Hazard Class: Acute Toxicity (oral, dermal, inhalation), Eye Irritation, Skin Sensitization
Signal Word: Warning
Hazard Statements: Harmful if swallowed; may cause skin irritation and sensitization; irritates eyes; toxic to aquatic life with long-lasting effects
Pictograms: Exclamation mark, Environment
Routes of Exposure: Skin contact, inhalation, ingestion, eye contact
Symptoms: Tingling or numbness (skin), eye redness, respiratory discomfort, nausea, vomiting, muscle twitching in severe cases
Chronic Effects: Prolonged or repeated exposure may aggravate pre-existing neurological, hepatic, or dermal conditions
Active Ingredient: Deltamethrin
Chemical Concentration: Typically ranges from 2.5% to 25% depending on formulation (dust, emulsifiable concentrates, wettable powders)
Other Ingredients: Surfactants, emulsifiers, solvents such as xylene, carrier oils, stabilizers (proprietary, composition varies by product)
Impurities: Expected to be below 1% total mass; no known regulated impurities above internationally accepted thresholds for pesticide formulations.
Inhalation: Move patient to fresh air, monitor for difficulty in breathing, provide artificial respiration if needed, seek medical attention for persistent symptoms
Skin Contact: Remove contaminated clothing, rinse skin thoroughly with soap and water, monitor for persistent irritation or rashes, seek medical attention if symptoms persist
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek prompt medical advice for continued pain or vision changes
Ingestion: Do not induce vomiting, rinse mouth, never give anything by mouth if the person is unconscious, get immediate medical help
Special Notes for Physicians: No specific antidote; treat symptomatically and support patient’s vital functions where required.
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam, water spray (avoid high pressure jets to prevent dispersal)
Hazardous Combustion Products: Emits toxic fumes including carbon monoxide, carbon dioxide, hydrogen bromide, and nitrogen oxides under fire conditions
Protective Equipment: Self-contained breathing apparatus and full firefighting gear to limit exposure to hazardous vapor and smoke
Fire and Explosion Hazards: Deltamethrin is not highly flammable but formulations containing solvents may burn; runoff from fire control can cause pollution
Precautions: Remove containers from the area if safe, cool exposed containers with water spray, contain fire fighting water to prevent environmental contamination.
Personal Precautions: Avoid inhalation or direct contact, ventilate the area, use suitable protective clothing, gloves, and goggles
Environmental Precautions: Prevent release into drains, surface water, or soils; cover or dike spillage to limit contamination
Spill Clean-Up Methods: Absorb with inert, non-combustible material such as sand, earth, or diatomaceous earth; collect residues into labeled containers for disposal
Decontamination: Wash spill area with plenty of water and detergent, collect cleaning waters, do not allow to enter sewers or waterways
Reporting: Notify local authorities if significant quantities escape or cause environmental damage.
Handling Precautions: Avoid contact with skin, eyes, and clothing; do not breathe vapors or mist; wash hands thoroughly after handling; do not eat, drink, or smoke when using product
Storage Requirements: Store in original containers, tightly closed, in a cool, dry, well-ventilated area away from direct sunlight, heat sources, and incompatible substances such as strong acids or oxidizers
Incompatibilities: Avoid storage near food, beverages, animal feed, and pharmaceuticals
Special Handling Practices: Use with proper engineering controls and personal protective equipment; do not reuse empty containers; clearly label storage area as hazardous pesticide material.
Occupational Exposure Limits: No established occupational exposure limit for Deltamethrin; general values for pyrethroids and solvent carriers may apply
Engineering Controls: Use local exhaust ventilation or fume hoods to minimize airborne concentrations
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles or face shield, long-sleeved workwear, suitable respiratory protection for inadequate ventilation or during cleaning of spillages
Hygiene Measures: Remove contaminated clothing and wash before reuse, avoid overexposure, provide washing facilities at the worksite.
Appearance: White to off-white crystalline powder in pure form, clear to slightly hazy liquids in formulations
Odor: Mild, faintly chemical or aromatic if formulated with solvents
Melting Point: 98°C
Boiling Point: Decomposes before boiling
Vapor Pressure: Very low, less than 1 x 10-7 mm Hg at 20°C
Solubility: Insoluble in water, soluble in organic solvents like acetone and xylene
Density: Approximately 1.5 g/cm3
Partition Coefficient (Log Kow): ~4.6–6.2
pH: Neutral in water.
Chemical Stability: Stable under recommended storage and handling conditions; sensitive to extreme heat and sunlight
Incompatible Materials: Strong acids, bases, oxidizing agents
Hazardous Decomposition: Thermal breakdown produces toxic gases such as bromine compounds, NOx, CO2, and CO
Polymerization: Not likely to occur under normal usage conditions.
Acute Toxicity: Oral LD50 in rats 31–128 mg/kg; dermal and inhalation toxicity lower; more toxic for cats and aquatic life
Chronic Effects: Prolonged exposure may cause skin sensation or allergic reactions, rare liver damage in laboratory animals, no conclusive evidence of carcinogenicity
Symptoms of Exposure: Numbness, tingling, convulsions at extremely high doses, nausea, vomiting, incoordination
Mutagenicity/Teratogenicity: Negative in most tested systems for mutagenicity, teratogenicity, or reproductive toxicity
Sensitization: May cause skin sensitization on repeated contact.
Ecotoxicity: Highly toxic to aquatic organisms such as fish (LC50 for rainbow trout <0.1 μg/L), invertebrates, and bees; low toxicity to birds and mammals
Mobility: Strongly adsorbed to soil particles; limited leaching; surface run-off possible with improper handling
Persistence and Degradability: Moderate persistence; degradation half-life in soil ranges from 5–30 days depending on conditions
Bioaccumulation Potential: Potential to bioaccumulate in aquatic organisms due to high Log Kow; metabolic breakdown in most vertebrates limits retention
Other Adverse Effects: Dangerous for non-target beneficial insects and aquatic habitats near application sites.
Waste Disposal Methods: Dispose as hazardous chemical waste at approved facilities; do not dispose of into natural environment, drains, or watercourses
Container Disposal: Triple-rinse empty containers, puncture to prevent reuse, and dispose of in line with local pesticide container regulations
Contaminated Waste: Collect and label spilled or contaminated materials for specialized removal
Legal Compliance: Follow all local and national environmental waste legislation for pesticides.
