* Strong Odor and Irritant: Ammonia has a pungent, choking odor that can irritate the eyes, nose, and throat. Even low concentrations can cause discomfort and coughing.
* Respiratory Issues: Inhaling ammonia can cause respiratory problems, including shortness of breath, wheezing, and even pulmonary edema (fluid in the lungs).
* Skin and Eye Irritation: Contact with concentrated ammonia solutions can cause severe burns to the skin and eyes.
* Toxicity: Ammonia is toxic in high concentrations, potentially leading to serious health problems if inhaled or absorbed through the skin.
Fume hoods provide crucial protection:
* Ventilation: Fume hoods draw air away from the work area and exhaust it outside, preventing the buildup of hazardous ammonia vapors.
* Containment: The hood acts as a barrier, limiting exposure to ammonia in case of accidental spills or splashes.
Therefore, always work with concentrated ammonia solutions under a fume hood to protect yourself and others from the potential hazards.
