Allow the tool to come up to operating speed prior to grinding or cuttin g. The employee should never stand in the plane of rotation of the wheel as it accelerates to full operating speed. Portable grinding tools need to be equipped with safety guards to protect workers not only from the moving wheel surface, but also from flying fragments in case of wheel breakage.

When using a powered grinder:. Pneumatic tools are powered by compressed air and include chippers, drills, hammers, and sanders. There are several dangers associated with the use of pneumatic tools. Pneumatic tools must be checked to see that the tools are fastened securely to the air hose to prevent them from becoming disconnected.

A short wire or positive locking device attaching the air hose to the tool must also be used and will serve as an added safeguard. In general, the same precautions should be taken with an air hose that is recommended for electric cords, because the hose is subject to the same kind of damage or accidental striking, and because it also presents tripping hazards.

When using pneumatic tools, a safety clip or retainer must be installed to prevent attachments such as chisels on a chipping hammer from being ejected during tool operation. Pneumatic tools that shoot nails, rivets, staples, or similar fasteners and operate at pressures more than pounds per square inch 6, kPa , must be equipped with a special device to keep fasteners from being ejected, unless the muzzle is pressed against the work surface.

Airless spray guns that atomize paints and fluids at pressures of 1, pounds or more per square inch 6, kPa must be equipped with automatic or visible manual safety devices that will prevent pulling the trigger until the safety device is manually released. Eye protection is required, and head and face protection is recommended for employees working with pneumatic tools. Screens must also be set up to protect nearby workers from being struck by flying fragments around chippers, riveting guns, staplers, or air drills.

Compressed air guns should never be pointed toward anyone. A chip guard must be used when compressed air is used for cleaning. Use of heavy jackhammers can cause fatigue and strains. Heavy rubber grips reduce these effects by providing a secure handhold.

Workers operating a jackhammer must wear safety glasses and safety shoes that protect them against injury if the jackhammer slips or falls. A face shield also should be used.

Noise is another hazard associated with pneumatic tools. Working with noisy tools such as jackhammers requires proper, effective use of appropriate hearing protection. Fuel-powered tools are usually operated with gasoline. The most serious hazard associated with the use of fuel-powered tools comes from fuel vapors that can burn or explode and also give off dangerous exhaust fumes.

The worker must be careful to handle, transport, and store gas or fuel only in approved flammable liquid containers, according to proper procedures for flammable liquids.

Before refilling a fuel-powered tool tank, the user must shut down the engine and allow it to cool to prevent the accidental ignition of hazardous vapors. Fire extinguishers must also be available in the area. Powder-actuated tools operate like a loaded gun and must be treated with extreme caution.

In fact, they are so dangerous that they must be operated only by specially trained employees. When using powder-actuated tools, an employee must wear suitable ear, eye, and face protection.

The user must select a powder level — high or low velocity — that is appropriate for the powder-actuated tool and necessary to do the work without excessive force. The muzzle end of the tool must have a protective shield or guard centered perpendicular to and concentric with the barrel to confine any fragments or particles that are projected when the tool is fired.

A tool containing a high-velocity load must be designed not to fire unless it has this kind of safety device. To prevent the tool from firing accidentally, two separate motions are required for firing. The first motion is to bring the tool into the firing position, and the second motion is to pull the trigger. The tool must not be able to operate until it is pressed against the work surface with a force of at least 5 pounds 2.

If a powder-actuated tool misfires, the user must hold the tool in the operating position for at least 30 seconds before trying to fire it again. This procedure will make the faulty cartridge less likely to explode. The bad cartridge should then be put in water immediately after removal. If the tool develops a defect during use, it should be tagged and must be taken out of service immediately until it is properly repaired.

Safety precautions that must be followed when using powder-actuated tools include the following:. When using powder-actuated tools to apply fasteners, several additional procedures must be followed:. The fluid used in hydraulic power tools must be an approved fire-resistant fluid and must retain its operating characteristics at the most extreme temperatures to which it will be exposed.

The exception to fire-resistant fluid involves all hydraulic fluids used for the insulated sections of derrick trucks, aerial lifts, and hydraulic tools that are used on or around energized lines. This hydraulic fluid shall be of the insulating type. All jacks — including lever and ratchet jacks, screw jacks, and hydraulic jacks — must have a stop indicator, and the stop limit must not be exceeded.

A jack should never be used to support a lifted load. Once the load has been lifted, it must immediately be blocked up. Put a block under the base of the jack when the foundation is not firm, and place a block between the jack cap and load if the cap might slip. To set up a jack, make certain of the following:. Proper maintenance of jacks is essential for safety. All jacks must be lubricated regularly.

In addition, each jack must be inspected according to the following schedule: 1 for jacks used continuously or intermittently at one site — inspected at least once every 6 months, 2 for jacks sent out of the shop for special work — inspected when sent out and inspected when returned, and 3 for jacks subjected to abnormal loads or shock — inspected before use and immediately thereafter.

Working in a safe and healthful environment can stimulate innovation and creativity and result in increased performance and higher productivity. To assist employers and employees in developing effective safety and health management systems, OSHA published recommended Safety and Health Program Management Guidelines Federal Register 54 16 : , January 26, These voluntary guidelines can be applied to all places of employment covered by OSHA. The guidelines identify four general elements that are critical to the development of a successful safety and health management system.

These are the following:. More results Generic filters Hidden label. Hidden label. Fire Ball Extinguisher November 14th, HSE Case January 2nd, We love this simulator, have tried it once. Very realistic and lets the man experience the real shock of impact and demonstrates that we, humans are not as strong as we thought. Work in Confined Space is never easy! Hand Tools and Relevant Safety Precautions.

Five basic safety rules can help prevent hazards associated with the use of hand and power tools: Keep all tools in good condition with regular maintenance. Carry with care Never carry tools up a ladder. If you need to take tools up to a height use a bag or hoist them up in a bucket.

Don't pocket sharp objects Never carry sharp or pointed tools in your pocket. Instead, carry them in a toolbox. Be aware of your surroundings Always be aware of the people around you when using tools. Use the right tools Always use the right tools for the job. Never use a tool for a different purpose than it was intended. You risk damaging the tools and injuring yourself. Follow instructions Only operate tools according to manufacturers' instructions.
