An important first step is to understand what causes mold to spawn in the first place. Mold is a fungus that can grow on practically any surface if the right conditions are present. The catalysts for mold generation are moisture and humidity, which can come from sources such as leaking pipes or rain water. Inattention is beneficial to mold growth. If moisture has collected in an area not ordinarily used, it is a perfect place for the spores to grow and spread. One place not often thought of is the air conditioning units. These can actually spread mold spores by blowing contaminated water into the atmosphere.

The Environmental Protection Agency (EPA) takes the problem of mold growth quite seriously. The Agency advises immediate action if any mold concentration is detected. While it may cause a little discomfort among the students, if the air conditioning is suspected of being contaminated, it has to be immediately shut down. Reducing the chances of mold growth means that any water damage brought on by heavy rain or snow must be addressed within a day or so, and dried up. Some recommend the use of chlorine bleach to stop mold from spreading. It must be remembered that bleach has a level of toxicity and ought to be used under professional guidance. Mold has a difficult time developing in dry places. Any area that is being dried with fans ought to have the fans facing the outside and not towards areas still free of mold.

Mold spores can hitch a ride and school buildings are full of people every day of the school week. Maintaining communication with the occupants will keep them away from contaminated areas and decrease the chances of contact with the spores. There may be structural damage caused by mold, particularly black mold, and there may be mold growth hidden from sight (e.g. behind walls and in crawl spaces). If there is reason to believe that toxic mold is present within the building, all children and staff who have respiratory problems might have to be evacuated from the premises. The EPA recommends that a plan of action be created to deal with the possibility of mold, and recommends that advice from professional mold removers be sought.

Prevention is without a doubt the best means to reduce mold growth in schools. Maintenance staff should be on the lookout for any signs of moisture collecting and clean up any wet areas as quickly as possible. Air conditioning units need to be checked periodically and the drip pans kept free of any water accumulation. Indoor humidity must be monitored and kept low; preferably around fifty percent and no more than that. Routine maintenance needs to include inspection of water pipes. Any that are dripping water must be fixed if not replaced outright. It probably is not reasonable to expect that all molds will be eliminated entirely from a school building; nevertheless, vigilance and immediate action upon notice will keep the mold growth from becoming a serious problem.

Two ingredients come together to form a rather wicked alliance: moisture and time. Floods deliver the primary breeding agent, moisture, into buildings with a full force. The water may cover whole floors and stay for days or possibly even weeks. That length of time is enough for black mold spores to breed and spread. The combination of massive amounts of water and the extended periods of time the flooding stayed is the primary reason for the enormous black mold colonies left in New Orleans after Katrina.

That was, of course, an extreme case. However, flooding obviously creates an emergency that must be carefully dealt with. The immediate problem is an inability to get to the black mold. Flood waters can remain high for extended periods of time and getting into the residence simply might not be possible. Once access can be made, there are still challenges. For instance, the structure of the building may have been weakened by the flood. Safety becomes a concern that has to be dealt with first, as well as getting any excess water out. All of this delays the treatment of black mold colonies and permit even more time for them to spread. When the infestation can be finally be addressed, it may be so extensive as to make clean up a major chore.

Cleaning up black mold contamination after flooding is definitely not a soap and water task. Anyone attempting a clean-up needs to wear protective clothing and rubber gloves. An essential part of the project is to eliminate the moisture that lingers after the flood waters have receded. Fans will help, but care must be taken. Black mold spores can also become airborne. The fan, consequently, must be positioned so as to dry out the room, and yet not blow air into an area not yet contaminated. The whole project may be so daunting that professional help has to be called in. This would meant that the cost of flood clean up becomes an issue of thousands of dollars, and the house may have to be condemned depending on the amount of black mold present.

Is there any protection from the financial damage caused by black mold? The answer is “yes” but it depends on the insurance the homeowner carries. Regular homeowner insurance doesn’t cover black mold damage or removal. This kind of insurance protects against damage happening “accidently and suddenly”. Black mold takes time to grow and does not fit that definition. Flood insurance may cover black mold removal and the Federal Emergency Management Agency (FEMA) does have a national insurance program for flood protection. It does need to be remembered, however, that FEMA insurance policies have a thirty day waiting period before going into effect. Even FEMA insurance has restrictions and exclusions that cover mold repair work. A person ought to examine his or her existing polices, particularly the exclusion clauses, to see if any financial relief is available.

