ChemLock wordmark and icon. Icon is a lock with a shield; within the shield is a beaker containing chemicals. Know Your Chemicals. Lock in your security posture.More than 96% of all manufactured goods depend on chemicals in some way. These chemicals are used, manufactured, stored, and transported across global supply chains, forming the bedrock of industries that touch nearly every aspect of American life—from microchips to food processing. Many of these chemicals that businesses interact with every day are dangerous chemicals that could be used in a terrorist attack.

Whether a small business or an international company, everyone who interacts with these chemicals has a role to play in understanding the risk and taking collective action to prevent chemicals being weaponized by terrorists. 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 that works for their business model.

To request any of CISA ChemLock’s no-cost services and tools, please fill out the ChemLock Services Request Form.

Announcement: CISA is now offering the ChemLock: Introduction to Chemical Security training course on a quarterly basis. To learn more, visit the ChemLock Training webpage. If you are interested in having a training for your facility's personnel, please submit a request through the ChemLock Services Request Form.

Chemical Threat and Risk

Venn diagram with threat, vulnerability, and consequence overlapping. In the middle where all three circles are overlapping is risk.Facilities with dangerous chemicals have long been attractive targets for terrorists around the world who aspire to conduct sensational attacks that could potentially cause a significant number of deaths and injuries. Threats include physical attacks, theft or diversion of chemicals, cyberattacks, unauthorized drone activity, and malicious activities by facility personnel, among others.

The risk of an unwanted outcome resulting from an incident or event involving dangerous chemicals has three components: the threat of a dangerous chemical being weaponized, the vulnerability of the facility to an attack, and the consequences of an incident if the threat were to occur. Mitigating any of these three components lowers the specific risks that on-site chemicals present.

CISA’s Chemical Security Expertise

CISA is a recognized international leader in chemical security with more than a decade of experience assisting facilities in building tailored security plans to prevent terrorist exploitation of their chemicals. From on-site consultations to chemical security publications, the CISA ChemLock program offers scalable, tailored options for facilities looking to enhance their chemical security posture.

Chemical Facility Anti-Terrorism Standards (CFATS)

Participation in any portion of CISA’s ChemLock program does not replace any reporting or compliance requirements under CISA’s Chemical Facility Anti-Terrorism Standards (CFATS) regulation (6 CFR part 27). Some ChemLock activities may fulfill CFATS requirements, depending on your specific security plan.
