| The following was taken from the Material Safety Data Sheet (MSDS) for the health hazards of nitromethane and methanol:
Nitromethane:
HEALTH HAZARD DATA
THRESHOLD LIMIT VALUE (PERMISSABLE EXPOSURE LIMIT): 100 ppm (TLV and PEL)
EFFECTS OF OVEREXPOSURE
Liquid: Prolonged exposure can lead to mild irritation due to "defatting". Only slightly toxic by ingestion.
Vapor: Headache, nausea, vomiting, narcosis. Chronic overexposure may cause liver and kidney damage.
FIRST AID
EYE: Nonirritating. Flush eyes with water for 15 minutes.
SKIN: Wash exposed skin with soap and water. Launder clothing wet with NM before reuse.
INHALATION: Remove to fresh air. Call a physician, who may check for increased methemoglobin content.
INGESTION: Induce vomiting by giving victim 2 glasses of water and having him place a finger down the throat.
Methanol
Synonyms: Methanol; Methyl alcohol ,CAS No.: 67-56-1, Molecular Weight: 32.04, Chemical Formula: CH3OH
Industrial Information
Hazards Identification
POISON! DANGER! VAPOR HARMFUL. MAY BE FATAL OR CAUSE BLINDNESS IFSWALLOWED. HARMFUL IF INHALED OR ABSORBED THROUGH SKIN. CANNOT BE MADE NONPOISONOUS. FLAMMABLE LIQUID AND VAPOR. CAUSES IRRITATION TO SKIN, EYES AND RESPIRATORY TRACT. AFFECTS THE CENTRAL NERVOUS SYSTEM, GASTROINTESTINAL TRACT AND LIVER.
NFPA Ratings: Health: 1 Flammability: 3 Reactivity: 0
Contact Rating: 1 - Slight
Potential Health Effects
Inhalation: A slight irritant to the mucous membranes. Toxic effects exerted upon nervous system, particularly the optic nerve. Once absorbed into the body, it is very slowly eliminated. Symptoms of overexposure may include headache, drowsiness, nausea, vomiting, blurred vision, blindness, coma, and death. A person may get better but then worse again up to 30 hours later.
Ingestion: Toxic. Symptoms parallel inhalation. Can intoxicate and cause blindness. Usual fatal dose: 100-125 milliliters.
Skin Contact: Methyl alcohol is a defatting agent and may cause skin to become dry and cracked. Skin absorption can occur; symptoms may parallel inhalation exposure.
Eye Contact: Irritant. Continued exposure may cause eye lesions.
Chronic Exposure: Marked impairment of vision and enlargement of the liver has been reported. Repeated or prolonged exposure may cause skin irritation.
Aggravation of Pre-existing Conditions: Persons with pre-existing skin disorders or eye problems or impaired liver or kidney function may be more susceptible to the effects of the substance.
For the full MSDS on these just do a web search on "MSDS and nitromethane" or "MSDS and methanol."
Hope this answers your question,
