Dealing With Black Mold

The dreaded black mold, otherwise known as Stachybotrys Chartarum or Stachybotrys Atra, is widely reviled and feared when it contaminates a building.  This is because this particular species of mold is infamous for its release of mycotoxins through its airborne spores.  These toxic particles are harmful to humans even in low concentrations, and can poison a person’s respiratory system, before spreading its affliction to the rest of the body.  Black mold poisoning causes a wide variety of ill effects, from relatively mild symptoms such as headaches, coughing and the development of rashes and hives, to much more serious signs, such as bleeding in the lungs, liver and other internal organ damage, and urinary tract infections.  When encountering black mold, one has to be very careful not to avoid exposure, or risk getting very sick.

   

 

  

Black mold in smaller quantities can probably be dealt with without having to go to the experts, but this is not your conventional household mold, so you had better make adequate preparations.  Purchase disposable cleaning supplies for the task, as you will most certainly be getting rid of them afterwards, due to the contamination.  Pick up some rubber gloves, dollar sponges and handheld scrubbers, as well.  It is also recommended that you wear an N-95 respirator to avoid accidentally inhaling black mold particles.  The clothes on your back should probably be things that you intend to burn when you are done.  Lastly, arm yourself with a solution mix of bleach and water, or pick up some extra strength bleach-based mold remover, and have it ready in a spray bottle. 

When you are ready, start spraying the affected areas, wait for a few minutes, and then scrub the mold away until the surface is clean.  Leave the solution on a little longer for areas that are harder to scrub, so that they get loosened up quickly.  A bleach-water solution should be safe on most surfaces, but if you want to be sure, you may want to lay down some plastic sheets so that the solution does not ruin them. 

If you discover furniture, carpeting or upholstery that has been thoroughly contaminated, you should consider discarding it entirely, as the mold spores will be almost impossible to remove entirely.  Once every area with black mold has been cleaned out, use a dryer to remove moisture, to minimize the chances of the mold returning. 

If the black mold infestation is pretty severe, like it was in the areas flooded by Hurricane Katrina some years back, you should leave the cleaning work to the professionals.  A qualified mold remediator will be able to accomplish the task without exposing himself or you to unnecessary risk.  He will be able to check for the primary sources of the infestation, and deal with moisture concerns that may be aggravating the situation.  More importantly, he will be able to spot the black mold growths that may be concealed behind walls or tiles, which will continue to release harmful spores into the air even if you don’t see them.  Admittedly, there may be a high price to pay for a remediator’s services, but it should be weighed against the cost of having to write your home off as another black mold casualty.
