HSFE80-17-R-0001 Tank & Pump System Requirements

PART 1. OVERVIEW

1.1. A key part of the Federal Emergency Management Agency’s (FEMA) mission is to assist disaster survivors to recover from the event and move toward returning to their pre-disaster status as quickly as possible. As part of the recovery effort, FEMA assists survivors in moving from shelters to temporary housing as quickly as possible. FEMA’s mission covers the entire United States and territories.

1.2. One of the options that FEMA uses within the contiguous U.S. for temporary housing is manufactured homes. Manufactured homes are built to comply with 24 CFR 3280, the

Manufactured Home Construction and Safety Standard (the Standard). The Standard is silent on the inclusion of residential fire sprinklers.

1.3. FEMA has determined that the agency will equip manufactured housing units (MHUs) used as temporary housing with residential fire sprinkler systems. The sprinkler systems are in compliance with National Fire Protection Association (NFPA) Standard for the

Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured

Homes - NFPA 13D.

1.4. FEMA has determined that an external Tank and Pump System (TPS) will be provided with the MHU to ensure a consistent and adequate water supply. The TPS will provide adequate water flow, pressure and quantity to meet the operational requirements set forth by FEMA and in NFPA 13D.

1.5. FEMA has developed requirements for the TPS that will allow the MHU manufacturers to plan the 13D sprinkler system. The TPS requirements will have water pressure and flow requirements, an environmental envelop, water capacity minimums, maximum electrical power available, transportation requirements, and specific connections for electricity and water.

1.6. All FEMA MHUs are less than 2,000 square feet.

1.7. FEMA can use this contract to meet requirements of the manufactured home mission or any other legal mission assigned to FEMA including missions using the Economy Act.

Cam locks also called Cam and groove coupling, a kind of Hose coupling used to rapidly connect and disconnect fitting on piping or hose, they come in a variety of materials to be used with different liquids and a variety of sizes to accommodate hose or piping diameter. Cam locks uses

ANSI A-A-59326 formerly Military Specification MIL-C-27487.

Cam lock fasteners are categorized as:

Type "A", has a male camlock end and a female pipe thread (NPT thread) of the same size.

Type "B", has a female camlock end and a male pipe thread of the same size.

Type "C", has a female camlock end and a male hose tail on the other.

Type "D", has a female camlock end and a female pipe thread of the same size.

Type "E", has a male camlock end and a male hose tail on the other.

Type "F", has a male camlock end and a male pipe thread of the same size.
