Study Notes
Importance of Health and Safety
- Safety protocols are crucial to prevent accidents and ensure well-being in a laboratory environment.
- Regulations and standards ensure safe laboratory practices.
Risk Assesment
- Identify types of potential hazards in the laboratory environment:
- Chemical hazards: exposure to toxic chemicals, corrosive substances, flammable materials.
- Biological hazards: exposure to pathogenic microorganisms, viruses, bacteria.
- Physical hazards: sharp objects, high temperatures, electrical equipment.
- Radiation hazards: ionizing radiation, ultraviolet light.
- Fire and Explosion Hazards: flammable chemicals, faulty electrical equipment.
- Equipment Hazards: malfunctioning machinery, improper use of tools.
- Noise Hazards: loud equipment, machinery noise.
- Ergonomic Hazards: poorly designed workstations, repetitive tasks.
- Ventilation and Respiratory Hazards: poor air quality, exposure to fumes.
- Biomechanical Hazards: awkward postures, lifting heavy objects.
- Assess severity and likelihood of risks in the laboratory environment.
- Implement control measures to reduce identified risks.
Personal Protective Equipment (PPE)
- Minimum recommended PPE includes chemical resistant gloves, splash proof goggles, lab coat, face shield, and rubber apron when necessary.
- Correct procedures for donning and doffing PPE contribute to individual safety and overall laboratory well-being.
- Regularly inspect and maintain PPE to make sure it remains in good condition.
Emergency Procedures
- Familiarize yourself with evacuation protocols and assembly points in the laboratory.
- Understand basic first-aid measures for common laboratory injuries.
- Report accidents and incidents using a standardized incident report form.
Laboratory Equipment Safety
- Proper handling, usage, and regular maintenance of laboratory equipment are crucial to prevent accidents.
- Familiarize yourself with emergency shutdown procedures in case of equipment malfunction.
Chemical Safety
- Follow procedures for handling and storing chemicals.
- Material Safety Data Sheets (MSDS) should be available for all laboratory chemicals.
Toxic Effects of Chemical Exposure
- The effects of chemical exposure depend on various factors like dose, concentration, frequency, and duration of exposure.
- Local injuries involve the area of contact, typically caused by corrosive chemicals.
- Systemic injuries affect tissues or organs, occurring when toxins reach them through the bloodstream.
- Distinguish between acute and chronic chemical exposure and toxicity.
- Most toxicity estimates are derived from animal studies and may not directly correlate to humans.
- LD50 (lethal dose 50) is used to measure toxicity in animals.
Susceptibility to Toxic Substances
- Individual susceptibility to toxic substances varies based on factors such as:
- Nutritional habits, physical condition, obesity, medical conditions, drinking and smoking, and pregnancy.
