It does not differentiate between business or residential. They are State & Federal Regs.
Here's more...
Can I have an employee, family member, or colleague clean the crime scene?
Federal Regulation 29CFR1910.1030 states that
no employee can be placed in a position to be exposed to blood spills without first:
1.Receiving blood-borne pathogen (BBP) training.
2.Having a written BBP exposure control plan.
3.Having been provided personal protective equipment.
4.Having been offered Hepatitis B vaccine and exposure evaluation and follow-up.
5.Being provided with a method to remove and properly store the bio-hazardous waste in properly marked containers for disposal at an approved site.
All employee regulations. Family members are not employees.
Agree to disagree? or find me a regulation that states private residence.
