ANSI A10.3-2006 classifies powder-actuat-ed tools according to velocity. With increas-ing velocity, rules for usage become more stringent, for example with regard to equip-ping the tools with shields. The lowest velocity tool capable of performing the application should be used. Class of Average Maximum single powder-actuated test velocity test.
Do you know what it takes to stay safe when using PATs?
For most contractors today, powder-actuated tools (PATs) are a way of life. By eliminating the need to drill holes with a concrete drill bit or use anchors and screws for fastening applications, PATs have become a necessity in the electrical construction industry—enabling users to attach conduit clips, electrical junction boxes and various other items to concrete, masonry, and steel surfaces. Although the benefits are obvious, there are several safety concerns you must address before becoming a qualified operator. That’s why anyone using a PAT must carry a valid certification card, which verifies he or she has been thoroughly trained and tested on how to use that specific tool.
Depending on where you work, two types of certification apply. California has its own requirements, while the remaining 49 states have common certification. In California, certification is valid for only three years. Elsewhere, certifications last a lifetime.
When choosing a PAT, make sure you purchase from a reputable company. The tool should be UL-listed and fasteners approved by the International Conference of Building Officials (ICBO), Southern Building Code Congress International (SBCCI), and/or Miami-Dade County, Fla. To find out more about certification procedures, contact the manufacturer directly.
Staying safe. Even if you’re a certified operator, you should never attempt to operate any PAT until you’ve carefully read and understand the operating instructions. Is this precaution really necessary? Absolutely. Improper usage can cause serious injury or death. In addition to safety warnings, there is also valuable information in the operator’s manual on proper fastener length selection, how to determine if a base material is too hard or too soft, and how to select the appropriate powder load. Even if you think you know everything there is to know about PATs, read the instructions anyway. Taking this proactive approach can prevent many mishaps. But there’s more you can do to maximize the safety of you and your coworkers. Here are a few more tips to remember when using a PAT.
The power fasteners, or pins, are made of special alloy steel with a very specific heat-treating process to ensure the right mix of hardness, toughness, and ductility. Never use ordinary or concrete nails in any PAT. Borderlands 2: mechromancer domination pack crack servers.
PAT powder loads contain very precise amounts of special powder to maintain consistent driving performance. Make sure you use the correct powder load for your particular application. Powder loads are available in single shot (for .22 caliber tools) and 10-shot strips (for .27 caliber semi-automatic tools). The level of powder for each load is designated by its color and number. Once again, you should refer to the owner’s manual or application chart to determine the appropriate color and level powder load. Generally, the harder the base material, the more powder you need.
Before starting a job, always know the thickness and type of base material you’re fastening to and make sure you test fastenings starting with the lowest powder level. Never make fastenings in spalled or cracked areas or too close to an edge. Use a Spall Shield to help reduce the amount of surface chipping when fastening directly into concrete or sparking from directly fastening into steel.
Loading and usage tips. After choosing the correct load and fastener, insert the appropriate powder fastener into the muzzle of the tool head first, until the plastic collar is flush with the muzzle. Then insert the powder load into the tool. Always insert the fastener first, then the powder load. Once loaded, place the muzzle of the fastening tool against the work surface, holding it at a right angle.
Certain safety features have been designed to help prevent accidents. Before you can use the tool, you must completely compress the muzzle against the work surface until the sliding action of the barrel stops. This prevents the PAT from firing into the air or accidentally shooting into the body. Once you’ve loaded the tool correctly, observe the following precautions for additional safety:
Always wear ANSI-/OSHA-approved eye and ear protection.
Point the tool away from your body and others during loading or handling.
Do not put hand/fingers in front of the muzzle.
Always clear the work area on all sides and post appropriate warning signs to notify bystanders and coworkers.
Never fire a PAT in an explosive or flammable environment.
Prior to using a PAT, inspect the barrel to make sure it is free from obstructions.
Always unload a PAT before disassembling, assembling, replacing the barrel, or cleaning.
PATs are easy to use and provide quality performance and reliability for any user. But following strict safety precautions as well as keeping up on appropriate building codes and ANSI/OSHA standards in your area will increases your chances of a safe and efficient installation.

