This is achieved using clothing designed to provide protection against the influence of bad weather conditions and excessive wind and cold. When using this type of clothing, the instructions for use should be read as well as paying attention to the marking, which indicates the water penetration resistance and steam resistance.
The water penetration resistance refers to the hydrostatic pressure supported by a material, as a measure of the opposition to water passing through it.
The steam resistance is the property of a fabric that defines the amount of “latent” evaporation heat flow within a given temperature range.
As a function of these parameters, this type of clothing may be category I, II or III, depending on the test data obtained by the manufacturer.
When working with aggressive chemical products (acids and bases), the clothing to use must be suitable for protecting the user in the case of Contact with these chemical products.
