcing and sparking
of this magnitude will produce temperatures well in excess of 3,000 degrees. A
visual inspection of the interior and exterior of the electric panel box revealed
physical evidence indicating a virtual total blowout of all interior component parts
including the main circuit breakers, aluminum wire connectors, and neutral bar.
The interior and exterior of the metal box itself indicated that extremely high
temperatures were produced within the interior of the meter box. The physical condition
of the interior and exterior of the meter box is entirely inconsistent with a fire
originating on the exterior with flames impinging on the box itself. Evidence at this
point indicated that an electrical malfunction had occurred on the interior of the
meter box and had been reflected to the wiring on the interior of the conduit where
massive electrical shorting had also occurred in addition to the short-circuiting
that occurred on the interior of the meter box itself.

I eliminated any other possible source of ignition in the immediate area of
origin including,but not limited to, careless smoking, a burning candle, an accidental
explosion, or the possibility of a deliberately set fire.
I examined the fuse box located in the southeast corner of the garage, and
although fire destruction was extremely severe on the interior of the fuse box,
visible evidence indicated that all of the fuses were in the "On" position.
Considering that all evidence at this point indicated the electrical malfunction
occurred in the meter box itself, the house fuses all being in the "On" position
would not be significant. I observed that the clock attached to the range in the
kitchen had stopped at 3:21. It can reasonably be assumed that this was 3:21 a.m.
STATEMENTS: 10/6/74 - 1630 hours. I interviewed MR. PETER JONES, the owner
of the property. MR. JONES is employed as an electrical engineer at PHILCO-FORD
CORPORATION, Palo Alto. 14R. JONES confirmed the location of various items and
articles that had been located in the garage. He reported that in the northwest
corner of the garage adjacent to the 2 inch conduit leading to the electric meter
box, he had stacked in a vertical position numerous pieces of wood and lumber in
various sizes including 1 in. by 1 in., 1 in. by 4 in., 2 in by 4 in., and 4 in by
4 in. plus other pieces of scrap wood. He worked on automobiles and racing cars as
a hobby and had numerous tools and vehicle spare parts stored in the garage.
On the evening prior to the fire his sixteen year old son, MICHAEL, was the last
person in the garage. Sometime between 1930 hours and 2000 hours, MICHAEL had opened
the garage door and placed his bicycle in the front portion, south side of the garage.
He then closed the garage door down but did not lock it. MR. JONES reported that he
had not worked in the garage for at least one week because he had not been feeling
well. His eight year old daughter, SUSAN, had gone to bed shortly before 2300 hours
on 10/5/74, and MICHAEL had gone to bed at approximately 2300 hours. MR. JONES had
placed a load of laundry in the electric dryer located in the utility room at
approximately 2300 hours just prior to going to bed. The drying cycle was 90 minutes,
indicating that the electric dryer should have shut off at approximately 0030 hours,
10/6/74. Both of his children slept in the bedrooms located on the second story,
and he was asleep in the master bedroom located on the first floor. He was awakened
by the sounds of "popping and crackling", and when he ran to the living room window
and looked out, he observed flames coming out from the front of the garage. The fire
had not yet broken through the garage roof. He ran upstairs, woke his children up,
and removed them outside to a place of safety. He then tried to use the telephone to
notify the fire department; however, the line was dead. He also mentioned that at
the time he woke up, all of the electric power was off in the house. He then ran
outside and clearly observed that all of the flames appeared to be concentrated in
the front portion of the garage and were extending to the exterior over the front eave
area of the garage. He then rolled both of his Volkswagons parked in front of the
garage down into the street.
MR. JONES mentioned that in the past few months, the lights in the house had
dimmed on a few occasions; however, they never went completely off, and no circuit
breakers were tripped. It should be noted that subsequent to obtaining this information
I learned that a dimming of the electric lights can sometimes be attributed to a loose
neutral wire connected at the meter box.

