Under DOT regulations, what is the minimum breath alcohol concentration that results in immediate removal from a safety-sensitive function?
Answer: 0.04 g/dL
A confirmed breath alcohol concentration of 0.04 g/dL or greater requires immediate removal from safety-sensitive duties under 49 CFR Part 40.
Which laboratory certification is required for all labs that test federal workplace urine drug specimens?
Answer: SAMHSA/HHS certification under the National Laboratory Certification Program
All federal workplace drug testing laboratories must be certified by SAMHSA/HHS under the National Laboratory Certification Program (NLCP).
A donor states they are taking prescription opioids for chronic pain before a DOT drug test. How should the collector respond?
Answer: Document the disclosure and proceed with the collection normally
The collector proceeds normally — medication disclosures are made to the MRO after a positive result, not to the collector during the collection process.
When must a collector conduct a direct observation collection without waiting for employer authorization?
Answer: When a specimen is reported by the lab as substituted or adulterated and a re-collection is required
A re-collection required because a prior specimen was reported as substituted or adulterated must always be performed under direct observation by regulation.
What does a specimen result of 'substituted' from the laboratory mean?
Answer: The creatinine and specific gravity values indicate the specimen is not consistent with normal human urine
A substituted result means the creatinine level is below 2 mg/dL and the specific gravity is below 1.0010 or above 1.0200, indicating the specimen is not consistent with human urine production.
How many copies does a standard federal five-part Custody and Control Form (CCF) contain, and where does Copy 1 go?
Answer: 5 copies; Copy 1 goes to the laboratory
The federal CCF has five parts; Copy 1 (the original) is sent with the specimen to the testing laboratory to maintain chain of custody.
Under what circumstance may a collector provide a bluing agent (toilet bluing) to a donor prior to specimen collection?
Answer: It is always added to the toilet tank water at collection sites to prevent specimen dilution from toilet water
Toilet bluing agents are required at DOT collection sites to color the toilet water blue, making it obvious if a donor attempts to dilute their specimen with toilet water.