Flooding is a traumatic experience for any property owner and black mold contamination leaves an ugly scab on the emotional wound. Homes in New Orleans were so infested as to be finally condemned and torn down. Flooding creates unhealthy situations and a home or building owner ought to have a flood plan in case of this type of disaster. Checking insurance policies to know if black mold removal is covered, and under what conditions and to what extent, is a logical first objective.

Likely breeding grounds are warehouses and storage areas. Black mold requires moisture and humidity to spawn. Both can be found in warehouses and not necessarily in the basements. The moisture may come from leaking pipes or ceilings. Storage places in a commercial building may have sealed paper boxes. These could get dampened by any number of causes. When humidity due to poor ventilation rises, the boxes become excellent places for the growth of black mold. Kitchens and bathrooms are potential breeding grounds because of the presence of moisture. Black mold spores can also become airborne. As a result, if the HVAC or air conditioning system in a building has moisture contaminated with black mold in it, the spores can actually be sprayed over the facility.

Preventing black mold takes routine, proactive measures. This is a situation in which an ounce of prevention can prevent a pound of a rather expensive cure. The moisture level in the air needs to be controlled to prevent the growth of black mold.  This can be done by increasing the temperature in areas where moisture build up is possible, encouraging quick drying as a result, or bringing the humidity down to acceptable levels (humidity that is more than seventy percent has the potential for black mold generation). The ventilation and air conditioning must be inspected on a routine basis and all damp air filters have to be removed at once. Watery leaks don’t always come from the pipes alone. Damaged gutters and rain spouts can literally pour rain water into the building. These need to be inspected and repaired when needed. The plumbing ought to be routinely checked for leaks, and particular scrutiny must be given to those pipes going into kitchen and bathroom parts of the building.

A plan of action for any commercial building ought to have provisions for testing the environment. Sampling suspect areas for the black mold mycotoxins can give an early warning about the possibility of existing, or growing, contamination. The most commonly used instruments are mold spore traps and the swab test. The former checks the atmosphere while the latter is used to sample surfaces suspected of breeding black mold. They are not interchangeable; one may not be used to test for mold in the other’s area.

Management should be concerned about the existence of black mold for the health of their employees but if that is not sufficient motivation, there is another reason. The Federal Occupational Safety and Health Administration (OSHA) has an interest in the health hazards in a commercial building. Should an employee file a complaint and an OSHA inspection reveal unacceptable presence of black mold, the company may face some serious repercussions.

It need not reach that stage at all. Black mold prevention is little more than customary precaution and inspection. The threat to both the structure and occupants is sufficient to make preventive measures an ordinary part of building administration and maintenance. With an active plan for preventing black mold in place, a commercial building’s management team should be able to keep the place safe from contamination.

Black mold needs a food source on which to grow. This could just as easily be a dinner roll or tomato as it could be the cellulite found in wood. Black mold needs moist areas and a food larder in the basement may offer the environment. Black mold, also known as stachybotrys chartarum, has been found on wet grain used in feeding animals. It has even been suggested that the presence of black mold on various forms of grain caused plague in centuries gone by.

The big difference between black mold found in the structure of a home and black mold found in the pantry is the contact humans have with it. Black mold usually grows in those areas of a building where people rarely go. However, people might accidentally eat food contaminated with black mold. That can cause very serious health problems in individuals, as the same mycotoxins found in the mold of a basement can also be found in mold contaminated food.

Black mold spreads wherever it is found. This means that if a contaminated piece of fruit is placed next to non-contaminated fruit, it will not be long before the other shows evidence of black mold spores. Another problem is that it can be airborne. It is entirely possible for mold spores to spread through the atmosphere of a kitchen, making contact with even more food that is lying about and exposed. The consequences for the health of anybody eating the food is obvious.

The means that in order to prevent black mold in the kitchen are the same as what are used to prevent black mold in the basement. Humidity is the primary medium for black mold and proper ventilation will keep humidity from becoming a problem. Foodstuffs, particularly grain, should be kept in airtight containers that do not allow moisture to get in. Food in the refrigerator needs to be examined carefully and often. If mold is found growing on any piece of food stored in a refrigerator, that item needs to be removed before it comes into contact with other food.  Anything in a refrigerator must to be stored in containers with tight lids. Black mold found on the interior walls of a refrigerator should be washed off as soon as possible.

An easy and economical way to prevent black mold in the kitchen is to change shopping patterns. Too often people buy more food than they actually need, and the excess is stored in places that are prone to infestation. Buying smaller quantities of food that are quickly consumed will minimize the dangers of black mold contamination. Other means of prevention are the periodic cleaning of storage cabinets and checking the refrigerator for any signs of contamination. Black mold forms only when the conditions are conducive. Proper storage, humidity control, and cleaning up areas where food is prepared are the best means of seeing to it that this fungus is not given a chance to generate.

