Biomedical Waste Recovery and Disposal



Case 6 Photos

The tile floor was cleaned and disinfected.  The uneven surfaces affected by blood were disinfected and cleaned with 20% peroxide solution and scrub pads.  Beware of scrub brushes on surfaces such as the cart above because the bristles can spring when scrubbing and spread blood by droplets thrown from the bristles.  The technicians have been instructed of the hazards associated with the chemicals used, Shockwave MSDS, to comply with OSHA Standard 1910.1200 Hazard Communication.  


This transmittal of information is to be accomplished by means of comprehensive hazard communication programs, which are to include container labeling and other forms of warning, material safety data sheets (MSDS), and employee training.  The 24-hour store was  open for business upon completion of the biohazard remediation.  


To restore biological hygiene outside the store, the primary disinfectant was sprayed evenly on the pavement and the doorway’s adjoining surfaces.  In addition to this application of the primary disinfectant, residual blood stains on the concrete were lifted with 20% peroxide solution.


In summary, the blood affected area stretched across multiple surfaces such as non-porous tile and porous concrete.  This area was disinfected multiple times, including doors, hand rails, and counter tops.  All the food merchandise in the affected area was disposed of as medical waste.  


Once all the blood was recovered from surfaces and the bottom portion of shopping carts, the residual stains on the concrete were treated.  Residual stains on concrete were sprayed with a final application (mist not a pool) of peroxide solution (3%) which was left to evaporate.
