INTRODUCTION

For nearly half a century, our country has suffered many wars, such as the resistance war against the French colonialism and American imperialism and war to protect the northern and southwest border; land and people of Vietnam have been affected heavily by a large number of bombs and munitions used by the parties. According to statistics, only the resistance against the US, the number of bombs and munitions used by the United States in Vietnam was 15,350 million tons. Thus the estimated average amount of bombs and munitions was up to 46 tons / km2 or 280 kg / capita.

According to our summarizing documents, the percentage unexploded bombs-mines-explosive objects accounts for between 2% and 5% of the number of used bombs-mines-explosive objects, that means about 350,000 – 800,000 tons of unexploded bombs-mines-explosive objects. According to foreign document, such percentage is about 10% % of the number of used bombs-mines-explosive objects, thus the number of unexploded bombs-mines-explosive objects left over is much greater. After the end of war, there are still frequent traumatic accidents caused by such bombs-mines-explosive objects.

In the process of industrialization and modernization of the country, the removal the aftermath of unexploded bombs-mines-explosive objects lying deeply in the ground in all parts of the country in order to cater for constructional projects, land reclamation and rehabilitation, contributing to the stabilization of people's life is one of the urgent and important tasks which must be done continuously and long to ensure the absolute safety for people and the economic and national defense works of the country.

Removal of unexploded bombs-mines-explosive objects after war is the extremely difficult work which must be done by specialized forces with basic training, good technical expertise and standard equipment, scientific and strict organization in order to conduct the work effectively and safely.

...

...

...

On the basis of issued documents and the practical experiences summed up after years of implementation of the detection and handling of bombs-mines-explosive objects plus the ongoing development of technological equipment in service of detection and handling of bombs-mines-explosive objects in the country and the world.

To meet the requirements for tasks in the present period, the Ministry of Defense has issued this volume “Technical procedures for detection and handling of bombs-mines-explosive objects” replacing documents previously issued. This is the legal document defining the contents of work as well order of steps in organizing the implementation for uniform application in the tasks of Security – National defense – Economy.

Chapter 1.

CHARACTERISTICS, REQUIREMENTS AND GENERAL REGULATIONS

Article 1. Characteristics of detection and handling of bombs-mines-explosive objects.

1. Detection and handling of bombs-mines-explosive objects after war (abbreviated as DHBMEO) is particularly dangerous work with its peculiar nature of high responsibility. This is political tasks directly affecting the social order and safety, not merely as the other socio-economic activities. Only the specialised engineering forces with capability (personnel and equipment) are assigned to perform these tasks.

2. DHBMEO is difficult, dangerous and hazardous work directly affecting life and health of persons performing it, thus such persons should have particular compensation and benefits.

3. DHBMEO is done on a national scale in all different topographical types (on the ground, underwater, at sea or in rivers, lakes, midland, mountainous areas, delta, sparsely populated or urban areas ...) and in all areas affected by war.

4. Result of DHBMEO and process of implementation are directly related to the safety and life of people, assets, political security and social safety and order.

...

...

...

1. Those who perform the tasks of DHBMEO must have high sense of responsibility, absolutely control simple subjective thoughts and thoroughly comply with the technical Procedures and must not bypass or skip steps; must not chase the mere productivity which leads to performing work for form’s sake or carelessly or omitting bombs-mines-explosive objects or leading to the unsafety during the performance of DHBMEO, construction and long-term use of works later.

2. Types of machinery and equipment used for DHBMEO tasks must be of sufficient quantity as well as quality assurance. It is required to regularly test and inspect the technical conditions and replace detailes and parts that do not ensure the proper technical requirements and inconsistency (the inspection shall be done by a unit assigned by the Ministry of Defense).

3. During the implementation, it is required to test the quality of detection equipment and professional skills of technicians, works quality and compliance with the safety rules to promptly eliminate errors. The periodical testing must be done by the method of probability. Normally, the tested area is not less than 1% of total area with DHBMEO.

Article 3. Standards of detachment of detection and handling of bombs-mines-explosive objects.

a) Organized with adequate and close staff and technical equipment in line with requirements for tasks (staff and equipment with particular regulation).

b) Having adequate working protective equipment and fire and explosion prevention equipment.

4. If any unit performing DHBMEO violates the above standards and is detected by the agency or unit assigned by the Ministry of Defense, such violating unit shall be suspended its performance. If detecting any unit committing violation of 3 times or more upon request of the Engineering High Command, the Ministry shall revoke the practice license of DHBMEO.

Article 4. Classification of signal density of bombs-mines-explosive objects.

1. Concepts:

a) Signals: are all magnetic objects (or non-magnetic) lying in the ground or underground including iron, steel, shrapnel, types of bomb-mine-explosive object...which man or detectors currently used can detect them (indicated by change of sound, deflection of hand of clock, by some kinds of bar or number on liquid-crystal display regardless of size ...) and carry out the handling. The signals to calculate and prepare the performance plans and estimates (after site survey) must be the types of bombs-mines-explosive objects or magnetic objects...with their size from (30x30)mm or more lying in the ground.
