Is methanol fire resistant?

This blog post will answer the question, “Is methanol fire-resistant” and cover topics like the fire-resistant properties of methanol and frequently asked questions related to the topic.

Is methanol fire resistant?

Methanol is not fire-resistant. It can catch fire easily.

Is methanol flammable?

Yes, it is flammable. In the presence of a flame or spark, methanol will burn readily at room temperature. It’s also a possible explosive threat if it’s aerosolized. Methanol has a flashpoint of 51.8 ℉ (11 Celsius).

What Is Methanol and How Does It Work?

Methanol is one of the most often utilized alcohols in industry, second only to ethanol, as we’ve previously said. It has the chemical formula CH3OH.

It is a result of bacterial processes on Earth, although it is found in minute amounts in humans and most other living species as a consequence of chemical synthesis.

Methanol is a fairly frequent substance in the regions of space where stars are forming across the whole cosmos.

Can methanol catch fire?

Yes, it can catch fire. Due to its extreme flammability, a methanol spirit burner may really be made using only a wick and a glass container.

Methanol vapors are heavier than air, thus they tend to gather in space at low levels and may travel quite a distance as well. In greater concentrations, methanol is not only combustible but also potentially explosive.

This implies that methanol must always be handled with care and kept away from open flames and any sparks in a well-ventilated area.

Can Methanol Be Burnt?

Yes, methanol burns quite cleanly, producing carbon dioxide and water as the end products (or possibly CO in the event of partial combustion).

What Class of Flammables is methanol?

Methanol may catch fire under almost any normal temperature circumstance since it is a class 3 (severe) flammable hazard.

It’s also vital to remember that a water-based extinguisher cannot be used to put out a methanol fire since the liquid nature of the substance makes it probable that water would splash over the flames and cause them to spread rather than go out.

Is Alcohol (Ethanol) More Flammable Than Methanol?

To begin, we presume that by “alcohol,” you mean ethanol, the type of alcohol that we consume and also utilize as a fuel?

This is a crucial difference since there are several alcohols (for example, the drug acetaminophen or paracetamol is alcohol but does not burn effectively).

If ethanol is what we’re referring to, then yes, methanol is more flammable than ethanol even if it contains less of it.

Methanol has a flashpoint of 51.8 degrees F (11 degrees Centigrade), whereas ethanol has a flashpoint of 57.2 ℉ (14 degrees Centigrade), indicating that methanol is more flammable.

Is Methanol Dangerous?

Yes. Not only is methanol hazardous, but it is also very toxic.

A person’s optic nerve may be destroyed in as little as 10 milliliters (about 1/3 of a US fluid ounce), leaving them blind.

A single fluid ounce has the ability to kill.

Unfortunately, methanol poisoning is rather prevalent. This is because ethanol and denatured alcohol have extremely similar smells and may easily be confused.

Is Methanol Blindness Curable?

Methanol blindness could be avoided if an antidote is administered as soon as poisoning symptoms appear.

The damage to the optic nerve, however, is permanent once it has been destroyed.

What Is The Methanol Antidote?

Surprisingly, ethanol works as a methanol antidote.

By consuming ethanol, one causes the liver to transition from breaking down methanol to breaking down ethanol, giving the liver a chance to recuperate. The liver breaks down the most complicated alcohols in the system first, followed by the simplest.

While the ethanol is doing its magic, a hospital should ideally also provide dialysis to eliminate the methanol from the blood.

Uses and Advantages of methanol

The uses and advantages of methanol are listed below:

  • Antifreeze
  • Solvent
  • Fuel
  • Food

I will now elaborate on the guidance given above.


Methanol possesses chemical features that enable it to reduce the freezing point and raise the boiling point of a water-based liquid. 

Methanol is utilized as an antifreeze in windscreen washer fluid because of these characteristics, which prevent the cleaning fluid from freezing. 

Additionally, it is injected into natural gas pipelines to reduce the freezing point of water during the transportation of oil and gas.


Methanol is largely utilized as a solvent in the manufacturing of inks, resins, adhesives, & dyes. Important medicinal chemicals and goods including cholesterol, vitamins, and hormones are also produced using it as a solvent.


Methanol is employed in energy-related applications to the tune of 45 percent of the world’s supply. Methanol is a form of fuel that may be used in cars or as boat fuel. 

Additionally, it may be used to create the effective fuel known as methyl tertiary butyl ether, which can generate fewer emissions than regular gasoline. 

Methanol is also a component of biodiesel, a sustainable fuel generated from plant or animal fats that may be mixed with conventional fuel.


Fruits and vegetables are among the numerous foods that naturally contain methanol. Human gene activity is regulated by dietary methanol. It’s also produced in the human digestive tract to aid in the digestion of meals.

When Methanol is burned, is it toxic?

The byproducts of burning methanol are water and carbon dioxide, neither of which are dangerous, even though methanol itself, both as a liquid and as a gas, is poisonous (though CO2 is a potential asphyxiation hazard).

Methanol: Can it be poured down the sink?

No, methanol must never be poured down the drain or flushed down the toilet, and it should be disposed of according to the directions on the material safety data sheet that came with it.

Dangers of Methanol

With powerful oxidants, methanol reacts strongly, posing a fire or explosion risk.