Black mold is not like common dust spores. It can’t be effectively prevented by washing the walls with soap and water. The United State Environmental Protection Agency firmly states that the way to control any mold growth is to control moisture. That makes credible sense as one realizes that moisture is the avenue on which black mold spores grow and spread through a building. Trouble starts developing when the relative humidity inside reaches fifty five percent. A good HVAC system can keep moisture under control, but new filters must be periodically installed to keep mold from developing on them. A humidity meter can help a home or building owner stay alert to the rising humidity levels. Dehumidifiers are also excellent means of keeping moisture levels low.

Rain gutters can literally pour mold-spawning water into a house. Extenders can be purchased for the downspouts, allowing water to be diverted away from the home. Often, routine inspections can uncover potential breeding grounds for black mold. Peeling or splotchy wall paper is possible evidence of moisture buildup, and new wall paper removes the potential problem. Bathroom and ceiling tiles should also be checked and replaced if there are signs of mold forming on them.

There are natural ways to prevent black mold from gaining a foothold and the simplest of these is a basic homemade vinegar spray. The acid found in ordinary apple vinegar makes a space intolerable for black mold to form or grow, and spraying a shower curtain with vinegar periodically will prevent mold from becoming established. Scrubbing an area with borax and water is another good preventive measure. Fabric and rugs may need something else, however, and any mold deterrent ought to be checked for the chemical content before being used on any surface. While there are some very good mold prevention chemical products on the market, a single application is not sufficient. As such, routine applications are recommended for keeping black mold at bay.

It was mentioned earlier that making sure black mold doesn’t gain foothold is worth the expense. As with many household pests, the cure certainly costs more than the prevention, for depending on the extent of the contamination, the price associated with getting rid of this fungus can be steep. Because of the toxins found in some molds, special clothing and protective gear will have to be worn and professionals may have to be called in to deal with the problem. Advanced cases of black mold infestation have resulted in families being force to leave and seek temporary lodging during the clean-up. The worst that can happen is for the house to be condemned and torn down, although this level of severity is fairly rare.

Preventive measures can stop a major disaster from happening. The costs of keeping suspect areas dry are quite reasonable when one considers that insurance companies may or may not cover mold damage. A little effort and prudent investment in the necessary products, equipment, and preventative recommendations for keeping moisture under control can definitely save a lot of grief later, both in terms of structural damage to a home or building, and health complications to the individuals occupying them.

Detection has been made a bit easier by the availability of mold test kits on the market. The kits fall into two categories: air and surface. As the titles suggest, one detects the evidence of black mold in the air (airborne spores) while the other detects mold growing on surfaces such as walls and floors. Mold spore traps are used to discover spores in the atmosphere. It has a sticky slide surface and room air is blown over it using a pump. Particles that are currently in the air stick to the slide and the slide is then examined for the presence of black mold. An air impactor will use a petri dish full of fluid to catch mold spores as they are blown over the open dish. If either test kit does nothing else, both give an idea of the current quality of the air.

A swab test will use a cotton swab or an adhesive tape to collect a sample from a surface suspected of having black mold growing on it. This test doesn’t cost much in terms of time or money, but the tester ought to wear protective gloves to prevent contact with the mold. There are times when the contamination is visibly obvious and the need is to determine how serious the situation is. A bulk sample, material pieces larger than what would be stored in a test tube, are collected and sent to a laboratory for closer analysis by trained professionals. This test does mean that some part of the building will have to be damaged in order to obtain the sample, unless there is some fabric or other material that can be easily collected and sent.

Air and space mold test kits share one thing in common: neither can be used to detect mold in the other’s environment. For instance, a swab test is almost useless in finding black mold spores in a room’s air space, while a mold spore trap isn’t designed to diagnose black mold’s infestation of a wall. Because using only one form of test can give an incomplete picture or scope of them problem, however, it is recommend that both be used to give a full understanding of the degree to which black mold has established itself, and ensure the safest precautions be taken to remove it.

There is something else to keep in mind once a contaminated area has been identified; removal procedures for advanced stages of black mold infestation are not DIY projects. Worst case scenario, these situations can call for a home evacuation and experienced professionals must be called in to solve the problem. If the results of a mold test kit indicate more than superficial evidence of black mold, immediate and technically sophisticated remedies ought to be applied as quickly (and safely) as possible. Mold test kits can help to uncover the level of black mold contamination and this information can then be used to decide what is the best corrective action to be taken.

