Study Notes

Laboratory Conduct and Safety

Properly cover up with protective dress to avoid exposing skin, and wear lab coats, gloves, goggles, and earplugs as necessary.
Wear comfortable clothing and keep long hair packed.
Keep bags, umbrellas, and other possessions away from laboratory benches.

Preparing for Eventualities

Know and follow laboratory rules and organization.
Be aware of potential hazards in the lab.
Know the location of safety equipment and facilities, such as eye wash, shower, fire extinguisher, and fire blanket.
Be prepared to lend a hand in case of emergencies.

Following Laboratory Rules

Maintain a clean and functional laboratory by cleaning up spills, recalibrating equipment, and reporting breakages.
Follow rules for labeling and handling chemicals and reagents.
Use bio resources ethically and dispose of used materials in respective waste disposal systems.
Follow safety procedures for using flames, radiation, noisy equipment, and volatile substances.

Avoiding Contamination

Avoid contaminating surfaces, compartments, utensils, equipment, supplies, buffers, and liquids and solutions.

Follow agreed procedures for sharing supplies and equipment.
Label items well, clean and restore them after use, and return them to their place.
Keep equipment in top form and maintain user-friendly conditions.

Working with Others

Practice effective communication, punctuality, and timing.
Understand and fulfill your role, and ensure your own competence and reliability.

Share knowledge, know-how, skills, and techniques.
Share facilities, rules, and instructions, and maintain scientific and professional news and announcements.

Ethical Principles

Prioritize safety, cordiality, facilitation, efficiency, and productivity.
Practice surveillance, avoid harm to self, others, property, and the environment.

Animal Ethics

Animals have intrinsic value and should be treated with respect.
Animals are sentient creatures with the capacity to feel pain, and their interests should be considered.

Five Domains of Animal Welfare

Nutrition: ensure access to sufficient, balanced, varied, and clean food and water.
Environment: provide comfort through temperature, substrate, space, air, odor, noise, and predictability.
Health: maintain good health through the absence of disease, injury, and impairment.
Behaviour: provide varied, novel, and engaging environmental challenges.
Mental State: ensure positive states, such as pleasure, comfort, or vitality, and reduce negative states.

The Three Rs

Replace: use non-animal experimentation when possible.
Reduce: minimize the use of animals to obtain reliable data.
Refine: avoid hurting and suffering the animal, and minimize pain, suffering, distress, and lasting harm.

The Researcher Using Animals

Researchers should be trained in the biology of the animal species and know how to take care of the animals.
Researchers should be aware of the risks of microbial infectious agents, biological materials, and biologically derived toxins.

Biosafety

Biosafety involves effective policies, risk identification, assessment, and continuous monitoring, training, and cooperation.
Biosafety levels (BSL-1, BSL-2, BSL-3, and BSL-4) ensure different levels of protection when working with virulent microbial strains.
BSL-1 involves basic teaching or research laboratory work with non-pathogenic strains.

Laboratory Waste Management

Dispose of biological waste, regulated medical waste, and radioactive waste according to appropriate manuals and instructions.
Use special waste containers (bins, boxes) for biological waste, regulated medical waste, and radioactive waste.
Remove tops from bottles before disposal and ensure no detectable smell of chemicals from any bottle placed in the bin.
