Final answer:
The duration a fire suppression agent can provide fire suppression in case of cargo smoke varies based on the agent type, system design, and volume of the space. Halon and other agents extinguish fires in seconds, but specifics are given by the system's manufacturer.
Step-by-step explanation:
The duration of fire suppression provided by an agent for dealing with cargo smoke varies depending on the type of fire suppression system installed, the volume of the protected space, and the nature of the fire-suppressing agent used. Typically, fire suppression systems in cargo areas are designed to discharge the agent long enough to extinguish the fire and prevent reignition. For example, halon, a common fire-suppressing agent, can extinguish a fire within seconds. However, newer systems using alternative agents due to environmental concerns may operate differently.
Factors affecting fire suppression duration:
Type of agent: The chemical properties of the suppression agent affect the duration and effectiveness of fire suppression.
System design: Systems are engineered to provide enough agent to suppress a fire for a calculated period, which could be a few minutes or longer, depending on the system's capacity and the objectives of the fire suppression system.
Space volume: Larger cargo areas may require longer discharge times to ensure complete fire suppression.
Specific information about discharge times is often provided by the manufacturer of the fire suppression system and can be found in the system's datasheet or operational manual.
