A safety data sheet ( SDS ), [ 1] material safety data sheet ( MSDS ), or product safety data sheet ( PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products. SDSs are a widely used type of fact sheet used to catalogue information on chemical species including chemical ...
For example, R-22 has one carbon atom, one hydrogen atom (2−1 = 1), two fluorine atoms, and one chlorine atom (4−2−1 = 1), so it is chlorodifluoromethane, while R-134 has two carbon atoms (2−1 = 1), two hydrogen atoms (3−1 = 2), four fluorine atoms, and no chlorine atoms (6−2−4 = 0), so it is one of the tetrafluoroethanes. This ...
Hazard statements are one of the key elements for the labelling of containers under the GHS, along with: [ 3] the identity of the supplier (who might be a manufacturer or importer). Each hazard statement is designated a code, starting with the letter H and followed by three digits. Statements which correspond to related hazards are grouped ...
Process Safety Management of Highly Hazardous Chemicals is a regulation promulgated by the U.S. Occupational Safety and Health Administration (OSHA). [ 1] It defines and regulates a process safety management (PSM) program for plants using, storing, manufacturing, handling or carrying out on-site movement of hazardous materials above defined ...
Water is the chemical substance with chemical formula H 2 O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. [25] Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue color.

Xylitol is a chemical compound with the formula C 5 H 12 O 5, or HO(CH 2)(CHOH) 3 (CH 2)OH; specifically, one particular stereoisomer with that structural formula. It is a colorless or white crystalline solid that is freely soluble in water. It is classified as a polyalcohol and a sugar alcohol, specifically an alditol.
Precautionary statements are one of the key elements for the labelling of containers under the GHS, along with: [ 4] an identification of the product; one or more hazard pictograms ( where necessary) a signal word – either Danger or Warning – where necessary. hazard statements, indicating the nature and degree of the risks posed by the product.
Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH+. 4] [OH−.
