What unexpected hazards cause illness and injury at sea?

On Behalf of | May 8, 2026 | Jones Act |

Maritime workers know the obvious dangers of their job like falling overboard, getting struck by equipment or slipping on wet decks. You take precautions against these visible risks every day. However, some of the most serious health problems come from hazards you cannot see or might not recognize as dangerous. These hidden dangers can cause illness and injuries that develop slowly over months or years.

Hazards that develop slowly over time

Some workplace exposures damage your health gradually without causing immediate symptoms. You might not realize these dangers exist until serious problems appear:

  • Toxic chemical exposure: Benzene in fuel, asbestos in older ships and chemical fumes from paints or cleaning products can cause cancer and lung disease years after exposure.
  • Constant loud noise: Engine rooms and machinery create noise levels that destroy hearing gradually. Many maritime workers suffer permanent hearing loss they did not notice developing.
  • Vibration from tools: Operating power tools and machinery for hours each day damages nerves and blood vessels in your hands and arms through constant vibration.
  • Sun and UV radiation: Working on deck under direct sunlight for years dramatically increases your risk of skin cancer and serious eye damage.

These hazards cause real injuries even though you cannot see the damage happening in the moment.

Dangers you might not connect to your job

Other health problems stem from working conditions you might accept as normal parts of maritime work. Mold and poor air flow in sleeping quarters cause respiratory problems and chronic illness. Carbon monoxide leaks from engines in enclosed spaces can poison you without obvious warning signs. Long shifts and sleep deprivation increase your accident risk and cause lasting health effects.

The Jones Act and maritime law protect you when these hidden hazards cause illness or injury. Employers must maintain safe working conditions even for dangers that are not immediately obvious. Legal representation can help you prove the connection between your job and health problems that developed over time.