Powder-Actuated Tools Safety
Whenever you operate a powder-actuated tool (PAT), safe work practices must always be followed. These tools are designed to drive nails or other fastening devices into material such as concrete, steel, and masonry, which are not easily penetrated. These devices use explosive charges similar to a firearm. Since the charge is similar to a firearm, powder-actuated tools can “fire” nails and fastening devices into human flesh. Great respect for these tools and the safety precautions for them must be maintained.
Powder-actuated hand tools probably have as much safety built in to them as practically any tools on the market. In addition, manufacturers usually provide complete instructions and training for safe operation of the tools. These two factors alone should make the use of powder- actuated tools a safe operation. However, there are other precautions that have to be taken.

To start with, only trained, certified, and authorized personnel who are checked out in correct usage and safety should operate powder-actuated tools. And only tools, shields, and fasteners that meet state safety standard requirements for hand tools should be used.
A powder-actuated tool operates like a loaded gun so it should be handled with the same respect and safety precautions. When a job calls for a PAT, be sure to choose the correct cartridge for the fastener being used, then load the tool just before you intend to use it, keeping your hands clear of the open barrel end. Never carry a loaded PAT from job to job and don’t leave it unattended. As with a gun, always keep the tool pointed in a safe direction; never point it anyone.
Safety tips for powder-actuated tools:
The muzzle end of the powder-actuated tool must have a protective shield or a guard centered perpendicular to and concentric with the barrel to confine any projectile fragments and particles that could be launched when the tool is fired. If a tool has a high-velocity load, it must be designed not to fire unless it has this kind of safety device.
To prevent the powder-actuated tool from firing accidentally, tool designers developed these powerful tools with a protective feature that requires two separate motions, each of which must be done to fire the tool. The first motion brings the tool into the firing position, and the second motion pulls 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 greater than the total weight of the tool.
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. If it still will not fire, “Try it again, Sam!” Well, at least the part about holding it for another 30 seconds in the operating position. Then, instead of trying to fire it again, this time carefully remove the load according to manufacturer’s instructions. Following this procedure will lessen the likelihood of the faulty cartridge exploding. The bad cartridge must then be put in water immediately after removal.
If the powder-actuated tool develops a defect during use, it should be tagged and taken out of service immediately until properly repaired by a trained technician.
Safe practices for powder-actuated tools:
Before use, the operator must inspect to verify that the tool is clean, all moving parts operate freely, the barrel is free from obstructions, and correct shields, guards, or safety attachments recommended by the manufacturer are in place.
NEVER point a powder-actuated tool at anyone, whether it is loaded or unloaded! Handle as you would a firearm.
A powder-actuated tool should never be loaded until it is ready for use.
Any defective or poorly working tool should be immediately removed from service and tagged as unsafe.
Always wear proper personal protective equipment (PPE) when operating powder-actuated tools.
Powder-actuated tools should not be used in areas where flammable or combustible atmospheres may be present – the tool is a source of ignition and could cause an explosion.
When operating a powder-actuated tool, press and hold the tool firmly against the surface into which the fastening device is being driven.
Never drive a fastener into a “spalled” or chipped surface, such as an uneven area where a previous fastening was unsatisfactory.
- Never shoot a fastener into a surface unless you are certain it will contain the fastener. Take time to examine both the surface and the object being penetrated to assure your safety as well as the safety of others. The fastener can pass completely through the material and turn into a flying projectile.

Safe operation of powder-actuated tools demands knowledge and the operator’s constant caution. There are too many recorded cases of innocent co-workers being severely injured when powder-actuated hand tool safety practices were disregarded. Before each use of a powder-actuated tool, a complete job hazard analysis of the task should be completed and only trained personnel allowed to operate the equipment.
