National Fire Protection Association (NFPA), NFPA 14. Installation of Standpipe and Hose Systems. NFPA, Quincy, MA, 1993. 

For large laboratory buildings of two or more stories, standpipes should be installed in accordance with NFPA 14, Standard for the Installation of Standpipe, Private Hydrant, and Hose Systems. Hose lines of an approved type should be provided. 

Spill containment is required around the marine vessel during loading and unloadingto prevent the spread of an accidental release. Means should be provided to manage small spills that may occur during transfer arm or hose system connection, disconnection or draining.

Closed-loop systems. In closed-loop systems, groundwater abstraction is not required. Such systems can be used in poorly permeable formations, such as hard rocks or clays. Closed-loop systems may be direct circulation where the heat pump refrigerant is pumped through a closed loop installed in the ground. More frequently they utilize indirect circulation. Here, water, usually with added anti-freeze (e.g., ethylene glycol or ethanol), is circulated through a closed polyethene hose system (the collector... 

This compressed air system had supplied air with undesirable moisture content for a number of years. For several years prior to this incident this small air system was idle. Innovators decided to use compressed, dry air to purge out the moisture and cool down the hot unit after it achieved the appropriate temperature. They first used hoses to connect to a dry air system, and this improvement led to better dew points and longer dryer cycles. The temporary hose system seemed so beneficial that it was replaced with piping. (See Figure 2—20.)... 

NFPA 45, 4.1-4.6 4.3.3 All laboratory units shall be provided with fire protection appropriate to the fire hazard, including automatic fire extinguishing systems, standpipe and hose systems, portable fire extinguishers, fire alarm systems, fire prevention programs, and emergency plans. 

The HOSE system, developed by Bremser and his co-workers at BASF, used slightly smaller fragments the second neighbours are not always taken into account, but the concentric environment of each atom is used for structure description of the molecule. 

The hose systems wUl be replaced with fixed piping. 

There are several modern methods and devices for use by emergency response personnel or others involved with spill control efforts to safely apply spill control agents to control spilled material hazards. These include portable pressurized applicators similar to hand-held portable fire extinguishing devices, and nozzle and hose systems similar to portable fire fighting foam systems which allow the operator to apply the agent without having to come into contad with the spilled material. The operator is able to apply the agent to the spilled material from a remote position. 

For temporary piping and hose systems, make sure the hoses are free of cuts and fittings are not damaged. All joint restraint cables are in place.
