Conclusion PPT-085-01 2 Introduction Nail guns are powerful, easy to operate, and boost productivity. They are also responsible for an estimated 37,00 emergency room visits each year. 68% of these visits involve workers. 32% involved are consumers. More than half of reported injuries are to the hand and fingers.

Know your Triggers Nail gun safety starts with understanding the various trigger mechanisms. How triggers differ o All nailers rely on two basic controls Finger trigger Contact safety tip
Four trigger types. PPT-085-01 11 Full Sequential Trigger This is the safest type of nail gun trigger. This trigger will only fire a nail when the controls are activated in a certain order. 1. Safety contact tip must be pushed into the work piece.
2. User squeezes the trigger to discharge a nail. PPT-085-01 12 Full Sequential Trigger Nails cannot be bump fired. Also known as single-shot trigger, restrictive trigger, or trigger fire mode.
PPT-085-01 13 Contact Trigger Fires a nail when the safety contact and trigger are activated in any order. You can push the safety contact tip first then squeeze the trigger, or you can squeeze the trigger first then push the safety contact tip. PPT-085-01 14
Contact Trigger All nails can be bump fired. Also known as bump trigger, multi-shot trigger, successive trigger, dual-action, touch trip, contact trip, and bottom fire. PPT-085-01 15 Single Sequential Trigger Like a full sequential trigger, this trigger will only fire when the controls are activated in a certain
order. The safety tip must be pushed into the work piece. Then, the user squeezes the trigger to discharge a nail. PPT-085-01 16 Single Sequential Trigger To fire a second nail, only the trigger must be released. The safety contact tip can stay pressed
into the work piece. Nails cannot be bump fired. PPT-085-01 17 Single Actuation Trigger Like the contact trigger, this trigger will fire a single nail when the safety contact and trigger are activated in any order.
The nail can be bump fired with a single actuation trigger but not with a true single sequential trigger. PPT-085-01 18 Single Actuation Trigger A second nail can be fired by releasing the trigger, moving the tool and squeezing the trigger again without releasing the safety contact tip.
PPT-085-01 19 Six Steps to Nail Gun Safety 1. Use the full sequential trigger The full sequential trigger is always the safest trigger mechanism for the job. At a minimum, provide full sequential trigger nailers for placement work.
Consider restricting inexperienced employees to full sequential trigger nail guns starting out. PPT-085-01 20 Six Steps to Nail Gun Safety 2. Provide training How nail guns work and how triggers differ.
Main causes of injuries especially differences among types of triggers. Instructions provided in manufacturer tool manuals and where the manual is kept. PPT-085-01 21 Six Steps to Nail Gun Safety
2. Provide training (cont.) Hands on training with the actual nail guns to be used on the job. How to load the nail gun. How to operate the air compressor. PPT-085-01 22 Six Steps to Nail Gun Safety 2. Provide training (cont.) How to fire the nail gun. How to hold the lumber during placement work. What to do when a nail gun malfunctions.
PPT-085-01 23 Six Steps to Nail Gun Safety 2. Provide training (cont.) How to recognize and approach ricochet-prone surfaces.
How to best handle special risks associated such as nail gun recoil and double fires. Training should also cover nail gun procedures, PPE, injury reporting, and first aid and medical treatment. PPT-085-01 24 Six Steps to Nail Gun Safety 3. Establish nail gun procedures
Make sure that tool manuals for the nailers used on the job are always available on the jobsite. Make sure the manufacturers tool labels and instructions are understood and followed. Check tools and power sources before operating to make sure they are in proper working order.
PPT-085-01 25 Six Steps to Nail Gun Safety 3. Establish nail gun procedures (cont.) Set up operations so that workers are not in the line of fire from nail guns being operated by co-workers. Check lumber surfaces before nailing. Look for knots, nails, straps, hangers, etc. that could cause recoil or ricochet. PPT-085-01
26 Six Steps to Nail Gun Safety 3. Establish nail gun procedures (cont.) Always disconnect the compressed air when: Leaving a nail gun unattended; Traveling up and down a ladder or stairs; Passing the nail gun to a co-worker; Clearing jammed nails; Performing maintenance on the nail gun. PPT-085-01 27
Six Steps to Nail Gun Safety 3. Establish nail gun procedures (cont.) For placement work, keeps hands at least 12 inches away from the nailing point at all times. Always shoot nail guns away from your body and away from your co-workers.
Take extra care when toe-nailing. PPT-085-01 28 Six Steps to Nail Gun Safety 3. Establish nail gun procedures (cont.) Use a hammer if you cannot reach the work while holding the nailer with your dominant hand.
Use a hammer or reposition for work at face or head height. Use a hammer or full sequential trigger nail gun when working in a tight space. PPT-085-01 29 Six Steps to Nail Gun Safety
3. Establish nail gun procedures (cont.) Set up jobs to minimize the need for nailing at height. Consider using scaffolds instead of ladders. Position ladders so you dont have to reach too far.
PPT-085-01 30 Six Steps to Nail Gun Safety 3. Establish nail gun procedures (cont.) NEVER bypass or disable nail gun safety features. NEVER lower the nail gun from above or drag the tool by the hose.
NEVER use the nail gun with the non-dominant hand. PPT-085-01 31 Six Steps to Nail Gun Safety 4. Provide Personal Protective Equipment (PPE) Safety Shoes High Impact eye protection (ANSI Z87.1) Hard Hats
Hearing protection PPT-085-01 32 Six Steps to Nail Gun Safety 5. Encourage reporting and discussion of injuries and close calls. Reporting helps ensure that employees get medical attention. It also helps to identify unrecognized job site risks.
Injuries and close calls provide teachable moments that can help improve crew safety. PPT-085-01 33 Six Steps to Nail Gun Safety 6. Provide First Aid and medical treatment Employers and workers should seek medical attention immediately after nail gun injuries. Studies suggest that 1 out of 4 nail gun hand injuries can involve some type of structural damage such as a bone fracture.
Seeking medical attention immediately can help avoid any complications that may occur from the injury. PPT-085-01 34 Other Hazards may Include Compressed Air Regulated under OSHA 29 CFR 1926.302(b) Noise Most nail gun manufacturers recommend that users wear hearing protection. Musculoskeletal Disorders Framing nail guns can weigh up to 8
pounds and many framing jobs require workers to hold and use these guns for long periods of time. PPT-085-01 35 Conclusion Nail gun injuries are painful. Some cases severe injuries or death. Nail gun injuries have been on the rise along with the increased popularity of these powerful tools. These injuries can be prevented, and more and more contractors are making changes to improve nail gun safety.
