dirty dozen Flashcards
is a concept developed
by Gordon Dupont, in 1993, whilst he
was working for Transport Canada, and
formed part of an elementary training
program for Human Performance in
Maintenance.
Dirty Dozen
Poor communication often appears at the top of
contributing and causal factors in accident
reports and is therefore one of the most critical
human factor elements
Lack of communication
can be described as a feeling of
self-satisfaction accompanied by a loss of
awareness of potential dangers. S
Complacency
- The regulatory requirements for training and
qualification can be comprehensive, and
organizations are forced to strictly enforce
these requirements. However, lack of on-thejob experience and specific knowledge can
lead workers into misjudging situations and
making unsafe decisions.
Lack of knowledge
Distraction could be anything that draws a
person’s attention away from the task on
which they are employed.
Distraction
- In aviation many tasks and operations
are team affairs; no single person or
organization can be responsible for the
safe outcomes of all tasks.
Lack of teamwork
- is a natural physiological reaction to
prolonged physical and/or mental stress.
Fatigue
.
* If all the parts are not available to
complete a maintenance task, then there
may be pressure on a technician to
complete the task using old, or
inappropriate parts.
Lack of resources
is to be expected when working in a
dynamic environment. However, when the
pressure to meet a deadline interferes with
our ability to complete tasks correctly, then it
has become too much.
Pressure
.
* Being both unable to express our concerns
and not allowing other to express their
concerns creates ineffective communications
and damages teamwork.
Lack of assertiveness
There are many types of stress. Typically in the aviation environment there are two
distinct types - acute and chronic:
Stress
arises from real-time demands placed on our senses, mental
processing and physical body
Acute stress
is accumulated and results from long-term demands placed on the
physiology by life’s demands, such as family relations, finances, illness,
bereavement, divorce, or even winning the lottery
Chronic stress
- Working in isolation and only considering one’s
own responsibilities can lead to tunnel vision; a
partial view, and a lack of awareness of the
affect our actions can have on others and the
wider task.
Lack of awareness
- Workplace practices develop over time, through experience, and often
under the influence of a specific workplace culture.
