Operational Hazard Zone

What is OHZ?

An Operational Hazard Zone (OHZ) is a designated geographical area where military exercises, testing of ordnance, or hazardous materials handling takes place, posing risks to personnel and civilians. In India, these zones are established by the Ministry of Defence and the Indian Armed Forces to control access during live-fire drills, explosive ordnance disposal, or chemical warfare training. OHZs are marked on military maps and communicated to local authorities to ensure public safety, especially near cantonments and firing ranges. The concept is also used in disaster management for temporary danger areas during natural calamities or industrial accidents. These zones require strict adherence to safety protocols, including restricted entry, warning systems, and evacuation plans. For competitive exams like those for the National Defence Academy (NDA) or Combined Defence Services (CDS), understanding OHZ is relevant for questions on military operations and safety procedures. The demarcation of OHZs helps balance operational readiness with civilian protection, reducing accidental casualties and maintaining security around sensitive defence installations.
