Dear Valued Customer,

As a trusted partner, Dan-Loc Group is open for business, so you can perform in your business. Based on the DHS standards, Dan-Loc Group is considered an essential and critical business because we support the continued safe operations of pipelines, refineries, chemical plants and other critical manufacturing.

In light of the Stay Home-Work Safe order issued for Harris County, Texas on March 24, 2020, as well as the states of Louisiana and Ohio, we wanted to communicate to you that, as an essential and critical business, Dan-Loc Group has implemented plans to safely remain operational throughout this situation.

A memorandum issued on March 19, 2020, by the Department of Homeland Security’s (DHS) Director of Cybersecurity & Infrastructure Security Agency (CISA), provides guidance as to which businesses, industries and supply chains are considered essential and critical to national resilience during the COVID-19 response. These businesses have a special responsibility and obligation in these times to continue operations.

To that end, Dan-Loc Group has implemented and continues to maintain the following health and safety measures for our employees, customers and suppliers to allow us to continue to support the operations of these key components of our nation’s critical infrastructure:

We continue to stand behind our commitment to provide you with the right product, right service, at the right time.
