[Note:
there were records of 280 accidents in the DDIV when this paper
was written. There are now over 1000, and the general inferences
over hand-tools that can be derived remain substantially unchanged.
The DDIV later became the DDAS.
An
analysis of incidents that have occurred to date in Humanitarian
Demining (HD) was completed in the Summer of 1999 using the
AVS DDIV - a software database recording the details surrounding
over 260 incidents around the world. While it is not possible
to be certain how many incidents went unrecorded or were concealed
it is believed (with the exception of Afghanistan) that almost
all of the HD incidents that have occurred in the countries
covered are detailed. (For Afghanistan, all incidents over more
than two years are covered, but the data before that time is
not detailed enough to be useful so those incidents were deliberately
omitted).
That
database is now accepted by many HD professionals as a useful
resource in determining risk and assessing protection needs.
(It has been accepted as an authoritative resource by the User
Focus Group advising GICHD - and ultimately UNMAS - when determining
protection needs in humanitarian demining.)
The
DDIV records the most common activity at the time of an injurious
incident as “Excavation”. An excavation incident
is defined as happening: “when an incident occurs while
a deminer is investigating a detector reading or digging in
a suspect area with any tool”. This includes those occasions
when a deminer may be “prodding” or using a trowel,
a bayonet, a pick or a shovel - any action involved in uncovering
an object that is being investigated in case it is a mine.”
Ignoring
“missed-mine” incidents - where the deminer steps
on a mine that he or his colleagues have failed to locate -
“excavation incidents” occur with almost four times
the frequency of the next most common incident (which occurs
while “handling” a device).
There
is evidence in the DDIV of inadequate tooling with tools breaking
up and/or encouraging vertical excavation. At least five deminers
have died as a result of their hand-tool (or parts of it) hitting
them. In more than half of excavation accidents, severe hand
injury occurred including the amputation of fingers or entire
hands. In additional accidents the victims lost lower or upper
arms. There is also evidence among the records that safety can
be enhanced by using long tools, hand-shields and sensible manufacturing
constraints. For example, in more than quarter of excavation
accidents a long, shatter-resistant hand tool was used, and
is it likely that its use reduced a deminer’s injury by
keeping his hand at a distance when he detonated a mine during
excavation.
Leaving
aside the injuries to the eyes, face and head, excavation incidents
lead to the following severely disabling injuries (in order
of frequency): severe hand; severe arm; amputation of finger(s);
amputation of an arm; amputation of a hand.
From
an analysis of the tooling used at the time of the incident
and of the activity taking place, it can be determined that
long hand-tools that do not disintegrate in the detonation are
safer to use than short hand-tools or tools that separate or
shatter.
[Obvious
really, but the full paper details the evidence in the hope
of silencing those who defend the convenience of buying off-the-shelf
building and gardening tools.] See safer tool designs.
