Mold contamination to this extent is a bit serious matter. However, some precautionary measures are to be taken that are required for level one and level two mold attack. Apart from those, you must pay attention to the following:

Symptoms of mold exposure may include nasal and sinus congestion; runny nose, eye irritation; itchy, red, watery eyes, respiratory problems, such as wheezing and difficulty breathing, chest tightness, cough, throat irritation, skin irritation (such as a rash), headache, and persistent sneezing.[4] Immune-compromised people and people with chronic lung illnesses, such as obstructive lung disease, may get serious infections in their lungs when they are exposed to mold. These people should stay away from areas that are likely to have molds, such as compost piles, cut grass, and wooded areas.
How do you keep mold out of buildings and homes?
If there is a small area of mold growing underneath air conditioning systems, it would be safe to apply precautions from levels 1-2 and remediate the mold contamination. But, all remediation procedures for air conditioning units and HVAC systems should be left to the professionals. The following precautions should be taken:

During mold remediation in the U.S., the level of contamination dictates the protection level for remediation workers.[24] Contamination levels have been enumerated as I, II, III, and IV:[25]
After correcting water or moisture infiltration, the prompt removal of contaminated material and structural repair is the primary response to mold contamination in buildings. In all situations, the underlying cause of water accumulation must be rectified or the mold growth will reoccur. Emphasis should be placed on preventing contamination through proper building and HVAC system maintenance and prompt repair of water damaged areas.

Are there any circumstances where people should vacate a home or other building because of mold?
We usually find only trace levels of Penicillium/Aspergillus indoors in residential buildings and offices, so counts even close to the “clean” level may make further investigation a reasonable course of
Molds are usually not a problem unless mold spores land on a damp spot and begin growing. They digest whatever they land on in order to survive. There are molds that grow on wood, paper, carpet, foods, and insulation, while other molds feast on the everyday dust and dirt that gather in the moist regions of a building.
3. Vacate from your work area any infants less than 12 months old, individuals recovering from recent surgery, anyone with a suppressed immune system, or people with chronic lung diseases such as asthma, severe allergies, emphysema, etc.
Mold Exposure Levels – Sources of Variation in Mold Toxicity – a warning about single numbers
Please note: Dead mold may still cause allergic reactions in some people, so it is not enough to simply kill the mold, it must also be removed.
It is interesting how mold can grow very fast and spread in a home. Definitely not good for your health! So to just leave it and do nothing is a ticking time bomb. Mold remediation is costly but well worth it if you have an infestation of mold that needs to be taken care of. A mold specialist can get to the source of the problem and get rid of the mold so it won’t come back.
HEPA (High-Efficiency Particulate Air) vacuums are recommended for the final cleanup of remediation areas after materials have been thoroughly dried and contaminated materials removed. HEPA vacuums also are recommended for cleanup of dust that may have settled on surfaces outside the remediation area. Care must be taken to assure that the filter is properly seated in the vacuum so that all the air passes through the filter. When changing the vacuum filter, remediators should wear respirators, appropriate personal protective clothing, gloves, and eye protection to prevent exposure to any captured mold and other contaminants. The filter and contents of the HEPA vacuum must be disposed of in impermeable bags or containers in such a way as to prevent the release of the debris.
what do mold remediation companies do Some mold produce mycotoxins, chemical components of their cells walls, that can pose serious health risks to humans and animals. “Toxic mold” refers to mold which produces mycotoxins, such as Stachybotrys chartarum. Exposure to high levels of mycotoxins can lead to neurological problems and death. Prolonged exposure (for example, daily exposure) can be particularly harmful. Mycotoxins can persist in the indoor environment even after the death of the fungi. They can adhere to dust particles and can spread through the air attached to these dust particles or spores.[3] There must be very specific temperature and humidity conditions in order for fungi to produce mycotoxins.[3]
How Do I Find A Reputable Mold Remediation Company?
Because common building materials are capable of sustaining mold growth and mold spores are ubiquitous, mold growth in an indoor environment is typically related to water or moisture exposure and may be caused by incomplete drying of flooring materials (such as concrete). Flooding, leaky roofs, building-maintenance, or indoor-plumbing problems can lead to interior mold growth. Water vapor commonly condenses on surfaces cooler than the moisture-laden air, enabling mold to flourish.[8] This moisture vapor passes through walls and ceilings, typically condensing during the winter in climates with a long heating season. Floors over crawl spaces and basements, without vapor barriers or with dirt floors, are mold-prone. The “doormat test” detects moisture from concrete slabs without a sub-slab vapor barrier.[9] Some materials, such as polished concrete, do not support mold growth.
HVAC systems can produce all three requirements for mold growth. The air conditioning system creates a difference in temperature, encouraging condensation. The high rate of dusty air movement through an HVAC system may furnish ample food for mold. Since the air-conditioning system is not always running, warm conditions are the final component for mold growth.
In the U.S., sampling and analysis should follow the recommendations of the Occupational Safety and Health Administration (OSHA), National Institute for Occupational Safety and Health (NIOSH), the EPA, and the American Industrial Hygiene Association (AIHA). Types of samples include air, surface, bulk, dust, and swab.[3] Multiple types of sampling are recommended by the AIHA since each has limitations.[15]
How Do Molds Affect People?
“These mold levels were determined based on outdoor exposure to naturally occurring spores in the environment and should not be applied to indoor exposure which may represent an entirely different spectrum of spore types.
A link between other adverse health effects, such as acute idiopathic pulmonary hemorrhage among infants, memory loss, or lethargy, and molds, including the mold Stachybotrys chartarum has not been proven. Further studies are needed to find out what causes acute idiopathic hemorrhage and other adverse health effects.