Mold spores need breeding grounds and black mold, or stachybotrys chartarum as it is known in scientific texts, thrives and multiplies in the damp, moist areas of a building. These are spaces with high levels of humidity and perhaps small puddles of water up against the walls. It doesn’t take long for black mold to establish itself in opportune places. The basement is a common place for mold growth, but the same is true for crawl spaces and attic areas under a leaky roof.

Moisture is the breeding ground but the greatest reason why a black mold problem might get worse is neglect. The Occupational Safety and Health Administration (OSHA) candidly warns that any wet area in a building must be dried within 48 hours of being detected. The longer the delay, the better the chances of black mold generation. Leaky pipes have been known to be a cause of dampness, but too often this is a problem that goes unattended and leads to even greater complications. Ventilation keeps the humidity down and circulating air will help keep a place dry. That’s true if the ventilation system is adequately maintained. However, air ducts left unattended can collect small amounts of water and will effectively blow moisture all over the place and the droplets may include black mold spores.

Not noticing the all too obvious signs of black mold infestation enlarges the problem. An example is the musty odor that is simply tolerated and never investigated. The smell is a sign of mold developing. If this odor is noticed when the air conditioning is on, it may mean that there is mold buildup within the unit. That, in turn, suggests that the HVAC system may actually be spreading black mold spores. Warped wood is another sign of moisture building up inside the fibers. Left unattended, the wood becomes a base for black mold to not only develop, but also spread along the panels and planks to infest whole rooms. Small amounts of mold in plain sight may be signs of less visible and more extensive colonies. If the signs are ignored, the danger and its ultimate consequences grow ever larger.

Clearing up the problem once does not mean it goes away permanently. Black mold can be controlled and prevented with a little vigilance and routine inspections. Damp areas must be dried as quickly as practicable and HVAC systems should be checked for any signs of moisture buildup. Noticeable signs such as warping and musty odors must never be ignored. Some precautions may seem tedious or time consuming, but they can prevent black mold from getting out of hand. The last thing anyone needs is to have the problem fester to the point where the only solution is to have the infected building demolished.

Black mold grows where there is moisture and humidity. A warehouse is a probable site for black mold to spawn because of the construction of the building. Moisture, the breeding ground for black mold, can drip into the building from poor drainage from the gutters or, if the building has a flat roof, water could collect and gradually seep into the interior roofing. A prime place for mold growth is company storage areas. Proper ventilation can keep the humidity down, but the storage facility may not have air conditioning or fans, creating the right atmosphere for mold to grow and eventually spread. Inadequate ventilation equipment can be just as bad, as damp air ducts can actually be an agent for spreading mold spores. Paper and other business related materials may be in closed shelving or cardboard boxes. Should these get wet for any reason, they are potential mediums for mold for as well.

A few precautions can make a workplace less susceptible to the risk of black mold. For example, storing paper and files in shelves that have plastic wire instead of solid cardboard permits the air to circulate among the sheets and keep the contents fairly dry. The roof of the building should be routinely inspected for standing water and inspection of the rain gutters is a very good precaution. Air conditioning in a warehouse doesn’t have to be frigid either; just cool enough to keep humidity down and strong enough to keep the air moving. Moving air at less than humid temperatures, by the way, helps prevent moisture from building up. A business owner shouldn’t hesitate to ask for help from the insurance company whose property/casualty coverage protects the premises. A loss control representative can inspect the property with the intent of making recommendations to prevent black mold.

Any suggestion given by the professional should be followed immediately, as the longer the problem goes unnoticed (or uncared for), the bigger the threat can become. Black mold health risks to workers can also draw unfavorable attention from the Occupational Safety and Health Administration (OSHA). The uncontrolled presence of mold in a workplace is a serious violation of OSHA housekeeping standards. As such, complaints filed by the employees themselves can lead to expensive litigation, in addition to any health and/or building repair costs.

OSHA does offer guidance to help business owners recognize potential breeding grounds for mold in the workplace, as well as what the clues are for identifying the presence of mold in a room or building. As mentioned, moisture creates the conditions necessary for black mold to grow and wet or damp areas need to be dried as quickly as possible. OSHA suggests that if a work area has been wet for forty-eight hours or more, the space should be dried immediately to protect the health of the workers. Careful monitoring of the area for weeks or even months after is also a good idea, as the initial dampness may have been enough for mold to take hold.

