High-visibility weather protective clothing (high-visibility with rain protection)

High-visibility weather protective clothing is warning clothing with rain protection. It meets the high-visibility standard DIN EN ISO 20471:2017-03 and, at the same time, the standard for rain protective clothing, formerly EN 343 and now EN ISO 24232. The garment therefore carries two markings, each with its own class: the high-visibility class 1 to 3 and the weather protection classes for water resistance (Wp) and breathability (Ret).

When is this relevant?

Relevant for work outdoors where visibility and wet protection come together, for example in road construction, logistics or maintenance work in traffic areas. Under DGUV Information 212-016, warning clothing for outdoor work often has to protect against moisture, wind and cold as well. Which classes are needed follows from the risk assessment.

Two class systems, do not confuse them

The high-visibility class (1, 2 or 3) depends on the minimum area of fluorescent and retroreflective material and applies to visibility. The weather protection classes (each 1 to 4) rate water resistance and breathability. The DGUV expressly points out that these classes must not be confused with the classes of warning clothing.
