What health hazards does propionic acid pose?
A propionic acid solution poses multiple health risks. It can cause severe burns and redness of the skin, as well as permanent eye damage. Inhaling its vapours can irritate the nose, throat and lungs, leading to coughing, shortness of breath and breathing difficulties. Swallowing it can trigger pain, vomiting, diarrhoea and tissue damage, with possible perforation risks. Systemically, it may cause headaches, dizziness, fatigue and nausea.
What physical and chemical hazards exist with propionic acid solution?
Propionic acid solution is a flammable liquid and vapour. Its vapours are heavier than air and spread to ignition sources, forming explosive mixtures. It is corrosive to most metals and reacts to generate flammable hydrogen gas. It reacts violently with strong bases and oxidisers, creating fire or explosion risks. When heated, it decomposes, emitting acrid smoke and irritating carbon monoxide fumes.
What safety precautions apply to propionic acid?
Handling propionic acid solution requires strict precautions. Wear chemical-resistant gloves, eye protection (goggles or a face shield) and protective clothing. Use it in well-ventilated areas, outdoors, or with explosion-proof equipment. Keep it away from heat, sparks, flames and hot surfaces, and take anti-static measures. Store it in tightly sealed containers, away from incompatible substances. Ensure that eyewash stations and showers are readily available and do not induce vomiting if swallowed.
