Right-angle grinder - the grinding face of the wheel or disc is at an angle of between 5 and 15 degrees from the grinding surface. Vertical grinder - the grinding wheel face is in contact with the surface. Use racks or hooks to store portable grinders. Stand away from the wheel when starting grinders. Warn co-workers to do the same.
Clean the grinder and area after completing the work. What should you avoid when using bench and pedestal grinders? Do not wear loose clothing or have long, loose hair (it may get caught in the spinning wheel). Do not plug the grinder in before making sure it and the wheel are stable and secured properly. Do not use a wheel that has been dropped.
Fasten the pedestal and bench grinders on a solid surface securely. Ensure all the guards are in place and secure before using a grinder. Adjust tool rests to within 3 mm (1/8 in.) of wheels. Never adjust rests while the wheels are moving. Work rest height should be on a horizontal centre line of the machine spindle.
A surface grinder is a tool that uses a stationary, abrasive, rotating wheel to shave or finish a metallic surface. Surface grinders can be dangerous if not used properly. Read the owner's manual carefully. Ensure that all parts, switches and plugs are in good working condition. Always check the grinding wheel for damage or wear before each use.
10 mai 2024 · A job safety analysis (JSA) is a process which helps assess a job to identify hazards and necessary control measures. In a job safety analysis, each basic step of the job is broken down into steps to identify potential hazards and to recommend the safest way to do the job. Other terms used to describe this procedure are job hazard analysis (JHA ...

Non-sparking tools also generate sparks, sometimes referred to as “cold sparks”. These cold sparks have a low heat level and do not ignite carbon disulfide, which has the lowest ignition point of any known substance. Therefore, while “non-sparking” tools may lower the risk of a spark, they do not eliminate the possibility of sparks.
Figure 1: Hierarchy of Control. Some sources may use a variation of this hierarchy of controls. For example, the CSA Standard 1002-12 (R2022): Occupational health and safety – Hazard identification and elimination and risk assessment and control includes a layer called "systems that increase awareness of potential hazards".
Weight of the tool. Ideally, a worker should be able to operate a tool with one hand. The weight of the tool may depend on the use: 2.3 kg (5 lb) if the hand tool will be used away from the body or above shoulder height. 1.4 kg (3 lb) or less for tools operated with one hand. 0.4kg (1 lb) for precision tools to allow for good control.
10 mai 2024 · Back to top. A hood - correctly called a local exhaust hood - is the point where contaminated air is drawn into the ventilation system. The sizes and shapes of hoods are designed for specific tasks or situations. The air speed (velocity) at the hood opening and inside the hood must be enough to catch or capture and carry the air contaminants.
