Explosive Detection Equipment

When you begin to look at what exist for explosive detection equipment these days there are two distinct groups and types of equipment that you can choose from. The first are the set of electronic and other mechanical devices that use technology to detect the presence of explosive materials, the second are animals and other “natural” ways of detection. These typically will include dogs as the primary method for detection. These two methods are not mutually exclusive of each other and can be used most effectively in conjunction. By combining these two methods of explosive detection the law enforcement or other agency can be most effective in their detection methods. Read on to see how these two can work together.

Airport Explosive Detection

Electronic detection is extremely accurate and does a very good job of picking up and detecting explosives without fail. When you compare electronic equipment with natural equipment, you can immediately see that it is far more predictable and reliable. You do not have to motivate or reward a sensor that can detect chemicals in the air. This equipment is always working at a very predictable rate if it is well maintained and monitored. The downfall of this is however generally speaking the equipment may not be able to tell you if there is something wrong with it. Because of this you need to be constantly vigilant to run tests on the equipment to make sure that is performing within very specified boundaries.

A major negative of the equipment is that in general is that it is not mobile. Scanners are a great tool and sniffers can pick up a wide variety of chemicals that are used in bomb making and manufacturing. These scanners will detect a certain amount of the chemical in the air and send an alert to let you notice it presence. However since these units are not mobile, the bomb and chemicals must pass through it to get detected. Many times they are also obvious and can be avoided. These detectors work very well in airports and other controlled locations where you want to check people going in and out, but do not do a good job in open and free moving areas.

Airport Explosive Detection

All you need to do to see how much the world has changed since 9/11 is to visit any airport. It doesn’t need to be an airport that deals with international flights, it can be an airport that just deals in local traffic, but you are bound to see all of the changes that have been implemented to try and increase the security associated with air travel. But it is not just the airports that are affected by all of this heightened security, there is a ripple effect that brings new technology to our society and new business to those companies that create that new technology.

An airport used to be a place you would go for one of three reasons. You were either getting on a plane to go somewhere for either business or pleasure. You were going there to meet someone who had just come in on a plane for either business or pleasure. Or you just like watching planes land and take off at the airport and every once in a while you like to get away from everything and hang out at the airport. But lately there is a whole different type of person who spends a great deal of time at the airport. Ever since 9/11 there has been a large increase in government, and private sector, spending on new ways to stop terrorism. Just saying that you want to stop terrorism is an incredibly broad statement. What you need to do is identify what you need to stop in order to make the airport safe. This is where the field of airport explosive detection has come into play and has caused an entire industry to develop and grow around it.

Airport Explosive Detection

It used to be that airport explosive detection was done one of two ways. Either someone overheard you saying something about a bomb or an explosive sniffing dog found something in the baggage that caused your flight to be delayed. Beyond that all the airport screeners really had was the x-ray machines that look into baggage as people check in and that was not always reliable. Ever since the terrorist attacks it has become a prime importance to find new and effective ways to detect explosives to protect people from the possibility of terrorist attack. From this comes a new interest in screening technology that may not have been a huge priority in the past. Companies that had new technologies that they could not get funding for are suddenly finding themselves to be very popular and having access to all the working capital they need.

New technology is usually driven by a need. Ever since people decided that they needed to be more safe when they fly the explosive detection industry has seen a large increase in activity. The hope is that we will someday get to the point where dangerous explosives are detected in an instant and the people that try to bring them on to a plane are caught and punished. Until the technology is advanced and the explosive detection industry grows sufficiently we will still have to wait for these new advances to come while still relying on the old ways to keep us safe while we fly the airlines and get from place to place. Today there is a lot more focus on being more efficient in detecting dangerous explosives but without new technology there is always the chance that something could go very wrong.

EXPRAY Explosives Detection Kit

Expray is a unique, aerosol-based field test kit for the detection and identification of Group A explosives (e.g. TNT, TNB, etc.), Group B explosives (e.g. Semtex H, RDX, C4, etc.) and compounds containing inorganic nitrates that are used in improvised explosives (e.g. ANFO). Expray is commonly used as a pre-blast, analytical tool, post-blast investigative tool, screen against potential terrorist elements and as a technical evaluation test in soil remediation on hazardous material "clean-up" sites. When used as a post-blast investigative tool, the product is field proven to speed up crucial investigations. The level of sensitivity (20 nanograms) surpasses that of other currently available products.

EXPRAY Explosives Detection Kit

The testing process is fast and efficient. No glass ampoules, spatulas or waiting period required. Results appear in seconds. No additional tools or equipment required. The identification/detection process requires no special training and testing can be performed "on the spot". For both law enforcement and investigative personnel, Expray is a proven tool for increasing the accuracy, efficiency and number of interdictions. For forensic and environmental laboratories, it has proven to reduce the number of samples submitted for testing, saving both time and money. Expray is sold in a kit configuration, which provides all three aerosol sprays, collection papers, and an RDX-impregnated verification pad (verification pad is useful for ensuring that the spraycan still contains active reagents and for demonstrating how a positive reaction will appear) in a convenient plastic carry case. Expray kits are available in both regular size (100 tests) and mini-size (50 tests). Mistral is proud to say that Expray provides a low "per test" cost and poses no risk to you or the environment "E": Expray-1 for Group A Expray-1 is used to search for GROUP A type explosives which include TNT, Tetryl, TNB, DNT, picric acid and its salts. To use, wipe suspected surface with special collector test paper. Spray with Expray-1. If a dark brown-violet color appears, this indicates the presence of TNT; An orange color indicates the presence of Tetryl and other GROUP A explosives. "X": Expray-2 for Group B Expray-2 is used to search for GROUP B type explosives which include Dynamite, Nitroglycerine, RDX, PETN, SEMTEX, Nitrocellulose and smokeless powder. If after spraying Expray-1 there is no color change, spray Expray-2. The almost immediate appearance of a pink color change indicates the presence of GROUP B explosives. Most plastic types of explosives belong to this group, including C-4 and Semtex. "I": Expray-3 for Nitrates Expray-3 is used to search for nitrate-based explosives which includes ANFO (ammonium nitrate-fuel oil), commercial and improvised explosives based on inorganic nitrates, black powder, flash powder, gun powder, potassium chlorate and nitrate, sulfur (powder), and ammonium nitrate (both fertilizer and aluminum). If there is still no reaction after using the Expray cans 1 and 2, but presence of explosives is still suspected, spray the same paper with Expray-3. A pink reaction indicates the presence of nitrates, which could be part of an improvised explosive...
