§40.193 What happens when an employee does not provide a sufficient amount of urine for a drug test?
Also applies to:
- §40.79 How is the collection process completed?
Question: What is the preferred method for the collector to get the MRO copy of the CCF to the MRO?
Answer:
- The promptness of reporting suffers when the mail is used to convey the MRO copy from the collection site.
- Even though we permit other means (e.g., overnight courier service) of transmitting MRO copies from the collection site to the MRO, collectors should fax the MRO copies when possible.
- If the faxed copy is not legible, the MRO must request another faxed copy or a hard copy.
