Pneumatic Tool Safety
Pneumatic tools, which are powered by compressed air, are widely used in industrial and construction settings. Common pneumatic hand tools include pick hammers, drilling hammers, scraper, jackhammers, chipping hammers, breaking hammers, rammers, air-shovelsanders, riveting hammers and wrenches. Although pneumatic tools take some special handling, they actually save a great deal of time and effort and are relatively easy to use.
As the following instructions cannot cover all possibly occuring cases, sound common sense must be employed when working with pneumatic tool and in the vicinity of this machine
There are several potential dangers associated with the use of pneumatic tools. The main hazard is being struck by one of the tool’s attachments.
Basic Pneumatic Tool Safety
• The priority of labour safety always prevails over any other operation demands
• Use the right tool for the job.
• Every person to work with or service Pneumatic Tools must provably read or be familiarized with the manufacturer’s instructions so as to understand them.
• Do not operate the tool at a pressure above the manufacturer’s rating.
• Stay on a safe and stable platform while operating
• Do not touch the trigger until you are ready to operate.
• Always wear safety shoes, goggles, ear defenders, gloves and other safety equipment prescribed for the given task. Do not stay in a noisy environment without effective ear defenders.
• Rock chips and debris can be projected in at high velocities as Pneumatic Tools operates. Wear safety goggles.
• Frequent use of hand-held vibrating tools may trigger onset of the Hand-Arm Vibration Syndrome (HAVS). Take short breaks from work and always keep your hands warm. Immediately report any issues like numbness in fingers to your superior.
• Ensure that the compressed air supplied to the tool is clean and dry. Dust, moisture, and corrosive fumes can damage a tool. An in-line filter, regulator, and lubricator may increase the life of the tool.
• Keep tools clean, lubricated, and maintained according to the manufacturer’s instructions.
• Disconnect tools when not in use, before servicing, when clearing a jammed fastener, and when changing accessories such as bits and cutters.
• Use only the attachments that the manufacturer recommends for the tools you are using.
• Attachments, such as chisels on a chipping hammer should be secured with a safety clip or retainer to prevent them from being
unintentionally ejected during tool operation.
• Make sure that the tool is fastened securely to the hose. A short wire or positive locking device attaching the air hose to the tool serves as an added safeguard.
• Assure that Pneumatic Tools will not harm anyone by falling and always keep in mind its weight to prevent injury.
Air Hoses
• If an air hose is more than 1/2 inch in diameter, a safety excess flow valve should be installed at the source of the air supply to shut off the air automatically in case of hose failure.
• Choose air hoses that have 150 % of the maximum pressure produced in the system.
• Use hoses specifically designed to resist abrasion, cutting, crushing, and flexing.
• Keep hoses away from heat, oil, sharp edges, and potential physical damage.
• Check hoses regularly for cuts, bulges, and abrasions. Tag and replace, if defective.
• Blow out the air line before connecting a tool. Hold the hose firmly and blow away from yourself and others. This will help ensure there is no debris or water inside the hose.
• Do not release any joints that are under pressure. Always switch off the air supply and bleed hoses first.
• Turn off the air pressure to hose when not in use.
• Do not carry a pneumatic tool by its hose.
• Avoid creating trip hazards caused by hoses laid across walkways or curled underfoot.
Unsafe Use of Compressed Air
• Compressed air is dangerous! Do not aim an air hose at yourself or other people. Do not use pressurized air to clean the site or your clothing. Use vacuums, dusters, or brooms instead.
