Dermal exposure to dry powder spray paints using PXRF and the method of Dirichlet tesselations.

This paper describes workplace dermal exposure measurements that were carried out by the Health and Safety Laboratory as part of the EU RISKOFDERM project to measure dust contamination. Exposure to dry powder spray paints was measured at five sites on 12 subjects. Twenty-two samples were obtained, of which eight contained triglycidyl isocyanurate (TGIC) and 14 did not.

Dermal exposure to electroplating fluids and metalworking fluids in the UK.

This paper describes workplace dermal exposure measurements that were carried out by the Health and Safety Laboratory as part of the EU RISKOFDERM project. Exposure to metalworking fluids (MWFs) was measured at three sites on 25 subjects who were 'mechanically treating solid objects' as they loaded and supervised milling and boring machines and lathes. Thirty-one samples were obtained, of which 18 were exposures to neat mineral oils and 13 to water-oil mixes.

The health and safety executive interlaboratory quality control scheme for isocyanates.

The inclusion of isocyanate analysis within the AQUA (Analytical Quality Assurance) interlaboratory quality assurance scheme was established in 1984. (The AQUA interlaboratory quality assurance scheme is equivalent to external quality assessment, in North America the term proficiency testing is preferred.) The participants include university, industrial, occupational consultant and government laboratories, both in the U.

Evaluation of total isocyanate-in-air method using 1-(2-methoxyphenyl)piperazine and HPLC.

The United Kingdom Health and Safety Commission has set a 'common control limit' for workplace exposure to all isocyanates. This limit replaces the previous United Kingdom threshold limit values, which were set for just four species of monomeric isocyanate compounds. This new control limit is set at 20 micrograms of isocyanate group per cubic meter of air expressed as an eight-hour weighted average, and 70 micrograms of isocyanate group per cubic meter of air as a 10-minute weighted average.
