Study Notes
Water Supply Operations Overview
- Importance of establishing a reliable water supply for effective fire suppression within 30 seconds.
- Critical flow rate is essential for fire suppression; optimal rule of thumb is 500 GPM.
- Stream placement may require multiple smaller lines instead of one large line.
- MCFRS employs surface cooling techniques rather than gas cooling for residential fires.
- Class A Foam is used to enhance cooling by lowering water's surface tension; typically mixed at 0.025% with water.
Urban Water Supply Operations
- Utilizes fire hydrants with two units dedicated to water supply for operational redundancy.
- A rear independent water supply is less likely to disrupt water access in front.
- The 5th due engines implement strategies to resolve water supply deficiencies.
- Forward laying of hose is preferred, ensuring that second supply does not hinder the first.
- Heavy water connections preferred; 4-inch hoses are used over 3-inch for better flow.
- The first engine should establish the initial water link to hydrants using soft sleeves.
Rural Water Supply Operations
- Lack of hydrants leads to longer times to establish a sustainable water supply.
- Requires careful application of water to effectively manage burning surfaces.
- If the fire outgrows the initial attack, a Water Supply Officer (WSO) should be appointed.
- Attack Tanker Operations involve first and second due engines using a clappered siamese connection for a supply of 4,000 - 5,000 gallons.
- Water supply strategies must adapt to constraints, emphasizing life safety and property protection first.
General Operational Guidelines
- Uninterrupted water supply must be initiated and expandable for structure fires.
- First and third engines should provide water supply instructions en route to incidents.
- Specific strategies and tactics must align with water availability, emphasizing life safety and stabilization.
- Class A foam should be considered during the initial attack phase.
Specific Guidelines for Urban Situations
- First engine must charge fire control systems promptly while second units charge additional connections.
- If the first engine establishes a dual line, the third does not need to duplicate the setup.
- Focus on efficient use of water supplies while maintaining a tactical flow.
Specific Guidelines for Rural Situations
- The first engine should announce fill site locations, and ECC should document these for reference.
- Fill sites should ideally provide a minimum flow rate of 1,000 GPM for tankers.
- Engine use for filling tankers is essential, especially when hydrants are unavailable.
- Avoid ambiguous terminology for fill sites; specific designations enhance clarity.
Water Supply Expansion Operations
- If initial water sources are insufficient, static sources should be utilized for drafting and pumping.
- Water-carrying apparatus should operate in unison to establish an effective water supply.
