Which of the following actions should be taken while cleaning hose?

Working the female swivel back and forth to ensure smooth operation is crucial during the cleaning and maintenance of fire hoses. This action helps to dislodge any debris, dirt, or buildup that may be impairing the connection of the hose. Regularly maintaining the swivel ensures that it operates correctly and can be easily connected or disconnected from other hoses or fittings. Smooth operation of the swivel is essential for the efficiency and safety of firefighting operations, as a malfunction can lead to leaks or difficulty in hose management during critical situations.

Other methods mentioned may not provide the same level of maintenance. For example, simply drying the hose with a towel might not effectively clean it, as it doesn’t address potential internal issues where contaminants could be lodged. Using a pressure washer may not be suitable for all hoses, as it could damage or unnecessarily wear out the material. Submerging the hose in cold water could help in some cleaning aspects, but it may not thoroughly ensure that all moving parts like swivels are actively maintained to prevent future issues.
