From the Overview: "Whether a small business or an international company, everyone who interacts with dangerous chemicals has a role to play in understanding the risk and taking collective action to prevent chemicals being weaponized by terrorists. The Cybersecurity and Infrastructure Security Agency (CISA) encourages facilities with dangerous chemicals to develop and implement a holistic security plan to reduce the risk that dangerous chemicals are exploited. An important aspect of implementing a facility security plan is regular self-assessment. This guidance provides recommendations on how to systematically review a facility security plan."
