It is my understanding that blood can be dangerous in the sense that it carries pathogens that can make anyone sick. It carry particularly scary pathogens like HIV, Hepatitis C etc. These pathogens can be contracted by anyone.

The importance of good cleaning and disinfecting practice by employees are important to prevent spreading any harmful diseases. those that deal with syringe's are at a risk of being poked and need to take precaution and follow OSHA guides on how to properly dispose needles.

It is important that all employees are trained on bloodborne pathogens to keep themselves and others safe. OSHA  Guidelines should be followed. good house cleaning will make for a safer work environment also reducing the the risk of injury.
