Name: N-Nitroso Diethylamine
Chemical formula: C4H10N2O
Appearance: Pale yellow, oily liquid with a faint, sweet odor
Common uses: Rarely used in industry due to high toxicity, found as an impurity in certain processes like pesticide manufacturing and some chemical syntheses
Other names: NDEA
Health hazards: Probable human carcinogen—linked to liver and other cancers in animal testing.
Acute toxicity: Highly toxic if swallowed, inhaled, or comes into contact with skin
Environmental hazards: Considerable risk to aquatic environments and persistent in soil run-off
Route of exposure: Inhalation, ingestion, skin absorption
Hazard symbols: Skull and crossbones, health hazard, aquatic toxicity
Chemical identity: N-Nitroso Diethylamine
Concentration: Pure or diluted in contaminated mixtures
Impurities: Sometimes found mixed with solvents or byproducts in industrial waste streams
Inhalation: Remove person to fresh air, check for breathing, call for medical help; exposure can quickly cause respiratory issues
Skin contact: Wash area thoroughly with soap and water, remove contaminated clothing, get medical advice
Eye contact: Rinse carefully under running water for at least 15 minutes
Ingestion: Do not induce vomiting, rinse mouth, seek immediate hospital care
Flammability: Burns readily, giving off toxic gases including nitrogen oxides
Suitable extinguishing agents: Foam, carbon dioxide, dry chemical
Firefighter protection: Full protective gear and self-contained breathing apparatus; run-off can pollute waterways
Combustion byproducts: Toxic fumes add to risk factors for fire crews and people nearby
Environmental precautions: Prevent spillage from reaching drains, sewers, or natural water bodies
Cleanup method: Absorb with inert material like sand, shovel into secure chemical containers, ventilate area
Personal protection: Chemical-resistant gloves, safety goggles, protective clothing, and respirator
Handling: Work in chemical fume hood, avoid breathing vapors, prevent skin and eye exposure
Storage: Locked, leak-proof containers, cool, well-ventilated area away from oxidizers or acids
Transport: Always in sealed, labelled, and tightly closed containers compliant with chemical transport laws
Engineering controls: Local exhaust ventilation, safety showers, eyewash stations nearby
Personal protection: Gloves, long sleeves, safety goggles, and a NIOSH-approved respirator when airborne levels risk exceeding safety limits
Exposure limits: No established OSHA or ACGIH exposure limits, but recommended values stay as low as reasonably achievable
State: Liquid
Color: Yellowish
Odor: Slightly sweet, noticeable at even low concentrations
Solubility: Moderately soluble in water, highly soluble in organic solvents
Boiling point: Around 177°C
Stability: Stable at room temperature, but light and heat speed up decomposition
Reactivity: Reacts with strong oxidizers, acids, and bases, releasing toxic nitrogen oxides
Incompatibles: Acids, oxidizers, reducing agents
Carcinogenicity: IARC lists as Group 2A—probably carcinogenic to humans, based on animal studies and mechanistic concerns
Acute effects: Irritation to mucous membranes, liver and kidney damage common in poisoning cases
Chronic effects: Long-term exposure multiplies cancer risk, especially in workplaces with poor ventilation or safety controls
Aquatic toxicity: Readily poisons fish and aquatic invertebrates even at low concentrations
Persistence: Doesn’t break down easily—threatens water supplies if not contained
Bioaccumulation: Builds up in organisms, entering the food chain
Waste handling: Treat as hazardous waste; specialized incineration only—never landfill or pour down the drain
Container disposal: Decontaminate through certified chemical waste services
Regulatory oversight: Disposal closely watched by local, state, and federal agencies
Classification: Toxic by inhalation and ingestion, needs tightly controlled packaging
Labeling: Prominent hazardous materials signage
Shipping: Permitted only through licensed carriers complying with hazardous material regulations; international shipments face extra scrutiny
Reporting requirements: Major environmental and workplace laws trigger mandatory reporting for spills, exposure, or improper storage
Chemical regulation: Covered under international treaties restricting trade and use; EPA, OSHA, and global agencies recognize its severe hazard status
Workplace restrictions: Strict limits on personnel access, mandatory record-keeping for use, storage, and disposal activities
