CWP Crew Leader Safety Orientation BE AN EXAMPLE, BE AN AUTHORITY. ABOVE ALL, BE SAFE.
Pneumatic Nailers
Outline Personal Protective Equipment
Operator Responsibilities Our Policy Working Around Nailers
Firing Nailers Air Hoses Compressors
Personal Protective Equipment (PPE) Mandatory PPE for pneumatic nailers: Hard hats Eye protection Volunteers/workers are welcome to provide their own safety glasses. Eye protection must be shatterproof lenses with OSHA-approved sidelens protection. Personal prescription and/or sunglasses are not acceptable substitutes. Hearing protection. Volunteers/workers are welcome to provide their own hearing protection. Hearing protection must be OSHA-approved ear plugs or ear muffs. These must be in use at all times while pneumatic nailers are in use– there is no “just a couple nails.”
General Safety Provisions with and around Pneumatic Nailers
As the operator, you are responsible for: Keeping your work area clear of debris and trip hazards. Ensuring the nailer is disabled whenever not in use. Maintaining safe hose placement and movement (not a trip hazard, not in
danger of being damaged, not knocking over tools/materials as you move). Maintaining a minimum six-foot safety radius around your nailing area. This includes six feet behind the surface you are nailing into. Maintaining safe compressor operation. Following all manufacturer guidelines for the safe operation and maintenance of the gun, compressor, and hose. Ensuring those working around you have appropriate hearing protection and are comfortable with your use of the nailer.
Tool Safety Pneumatic Nailers
Remember our Policy: Only trained HFHMD staff are authorized to use
framing nailers on site. Only trained HFHMD staff and specially designated
and trained volunteers are authorized to use trim nailers on site.
Tool Safety Pneumatic Nailers
Working with and around nailers: Follow all manufacturer specifications for air pressure, nail size
and style, oiling and maintenance, and safe loading and operating practices. Clearly communicate the potential danger to all workers present and establish a minimum six-foot safety radius.
Verify that no individual is directly behind the material being fastened.
Do not leave pneumatic nailer unattended while attached to hose. Always remove finger from trigger when not driving fasteners. Always assume the nailer contains fasteners. Keep the nailer pointed away from yourself and others. Absolutely no horseplay. Do not shoot nails at targets or people. Always place yourself in a firmly balanced position when using
the nailer, especially on ladders. Never use any part of the tool as a hammer.
Tool Safety Pneumatic Nailers
Firing Pneumatic Nailers: Do not fire the nailer unless the yoke is firmly pressed against the material. Do not try to drive nails into material too hard to penetrate; pay special
attention to knots in lumber. Do not drive fasteners on top of other fasteners or with the tool at too steep of an angle; the fasteners can ricochet. Only use sequential tip triggers which require contact with the surface and pulling of the trigger in order to fire.
Do not use contact tip triggers, which will fire upon surface contact.
Do not drive fasteners close to the edge of the work surface.
The material can split, which allows pieces to fly free and the fastener to shoot completely through.
Keep your free hand safely away from nailer.
This includes at least six inches clearance on the back of the material as well as to each side of the tool on the nailing surface in the event that the fastener curls in the material and comes back through the surface.
Tool Safety Pneumatic Air Hoses
Air Hoses Disconnect the air hose before clearing a jam or making an adjustment. When detaching a nailer from a hose or a hose from a compressor,
maintain a firm grip on the hose end.
A hose releasing pressure can easily slip from your hand and cause serious injury. Use caution when disconnecting hoses—released air raises dust and debris at high speeds.
Examine the entire length of the air hose before use; look for swollen
sections and cuts in the sheath.
When you first connect hose to compressor and nailer, listen for any slow leaks around connections. Do not use or attempt to repair a damaged air hose on site.
Never pull, lift or swing a nailer by the hose.
This could cause misfires and/or damage to the equipment.
Do not fasten air hoses with staples, nails, or suspend by wire. Do not run air hoses through metal or other sharp openings without
padding.
Tool Safety Air compressors
Air compressors Follow all manufacturers’ specifications for air
compressor maintenance and operation.
Pay special attention to compressors requiring oil; check oil level frequently.
Drain compressor after every use.
For dual-tank compressors, drain each tank. For compressors where drainage outlet isn’t centered directly at bottom of tank, tilt tank as it drains to force condensed water out. Condensed water allowed to pool in the tank will eventually rust out the chamber and can lead to a pressurized explosion.
Tool Safety Air compressors
Setting pressure on the tank:
Follow all manufacturer specifications regarding pressure limits for every pneumatic gun.
Most nailers will list these limits directly on the side of the gun.
Wait until compressor tank has filled and cycled off before adjusting hose pressure. Readjust as necessary after initial use to determine if nailer requires more or less pressure to effectively and safely drive fasteners. Only adjust by 5psi at a time while determining the appropriate pressure for each use.
Always connect compressor as close as possible to a
direct power source.
It is preferable to run a long air hose rather than a long extension cord.
Always connect compressors to a GFCI-protected outlet, paying special attention to this rule while working in a trimmed house.
On-Site Orientation
Remember, there will be a mandatory pneumatic
tool orientation for all crew leaders and skilled volunteers who will be operating nailers. This will be conducted Monday morning before
volunteers arrive on site.
