Commercial Diving Injuries: Your Rights as an Injured Diver
Commercial diving is among the most dangerous jobs in the maritime world, and when something goes wrong underwater the consequences are often catastrophic or fatal. Commercial diving injuries are also surrounded by a legal trap, because employers routinely tell injured divers they are not covered by the Jones Act when in fact they are.

Key Facts at a Glance
- Commercial divers who work from a vessel in navigation are usually Jones Act seamen, 46 U.S.C. § 30104 (Source: Cornell LII).
- Seaman status turns on a substantial connection to a vessel, generally about 30 percent of work time, Chandris, Inc. v. Latsis, 515 U.S. 347 (1995) (Source: Justia).
- Decompression sickness results from gas bubbles forming in the tissues after a reduction in pressure (Source: MedlinePlus).
- Commercial divers face drowning, respiratory and circulatory problems, and hypothermia, among other hazards (Source: OSHA).
- OSHA’s commercial diving standard, 29 CFR part 1910 subpart T, governs dive teams, procedures, and decompression chambers (Source: eCFR).
- Employers often claim an injured diver is covered only by workers’ compensation to avoid Jones Act liability.
- A Jones Act or unseaworthiness lawsuit generally must be filed within 3 years, 46 U.S.C. § 30106 (Source: Cornell LII).

Commercial divers do underwater what other workers do on deck, and then some: welding, cutting, inspection, salvage, construction, and repair, all while breathing supplied gas at depth in cold, dark, high-pressure conditions. The work supports the offshore oil and gas industry, marine construction, and ship repair, and it carries a risk profile unlike almost any other job. A mistake in gas mixture, decompression schedule, or equipment can injure or kill a diver in minutes. When it does, the question of which law applies determines everything about what the diver or the family can recover.
This guide explains commercial diving injuries from the diver’s side: whether you are a Jones Act seaman, the most common diving injuries, the science and danger of decompression sickness and gas embolism, what causes diving accidents, the safety rules that apply, who can be held liable, and what an injured diver can recover.
Are Commercial Divers Covered by the Jones Act?
Usually yes, but it depends on the diver’s connection to a vessel, and this is the question employers fight hardest. To be a Jones Act seaman, a diver must have a substantial connection to a vessel in navigation, both in duration and nature, which the Supreme Court generally measures at about 30 percent of work time, Chandris, Inc. v. Latsis, 515 U.S. 347 (1995) (Source: Justia). A diver who works offshore from a dive support vessel, provisioned and crewed for diving operations, typically qualifies easily, because the vessel is the base of the work; see what counts as a vessel. A diver who works entirely from shore or fixed structures may not qualify, and freelance divers who move from company to company and between vessels, docks, and platforms fall into a gray area decided by their overall work history. Because employers and insurers often insist a diver is covered only by the Longshore Act or state workers’ compensation, an injured diver should not accept that label without advice.
What Are the Most Common Commercial Diving Injuries?
Diving injuries range from the uniquely pressure-related to the same hazards that threaten any worker in the water. The signature injuries are decompression sickness and arterial gas embolism, both caused by changes in pressure. Beyond those, divers drown when air supply or equipment fails, suffer hypothermia in cold water, sustain barotrauma to the ears, sinuses, and lungs, and are injured by differential pressure, or delta-P, when water moving toward an opening creates suction strong enough to trap and crush. Gas-supply errors can cause hypoxia or toxic exposure, and divers face the same cutting, welding, and heavy-equipment hazards as topside workers. The table below summarizes the main injuries and their causes.
| Injury | Cause |
|---|---|
| Decompression sickness | Gas bubbles forming in tissues after pressure reduction |
| Arterial gas embolism | Lung overexpansion sending air bubbles to the brain |
| Drowning | Air-supply or equipment failure, entrapment |
| Hypothermia | Prolonged exposure to cold water |
| Barotrauma | Pressure damage to ears, sinuses, and lungs |
| Differential pressure (delta-P) | Suction toward an opening that traps the diver |
What Is Decompression Sickness and Why Is It So Dangerous?
Decompression sickness, known as the bends, is the injury most associated with diving, and it can be permanently disabling. It occurs when a diver ascends too quickly and the reduction in pressure causes dissolved gas, chiefly nitrogen, to come out of solution and form bubbles in the blood and tissues (Source: MedlinePlus). Symptoms range from joint pain, fatigue, and numbness to vertigo, breathing difficulty, paralysis, and death, depending on where the bubbles lodge. Treatment requires prompt recompression in a hyperbaric chamber, which is why the safety rules demand a chamber be available at the dive location for certain dives. The danger is compounded offshore, where delays in recognizing symptoms or reaching a chamber can turn a treatable case into permanent neurological injury. Decompression sickness caused by improper dive tables or schedules is frequently a sign of negligence.
What Is Arterial Gas Embolism?
Arterial gas embolism is among the most rapidly lethal diving injuries. It happens when a diver’s lungs overexpand, often from holding the breath during ascent or from a too-rapid ascent, tearing lung tissue and releasing air bubbles into the bloodstream. Those bubbles travel through the heart and can reach the brain, where they block blood flow and produce stroke-like symptoms. An embolism can cause sudden collapse and death at the moment of surfacing, or neurological symptoms that mimic decompression sickness. Like the bends, it is treated with emergency recompression. Because both injuries stem from pressure and ascent, they often point back to failures in dive planning, supervision, or equipment, the very things the safety rules are designed to control.
Decompression and embolism injuries are often the result of negligence, not bad luck. The dive records tell the story.

