# Six Steps to Nail Gun Safety (cont.) ## Worksite Story A construction worker accidentally drove a 16 penny framing nail into his thigh. It didn't bleed much and he didn't seek medical care. He removed the nail himself. Three days later he felt a snap in his leg and severe pain. In the emergency room, doctors removed a sheared of nail and found that his thigh bone had fractured. Not all injuries are immediately visible. Failure to seek medical care can result in complications and more serious injuries. ## 6 Provide first aid and medical treatment Employers and workers should seek medical attention immediately after nail gun injuries, even for hand injuries that appear to be minimal. Studies suggest that 1 out of 4 nail gun hand injuries can involve some type of structural dam- age such as bone fracture. ¹³ Materials such as nail strip glue or plastic or even clothing can get embedded in the injury and lead to infection. Barbs on the nail can cause secondary injury if the nail is removed incorrectly. These complica- tions can be avoided by having workers seek immediate medical care. ## A Word about Other Hazards Air pressure. Pneumatic tools and compressor use are regulated under OSHA's Construction standard at 29 CFR 1926.302(b). The provisions in this standard that are relevant for nail guns are provided below. (1) Pneumatic power tools shall be secured to the hose or whip by some positive means to prevent the tool from becoming accidentally disconnected. Note: An OSHA letter of interpretation 14 allows the use of a quick disconnect with a pull-down sleeve to meet this requirement. It is composed of a male fitting (connector) and female fitting (coupling) that has a sleeve which must be pulled away from the end of the hose to separate the two fittings to prevent the tool from becoming accidentally disconnected. (3) All pneumatically driven nailers, staplers, and other similar equipment provided with automatic fastener feed, which operate at more than …

# PNEUMATIC (AIR) TOOLS Date Posted: 05/13/2025 ## Pneumatic (Air) Tools Choosing the right tool for the job is essential in construction. While specific needs vary, one of the best items to use is pneumatic (air) tools. While pneumatic tools are common throughout the industry, many teams still rely on electric or gas options. Pneumatic tools, powered by compressed air, can be a valuable and portable addition to electrical tools on construction sites, industrial workshops, and any work site where power tools are used. While Pneumatic tools offer several benefits, like any tool, there is potential for harm. There are several hazards associated with the use of pneumatic tools. First and foremost is the hazard of being struck by one of the tool's attachments or by some fastener you use with the tool. ## COMMON AIR TOOLS IN CONSTRUCTION All pneumatic tools on the work site must be maintained in good condition. If the pneumatic tool comes with a guard or other safety mechanism, it must be installed, used according to the manufacturer's specifications, and installed whenever the tool is used. Workers should never lift or hold a tool by its hose. Pneumatic tools must be inspected to ensure that the tools are fastened securely to the air hose to prevent them from becoming disconnected. A short wire or positive locking device, commonly known as a "whip check," attaching the air hose to the tool should be used to serve as an added safeguard. Commonly used air tools in Construction include, but are not limited to: ## Drills Grinders • Impact wrenches • Nailers - Riveters • Sanders • Saws • Screwdrivers • Staplers ## COMMON PNEUMATIC TOOL HAZARDS • Attachments or fasteners are not properly secured: To control this hazard, make sure your pneumatic impact tools have safety clips or retainers that prevent devices from being accidentally discharged. • The tool operator misses the intended surface, and a nail or staple strikes a bystander: To prevent this from hap…

# PNEUMATIC (AIR) TOOLS (cont.) ## GENERAL REQUIREMENTS FOR THE USE OF PNEUMATIC TOOLS • Read the manufacturer's use instructions and understand tool operation before use. • Tool users must be trained on safe operation. • Follow the manufacturer's specifications to match the attachment's air pressure ratings. • Wear appropriate personal protective equipment. • Safety glasses or goggles or face shield (with safety glasses or goggles) • Hearing protection • Closed toe and heel shoes. • Take damaged tools out of service and report them to your supervisor. • Keep tools clean, lubricated, and maintained according to the manufacturer's instructions. • Install quick disconnects, attaching the male end of the connector to the tool, NOT the hose. • Turn off the air pressure to the hose when not in use or when changing tools. • Use hoses designed to resist abrasion, cutting, crushing, and failure from continuous flexing. • All hoses exceeding 1/2-inch inside diameter must have a safety device at the source of supply or branch line to reduce pressure in case of hose failure. • Inspect hoses regularly for bulges, cuts, and cracks. • Minimize trip hazards from the hose by ensuring that the hose does not cross a walkway. • Set up screens or shields where nearby workers may be exposed to flying fragments, chips, or dust. • Avoid using compressed air to clean a machine, work area, or yourself. • Never discharge compressed air at another person or yourself. You must not use compressed air at the nozzle for cleaning purposes except where it is reduced to less than 30 PSI and only with effective chip guarding and personal protective equipment. ## REFERENCES WAC [redacted identifier] - Power Operated Hand Tools WAC [redacted identifier] - Compressed Air Tools 1926.302 - Power-operated hand tools. | Occupational Safety and Health Administration (osha.gov)

# Powered Hand Tools - Pneumatic Tools - Basic Safety (cont.) ## How do you use pneumatic tools safely? (cont.) Reduce physical fatigue by supporting heavy tools with a counter-balance wherever possible. Tool Balancer Flexible Air Delivery System (of Correct Size) Power Activator Padded Handle (or sleeve with comfortable diameter) ## How should you handle air hoses? - Use the proper hose and fittings of the correct diameter. - Use hoses specifically designed to resist abrasion, cutting, crushing and failure from continuous flexing. - 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. - Check hoses regularly for cuts, bulges and abrasions. Tag and replace, if defective. - Blow out the air line before connecting a tool. Hold hose firmly and blow away from yourself and others. - 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). - Install quick disconnects of a pressure-release type rather than a disengagement type. Attach the male end of the connector to the tool, NOT the hose. - Do not operate the tool at a pressure above the manufacturer's rating. - Turn off the air pressure to hose when not in use or when changing power tools. - Do not carry a pneumatic tool by its hose. Avoid creating trip hazards caused by hoses laid across walkways or curled underfoot. - Do not use compressed air to blow debris or to clean dirt from clothes.
