Seismic Explosives Need To Be Handled With Caution

By Vicki Diaz


There are many people risking their lives for seismic explorations. These men and women are part of an expedition, searching the earth's crust for traces of minerals, natural gases, crude oil or any other economically viable resource. Part of this exploration involves the use of seismic explosives for breaking down any natural barriers which are preventing the expedition.

The people working in this industry are responsible for handling extremely dangerous explosives. These devices have, and still do, cause hundreds of fatalities. If you are one of these people involved in this type of exploration, and are in charge of handling this dangerous task, then it is highly recommended that you read this article.

When entering the blasting area, turn off devices containing radio frequency. This means that in case you are carrying cell phones or radio, it is absolutely mandatory to switch the off and leave them behind. Electric detonators get triggered when the bridge wire in the detonator is heated by electric current. Radio frequency will trigger electric detonators causing it to explode untimely.

In the vicinity of an exploding device, there should be no equipment that carries a radio frequency. This may sound strange, but electronic items such as cellular phones and radios could cause the device to unexpectedly explode. This is due to the bridge wire, which is found inside of the detonator. If it becomes hot enough from electricity, it could cause an explosion.

Do not smoke, expose explosive to heat or open flame of any kind. When dealing with these chemicals it is very important to note that excessive heat can trigger the explosive. When heat crosses the critical amount, it will cause the explosive to detonate. This is why it is very important to not let explosives come in contact with any kind of open flame or heat.

Never expose it to an open flame. As discussed, any excessive amount of heat can detonate the explosive. When the heat within the bridge wire crosses the critical limit, it will detonate. Any unwarranted heat could set off the explosive, so it is imperative that you never take it near an open flame.

The cargo vehicle carrying the equipment needs to be in good shape. Any unwarranted pressure or force on the device is liable to set it off. Especially if the roads are not well maintained, it is imperative that the vehicle carrying the equipment bounces as little as possible. It is also necessary to cover all devices with a tarpaulin that is not only fire resistant, but waterproof as well.

Anyone carrying seismic explosives need to be extremely calm and cautious. It is very easy to set them off, and any false moves can have fatal consequences. If the safety rules are maintained, then the risk of detonation decreases. In the end, there will be fewer, if any, casualties.
