Underwriters Laboratory factory

If it becomes necessary to fill a gasoline or diesel fuel lift truck with a portable container, only UL/FM (Underwriters Laboratory/Factory Mutual) cans may be used. The can must have the proper pouring spout to avoid fuel spillage. 

Fire and Wind Hazards. Weather resistance of roof covetings is not necessarily correlated to fire and wiad resistance. Underwriters Laboratory and the Factory Mutual System test and rate fire and wiad hazard resistance, and some durabiUty tests. Organic felt or fiber glass mat base shingles are commonly manufactured to meet minimum UL requirements, which, ia addition to minimum mass, require wiad and fire resistance properties. 

Underwriters Laboratories Inc. (UL) and Factory Mntnal Research (FM) will condnct tests for flame arrester mannfactnrers to ascertain if a designated flame arrester (deflagration or detonation type) will prevent passage of a flame of a specific gas. Both UL and FM test procednres also inclnde tests for endnrance bnrning, and in the case of UL tests, also for continnons flames. 

Certification. It is a benefit to the employer to ensure that the intrinsically safe electrical circuit is certified. Certification can be achieved through the use of a third party, such as Underwriters Laboratories or Factory Mutual Research. Both of these organizations have their own standards for approval which are based on NFPA 493. The certification is accomplished in three steps ... 

Listed equipment is typically defined as materials that have been tested to a standard by an organization that is acceptable to the AHJ. The listing organization, such as Underwriters Laboratories (UL) or Factory Mutual (FM), maintains a periodic audit of listed equipment or materials to ensure that the equipment or material meets appropriate designated standards or has been tested and found suitable for a specified purpose. The testing organization then publishes a list of equipment that has passed the evaluation process. Hence, the fire protection community uses the term "listed" to define equipment that has been specifically evaluated for use in fire protection applications. 

A successful factory-applied intumescent paint has been developed by the Celotex Corp. for application to acoustic board. In addition, a satisfactory package paint, Due-Tex flame-retardant paint, is available for application over old fiberboard installations, wood, etc. This product bears an Underwriters Laboratories label. 

Many tests have been devised to evaluate the fire and flame resistance of surface-treated acoustical fiberboard. The most widely accepted test, recognized by both the building industry and the building code agencies, is the fire-resistance test specified in federal specification (3). Other tests under consideration, but not universally adopted, are the tunnel test of the Underwriters Laboratories, Inc. (11), and the Factory Mutual room burn out test (2). A small scale test that is being employed for plant control and quick finish evaluation is the Class F fire test (12). 

Every laboratory facility should be equipped with at least a manually activated alarm system, although an automatic system is preferable since it wiU continue to function when the facility is unoccupied. Automatic alarms are especially useful in academic institutions since there are break periods when the population of the campus is very low. In many cases, depending upon local code requirements and the occupancy classification, an automatic fire alarm system may be required rather than optional. Every component of a system should be approved by Underwriters Laboratories, the Factory Mutual System, or other nationally recognized accrediting and testing organizations. 

Term used by national or local codes to denote equipment, devices, tools, or systems meeting acceptable standards of safety performance for a particular purpose as verified by a recognized testing or professional agency. See also Classified Factory Mutual (FM) Labeled Listed Underwriters Laboratories (UL). 

Products or materials that are specified for use which meet standard test requirements for fire safety concerns. Standard test conditions are usually set by national or local code requirements and verified through independent testing laboratories (e.g., UL or FM). See also Approved Factory Mutual Labeled Listed Underwriters Laboratories (UL). 

Equipment or materials to which is attached a specified label, symbol, or other identifying mark of an inspection agency, nationally recognized testing laboratory, or organization acceptable to the authority having jurisdietion and coneerned with product evaluation that maintains periodic inspection of the production of labeled equipment or materials. The provision of a label by the manufacturer on a fire proteetion product indicates compliance with appropriate standards or performance in a speeified manner for fire safety. See also Approved Classified Factory Mutual (FM) Listed Underwriters Laboratories (UL). 

Organizations such as Underwriters Laboratory and FM Global (formerly Factory Mutual System) offer publications and services that draw on years of experience with hazards in facility designs. 

Equipment that has been listed or approved by a nationally recognized testing laboratory such as Factory Mutual Engineering Corp., or Underwriters Laboratories, Inc., or Federal agencies such as Bureau of Mines, or U.S. Coast Guard, which issue approvals for such equipment. 

UL stands for Underwriters Laboratories Inc. FM stands for Factory Mutual Systems.

OSHA defines a container as any can, barrel, drum, or tank however, that container must approved. OSHA defines an approved container as one that is acceptable to the authority enforcing the code. This would include containers allowed by the Department of Transportation (DOT) or containers that are listed and labeled with an approval from Underwriter s Laboratory, Factory Mutual, or other Nationally Recognized Testing Laboratory. 

Central Station. The central station supervisory system has been the norm in the semiconductor industry. The size of the semiconductor facility warrants the reliability that comes with this level of protection. Equipment is specifically listed for this type of service. Signals from the devices are sent to a remote location approved by Factory Mutual or listed by Underwriters Laboratory. Upon receipt of a fire signal, a central station must alert the fire department. 

The United States has two nationally accepted codes the National Fire Protection Association s Lightning Protection Code (ANSI C5. 1), and the Underwriter s Laboratories Master Labeled Lightning Protection System (Standard UL 96A). The requirements of these two codes are quite similar and are probably equally utilized on structures throughout the nation. The major difference between the two is that the Master Label can be certified upon both a factory inspection and labeling of the lightning protection materials and upon performance of a field inspection by an authorized inspector. 

Fire resistance rated wall assemblies are tested and listed by nationally recognized testing laboratories such as Underwriter s Laboratories, Wamock-Hersey or Factory Mutual. These listings are published in each organization s listing directory or approval guide.
