Caution: 9 inch angle grinders have been banned on some work sites due to the increased risk of injury. Provide operators with training and instruction in safe work procedures for angle grinders. Provide one-on-one supervision for workers receiving training in the use of angle grinders or people who are unfamiliar with their use.
Because the risk of projectiles can only be minimised and not eliminated, as an angle grinder safety measure to stop injury, you must wear PPE to protect you from the risk of projectiles, especially eye and head protection. You might not be able to stop this, so you should make sure you are in a safe environment to use an angle grinder. In this post, we focused on angle grinder safety issues and different types of angle grinder accidents.
Angle grinder accidents are one of the most dangerous hazards for people that use these types of tools. The User should be able to identify them respectively to avoid angle grinder accidents. So that 7″ angle grinder wheel, rated at 7,000 rpm may not be used in a 4.5″ angle grinder which rating is 11,000 rpm.
A series of penetrating facial wounds associated with angle grinder use are presented and the management and prevention of these injuries discussed. We present a series of three penetrating facial wounds associated with angle grinder use. Table 2Safe use of angle grindersSafety measureAdvantageUse the correct disc size and replace the disc when wear is obvious or the disc is chippedReduces the risk of a foreign body injury as a result of disc disintegrationStop using if vibration is very apparentDo not remove the guard unless for maintenanceIncreases personal protection from direct and foreign body injuryNever use an angle grinder overheadStand perpendicular to the plane of the cutting wheel, i.e. cut in a para-coronal plane to reduce the risk of kick back towards the sagittal plane of the bodyAlways wear appropriate personal protective equipment/clothingThe cases presented illustrate that the high speed disc of angle grinders does not respect anatomical boundaries or structures.
Whether the accessory on that angle grinder is a grinding disc, a cutting disc, or a wire wheel, you have something that is spinning at speeds anywhere from 9,000 to 11,000 RPM, inches from your hands, fingers, body, and face. I can guarantee you, if you are running an angle grinder for your job without a guard, at some point you are going to be injured by that grinder. If your angle grinder goes in and out of a tool crib every day, and if that tool crib issues you a grinder with an accessory on it, make sure to let it run no load for a minute.
The majority of these injuries occur from an abrasive blade shattering, diamond-blade segment loss, or the angle grinder kicking back. An incredibly dangerous occurrence, the easiest way to prevent this from happening is simply not use these silicon-carbide blades, often referred to as throwaway blades. The best way to minimize these accidents is to use a blade with a strong weld, or no weld at all.
In this article, I want to talk about the possible dangers of using an angle grinder, as well as some safety tips that you should keep in mind that will help you avoid accidents while using the tool. The biggest safety risk of an angle grinder when compared to die grinder comes from the shattered abrasive disc. The angle grinder safety guards can greatly reduce the accidents that occur from shattered abrasive discs.
why are angle grinders dangerous Related Question:
What are most angle grinder injuries from?
In 2008, nearly 25,000 were injured nationwide while using angle grinders (U.S. Consumer Product Safety Commission). The majority of these injuries occur from an abrasive blade shattering, diamond-blade segment loss, or the angle grinder kicking back.
Why do angle grinders explode?
Grinding operations generate tremendous amounts of heat. This heat causes expansion and if foreign materials are embedded in the stone then the differential rate of thermal expansion between the two materials can cause a wheel to shatter.
Why is a grinder so dangerous?
Injuries resulting from the use of angle grinders are numerous. The most common sites injured are the head and face. The high speed disc of angle grinders does not respect anatomical boundaries or structures and thus the injuries produced can be disfiguring, permanently disabling or even fatal.
How common are angle grinder accidents?
Abstract. Angle grinders are amongst the most dangerous tools used in industry and agriculture. Over 5000 documented injuries are related to their use each year which are commonly triggered by a shattering of the abrasive wheel. These injuries are often accompanied by suboptimal health and safety standards.
Do angle grinder sparks hurt?
Conclusion. In summation, the sparks that result from cutting or grinding metal can be dangerous. Not only can they burn the eyes and skin, but they also can also ignite flammable materials such as wood, paper, or fabric causing a fire.
Is an angle grinder safe?
They most often spin anywhere from 9000RPM to 11000 RPM, just inches away from your body, face, and hands. So, when you are using an angle grinder wire wheel, grinding disc, or cutting disc, any of them can easily cause severe damage to you or those around you if handled improperly.
Can grinders cause fires?
Cutting metal with an angle grinder causes a lot of sparks, however, the sparks that result are not that serious of a fire hazard. The reason being that the sparks emitted (generally) do not get hot enough to ignite, therefore, the chances of an accidental fire occurring are quite low.
Are grinder sparks dangerous?
Those from grinding, as Richard said have a very small mass and want hurt your skin. The sparks from cutting metal are highly dangerous. They consist of molten, possibly burning metal and look violent and dangerous, so you will not willingly get near.
Why do sparks not hurt?
The thermal energy an object has depends on its temperature, its mass and the type of material it is made from. Since these sparks have such low mass, they don’t have very much thermal energy. Without much energy, they don’t have the capacity to do very much damage to your skin.
Do sparks burn you?
Fireworks are burning metals which produces light. Sparks from a welder are slightly different. They are small bits of metals blasted out from the point of contact between the two metals (in electrowelding). However, they are not meant to burn and produce light.
Can sparks cause burns?
The flying sparks and hot metal, slag, spatter, hot workpiece, and hot equipment can cause burns. Additionally, arc rays can cause radiation burns .
Should you wear gloves with angle grinder?
“Gloves should be well-fitted and provide good dexterity and the best possible protection against cut or abrasion and heat,” he said, adding that vibration resistant properties are also of benefit, specially on angle grinders that don’t have Milwaukee’s built in anti-vibration features.
What can you not do with an angle grinder?
Angle Grinder Use Angle grinders generate sparks. When required obtain a hot work permit before use. Keep work area clear of debris and flammable materials. Do NOT use in areas where there is grain dust or other combustible dust accumulation.
