Common Name: Methanol
Chemical Formula: CH3OH
Synonyms: Methyl alcohol, wood alcohol
CAS Number: 67-56-1
Appearance: Clear, colorless liquid
Odor: Mild, slightly sweet, easily recognizable in the production plant
Recognitions such as these help every technician and logistics worker distinguish methanol from lookalike clear solvents that roll through an integrated chemical operation. The chemical formula and short list of synonyms ensure warehouse staff and blending operators in our facilities reach for the right drum, with no guesswork.
Main Dangers: Highly flammable liquid and vapor; Toxic through inhalation, skin absorption, ingestion
Acute Targets: Eyes, skin, respiratory tract, central nervous system
Chronic Targets: Liver, kidneys, optic nerves
Hazard Symbols: Flammable (Flame), Health Hazard (Skull and Crossbones)
Exposure limits exist for staff—showing how direct risks cannot be handled lightly, especially inside refining zones and loading terminals. We’ve seen, on more than one occasion, quick-reaction scenarios that stem from methanol’s unique toxicity profile, which is less forgiving even than some heavier alcohols.
Component: Methanol
Purity: Typically greater than 99% in bulk shipments
Impurities: Trace water, trace formaldehyde or formic acid, possible trace ethanol
No stabilizers or additives in our standard product lines
Our in-house lab tracks the ingredient profile with gas chromatography before every major shipment. Purity has always been a source of pride and operational necessity, because excess impurities can sabotage both downstream chemical synthesis and regular process safety, particularly when running catalytic reactions.
Eye Contact: Rinse immediately with plenty of water—seconds matter as methanol absorbs rapidly
Skin Contact: Wash thoroughly with soap and water; remove contaminated clothing
Inhalation: Move to fresh air without delay; give oxygen if breathing feels short
Ingestion: Do not induce vomiting; medical attention needed—methanol poisoning can progress quickly, and antidotes such as ethanol and fomepizole make the difference between recovery and tragedy
Our training drills reinforce that workers must always be ready to act: small mistakes can escalate when a substance interferes with the body so fundamentally.
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical powder, carbon dioxide
Incompatible Media: Water jets (risk of frothing and spreading)
Fire Hazards: Vapors heavier than air—can ignite at a distance; invisible flames present an extra hazard in daylight
Protective Gear: Self-contained breathing apparatus; full protective clothing
Our facilities are fitted with Class B suppression—and every shift cycles through fire-response training, because methanol fires burn fast, and vapor management is not just theory: it’s daily practice around our distillation columns and tank farms.
Spill Response: Eliminate ignition sources; ventilate area; contain spill using non-sparking tools and earth barriers
Personal Protection: Chemical-resistant gloves, goggles, flame-retardant clothing
Environmental Precautions: Prevent runoff to drains or water bodies
Cleanup: Absorb with inert materials; transfer to proper disposal drums
Every operator in the plant knows that a hole in a transfer hose or loading valve spells trouble. Rapid, organized response keeps spills from spreading—and years of experience underscore that every team member’s situational awareness is the real safeguard.
Storage: Keep in tightly closed, labeled drums or bulk tanks, away from oxidizers and heat sources; grounded lines and explosion-proof equipment standard
Handling: Minimize splashing and vapor; use engineering controls for transfers
Atmosphere: Inert gas blanketing in critical storage vessels reduces fire and health risks
Real operational reliability comes from routine maintenance, strict separation of incompatible materials, and that unbreakable culture of labeling and inspection—borne of lessons picked up over decades in chemical manufacturing.
Engineering Controls: Local exhaust hoods, explosion-proof equipment, continuous exposing monitoring in work areas
Personal Protective Equipment: Safety goggles, face shields, chemical-resistant gloves, flame-retardant lab coats, approved respirators where ventilation cannot guarantee safe air
Hygiene Practices: No smoking, eating, or drinking in handling zones; hand washing after handling
A manufacturer’s exposure controls never get left to chance—live monitoring, real-life fit-testing of respirators, and hard lessons from near-misses shape the house rules for every shift.
State: Liquid
Boiling Point: About 65°C (149°F)
Flash Point: About 12°C (54°F)
Vapor Pressure: Substantial at room temperature
Density: Around 0.79 g/cm3
Miscibility: Completely miscible with water
Odor Threshold: Detectable at low ppm
Our staff recognize the quick-evaporating nature of methanol—its low flash point and high volatility make closed handling the industry expectation, not a suggestion. This chemistry explains the process features built into every key node of our facility.
Stability: Stable under normal temperatures and dry, inert storage practices
Reactivity Alerts: Reacts with oxidizing agents, acids, some metals; forms explosive mixtures with air
Thermal Decomposition: Produces carbon monoxide, formaldehyde when burned or overheated
Over the years, plant staff have learned that ignoring compatibility charts brings unexpected maintenance headaches and process hazards. Precautions come from direct operational knowledge, reinforced by root-cause analysis after troubleshooting off-spec events.
Routes of Exposure: Inhalation, skin absorption, ingestion, eye contact
Acute Symptoms: Headache, nausea, dizziness, blurred vision, central nervous system depression
Chronic Effects: Blindness, liver and kidney damage, death in severe cases
Animal Toxicity Data: Documented LD50 (oral, rat) around 5,600 mg/kg
Years of accident reports and near-misses have drilled in just how quickly symptoms escalate. Field response depends on immediate recognition—not theoretical concern, but real vigilance on every production line and loading dock.
Environmental Fate: Biodegrades readily, but mobile in soil and water
Aquatic Toxicity: Toxic to aquatic organisms at higher concentrations
Bioaccumulation: Unlikely
The environmental team tracks releases with the same seriousness as worker safety. A controlled environment and regular training prevent accidental discharges, as the risk to waterways and organisms cannot be dismissed in modern chemical practice.
Methods: Dispose as hazardous waste in accordance with regulations; incineration or specialized facilities only
Do not pour into drains or soil
Used containers must be cleaned of residues before recycling or disposal
Disposal becomes a living reality for every operations team—where adherence to local laws means more than paperwork, and disciplined waste management flows from on-the-ground training, not only policy memos.
UN Number: 1230
Shipping Name: Methanol
Hazard Class: 3 (Flammable Liquid), Sub-risk 6.1 (Toxic)
Packaging Group: II (Medium Danger)
Placards and paperwork travel with every bulk load from our gates—our shipping crew lives the reality where overlooked documentation leads to chain-of-custody headaches and safety stopovers from port authorities.
Labelling: Flammable Liquid, Toxic by inhalation and absorption
Threshold Quantities: Subject to reporting and risk management under national chemical laws
Worker Protection: Covered under occupational exposure limits and hazardous chemical regulations
As regulations change, policy and practice must keep pace—years of audits and compliance reviews keep teams focused on the real-world impact of every new rule.
