At what minimum supply pressure do pneumatically driven nailers with automatic fastener feeds require a safety muzzle?

1. 30 psi

2. more than 100 psi

3. 50 psi

4. 80 psi

The correct answer is: more than 100 psi

Pneumatically driven nailers with automatic fastener feeds operate under specific safety regulations to mitigate the risk of injury to the operator and others on the job site. The requirement for a safety muzzle is particularly important when the nailer is operating at higher pressures. When the supply pressure exceeds the threshold of 100 psi, it becomes critical to implement safety features such as a safety muzzle. This is because operating at these higher pressures increases the risk of the fasteners being expelled with greater force, which can lead to more severe injuries in case of a malfunction or misfire. Understanding these safety specifications is vital for ensuring a safe work environment when using pneumatic tools, particularly in construction settings where the risk of accidents can be elevated.
