Ddas: Investigating A Metal Detector Reading, Hd-Aid

Global CWD Repository

What follows are basic procedures that you can edit and refine to suit your equipment and working preferences. They presume that deminers operate in a "One-man procedure ", with the same deminer performing all tasks during a working shift. When there is not enough equipment for each deminer to be issued with a detector and tools, two-man teams can be deployed. In a two-man team, a one-man procedure is still used. One person works while the other rests, and each individual performs all the tasks required for clearance during his/her shift.

Ddas: Crunching Data From The Database Of Demining Accidents, Hd-Aid

Global CWD Repository

In the database of demining accidents, injuries are classed as either Severe or Minor. Injuries likely to be life threatening, to require surgery or to result in permanent disability are rated as Severe. All others are rated as Minor. This distinction is for convenience and is not intended to reflect on the discomfort and/or hardship associated with the injury. In some cases, injuries were not recorded in detail but I have resisted the temptation to infer detail. Note that, in very severe injuries, only the most severe injury is generally recorded.

Ddas: Manual Demining Handtool Design Criteria, Hd-Aid

Global CWD Repository

The research I have carried out on tool development has been based on accident studies, field trials and my experience in both demining and in manufacturing in small workshops. The research led to the evolution of the following criteria and constraints. I believe that these are essential requirements when designing hand-tools for use when excavating anti-personnel blast mines. Tools used during other demining activities may not have the same requirements.

Ddas Suggested Training Uses: Management Training, Hd-Aid

Global CWD Repository

Increasingly, managers in HD are management specialists with little or no field experience. If so, they usually delegate responsibility for training and operational needs to another person, often an "Ops Manager". The manager or Ops Manager will be in charge of all training and/or refresher training, so they should read the training suggestions for deminers, paramedics and field supervisors as well as those given here.

Because the accident database is a collection of reports covering events when things did not go as planned, the examples drawn from it are usually "negative" - what not to do, rather than what to …

Ddas: Using The Database Of Demining Accidents, Hd-Aid

The author has maintained a database of demining accidents for four years. It contains records of many of the explosive accidents that deminers suffer while going about their work. This article explains the uses and limitations of the database and the software developed to contain it.

Ddas: Metal Detector Set-Up, Hd-Aid

Global CWD Repository

There must always be absolute confidence in the metal-detector’s ability to locate the target device at the required depth before Metal-detector clearance drills are applied. It is important to set-up the metal-detector appropriately for two main reasons. First it gives the Supervisors confidence that the ground can be cleared to the required depth. Second, it gives the deminers confidence that they can and will find every mine.

What follows is a basic procedure for use with all the current models of metal-detector that I know. It is intended to provide a basis that you can edit and refine to suit …

Ddas Suggested Training Uses: Paramedic Training, Hd-Aid

Global CWD Repository

The examples of medical treatment in the database are rarely well detailed. When they are, they provide examples of both "positive" and "negative" responses to accidents. some of the worst negative responses are not the responsibility of the medic - who were simply not provided with the equipment or ambulance that they need. Parts of the reports may be used in lectures or presentations or they can be distributed for critical discussion.

Ddas Suggested Training Uses: Deminer Training, Hd-Aid

Global CWD Repository

The database provides real-world examples that can be used as training aids. This will often reinforce what is considered to be common sense. Be aware that the database records prove (beyond reasonable doubt) that some commonsense wisdom is incorrect.

For example, it is a myth that the most dangerous time for deminers is shortly after their initial training. On the contrary, there is some evidence to suggest that deminers actually become more likely to have an accident the longer they work as a deminer.

Ddas: Suggested Training Uses, Hd-Aid

Global CWD Repository

The most common use of these records in training is to provide an example of what happens when things are done in the wrong way. This can be a powerful reinforcement of a lesson about doing things the right way. The database can also be a training aid for paramedics and for field and office managers.

Ddas Suggested Training Uses: Supervisor/Field Management Training, Hd-Aid

Global CWD Repository

Field supervisors or managers should also read the suggested training needs for deminers because they will often be in charge of the deminers' training and/or refresher training. When they have any training concerns, they must report this in writing to the Senior Management in order to avoid censure if accidents result from inadequate training.

Because the accident database is a collection of reports covering events when things did not go as planned, the examples drawn from it are usually "negative" - what not to do, rather than what to do. They can be useful to explain the need for rules. …

In 2015, Tajikistan became the first country to make all of its demining accident data available. Congratulations to the Tajikistan National Mine Action Centre (TNMAC), a government controlled body that has set an international standard for transparency.

Despite its popularity, and the frequent reference made to the database when updating international and national Mine Action standards, the DDAS has no formal support.

The nominal Humanitarian Mine Action industry leader is the United Nations Mine Action Service (UNMAS). UNMAS make no effort to collect and study accident records but, in 2011 when I left the IMAS Review Board, they began to …

Ddas: "Accidents" Or "Incidents", Hd-Aid

Global CWD Repository

When I started writing about demining accidents I tried to form a sensible distinction between the terms "accident" and "incident". I decided to call an unintended explosive event (or an intended explosive event that resulted in injury) an "incident". This was because an "Incident report" would be generated from which lessons that might prevent repetition of the event might be derived. I noted that the word "accident" was used for all unintended occurrences, from dropping the kettle to a car crash, but did not always apply to an intentional event that resulted in an injury. So, at that time, the …

The DDAS software was designed by me in 1998 using the Microsoft Access engine and a Visual Basic front-end. This was revised and became a relational database in 2003. The software can be used to display existing datasets or to record your own. Field names can be edited and replaced with names in another language and the content of dropdown pick-lists is easily customised. Originally distributed on CD, it is not generally given out any more but despite being dated and cludgy, it can still be used many later operating systems.

I started the Database of Demining Accidents (DDAS) in 1998 using public data gathered for the United States Army Communications-Electronics Command, Night Vision & Electronic Sensors Directorate. When they declined to publish and update the database, I did so with their tacit approval but no funding support. I did this in the hope of improving safety for deminers. The database is an easy-to use system containing the original demining accident reports overlaid with easy-search summaries.

Mine explodes when Australian military trainers were working with Cambodian colleagues 50km from Phnom Penh. An Australian and a Cambodian were killed and a second Australian injured when a landmine was accidentally detonated during a military training exercise west of Phnom Penh, Cambodia.

The primary cause of this accident is listed as a ‘Management control inadequacy’ because either the base was being used for training that the senior management did not know about or it was being used to allow tourists to fire weapons, which the senior management did not know about. Either way, the senior management failed to retain …
