All Steel Blue boots are Anti-Static, unless they contain an ‘EH Series’ label, which stands for ‘Electrical Hazard’.
Another way you can tell if your work boots are Anti-Static is by looking for an A, O1, O2, O3, S1, S2 or S3 symbol on the license label inside the boot.
The Electrical Resistant properties have been developed to stay in place throughout the life of the work boots. However, it’s important to continually check the resistance as it can deteriorate with sole wear, water or metal contamination which can lower the Electrical Resistance, taking it outside of the required range and allowing charges to more easily pass through the soling.
