Nitric acid is a colorless, flammable, and highly corrosive liquid, widely used across multiple industries, such as:
- agriculture,
- electronics,
- metallurgy,
- chemical production.
As one of the most reactive and hazardous industrial chemicals, nitric acid requires rigorous safety protocols and specialized handling systems to ensure the protection of operators, the environment, and infrastructure.
What is nitric acid?
Nitric acid (HNO₃), historically also known as aqua fortis or spirit of nitre, is a powerful oxidizing agent and a mineral acid.
In its pure form, nitric acid is colorless, but over time it may develop a yellow or red tint due to decomposition into nitrogen oxides. It plays a crucial role in the production of ammonium nitrate (used in fertilizers), plastics, dyes, and explosives such as nitroglycerin and TNT.

Due to its highly corrosive and reactive nature, nitric acid is classified as a hazardous material under UN number 2031.
It can cause:
- severe skin burns,
- eye damage,
- respiratory injuries if inhaled or handled improperly.
Acute exposure can lead to chemical pneumonia, making the use of personal protective equipment (PPE) and the strict adherence to precise loading and unloading procedures essential.
Health and Environmental Hazards of Nitric Acid
The health and environmental risks arising from exposure to nitric acid are multiple. Let’s examine them:
- Skin contact can cause deep burns.
- Eye exposure may result in irreversible damage.
- Inhalation of vapors or mists can cause respiratory difficulties or death.
- Nitric acid vapors are toxic and can cause pulmonary edema in cases of significant exposure.
- Ingestion is extremely dangerous and can lead to internal burns and fatal aspiration.
- The substance reacts violently with reducing agents and organic materials, increasing the risk of fire or explosion.
- Decomposition by-products include nitrogen oxides (NOx), which are harmful to the environment.
