All RELs are located in the NIOSH Pocket Guide to Chemical Hazards, along with other key data for 677 chemical or substance groupings. The Pocket Guide is a source of general industrial hygiene information for workers, employers, and occupational health professionals. NIOSH recommendations are also published in a variety of documents, including:
NIOSH was created by the Occupational Safety and Health Act of 1970 and began operating in May 1971. It was originally part of the Health Services and Mental Health Administration, and was transferred into what was then called the Center for Disease Control (CDC) in 1973. NIOSH's initial headquarters were located in Rockville, Maryland.
A TB guide, published by NIOSH in 1999, describes 13 combinations of contaminants with unique color markings. The definitive guide from ANSI, who, since the passage of 42 CFR 84 in 1995, has published a 2001 revision of K13.1-1973, named Z88.7-2001, describes 14 combinations of contaminants with unique color markings, based on 13 out of the 28 ...
Methyl cyanoacrylate ( MCA; also sometimes referred to as α-cyanoacrylate or alpha-cyanoacrylate) [3] is an organic compound that contains several functional groups: a methyl ester, a nitrile, and an alkene. It is a colorless liquid with low viscosity. Its chief use is as the main component of cyanoacrylate glues.
Structure and basic properties. Phosgene is a planar molecule as predicted by VSEPR theory. The C=O distance is 1.18 Å, the C−Cl distance is 1.74 Å and the Cl−C−Cl angle is 111.8°. [9] Phosgene is a carbon oxohalide and it can be considered one of the simplest acyl chlorides, being formally derived from carbonic acid .
Propionitrile, also known as ethyl cyanide and propanenitrile, is an organic compound with the formula CH 3 CH 2 CN. It is a simple aliphatic nitrile. The compound is a colourless, water-soluble liquid. It is used as a solvent and a precursor to other organic compounds.
2-Pentanone or methyl propyl ketone ( MPK) is a ketone and solvent of minor importance. It is comparable to methyl ethyl ketone, but has a lower solvency and is more expensive. [5] It occurs naturally in Nicotiana tabacum (Tobacco) [6] and blue cheese as a metabolic product of Penicillium mold growth. [7]
Y N. ?) Infobox references. 2-Ethoxyethanol, also known by the trademark Ethyl cellosolve, is a solvent used widely in commercial and industrial applications. It is a clear, colorless, nearly odorless liquid that is miscible with water, ethanol, diethyl ether, acetone, and ethyl acetate. [3] 2-Ethoxyethanol is manufactured by the reaction of ...
