Using Abrasive Wheels: Rules for Optimal Performance and Safety
Grinders are essential tools in many industries, but they also pose significant safety risks if not used properly. From flying fragments to electrical hazards, workers must be aware of the potential dangers and follow safety guidelines.
This article will explore the key safety rules for using grinders and provide practical tips to ensure a safe working environment. By understanding and implementing these safety measures, you can protect yourself and your colleagues from accidents and injuries associated with grinder operations.
You’re probably using some abrasive wheel or wheels at your facility, either in your maintenance shop or on the factory floor. They’re versatile because these tools can be used to cut, grind, polish, and buff materials and surfaces, which can result in eye injuries, lacerations, and inhalation of particles. Following five safety rules for using this equipment is important since no matter what type of wheel is used, they all have one thing in common — they can be a source of injury.
Rule one — use the correct wheel
Make sure the wheel you select fits the speed specification you need. Ensure all parts are fitted correctly to prevent the wheel from falling apart during use.
Rule two — perform a “ring test”
Immediately before mounting, inspect all wheels and sounds (known as the ring test) to ensure they’ve not been damaged in transit, storage, or otherwise. Check the machine's spindle speed before mounting the wheel to ensure it does not exceed the maximum operating speed marked on the wheel.
Rule three — install a guard
The use of abrasive wheels can create flying particles. As the wheels spin at high RPMs, there is the danger that the wheel, or parts of the wheel, will fly off. Because of this, safety guards must be installed and located between the operator and the wheel during use. The guard must be adjusted so that pieces of an accidentally broken wheel will be deflected away from the operator. The top half of the wheel should be enclosed at all times.
Rule four — use the necessary personal protective equipment
Perform a hazard assessment to determine what personal protective equipment (PPE) you need to supply and require employees to use. This could include eye and face, hand, and hearing protection. Employees need training on how to don and doff, use, and maintain this PPE.
Rule five — train employees
On top of the PPE training, ensure employees running the wheels know how to operate it safely. Use the operations and maintenance manual as a basis for the training.
Key to remember
As versatile as abrasive wheels are, they can be a source of injury. Following these safety rules will help prevent your employees from getting injured.
