Study Notes
Importance of Protective Equipment
- The main purpose of using protective equipment like eye protection and a chemical suit is to prevent exposure to hazardous substances and minimize the risk of injury or harm.
Categories of Hazardous Substances
- Certain category of hazardous substances can cause liver damage.
Handling Reagent Chemicals
- Upon opening newly received reagent chemicals, it is essential to inspect the packaging and labels for any signs of damage or leakage.
Safe Handling of Chemicals
- Intentional smelling, inhaling, or tasting of chemicals should be avoided because it can lead to accidental ingestion, inhalation, or skin contact, which can be harmful.
Types of Hazards
- Corrosive substances are a type of hazard that can damage or destroy tissues and cells upon contact.
Chemical Ingestion
- Chemicals can enter the body through ingestion by accidentally drinking or eating contaminated substances or not washing hands before eating.
Personal Protective Equipment
- When working with acids, bases, or flammable materials, it is essential to wear protective equipment, including gloves, goggles, and a lab coat.
Forbidden Practices
- Eating, drinking, and smoking are forbidden in areas where hazardous chemicals are used or stored.
Emergency Procedures
- In the event of glassware breakage or chemical spills, immediate action should be taken to clean up the spill, dispose of the broken glassware, and notify the appropriate authorities.
Preventing Skin Contact
- Gloves should be used to prevent skin contact when handling hazardous materials.
Disposal of Chemicals
- Used solutions should be disposed of according to the recommended disposal procedures to prevent environmental contamination and minimize the risk of harm.
Calibrating Volumetric Glassware
- The purpose of calibrating volumetric glassware is to ensure accurate measurements and prevent errors in chemical analysis.
Role of Buret
