Antwerp Port Chemical Leak: 155 Hospitalized, 1 in ICU

Massive Chemical Leak in Port of Antwerp Leaves Dozens Hospitalized

A major chemical leak involving hydrogen fluoride aboard the cargo vessel Mia Summer II at the Port of Antwerp's Deurganck Dock has left 155 people requiring medical evaluation, with 29 hospitalized and one person in intensive care. The incident, which occurred on the evening of July 14, 2026, has prompted a large-scale emergency response and temporarily shut down port operations in the affected area.

Hydrogen fluoride (HF) is a highly toxic, colorless gas that can cause severe respiratory damage, chemical burns, and even death upon exposure. According to the CDC, HF can penetrate skin deeply and destroy cells, leading to systemic toxicity. Symptoms may include eye and respiratory irritation, pulmonary edema, and cardiac arrhythmias.

What Happened During the Antwerp Port Chemical Leak?

The leak was discovered around 9:30 p.m. local time on Tuesday, July 14, aboard the cargo ship Mia Summer II while it was berthed at the MSC PSA European Terminal (MPET) in the Deurganck Dock, part of the Waaslandhaven. A container carrying hydrogen fluoride had developed a hole approximately 10 centimeters in diameter, allowing the toxic gas to escape and vaporize.

Emergency services immediately established a safety perimeter around Quay 1742, evacuated the vessel, and began medical screening of all personnel in the vicinity. The Belgian emergency response protocols were activated, including the closure of bridges near the Kieldrecht Lock and a temporary halt to all ship traffic in the area.

Casualties and Medical Response

Of the 155 people who underwent medical checks, 29 were admitted to hospitals across the region. One patient remains in intensive care with serious injuries. Most of those affected were dockworkers and crew members, many of whom are from the Philippines. According to Anadolu Agency, reports also emerged of a chemical tank catching fire aboard the vessel during the incident, though this has not been officially confirmed.

Local authorities have urged residents and workers to avoid the surrounding area. The mayor of Beveren-Kruibeke-Zwijndrecht, under whose jurisdiction the Waaslandhaven falls, stated that the situation is currently under control and that efforts to seal the leak are ongoing.

Health Risks of Hydrogen Fluoride Exposure

Hydrogen fluoride is one of the most dangerous industrial chemicals. When inhaled, it can cause immediate respiratory distress, and delayed symptoms such as pulmonary edema may appear hours after exposure. Skin contact leads to deep, painful burns that can continue to damage tissue for days if not treated promptly with calcium gluconate gel.

The global chemical transport safety standards are under renewed scrutiny following this incident. Experts emphasize that proper container inspection and maintenance are critical to preventing such leaks.

Long-Term Environmental Concerns

While the immediate health impacts are the primary concern, environmental groups are calling for an assessment of potential contamination of the Scheldt River and surrounding ecosystems. Hydrogen fluoride can form hydrofluoric acid upon contact with moisture, posing risks to aquatic life and water quality. The Port of Antwerp-Bruges has stated that air quality monitoring is ongoing and that no significant environmental contamination has been detected so far.

Impact on Port Operations and Trade

The Deurganck Dock is one of the busiest container terminals in Europe, handling millions of TEUs annually. The temporary shutdown of operations at the affected quay has caused delays in cargo handling and vessel schedules. Shipping companies have been advised to reroute vessels until further notice. The European port security and chemical handling regulations are expected to be reviewed in the wake of this incident.

Economic analysts estimate that disruptions at the Port of Antwerp could cost millions of euros per day in lost trade and logistics delays. The port authority has assured stakeholders that operations will resume as soon as it is safe to do so.

Frequently Asked Questions

What is hydrogen fluoride?

Hydrogen fluoride (HF) is a highly corrosive, colorless gas or liquid used in industrial processes such as producing refrigerants, pharmaceuticals, and aluminum. It is extremely toxic and can cause severe burns and respiratory damage.

How did the leak happen?

A container aboard the cargo ship Mia Summer II developed a hole approximately 10 cm in diameter, allowing hydrogen fluoride gas to escape. The cause of the damage is still under investigation.

How many people were affected?

155 people underwent medical checks. 29 were hospitalized, with one person in intensive care. Most have since been discharged.

Is the situation under control?

Yes. Local authorities have stated that the leak is being contained, emergency services have sealed the area, and the situation is under control. Air quality monitoring is ongoing.

What should I do if I was in the area?

If you experience symptoms such as coughing, eye irritation, or difficulty breathing, seek medical attention immediately. Avoid the affected zone and follow instructions from local authorities.
