What are the heath and safety hazards associated with H202 and H2SO4?
H2SO4 is a highly corrosive acid to metals, non-metals, and humans. H2O2, in low concentrations (3% to about 17%) is available commercially. It is used as a disinfectant and to dissolve dried blood that has accumulated on bandages.

Hydrogen peroxide (H2O2) and sulfuric acid (H2SO4) are both chemicals that can pose health and safety hazards if not handled properly. Here are some of the hazards associated with these substances:
1. Hydrogen Peroxide (H2O2):
- Irritant: Higher concentrations of hydrogen peroxide can be irritating to the skin, eyes, and respiratory system.
- Corrosive: Concentrated hydrogen peroxide can cause severe burns or tissue damage upon contact.
- Reactivity: Hydrogen peroxide is a strong oxidizing agent and can react violently with certain substances, such as flammable materials or incompatible chemicals.
2. Sulfuric Acid (H2SO4):
- Corrosive: Sulfuric acid is highly corrosive to metals, non-metals, and human tissues. It can cause severe burns and damage to the skin, eyes, respiratory system, and digestive tract.
- Toxic Fumes: When sulfuric acid comes into contact with water or moisture, it can release toxic fumes, such as sulfur dioxide, which can cause respiratory irritation or damage.
- Reactivity: Sulfuric acid is reactive and can cause strong exothermic reactions or explosions when mixed with certain chemicals, such as organic compounds or reducing agents.
To ensure safety when working with these chemicals, it is important to follow proper handling procedures and safety precautions. This includes wearing appropriate protective equipment (such as gloves, goggles, and a lab coat), working in a well-ventilated area, and having access to emergency eyewash stations and safety showers. It is also important to store these chemicals properly in a designated area, away from incompatible substances. Always consult the Material Safety Data Sheet (MSDS) for detailed information on hazards, handling, and first aid measures related to specific chemicals.
