For
our purposes, biohazards may be infected blood or tissue from crime
scenes, suicides, and unattended deaths. Such infectious envirments
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 floors, bed, etc., 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 flakey
(sabbing) 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 mosten 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.
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.

OSHA 1910.1030(d)(1)
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)

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 needlessly exposing anyone to pathogens.
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.
