METALWORK: CUTTING OUT THE DANGERS (GUEST POST)

The market for welding equipment and profile cutters has broadened considerably in recent years as such machinery become more affordable, less cumbersome and thus available to the majority of the population. The hazardous methods used to accurately carve shapes from metal sheets are now adopted equally by unskilled hobbyists working in their own home and heavy industries of mass production. The widespread availability and unregulated use of profile cutting machinery has exposed more people to harm. Looking at plasma cutting in particular, it is easy to see the dangers of this trade and the necessity of certain safety precautions which all users must adhere to. 

The Risks 

From arc-eye to smouldering debris on the skin, the dangers associated with plasma cutting are all extremely hazardous to anybody working in the vicinity. One serious risk is the fire hazard created by the arc of plasma which not only emits intense heat but also gives off sparks, which can land on nearby surfaces, clothing or skin. The arc also produces a bright glare which is damaging to the eyes. Molten metal and shards of freshly cut debris can be airborne and can burn or cut exposed skin. Then there are the fumes released by the metal during the process which can create an immediate choking hazard or more long term health problems. Any coating on the metal (ie. galvanised steel) must be removed beforehand as they produce truly toxic fumes. Finally, the extreme power output of a plasma cutter creates a high risk of electrocution. It certainly sounds like a risky business, but with the following precautions in place, profile cutting can be a safe and efficient way to manufacture cut metal. 

The Solutions 

Before starting any form of profile cutting, it is essential to inform any people in the vicinity that the equipment is being used so that each individual can take the necessary action to avoid harm. In industrial manufacturing, no unauthorised persons should be allowed to use a plasma cutter and it is essential that every operator undergoes appropriate training. Protective clothing and eye-wear is an absolute must for all machine operators. Goggles must provide unrestricted vision and movement while protecting the eyes from glare and debris. This means a suitably shaded, thick and unbreakable lens. Clothing must be full length to cover every inch of skin, fire resistant and without cuffs which could catch smouldering debris. It is essential to ventilate the room with fresh air or wear breathing apparatus where the fumes are likely to be intense. The risk of electrocution can be eliminated by being well grounded by wearing rubber soled boots and gloves as well as the standard welding gloves. There also must be no moisture or water around which could conduct electricity throughout the room. Finally, ensure that the plasma cutting machinery is placed as far from surrounding objects as possible to avoid sparks leaping to any material that could act as a fuel for fire.

In the workplace, the employer must ensure that these regulations are upheld to the highest standards to guarantee staff safety. At home, the individual is responsible for their health and ultimately their life, so such hazardous metalwork should not be undertaken lightly.

THE DANGERS OF WIRING AND HOW TO STAY SAFE (GUEST POST)

Sent to us by Jake @ CustardMedia.co.uk

Working with electrical wiring can be very dangerous. This is particularly true for those who have never worked with wiring before. If you are planning to complete a do-it-yourself wiring job, you need to understand the dangers of working with wiring and how you can avoid these dangers. Safety should always be your primary concern. Even though it may be a bit less expensive to do your own repair jobs and home maintenance, it is always a much better idea to call in a professional if you are not completely certain of what you are doing. Electrical shock can be fatal and is one of the most common incidents that occur when homeowners work on their own wiring. Aside from electrical shock, you also risk a fire hazard if your wiring is not done properly. That being said, here are a few tips that will help you to ensure your safety when working with electricity. 

1.       Know when you are in over your head. Again, if you are not a professional electricity expert, you should know when to call one. If at any time you realize that you are completely unsure of what you are doing, stop and call in an electrician. It is much better to pay a few extra dollars and get the job done properly than to risk electrical shock or fire.

2.       Make sure that all power is turned off before you begin working on any electrical wiring. You should turn off the power at the main and check to see that it is indeed turned off. You can turn off each individual circuit as needed as long as you check to ensure that the proper circuit is turned off before you begin. If you are not certain as to which circuit runs the electricity you need to turn off, turn off the entire main just to be on the safe side.

3.       Wear gloves when possible to protect your hands. When working with electrical wiring, there may be sharp points or edges that can cause you to cut yourself. Protect yourself from injury by wearing work gloves whenever you can.

4.       Rubber boots can help to protect you when working with electricity as well. Remember that water and electricity do not mix well so if you are working with electricity and there is any chance that water or dampness may be evident, wearing rubber boots can help you to avoid electrical shock. Rubber boots will stop an electrical current from reaching your body. Make sure that you check your rubber boots to ensure that there are no holes that could allow water to touch your feet.

5.       Safety glasses are very important when working with electricity. These will help you to protect your eyes from dust and debris as well as electrical sparks. If you are working with electrical wiring and you need to cut holes or otherwise drill into a wall or ceiling, safety glasses will ensure that you do not get debris in your eyes that could cause infection or in very extreme cases, blindness.
