Which SCBA limitation might result in excess air loss from the cylinder?

The limitation related to excess air loss from the cylinder primarily stems from poor apparatus condition. When the SCBA (Self-Contained Breathing Apparatus) is not maintained properly, components may deteriorate or become damaged, leading to leaks. These leaks can occur in several areas, such as the cylinder valve, hoses, or connections. If the integrity of the apparatus is compromised due to wear and tear, age, or inadequate storage practices, it can lead to a significant loss of the air supply, which is critical for effective use in hazardous environments.

Maintaining the SCBA in good working order is essential for ensuring that it functions properly during emergencies. Regular inspections and repairs, according to the manufacturer’s guidelines, can help prevent these types of issues, ensuring that firefighters can rely on their SCBA to provide the necessary air supply in dangerous situations.
