Practical guides to explosion protection, written for the people who have to specify, install and certify equipment in classified areas.
Every guide below comes out of real projects: reading area classification drawings, matching a marking to a zone, and getting equipment through acceptance without a rejection at the gate. Where a standard matters we cite the clause so you can check it yourself. If your case is not covered, send us the details — zone, gas or dust group, and what you are replacing.
Ex FundamentalsHow to Read an Ex Marking: Ex d IIB T4 Gb DecodedRead any Ex nameplate left to right: protection concept, gas group, temperature class, equipment protection level — and the ambient range that quietly limits where it may be installed.Read the guide ›
Ex FundamentalsEx d vs Ex e vs Ex i: Which Protection Type Do You Need?Flameproof, increased safety and intrinsic safety are three different answers to the same question. One fact about the device decides which one applies.Read the guide ›
Ex FundamentalsHazardous Area Classification: Zones, Groups and T-ClassesZone, gas group and temperature class are derived — not chosen. Here is how the three blocks are set, and the six lines a supplier needs to quote compliant equipment.Read the guide ›
Selection & ComplianceATEX vs IECEx vs Class/Division: Which Do You Need?ATEX, IECEx and the North American Class/Division system describe the same physics but are not interchangeable paperwork. The installation country decides.Read the guide ›
Selection & ComplianceHow to Verify an Explosion-Proof CertificateA ten-minute routine that prevents most disputes: match the model, read the conditions of use, and confirm the certificate in the public register.Read the guide ›
Selection & ComplianceHow to Choose Explosion-Proof Lighting for Zone 1Marking first, light level second. How to size luminaires by lux target instead of old wattage, match the beam to the mounting height, and specify for corrosion.Read the guide ›
Ex FundamentalsIP65 vs IP66 vs IP67: What IP Ratings Mean on Ex EquipmentTwo independent claims on one nameplate — and only one of them is explosion protection. What each digit means and which rating survives your environment.Read the guide ›
Selection & ComplianceExplosion-Proof LED vs Fluorescent Lighting: Which to SpecifyCompared where it actually matters for a classified area: maintenance access, temperature class and the mechanics of a compliant retrofit.Read the guide ›
Selection & ComplianceExplosion-Proof Lighting Maintenance and Inspection: IEC 60079-17 GuideThe three inspection grades, how often to inspect, and the faults that cause most non-conformities in real installations.Read the guide ›
