Legal requirements for crime scene cleanup businesses are set by individual states or municipalities. At a minimum, crime scene cleaners must follow laws regarding the handling and disposal of biohazardous waste.
All crime scene cleaners should be trained to safely handle biohazard materials, such as blood and human remains, according to OSHA (Occupational Health and Safety Administration) guidelines.
The ABRA (American Bio-Recovery Association) offers certification as a Bio Recovery Technician via accredited classes from private agencies.
The Restoration Industry Association (RIA) offers courses leading to certification in a variety of specialties related to restoring property after a damaging incident.
Because crime scene cleaners deal with both hazardous waste and toxic cleaning chemicals, a class in the proper use of respiratory training is highly recommended for crime scene cleaners, where not required by law.
