Sodium Hypochlorite: These Are Its Health Effects

Sodium hypochlorite, commonly known as liquid chlorine, is a disinfectant widely used in swimming pools, drinking water, cleaning, and industry. However, its incorrect use or accidental exposure can have negative health consequences. In this article, we explain the risks, how to avoid them, and what to do in case of poisoning or burns.

Is sodium hypochlorite bad for your health?

When used properly and in controlled concentrations, sodium hypochlorite does not pose a danger to human health. In fact, it is key in the disinfection of drinking water and cleaning of surfaces.

However, direct, unprotected exposure, especially at high concentrations, can cause toxic effects in the body. The most common are skin, eye, and respiratory irritations. In more severe cases, it can cause chemical burns or poisoning.

What happens if you drink or swallow sodium hypochlorite?

Drinking sodium hypochlorite is extremely dangerous. Ingesting this product, even in small amounts, can cause:

• Severe irritation of the mouth, throat, and stomach
• Nausea, vomiting, and abdominal pain
• Serious internal injuries
• In extreme cases, breathing difficulty or loss of consciousness

If someone has accidentally swallowed sodium hypochlorite, it is recommended do not induce vomiting and seek urgent medical attention. Bringing the product container or label with you can help medical personnel act quickly.

Skin effects: sodium hypochlorite burns

Direct contact with the skin, especially if the product is concentrated, can cause chemical burns. The affected areas often become red, stinging, and in more severe cases, blisters or tissue destruction.

Treatment in case of contact:

1. Rinse with plenty of water for at least 15 minutes.
2. Do not apply ointments or creams without medical advice.
3. Consult a doctor if there is persistent pain or visible lesions

Can it be used on wounds?

Although some medical formulations of diluted hypochlorite are used under professional supervision for cleaning infected wounds, household or industrial sodium hypochlorite should never be used on broken skin.

Using it inappropriately on wounds can cause tissue damage, severe pain, and serious complications. For wound cleaning, use specific solutions prescribed by healthcare professionals.

Inhalation or prolonged exposure: what are the risks?

Inhaling sodium hypochlorite vapors (for example, when handling it without ventilation) can cause:

• Irritation of the nose and throat
• Coughing, difficulty breathing
• Headache and general malaise

In closed environments or in combination with other substances (such as acids or ammonia), it can release toxic gases, such as chlorine gas, which pose a serious health risk.

How does sodium hypochlorite poisoning occur?

Poisoning can occur due to:

• Accidental ingestion
• Mixing with other cleaning products
• Prolonged unprotected contact
• Poor ventilation during use

In these cases, common symptoms include: mucous membrane irritation, nausea, vomiting, abdominal pain, breathing difficulties, and external or internal burns.

Where can I find more technical information?
You can review professional sheets such as the “Safety Data Sheet (SDS)” which details all the effects of sodium hypochlorite in the event of poisoning or accident.

Prevention and safety measures

To avoid health risks, it is recommended:

• Read and follow the manufacturer’s instructions
• Do not mix with other products (such as vinegar or ammonia)
• Wear gloves, protective eyewear, and appropriate clothing
