Final answer:
A safety-sensitive employee must proceed to the specimen collection site immediately after being notified by a supervisor or DER for drug testing. Employers must provide safety training, perform workplace tests, and keep accurate records in compliance with OSHA standards.
Step-by-step explanation:
When a safety-sensitive employee is notified by a supervisor or Designated Employer Representative (DER) for drug testing, they must proceed to the specimen collection site immediately. Employers are required to not only provide safety training but also to ensure that procedures for workplace health, such as drug testing, are followed promptly. This is part of the employer's responsibilities to perform tests in the workplace and to adhere to Occupational Safety and Health Administration (OSHA) standards for a safe working environment. Employers are also responsible for keeping accurate records of work-related injuries and illnesses as part of their regulatory compliance.
