BiohazardsFor our purposes, biohazards may be infected blood or tissue from crime scenes, suicides, and unattended deaths. Such infectious environments must be isolated until all cleaning, disinfecting, and removal is carried out. Extreme hygienic exaggeration should be used by the novice as well as the professional. Always clean biohazardous environments as if cleaning for a toddler's use. Never remove biohazardous material without wearing gloves. "For cleaning blood or bloody fluids from floorsbedetc.you can use household rubber gloves." Wear protection over eyes-nose-and-mouth. Have a safe means of exit and a place to decontaminate yourself and clothing. Blood as a biohazard will consist of wet or moist blood or dried flaky (scabbing) blood. Adding chemicals to blood something like bleach will either destroy the blood or destroy its source of food or both. Bleach will begin to break down once in contact with blood or any other organic matter. Dried blood that flakes may easily become aerosolized if mishandled. Contact with airborne blood places the cleaner at risk of infectious disease. Before removing moisten flaking (scabbing) blood. Cause it not to become airborne. Cover flaked blood with paper towels and lightly moisten with a disinfectant (bleach) from afar. Use a spray bottle while making wide misting applications to the paper towels' surface. Before removing blood ensure that it is moist enough not to flake but not dripping. Dry paper towels may be used to contain wet blood. Allow towels to dwell until dry. Flush in small quantities or gently place inside two thick plastic bags. Seal tightly with duct tape. Directly dispose of in a landfill.TOP Dripping wet blood is considered biohazardous and universally considered infectious until proven otherwise. Contain blood from afar; disinfect it. Pour blood down the sanitary sewer if you are not going to seal it for transfer. Thoroughly wash hands. See Blood Cleanup 1blood cleanup 2and blood cleanup 3. General. Universal precautions shall be observed to prevent contact with blood or other potentially infectious materials. Under circumstances in which differentiation between body fluid types is difficult or impossible all body fluids shall be considered potentially infectious materials. (return) Useful disinfectants may be found here: Blood Spills: see index at http://www.bccdc.org/downloads/pdf/epid/reports/CDManual_ Vinegar: http://www.apple-cider-vinegar-benefits.com/vinegar-as-a-disinfectant.html The Center for Disease Control recommends using chemicals or autoclave to decontaminate. This recommendation is made in the context of laboratory work. In the home on the crime scene my philosophy is not to tolerate biowaste that may be biohazardous. I destroy and/or encapsulate any offending materials. I see no point in exposing anyone to pathogens needlessly. Household bleach is a
wonderful but very corrosive disinfectant. It is a "midrange
disinfectant." Bleach has a wide bacterial killing spectrum. It is
inexpensive and found on most market shelves. However, bleach is
extremely dangerous in the presence of acids, including urine. Open
bleach bottles lose their strength; it loses strength when applied to
organic material like blood and decomposing matter. Bleach must be used
cautiously, wisely.TOP
Death Odors - MiasmaViolent
deaths usually involve a great loss of blood and tissue, OPIM (Other
Potentially Infectious Materials). The loss of blood and tissue, the
environmental conditions, and other circumstances will aid in the
production of offensive death scene odors, miasma.
Sometimes
miasma lingers because of poor ventilation. Sometimes miasma will
linger because it has permeated porous materials: fabrics, paper, wood, and more.
We do our best to remove the odors associated with crime scenes and other death scenes. However,
removing the source material will not always return the scene to its
pre-incident condition for some time. Time and heavy ventilation and
removal of miasma permeated materials will help return the scene to a
more "normal" condition.
We can apply chemicals to help increase miasma's departure from the scene, but even chemicals have their limits. Ask about our odor control policies and methods if this is a concern. My training and education includes the following:
How long does it take to clean a crime scene? Usually one to two days will be enough depending upon unforeseen's, fogging and ozone gas application.
This is what I know:
(Clutter adds work to the above.) Number 1 above will take two long days. Number 2 will create the least biowaste unless there is poor grouting. Number 3 will create the most biowaste. Number 4 creates the greatest hazard and may take one long day. Number 2 and 4 may require chasing fluids below the toilet. Number 5 is a horrific wild card. Call for a quote. There may be unforeseen issues possible for the above examples, like migrating fluids and floors and walls to remove. (see migration). Unforeseens become apparent only when the scene is taken apart. My prices anticipate unforeseens. Email me with the offered quote and I will email my acceptance. This is a contract for legal purposes in any civil court. |
