CIS 94-2034 Exposure limits for substances and products [Denmark]
Grænseværdier for stoffer og materialer [in Danish]
This guidance note replaces the one published Jan. 1992 (see CIS 92-724). It reviews the regulatory background, describes how exposure limits (8h-TWA) are established and explains the different sections of the exposure limit tables. The following tables are provided: exposure limits (in ppm and/or mg/m3) for ca. 1100 atmospheric contaminants (gases, vapours and particulate matter suspended in air), with corresponding Chemical Abstracts Service Registry Numbers; existing or tentative exposure limits (in ppm) for ca. 400 organic solvents; exposure limits (in fibres/cm3 or mg/m3) for 36 kinds of dust; calculation methods for exposure limits when several hazardous substances are present; list of five welding-related exposure limits; lists of substances, processes and other factors considered carcinogenic (with reference to relevant documentation); highlights of exposure limit changes since the previous edition of the guidance note; list of expected changes of exposure limits.

CIS 94-2008 Pentafluoroethane (HFC 125)
Pentafluoroethane is a non-flammable colourless gas that is currently under development as an alternative to chlorofluorocarbons and is not yet available commercially. Its toxicity is very low (the 4h LC50 in rats is greater than 3,928,000 mg/m3 = 800,000ppm). Cardiac sensitization in dogs is observed above 100,000ppm. No mutagenicity or developmental toxicity has been seen in laboratory experiments. No effects on human beings have been reported. An occupational exposure limit (8h time-weighted average) of 1000ppm is recommended by producers.

Occupational exposure limits 1994
This Guidance Note is revised and reprinted annually; this edition replaces Guidance Note EH 40/93. It gives details of the occupational exposure standards (OESs) (8h TWA and 15min STEL, in ppm and/or mg/m3, as appropriate) which should be used for the purposes of determining the adequacy of the control of exposure by inhalation to substances hazardous to health. These limits form part of the requirements of the COSHH Regulations 1988 (see CIS 89-1092). Contents: legal background; setting and application of OESs; mixed exposures; exposure monitoring; list of maximum exposure limits for 38 substances; list of approved occupational exposure standards for approx. 500 substances; proposed changes for 1995 to the list of approved OESs (16 substances); proposed changes to the reference temperature and pressure in setting OESs; list of 11 substances and substance groups for which new or revised maximum exposure limits will come into force during the summer of 1994 with COSHH 1994; list of 51 substances and substance groups to be reviewed by ACTS/WATCH until 1994. In appendices: calculation of exposure with regard to the specified reference periods; methods of measurement of fibre concentrations of MMMFs; special comments on cotton dust, asphyxiants, lead, rubber fume and dust, grain dust, asbestos, carcinogens (with lists).

A critique of recommended limits of exposure to ultraviolet radiation with particular reference to skin cancer
This report reviews biological experimental data on the effects of exposure to ultraviolet radiation and compares them with current international and foreign (non-British) national recommendations. Compliance with the current recommendations appears to be sufficient to protect most Caucasians against acute skin effects. However, the data are less conclusive when considering protection of the eyes. Epidemiological data suggest that 40 years of occupational exposure of the skin at the limit recommended by the International Non-Ionising Radiation Committee (INIRC) may increase the normally low risk of developing non-melanoma skin cancer by a factor of 3.

Review of occupational exposure to optical radiation and electric and magnetic fields with regard to the proposed CEC physical agents directive
Part 1 of this review considers occupational exposure to optical radiation, ultra-violet radiation, lasers and infrared radiation. It is concluded that if suitable control measures are enforced, there should be very few cases where optical radiation emissions from artificial sources exceed the ceiling levels in the proposed CEC Directive; areas where overexposure may occur are highlighted. Part 2 covers occupational exposure to electric and magnetic fields, static fields, extremely low frequency fields, broadcast and telecommunications, radar and navigation, heating, visual display units and other sources and identifies a number of areas where the action and hazardous activity levels proposed by CEC may be exceeded.

Lowering threshold limit values (TLVs) has additional benefits
Early attempts to develop limits on the levels of volatile industrial substances to which workers could be exposed are described along with events leading to the formation of the American Conference of Government Industrial Hygienists (ACGIH) and its Airborne Contaminants Committee, later to be the Threshold Limit Value (TLV) Committee. Currently, the TLV Chemical Substances Committee has four subcommittees reviewing data for different types of industrial substances. As the TLVs are lowered to prevent evidence of toxicity in exposed workers, the possibilities for fire/explosion due to reaching flammable limits are also decreased.

Protection of workers from power frequency electric and magnetic fields - A practical guide
This ILO publication comprises a review of data on the effects of extremely low frequency (ELF) electric and magnetic fields on biological systems pertinent to the evaluation of health risks for workers. It provides information on the possible effects of exposure to 50/60Hz electric and magnetic fields on human health and gives guidance on the assessment of risks from occupational exposure. Areas in which uncertainties exist and further research is needed are also indicated. Biological effects of ELF electric and magnetic fields and national exposure standards are presented in appendices. Glossary.
