Ground Crew Safety Reprise
The August 1999 CALLBACK contained an article about a
baggage handler who went to sleep in an airliner cargo
hold and awoke at FL200. His banging in the cargo hold
was heard by the cabin crew, and the aircraft made an
emergency landing. But what happens when the cries for
help of a cargo hold occupant can’t be heard? As this First
Officer’s report concludes, the occupant may be lucky to
survive:

I was the First Officer on a cargo/mail flight from XXA
to XXC, with a 16-minute stop in XXB. The first leg was
flown at FL310 and the second leg at FL270. During postflight
duties at XXC, our company mechanic came to the
cockpit and advised there was a foreign national in our
aircraft cargo compartment, cold but alive, stating that he
was a company employee that had been closed in the
aircraft belly compartment in XXA. Maintenance also
advised the airport security and an ambulance were
enroute..
The man appeared cold but otherwise OK. He said he was
waiting in the aft belly for cargo to be loaded. No cargo
arrived. The door was closed. Due to the ramp noise,
hearing protection, and the APU I can only assume no one
could hear his cries and knocking for attention. It is the
responsibility of the loading crew to look inside the
compartment before closing the door… It is my
understanding that my company and the FAA are looking
into ways to prevent this from happening again… If this
had been a much longer flight, I am sure it could have been
fatal. As it was, the man was closed in the compartment
for a total of 2-1/2 hours; 1/2 of that [time] was in flight.
Clip-on badges or flags of a distinctive color, attached to
the cargo conveyer belt, would be an effective way of
signaling that the cargo hold was occupied. Removal of
the badges/flags could be a ground crew check item.
More on Battery Fire Hazard
An article in the October 1999 CALLBACK on battery fire
hazard has created a ripple of interest, and several letters to
the Editor. We’d like to share excerpts from this
correspondence with readers who may carry spare batteries
in their flight gear or personal belongings. We begin with a
pilot’s tale of a battery EXPLOSION in flight:
✍ Just wanted to reinforce the problem with carrying
batteries with unprotected terminals as described by the C-172
pilot in the Oct. 1999 CALLBACK.
I was climbing out on takeoff years ago in a C-182 when I
heard a sharp explosion. Turned around and saw a cloud of
light smoke in the baggage compartment.
I thought the aircraft battery had exploded but alternator
output, etc. were normal. Immediately returned to airport,
landed, and removed everything from baggage compartment.
After checking aircraft battery, began to empty luggage, etc.
Finally found the remains of the culprit in my flight case. I
was using a portable intercom at the time and had changed
batteries (9V alkaline) just before engine start and had thrown
the “discharged” battery into my flight case for disposal at
home. It had shorted out on a metallic piece of the flight case
and had exploded, apparently due to the ignition of a gaseous
by-product of the shorted condition which accumulated in the
flight case…
If this explosion had occurred in a pocket, it could have caused
serious injury. My wife is a Registered Nurse, and was in the
habit of carrying spare batteries for pacemakers, etc. around
the hospital in a pocket with coins, keys, etc. Needless to say,
she immediately stopped that habit.
When we carry 9V alkalines
now, they not only have a
terminal protector in place, it
is also held on with rubber bands.
Hope this word of caution helps keep
the skies (and our bodies) safer.
Another reader adds a domestic note on battery-related “hot
pockets” that has implications for many light-airplane pilots–
and their passengers:
✍ Recently, I was changing the batteries in my home smoke
alarms, and upon removal of an old battery, I put it in my
pocket... In short order I realized that I had a “hot pocket”… I
reached into my pocket to remove the hot material and
discovered the old battery, which was very warm. I then
realized that it had shorted out upon contact with either the
foil of my life savers or the steel in my pocket knife…
Being a pilot, your article alerted me to the fact that I must
now treat batteries with special respect while having extras
aboard...
A summary of these battery care “life savers”:
✔ Use terminal protectors on all batteries carried onboard
