Maritime Outreach Is Classroom-Only

OSHA Outreach Training Program

The OSHA 30 Maritime course is for shipyard, marine terminal, and longshoring workers with supervisory or safety responsibility. It is classroom training — minimum 4 days, maximum 7.5 hours per day, no authorized online option — taught by an OSHA-authorized maritime outreach trainer for roughly $400-$800. Content goes deep into 29 CFR 1915 (shipyards), 1917 (marine terminals), and 1918 (longshoring): confined and enclosed space entry with the 19.5%-22.0% oxygen range and below-10%-LEL criterion, Marine Chemist Safe-for-Hot-Work certificates, fire watches when combustibles are within 35 feet, the 5-foot shipyard fall protection trigger and PFDs over water, rigging and crane load rules, asbestos/lead/hexavalent chromium exposure limits, lockout/tags-plus under 1915.89, and 29 CFR 1904 recordkeeping with 8-hour fatality reporting. There is no standardized national exam — trainers administer topic quizzes and verify attendance, then issue the DOL card, which does not expire. Practicing exam-style questions on the specific numbers and certificate rules is the fastest way to retain the material.

C.Eliminate every conceivable hazard, whether or not it is recognized in the maritime industry
D.Comply only with the specific maritime standards in 29 CFR Parts 1915, 1917, and 1918
Explanation: Section 5(a)(1) requires employers to furnish employment free from recognized hazards causing or likely to cause death or serious physical harm. OSHA uses it to cite serious maritime hazards not covered by a specific standard.
2A longshore worker is fired two days after complaining to OSHA about unguarded deck openings. Under Section 11(c) of the OSH Act, how many days does the worker have to file a whistleblower retaliation complaint with OSHA?
A.10 days
B.180 days
C.30 days
D.90 days
Explanation: Section 11(c) of the OSH Act gives workers 30 calendar days from the retaliatory action to file a whistleblower complaint with OSHA.
3A rigger is struck by a swinging cargo draft and is admitted to the hospital as an in-patient. Under 29 CFR 1904.39, within how many hours of learning of the hospitalization must the employer report it to OSHA?
A.8 hours
B.12 hours
C.48 hours
D.24 hours
Explanation: 29 CFR 1904.39 requires employers to report any work-related in-patient hospitalization, amputation, or loss of an eye to OSHA within 24 hours of learning about it.
4During what period must a marine terminal employer post the OSHA Form 300A annual summary of work-related injuries and illnesses?
A.February 1 through April 30 of the year following the year covered
B.January 1 through March 1
C.February 1 through March 31
D.Continuously throughout the entire calendar year
Explanation: 29 CFR 1904.32 requires the certified Form 300A summary to be posted in a conspicuous place from February 1 through April 30 of the year following the year covered by the records.
5How long must a shipyard retain its OSHA 300 Logs, 301 Incident Reports, and 300A summaries?
A.1 year from the date of the last entry
B.5 years following the end of the calendar year the records cover
C.3 years from the date of each injury
D.30 years, the same as employee exposure records
Explanation: 29 CFR 1904.33 requires injury and illness records to be saved for 5 years following the end of the calendar year they cover, with 300 Logs updated during that period.
6After a recordable injury occurs on the pier, within how long must the employer complete the OSHA Form 301 Injury and Illness Incident Report?
A.30 calendar days
B.24 hours
C.7 calendar days
D.10 working days
Explanation: 29 CFR 1904.29(b)(3) requires the employer to complete the OSHA 301 incident report (or equivalent) within 7 calendar days of receiving information that a recordable case occurred.

