Because of their strong growth of use on an industrial scale, the development of nanoparticles, their preparation and their integration into different products involve a significant occupational exposure potential, millions of workers across the world. However, many studies have shown adverse effects on skin (irritation, dermatitis). Several organizations recommend caution by wearing "type 5" chemical protective clothing to prevent any risk. However, while some studies have been conducted to assess their performance against exposure to nanoparticles, they have not been conducted under conditions of an actual exposure in the workplace. This project was carried out to assist in the evaluation of the effectiveness of protective clothing against the nano and submicron aerosol in conditions of actual exposure. 5 protective clothing were investigated: 4 type 5 coveralls and 1 lab coat as a reference. In a first step, the deformation of the clothing during use was measured. Thereafter mechanical deformations, simulating the real condition in use of materials, were applied simultaneously with exposure to particles. It turns out that for most materials the penetration rate is relatively low. It has been shown that mechanical stress, in our selected conditions, had no significant impact on the effectiveness of protective clothing tested.
