Daegu Food Factory Incident: 8 Hospitalized After Carbon Dioxide Leak

Carbon Monoxide Incident at Daegu Food Processing Plant: Ventilation Failure Blamed

Daegu, South Korea – An incident involving elevated carbon monoxide levels occurred at a food processing plant in Samri-ri, Nongong-eup, Dalseong-gun, Daegu, on July 23rd, prompting an emergency response and temporary evacuation measures. Eight individuals, including factory personnel, reported symptoms such as dizziness and headaches and were transported to a nearby hospital for treatment. Fortunately, all affected individuals are reported to be in stable condition with no life-threatening injuries.

The incident, which originated around 11:47 AM, was attributed to a malfunction in the factory’s ventilation system. Reports indicate that while working on the food factory’s oven equipment, the ventilation facility failed. This breakdown led to a buildup of carbon monoxide within the facility, as the gas could not be properly discharged. Consequently,the carbon monoxide concentration exceeded safe levels,leading to the complaints of ill health among employees.

In response to the situation, over 50 personnel, including representatives from local government, the fire department, and police, were dispatched to the site to manage the unfolding events. The Daegu Regional Employment and Labor office promptly issued an order to the factory, and an inquiry into the cause of the accident commenced instantly.

As a precautionary measure, Dalseong-gun issued an urgent advisory to local residents at 12:20 PM, warning of a gas leak and advising them to cease using ventilation facilities, close windows, and block any openings. This advisory was lifted at 2:26 PM after authorities confirmed the situation was contained and the evacuation status concluded.

Crucially, investigations by the Korea Gas Safety Corporation have confirmed that there was no external leak of carbon monoxide from the factory. The faulty ventilation system was identified as the sole cause of the internal accumulation of the risky gas.

Carbon monoxide, a colorless and odorless gas, can be fatal if inhaled in high concentrations over prolonged periods.Health authorities emphasize the importance of adequate ventilation when using heating devices or in enclosed spaces.

A fire official stated that the incident was indeed caused by carbon monoxide exposure resulting from issues with the factory’s internal fans. The factory has since undergone an investigation, and authorities have concluded their on-site assessment.

What specific safety protocols were in place at the Daegu food factory regarding regular inspections of CO2 storage tanks and piping?

Understanding the Incident & Immediate response

On July 23, 2025, a important carbon dioxide leak occurred at a food processing factory in Daegu, South Korea, resulting in the hospitalization of eight workers. Initial reports indicate the leak stemmed from a malfunction in the facility’s CO2 storage system, used for food preservation and carbonation processes. Emergency services were dispatched to the scene at approximately [Insert Time if available – research needed], and the affected area was quickly evacuated.

The eight individuals hospitalized were reportedly experiencing symptoms consistent with carbon dioxide poisoning, including:

Difficulty breathing

Headaches

Dizziness

Loss of consciousness

Local hospitals are providing treatment, including oxygen therapy, to stabilize the patients.The severity of their conditions varies, with some reported to be in critical but stable condition. Industrial accidents like this highlight the importance of robust safety protocols.

Carbon Dioxide: The Invisible Hazard in Food Production

Carbon dioxide (CO2) is widely used in the food industry for several purposes, making incidents like this a potential risk in many facilities. Common applications include:

Carbonated Beverages: The most recognizable use, providing the fizz in sodas and sparkling water.

Food Packaging: Modified Atmosphere Packaging (MAP) utilizes CO2 to extend the shelf life of perishable foods by inhibiting bacterial growth.

Cryogenic Freezing: Liquid CO2 is used for rapid freezing of food products,preserving quality and texture.

Meat Processing: CO2 is used in stunning animals before slaughter,and in packaging to maintain colour and freshness.

Though,CO2 is an asphyxiant gas.This means it displaces oxygen in the air, leading to oxygen deprivation. As it’s heavier than air, it can accumulate in low-lying areas, creating a particularly dangerous surroundings. Unlike some toxic gases, CO2 is odorless and colorless, making leaks arduous to detect without specialized equipment. CO2 safety measures are therefore crucial.

Investigating the Cause: Potential Factors & Regulatory Oversight

Authorities are currently investigating the root cause of the Daegu factory leak. Preliminary investigations are focusing on:

1. Equipment Failure: A malfunction in the CO2 storage tank, valves, or piping system.
2. Maintainance Issues: Lack of regular inspections and maintenance of the CO2 system.
3. Ventilation Problems: Inadequate ventilation in the affected area,allowing CO2 to accumulate.
4. Human Error: Potential errors in operating procedures or handling of the CO2 system.

the incident will likely trigger a review by the Korean ministry of Employment and Labor (MOEL) to ensure compliance with industrial safety regulations.these regulations mandate:

Regular safety inspections of CO2 systems.

Proper ventilation in areas were CO2 is used or stored.

Employee training on CO2 hazards and emergency procedures.

The use of CO2 detectors and alarm systems.

Similar Incidents & Lessons learned: A Global Perspective

Unfortunately, carbon dioxide leaks in food facilities are not uncommon globally. Several incidents have occurred in recent years, highlighting the need for improved safety standards.

2022 – Louisiana, USA: A CO2 leak at a beverage plant sent several workers to the hospital.

2021 – Germany: A similar incident occurred at a brewery, prompting stricter safety regulations.

2019 – florida,USA: A CO2 leak at a food processing plant resulted in fatalities.

These cases underscore the importance of proactive safety measures, including:

Gas Detection Systems: Implementing reliable CO2 monitoring systems with alarms.

Emergency Response Plans: Developing and regularly practicing emergency evacuation and rescue procedures.

Engineering controls: Designing facilities with adequate ventilation and containment systems.

Personal Protective Equipment (PPE): Providing workers with appropriate respirators and other PPE.

Protecting Workers: Best Practices for CO2 Safety

Preventing future incidents requires a multi-faceted approach focused on worker safety and regulatory compliance. Key recommendations include:

Extensive Training: All employees working with or near CO2 systems should receive thorough training on the hazards, safe handling procedures, and emergency response protocols.

Regular Inspections: Conduct routine inspections of CO2 storage tanks, piping, and ventilation systems to identify and address potential problems.

Preventative Maintenance: Implement a preventative maintenance program to ensure all CO2 equipment is functioning properly.

Ventilation Assessment: Evaluate the ventilation system to ensure it can effectively remove CO2 in the event of a leak.

Emergency Drills: Conduct regular emergency drills to familiarize workers with evacuation procedures and the use of emergency equipment.
