An angle grinder is a hand held power tool used for multiple tasks such as grinding, cutting, polishing, and sanding. These power tools that are referred to as side grinders or disc grinders as well, offer tremendous flexibility and control by allowing the user to work at an angle on the surfaces. They can be corded, cordless, or pneumatic, depending on the power source.
Angle grinders bring unique challenges that make it essential to take certain precautions. A list of unique challenges that make safety precautions necessary are listed below:
1.Noise
Angle grinders generate noise while being operated and prolonged exposure to noise could damage the hearing capacity of the user. In extreme cases, there may even be permanent loss of hearing making it essential to take necessary safety precautions.
Use of earmuffs or earplugs reduces the intensity of the noise thereby reducing discomfort for the user and protecting their hearing capacity.
2.Vibrations
When angle grinders are used over an extended period of time, the user is subjected to vibrations from the power tool. Since it is hand held, prolonged use may cause numbness or tingling sensation in the arms due to exposure to vibrations or even pain.
In order to prevent Hand-Arm Vibration Syndrome (HAVS), it is advisable to wear protective gloves. These ensure comfort and also protect the user from onset of any symptoms due to vibrations. Taking regular breaks while working is also essential.
3.Dust inhalation
The use of angle grinders tends to produce dust particles due to the grinding process. Prolonged inhalation of dust can lead to respiratory conditions such as asthma or lung disease.
To prevent any health issues due to dust inhalation it is advisable to wear a mask while working. Dust extraction systems in the workplace also help to keep dust levels low and the workplace healthy.
4.Fire hazard
Use of angle grinders tends to generate sparks. If there are any inflammable materials in the vicinity when the angle grinder is being used, they may ignite. Keeping inflammable materials away from the workplace and the workplace clean and organized at all times helps prevent any fire incidents.
Keeping fire extinguishers handy while working is another precaution well worth taking.
5.Cuts and bruises
Any contact with the angle grinder while it is in use will lead to cuts and abrasions. If it is working at higher speeds it may cause deep cuts. Wearing gloves at all times while handling the angle grinder prevents any cuts and abrasions.
Fragments of debris may also fly around while using angle grinders. Wearing face masks and work goggles prevent any injuries due to this.
6.Electric shock
While using corded angle grinders, there is a possibility of electric shock if the cord is damaged. To prevent this it is absolutely essential that the electric cord is inspected at regular intervals. As part of the regular maintenance procedure, the cord also needs to be replaced from time to time.
Wearing gloves at work is also a precautionary measure.
7.Breakage of grinder disc
If the grinder disc is damaged or breaks during use, it may cause injury to the user. To prevent the disc from breaking, the disc has to be inspected before use and replaced as required. Wearing gloves at work, wearing glasses or a face protection mask, all help to prevent injuries due to any disc breakage.
8.Entanglement in cords
Another challenge when using a corded angle grinder is that it may get entangled in loose clothes causing damage. It is important to wear fitted clothing and appropriate work gear to prevent any such mishaps.
9.Kickback
If the angle grinder catches on metal while working there is an unexpected kick back. This could lead to a loss of grip for the user and may cause injuries.
Maintaining a firm grip on the power tool and positioning the body to the side of the wheel are both important to prevent kickback. Positioning is important as it helps minimize the risk of injury.
Angle grinders are highly versatile power tools suitable for both professional and DIY projects. This makes them an integral part of workshops, construction sites, and homes. Understanding the challenges of using the angle grinder and taking the necessary precautions will ensure the prevention of any injury and make for a satisfying work experience.
