Drug and alcohol screening programs are necessary in many workplaces, especially in transportation, where federal regulations mandate testing for employees performing safety-sensitive functions. The Designated Employer Representative (DER) serves as the company’s single, authorized point of contact for managing this process. The DER’s role is to ensure regulatory compliance and act swiftly on behalf of the employer, making them central to the entire testing operation.
Defining the Designated Employer Representative
The Designated Employer Representative (DER) is an employee authorized by their company to oversee and manage all aspects of the drug and alcohol testing program. This person acts as the official liaison between the employer and all external service agents involved in the testing process, including collection sites, laboratories, Medical Review Officers (MROs), and Substance Abuse Professionals (SAPs). For Department of Transportation (DOT) regulated companies, the DER role is formally defined within 49 CFR Part 40.
The DER must be an actual employee of the company, not an outsourced contractor or service agent, to maintain the integrity of the program and the employer’s authority. This regulation grants the DER the authority to make immediate and necessary decisions regarding the testing and evaluation process. This includes the power to immediately remove an employee from safety-sensitive duties when required by regulation. This authority ensures swift action is taken to protect public safety and maintain compliance.
Mandatory Responsibilities During Testing
The DER’s duties involve careful coordination of various resources, beginning before an employee is tested. A primary responsibility is the selection and oversight of qualified service agents, such as specimen collectors and breath alcohol technicians. The DER must ensure these external providers adhere to the strict procedural requirements outlined in 49 CFR Part 40 to maintain the legal defensibility of the tests.
The DER is responsible for the procedural management of testing events, ensuring proper notification for all types of required tests. This includes coordinating the scheduling for pre-employment, post-accident, reasonable suspicion, and random testing. For random testing, the DER must maintain an accurate employee pool and ensure the selection process complies with required testing rates set by the specific DOT operating agency. Furthermore, the DER is accountable for maintaining all testing records, ensuring they are organized, complete, and readily available for potential audits.
Handling Test Results and Consequences
The DER’s most serious responsibilities involve receiving and acting upon verified test results provided by the Medical Review Officer (MRO). Once the MRO confirms a violation, such as a positive drug test or a refusal to test, the DER is the official recipient of this confidential information. The DER must then take immediate action to notify the employee of the confirmed violation.
The paramount duty is the immediate removal of the employee from all safety-sensitive functions. The employee cannot return to these duties until they successfully complete the return-to-duty process, which involves a mandatory evaluation by a qualified Substance Abuse Professional (SAP). The DER initiates this process by providing the employee with a list of SAPs. The DER must also ensure that required information, such as positive drug tests or refusals, is reported to the appropriate federal databases, like the FMCSA Drug and Alcohol Clearinghouse.
Requirements for the DER Role
To effectively manage a regulated testing program, the DER must possess a thorough and current understanding of the applicable regulations. The central requirement is in-depth knowledge of 49 CFR Part 40, which governs the testing process for DOT-regulated industries. The DER must be trained to recognize specific prohibited conduct and the precise consequences tied to various test outcomes.
The role also carries strict limitations to prevent conflicts of interest and maintain the integrity of the testing chain. A service agent, such as a Third-Party Administrator (TPA), is explicitly prohibited from acting as the DER for an employer. While the DER makes administrative decisions, they cannot override the medical or scientific determinations made by the MRO regarding a verified test result. This separation of duties ensures that medical determinations remain independent of employer policy decisions.
