Protective clothing applications

Protective clothing must be worn whenever the wearer faces potential hazards arising from chemical exposure. Some examples include 

Within each application, there are several operations that require chemical protective clothing. For example, in emergency response, the following activities dictate chemical protective clothing use

Electrospun nanoiiber mats by modified electospinning system have high porosity. Results show that the porosity of nanofiber mats increases by decreasing speed rotation of dmm. Air permeability and moisture transfer of nanofiber mats were reduced with reduction the porosity of nanofiber mats. Based on experimental results, moisture transfer behavior is influenced by nanofiber mats porosity. Bulk nanofiber mats with high rates of water vapor diffusion and low air permeability are promising candidates for protective clothing applications. 

Bulky nanofibre mats with high rates of water vaponr diffusion and low air permeability are promising candidates for protective clothing applications.

PPS fiber has excellent chemical resistance. Only strong oxidising agents cause degradation. As expected from inherent resia properties, PPS fiber is flame-resistant and has an autoignition temperature of 590°C as determined ia tests at the Textile Research Institute. PPS fiber is an excellent electrical iasulator it finds application ia hostile environments such as filter bags for filtration of flue gas from coal-fired furnaces, filter media for gas and liquid filtration, electrolysis membranes, protective clothing, and composites.

Because of its excellent range of properties and reliability, poly(fluoroalkoxyphosphazene) elastomers are used as seals, gaskets, and shock mounts in demanding military, aerospace, petroleum and industrial applications. In addition, applications under development for this elastomer include fuel hoses for artlc use, coated fabrics for protective clothing, sealants, coatings and medical devices. 

In this part of the study, the internal dose of propoxur was assessed for HV applicators (n = 9) and harvesters (n = 18) using biological monitoring in two trials. In the first trial, workers wore their normal work clothing, followed by a trial where the same workers wore additional protective clothing. The minimum period between the two trials was 5 days. 

During application, temperatures ranged from 17 to 27°C and from 16 to 28°C for the work clothing and protective clothing trials, respectively. During harvesting, temperature ranges were 19 to 26°C and 15 to 25°C for both exposure scenarios. 

Concentrations of propoxur in the breathing zone ranged from 0.6 to 25 (median, 0.7) pg/m3, and from 0.4 to 29.4 (median, 1.2) pg/m3 for applicators in exposure scenarios without and with protective clothing, respectively. For... 

When normal work clothing was worn, IPP excretion ranged from 128 to 1505 nmol and from 83 to 2189 nmol for applicators and harvesters, respectively. The amount of IPP excreted after working with protective clothing was significantly reduced to 70 to 926 nmol and 16 to 917 nmol for applicators and harvesters, respectively (Table 4). 

No significant relationship between the IPP excreted and hand exposure was observed for the applicators wearing normal work clothing or for protective clothing (p = 0.09 and p = 0.73, respectively). Skin moisture variables did not contribute significantly to the explained variation.

The design of a study by Davies et al. (1982) for mixers and applicators was similar to that of Nigg and Stamper (1983). "Between-days" variances of exposure were not given. Mean urinary metabolite concentrations were used to show reduction of internal exposure by protective clothing. The design of the study by van Rooij et al. (1993) was similar to our study (i.e., "within-worker" comparisons of internal exposure). Because no potential dermal exposure was assessed in this study, "within-worker" variances of potential exposure are not known.
