Organization, Consolidation and Presentation of Financial Statements [Abstract] |
BASIS OF PRESENTATION | BASIS OF PRESENTATION The accompanying consolidated interim financial statements are unaudited and include the accounts of Clean Harbors, Inc. and its subsidiaries (collectively, “Clean Harbors,” the “Company” or "we") and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) and, in the opinion of management, include all adjustments which are of a normal recurring nature and are necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented. Management has made estimates and assumptions affecting the amounts reported in the Company's consolidated interim financial statements and accompanying footnotes; actual results could differ from those estimates and judgments. The results for interim periods are not necessarily indicative of results for the entire year or any other interim periods. The financial statements presented herein should be read in conjunction with the financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. A novel strain of coronavirus ("COVID-19") was first identified in December 2019, and subsequently declared a global pandemic by the World Health Organization on March 11, 2020. As a result of the outbreak, many companies have experienced disruptions in their operations, workforce and markets served, including a significant reduction in the demand for petroleum-based products. The Company's businesses and operations began being adversely impacted by effects of COVID-19 in March of 2020 when circumstances surrounding and responses to the pandemic, including stay-at-home orders, began to materialize in North America. These disruptions are expected to have a significant adverse impact on the Company's operating results during the second quarter of 2020 and the remainder of the year. The full extent of the COVID-19 outbreak and changes in demand for oil and the impact on the Company’s operations is uncertain. A prolonged disruption could have a material adverse impact on financial results and business operations of the Company. In addition and in response to the COVID-19 outbreak, the Company has seen increased demand in emergency response services. Specifically the Company is addressing the safety of its customers and communities by providing contagion decontamination services. In conducting these services, employee safety is paramount and the Company has been able to provide appropriate personal protective equipment and support to those performing these services.
