Chemical Name: Trioxane
Common Uses: Find it most in chemical manufacturing points, military fuel tablets, some plastics work. Folks sometimes recognize its camphor-like smell near onsite blends.
Synonyms: 1,3,5-Trioxane
Molecular Formula: C3H6O3
Appearance: Waxy white solid, can turn powdery or crystalline, tends to clump from moisture.
Odor: Gives off a faint formaldehyde scent.
CAS Number: 110-88-3
Main Risks: Flammable, releases toxic gases if burned. Irritates eyes and skin. Breathing dust or vapor may bother lungs or cause headaches.
GHS Classification: Flammable solid, acute oral toxicity, specific target organ toxicity.
Signal Word: Danger
Hazard Statements: May ignite under spark or flame, may harm internal organs if swallowed. Chronic exposure could harm the liver.
Routes of Exposure: Inhalation, ingestion, skin, eye.
Component: Trioxane
Concentration: Common batches run near 95-99% trioxane by weight.
Impurities: Usually traces of formaldehyde and water, sometimes less than 2% by mass. No significant stabilizers added in most industrial blends.
Contact with Eyes: Hold eyelids apart, flush with clean water at low pressure for at least fifteen minutes. Seek medical attention if redness or pain sticks around.
Skin Contact: Wash with plenty of soap and water. Remove tainted clothes promptly. If rash develops, call a clinician.
Inhalation: Move to fresh air. If cough, headache, or dizziness shows up, a doctor should review.
Swallowing: Rinse mouth. Never force vomiting. Follow up with a healthcare provider.
Extinguishing Media: Use foam, dry chemical powder, or clean water spray. Stay away from strong water jets; those might spread burning solid bits.
Specific Hazards: During fire, toxic fumes like formaldehyde and carbon monoxide can rise from broken-down trioxane.
Protective Methods: Wear self-contained breathing apparatus and flame-resistant gear.
Firefighting Advice: Keep containers cool, even if not burning. Stay upwind if fumes start rolling.
Personal Precautions: Mask up and glove up, especially if dust gets airborne. Ventilate area.
Response: Collect spilled material with spark-proof tools. Sweep gently, avoid scraping that builds static.
Environmental Care: Block entry into sewer or water runs.
Clean-up: Bag up waste. Wash spill site with water after finishing cleanup.
Handling: Keep far from open flame, hot work, or sparks. Ground staticky equipment. Avoid breathing dust.
Storage Conditions: Store in a cool, dry zone below 30°C, sealed tight, shaded from sunlight. Keep clear of oxidizers or strong acids.
Storage Containers: Use only containers approved for flammable solids.
Storage Life: Most lots hold stable for months if dry.
Engineering Controls: Run local exhaust fans for dusty work. Prefer closed work processes.
Personal Protection: Eyes: wear goggles. Skin: chemical-resistant gloves. Lung: respirator if powder gets kicked up.
Work Practice: Never eat, drink, or smoke near use. Wash hands after handling.
Exposure Limits: No official OSHA standard, but formaldehyde’s low-limit (0.75 ppm TWA) can guide.
Form: Crystalline solid
Color: White
Odor: Faint, sweet, formaldehyde-like
Melting Point: Falls around 61-62°C
Boiling Point: Near 114°C at normal pressure, but vaporizes easily before boiling
Solubility: Slightly soluble in water, mixes well with many organic solvents
Density: Roughly 1.17 g/cm³
Flash Point: Around 46°C (closed cup)
Explosion Limits: Dust-air blends may blow if ignited.
Chemical Stability: Holds together at room temperature, breaks down in strong acid or base.
Reactivity: Reacts hard with oxidizers, bleaches, or acids. Heats up quickly in wrong mixes.
Conditions to Avoid: Sparks, flames, humid air, acid spills.
Hazardous Products: Formaldehyde, carbon monoxide, and carbon dioxide can develop during fire or decomposition.
Polymerization: Unlikely under regular sealed storage.
Likely Effects: Irritates eyes, throat, and skin. Eating a moderate dose often means nausea or belly pain. Chronic exposure risks liver or kidney damage in tightly enclosed manufacturing spaces.
Acute Oral Toxicity: Animal studies suggest moderate risk—rats show harmful effects at several hundred mg/kg.
Carcinogenicity: Trioxane itself does not link directly to cancer in standard studies, but trace formaldehyde is a confirmed carcinogen.
Symptoms from Overexposure: Cough, headache, tiredness, burning skin or eyes.
Water Hazard: Trioxane dissolves slowly, does not bioaccumulate in big amounts but may lower water oxygen if dumped in bulk.
Aquatic Life Toxicity: High doses harm fish and small animals.
Persistence: Breaks down under sunlight and air, forming CO2 and water over weeks.
Bioaccumulation: Does not build up notably in plants or animals.
Mobility: Stays low in soil; moves more quickly in sandy or moist ground.
Preferred Disposal: Burn in licensed chemical incinerators with afterburners and scrubbers.
General Waste: Put non-reusable material in sealed, labeled drums for pickup.
Sewer Discharge: Never pour into runs or natural flows.
Container Waste: Empty packages should be cleaned or turned in for proper destruction.
UN Number: 3279 (self-reactive solid, type C, temperature controlled)
Hazard Class: Flammable solid
Labeling: Marked with flame hazard patch; use rigid closed containers.
Special Precautions: Keep transport cool, minimize bumps or rough handling, prevent static buildup.
International Lists: Registered under REACH in Europe, subject to TSCA inventory review in the United States.
Hazard Symbols: Flame icon, exclamation point for irritation
Other Controls: Employers handling more than minor amounts need written chemical safety plans and regular workplace air checks for formaldehyde. Local rules may set tougher guidelines.