What Causes Commercial Diving Accidents?
Most serious diving accidents trace back to a failure of planning, procedure, or equipment rather than the diver’s own error. Common causes include improper or experimental decompression schedules that expose divers to the bends, incorrect breathing-gas mixtures, failure to provide or maintain a standby diver and an on-site decompression chamber, equipment and air-supply failures, and inadequate training or supervision. Differential-pressure hazards that were not identified and controlled trap divers against intakes and openings. Ordering a diver into water the company knew or should have known was dangerous, such as a contaminated or high-flow environment, is a recurring source of catastrophic injury. Each of these failures can constitute negligence, and many also violate the federal commercial diving standard, which strengthens an injured diver’s claim.
What Safety Rules Apply to Commercial Diving?
Commercial diving is governed by a detailed federal safety standard. OSHA’s commercial diving operations standard, 29 CFR part 1910 subpart T, sets requirements for the makeup and qualifications of the dive team, a written safe-practices manual, pre-dive planning and procedures, breathing-gas systems, and the availability of decompression chambers for certain dives (Source: eCFR). OSHA identifies drowning, respiratory and circulatory problems, and hypothermia among the core hazards the rules address, and it has issued specific guidance on differential-pressure dangers (Source: OSHA). For an injured diver, these standards matter because a violation, such as diving without a required standby diver, an unavailable chamber, an untrained team, or no proper dive plan, is powerful evidence that the employer was negligent. The dive logs, procedures, and equipment records required by the standard often become the heart of the case.
Who Is Liable for a Commercial Diving Injury?
Liability can reach several parties. A diver who is a seaman can sue the employer under the Jones Act for negligence, including unsafe dive plans, improper decompression schedules, inadequate supervision, defective equipment, and failure to follow the safety standard. The owner of the dive vessel can be liable for unseaworthiness if the vessel, its diving systems, or its crew were not reasonably fit. Third parties can also be responsible: the manufacturer of failed diving equipment, a separate dive contractor, or a facility owner that ordered an unsafe dive. A third-party claim can add significant recovery beyond the employer. Identifying every responsible party is especially important in diving cases, where multiple companies are often involved in a single operation.
Worked example: A diver doing inspection work from an offshore support vessel surfaces with severe joint pain and neurological symptoms after the supervisor cut the decompression stops short to save time. As a Jones Act seaman he sues the employer for negligent decompression procedures, claims unseaworthiness, and receives maintenance and cure during treatment and rehabilitation. If a malfunctioning depth gauge contributed, he may add a third-party claim against its manufacturer.
What Can an Injured Diver Recover?
A commercial diver who is a Jones Act seaman can recover the full value of the harm, which for a catastrophic diving injury is often substantial. Recoverable damages include all past and future medical care, which for neurological injuries from the bends or an embolism can be lifelong; lost wages and lost earning capacity, frequently total when a diver can no longer dive; and compensation for pain, suffering, and disability. Maintenance and cure provides living expenses and medical care from injury until maximum medical improvement, regardless of fault. Where an employer’s conduct was egregious, such as a willful refusal to pay maintenance and cure, punitive damages may be available. A diver who is not a seaman is generally limited to Longshore Act benefits from the employer but may still pursue third parties.

Frequently Asked Questions
Are commercial divers covered by the Jones Act?
Usually, if they work from a vessel. A diver with a substantial connection to a vessel in navigation, generally about 30 percent of work time under Chandris, is a Jones Act seaman. Divers who work entirely from shore or fixed structures may not qualify, and freelance divers fall into a gray area decided by their overall work history.
What is decompression sickness?
Decompression sickness, or the bends, occurs when a diver ascends too quickly and dissolved gas forms bubbles in the blood and tissues. Symptoms range from joint pain and numbness to paralysis and death, and treatment requires prompt recompression in a hyperbaric chamber. It is often caused by improper dive schedules.
What is the difference between the bends and an air embolism?
The bends results from gas bubbles forming in the tissues during ascent, while an arterial gas embolism results from the lungs overexpanding and releasing air into the bloodstream. An embolism can cause stroke-like symptoms and sudden death on surfacing. Both are pressure-related emergencies treated with recompression.
Why does my employer say I’m not a seaman?
Because if you are not a Jones Act seaman, the employer avoids negligence liability and you are limited to no-fault benefits. Employers and insurers often claim a diver is covered only by the Longshore Act or state workers’ compensation. Do not accept that characterization without consulting a maritime attorney, as many vessel-based divers do qualify.
What safety rules apply to commercial diving?
OSHA’s standard at 29 CFR part 1910 subpart T governs commercial diving, covering dive-team qualifications, a safe-practices manual, dive planning, breathing-gas systems, and decompression chambers. A violation, such as no standby diver or an unavailable chamber, is strong evidence that the employer was negligent.
Who is liable for a diving accident?
Often the employer, for negligent dive plans, decompression procedures, supervision, or equipment, and the vessel owner, for unseaworthiness. Third parties such as equipment manufacturers, dive contractors, or facility owners that ordered an unsafe dive can also be liable, and a third-party claim can add to the recovery.
What can I recover for a commercial diving injury?
A diver who is a seaman can recover all past and future medical care, lost wages and earning capacity, and pain and suffering, plus maintenance and cure during recovery. Catastrophic neurological injuries from the bends or an embolism are valued highly. Have your case reviewed to understand your options.
