Japanese Knotweed Eradication

Japanese knotweed is once again in full swing and terrorizing the UK's gardens and countryside, if you're dealing with it yourself you want to have got the first treatment on the knotweed in already. The best plan for tackling it yourself is to use a glyphosate based weed killer (a domestic use herbicide assuming you don't have a license for professional herbicides) and apply it soon after the knotweed has started growing while it's between 0.5 and 1m tall.

Get the herbicide as much as you can on the green matter of the plant rather than the soil for maximum effect and be very careful about any waste which comes from the knotweed lest you cause the plant to spread, which could result in you being prosecuted since it's illegal to cause knotweed to grow in the UK. When disposing of waste it's important to remember waste could be on tools or shoes. Any waste you do have should either be left where it is or disposed of as controlled waste. Under no circumstances should it be composted, thrown away with normal waste or, god forbid, fly tipped.

After the first treatment, treating again later on in the season can help to speed up killing knotweed and even up to a third time. You should expect to have to repeat this process for several years however; knotweed is a tenacious plant and to get rid of it, you need to match its patience. If you're unsure when dealing with knotweed yourself at any point, don't hesitate to contact a professional and get advice on how to deal with your case of knotweed.

Also, if you see Japanese knotweed on the side of the road or near your home, you should contact your environment agency and let them know so they can make sure it gets dealt with; the longer it's left and not known about, the more it will spread and the harder the job of getting rid of it will be.

The Dangers of Electricity in Industry

When we consider electrical safety around the house there are common things that come to mind. Things such as not using damaged cables or plug sockets, not having exposed wires and avoiding water with electrical devices not designed to get wet, such as toothbrushes. In the home though, the highest voltage you are likely to see in the UK is going to be around 240 volts.

While this can certainly still be deadly, in higher voltage applications the chances of something far more dangerous happening start; arc flashes. While still possible at lower household voltages, high voltage applications; over 600V, have a significantly higher risk of arc flash, and with that comes a new multitude of dangers to be accounted for.

The most obvious one is the heat; where the electric current forces its way through the air, the massive amperage causes everything to superheat to incredible temperatures up to 20,000 Celsius; a temperature hotter than the surface of the sun! At these temperatures substances don’t exist which can withstand this temperature.

This temperature is fairly concentrated at the point where the arc flash occurs, the temperature will quickly drop with distance from the epicentre, despite this though, superheated matter including molten metal will be spewed out. This is more than capable of igniting clothing and other nearby material and it is for this reason that one of the biggest killers from arc flash incidents is burning on victims; where clothing ignites, victims can receive burning on a huge percentage of their body, the chance of infection then becoming extremely high. Here one of the most important things is to have FR clothing to stop this from happening.

Another big issue of arc flash incidents is the sheer amount of energy released, where tens of thousands of amps can be released at hundreds of volts, an arc flash lasting just a fraction of a second can release phenomenal amounts of energy comparable to explosives. Of course most explosives work on a principle of creating gasses from solids; since gasses take up a much larger volume than solids you get a very rapid expansion, which is also increased by the exothermic release of explosives. Comparatively, an arc flash releases almost all of its energy in heat and light, so the shockwave from an arc flash won’t have the same mechanical force as an actual explosive, it is significant enough to be dangerous however, many people are thrown across rooms and suffer irreparable damage to their hearing as well as eyesight from the extremely bright light emitted.

Stopping arc flashes is a tricky processes and one of the best tools against the dangers of arc flash is to know where they will happen, making arc flash assessments a hugely important part of industry. Another good way around arc flashes is to do work using hot sticks and hydraulic systems. Electrical PPE should be considered your last line of defence, so be careful out there.

Drilling for water

many people in the world live lives without clean water. An effective way of curing this is to drill a well sufficiently deep that it can avoid contamination. Here are some of the ways in which that it achieved.
