Traffic control device means a flagger, sign, signal, marking, or other device used to regulate, warn or guide traffic, placed on, over, or adjacent to a street, highway, private road open to public travel, pedestrian facility, or shared-use path by authority of a public agency or official having jurisdiction, or, in the case of a private road open to public travel, by authority of the private owner or private official having jurisdiction.
Control device means equipment (such as an incinerator or carbon adsorber) used to reduce, by destruction or removal, the amount of air contaminants in an air stream prior to discharge to the ambient air.
Traffic control signal means a device, whether manually, electrically, or mechanically operated, by which traffic is alternately directed to stop and permitted to proceed.
Semiconductor cleanrooms means the integrated systems, fixtures, piping, partitions, flooring,
Synchronous Optical Network (SONET) is an optical interface standard that allows inter-networking of transmission products from multiple vendors. The base rate is 51.84 Mbps (“OC-1/STS-1”) and higher rates are direct multiples of the base rate, up to 13.22 Gbps.
Synchronous Optical Network (SONET means the optical interface standard that allows inter-networking of transmission products from multiple vendors. The base rate is 51.84 Mbps (“OC 1/STS 1”) and higher rates are direct multiples of the base rate, up to 13.22 Gbps.
Secondary dose monitoring system means a system which will terminate irradiation in the event of failure of the primary dose monitoring system.
Assistive technology device means any item, piece of equipment, or product system that is used to increase, maintain, or improve the functional capacities of a child with a disability.
Primary dose monitoring system means a system which will monitor the useful beam during irradiation and which will terminate irradiation when a pre-selected number of dose monitor units have been delivered.
Backflow prevention device means a safety device used to prevent pollution or contamination of the water supply due to the reverse flow of water from the irrigation system.
Semiconductor equipment means (i) machinery or tools or repair parts or replacements thereof; (ii)
Controlled substance analog means a substance the chemical structure of which is substantially
Cabinet x-ray system means an x-ray system with the x-ray tube installed in an enclosure independent of existing architectural structures except the floor on which it may be placed. The cabinet x-ray system is intended to contain at least that portion of a material being irradiated, provide radiation attenuation, and exclude personnel from its interior during generation of radiation. Included are all x-ray systems designed primarily for the inspection of carry-on baggage at airline, railroad, and bus terminals, and in similar facilities. An x-ray tube used within a shielded part of a building, or x-ray equipment that may temporarily or occasionally incorporate portable shielding, is not considered a cabinet x-ray system.
Acceptable earned value management system means an earned value management system that generally complies with system criteria in paragraph (b) of this clause.
Continuous parameter monitoring system or "CPMS" means all of the equipment necessary to meet the data acquisition and availability requirements of this chapter, to monitor process and control device operational parameters (for example, control device secondary voltages and electric currents) and other information (for example, gas flow rate, oxygen or carbon dioxide concentrations), and to record average operational parameter value on a continuous basis.
Beam monitoring system means a system designed and installed in the radiation head to detect and measure the radiation present in the useful beam.
Earned value management system means an earned value management system that complies with the earned value management system guidelines in the ANSI/EIA-748.
Individual monitoring devices means devices designed to be worn by a single individual for the assessment of dose equivalent. For purposes of these regulations, "personnel dosimeter" and "dosimeter" are equivalent terms. Examples of individual monitoring devices are film badges, thermoluminescent dosimeters (TLDs), pocket ionization chambers, optically stimulated luminescence (OSL) dosimeters and personal air sampling devices.
Continuous parameter monitoring system (CPMS means all of the equipment necessary to meet the data acquisition and availability requirements of the Prevention of Significant Deterioration program, to monitor process and control device operational parameters (for example, control device secondary voltages and electric currents) and other information (for example, gas flow rate, O2 or CO2 concentrations), and to record average operational parameter value(s) on a continuous basis.
Control apparatus means any device which prevents or controls the emission of any air contaminant directly or indirectly into the outdoor atmosphere.
