Heat and mechanical protection properties of 6 fabric combinations commonly used in firefighters' protective clothing were assessed before and after different heat treatment. It was shown that after heat exposure, the values obtained were generally lower than in the original state. The mechanical properties of the materials were more affected by heat than by heat protective properties. In 2 cas...

Anti-vibration gloves have been used in real workplaces to reduce vibration transmitted through hand-held power tools to the hand. Generally materials used for vibration attenuation in gloves are resilient materials composed of certain synthetic and/or composite polymers. The mechanical characteristics of the resilient materials used in anti-vibration gloves are prone to be influenced by enviro...

The purpose of protective clothing and other personal protective equipment (PPE) is to provide escape time, to reduce the burn injury level, and to prevent aggravation of the consequences to workers during exposure to an electric arc. In this study the flammability properties of 12 different types of flame-retardant fabrics were compared with the normally used flame spread test method (EN 532:1...

A collaborative approach, involving resources and expertise from several countries, was used to develop a test cell to measure cumulative permeation by a solid-state collection technique. The new technique was developed to measure the permeation of pesticide active ingredients and other chemicals with low vapor pressure that would otherwise be difficult to test via standard techniques. The deve...

OBJECTIVE To assess maternal and child risk compensation behaviors in response to several commonly used safety measures. METHODS We administered a previously validated self-report measure of risk tolerance to a total of 151 mothers and their children in grades 3-7. Mothers indicated the level of risk they would permit their child to assume; children were questioned regarding the degree of phy...
