• Safety glasses or a face shield: These will protect your eyes from any flying particles, objects or sparks that could hit them. You should always use a face shield and safety glasses when using an angle grinder . This is because the grinding disc can shatter or break, sending fragments flying in different directions. Also, some materials can produce sparks or flames when ground, which could ignite your hair or clothing. Therefore, it is essential to cover your eyes and face with suitable protection.
• Ear muffs or ear plugs: These will reduce the noise level and prevent hearing damage. Angle grinders can produce loud sounds that exceed 85 decibels (dB), which is the limit for safe exposure. Prolonged exposure to such noise can cause temporary or permanent hearing loss, tinnitus, or stress. Therefore, it is advisable to wear ear muffs or ear plugs that can reduce the noise by at least 20 dB.
• Gloves: These will protect your hands from cuts, abrasions, and heat. You should choose gloves that fit well and provide good hand movement. Leather gloves are recommended for most grinding applications . This is because leather is durable and resistant to heat and sparks. It can also prevent injuries from sharp edges on the workpiece or the grinding disc. You should also inspect your gloves regularly for wear and tear and replace them if necessary.
• Flame retardant or resistant clothing: These will protect your body from burns caused by sparks or heat. You should avoid wearing loose-fitting clothing that could get caught in the grinding disc. Natural fibre clothing and an apron are also advisable . An apron can also provide an extra layer of protection for your chest and abdomen. You should also tuck in your shirt and tie back your hair if it is long.
• Safety boots with steel toecaps: These will protect your feet from lacerations, impact, and compression. You should also avoid wearing sandals or open-toed shoes . This is because your feet are exposed to falling objects, such as the workpiece or the grinding disc, which could cause serious injuries. Steel toecaps can prevent crushing injuries from heavy objects or accidental kicks. Safety boots can also provide traction and stability on slippery or uneven surfaces.

b) Consider using Workpiece clamping devices for Maximum Safety

Workpiece clamping devices are essential tools in various industries, particularly in metalworking, woodworking, and construction. They serve the critical function of securely holding workpieces in place during machining, cutting, or fabrication processes. While they may not be personal protective equipment (PPE) In a traditional sense, they play a significant role in workplace safety.

Types of Workpiece Clamping Devices:

Workpiece clamping devices come in a variety of forms, including:

• Vices: Bench vices, machine vices, and drill press vices are commonly used in metalworking to securely hold materials.
