Here are some safety precautions you should take when using 21 degree paper collated framing nails:
Wear eye protection.
Nails and nail guns can eject debris that can damage eyes. Safety glasses or goggles are recommended.
Wear dust mask.
Collated nails can generate dust during use. A dust mask will help prevent inhaling dust particles.
Wear thick work gloves.
The gloves will protect your hands from getting punctured by nails during handling and use.
Check nail gun for safety features.
Make sure the nail gun you are using has features like automatic safety stops to prevent accidental firing. Inspect the air hose for leaks or damage.
Test fire nails first.
Before nailing any real work, test fire a few nails into a dummy target to make sure the nail gun is operating properly. This helps prevent any misfires when you start nailing actual work.
Watch your fingers.
Be careful not to place fingers near the nail discharge point of the nail gun. Maintain proper hand placement while firing the nails.
Don’t overdrive nails.
Stop applying pressure when the nail is flush with or just above the surface. Overdriving can damage the nail gun or cause the nail to bend.
Those are some basic precautions to take to safely use 21 degree paper collated framing nails. Make sure to read and follow all safety warnings that come with your specific nail gun as well. Using safety equipment and practicing good technique will help prevent injuries.
