ETHANOL CANNOT BE DISPOSED OF DOWN THE DRAIN AT ANY CONCENTRATION. It must be collected and disposed of as hazardous waste.
P501 - Dispose of contents, container to a licensed hazardous-waste disposal contractor or collection site except for empty clean containers which can be disposed of as non- hazardous waste. First-aid measures after inhalation : Remove person to fresh air and keep comfortable for breathing.
Ethanol at a concentration of less than 24% can be disposed of in the sanitary sewer drain. Dilution of waste for disposal is illegal. less than 300 mg per liter.
This material is considered hazardous by the OSHA Hazard Communication Standard (29 CFR 1910.1200).
Ethanol: an ignitable/flammable chemical that meets the ignitability characteristic of hazardous waste as defined by EPA/DOE, thus must be collected for hazardous waste disposal. As a flammable liquid, it is also forbidden from entering the public sewer (even with copious amount of water).
Answer and Explanation: Ethanol dissolves in water to give molecules. It is a non-electrolyte that does not form ions in water. It simply dissolves due to H-bonding between the molecules of water and ethanol.
The alcohol dissolves in the water to form a homogenous solution, which cannot be distinguished anymore, so what you get is a homogeneous solution of water and alcohol.
Highly flammable. Gas/vapor flammable with air within explosion limits. INDIRECT FIRE HAZARD. May be ignited by sparks.
As a disinfectant, 70% concentration of alcohol is the most effective at killing pathogens.
Wrapped in paper or cloth and then heat-sealed bag w/ no more than 30 mL of free liquid or vials or rigid container in heat-sealed bag of no more than 30 mL free liquids. Placed in another plastic bag with absorbent. Finished bag placed in strong outer packagings with suitable cushioning.
Ideally, ethanol is lighter than water so it should float on the surface of the water but this is not the actual case. The ethanol in water neither sinks nor floats, rather it mixes thoroughly to form a homogenous solution. The reason for this mixing of two solutions is hydrogen bonding between the ethanol and water.
Don't pour or flush dangerous chemicals down your drains. Products such as paint, oils, lubricants, pesticides and thinners are not only terrible for the environment, they actually damage and corrode our pipes. Additionally, they can create fumes which are dangerous for our maintenance workers.
Chemicals that can be safely disposed down the drain include biological compounds and cellular constituents such as proteins, nucleic acids, carbohydrates, sugars, amino acids amines, nutrients, surfactants, and many metabolic intermediates.
Use rubbing alcohol, and let it evaporate before you put it all together. The evaporation process should take under one minute in optimal conditions.
70-75% ethanol is used for sterilization because it can dissolve microbial membranes. Ethanol has both a hydrophobic and hydrophilic portion which allows it to dissolve just about anything and this ability to dissolve organic molecules means it can strip away bacterial membranes which causes the cells to die.
70% denatured ethanol is not only less flammable but also offers a more economical price point for general wipe down and large-surface disinfection. Likewise, high-moisture alcohols evaporate slower and increase contact time without becoming immediately dry.
A 70% solution of alcohol takes more time in evaporation from the surface, increasing the contact time. Therefore, 70% isopropyl alcohol fulfills the both requirements. The 100% isopropyl alcohol coagulates the proteins instantly by creating a protein layer that protects the other proteins from further coagulation.
Alcohol should be stored in a tightly closed container in a cool, dry, well-ventilated area. Due to the chemical's extreme flammability, it must be kept away from all possible ignition sources, including heat, sparks and flames.
At a BAC of 200% to 400%, patients develop nausea and vomiting, hypothermia, dysarthria, amnesia, diplopia, and nystagmus. With a BAC of greater than 400%, patients can develop respiratory depression followed by coma and even death.
Flammability of the Product: Flammable. Auto-Ignition Temperature: 399°C (750.2°F) Flash Points: CLOSED CUP: 11.667°C (53°F) - 12.778 deg. C (55 deg. F) (TAG) Flammable Limits: LOWER: 2% UPPER: 12.7% Products of Combustion: These products are carbon oxides (CO, CO2).
Ethanol can conduct electricity, so electrocution hazards and possible ignition hazards are present during transloading operations. Human exposure to ethanol during spill situations could occur by inhalation, contact with the skin, or ingestion if ethanol reaches water supplies (surface water intakes or groundwater).
The estimated half-life of ethanol in the water range from 3 - 39 days, dependent upon the conditions.
(IV) Ethanol is completely evaporated; the small residual droplet is now composed only of water, which eventually evaporates in a few seconds.
