- Oil refining: It is utilized in the alkylation process to produce high-octane gasoline and other fuel products. It efficiently catalyzes the reaction of isobutane with butenes.

- Metal processing: It is used for dehydration and rust removing in metal industries. It converts iron oxides to soluble sulfate salts that can then be rinsed off.

- Battery production: Sulfuric acid is the electrolyte used in lead-acid batteries commonly found in vehicles. It helps convert chemical energy into electricity through redox reactions.

- Chemical manufacturing: It is used to produce chemicals like chlorosulfonic acid, alkyl and aryl sulfates, surfactants, dyes, and many other products used in various industries.

Health and Environmental Hazards

While sulfuric acid proves highly useful industrially, it also poses considerable risks if not handled properly. Some key hazards associated with it include:

- Corrosiveness: Being a strong acid, it causes severe burns upon contact with skin, eyes or tissues. Inhalation of vapors released during acid storage or usage can damage lungs and airways.

- Toxicity: In addition to burns, ingestion or inhalation of high concentrations of sulfuric acid can potentially be life-threatening due to toxicity. It may lead to internal organ damage.

- Reactivity: Sulfuric Acid vigorously reacts with water, producing a large amount of heat. It also reacts with combustible materials like organic compounds. Such reactions require cautious handling.

- Spills and leaks: Accidental spills while transporting or storing sulfuric acid in bulk quantities can contaminate soil and water resources if not contained and neutralized properly. This poses environmental hazards.

- Air pollution: Industrial processes using sulfuric acid as a catalyst or reactant result in emissions of sulfur dioxide gas, a regulated air pollutant. Stringent emission norms are mandated at production plants.

Regulations and Safety Precautions

Due to the health and safety risks posed by sulfuric acid, its production, transportation, usage and disposal are strictly regulated globally by agencies like the EPA in the United States. Key compliance measures include:

- Personnel safety training and use of proper protective equipment like acid-resistant clothing, gloves, goggles for all handling operations.

- Segregated storage in corrosion-resistant containers, berms, or enclosed areas. Leak detection and spill response systems are mandated.

- Transportation in DOT-approved containers meeting packaging guidelines for hazardous materials.

- Emission monitoring and air pollution control devices at industrial sites producing or utilizing sulfuric acid.

- Wastewater treatment of effluents to neutralize acidity before discharge. Proper disposal of solid wastes as hazardous materials.

- Community risk management plans near production facilities to handle potential emergency scenarios.

With the right preventive measures and compliant operations, society can benefit from this critical industrial chemical while minimizing related safety hazards. Strict adherence to safety protocols is a must given sulfuric acid's powerful yet precarious nature.