Both mold and mildew are products of moisture. The most common forms of mildew can be found in the garden. Powdery mildew is well known to gardeners and so, too, is downy mildew. Mildew in the house grows primarily on fabric but can also be found on shower curtains and in laundry areas. It also grows inside quite rapidly and has a very nasty odor to it. Mildew is not necessarily a hazard to health; however, if inhaled, mildew can cause headaches, coughing, and other forms of physical discomfort. It is not by itself life threatening.

Mildew is a form of mold, but that does not mean that mold is a form of mildew. The biggest difference between mold and mildew is that black mold, also known as stachybotrys chartarum, can cause serious illness. This fungus is the source of a trichothecene mycotoxin known as Satrotoxin-H. Airborne black mold spores can generate severe physical reactions if breathed in. This pathogen can be such a threat to health that homes heavily infested with black mold need to be evacuated and radical means, including demolition, have to be used.

Mold also has the potential of weakening the structure of a building as the spores eat into wood and other building materials. Once identified, neither mold nor mildew is something to be ignored. Keeping moisture under control helps, because both need water as a medium for growth. While mildew, like mold, must be controlled, it does not require remedies as extreme as those used to control black mold. Mildew control can be a DIY project for a home or building owner and there are a number of products available on the market that anyone can use to get rid of this household nuisance. Mold, however, is oftentimes an entirely different matter.

Black mold needs to be dealt with immediately once it has been detected, and removal is not always a simple household chore. The harmful pathogens generated by this fungus mean that simply washing the blighted area may be dangerous. Depending on how invasive the infestation has become, black mold may require professional mold removal to eliminate it from the premises. Because it is often difficult to determine the level of severity of the contaminated area, especially to the untrained person without more sophisticated equipment, it is typically best to air on the side of caution when deciding whether or not to utilize professional help; especially when the risks are severe.

Prevention is always less expensive than the cure, and both mold and mildew growth can be discouraged with simple household appliances, such as dehumidifiers, fans, and effective ventilation systems. Routine inspection of the more common areas for mold to thrive, such as basements, bathrooms, and attics, can often stop the problem before it turns into a bigger problem. While there is a significant difference between mold and mildew, what they have in common are the negative effects created by their presence in a home. Even if the initial warning sign is nothing more than a musty odor, mold and mildew make a house less comfortable and potentially harmful to be in. Failure to do anything can lead to further problems for the health of the hearth and the people living there.

Black mold thrives on damp and wet areas. As such, being able to control the amount of moisture in a house is a definite step in the right direction. There are a number of relatively simple ways to keep mold breeding moisture to the barest minimum. For instance, a bathroom’s wet atmosphere is easily controlled by opening a window for a few hours during the day. A ceiling exhaust fan can also be used to reduce humidity.

Like the bathroom, the basement is another area where black mold often collects. Because of this, the house’s drainage system needs to be examined for the possibility of rain water seeping into the lower levels of the home. If this does happen, the gutter systems may need repair or extenders added on to the downspouts to direct water away from the home.

Air flow is important as a drying medium and improving the circulation in a room can be improved by the use of a ventilation system and even simple floor or wall fans. The bathroom, for instance, is a prime location for mold to fester. Fortunately, most bathrooms have ceiling fans installed, which suck up the moisture caused by the steam from the hot shower. As such, it’s always recommended to turn this fan on when showering or leaving hot water on for extended periods of time. The floor of the basement can be heated by means of underfloor heating and that will keep the area dry, removing or at least reducing potential black mold breeding areas. Areas prone to spring flooding benefit from the installation of sump pumps that prevent water from reaching levels above that of the basement floor.

De-humidifiers have been recommended for controlling internal moisture. These are particularly valuable in houses where there is no air conditioning. The size of the de-humidifier is an important consideration. The appliance has to be large enough to keep a room relatively dry and still be energy efficient. A final means of eliminating potential breeding areas for black mold is using efficient storage strategies. Periodically airing out storage closets and making sure that damp things are not allowed to collect on the floor are good ways to control moisture. Open shelving that uses plastic wire is excellent because it permits air to better circulate among stored items than solid shelving. All of the above can help prevent black mold from gaining a foothold in a house.

Of course, it isn’t always possible to keep a house as dry as a bone, particularly in humid climates. Keeping moisture under control must be combined with routine inspections of places where black mold is likely to proliferate (e.g. bathrooms, basements, under kitchen sinks, etc.). Further, it can never be assumed that this fungus, once removed, will never come back. Still, if a homeowner is able to practice regular and proper due diligence, the odds are in that person’s favor that black mold will never become a problem that gets out of control.
