MEA Triazine 78% Safety Data Sheet (SDS) — Hazards, Handling & Compliance

MEA Triazine 78% is classified under the Globally Harmonized System (GHS) as: Skin irritation — Category 2 (H315: Causes skin irritation) Serious eye damage — Category 1 (H318: Causes serious eye damage) Specific target organ toxicity, single exposure — Category 3 (H335: May cause respiratory irritation) The product contains residual free formaldehyde (typically < 1%). Formaldehyde is classified as a suspected carcinogen (Category 1B) and skin sensitiser. Exposure to formaldehyde vapour should be minimised through proper ventilation and PPE use. Signal word: DANGER Hazard statements: H315, H318, H335 Precautionary statements: P261, P264, P271, P280, P302+P352, P305+P351+P338, P332+P313, P337+P313, P362+P364

Inhalation: Move the person to fresh air. If breathing is difficult, provide oxygen. If respiratory irritation persists, seek medical attention. Skin contact: Remove contaminated clothing immediately. Wash affected skin with plenty of water and mild soap for at least 15 minutes. If irritation develops or persists, seek medical attention. Eye contact: Rinse cautiously with water for at least 15 minutes. Remove contact lenses if present and easy to do. Continue rinsing. Seek immediate medical attention — MEA Triazine can cause serious eye damage. Ingestion: Rinse mouth with water. Do not induce vomiting. Seek medical attention immediately. Provide the SDS to medical personnel.

Handling: Use only in well-ventilated areas or with local exhaust ventilation. Avoid breathing vapours or mist. Wear appropriate PPE (chemical splash goggles, nitrile gloves, chemical-resistant clothing). Avoid contact with skin and eyes. Wash hands thoroughly after handling. Storage: Store in original sealed containers in a cool, dry, well-ventilated area. Keep away from direct sunlight and heat sources (recommended 10–35 °C). Keep containers tightly closed when not in use. Do not store with strong oxidisers or acids. Ensure secondary containment is in place to manage potential spills. Incompatible materials: Strong acids, strong oxidisers, copper, brass, aluminium, and zinc.

Occupational exposure limits: Formaldehyde (residual): OSHA PEL 0.75 ppm (TWA), 2 ppm (STEL) MEA Triazine: No specific OEL established — apply good industrial hygiene practice Engineering controls: Use local exhaust ventilation at mixing and injection points. Enclosed systems are preferred for continuous dosing operations. Ensure adequate general ventilation in storage and handling areas. Personal protective equipment: Eye protection — Chemical splash goggles or full-face shield Hand protection — Nitrile or neoprene chemical-resistant gloves Body protection — Chemical-resistant clothing or coveralls Respiratory protection — If ventilation is insufficient, use an organic vapour respirator (e.g. half-face with formaldehyde cartridge)

UN Number: Not classified as dangerous goods for transport under standard conditions. Some jurisdictions may classify based on formaldehyde content — check local regulations. REACH: The substance is pre-registered under REACH (EC 1907/2006). TSCA: Listed on the US Toxic Substances Control Act Inventory. DSL: Listed on the Canadian Domestic Substances List. Export documentation: Vasudev Chemo Pharma provides all required export safety documentation including GHS-compliant SDS in the language of the destination country, dangerous goods declarations where required, and customs classification support. Waste disposal: Spent MEA Triazine solution (containing dithiazine reaction products) is generally non-hazardous and can be disposed of through standard industrial wastewater treatment. Check local regulations for specific disposal requirements.
