Which is more harmful methanol or ethanol?
Methanol is much more toxic than its close cousin ethanol and is a great example of how differences in the way our bodies handle different chemicals has an influence on both the nature and the extent of toxic effects.
What is the antidote for methanol?
Fomepizole and ethanol are effective antidotes against methanol toxicity. Fomepizole or ethanol should be administered as soon as possible once the patient/victim has been admitted to a medical care facility.
Can you use methanol for cleaning?

Apricot brandies have been found to contain up to 10 810 mg, plum brandies, up to 8850 mg, and cherry brandies, up to 5290 mg methanol/1 pure alcohol. Cognac and grape brandies contain 103–835 mg/l and Scotch whisky 80–260 mg/l methanol (Nykänen & Suomalainen, 1983).
What does methanol smell like?
Methanol appears as a colorless fairly volatile liquid with a faintly sweet pungent odor like that of ethyl alcohol. Completely mixes with water. The vapors are slightly heavier than air and may travel some distance to a source of ignition and flash back.
What PPE is needed for methanol?
The level of risk of exposure to methanol will dictate the appropriate level of personal protective equipment required. At a minimum, safety glasses with side shields or safety goggles and task- appropriate gloves are recommended. Depending on the situation, additional personal protective equipment may be required.
How long does methanol stay in your system?
Once alcohol dehydrogenase is inhibited, clearance of methanol is prolonged from approximately 8.5 mg/dL per hour to an effective half-life of 45 to 90 hours.
What are the side effects of menthol on skin?
Redness, warmth, or irritation at the application site may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly. If your doctor has directed you to use this medication, remember that your doctor has judged that the benefit to you is greater than the risk of side effects.

How do you counteract menthol on your skin?
Menthol can cause a cold or burning sensation, which is usually mild and should lessen over time with continued use. If this sensation causes significant discomfort, wash the skin with soap and water.

How do you use methanol safely?
Use in a chemical fume hood. Wash hands before breaks and immediately after handling the product.Avoid contact with skin, eyes, and clothing.Take precautions against static discharge. Conditions for safe storage, including any incompatibilities: Store in a cool location.
Is methanol irritant or harmful?
Methanol may be absorbed across the skin and can result in systemic toxicity. Methanol is also irritating to skin and may cause dry skin and redness [14]. Percutaneous absorption has been noted to cause toxicity in children.

Methanol intoxication (even in small amounts) is very dangerous because it can cause severe visual dysfunction (including irreversible bilateral blindness), metabolic disturbances, permanent neurological dysfunction and even death [1].
What is methanol used for?
Methanol and its derivative products such as ascetic acid and formaldehyde created via chemical reactions are used as base materials in acrylic plastic; synthetic fabrics and fibers used to make clothing; adhesives, paint, and plywood used in construction; and as a chemical agent in pharmaceuticals and agrichemicals.
