ADVISORY MEMORANDUM ON IDENTIFICATION OF ESSENTIAL CRITICAL

INFRASTRUCTURE WORKERS DURING COVID-19 RESPONSE

FROM: Christopher C. Krebs

Director

Cybersecurity and Infrastructure Security Agency (CISA)

As the Nation comes together to slow the spread of COVID-19, on March 16th the 

President issued updated Coronavirus Guidance for America that highlighted the

importance ofthe critical infrastructure workforce.

The Cybersecurity and Infrastructure Security Agency (CISA) executes the Secretary of

Homeland Security's authorities to secure critical infrastructure. Consistent with these

authorities, CISA has developed, in collaboration with other federal agencies, State and

local governments, and the private sector, an “Essential Critical Infrastructure Workforce”

advisory list. Thislistisintendedto help State,local,tribal and territorial officials as they work to

protect their communities, while ensuring continuity offunctions critical to public health

and safety, as well as economic and national security. Decisions informed by this list

should also take into consideration additional public health considerations based on the

specific COVID-19-related concerns of particularjurisdictions.

Thislistis advisory in nature.Itis not, nor should it be considered, a federal directive

or standard. Additionally, this advisory list is not intended to be the exclusive list of

critical infrastructure sectors, workers, and functions that should continue during

the COVID-19 response across all jurisdictions. Individual jurisdictions should add

or subtract essential workforce categories based on their own requirements and

discretion.

The advisorylist identifies workers who conduct a range ofoperations and services that are

typically essential to continued critical infrastructure viability, including staffing

operations centers, maintaining and repairing critical infrastructure, operating call centers,

working construction, and performing operational functions, among others. It also

includes workers who support crucial supply chains and enable functions for critical

infrastructure. The industries they support represent, but are not limited to, medical and

healthcare, telecommunications, information technology systems, defense, food and

agriculture, transportation and logistics, energy, water and wastewater, law enforcement,
and public works.

State, local, tribal, and territorial governments are responsible for implementing and 

executing response activities, including decisions about access and reentry, in their

communities, while the Federal Government is in a supporting role. Officials should use

their own judgment in issuing implementation directives and guidance. Similarly, while

adhering to relevant public health guidance, critical infrastructure owners and operators

are expected to use their own judgement on issues of the prioritization of business

processes and workforce allocation to best ensure continuity of the essential goods and 

services they support. All decisions should appropriately balance public safety, the health

and safety of the workforce, and the continued delivery of essential critical infrastructure

services and functions. While this advisory list is meant to help public officials and

employers identify essential work functions, it allows for the reality that some workers

engaged in activity determined to be essential may be unable to perform those functions

because of health-related concerns.

CISA will continue to work with our partners in the critical infrastructure community to

update this advisory list if necessary as the Nation's response to COVID-19 evolves.

Should you have questions about this list, please contact CISA at CISA.CAT@cisa.dhs.gov.

Guidance on the Essential Critical Infrastructure Workforce:

Ensuring Community and National Resilience in COVID-19

Response

Version 2.0 (March 28, 2020)

THE IMPORTANCE OF ESSENTIAL CRITICAL INFRASTRUCTURE WORKERS

Functioning critical infrastructure is imperative during the response to the COVID-19 emergency for both public health

and safety as well as community well-being. Certain critical infrastructure industries have a special responsibility in these

times to continue operations.

This advisory guidance and accompanying list are intended to support state, local, tribal, territorial and industry partners 

in identifying the critical infrastructure sectors and the essential workers needed to maintain the services and functions

Americans depend on daily and that need to be able to operate resiliently during the COVID-19 pandemic response.

This document gives advisory guidance on defining essential critical infrastructure workers. Promoting the ability of such

workers to continue to work during periods of community restriction, access management, social distancing, or closure 

orders/directives is crucial to community resilience and continuity of essential functions.

CISA will continually solicit and accept feedback on the list and will evolve the list in response to stakeholder feedback.

We will also use our various stakeholder engagement mechanisms to work with partners on how they are using this list

and share those lessons learned and best practices broadly. Feedback can be sent to CISA.CAT@CISA.DHS.GOV.

CONSIDERATIONS FOR GOVERNMENT AND BUSINESS

This list was developed in consultation with federal agency partners, industry experts, and State and local officials, and

is based on several key principles:

1. Response efforts to the COVID-19 pandemic are locally executed, state managed, and federally supported.

2. Everyone should follow guidance from the CDC, as well as State and local government officials, regarding

strategies to limit disease spread.

3. Workers should be encouraged to work remotely when possible and focus on core business activities. Inperson, non-mandatory activities should be delayed until the resumption of normal operations.

4. When continuous remote work is not possible, businesses should enlist strategies to reduce the likelihood of

spreading the disease. This includes, but is not necessarily limited to, separating staff by off-setting shift hours

or days and/or social distancing. These steps can preserve the workforce and allow operations to continue.

5. All organizations should implement their business continuity and pandemic plans or put plans in place if they

do not exist. Delaying implementation is not advised and puts at risk the viability of the business and the
health and safety of the employees.

6. Reliance on technology and just-in-time supply chains means that certain workers must be able to access

certain sites, facilities, and assets to ensure continuity of functions.

7. Government employees, such as emergency managers, and the business community need to establish and

maintain lines ofcommunication.

8. When government and businesses engage in discussions about essential critical infrastructure workers,they

need to consider the implications of business operations beyond the jurisdiction where the asset or facility is

located. Businesses can have sizeable economic and societal impacts as well as supply chain dependencies

that are geographicallydistributed.

9. Whenever possible, jurisdictions should align access and movement control policies related to critical

infrastructureworkers to lowerthe burden of workers crossing jurisdictionalboundaries.
