Thermal Hazards - Cold EN511 THERMAL HAZARDS – COLD e. g.: 2 3 1 RESISTANCE TO RANK (1 = lowest; 0 = failed) CONVECTIVE COLD 1 — 4 CONTACT COLD 1 — 4 PERMEABILITY TO WATER 0 — 1 4.0 Static Electricity Everybody produces electricity which, unless it is allowed to “earth”, can build up and discharge in the form of a static “spark”. This static electricity must be conducted safely away from the body before the build up becomes critical in high risk areas. Gloves containing a conductive element safely discharge electrostatic build up, effective in highly flammable atmospheres and in many “clean” situations, are approved to EN 420.
