The health authorities have determined that the threshold limit values
for electromagnetic fields around transmitters in mobile phones and other equipment should be the same as those recommended by the International Commission on Non-ionising Radiation Protection (ICNIRP).
Documentation of the threshold limit values
and biological exposure indices: Vol.
For many, this effort includes considerable work to meet MSHA threshold limit values
or exposure limits, and minimize miner exposure to certain substances.
The elements or oxides listed in table 1 correspond to the ACGIH categories located in [TLV Threshold Limit Values
for Chemical Substances and physical Agents in the Workroom Environment].
The Indoor Advantage Gold program uses, as a basis, the Chronic Reference Exposure Levers set by the California Office of Environmental Health Hazard Assessment, as opposed to threshold levels determined through total volatile organic compounds (VOCs) and threshold limit values
Occupational Safety and Health Administration's (OSHA) permissible exposure levels, the American Conference of Governmental Industrial Hygienists' (ACGIH) Threshold Limit Values
(TLVs), German Research Society's (MAK) values, National Institute for Occupational Safety and Health (NIOSH) recommended exposure levels, and U.
The magic bullet, a drop-in replacement solvent that provides high threshold limit values
(TLVs) and the good cleaning characteristics of 1,1,1 trichloroethane and CFC 113 without any ozone depletion potential, does not, at present, exist.
Small amounts of phenol and ammonia are emitted, but at emission levels generally well below currently established threshold limit values
Although the mean values of most of the chemical parameters monitored during the reference period were typically lower than the standard World Health Organization-prescribed threshold limit values
, the mean values of metals like Fe (iron), Mn (manganese), and Al (aluminum) slightly exceeded their prescribed threshold limit values
It forced the inclusion of a cancer warning label on Material Safety Data Sheets and led the American Conference of Governmental Industrial Hygienists to propose in its 1995-96 Threshold Limit Values
pamphlet that hardwood dust be given a rating of A1 for carcinogenicity.
Threshold limit values
in air (MAK values) as well as for body fluids (BAT values) are given wherever tolerable concentrations can be defined.
This book contains a list of scientifically recommended threshold limit values
for about 900 chemical compounds.
