Chemical Warfare: Examining the Devastating Impact of Ethyl Acetate Weapons

The use of chemical weapons is a grave violation of international law, with devastating consequences for both combatants and civilians. While many associate chemical warfare with notorious agents like mustard gas and sarin, the potential use of seemingly innocuous chemicals like ethyl acetate as weapons raises serious concerns. In 2025, reports emerged of ethyl acetate being deployed in airstrikes on civilian targets in South Sudan, resulting in numerous casualties and sparking international condemnation. This incident underscores the urgent need to examine the devastating impact of ethyl acetate weapons and the legal ramifications of their use.

What is Ethyl Acetate?

Ethyl acetate (C4H8O2) is a colorless, flammable liquid with a sweet, fruity odor. It is a common solvent used in a wide range of industrial and consumer products, including:

  • Paints and coatings
  • Adhesives
  • Nail polish remover
  • Cleaning fluids
  • Food flavorings
  • Perfumes

Due to its low cost, low toxicity, and agreeable odor, ethyl acetate is favored as a solvent and diluent in various applications. However, its flammability and potential health hazards when mishandled make it a substance of concern, especially in the context of weaponization.

The Devastating Impact of Ethyl Acetate as a Weapon

While ethyl acetate is not specifically designed as a weapon, its properties can be exploited to cause significant harm. When used in attacks, ethyl acetate can have devastating effects:

  • Incendiary Effects: Ethyl acetate is highly flammable, and its vapors can form explosive mixtures with air. When ignited, it can cause widespread fires and severe burns, as witnessed in the South Sudan incident where at least 21 people were killed, including the paramount chief, and the airport, market, and county commissioner’s residence were targeted.
  • Respiratory Irritation: Inhalation of ethyl acetate vapors can irritate the respiratory tract, causing coughing, sore throat, and shortness of breath. High-level exposure can lead to more severe respiratory problems, including bronchitis and other lung conditions.
  • Central Nervous System Effects: Ethyl acetate can affect the central nervous system if inhaled in large quantities. Symptoms of overexposure may include headaches, dizziness, drowsiness, and in extreme cases, unconsciousness.
  • Eye and Skin Irritation: Direct contact with ethyl acetate can cause irritation, redness, tearing, and blurred vision in the eyes. Skin contact can lead to dryness, cracking, redness, itching, and swelling (dermatitis).
  • Internal Organ Damage: Prolonged or repeated exposure to ethyl acetate can have toxic effects on the liver and kidneys.

Legal and Ethical Considerations

The use of ethyl acetate as a weapon raises serious legal and ethical concerns under international law. Several international agreements and conventions address the use of chemical weapons and the protection of civilians in armed conflict.

  • Chemical Weapons Convention (CWC): The CWC is a comprehensive treaty that prohibits the development, production, stockpiling, and use of chemical weapons. While ethyl acetate is not explicitly listed as a prohibited chemical, its use as a weapon could be a violation of the CWC if it is determined to be a toxic chemical used to cause death or serious injury.
  • Convention on Certain Conventional Weapons (CCW): The CCW prohibits or restricts the use of specific types of weapons that are deemed to cause unnecessary suffering or indiscriminate effects. Protocol III of the CCW addresses incendiary weapons, and the use of ethyl acetate as an incendiary weapon could be a violation of this protocol.
  • Customary International Law: Customary international law prohibits the use of weapons that cause unnecessary suffering or are indiscriminate in their effects. The use of ethyl acetate in a manner that deliberately or indiscriminately targets civilians would violate these principles.
  • Geneva Protocol of 1925: This protocol prohibits the use in war of asphyxiating, poisonous or other gases, and of bacteriological methods of warfare.

The legality of using ethyl acetate in warfare hinges on its deployment. International law is violated if it is used to deliberately or indiscriminately target civilians, resulting in widespread fires and uncontrollable damage. The intentional nature of the strike, military involvement, and civilian casualties raise concerns about compliance with international legal standards and the protection of civilians.

Ethyl Acetate vs. Riot Control Agents

It’s important to distinguish ethyl acetate from riot control agents (RCAs) like tear gas. While RCAs are designed to cause temporary incapacitation, ethyl acetate’s primary danger in warfare stems from its flammability and potential to cause severe burns and widespread fires.

The use of RCAs as a method of warfare is prohibited under customary international law. This prohibition is rooted in the concern that using tear gas, for example, in armed conflict “runs the danger of provoking the use of other more dangerous chemicals”. A party attacked by RCAs might mistakenly believe they are under attack by deadly chemical weapons and retaliate with chemical weapons. This risk of escalation is what states sought to avoid by prohibiting the use of riot control agents as a method of warfare in armed conflict.

Advice

Given the potential for misuse and the devastating consequences of ethyl acetate when weaponized, strict regulations and controls are necessary. Governments and international organizations should:

  • Strengthen regulations: Implement stricter regulations on the production, storage, and sale of ethyl acetate to prevent its diversion for use as a weapon.
  • Enhance monitoring: Improve monitoring and detection capabilities to identify and prevent the illicit use of ethyl acetate in conflict zones.
  • Investigate alleged uses: Thoroughly investigate any allegations of ethyl acetate being used as a weapon and hold perpetrators accountable.
  • Promote awareness: Raise awareness among military personnel, policymakers, and the public about the dangers of ethyl acetate weaponization and the legal and ethical implications of its use.
  • Support victims: Provide medical and psychological support to victims of ethyl acetate attacks and ensure they have access to justice and redress.

Conclusion

The use of ethyl acetate as a weapon is a serious violation of international law and a grave threat to human security. While ethyl acetate is a common industrial chemical with many legitimate uses, its potential for misuse in warfare cannot be ignored. By strengthening regulations, enhancing monitoring, and promoting awareness, we can work to prevent the devastating impact of ethyl acetate weapons and uphold the principles of international humanitarian law.
