2. Isopropyl alcohol ***
3. Acetone
4. Chloroform.
What is isopropyl alcohol?
Isopropyl alcohol is a clear, colorless liquid that can be miscible with water, chloroform, ethanol, and ether among others. It has a strong odor and is somewhat combustible. Due to its high volatility, it evaporates quickly when exposed to air. Also known as isopropanol or IPA, it is a secondary alcohol and is used in a variety of applications such as disinfectants, disinfectants, disinfectants, and cleaners.
The newest hand sanitizer you must have
What is isopropyl alcohol used for?
Need something clean? Isopropanol has you covered. It often appears in many everyday household items such as rubbing alcohol, disinfectants, cleaners, and the latest must-have hand sanitizers. You'll also see it in window cleaners, antifreeze, and perfume.
It also has medicinal applications, such as as a cleaning agent, a major ingredient in rubbing alcohol, and an ingredient in antiseptic dressings.
As a solvent, IPA is useful for cleaning circuits and other electrical objects, as its ability to evaporate quickly means there is very little chance of shock or damage to electrical components.
Dangers of isopropyl alcohol
IPA is easily absorbed through the skin. But before you panic, remember that it is usually used in small amounts in personal care products, usually at a concentration of less than 70%, which means there is little chance of receiving toxic exposure to the substance.
However, if exposed to enough isopropyl alcohol, the resulting poisoning can affect a number of body systems, but mostly the nervous and respiratory systems. Acute exposure can cause a number of effects, including:
- headache,
- vomiting
- Dizziness,
- nausea,
- Loss of consciousness or coma.
- the death
- central nervous system (CNS) inhibition,
- low arterial pressure,
- Stomach ache,
- Slowed breathing and coughing.
Safety of isopropyl alcohol
If a person swallows isopropyl alcohol, it is best not to induce vomiting. Rinse his mouth with water and get medical attention as soon as possible.
If you get IPA on your skin, you should remove all contaminated clothing, shoes, and accessories. Do not re-wear your clothes until you can wash them thoroughly and make sure they are completely disinfected. Immediately rinse any affected areas of your body with plenty of water. If any symptoms persist, contact your doctor immediately.
Did you get isopropanol in your eyes? Flush them (including under the eyelids) with water for at least 15 minutes, then contact a medical professional.
If someone inhales an IPA, take them to the nearest source of fresh air, monitor their breathing, and keep them warm. If they are not breathing, and you qualify, CPR should be performed using a one-way valve or protective mask. Seek immediate medical attention for them.
On a related note, nothing should ever be administered orally to someone who has been exposed to isopropanol and is now unconscious.
Exposure controls/personal protection
Engineering controls: Emergency eyewash fountains and quick dunk areas should be available in the immediate area of potential exposure. Make sure there is adequate ventilation. Use local exhaust ventilation or a process enclosure to reduce the amount of acid in the air.
Personal protection: goggles, protective clothing, dust-proof gloves, an apron and a suitable mask or respirator during dusk. Wear leak-proof shoes. Do not wear contact lenses. For specifications on other PPE, follow the specific guidelines in your jurisdiction.
Safe handling of isopropyl alcohol
Make sure you have emergency eyewash fountains and quick-accessible dunking areas in the immediate area of potential IPA exposure.
You also need to make sure there is adequate ventilation - it's best to use local exhaust ventilation or a practical enclosure.
In terms of personal protective equipment, safety glasses, protective and anti-dust clothing, gloves, apron and a suitable mask or respirator during dusk are ideal. You should also wear impermeable shoes. And remember, wearing contact lenses while handling isopropyl alcohol is a no-go. Do not wear contact lenses. For specifications on other PPE, follow the specific guidelines in your jurisdiction.
