ASTM F1407 - 12(2017) - Standard Test Method for Resistance of Chemical Protective Clothing Materials to Liquid Permeation
Permeation Cup Method This test method establishes a standard procedure for rapidly (in 1 h or less) determining the chemical resistance of specimens of protective clothing materials. This test method can be used to rank materials as to their suitability for use with liquids of known or unknown composition. The breakthrough detection time, permeation rate, or cumulative permeation can be used to identify protective clothing materials that are more likely to limit potential exposures to chemicals. Longer breakthrough detection times and lower cumulative amounts permeated and permeation rates are...
Choosing glove materials and assessing permeation performance
The most common causes of occupational dermatitis, according to the HSE — as reported by dermatologists and occupational physicians under The Health and Occupation Research Network (THOR) — are wet work (25% of total), soaps and cleaners (24%), rubber chemicals and materials (16%). Comfort and usability increase the likelihood of people wearing protection; manufacturers are always improving the anatomical design of their gloves. They are also working on levels of grip, for example by developing different surface finishes on the exterior of some gloves, such as dip rough, textured palm...

NIOSH Skin Permeation Calculator Updated
Through partnership with the University of Cincinnati, the NIOSH Skin Permeation Calculator has been updated with enhanced features and a new user interface. The improved calculator allows for simulation of typical occupational exposure scenarios. The calculator estimates fluxes, skin concentrations, and amounts absorbed from any size dose applied to partially or fully hydrated skin. The calculator is available on the NIOSH Web site at Source : http://www.cdc.gov/niosh/topics/skin/finiteSkinPermCalc.html
Vulnerability of oil contaminated fire retardant overalls
Overalls become oil-contaminated very rapidly in many work situations, particularly offshore, in some cases within one day. From time to time, there are significant hydrocarbon fires offshore. There is evidence that frequent washing reduces the fire retardant properties of some materials, thereby increasing personal risk to persons and compromising their safety in a fire. Secondly, there is a problem with fires in the laundries offshore. Because of the large potential for escalation of fires offshore, the reduction of fuel loading and the prevention of ignition sources must remain a high priority...
New Standard for Chemical Permeation Testing Approved by ASTM Personal Protective Clothing Committee
Chemical protective clothing has been widely used to protect skin from health hazards that can be found in the workplace or during a terrorist attack. A new ASTM International standard provides directions in using a computer program, called a permeation calculator, to analyze data following a permeation test, in order to determine when chemicals have gotten inside the clothing. The new standard, ASTM F2815, Practice for Chemical Permeation Through Protective Clothing Materials: Testing Data Analysis by Use of a Computer Program, was developed by Subcommittee F23.30 on Chemicals, part of ASTM International...
Expositions aux cancérogènes : les vêtements de protection inefficaces
Une note du ministère du Travail, dont Santé & Travail a pris connaissance, indique que les vêtements de protection contre les projections de liquides et les pulvérisations sont inefficaces. Une campagne de tests pratiqués sur une dizaine de modèles montre leur non-étanchéité. http://www.sante-et-travail.fr/expositions-aux-cancerogenes---les-vetements-de-protection-inefficaces_fr_art_641_43436.html
