How can providing first aid care be hazardous for the person providing the assistance?

Providing first aid can be hazardous to the provider if the accident victim is infected with a communicable disease. Many body fluids, such as blood and lymph, can serve as vectors for disease transmission. If first aid responders come into direct contact with body fluids while providing aid, they may be at risk. In addition, if the environmental conditions that led to the accident in the first place still exist, then the responders may be in the same danger for injury as the person being assisted.
