One of the early MRM training programmes, developed by Gordon Dupont for Transport
Canada, introduced "The Dirty Dozen", which are 12 potential problem human factors areas.
A series of posters have been produced, one for each of these headings, giving a few examples of good practices which ought to be adopted, or "safety nets". These are summarised as follows:
1. Lack of communication Use logbooks, worksheets, etc to communicate and remove doubt.
Discuss work to be done or what has been completed.
Never assume anything.
2. Complacency Train yourself to expect to find a fault.
Never sign for anything you didn't do [or see done].
3. Lack of knowledge Get training on type.
Use up-to-date manuals.
Ask a technical representative or someone who knows.
4. Distraction Always finish the job or unfasten the connection.
Mark the uncompleted work.
Lockwire where possible or use torqueseal.
Double inspect by another or self.
When you return to the job, always go back three steps.
Use a detailed check sheet.
5. Lack of teamwork Discuss what, who and how a job is to be done.
Be sure that everyone understands and agrees.
6. Fatigue Be aware of the symptoms and look for them in yourself and others.
Plan to avoid complex tasks at the bottom of your circadian rhythm.
Sleep and exercise regularly.
Ask others to check your work.
7. Lack of parts Check suspect areas at the beginning of the inspection and AOG the required parts.
Order and stock anticipated parts before they are required.
Know all available parts sources and arrange for pooling or loaning.
Maintain a standard and if in doubt ground the aircraft.
8. Pressure Be sure the pressure isn't self-induced.
