biohazard remediationBiohazard Remediation: A Field Guide, Case 10

An occupant attempted suicide with a knife beginning in the bedroom on the mattress continuing into the den and kitchen area and eventually collapsing in the bathroom. The contamination (blood and body fluids) in the hotel suite was dispersed throughout the entire unit. Two technicians performed decontamination work for a total of 4 work hours to remove the contamination. During this process, 2 individual sets of personal protective equipment, 5 quarts of disinfectants, and 6 quarts of biological indicator (H2O2) were consumed.

The blood affected material extends to portions of the room near the bed from the removal of bedding material and movement of the injured. Contamination continues to the bathroom and kitchen accumulating in the bathtub and across various surfaces (marble, carpet, cabinets, furniture). Gloves and all applicable personal protective equipment (PPE) has been provided to create a protective barrier in between the technician and the site environmental hazards, such as biological residue, in accordance with OSHA Standard Personal Protective Equipment 1910.132.

Mobilization of resources required for this type of project would take approximately 45-90 minutes based on familiarity with the process, easy access to required chemicals and equipment, in addition to, transporting these items to the scene. This time includes the removal of the personal protective equipment, the required tools, portable container with disinfectant solution, and corrugated regulated medical waste containers from the responding vehicle after arriving on scene.

It was of the utmost importance to be discreet in route to the room and cover the outside of the medical waste boxes with contractor bags. The personal protective equipment used on this biohazard remediation project was PureShield high risk gloves, plastic face shields, various respirators, and KleenGuard Ultra Bloodborne pathogen rated suits.

All of the towels in the bathroom and bedroom floor were affected by blood due to splatter or used as a temporary bandage. These towels and the bedding were the major contributors to Regulated Medical Waste volume. Plastic-bristle scrub brushes were used to clean grout and uneven surfaces with disinfectant. A face shield is required due to the risk of blood and solution splashing from the scrubbing bristles of the scrub brush.

Plastic water bottles were used as a sharps container for the knife used. All attempts were made to include all the supplies from the response vehicle in order to keep from leaving the room until the work was complete. Security from the hotel had to escort the technicians from the response vehicle and back. Review surfaces that are uneven in color very carefully. Blood droplets can blend in with dark surfaces and multi-colored surfaces such as marble counter tops. Use hydrogen peroxide (H2O2, 3%) as quality control by misting areas and looking for any area that reacts by foaming up. The comforter, blankets, bed cover, and pillows were affected by blood and treated as regulated biological waste and housed in biohazard labeled red bags.

These biohazard bags were placed in large black trash bags (see right) in order to carry the biohazard waste down the luxury hotel hallway without causing alarm. An enzyme (Neutron D-Molish) was use to break down the small-droplet blood stains on the carpet.

Case Studies (Biohazard Remediation)

The majority of the lost blood volume was absorbed by the bedding and towels and there wasn’t any blood pooling from the incident in the carpeted area. Conventional cleaning products and disinfectant were used on the residual stains once the blood had been dissolved by the enzyme treatments. This enzyme is sprayed as a mist over the blood (soaking it but not creating a pool of fluid) on the carpet. Paper towels (dry) are then laid over the enzyme soaked stains.

These paper towels absorb the diluted blood in order to recover it from the surface of the carpet. Once this cycle is repeated with additional enzymes and layers of dry towels, use conventional cleaners to treat any residual stains and spray a layer of disinfectant on the area. To neutralize any residual odor, the entire unit was treated with an atomizing fog of Get The Odor Out. This solution does not leave stains on what is treated and is useful as a secondary disinfectant. The carpet was salvaged due to the small droplets opposed to pooling in addition to the mattress.

The carpet, couch and mattress were all sprayed directly with the atomized fog. A hospital grade disinfectant (Shockwave) was used throughout the unit and to kill the enzymes used once the treatments were finished.

Crime Statistics: Detroit

Detroit with a 2010 population of 899,447 saw their property crime incidents fall from 50,929 in 2009 to 47,787 in 2010. This 6.7% decrease was alongside Detroit’s decline in violent crime rates too. Robberies had a 7.8% decrease and as for burglary the decrease was slightly higher reaching 11%. The Detroit Police Department is utilizing online tools such as Crime Mapping because they realize awareness is prevention and by taking the right steps this is bring community involvement and building a safer environment.

Case 1: Attempted Suicide in a Hotel Room

biohazard remediation hoarding and OSHA compliant crime scene clean upThe metal scrapers (paint scrapers) are very useful across the concrete sub floor and put distance in between the gloved-hand and bloody concrete. When biological waste has been contained in the medical waste boxes, as well as, the conventional waste prepared for transport, the technicians remove their personal protective equipment and place it in a medical waste box. All the PPE is disposed of as medical waste.  The room then has a comprehensive fog applied with Get The Odor Out to restore hygiene and improve comfort.  The technicians have easy access to a container clearly labeled "Biohazard" with the biohazard symbol clearly displayed and a red bag insert for biomedical waste to be placed inside.

 

Case 2: Hoarding and Gross Filth in a Home

biohazard remediation hoarding and OSHA compliant crime scene clean upThe deceased rested in the bedroom of a home affected by heavy hoarding and filth. The project began with the initial assessment of the contaminated environment. The primary biological contaminated area consisted of a significant amount of blood and body fluid in the middle of the front bedroom where the 1st responders knocked down a brick wall to recover the body. After the initial assessment and development of the waste removal plan, all applicable PPE was applied and then the entire area was treated with the primary disinfectant Shockwave.  The disinfectant was applied countless times during this remediation process. During the dwell time needed for the disinfectant application, a review was performed in the collateral area to better define the biological contamination plume and for quality control. The decomposition area on this project was in a front room.

