Ammonia, a common household cleaner and industrial chemical, can be harmful to human health if not used properly. Here are some of the potential dangers and risks associated with exposure to ammonia:

1. **Respiratory Irritation**: Inhaling ammonia fumes can irritate the respiratory system, leading to symptoms such as coughing, shortness of breath, and throat irritation. Prolonged exposure to high concentrations of ammonia can cause damage to the lungs.

2. **Skin and Eye Irritation**: Contact with concentrated ammonia solutions can cause skin irritation, burns, and even blistering. If ammonia comes into contact with the eyes, it can cause severe irritation, redness, and in some cases, permanent damage to the cornea.

3. **Digestive Issues**: Swallowing ammonia can lead to nausea, vomiting, abdominal pain, and in severe cases, damage to the digestive tract. Ingesting large amounts of ammonia can be corrosive and toxic to internal organs.

4. **Allergic Reactions**: Some individuals may be allergic to ammonia and can experience allergic reactions upon exposure, such as skin rashes, hives, or respiratory distress.

5. **Long-Term Health Effects**: Chronic exposure to low levels of ammonia over time may contribute to respiratory problems, such as asthma or bronchitis. Long-term exposure to ammonia in the workplace has been linked to an increased risk of respiratory diseases and lung damage.

6. **Combustion Hazard**: Ammonia is flammable and can form explosive mixtures with air. If exposed to heat or flames, ammonia can ignite and cause fires or explosions.

7. **Toxicity**: Ingesting or inhaling large amounts of ammonia can be toxic and potentially life-threatening. Symptoms of ammonia poisoning include difficulty breathing, chest pain, confusion, and in severe cases, coma or death.

It is important to handle and use ammonia products with caution, following safety guidelines and using protective equipment such as gloves, goggles, and adequate ventilation. In case of accidental exposure or ingestion, seek medical attention immediately. Overall, while ammonia can be an effective cleaning agent, it is essential to be aware of its potential hazards and take necessary precautions to minimize risks to human health.
