How often shall all system hoses be examined for damage?

• A. Annually
• B. Monthly
• C. Every 3 years
• D. Every 5 years

Answer: (A)

Regular inspection of system hoses for physical damage is required at least annually to ensure the discharge path remains intact and free of leaks. Hoses are flexible components that can crack, wear, or become abraded from movement, vibration, or handling. Damaged hoses can lead to leaks or reduced agent discharge, potentially leaving the protected space without full protection when needed. Checking them once a year provides a practical, dependable safeguard without overburdening maintenance schedules. Monthly checks would be more frequent than necessary for typical hose wear, while intervals of several years risk undiscovered damage that could compromise system performance during an actuation.
