Synergy can Disposal of Carbonyl Sulfide (COS)

Chemical Formula: COS
Description: Carbonyl sulfide is a colourless, flammable gas with an unpleasant odor resembling rotten eggs. It is the most abundant sulfur compound naturally present in the atmosphere.

Contents: The canister contains carbonyl sulfide (COS).
UN Number: 2204
- Purpose of UN Number: The United Nations number 2204 is used to identify carbonyl sulfide for transport and emergency response purposes.
Hazard Symbols:
- Flammable Gas Symbol: The label features a flammable hazard symbol indicating that carbonyl sulfide is highly flammable.
- Toxic Symbol: The label also includes a toxic hazard symbol (typically a skull and crossbones) indicating the substance's potential to cause serious health effects upon exposure.
Warning Information:
- Respiratory Protection: The label warns users to employ proper respiratory protection when handling the gas to avoid inhalation.
- Handling Instructions: Handle the gas with extreme care due to its flammable and toxic properties. Use in well-ventilated areas or within controlled environments with appropriate safety equipment.
- Emergency Procedures: The label may include first aid instructions in case of exposure, such as moving the affected individual to fresh air and seeking immediate medical attention.

Acute Exposure: Inhalation of carbonyl sulfide can cause respiratory tract irritation, headache, dizziness, nausea, and in severe cases, respiratory failure, and death.
Chronic Exposure: Long-term exposure can lead to central nervous system effects, liver, and kidney damage.
Skin and Eye Contact: Carbonyl sulfide can cause irritation and burns upon contact with skin and eyes.

Reactivity: Carbonyl sulfide can react with strong oxidizers and acids. It can decompose at high temperatures, producing toxic and corrosive byproducts such as sulfur dioxide (SO₂) and carbon monoxide (CO).
Incompatible Materials: Avoid contact with strong oxidizers, acids, and bases.

Atmospheric Presence: Carbonyl sulfide is naturally present in the atmosphere and can be released from natural sources such as volcanic emissions and biomass burning.
Toxicity to Wildlife: It is harmful to aquatic life and can cause long-term adverse effects in the aquatic environment.

Chemical Industry: Used as a chemical intermediate in the production of thiocarbamates and as a precursor to herbicides and insecticides.
Fumigation: Occasionally used for fumigating agricultural products and soil.

Storage: Store in a cool, dry, and well-ventilated place away from incompatible substances. Ensure storage areas are equipped with proper ventilation and spill containment systems.
Handling: Use appropriate leak detection methods and regularly inspect equipment. Handle with care to prevent leaks and spills. Use in areas with proper ventilation or within fume hoods.
Protective Equipment: Use personal protective equipment (PPE) such as respirators, gloves, eye protection, and flame-resistant clothing when handling carbonyl sulfide. Ensure that all personnel are trained in handling flammable and toxic gases and emergency response procedures.

Occupational Exposure Limits: Various regulatory bodies have established guidelines for safe exposure levels to prevent health risks.
Transport Regulations: When transporting carbonyl sulfide, it must be properly labeled and packaged according to international regulations, such as those set by the International Air Transport Association (IATA) and the International Maritime Organization (IMO).
