The following information (Health Effects, Handling/Disposal, and Ingredients) is taken from the product label and/or the Material Safety Data Sheet (MSDS) prepared by the manufacturer.

Health Effects
Enter text or highlight term...
Warnings: HARMFUL IF SWALLOWED OR ABSORBED THROUGH SKIN.
DO NOT BREATH VAPOR OR SPRAY MIST. AVOID CONTACT WITH EYES, SKIN OR CLOTHING. KEEP OUT OF REACH OF CHILDREN
Acute Health Effects: From MSDS
POTENTIAL HEALTH EFFECTS
EYES: This substance is not expected to cause prolonged or significant eye irritation.
SKIN: This substance is not expected to cause skin irritation and is only slightly toxic if absorbed through the skin. See Toxicological Information, section 11.
INGESTION: This substance is slightly toxic to internal organs if swallowed. The degree of injury will depend on the amount absorbed from the gut.
INHALATION: Breathing the vapor may be irritating to the respiratory tract. If inhaled, this substance is considered practically non-toxic to internal organs.
TARGET ORGANS: Diazinon is an inhibitor of the cholinesterase enzyme, found in nervous tissue, red blood cells, and plasma.
SENSITIZATION: This product contains trace quantities of methylisothiazolinone and methylchloroisothiazolinone as preservatives. At higher concentrations these preservatives have been shown to cause allergic skin reactions in susceptible individuals. These preservatives are also found in a number of widely used personal care products, such as shampoos and cosmetics.
COMMENTS HEALTH: Depending upon the extent and degree of overexposure to the product, signs and symptoms of cholinesterase inhibition can result following either ingestion, skin contact or inhalation routes of exposure. Signs and symptoms of cholinesterase inhibition can also result from either acute (one time), subchronic (repeated short-term) and chronic (daily life-time) exposure to the product.
Signs and symptoms of cholinesterase inhibition usually occur within 12 hours following overexposure. These effects may include, but may not be limited to, headache, dizziness, weakness, nausea, vomiting, diarrhea, constriction of the pupil of the eye, blurred or dark vision, excessive salivation or nasal discharge, profuse sweating and abdominal cramps. Incontinence, unconsciousness, convulsions and breathing difficulties are indicative of severe poisoning. In untreated severe poisoning, death is due to respiratory failure or cardiac arrest.
Chronic Health Effects: From MSDS

SENSITIZATION: No evidence of allergic skin reactions was observed in guinea pigs following repeated skin exposure.
NEUROTOXICITY: Diazinon is not considered to produce organophosphate induced delayed neuropathy. Results of chicken neurotoxicity studies were negative.
TERATOGENICITY: Diazinon is not considered to be a teratogen (a substance that causes birth defects). The rat and rabbit developmental NOEL's (no observable effect level) were 20 and 100 mg/kg/dy, respectively.
REPRODUCTIVE TOXIN: Diazinon is not considered to be a reproductive toxin. Results of a rat multigeneration reproduction study indicated that the daily dietary NOEL (No Observable Effect Level) for diazinon was 0.5 mg/kg/dy. The maternal maximum tolerated dose was 25 mg/kg/dy.
MUTAGENICITY: Diazinon is not considered to be a mutagen. Gene mutation studies involving chromosome aberrations (in vivo and in vitro), and DNA damage (unscheduled DNA synthesis in vitro and in vivo sister chromatid exchange).
Carcinogenicity: From MSDS
CARCINOGENICITY COMMENTS: Diazinon is not considered to be a carcinogen. NTP chronic feeding studies in rats and mice demonstrated no evidence of oncogenicity.
Rat no observable effect level (NOEL): 40 mg/kg/dy
Mice NOEL: aprox. 30 mg/kg/dy
A search of the EPA's Integrated Risk Information System (IRIS) found no evidence of human carcinogenicity.
First Aid: From MSDS

EYES: Flush eyes immediately with fresh water for at least 15 minutes while holding the eyelids open. Remove contact lenses if worn. No additional first aid should be necessary. However, if irritation persists, see a doctor.
SKIN: Remove contaminated clothing. Wash skin thoroughly with soap and water. See a doctor if any signs or symptoms described in this document occur. Discard contaminated non-waterproof shoes and boots. Wash contaminated clothing.
INGESTION: If swallowed, call a physician of Poison Control Center immediately. Drink 1 or 2 glasses of water and induce vomiting by touching the back of throat with a finger. Do not induce vomiting or give anything by mouth to an unconscious or convulsing person.
INHALATION: Move victim to fresh air. If not breathing, give artificial respiration, preferably mouth to mouth. Get medical attention.
NOTES TO PHYSICIAN: This material contains a cholinesterase inhibitor. Measurement of blood cholinesterase activity may be useful in monitoring exposure. If signs of cholinesterase inhibition appear, atropine sulfate is antidotal. 2-PAM (PROTOPAM) is also antidotal and may be used in conjunction with atropine but should not be used alone. This material contains light hydrocarbon liquid and an aspiration hazard may exist.
ADDITIONAL INFORMATION: In case of medical emergencies involving this product, call day or night, (800) 457-2022 OR (800) 454-2333.
