Hoping for the best, planning for the worst

By Larry Scott 

Chemicals are woven into every part of modern life — from the fuels that power our vehicles to the plastics, fabrics, and fertilizers we depend on daily. 

When these substances escape their intended containment, they become hazardous materials, or HAZMAT, capable of causing fires, toxic vapors, chemical burns, or environmental harm. 

Fortunately, major releases are rare thanks to rigorous equipment standards and operating procedures. In Cochise County, preparedness rests with the Local Emergency Planning Committee (LEPC), a community-based group created under the federal Emergency Planning and Community Right-to-Know Act (EPCRA) of 1986. 

Daniel S. Duchon, Director of Emergency Management, leads the team in developing response plans, managing chemical inventories, and strengthening public safety. 

The LEPC maintains an up-to-date Hazardous Materials Response Plan focused on facilities storing chemicals above reportable quantities. In this region, that typically includes vehicle fuels at gas stations, propane, pool chlorine, agricultural fertilizers (especially around Willcox), and chemicals used in mining operations such as those at Apache Nitrogen Products. 

A critical component is the detailed inventory of chemical identities, quantities, storage locations, contact information, and access procedures. The plan also addresses materials transported through the county via Interstate 10 and rail lines. HAZMAT placards on vehicles and containers provide immediate identification numbers that link to national databases, guiding responders on hazards and safe handling. 

Response efforts emphasize building local capability. The LEPC assesses resources, integrates HAZMAT planning into broader emergency management, conducts regular training exercises, and fosters relationships with mutual aid partners and contractors. Responders — primarily firefighters with specialized HAZMAT training — practice using the Incident Command System (ICS), a standardized framework that enables independent agencies to work together seamlessly. ICS has proven so effective it is now used for other emergencies, including wildland fires.
