Proceedings of the International Occupational Hand-Arm Vibration Conference
(In English, French.) The Organization, Geneva, Switzerland, International Standard ISO 2631-1978(E). Jan 1978, 15 pp. Abstr in: CIS Abstracts (CIS 78-1278). This international standard defines and gives numerical values for limits of exposure for vibrations transmitted from solid surfaces to the human body, in the frequency range 1 to 80 Hz. It may be apphed, within the specified lrequency range, to periodic vibrations and to random or nonperiodic vibrations with a distributed frequency spectrum. Provisionally, it may also be applied to continuous shock-type excitation in so far as the energy in question is contained within the 1 to 80 Hz band. An introduction is followed by sections devoted to: charactefisation of vibration exposure (direction of vibration, location of measurement, intensity of vibration, measuring equipment, random or broad-band vibration analysis, exposure time); vibration evaluation guide (fatigue, decreased proficiency boundary, reduced comfort boundary, health or safety exposure limit, evaluation of frequency spectrum, vibration in more than one direction simultaneously). Numerous tables and graphs.

A personal dry-ice cooling jacket developed to increase available productive time in industrial heat stress environments was evaluated in two industrial and two laboratory environments. A p r o t o t y p e design tested in a tyre manufacturing plant and a chemical manufacturing plant on six workers was successful in significantly reducing sweat loss by 30% and in providing cooling for over three hours while permitting the required task mobility. The laboratory evaluations were performed in drybulb temperatures of 35 and 45°C at 33 mm Hg water vapour pressure with two clothed men pedalling for 60 min. Mean heart rate throughout the 60 min exposure was 14 beats/rain less with
