Bloodborne Pathogens for Canada

**Bloodborne Pathogens (BBPs) in Canada** are infectious microorganisms present in human blood that can cause serious health conditions such as HIV, Hepatitis B, and Hepatitis C. Workers who may be exposed to BBPs in the course of their work, especially in healthcare settings or emergency response situations, must understand the risks and follow proper procedures to prevent exposure.

### Key Points about Bloodborne Pathogens in Canada:

#### **1. Legislation and Regulations:**
In Canada, the **Occupational Health and Safety (OHS) regulations** govern the protection of workers from exposure to bloodborne pathogens. These regulations are primarily enforced by:
- **Workplace Health and Safety (WHS)** regulations set by provincial or territorial authorities.
- The **Canada Labour Code (CLC)** and its **Regulations** for federally regulated workplaces.
- The **Occupational Health and Safety Act (OHSA)** at the provincial level.

For instance, in Ontario, the **Regulation for Health Care and Residential Facilities (O. Reg. 67/93)** provides specific requirements related to BBP exposure in health settings. Similar regulations exist in other provinces, with each adapting to its local context.

#### **2. Common Bloodborne Pathogens:**
The primary BBPs that workers may encounter include:
- **Hepatitis B (HBV)**: A viral infection that can lead to chronic liver disease or liver cancer.
- **Hepatitis C (HCV)**: A viral infection that can cause chronic liver disease and is a leading cause of liver transplants.
- **Human Immunodeficiency Virus (HIV)**: The virus that causes AIDS, a condition that weakens the immune system.

### **3. Risk of Exposure:**
Workers may be at risk of BBP exposure in a variety of settings, including:
- **Healthcare**: Nurses, doctors, laboratory technicians, and other healthcare workers who may handle blood or other potentially infectious materials.
- **Emergency Services**: Paramedics, firefighters, and first responders who might come in contact with blood or body fluids during accidents or medical emergencies.
- **Social Services**: Workers in community or home care services, including those providing healthcare in patients' homes or working with individuals who have communicable diseases.
- **Cleaning and Maintenance**: Custodians, janitors, or laundry workers who handle soiled materials that might contain blood or bodily fluids.

#### **4. Universal Precautions (UP) and Infection Control:**
In Canada, **universal precautions** are a key measure to prevent BBP exposure. This means treating all blood and bodily fluids as potentially infectious, regardless of the patient’s diagnosis. To minimize the risk, workers should follow the following practices:
- **Personal Protective Equipment (PPE)**: Use gloves, gowns, masks, face shields, and goggles to prevent direct contact with blood or bodily fluids.
- **Needle Safety**: Use safety-engineered needles or syringes to avoid needlestick injuries.
- **Proper Waste Disposal**: Dispose of contaminated needles and other sharp objects in puncture-resistant containers and follow proper disposal protocols for contaminated materials.
- **Hand Hygiene**: Wash hands frequently with soap and water, or use alcohol-based hand sanitizers, after handling blood or potentially infectious materials.

#### **5. Bloodborne Pathogen Exposure Control Plan:**
Canadian workplaces that are at risk of BBP exposure are required to develop an **Exposure Control Plan (ECP)**. This plan outlines procedures for:
- Identifying and assessing potential BBP exposure risks.
- Implementing control measures to eliminate or minimize exposure.
- Training workers on safety practices, including the use of PPE and the proper disposal of contaminated materials.
- Monitoring the effectiveness of the control measures.
- Providing post-exposure follow-up procedures for workers exposed to bloodborne pathogens.

#### **6. Training and Education:**
Employers must provide training to workers about bloodborne pathogens and infection control practices. The training should include:
- How BBPs are transmitted.
- Methods of preventing exposure.
- Proper use of PPE and safety equipment.
- Steps to take in case of a bloodborne pathogen exposure, including first aid, reporting, and seeking medical treatment.
- Regular updates to training, especially if new information or procedures arise.

#### **7. Post-Exposure Protocol:**
If a worker is exposed to blood or bodily fluids that may contain a bloodborne pathogen, the following post-exposure steps are critical:
- **Immediate Cleaning**: Wash the exposed area with soap and water as soon as possible. In case of a mucous membrane exposure (e.g., eyes or mouth), flush the area with water or saline.
- **Reporting the Exposure**: Notify a supervisor and report the incident immediately to ensure prompt medical evaluation and follow-up.
- **Medical Evaluation**: Seek immediate medical advice, including testing for BBPs and discussing the need for post-exposure prophylaxis (PEP) treatment, which may help reduce the risk of infection (for HIV, for example).
- **Follow-Up Testing**: Regular testing for BBPs (e.g., Hepatitis B, C, and HIV) may be required after exposure to ensure the worker has not contracted an infection.

#### **8. Vaccination and Preventive Measures:**
- **Hepatitis B Vaccination**: Vaccination for Hepatitis B is recommended for workers who are at risk of exposure. Employers should provide this vaccination as part of their health and safety program.
- **Post-Exposure Prophylaxis (PEP)**: PEP treatment is available for workers exposed to HIV and must be started within 72 hours of exposure for effectiveness.

### **9. Employer Responsibilities:**
Employers in Canada are responsible for:
- Ensuring that workers are trained in bloodborne pathogen prevention.
- Providing appropriate PPE, vaccination, and medical follow-up services.
- Ensuring that all protocols, including emergency procedures and the Exposure Control Plan, are followed.
- Maintaining records of training, incidents, and medical evaluations related to bloodborne pathogen exposure.

### **Conclusion:**
Bloodborne pathogens present a significant risk in many workplaces in Canada, particularly in healthcare and emergency response. However, by adhering to regulations, following universal precautions, and providing proper training, employers can significantly reduce the risk of exposure and protect the health and safety of workers. Regular assessment and updates to safety protocols are essential to maintaining a safe work environment.
