The article presents the Time4Mask application developed at the Central Institute for Labour Protection – National Research Institute (CIOP-PIB) for selecting and monitoring the duration of use of respiratory protective equipment against bioaerosol in selected work environments (animal husbandry, sewage treatment plants, waste sorting plants). The basic functionalities of the application were described in a synthetic manner, along with the presentation of the possibilities of visualizing the training content. In particular, the operation of the application in the mobile version was presented using the "step by step" method. The Time4Mask application has been implemented in the mobile version for iOS and Android by placing a free application on the CIOP-PIB account and in the Apple App Store and Google Play stores.

The selection of thermal-insulating clothing for employees performing activities with different energy expenditures or exposure to significant temperature changes during work is a relevant problem. To reduce the heat load of employees and improve the ergonomics of clothing, a model of the innovative thermal-insulating jacket with the addition of highly insulating, lightweight aerogel and PCM was developed in Central Institute for Labour Protection – National Research Institute. The developed clothing was evaluated in terms of thermal insulation and cooling efficiency based on the results of tests of the heat flux density from the thermal manikin. The obtained increase in the heat flux density value in the areas with PCM immediately after putting on the jacket shows the cooling effect of the manikin. However, this effect lasts only for about 5-10 minutes. The results of thermal insulation measurements indicate that the aerogel is most effective in the areas of the jacket where it is present alone (without PCM).