A.A small cut treated only by cleaning and an adhesive bandage
B.A laceration closed with sutures
C.A back strain resulting in two days of restricted work
D.A flash burn that causes a brief loss of consciousness
Explanation: Cases treated only with first aid — such as cleaning a wound and applying a bandage — are not recordable under 29 CFR 1904.7. Recording is triggered by medical treatment beyond first aid, restricted work, days away, or loss of consciousness.
8A shipfitter is crushed by plate steel and dies from the injuries 18 days later. What does 29 CFR 1904.39 require the employer to do?
A.Nothing, because the death occurred more than a week after the incident
B.Report the death within 24 hours
C.Report only if OSHA opens an inspection of the shipyard
D.Report the fatality to OSHA within 8 hours of learning of it, because the death occurred within 30 days of the incident
Explanation: A fatality must be reported within 8 hours if the death occurs within 30 days of the work-related incident. At 18 days, this death is reportable within 8 hours of the employer learning of it.
9What is the primary purpose of a workplace incident investigation in a shipyard safety program?
A.To determine which employee should be disciplined for the event
B.To identify root causes and system failures so similar incidents can be prevented
C.To satisfy the insurance carrier's claims documentation requirements
D.To document that the injured employee violated a written safety rule
Explanation: Effective incident investigations look past the immediate act to root causes — failed defenses, missing procedures, inadequate training — so corrective actions prevent recurrence. Blame-focused investigations suppress reporting.
10An employee asks for a copy of the current OSHA 300 Log. Under 29 CFR 1904.35, when must the employer provide it?
A.Within 30 calendar days
B.Within 7 calendar days

OSHA 30 Maritime: Suggested Study Strategy

1Memorize the atmosphere numbers as a set: oxygen acceptable from 19.5% to 22.0%, flammables below 10% of the LEL, and CO at 50 ppm (8-hour average) with removal above 100 ppm under 1917.24 — they anchor every confined space question.
2Keep the trigger heights straight: shipyard fall protection starts at 5 feet (1915.73), versus 4 feet in general industry and 6 feet in construction; guardrail top rails sit at about 42 inches.
3Know when a Marine Chemist is required (hot work in spaces that contain or contained flammable liquids or gases, 1915.14) versus when a shipyard competent person can authorize work, and that the certificate must be posted near the operation.
4For fire protection, tie the fire watch to its triggers — combustibles within 35 feet, sparks passing through openings — and remember the watch continues at least 30 minutes after the hot work unless a survey clears the area.
5Drill the rigging removal criteria: 10 broken wires in one rope lay or 5 in one strand for wire rope slings, 15% throat opening growth or 10-degree twist for hooks, and remember leg tension doubles as sling angles flatten to 30 degrees.
6Learn the 1904 reporting clocks cold: fatalities within 8 hours (if death occurs within 30 days of the incident), in-patient hospitalizations, amputations, and eye losses within 24 hours, Form 301 within 7 calendar days, and 300A posting February 1 to April 30.

Frequently Asked Questions

What is the OSHA 30-Hour Maritime Outreach course?

It is the supervisory-level course in OSHA's Outreach Training Program for the maritime industry, covering shipyard employment (29 CFR 1915), marine terminals (1917), and longshoring (1918). Students who complete all 30 hours with an authorized maritime outreach trainer receive a U.S. Department of Labor course-completion card.

Can I take OSHA 30 Maritime online?

No. Unlike the construction and general industry courses, OSHA has not authorized any online provider for maritime outreach training. The course must be taken in person from a trainer authorized through an OSHA Outreach Training Program education center, over a minimum of 4 days with no more than 7.5 hours of training per day.

Is there a final exam for the OSHA 30 Maritime card?

There is no standardized national exam. Authorized trainers administer their own end-of-topic quizzes and exercises, verify satisfactory performance and full 30-hour attendance, and then request the DOL card through their authorizing training organization. Practice questions on the regulatory numbers and certificate rules make the trainer assessments straightforward.

Who should take the 30-hour maritime course instead of the 10-hour?

The 30-hour course is designed for workers with supervisory or safety responsibility — foremen, leadmen, gang bosses, ship superintendents, and safety personnel in shipyards, marine terminals, and longshoring operations. The 10-hour course is entry-level awareness training for workers without those responsibilities.

What topics make maritime outreach different from general industry?

Maritime-specific content includes confined and enclosed space entry under 1915 Subpart B with Marine Chemist Safe-for-Hot-Work certificates, the 5-foot shipyard fall protection trigger, working over water with PFDs and ring buoys, vessel access by gangways and Jacob's ladders, cargo gear certification, container top fall protection, and the lockout/tags-plus system of 1915.89.

Does the OSHA 30 Maritime card expire?

The DOL card itself does not expire under federal rules, but many shipyards, terminal operators, and port authorities require refresher training every 3 to 5 years as a condition of site access or supervisory assignment.

How much does the OSHA 30 Maritime course cost?

Pricing is set by the authorized trainer or education center, typically about $400 to $800 per student depending on location and whether the class is open-enrollment or delivered on site for an employer.
