What is a Class D - Poisonous and Infectious materials? Class D materials are those which can cause harm to your body. They are divided into three major divisions. Division 1: Materials Causing Immediate and Serious Toxic Effects. These are materials that are very poisonous and immediately dangerous to life and health.
Potentially infectious materials (PIMs) are bodily fluids that can spread infection from one person to another through direct contact. This lesson will cover which fluids might contain bloodborne pathogens and how they are transmitted between people.
Examples of biohazardous infectious materials include the AIDS/HIV virus, Hepatitis B and salmonella. The symbol for this division looks like three "c"s joined together with a little circle in the middle all inside a circle.
What are some biohazard examples?
- Human blood and blood products. This includes items that have been contaminated with blood and other body fluids or tissues that contain visible blood.
- Animal waste.
- Human body fluids.
- Microbiological wastes.
- Pathological waste.
- Sharps waste.
Types. Toxic waste products are divided into three general categories: chemical wastes, radioactive wastes, and medical wastes.
Biohazards are any material that can possibly contain infectious diseases. For example, human feces can contain diseases such as C. diff, Hepatitis A and E, Giardia, E coli, Cholera, and Norovirus so, yes, human feces are a biohazard.
Biohazard waste is sometimes referred to as medical waste, biomedical waste, or infectious waste. It includes bodily fluids such as urine, blood, vomit, feces, tissues, and organs. Medical supplies such as needles used for vaccines and equipment used for lab work are also considered types of biohazard waste.
A biohazard is defined as any biological substances that pose a threat to the health of living organisms. By now you know that biohazards can include certain bacteria, viruses and medical waste.
Microorganisms Safety Guide
- Treat all microorganisms as potential pathogens.
- Sterilize equipment and materials.
- Disinfect work areas before and after use.
- Wash your hands.
- Never pipette by mouth.
- Do not eat or drink in the lab, nor store food in areas where microorganisms are stored.
- Label everything clearly.
Masks andprotective eye wear, such as goggles or a face shield, help protect your eyes, mouth, and nose from droplets of blood and other body fluids. Always wear a mask and protective eye wear if you are doing a procedure that may expose you to splashes or sprays of blood or body fluids.
Follow these safety precautions:
- Carefully read the ingredient list of any product or chemical you use.
- Purchase the proper personal protective equipment like gloves or goggles.
- Be aware of the hazardous materials you come in contact with.
- Follow safe procedures when you handle hazardous material.
Use the largest vein and needle appropriate for blood collection. Never use any needle smaller than a 23 gauge size. Use minimal alcohol on fur/skin. Remove the needle from the syringe before dispensing into the blood tube, unless using a closed vacuum blood collection system.
Follow these safety precautions:
- Carefully read the ingredient list of any product or chemical you use.
- Purchase the proper personal protective equipment like gloves or goggles.
- Be aware of the hazardous materials you come in contact with.
- Follow safe procedures when you handle hazardous material.
Medical Definition of Biosafety
Biosafety: The application of knowledge, techniques and equipment to prevent personal, laboratory and environmental exposure to potentially infectious agents or biohazards. Biosafety defines the containment conditions under which infectious agents can be safely manipulated.Using work practices that block routes of exposure can prevent workplace infection. Good microbiological techniques must always be used in the laboratory: Eating, drinking, smoking, applying cosmetics or storing food for human consumption in laboratories is strictly prohibited.
These sterilization precautions ensure the safety of your patients and yourself. Mistakes can harm your, your patient, and even patients following them. You could also compromise the specimen that you collect and make it worthless to the doctor.
While risks associated with exposure to blood and tissues infected with Hepatitis B can be mitigated by vaccination of laboratory workers, there is always the potential for infection from the risk of other infectious agents such as Hepatitis C, HIV and CJD when handling human specimens.
Biohazardous waste, also called infectious waste or biomedical waste, is any waste containing infectious materials or potentially infectious substances such as blood. Of special concern are sharp wastes such as needles, blades, glass pipettes, and other wastes that can cause injury during handling.
A biohazard is defined as any biological substances that pose a threat to the health of living organisms. By now you know that biohazards can include certain bacteria, viruses and medical waste.
Human Body Fluids.
Items that have been contaminated with blood, saliva, secretions, cerebral spinal fluid, amniotic fluid, peritoneal fluid, pericardial fluid, pleural fluid, and/or synovial fluid in any way, shape, or form, are biohazardous. These wastes represent the majority of hazardous waste.Only biohazardous waste should be placed inside red bags for disposal. Dispose of items such as plastic vaginal speculums, used specimen swabs, used glucose test strips, urine dipsticks, blood-soaked drapes and gloves, and anything contaminated with OPIM in a red bag.
Animal Pathogens: Pathogenic microorganisms that can cause disease in animals; Biohazardous Waste: Includes bloodborne pathogens, infectious wastes, animal pathogens and plant pathogens; Infectious Waste: Human or animal pathogenic cultures and tissue body fluids.
Body fluids which constitute a higher risk of containing potential biohazards include:
- Human blood and blood products, including plasma, serum, and blood components.
- Semen and vaginal secretions.
- Vomit or feces.
Medical waste is disposed of by first making it safe through a sterilization process. Waste that cannot be recycled, like gauze or needles, still needs to be made sanitary and non-hazardous before it can be disposed of. This process is usually done by using an autoclave.
Containers with a capacity of 100 ml or less are not required to have hazard statements or precautionary statements on the label. Labels on containers with a capacity of 3 ml or less can be designed to be removed at the work place if the label interferes with the normal use of the product.
WHMIS , now known as WHMIS 2015, has changed to: adopt new international standards for classifying hazardous workplace chemicals and giving information and safety data sheets. classify hazardous products into two broad hazard groups, physical hazards and health hazards.
How Can I Protect Myself from Biohazards in the Workplace?
- Treating each situation as potentially dangerous.
- Washing your hands frequently with warm water and soap.
- Wearing personal protective equipment (PPE) when responding to situations involving biohazards.
WHMIS will now be referred to as WHIMIS
1988 and the newly updated GHS and
WHMIS will be referred to as
WHMIS 2015.

If the hazardous product is always used in the container with the supplier label, no other label is required. A workplace label is required when: a hazardous product is decanted (e.g., transferred or poured) into another container, or. a supplier label becomes lost or illegible (unreadable).
WHMIS 2015 Workplace Hazardous Materials Information System (WHMIS) is new. Since 1988, WHMIS has been Canada's hazard communication system for workplace chemicals. For clarity, the old requirements are referred to as “WHMIS 1988” and the new requirements are referred to as “WHMIS 2015”.
