The chemical security mission is to safeguard the American people by preventing the misuse of chemicals in a terrorist attack on the homeland.
Securing our nation’s chemical sector infrastructure is crucial to our economic prosperity, national security, and public health and safety. Every day, thousands of chemical facilities across the country—from small companies to national laboratories—use, manufacture, store, and transport dangerous chemicals in a complex, global chain that affects other critical infrastructure sectors.
Enhancing security and resilience across the chemical industry to reduce the risk of dangerous chemicals being weaponized requires a collaborative effort. To this end, the Cybersecurity and Infrastructure Security Agency (CISA) has developed voluntary and regulatory programs and resources to help stakeholders—private industry, public sector, and law enforcement—secure chemical facilities from many threats: cyberattacks, biohazards, insider threats, and theft and diversion for use in chemical or explosive weapons.
Chemical Facility Anti-Terrorism Facility Standards (CFATS)
The nation's first regulatory program focused on security at high-risk chemical facilities. CFATS identifies and regulates high-risk facilities to ensure security measures are in place to reduce the risk that dangerous chemicals are weaponized.
CISA’s ChemLock program is a completely voluntary program that provides facilities that possess dangerous chemicals no-cost services and tools to help them better understand the risks they face and improve their chemical security posture in a way tha
Ammonium Nitrate Security Program (ANSP)
The ANSP is a proposed regulatory program that seeks to reduce the likelihood of a terrorist attack involving the misuse of ammonium nitrate by creating a registration program for purchasers and sellers.
CISA in collaboration with the Chemical Sector Coordinating Council (SCC) hosts the annual Chemical Security Summit, the signature industry event for chemical representatives across the chemical and interconnected sectors—including energy, communications, transportation, and water—to learn, share perspectives, and engage in dialogue.
