Invasion route: inhalation, ingestion and percutaneous absorption.
Health hazard: It can irritate eyes, nose, throat and mucous membrane. Long-term contact can cause dermatitis. This product is often mixed with 2- hexanone, which can strengthen the peripheral neuropathy caused by 2- hexanone, but no peripheral neuropathy was found when it was exposed to butanone alone.
Poisons can cause irritation, allergy, hypoxia, coma and anesthesia, systemic poisoning, carcinogenesis, teratogenicity, mutation and pneumoconiosis.
1. Stimulation: Many substances cause irritation to human body, and the common stimulation sites are skin, eyes and respiratory system.
2. Allergy: Skin allergy seems to be a symptom of dermatitis (rash or watery), and there is also respiratory allergy called occupational asthma.
3. Hypoxia (asphyxia): There are three symptoms: simple asphyxia, blood asphyxia and intracellular asphyxia.
(1) Simple suffocation is due to the replacement of the surrounding oxygen by inert gases (nitrogen, carbon dioxide, ethane, hydrogen, etc.). ), so that the oxygen content in the air is reduced, ranging from dizziness and nausea to coma and even death;
(2) Blood asphyxia affects the oxygen-carrying capacity of blood, such as carbon monoxide, which will drop seriously when the air content reaches 0.5%;
③ Intracellular asphyxia is a chemical poison, which directly affects the ability of cells to combine with oxygen. For example, hydrogen cyanide and hydrogen sulfide are typical substances that cause intracellular asphyxia.
4. Both coma and anesthesia lead to the inhibition of the central nervous system, and butanone rises in large quantities.
Touching can lead to coma and even death.
