| safety | 1. The condition or state of being safe; freedom from danger or hazard; exemption from hurt, injury, or loss. "Up led by thee, Into the heaven I have presumed, An earthly guest . . . With like safety guided down, Return me to my native element." (Milton) 2. Freedom from whatever exposes one to danger or from libility to cause danger or harm; safeness; hence, the quality of making safe or secure, or of giving confidence, justifying trust, insuring against harm or loss, etc. "Would there were any safety in thy sex, That I might put a thousand sorrows off." (Beau. & Fl) 3. Preservation from escape; close custody. "Imprison him, . . . Deliver him to safety; and return." (Shak) 4. Same as Safety touchdown, below. <chemistry> Safety arch, a tube to prevent explosion, or to control delivery of gases by an automatic valvular connection with the outer air; especially, a bent funnel tube with bulbs for adding those reagents which produce unpleasant fumes or violent effervescence. Safety valve, a valve which is held shut by a spring or weight and opens automatically to permit the escape of steam, or confined gas, water, etc, from a boiler, or other vessel, when the pressure becomes too great for safety; also, sometimes, a similar valve opening inward to admit air to a vessel in which the pressure is less than that of the atmosphere, to prevent collapse.

| safety factor | <radiobiology> The number of times a field line goes around a torus the long way for each time around the short way. In a tokamak, this number is typically near unity in the centre of the plasma and between two and 6 or 8 at the edge. So-called because it helps to determine the degree of stability the plasma has against certain instabilities. The safety factor is the inverse of the rotational transform, and can be expressed mathematically as q = (r Bt)/(R Bp), where r and R are the minor and major radii of the torus, and Bt and Bp are the toroidal and poloidal magnetic fields.

| safety lens | A lens that meets government specifications of impact resistance; the increased impact resistance required for safety lens's is obtained by tempering, by an ion-exchange process, or by using laminated or plastic lenses. (05 Mar 2000) |
| safety management | The development of systems to prevent accidents, injuries, and other adverse occurrences in an institutional setting. The concept includes prevention or reduction of adverse events or incidents involving employees, patients, or facilities. Examples include plans to reduce injuries from falls or plans for fire safety to promote a safe institutional environment. (12 Dec 1998) |
| safety spectacles | Spectacles which protect against ultraviolet or infrared rays or against mechanical injuries. Synonym: safety spectacles. (05 Mar 2000) |
| safety strap | <dentistry> A plastic strap which prevents a face-bow from coming loose and hurting you. (08 Jan 1998) |
| national institute for occupational safety and health | An institute of the centres for disease control and prevention which is responsible for assuring safe and healthful working conditions and for developing standards of safety and health. Research activities are carried out pertinent to these goals. (12 Dec 1998) |
| occupational safety and health administration | One of the U.S. Agencies responsible for regulation of biotechnology. The major law under which the agency has regulatory powers is the Occupational Safety and Health act. (09 Oct 1997) |

| ACE level | <investigation> This is a blood test which measures the concentration of angiotensin-converting enzyme (ACE) in the bloodstream. Elevations in angiotensin-converting enzyme are seen sarcoidosis, histoplasmosis, alcoholic cirrhosis, asbestosis, berylliosis, diabetes, Hodgkin's disease, hyperthyroidism, amyloidosis, primary biliary cirrhosis, idiopathic pulmonary fibrosis, pulmonary embolism, scleroderma, silicosis, tuberculosis, Gaucher's disease and leprosy. The normal values are 18 to 67 U/ml over 20 years of age (people under 20 have higher levels). (15 Jan 1998) |
| acoustic reference level | The biological reference level for sound measurements. When the term decibel is used to indicate the noise level, a reference quantity is implied; this reference value is usually expressed as a sound pressure of 20 micronewtons per square meter. The reference level is referred to as 0 decibels, the baseline of the scale of noise level's; this baseline is considered the weakest sound that can be heard by a person with very good hearing in an extremely quiet location. Other equivalent reference level's still being used include 0.0002 microbar and 0.0002 dyne per square centimeter. (05 Mar 2000) |
| background level | The average amount of a substance present in the environment. Originally referring to naturally occurring phenomena. Used in toxic substance monitoring. (05 Dec 1998) |
