Canadian Restricted and Non-Restricted Firearm Safety (CRFSC) Practice Exam

Question: 1 / 400

What can be a consequence of having oil or dirt in a firearm?

Increased accuracy during firing

Reduced need for maintenance

Increased pressure that may cause the barrel to burst

Having oil or dirt in a firearm can lead to increased pressure that may cause the barrel to burst. This occurs because any obstruction, including excessive oil, dirt, or fouling material, can impede the normal operation of a firearm. When a shot is fired, gases expand rapidly. If the barrel is obstructed, the pressure builds up significantly as the gases cannot escape freely. This elevated pressure can exceed the structural limits of the barrel, potentially leading to a dangerous situation such as a burst or catastrophic failure.

Understanding the maintenance and cleanliness of a firearm is crucial for safety and performance. Regular cleaning ensures that any residue or contaminants are removed, allowing the firearm to function safely and effectively. Keep in mind that maintenance is essential for the reliable operation of firearms, and neglecting to address dirt or oil can lead to serious safety hazards.
