Performance attributes relevant to thermal wear comfort of hip protective garment: influence of comprising pad materials, pad thickness, pad area, and pocket fabric structure

PurposeThis study aimed to evaluate the performance attributes relevant to thermal wear comfort of the commercially available hip protective pads and materials intended for impact protection that can be used for the hip protective pad.Design/methodology/approachThe performance attributes relevant to thermal wear comfort (i.e. dry thermal resistance and evaporative resistance) of the pads were tested using MTNW Integrated Sweating Guarded Hotplate (iSGHP).FindingsIt was found that: the pad with more porous structure has more advantages in terms of evaporative resistance; the permeability index will be higher on the pad with an opening such as a segmented pad; the permeability index will be lower on the thicker and larger pad. The pocket fabric with open structure will have lower dry thermal resistance and evaporative resistance.Originality/valueThe study results showed that the properties of the utilised materials influenced thermal comfort performance. These results could be useful for designing and engineering hip protective garments.

Study of the Change of the Specialists' Isolative Garment Properties Against the Effects of Peroxide Decontamination Mixture

The influence of the peroxide decontamination mixture on the barrier polymeric material used for the construction of the anti-gas protective garment OPCH-05 has been study. This kind of mixture is used with the help of the decontamination vehicle ACHR-90 and its EDS mixture. The both soldiers and operators of the ACHR-90 or the EDS mixture can be in a direct contact with spattering decontamination mixture that can cause significant damages of the anti-gas protective garment OPCH-05. For evaluation of protective properties and their potential changes the MIKROTEST method and methodology has been used. This paper is another publication which deals with the influences of decontamination mixtures introduced in the Czech Armed Forces Chemical Corps armament on the barrier material composed of the butyl-rubber polymeric mixture in combination with the polyamide textile.

An Investigation to Determine an Optimum Protective Garment Material in Nuclear Medicine

Aim: The aim of this study is to find an optimum material to protect garment for protection against 99Tcm radionuclide.Materials and Methods: Monte Carlo simulation code was applied to investigate radiation attenuation of 13 shielding materials including: Ba, gray Sn, white Sn, Sb, Bi, Bi2O3, BaSO4, Sn/W, Sb/W, Pb and W with thicknesses of 0.5 and 1 mm to determine an optimum protective garment material in nuclear medicine against 99Tcm. Furthermore, the dose enhancement on the staff body was investigated for shielding materials such as tungsten and lead.Results: The findings of the simulations show that the maximum and minimum attenuation obtained with thicknesses of 1 mm W and 1 mm BaSO4 were 96.46% and 14.2%, respectively. The results also demonstrate that tungsten does not cause any dose enhancement on staff body but this is not true for lead. Tungsten provides the highest radiation attenuation without dose enhancement on the body of staff.Conclusion: Among materials evaluated, tungsten is the optimum material and it can be applied for the design of protective garment for nuclear medicine staff against 99Tcm.
