Controlled substance definition

Worker safety studies are not likely to normally include a control substance (i.e., a material used in the study to serve as basis of comparison with the test substance). However, if a control substance is included as a treatment group, then it must (1) be fully characterized as to its identity, purity (or strength), and stability (and solubility, if appropriate) (2) be appropriately tested in mixtures with any carrier used and (3) meet all the other GLP recordkeeping, labeling, and storage requirements, as specified for the test substance. There is some regulatory relief here, however, in that water, by definition, is excluded from being considered a control substance, and vehicles (those substances added to enhance solubilization or dispersion of the test substance) are addressed separately in the FIFRA GLP Standards. 

Here is a masterpiece of logic which makes some sense out of sloppy law. It must be remembered that the purpose of all of this is to determine if one, or two, or three definitions must be applied to establish just what is an analogue. This court declared that a substance may be a controlled substance analogue only if it satisfies clause (i) and at least one of clauses (ii) or (iii). 

The EPA GEPs for both the TSCA and the FIFRA have basically the same definitions for control substances and reference substances. A control substance means any chemical substance or mixture, or any other material other than a test substance, feed, or water, that is administered to the test system in the course of a study for the purpose of establishing a basis for comparison with the test substance for chemical or biological measurements. A reference substance means any chemical substance or mixture, or analytical standard, or material other than a test substance, feed, or water, that is administered to or used in analyzing the test system in the course of a study for the purposes of establishing a basis for comparison with the test substance for known chemical or biological measurements. ... 

Reportable Excess Property excess property that is reportable to the GSA by the holding agency (see definition) on Standard Form 120, excluding Hazardous Waste (see definition). Extremely Hazardous Property (see definition). Scrap (see definition). Controlled substances. Chemicals determined to be appropriate for abandonment or destruction. Nuclear-related and Proliferation-sensitive Property (see definition). National security-sensitive property, NRC-controlled materials, etc. Reportable excess property includes non-hazardous chemicals, drugs and reagents other than controlled substances nonifiable asbestos materials, excluded PCB products (i.e., those containing less than 49 ppm PCBs), etc.. 

A list of controlled substances will depend on their toxicity and stability in the environment, technological processes of destruction and utilisation and may be definitely determined only after preliminary laboratory studies on the primary means of WA migration and transformation and establishment of their main transformation products. 

An explanation of what constitutes a refusal to submit to an alcohol or controlled substances test and the attendant consequences. (8) This part of your written policy can be taken right out of the regulations. Your written policy must state what the organization considers a refusal to be tested. For this element, go to the definition of refuse to submit under 382.107, and simply incorporate the nine definitions of refusal into your written policy. In addition, you must state what the consequences are to a driver who refuses to be tested. 

Actual knowledge means actual knowledge by an employer that a driver has used alcohol or controlled substances based on the employer s direct observation of the driver, information provided by the driver s previous employer(s), a traffic citation for driving a CMV while under the influence of alcohol or a controlled substance, or a driver s admission of alcohol or controlled substance use under the provisions of Sec. 382.121. Direct observation as used in this definition means observation of alcohol or controlled substance use and does not include observation of driver behavior or physical characteristics sufficient to warrant reasonable suspicion testing under Sec. 382.307. 

The potentiometry sensor (ion-selective electrode) controls application for determination of polymeric surface-active substances now gets the increasing value. Potentiometry sensor controls are actively used due to simple instmment registration, a wide range of determined concentrations, and opportunity of continuous substances contents definition. That less, the ionometry application for the cation polymeric SAS analysis in a solution is limited by complexity of polycation charge determination and ion-exchanger synthesis. 

Terminology The International Standards Organization has recently defined a corrosion inhibitor as a chemical substance which decreases the corrosion rate when present in the corrosion system at a suitable concentration, without significantly changing the concentration of any other corrosive agent. This last point is significant since it excludes chemicals employed for deaeration or pH control from the definition of a corrosion inhibitor. On the other hand, it should be noted that the inhibitor is .. . present in the corrosion system. . . , and thus arsenic when added to brasses to prevent dezin-cihcation may be classified as an inhibitor.