10/6/74 - 1700 hours. I interviewed MR. SHEL SCHUMAKER, the occupant of the
residence located on the south side of the JONES home. MR. SCHUMAKER told me that
he was in bed at the time the fire occurred. He was awakened by the sound of
crackling and glass breaking. When he looked out his window, he observed that the
entire front side of MR. JONES' garage was on fire. The fire had not yet broken
through the garage roof. He ran outside and tried to help MR. JONES in whatever
way he could prior to the arrival of the fire department. He heard no unusual
noises prior to his discovery of the fire. He had no further information.
10/6/74 - 2000 hours. I contacted the Reporting Party, MRS. JACKIE GALLAGHER,
by telephone at her residence. It should be noted that the GALLAGHER residence is
located on Chisholm Avenue, the first street west of the JONES residence. Their
home is slightly elevated from the JONES' house and is roughly in a direct line of
sight in that the back of the GALLAGHER residence faces the front of the JONES
residence. MRS. GALLAGHER told me that she and her husband were asleep in their
back bedroom when they were awakened by the sound of glass breaking and the crackling
sounds of the fire. They looked out their bedroom window and observed large amounts
of flame coming from the direction of the JONES residence. She immediately called
the fire department. She had no additional information.
On 10/7/74, I interviewed MRS. AUDREY CREW who lives directly across the street
from the JONES residence. She had been asleep in the rear bedroom of her house when
she was awakened by the sound of an "explosion." She got out of bed and observed the
fire burning over the entire front portion of the JONES' garage door. The fire was
extending up over the eaves but had not yet broken through the garage roof. She
also observed a Sheriff's Office Patrol Unit parked in the middle of the street in
front of the burning house and assumed that the officer had already radioed information
of the fire. She heard nothing unusual prior to being awakened by the sound of what
she described as an "explosion". It should be noted that the sounds of "explosions",
glass breaking, and other unusual noises are entirely consistent with a large fire
burning in a structure. These sounds are produced by hot expanding gases, exploding
aerosol containers, breaking windows, and falling debris.
10/7/74 - 0930 hours. I arrived at the JONES residence and continued my
inspection of the burned area with particular emphasis at the point of origin. Shortly
after my arrival, MR. ED MURPHY, Cupertino Electrical Inspector, also arrived on the
scene. At this time, a possible hazardous condition was noted at the JONES residence
in the,form of an extremely long ground wire originating at the meter box and extending
up the northwest corner of the garage over the entire front portion of the garage and
terminating near floor level on a copper water pipe in the southwest corner of the
garage. The water pipe in this location did not go to ground but instead ran the
entire length of the garage and went into the house. It later terminated in an iron
pipe on the southwest corner of the dwelling at least 75 ft. from the panel box.
At this point the iron pipe penetrated the ground and extended toward the street in a
westerly direction. It is considered safe practice to terminate a ground wire as close
as possible to the electric meter box.
At this time it was confirmed that the electrical service to the house was 220 volts,
100 amperes. Four conductors of #4 A.C. aluminum 7 -strand wiring had been connected to
the meter box. The entire remaining contents and debris of the meter box were examined
at this time, and the possibility of loose aluminum wiring connectors was readily
apparent.

It could be assumed that if a problem had developed at the neutral conductor
in the panel box, it would have tried to go to ground through the normal channel
as previously described. If the ground was faulty or ineffective, the neutral wire
would continue to heat in excessive and progressive degrees until the plastic type
insulation on the wiring coming into the panel box through the underground conduit
shorted out directly against the surface of the conduit itself. This situation would
have resulted in massive arcing and sparking, blowing holes through the conduit and
immediately igniting any adjacent combustible material. At this time no other possible
source of ignition could be found. The physical evidence contained in the meter box
was secured as evidence. Numerous photographs were taken of the entire scene.
10/8/74 - 1200 hours. I met three other private fire investigators at the scene,
including a recognized electrical wiring expert. All possibilities were considered,
and as a result of our thorough inspection and examination of the scene, it was
determined that the only possible cause for the fire could have been an electrical
malfunction originating in the electric meter box. The electrical current,seeking a
path to ground, was unable to overcome the resistance in the lengthy ground wiring
and returned to the source in the meter box. The wiring and wiring insulation
immediately began to overheat, eventually melted off the insulation, and the bare
wires grounded on the interior of the conduit creating the massive arcing and sparking
as previously described.
It was confirmed at this time that the dwelling was approximately five years
old and that MR. JONES was the original owner. He had not experienced the light
dimming problem until the past few months.
10/8/74 - 1500 hours. An intense examination of all of the remaining parts
found in the meter box, including the aluminum wiring connectors, pieces of the wiring
itself, and main circuit breakers, was undertaken. Definite signs of short-circuiting
were observed in the aluminum wiring connectors.
It was confirmed at this time that the fire did, in fact, originate in the main
electrical panel box. The electrical power tried to seek a path via the main ground
that terminated approximately 75 ft. away from the panel box. The resistance could
not be overcome, and the problem continued to progress within the panel box itself.
Massive short-circuiting occurred within the box itself and the 2 in. rigid steel
conduit at the mud sill level of the garage. Readily combustible material located
immediately adjacent to the massive arcing and sparking in the conduit ignited
immediately and eventually spread throughout the interior of the garage. It is assumed
at this time that the entire situation was probably initiated as a result of the drain
on the electric service as a result of the electric dryer that was in use prior to the
fire.
Physical evidence indicates that the fire probably burned for a period of
approximately twenty or thirty minutes prior to its discovery.
Evidence indicates that the problem could have been prevented in two ways: (1) By
insuring that the electrical system was properly and adequately grounded according to
normal safe practices. (2) By insuring that the metal connectors for the stranded
aluminum wiring were adequately tight. It is generally accepted that loose connectors
for stranded aluminum wiring are one of its major deficiencies.

