This book is intended not only for colleagues who work in the area of security and those who still want to know about it, but also for other areas, as everyone needs to be SAFETY and confident that they are doing their job with complete dedication and PRECISION. For in the age we are living in, the lack of sensitivity or perception of security has been aggravating disastrously, for with the uncontrollable rise of TECHNOLOGY, many are forgetting about the main, YOUR LIFE. Some clear examples of this are walking the streets with their respective CELLURARS in hand, without worrying about possible accidents, or the most frequent theft.
