Consider disc size, arbor size, motor power, power source and rpm in choosing the correct grinder for the job. The RPM rating of the disc/blade must be higher than that of the angle grinder. Allow grinder to come to full speed and warm up before use and to a complete stop after use.
Safe Work Equipment – The safe system of work should only permit the use of the safest work equipment possible. A signature from the supervisor of the work, to confirm understanding of the work to be done, hazards involved and precautions required, and that the permit information has been explained to all permit users. A signature from the manager to confirm that the permit has been cancelled, all work under the permit has been completed and the area is safe.
This might be work that makes you hot, but it’s not the definition of hot work. A hot works permit should be used as a further control measure, especially in workplaces not designed for hot works. When hot work is carried out during a construction project or as part of maintenance work.
As per our company procedures all hot works must have an additional person to act as a Fire Watch, who must then remain in the area 1 hour after the works to watch for any signs of a fire etc. If you cut up a section of metal pole using an angle grinder with a cutting blade, classed as hot works, you or someone then needs to stay in the area for an hour before fitting the section you just cut. If you provide a fire watching person who actually watched the hot work, and that person does not observe any potential for fire caused by the hot work then a scan of the area immediately following the hot work should suffice, and the hot work should end at least one hour before the end of the shift, a final check is advisable before leaving the workplace at the end of shift.
Most hot work fires are caused because safe working procedures are not followed, hot work is done in an area not designed for this purpose, or because the risk assessment failed to pick up on combustible materials being present. A hot work permit is needed for the duration of the project where hot work is being undertaken. Having a hot work permit alone, will not eliminate the hazards that hot work introduces if it is not implemented and the advice in the permit not followed.
If you are ready to learn more about cutting metal and how to prevent sparks from starting a fire, then please read onward. Cutting metal with an angle grinder causes a lot of sparks. In summation, the sparks that result from cutting or grinding metal can be dangerous.
Prior to carrying out any hot work on site it is essential to implement a hot work permit system, which includes a detailed review, to identify all potential hazards associated with the proposed hot work activity and to eliminate the hazards or, where this is not reasonably practicable, control the resulting risks. The hot work permit should also address housekeeping and other measures such as inspection of work site and identification and handling of hot products subsequent to the hot work activity. The Australian Standard AS 1674.1 Safety in Welding and Allied Processes Part 1: Fire Precautions provides guidelines with regards to hot work activities and an example of a typical hot work permit.
Angle grinders are used for metalwork and fabrication such as grinding down welds. Make sure the disc speed limit is greater than the angle grinder operating speed. Never bump the grinder onto the work, or let the disc hit any other object while grinding. Keep the grinding disc at a 15 to 30-degree angle to the work. Never put a grinder down until the disc stops rotating. Never use a cut-off wheel for grinding or a grinding disc for cutting. Please return the Angle Grinder Toolbox Talk sign-in sheet to Environment, Health and Safety for recordkeeping.
is an angle grinder hot works Related Question:
Is using a grinder considered hot work?
Activities such as drilling, soldering, brazing, tapping, grinding, heat treating, chipping, thawing pipes, and abrasive blasting—often referred to as sand blasting—are all considered hot work.
What are examples of hot work?
Hot work is defined as any activity that involves open flames or produces heat and/or sparks capable of initiating fires or explosions. Examples of hot work include: welding, cutting, grinding, drilling, soldering, brazing, torch-applied roofing, etc.
What is hot work procedure?
Hot Work: Any temporary or permanent operation involving open flames or producing heat and/or sparks including but not limited to brazing, cutting, grinding, soldering, torch-applied roofing, pipe thawing and welding.
What is a designated hot work area?
A designated hot work area is a specific area designed or approved for such work, such as a maintenance shop or a detached outside location that is of noncombustible or fire-resistive construction, essentially free of combustible and flammable contents, and suitably segregated from adjacent areas. 2.3.
How many types of hot work are there?
Common hot work processes involve welding, soldering, cutting, brazing burning and the use of powder-actuated tools or similar fire producing operations outside of designated hot work areas. When flammable materials are not present, industrial processes such as grinding and drilling become cold work processes.
What is hot work equipment?
Expanding on OSHA’s definition, hot work means welding, brazing, cutting, soldering, thawing pipes, using heat guns, torch applied roofing and chipping operations, or the use of spark-producing power tools, such as drilling or grinding.
What is hot work and cold work?
The American Petroleum Institute defines hot work as any work that involves welding, burning, or hot tapping or the use of equipment near an open flame or equipment capable of generating a spark. Cold work describes a situation where the task being performed does not generate any sources of ignition.
Do I need a hot works permit?
Hot-work permits are required for any operation involving open flames or producing heat and/or sparks and must be prepared by a competent person. Hot works include brazing, torch cutting, grinding, soldering and welding.
What is the OSHA standard for hot work?
OSHA defines hot work to include riveting, welding, flame cutting, or similar fire- or spark- producing operations. Requirements for hot work are in 29 CFR 1917.152.
What is hot work precautions?
Fire protection. When hot work must be performed in a location that is not free of fire hazards, all necessary precautions shall be taken to confine heat, sparks, and slag so that they cannot contact flammable or combustible material.
When can I get a hot work permit?
When an employee wants to conduct any hot work job, the person should obtain the hot work permit from the project manager or from the relevant department. If two or more subcontractors are performing hot work on a single project, every one of them should obtain an individual hot work permit.
How long is a hot work permit valid for OSHA?
The duration of a hot work permit is limited to 30 days. These are guidelines. If there are conditions unique to the project or activities a contractor will be performing, exceptions can be made.
How long does the fire watch need to stay on the job after burning welding is completed?
1, Safety in Welding, Cutting, and Allied Processes, 2012 Fires can start after the hot work is complete. The fire watch must remain on site for a minimum of 60 minutes to monitor for smoldering fires, per NFPA 51B.
What PPE is required for hot work?
Appropriate PPE must be used whenever hot work is conducted. At a minimum eye, face, and hand protection is required. Attendants on hot work area monitoring must also be provided with appropriate PPE. Other PPE (i.e., boots, gloves, hard hat, fall protection, and protective garments) must be used as required by OSHA.
Where is hot working used?
The application of hot metal working includes hot rolling, forging, extrusion and hot drawing. The carbon steel and stainless steel products are rolled to form thin plates and extruded to produce desired shapes. Hot working is used for altering the form of iron and steel without fracture and use of excessive force.
