1. Storage tanks, pipelines, and related equipment for anhydrous isopropanol can be made of carbon steel, but measures should be taken to prevent water vapor. Isopropanol containing water must be stored in containers or equipment with appropriate lining or made of stainless steel to prevent corrosion. The pump for handling isopropanol is preferably an automatically controlled centrifugal pump and equipped with an explosion-proof motor. Transportation can be done using car tank trucks, train tank trucks, 200l (53usgal) iron drums, or smaller containers. The outer wall of the transport container should have markings indicating flammable liquids.

2. Storage precautions: Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. The storage temperature should not exceed 37 ℃. Keep the container sealed. It should be stored separately from oxidants, acids, halogens, etc., and avoid mixing storage. Adopt explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are prone to generating sparks. The storage area should be equipped with emergency response equipment for leaks and suitable containment materials.

1. Odor similar to ethanol. It is miscible with water, ethanol, ether, and chloroform. It can melt various organic substances such as alkaloids and rubber, as well as certain inorganic substances. At room temperature, it can ignite and burn, and its steam can easily form explosive mixtures when mixed with air.

2. This product has low toxicity, and operators should wear protective equipment. Isopropanol is prone to produce peroxides and sometimes requires identification before use. The method is to take 0.5mL of isopropanol, add 1mL of 10% potassium iodide solution, 0.5mL of 1:5 dilute hydrochloric acid, and a few drops of starch solution, shake for 1 minute. If it turns blue or blue black, it indicates the presence of peroxide.

3. Flammable and low toxic substances. The toxicity of steam is twice that of ethanol, while the toxicity when taken orally is the opposite. High concentration steam has a significant anesthetic effect, stimulates the mucous membranes of the eyes and respiratory tract, and can damage the retina and optic nerve. Rat oral LD505.47g/kg. The maximum allowable concentration in the air is 980mg/m3. Operators should wear gas masks. When the concentration is high, airtight protective goggles should be worn. Closed equipment and pipelines; Implement partial or comprehensive ventilation.

4. Belongs to the category of micro toxins. The physiological effects are similar to ethanol, with stronger toxicity, anestheticity, and irritation to the upper respiratory mucosa than ethanol, but not as strong as propanol. Almost no accumulation in the body, with a bactericidal ability twice as strong as ethanol. The olfactory threshold concentration is 1.1mg/m3. The maximum allowable concentration in the workplace is 1020mg/m3.