1. PETER JONES - Owner/Occupant
F-74/5-181
Alarm No. 7615
Sunday, October 6, 1974 - 0430 hours. At the request of Central Fire District,
I responded to investigate a fire which occurred at 10380 Castine Avenue, Cupertino.
When I arrived at the scene, I contacted Central Fire District's Battalion Chief
HUGH TURNER who was in charge of fire fighting operations. Central Fire District's
firemen were in the process of extinguishing a fire in a two-story, single family
dwelling located on the east side of Castine Avenue near the intersection of Rumford
Avenue within the city limits of Cupertino. The temperature was in the mid-50 degree
range, and there was no appreciable wind at that time of the morning. The dwelling
was approximately five years old and was of conventional construction, that is a
Type V (combustible) --- N (Nonrated) ---0 (Ordinary) which was a wood shingle roof ---S
(Stucco) exterior siding. At the time of my arrival the entire roof of the garage which
juts out from the front of the house nearest the street was completely burned away. The
fire had extended into the dwelling part of the building through communicating
openings from the garage into the dwelling part. Although the garage was loaded with
debris from the fire, such as: sections of the roof, etc., I could see that there were
numerous combustible items such as: vehicle tires; two vehicles, one a 1958 Porsche
Speedster, the other a Formula V race car; the remains of large stand-up roll type
tool boxes; bicycles; and many other combustible and noncombustible items. The burn
patterns in the garage at that time indicated that the fire probably started near the
front of the garage as this is where the greatest amount of damage was. This was further
substantiated by the fact that the damage and burn patterns and depth of char on wood
surfaces diminished as it went towards the dwelling. The entire garage door (the main
garage door) was completely burned away. However, from the position of the metal arms
that control the door, it appeared that it was in the closed position at the time of
the fire. Burn patterns in the front part of the garage also indicated there was
heavier destruction in the northwest corner area where the electrical service came in
from the street. There was a utility junction box at that point, and then the electrical
service went from the top of that box overhead through a conduit to the circuit breaker
panel on the other side of the garage. The electrical utility service was brought to
the house via underground conduit. There were two automobiles parked in the driveway
facing the garage. The burn patterns on these automobiles, which suffered moderate
heat and smoke damage, indicated the fire came from the north side of the garage
towards the south. In other words, there was more damage on the north edge of the
automobiles, and the degree of damage diminished as it went in a southward direction.
A thorough search of the garage area at that time failed to reveal any indication that
the fire was of incendiary origin.
Contacted MR. JONES, the Owner/Occupant, at the scene. He and his two children
were home at the time of the fire. His wife was recuperating from recent surgery, and
because he had a cold, she was advised not to stay at the house and consequently was
staying with friends. He went to bed at approximately 2300 hours on Saturday night,
October 5, 1974, and his son, age 13, and daughter, age 8, had gone to bed before
that. He was awakened by popping noises, and upon looking out the windows, he saw flames
coming out of the front of the garage. He alerted his children, and they managed to get
out of the house safely. His hobby is working on automobiles and race cars. The Porsche
belonged to him and had been in the garage for several years. The Formula V race car,

SUPPLEMENT - Page 2
which is a small vehicle powered by a Volkswagon engine, belonged to a friend of his,
and he was working on the vehicle getting it ready for races. The Formula V race
car had a fiberglass body and was located near the northwest corner of the garage.
The Porsche was in the southeast part. He had not done any work on either of the
vehicles for at least one week prior to the fire. No one uses the garage except
himself and his children whc store their bicycles in the garage. He figured the Porsche
was worth between $6,000 and $8,000, and the Formula V race car was worth approximately
$3,000. He also had a great many expensive precision tools and other equipment in the
garage. There were also some other internal combustion engines, some of them containing
various amounts of magnesium including some of the wheels which were stored in the
garage. He kept most or all of his flammables in locked garbage cans at the side of
the house. I did see these cans, and they were strapped and locked. Both he and his
wife are non-smokers, and he does not believe that either of his children smoke. The
last time anyone was in the garage was when his son put his bicycle away early Saturday
evening. He was sure that no one was in the garage after that. MR. JONES is an
electrical engineer at the Philco-Ford Company. He stated that to his knowledge
he did not have any enemies or anyone mad enough at him to have reason or want to burn
his home. He has had a few neighbors who were a little concerned with his avocation
but would not be mad enough to burn his house. One of the neighbors who was a little
upset about it had moved away several weeks before the fire occurred.
The follow-up investigation was performed by DFM RUSSELL KUEBEL of the FMO. See
his report for additional details as to the origin and cause of the fire.
