They also include blood, spit, urine, animal waste, decaying plants and even insect bitesoshaeducationcenter.com. You can get infections or allergies by touching or breathing these hazardsoshaeducationcenter.com.

Types of biological hazards

OSHA groups biohazards into a few simple typesoshaeducationcenter.com. The table below lists them with examples and a quick safety tip.

Type	Examples	Safety tip
Germs	Bacteria, viruses, parasites and molds. oshaeducationcenter.com	Wear gloves and masks and wash your hands
Toxins	Natural poisons like botulinum toxin. oshaeducationcenter.com	Avoid contact and use special containers
Blood & sharps	Used needles, scalpels, blood, saliva and vomit. oshaeducationcenter.com	Throw sharps into hard containers and do not recap needles. cdc.gov
Animal & plant waste	Animal droppings, sewage and rotten plants. oshaeducationcenter.com	Wear gloves and masks and work in fresh air
Insects	Bees, mosquitoes and ticks. oshaeducationcenter.com	Use bug spray and cover exposed skin

How infection spreads?

Germs spread in a chain. Six links must line up. oshaeducationcenter.com:

1. Agent: the germ itself.
2. Reservoir: where the germ lives, like blood or a surface.
3. Exit: how it leaves the reservoir, like a cough or cut.
4. Transmission: how it travels, for example by touch or through the air. oshaeducationcenter.com
5. Entry: how it gets into a new person, like through broken skin or breathing. oshaeducationcenter.com.
6. Host: someone who can get sick. oshaeducationcenter.com.

If you break one link, the chain stops. Washing your hands, wearing gloves, cleaning surfaces or getting vaccinated are all ways to break links.

Reading biohazard symbols and signs:

An engineer named Charles Baldwin designed it in 1966 so people all over the world could recognize it. medxwaste.com You will see this symbol on bags, doors, and containers that hold dangerous biological material. medxwaste.com Its job is to warn you to use care. medxwaste.com

OSHA’s Bloodborne Pathogens Standard says you must put this label on any container that holds blood or other infectious waste. researchsafety.gwu.edu Lab doors also need a biohazard warning sign. The sign lists the germs inside, what safety gear to wear and who to call in an urgent situation. researchsafety.gwu.edu Labs that work with infectious agents from Levels 1 through 3 must post this sign. researchsafety.gwu.edu

How to handle and throw away biohazards:

Handle dangerous waste the right way. waste the right way. The CDC says most lab waste is no more risky than regular trash. But sharps and cultures can be dangerous. cdc.gov

Follow these steps:

• Label and store safely. Keep waste in a sealed, labelled container in a place with good air flow. Do not let it pile up. cdc.gov
• Treat before disposal. Sterilize waste with heat (autoclaving), chemicals or special machines before throwing it away. cdc.gov
  • Many sharps and cultures need to be sterilized on site. cdc.gov
• Follow the law. Local and national rules explain how to handle each type of waste. cdc.gov
  • Make a waste plan and train your team!
