Study Notes

Biological Hazards

Biological hazards are biological substances that threaten living organisms (humans, animals, or the environment).
Sources include bacteria, viruses, fungi, parasites, prions, biological toxins, and other pathogenic microorganisms.
Exposure can cause infectious diseases, allergic reactions, or health problems.
Examples include human blood and blood products, carrying pathogens like HIV, Hepatitis B, and Hepatitis C.
Animal waste can contain bacteria, viruses, and parasites, posing a risk of diseases (e.g., Salmonella, E. coli).
Human bodily matter (blood, saliva, urine, mucus) can carry pathogens.
Microbiological waste from labs (cultures, stocks, or specimens) can contain high concentrations of pathogens.
Pathological waste (tissues, organs, body parts) may contain infectious agents.
Sharps waste (needles, scalpels, broken glass) can cause punctures or lacerations.

Chemical Hazards

Chemical hazards result from harmful chemicals causing adverse health effects, from minor irritations to severe diseases like cancer.
Chemicals exist as solids, liquids, or gases.
Examples in the workplace include corrosives (e.g., oven cleaners, caustic soda), explosives (e.g., nitroglycerin), toxic substances (e.g., lead, sodium cyanide), oxidizing agents (e.g., hair dyes, bleaches), flammable substances (e.g., LPG, methylated spirits), and materials hazardous to the environment (e.g., pesticides, mercury).
Molds and yeasts, types of fungi, can trigger allergic reactions when inhaled or touching skin (e.g., sneezing, coughing, itchy eyes, skin rashes).
Organic material (garbage, wastewater, sewage, plant materials, organic dust) can harbor microorganisms.
Airborne pathogens can be transmitted through the air (e.g., viruses, bacteria, other microbes). Stinging insects (bees, wasps) a hazard to those working outside.

Fire and Electrical Hazards

Fire hazards include substances that promote fire (flammable materials, open flames, messy areas), and electrical issues (faulty wiring, overloaded circuits).
Common materials like wood, paint, solvents, gasoline can easily ignite.
Welding/cutting equipment can create sparks.
Electrical equipment (defective tools, exposed wires, improper grounding) can lead to shocks, burns, or fires.
Improper storage of flammable materials near heat sources or in poorly ventilated areas heightens fire risk.
Lack of fire safety equipment and poor housekeeping increase fire risk.