Case 3: Tear Gas Residue in a Home

biohazard remediation hoarding and OSHA compliant crime scene clean upSeveral teargas canisters were shot into a home (”I’m not coming out!”; drug-related activity brought police action). Multiple canisters not only made it into the home but also penetrated the wall cavities and leaving a high concentration of reacted dust in the recess. Once the entire structure was treated with the teargas neutralizing solution, technicians then began to recover the dust left by the teargas projectiles. While the technicians were collecting reactive dust, a HEPA filtered Air scrubber was run in other portions of the house to gather dust that was disturbed during cleaning and to restore air-quality.  The MSDS for the tear gas neutralizing chemical is on hand in accordance with OSHA Standard Hazard Communication 1910.1200. The Get The Odor Out formula used is specifically formulated to neutralize CS and CN teargas particulate.

Case 4: Hoarding and High-volume filth Cleaning

biohazard remediation hoarding and OSHA compliant crime scene clean upThe project begins with the initial assessment of the contaminated environment. The 2-story home was condemned by the local health department. There were dozens of cats living inside and outside the home, saturating everything in urine and feces. After the initial assessment and development of the waste removal plan, application of all applicable PPE and then spray the entire area with the primary disinfectant, Shockwave. During the dwell time needed for the disinfectant application, review the collateral area to better define the biological contamination plume and for quality control.  The scope included placing the personal salvageable items in a segregated, concentrated area in the garage and portions of the home in order to remove contents/trash and manipulate contents in preparation for disposal. These actions were to relieve the home from condemnation from the local health department.

Case 5: Human decomposition in an apartment

biohazard remediation hoarding and OSHA compliant crime scene clean upThe bedding, mattress, and portions of carpet and pad were affected by biological fluids. A person in their 40s died and was left unattended for over 2 weeks. This decomposition produced fluids that penetrated the mattress, box springs, carpet, and pad. The decomposition odor present was very challenging. This affected material was segregated as medical waste and contained and the entire area was disinfected multiple times. Once the top layer of bedding and the pillow top of the mattress were removed, the fluids that settled on the bottom-side of the mattress were exposed.  The clear labeling on the biologically contaminated material is shown. This material was sealed in 4 mil plastic for safe transport and labeled in accordance with OSHA Standard 1910.1030 Bloodborne Pathogens.

Case 6: Corner Store Stabbing

biohazard remediation hoarding and OSHA compliant crime scene clean upThe contamination (blood) on the property was dispersed throughout the store front to the photo counter and out into the parking lot. This blood spill was in relation to a stabbing that took place in the parking lot and the victim ran into the store for help before the police and EMS 1st responders arrived. The blood on the scene was splatter across a large area opposed to pooling and a concentration in a small area. The actual inputs on the project were 8 hours of technician labor, 3 gallons of disinfectant, and 2 sets of personal protective equipment (PPE).  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.

Case 7: Airbag deployment blood spill

biohazard remediation hoarding and OSHA compliant crime scene clean upTo begin the project, the outside of the car must be disinfected after the application of personal protective equipment. Once the outside of the car has been treated with the primary disinfectant (Shockwave), the technician then opened the door and begin applying disinfectant throughout the interior. The cause of the blood spill was an airbag deployment. The airbag injured the driver significantly and once the driver was removed from the car the blood spread from the interior down the exterior of the car on the driver side doors. Carpet found in a home is best cut from the underside with a razor. Pushing a razor blade through the woven fabric underneath provides a more consistent surface for the blade opposed to the long carpet fiber on the top side.  The blood was recovered from the non-porous surfaces with disinfectant solution and cloth rags and discarded as medical waste. Cotton swabs were used to recover blood and disinfect sensitive areas such as electronics controls.

Case 8: Tear gas residue carpet salvage in a home

biohazard remediation hoarding and OSHA compliant crime scene clean upA gentleman stood in the doorway of his wife’s home and screamed at the police outside, “I have a gun and I’m not afraid to use it!” or something close to that according to his wife. The husband lived during the police action that followed his comments but the home was damaged from the tear gas projectiles fired into it. The contamination (tear gas) on the property was dispersed throughout the entire home. A chemical fogger and manual hand sprayer were used to distribute the tear gas neutralizing solution. The MSDS for the tear gas neutralizing chemical is on hand in accordance with OSHA Standard Hazard Communication 1910.1200.  This extractor was able to recover the teargas powder that was neutralized but still rested down in the carpet and surfaces. The neutralizing solution is sprayed out of nozzles on the end of the wand and recovered through the larger vacuum hose which then settles in the recovery tank.

Case 9: Methamphetamine Lab in an apartment

biohazard remediation hoarding and OSHA compliant crime scene clean upThe decontamination work consisted of recovering the residual residue produced during the operation of a clandestine methamphetamine lab (user level) in a one bedroom apartment. This user level lab was established in the utility room for segregation. The police were aware of the occupant’s clandestine manufacturing of methamphetamine and they were waiting for him to cook before raiding the apartment. The police succeeded in their plan and the occupant was cooking methamphetamine when they arrived to shut it all down.  The base ingredient of this product is Stabilized Chlorine Dioxide (2000 PPM), an EPA listed light-duty bactericide used to restore biological hygiene. This solution also contributes to oxidizing the compounds found in any trace residue from the meth lab on hard-to-reach surfaces in recess areas. In summary, by removing belongings, carpet, and pad all surfaces were exposed to treat with neutralizer and the contents were disposed of.
