Types of Biohazard Spills and their Cleaning solutions

Biohazard spills are of different types, and they require different cleaning solutions.

Blood Biohazard Spill

Blood spills can happen any time when we least expect. They may happen from a car accident, a drug overdose incident, to someone who has been killed via a gunshot or has been stabbed using a sharp object. Whichever the reason, the blood spillage has to be cleaned up, and the right equipment and cleaning agents have to be applied to ensure no infection occurs.

Cleaning Solution for Blood Clean Up?

For cleaning up hazardous blood spillages, most companies use a solution of one part of 0.5% chlorine diluted in nine parts of water. This solution for disinfecting and cleaning blood hazardous spillage from surfaces should include 0.5% of chlorine concentration. Due to the way chlorine solution gradually loses strength within 24 hours after being freshly prepared, it is crucial to apply it shortly after preparation on the blood hazardous spillage. This is to ensure adequate disinfection takes place.

The procedure for preparing a 1:10 solution freshly for disinfecting a hazardous blood spillage can be done by adding one volume of household bleach to nine volumes of clean water as unclean water may contain organic matter, which destroys chlorine.

Standard cleaning solutions which have been successfully used for cleaning blood hazardous other than household bleach are Calcium hypochlorite powder or granules (70%) such as Sochlor NADDC granules.

Mold Biohazard Spill

Mold may grow around your home, and you may not realize it early enough. This is because mold loves warm, humid places, which most of the time are out of sight. Once mold spreads, it may be highly challenging to get rid of it. The mold that has spread out can become very problematic as it can cause respiratory diseases such as asthma and allergies. To counteract the spread of the mold biohazard spill, mold remediation is applied to prevent further spread of the mold. Remediation is the process that is done to amend the outbreak of mold spread by reverting it back to natural levels and stopping the abnormal spread from happening again.

Mold is best cleaned using white distilled vinegar with 5% acidity or cleaning vinegar with 6% acidity. Bleach can also be used, but vinegar has been proven to be a better cleaning agent for mold than bleach. Brands such as Allens cleaning vinegar have been used for mold remediation and achieved excellent results.

Reasons for using Vinegar over Bleach for mold remediation
• Vinegar kills the mold from the surface to the membrane level, while bleach only kills the mold from the surface and does not penetrate the membrane.
• The use of bleach can multiply mold growth since when applying bleach to a mold surface, mold colonies detect bleach as a threat and make the mold grow more vigorously. This is because mold may feed on the bleach hence using it to multiply itself.

Bleach is also discouraged for use by EPA, and thus use of 5% vinegar or 6% vinegar is highly recommended as a cleaning solution for mold remediation.

Animal Waste Biohazard

Animal waste biohazards such as animal waste may contain various bacteria and viruses that can be harmful to you and the surrounding people.  Animal waste and droppings from bats, rodents, birds, and even the pets we own can be potentially dangerous.