Risks of explosion of Methanol

  • Methanol vapor and air mixtures are explosive.
  • Agent poses a poison (toxic) & vapor explosion threat indoors, outside, or in sewers.
  • An explosive threat might result from a run-off to the sewers.
  • When heated, containers may explode.

Fire fighting information for methanol

  • Methanol: It is highly flammable.
  • Heat, flames, or sparks will readily ignite the agent.
  • Fire emits irritants, corrosive, and/or poisonous fumes.
  • Vapors might return to the point of ignition after traveling there.
  • Run-off into sewers might put people at risk for fire.

Warning: The agent’s flash point is very low. When battling flames, water spray may be ineffective.

How to extinguish methanol fire?

  • Use dry chemical, co2, water spray, or alcohol-resistant froth for minor flames.
  • Use water, fog, or alcohol-resistant froth to put out huge flames. If it is feasible to remove containers from the fire area without endangering others, do so. Use water mist or water spray instead of direct streams.
  • Use unmanned hose clamps or monitor nozzles to battle fires involving tanks or car/trailer loads, or fight the fire from as far away as possible. Cool containers by soaking them with water until the fire is completely extinguished. 

Withdraw away if you hear increasing noises coming from venting safety devices or see any tank discoloration. Never approach tanks that are on fire.

  • Use unmanned hose clamps or monitor nozzles for large fires; if this is not practicable, leave the area and let the fire burn.
  • Pollution may result from run-off from firefighting or diluting water.
  • Control run-off and dispose of it correctly if the circumstances permit (effluent).

What happens when methanol is ingested?

Methanol ingestion may have a variety of negative health consequences:

  • Neurological symptoms include headaches, vertigo, agitation, acute manic episodes, forgetfulness, a lowered degree of awareness, coma, and seizures.
  • Gastrointestinal symptoms include nausea, vomiting, anorexia, severe stomach pain, gastrointestinal bleeding, diarrhea, altered liver function, & pancreatic inflammation.
  • Ophthalmologic symptoms include visual disturbances, blurred vision, light sensitivity (photophobia), visual hallucinations, partial to complete vision loss, and very seldom, eye discomfort. An aberrant finding may be discovered via a visual examination. A strong methanol exposure is indicated by fixed dilated pupils.
  • Electrolyte imbalances, for example. Severe poisonings have been linked to renal failure, blood in the urine, and cellular muscle death. A high heart rate or a sluggish heart rate and an accelerated rate of breathing are common in fatal situations. When death is near, respiratory arrest and low blood pressure take place.

First Aid information on methanol

  • General information: The first course of therapy largely supports cardiovascular and respiratory health. Treatment aims to either stop methanol from turning into hazardous metabolites or to quickly eliminate those metabolites while addressing metabolic and fluid problems.
  • Antidote: Fomepizole and ethanol both work well as antidotes for methanol intoxication. As soon as the patient or victim is admitted to a medical institution, fomepizole or ethanol should be provided. 


  • Remove the victim from the source of exposure as soon as possible.
  • Wash your eyes vigorously for at least 15 mins with tepid water.
  • Seek emergency medical help right now.


  • Remove the patient from the source of exposure as soon as possible.
  • Make sure the patient’s or victim’s airway is clear.
  • Avoid inducing vomiting (emesis).
  • Seek emergency medical help right now.


  • Remove the patient from the source of exposure as soon as possible.
  • Analyze your pulse and breathing system.
  • Make sure the patient’s or victim’s airway is clear.
  • If you have dyspnea or shortness of breath, give yourself some oxygen.
  • As needed, assist with ventilation. Use a barrier or a bag-valve-mask device at all times.
  • Provide artificial respiration if breathing has stopped (apnea).
  • Seek emergency medical help right now.


  • Remove the patient from the source of exposure as soon as possible.
  • For information on patient/victim decontamination methods, see the Decontamination section.
  • Seek emergency medical help right now.

Frequently Asked Questions(FAQs), “Is methanol fire resistant?”

How easily can pure methanol ignite?

The flash point of methanol is quite low. This implies that even minute quantities of igniting material may start a fire. 

Because methanol is water-soluble, extinguishing methanol-caused flames with water may not be sufficient. Dry chemicals, alcohol-resistant froth, or co2 may be used to put out minor or large flames.

Is gasoline more flammable than methanol?

Methanol is less flammable than gasoline and has a decreased danger of ignition. Enhanced energy security: Methanol may be produced domestically from a number of carbon-based feedstocks including coal, biomass, and natural gas.

How can a methanol fire be put out?

Unlike gasoline, methanol fires can be put out with water, but a dry chemical fire extinguisher is far more effective. 

CO2 fire extinguishers (which are used to put out gasoline fires) don’t work as effectively since they blast things about as much as they remove oxygen from the fire.

Is it possible to pour methanol down the drain?

Never pour waste methanol or water that has been polluted with methanol into sewers or surface waterways.

Pouring methanol on the ground, into a body of water, or down the drain is not advised. Methanol must be appropriately disposed of since it is a dangerous substance.

At what temperature does methanol vaporize?

Methyl alcohol, usually known as methanol, is an organic solvent with low molecular weight and a low boiling point (64.7 °C, 148 °F). 

Methyl alcohol easily evaporates at room temp due to its low boiling point, and its fumes are constantly present. Both the vapor and liquid forms of methyl alcohol are very flammable.
