Are you feeling explosive? Good! Don’t get too carried away though, you shouldn’t have to be reminded that explosives are dangerous tools to play with. As important as demolishing is, it’s a very risky business. Explosive blasting is as important for applications such as tunnel building and excavations; while seeing things go boom is fun, safety comes first.
Whether you’re in mining, engineering or demolition, you need to always be aware of the safety precautions you need to adhere to when blasting rocks and other solid masses.
What is explosive blasting?
When working on an excavation or digging a tunnel, rocks and other large masses can only be removed by fighting them with fire. Explosive blasting, otherwise known as drilling and blasting, is used to clear away masses that are too heavy or too solid to be moved aside using heavy-lifting tools.
This technique is also used as a stronger alternative to rock and concrete splitters. It involves the drilling of holes in a mass big enough to insert explosives that will do away with the mass. This procedure is dangerous and so workers need to take the utmost precaution.
Safety tips for explosive blasting
Transport the blasting equipment carefully
Explosive blasting equipment needs to be transported with the utmost care. One wrong mistake could see the transportation vehicle going up in a cloud of smoke. When transporting blasting equipment to a demolition site, the vehicle must be given right of way at every junction to avoid accidents.
The vehicles themselves must be in good working condition and must be covered on all sides with signs or placards that display the word “Explosives”. A red flag that’s visible from all angles needs to be hoisted as well. Fire extinguishers should also feature in this explosive carriage.
When blasting rocks and concrete, two major safety concerns exist: premature detonation and flyrock. The former occurs when the explosives are detonated before all workers are clear of the explosion range.
Premature detonations can occur during the loading or tying-in procedures or while awaiting the scheduled firing. Since explosives need heat or shock energy to detonate, contact with these energy sources before the scheduled detonation time can prove to be costly. When planning your blasting process, it’s crucial to strategize everything to the dot to avoid human error.
To take the utmost precaution for your explosive blasting, consider the following:
- Use cones or beams to demarcate the blast site.
- Only trained and necessary personnel should be allowed onto the blast site.
- Complete the drilling of holes prior to loading the explosives or keep the drilling at a distance where it cannot intersect a loaded hole.
Be wary of flyrock
It would take another blog post to explain what flyrock is, how it’s caused and what measures exist to avoid this hazard. Using blasting best practices can save lives and thwart any potential or serious damage to your property.
