Yes, you need to be trained to clean up blood and other biohazards. Bloodborne pathogens, such as HIV and Hepatitis B, are highly contagious and can be transmitted through contact with infected blood. Cleaning up blood and other biohazards requires specialized training and equipment to ensure it is done safely and effectively. Professional biohazard cleanup companies employ trained technicians who are equipped with the necessary skills and tools to properly handle and dispose of biohazardous materials. Attempting to clean up blood or other biohazards without proper training and equipment can put you and others at risk of infection and disease.
