Safety Data Sheets

Tfx Toxic effect(s). Tinnitis A ringing, roaring, or hissing sound in one or both ears. TLV Threshold Limit Value is a term used by ACGIH to express the airborne concentration of material to which nearly all persons can be exposed day after day without adverse effects. ACGIH expresses TLVs in three ways: ●● TLV-TWA: The allowable time-weighted average concentration for a normal 8-hour workday or 40-hour workweek. ●● TLV-STEL: The Short-Term Exposure Limit, or maximum concentration for a continuous 15-minute exposure period (maximum of four such periods per day, with at least 60 minutes between exposure periods, and provided the daily TLV-TWA is not exceeded). ●● TLV-C: The ceiling exposure limit; the concentration that should not be exceeded even instantaneously. TOC Tag Open Cup. See “Flashpoint.” Torr A unit of pressure, equal to 1/760 atmosphere. Toxemia Poisoning by way of the bloodstream. Toxic A chemical falling within any of the following categories: ●● A chemical that has a median lethal dose (LD 50 ) of more than 50 milligrams per kilogram but not more than 300 milligrams per kilogram of body weight when administered orally as a single dose to laboratory animals. ●● A chemical that has a median lethal dose (LD 50 ) of more than 200 milligrams per kilogram but not more than 1,000 milligrams per kilogram of body weight when administered by continuous contact with the bare skin of laboratory animals as a single dose or multiple doses given within 24 hours. ●● A chemical that has a median lethal concentration (LC 50 ) in air of more than 500 parts per million but not more than 2,500 parts per million by volume of gas or more than two milligrams per liter but not more than 10 milligrams per liter of vapor, or more than 0.5 milligrams per liter but not more than 1.0 milligrams per liter of mist, fume or dust. The LC50 values are based on 4 hour tests in laboratory animals. Toxic Substance Any substance that can cause acute or chronic injury to the human body, or which is suspected of being able to cause diseases or injury under some conditions. Toxicity The sum of adverse effects resulting from exposure to a material, generally, by the mouth, skin or respiratory tract. Toxicology Scientific study of poisons, their actions, their detection, and the treatment of conditions produced by them. Tracheitis Inflammation of the trachea.
