WATERSUPPLY

Definition

The tactical operation of providing sufficient water to meet needed fire flows at fire incidents.

Principle of Water Supply

Develop water supply adequate to support all fireground operations.

Insert Slide #7 Module 4

Municipal Water Systems

• Know quantity of water available

• Learn how water is distributed

Insert Slide #9 Module 4

Municipal Water Systems (cont’d)

Select size and number of supply lines

Insert Slide #11 Module 4

Static Water Systems

• Preplan to locate sources

• Use relay pumping

Insert Slide #13 Module 4

Portable Water Sources

• Tanker/tender effectiveness

• Tanker delivery rate

Tanker Delivery Cycle

The time it takes a tanker/tender to set up, dump the water, travel to the fill site, fill up, and return to the dump site.

Insert Slide #16 Module 4

Setting Up Fill and Dump Sites

• Locate for best access

• Avoid backing up

• Assign water supply officer

What factors should be considered in a tactical sizeup for initiating water supply tactics?

Tactical Sizeup Considerations

• What are the fire flow needs?

• What source(s) will supply required flow?

• What delivery method will be used?

• What resources (apparatus, personnel, equipment) are needed?

• How long will it take to develop the water supply?

Tactical Sizeup Considerations(cont’d)

• How reliable is the water supply?

• Is there a backup supply available?

• Is any support required?

• What coordination with other tactics is needed?

• What safety concerns exists?

• How effective is the water supply system?

Water Supply Coordination

• Find out required fire flow from IC

• Coordinate with end users to assure adequate supply for all tactics

Develop a Water Supply Tactical Action Plan

• Determine critical sizeup factors

• Select water source(s)

• Select delivery method

Develop a Water Supply Tactical Action Plan (cont’d)

• Identify needed resources• Determine needed support• Determine needed coordination• Identify safety concerns

EXPOSUREPROTECTION

Definition

Tactical operations performed to protect exposed property and areas near the fire from becoming involved.

Principles of Exposure Protection

• Protect external exposures

• Protect internal exposures

• Protect areas downwind from the fire

Protect Vulnerable and Valuable Exposures

• Preplan

• Select and prioritize exposures

Insert Slide #28 Module 4

Protect Exposures

• Interior

• Exterior

Tactics for Protecting Exposures

• Provide adequate flow and put fire out

• Wash face of exposed building

• Push fire back into original building

• Reduce intensity or extinguish at critical points

Tactics for Protecting Exposurescont’d

• Use ventilation to draw fire away from exposures

• Stretch lines to inside of exposure

• Charge exposure sprinkler system

Brand Control

• Monitor weather conditions

• Assign teams to check roofs

Support for ExposureOperations

• Gaining entry to exposures

• Laddering of building

What factors must be considered in a tactical sizeup for exposure

protection?

Tactical Sizeup Considerations

• Is operating position outside collapse zone?

• What flow is available for exposure protection?

• What tactics are most appropriate?

• What number and size of hoselines or appliances are required?

Tactical Sizeup Considerationscont’d

• Where should lines or appliances be placed?

• Is any support required?

• What coordination is needed?

• What safety concerns exists?

• How effective is the exposure protection effort?

Coordination

• Ventilation

• Adequate water for exposures and fire building

• Prevent opposing hoselines

Exposure Protection TacticalAction Plan

• Determine critical sizeup factors

• Identify and prioritize interior and exterior exposures

• Determine water available for exposure protection

Exposure Protection TacticalAction Plan cont’d

• Select exposure protection tactics• Identify needed resources• Determine needed support• Determine needed coordination• Identify safety concerns

Summary

• Water supply operations and tactics are established to meet fire flow requirements at fire incidents

• Exposure protection tactics are designed to protect vulnerable and valuable property
