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.
