Powered Hand Tools - Pneumatic Tools - Basic Safety

What are pneumatic tools?

Pneumatic tools are powered by compressed air. Common types of air-powered hand tools used in industry include: These tools are versatile and efficient, but they require proper handling and maintenance to ensure safe operation.

How do you use pneumatic tools safely?

• context Review and understand the manufacturer's instructions before using a tool.
• context Wear safety glasses or goggles, or a face shield (with safety glasses or goggles), and, where necessary, protective footwear and hearing protection.
• context Use low-vibration tools, or tools with an auto-balance system or anti-vibration handle. Vibration can cause changes in tendons, muscles, bones and joints, and can affect the nervous system, including the development of Raynaud's Phenomenon.
• context Post warning signs where pneumatic tools are used.
• context Set up screens or shields in areas where nearby workers may be exposed to flying fragments, chips, dust, and excessive noise.
• context Ensure that the compressed air supplied to the tool is clean and dry. Dust, moisture, and corrosive fumes can damage a tool.
• context Use an in-line regulator filter and lubricator to increase tool life.
• context Keep tools clean and lubricated.
• context Maintain tools according to the manufacturer's instructions.
• context Use only the attachments that the manufacturer recommends for the tools you are using.
• context Install a safety cable or a whip check to prevent uncontrolled hose movement if a connection or coupling fails.
• context Prevent hands, feet, or body from being in the path of the tool in case the machine slips or the tool breaks.
• context Support heavy tools with counter-balances or tool balancers wherever possible to reduce physical fatigue.
• context Keep your hands and fingers warm̛ when using vibrating tools. Wear cold-resistant gloves or install an insulating sleeve on the tool handle if it is made of metal.

How should you handle air hoses?

• context Use the proper hose and fittings of the correct diameter and rating for the tool.
• context Use hoses designed to resist abrasion, cutting, crushing, and failure from continuous flexing.
• context Choose air-supply hoses that have a minimum working pressure rating of 1035 kPa (150 psig) or 150% of the maximum pressure produced in the system, whichever is higher.
• context Check hoses regularly for cuts, bulges, abrasions, or other damage. Tag and replace defective hoses immediately.
• context Blow out the air line before connecting a tool. Hold the hose firmly and direct airflow away from yourself and others.
• context Make sure that hose connections fit properly and are equipped with a mechanical means of securing the connection (e.g., chain, wire, or positive locking device).
• context Install pressure-release quick disconnects instead of disengagement-type connectors. Attach the male end of the connector to the tool, NOT the hose.
• context Do not operate the tool at a pressure above the manufacturer's rating.
• context Turn off the air pressure when the hose is not in use or when changing tools.
• context Avoid creating trip hazards by laying hoses across walkways or leaving them curled underfoot.
