Safely Handling Sulfuric Acid: Risks, Best Practices, and Zipfluid Engineered Solutions
Sulfuric acid (H₂SO₄) is a mineral acid composed of sulfur, oxygen, and hydrogen.
It is a colorless, odorless, and viscous liquid, soluble in water.
The corrosivity of sulfuric acid solutions depends significantly on concentration and temperature.
Sulfuric acid is one of the most widely used chemicals in industry. Thanks to its high acidity and dehydrating capacity, it is employed in the production of a wide range of products.
In this article we will discover:
Sulfuric Acid: The Most Common Uses
The main uses of sulfuric acid are in the production of fertilizers.
It is also widely employed in the production of industrial chemicals, lead-acid batteries, polymers, synthetic fibers, synthetic detergents, dyes and pigments, explosives, and pharmaceutical products.
Is sulfuric acid dangerous to humans?
Sulfuric acid is highly dangerous to humans.
While it is vital in production and refining, it poses serious health and safety risks if handled improperly.
What happens in case of contact with sulfuric acid
Upon contact with the skin, sulfuric acid causes immediate chemical burns.
The acid reacts exothermically (releasing heat) with water, including the moisture present in the skin, thereby intensifying tissue damage.
Symptoms include severe pain, redness, blistering, and in the most serious cases, deep tissue destruction.
Immediate and thorough rinsing with plenty of water is essential.
What happens if you breathe sulfuric acid vapors
Inhalation of sulfuric acid mist or vapors can irritate the nose, throat, and lungs.
Short-term exposure may cause coughing, breathing difficulties, and sore throat.
Higher concentrations or prolonged exposure can lead to severe respiratory issues such as bronchitis, pulmonary edema, or chronic lung damage.
What happens when you blend sulfuric acid
Sulfuric acid is also highly reactive and dangerous in other ways.
It is a strong oxidizer and can react violently with water, releasing significant heat that may cause splashes or even explosions, especially in concentrated forms.
It is incompatible with many substances, including metals, organic materials, and certain chemicals such as chlorates, permanganates, and carbides, posing risks of fires, explosions, or release of toxic gases.
When heated, it emits highly toxic fumes.
Suggested Safety Protocols
Due to its hazards, strict safety protocols are essential.
This includes the use of appropriate personal protective equipment (PPE), ensuring proper ventilation, handling the acid only in designated areas, and having emergency procedures ready in case of spills or exposure.
In the event of exposure, immediate first aid is critical: rinse the eyes with water for at least 30 minutes, wash the skin thoroughly, and seek medical attention promptly.
How to handle safely sulfuric acid
