Safety
As with their air-actuated cousins, powder-actuated guns have a muzzle safety interlock. If the muzzle is not pressed against a surface with sufficient force, the firing pin is blocked and cannot reach the load to fire it. This ensures that the gun does not discharge in an unsafe manner, causing the nail to become a projectile. Nonetheless, good judgment should always be used when using a powder-actuated nail gun, since the nail is driven with far more force than an air-actuated gun. The surface being nailed should, therefore, certainly be capable of stopping and holding the nail.
Most manufacturers of powder-actuated nail guns offer training and certification. Many projects and employers require this before an employee is permitted to use the tool.
The ownership and use of these tools is regulated in Australia. The owner has to register the tool, and an operator of one of these tools is required to have a license and to have undergone training in their use. These laws are in keeping with Australia's extremely strict firearm laws.
In the US, failure to properly dispose of charges is a common OSHA safety violation. Training is required by OSHA before someone can use the tool on a jobsite.

Famous quotes containing the word safety:
“An evident principle ... is the principle of justice to all peoples and nationalities, and their right to live on equal terms of liberty and safety with one another, whether they be strong or weak.”
—Woodrow Wilson (1856–1924)
“To emancipate [the slaves] entirely throughout the Union cannot, I conceive, be thought of, consistently with the safety of the country.”
—Frances Trollope (1780–1863)
“Once women begin to question the inevitability of their subordination and to reject the conventions formerly associated with it, they can no longer retreat to the safety of those conventions. The woman who rejects the stereotype of feminine weakness and dependence can no longer find much comfort in the cliché that all men are beasts. She has no choice except to believe, on the contrary, that men are human beings, and she finds it hard to forgive them when they act like animals.”
—Christopher Lasch (b. 1932)
