Bogerd, C.P. (author), Langenberg, J.P. (author), den Hartog, E.A. (author)Armed forces typically have personal protective clothing (PPC) in place to offer protection against chemical, biological, radiological and nuclear (CBRN) agents. The regular soldier is equipped with permeable CBRN-PPC. However, depending on the operational task, these PPCs pose too much thermal strain to the wearer, which results in a higher...article 2018

den Hartog, E.A. (author), Rubenstein, C.D. (author), Deaton, A.S. (author), Bogerd, C.P. (author)A major concern for responders to hazardous materials (HazMat) incidents is the heat strain that is caused by fully encapsulated impermeable (NFPA 1991) suits. In a research project, funded by the US Department of Defense, the thermal strain experienced when wearing these suits was studied. Forty human subjects between the ages of 25 and 50...article 2017

den Hartog, E.A. (author), Koerhuis, C.L. (author)The focus of this study was to establish a relationship between physical discomfort and performance. Eleven healthy male subjects participated in this pilot study. The subjects performed a 2-h protocol without and with significant thermal and mechanical discomfort. Various cognitive tasks were executed repeatedly during the protocol to evaluate...article 2016

Ambesi, D. (author), Kleijn, C.R. (author), den Hartog, E.A. (author), Bouma, R.H.B. (author), Brasser, P. (author)In chemical, biological, radiological, and nuclear protective clothing, a layer of activated carbon material in between two textile layers provides protection against hazardous gases. A cylinder in cross flow, sheathed by such material, is generally used to experimentally test the garment properties. This is, however, complicated and predictive...article 2014

(author)Calculation of evaporative heat loss is essential to heat balance calculations. Despite recognition that the value for latent heat of evaporation, used in these calculations, may not always reflect the real cooling benefit to the body, only limited quantitative data on this is available, which has found little use in recent literature. In this...article 2013

Havenith, G. (author), den Hartog, E.A. (author), Martini, S. (author)Heat strain in chemical protective clothing is an important factor in industrial and military practice. Various improvements to the clothing to alleviate strain while maintaining protection have been attempted. More recently, selectively permeable membranes have been introduced to improve protection, but questions are raised regarding their...article 2011

Houwelingen, T. (author), Kistemaker, L.A. (author), de Kant, S. (author), den Hartog, E.A. (author), TNO Defensie en Veiligheid (author)The past decades show an increasing variety in the design and application of personal protective equipment, PPE. Even within the PPE aimed at CBRN protection the future user can choose from a bewildering amount of producers and models. To make his predicament even worse he also has to deal with a fairly wide field of potential hazards and...conference paper 2010

De kleding en uitrusting kan worden ingezet om hulpverleners beter te beschermen en de werkzaamheden onder risicovolle omstandigheden toch uit te kunnen voeren. Echter, in sommige gevallen...report 2010
