Sodium hydroxide can cause damage to the respiratory tract as well as the eyes and other parts of the body if you smell it too much.

Sodium hydroxide is strongly irritating and corrosive. Dust or fumes can irritate the eyes and respiratory tract, corrode the nasal septum, burns can be caused by direct contact between the skin and eyes and NaOH, and accidental ingestion can cause burns in the digestive tract, mucous membrane erosion, hemorrhage and shock. It may produce harmful toxic fumes if decomposed.

Sodium hydroxide requires an isolated spill contaminated area with warning signs around it. Emergency personnel are advised to wear gas masks and chemical protective clothing. Do not come into direct contact with the spill; collect it in a dry, clean, covered container with a clean shovel, add a small amount of NaOH to a large amount of water, adjust to neutral, and place in the wastewater system.

Also rinse with plenty of water and place diluted wash water into the wastewater system. If a large number of leaks, collect and recycle or dispose of harmlessly and then discard.

Sodium hydroxide protective measures:

1, respiratory protection: wear an anti-virus mask if necessary.

2, eye protection: wear chemical safety glasses. Protective clothing: wear overalls (made of anticorrosive materials). Use with care and beware of spills into clothing, mouth and nose.

3. Hand protection: wear rubber gloves.

4. Other: After work, shower and change clothes. Pay attention to personal hygiene.

Extended information

Sodium hydroxide first aid measures:

1, skin contact: first, rinse with water for at least 15 minutes (dilute solution) / dry with a cloth (concentrated solution). Then rinse with 5-10% magnesium sulfate or 3% boric acid solution and consult a physician.

2. EYE CONTACT: Immediately lift eyelids and flush with running water or saline for at least 15 minutes. Or rinse with 3% boric acid solution (or dilute acetic acid). Seek medical advice.

3. Inhalation: Remove quickly from the scene to fresh air. Perform artificial respiration if necessary. Seek medical attention.

4. Ingestion: If a small amount of food is accidentally ingested, immediately neutralize with vinegar, 3-5% acetic acid or 5% dilute hydrochloric acid, large quantities of orange or lemon juice, drink egg white, milk or vegetable oil, seek medical advice promptly, and prohibit vomiting and gastric lavage.
