The biocidal textile support includes bronopol in the dry state present on the surface of the support and having a contact biocidal action, the bronopol being linked to the support by a photo-crosslinkable or photo-polymerizable binder, and its use as an element of a device for protecting against biological risks. A biocidal suit or garment and a mask, preferably antibacterial or antiviral, including such a biocidal support, are also described.
