1. Introduction:

A. (Security Video Main Entrance_2.5.2014.12.0.15_2.5.2014.12.0.30)
a. Mr. Apodaca, wearing a baseball hat, is seen entering the Lowes store carrying what
appears to be a four-foot fluorescent lamp in his left hand.
B. (Security Video SCO PVM 1_2.5.2014.12.5.15_2.5.2014.12.28.0)
a. Mr. Apodaca is seen in the aisle carrying the lamp in his right hand, I can see that he
moves up and down the aisle looking at what is on the shelves.
b. Mr. Apodaca changes holding the lamp in his right to left hand and back to the right
hand just before reaching up above his head with his left hand. Immediately, he can
be seen to move quickly back approximately 1 to 2 feet towards the opposite
c. Mr. Apodaca is no longer holding a lamp and a white dust/glass is seen on the floor.
Mr. Apodaca begins to move in erratic fashion forward and back, spinning around
and walking to the end of the aisle. Shortly after, Mr. Apodaca is seen holding his left
forearm with his right hand.
d. In the deposition, Mr. Apodaca states that he fell back, hit his head on the shelving,
and cut his head. In the video, at no time did I see Mr. Apodaca fall to the floor or hit
his head on the shelving.
e. Looking at the Videos, Main Entrance_2.5.2014.13.28.20_2.5.2014.13.33.0 and CS
Term 18_2.5.2014.13.27.47_2.5.2014.13.33.0, no blood can be seen on Mr.
Apodaca’s hand, however he did hold his left hand across his stomach the whole time
while standing and waiting in these videos.

2. Scope of Investigation:

My specific assignment was to review the following items,
four Lowe’s Store Surveillance Videos a through d
a. Main Entrance_2.5.2014.13.28.20_2.5.2014.13.33.0
b. Main Entrance_2.5.2014.12.0.15_2.5.2014.12.0.30
c. CS Term 18_2.5.2014.13.27.47_2.5.2014.13.33.0
d. SCO PVM 1_2.5.2014.12.5.15_2.5.2014.12.28.0
e. Deposition of Ricard Apodaca dated May 18, 2016
f. Plaintiff Richard Apodaca responses to form interrogatories
g. Incident Report and Employee Statements (Lowe’s)
h. Ballast cut sheets
i. Ballast Underwriters Laboratory (UL) listing
j. Lamp holder cut sheets and UL listing
k. Fluorescent fixture cut sheet and UL listing
In addition to reviewing the above items, I:
l. Visited the site, examined the fixture that was involved in the incident.
m. Examined the present configuration of the relocated lighting display.
n. Interviewed the Lighting Department Manager.
o. Performed voltage tests on an identical fixture and ballast.
p. Performed destructive testing to determine the voltage to ground at the lamp holder to
see if I could recreate burn marks on the test fixture similar to the fixture that was
involved in the incident.

My investigation was undertaken to determine if it was more likely than not that Mr. Apodaca could have received a shock from the lighting fixture on display and the cause if any.

Exhibit I, Video taken during test of test fixture and lamp pull out, 4 frames on 4 pages

4. Discussion:

Exhibit A, the employee statements were completed by employees who interfaced with Mr. Apodaca on the day of the incident. I value these statements because I consider all to be eyewitness reports, accurate and true.

Page 1 of 6: item 5, “Customer was pulling on the contact points of the lighting fixture
the(n) the elec(tric) arced and it shocked him.”

Page 2 of 6: “He (Mr. Apodaca) continued to keep saying ouch and hold his left
forearm. I asked if it had fallen on him and he said he was touching the display when it
electrocuted him.”

Page 3 of 6: “Customer stated he pulled back the plastic shield near where the pins
plug in on the light fixture and got a shock which threw him back causing him to drop his fluorescent tube.”

Page 4 of 6: “Customer let me know he shoked (shocked) himself on the display

Page 5 of 5: “The man told me that he wanted to check and see what type of pin was on our display fixture. He went and showed me how he grabbed it and where he grab(b)ed it was right where the bulb connects to the fixture.”

Page 6 of 6: “I ended up going back to the guy and looking at his hand he had no
marks on his hand.”

Exhibits B, C & D confirm that the ballast, lamp holders and assembled fixture, are UL Approved individually and in an assembly. UL is known for its electrical testing and safety standards in the United States.

Exhibit E, using a true RMS Volt Meter, the voltage measured from the lamp holder (lamp socket) to the grounded fixture was measured to be 355.2 volts. The ballast marking stated OCV 600V, which is the nominal voltage from lamp holder to lamp holder. This voltage was measured to be 628.1 volts; therefore, it is correctly marked.

Exhibit F, the incident fixture had unexplainable burn marks on one lamp holder.

Exhibit G, a new lamp holder before destructive testing.

Exhibit H, I duplicated the burn marks on the test fixture lamp holder. When the fixture was energized and the lamps were inserted in the lamp holders and were on, I pulled a lamp slightly out of the socket. There was an arc that was created that burned the plastic lamp holder. During this time, there was a buzzing sound and the smell of burned plastic.

Exhibit I, Video taken during test of test fixture and lamp pullout shows the arc that is caused by the 628.1 volts measured between the lamp holders.

5. Conclusions:

Based on the facts of the case that I reviewed and the electrical tests I conducted on the
test fixture and, to a reasonable degree of engineering certainty, I have the following

a. The fixture assembly in question was reasonably safe in construction, being a UL Approved assembly.

b. The fixture assembly in question was installed on a wire frame that was grounded by virtue of the fixtures on display being grounded. Each fixture on display is hung in place by two metal clips that tightly grab the wire frame, which provides additional grounding of the fixture display.

c. I conducted several continuity tests of the display while onsite: I measured fixture to fixture, fixtures to the wire frame supporting the fixtures, and wire frame to the shelving, racking and supports. All metal surfaces near the fixtures are contiguous and grounded.

d. If a fixture on display had been defective, and came in contact with the metal surface of the racking, the circuit breaker that supplies the power would trip and turn off the voltage to the defective fixture due to the grounded display system. The defective fixture would be off and safe to touch. Therefore, the fixture was not defective

e. I believe that Mr. Apodaca was shocked by the arc created when he pulled back on the energized lamp/lamp holder to see the style of pins that the lamp had. This conclusion is supported by the statements of the employees that were noted on the day of the incident. Therefore, Mr. Apodaca actions caused the shock to occur. Mr. Apodaca received up to 355.2 volts of electricity from his fingers to his forearm.

f. I believe that Mr. Apodaca reached above his head towards the fixture that was just at the extent of his reach resting his forearm on the wire racking that supported the display fixtures. Mr. Apodaca created a ground path between his forearm to his hand that contacted the arc that was created when he pulled back on the lamp/lamp holder to see the style of pins that the lamp had. Therefore, Mr. Apodaca actions caused the shock to occur. Mr. Apodaca received up to 355.2 volts of electricity from his fingers to his forearm.
