Why Maritime Employers Choose Us
Frequently Asked Questions
What regulations govern maritime drug testing?
Maritime drug testing is governed by the U.S. Coast Guard under 46 CFR Part 16 for vessel crewmembers, and by DOT under 49 CFR Part 40 for testing procedures. Maritime employers must comply with both frameworks. Do It Right Screening manages full compliance under both.
Who is required to undergo maritime drug testing?
USCG regulations require testing for individuals holding or applying for a Merchant Mariner Credential (MMC), crewmembers on inspected vessels, and employees in safety-sensitive maritime positions including vessel operators, engineers, deck officers, and able seamen.
What is a TWIC and does it require drug testing?
The Transportation Worker Identification Credential (TWIC) is required for workers needing unescorted access to secure maritime areas. While TWIC itself does not mandate drug testing, workers in safety-sensitive positions are subject to USCG testing requirements. We provide qualified TWIC drug collection services.
What types of maritime drug testing are required?
Maritime employers must conduct pre-employment, random, post-incident, reasonable cause, return-to-duty, and follow-up testing. Do It Right Screening manages all required test types and maintains the documentation needed for USCG audits.
How does maritime drug testing differ from standard DOT testing?
The testing procedure (5-panel urine test, chain of custody, MRO review) is the same under 49 CFR Part 40. The key difference is that maritime employers are also subject to USCG-specific rules under 46 CFR Part 16, including requirements tied to Merchant Mariner Credentials and vessel operations.
