Safety Update: Mold - A Workplace Concern?

Mold is a common household word that we typically use to describe decaying or rotting scents or where there is the presence of old food and/or musty humid air. Most of us are well aware that mold is naturally found indoors and out and is a common component of household/workplace dust. A recent celebrity death has created a buzz around the exposure to mold both at home and in the workplace - Should you really be concerned?

Numerous health problems are associated with high levels of airborne mold spores which can compromise the immune system, irritate the respiratory tract and cause allergic reactions. Mold produces and/or excretes toxic compounds called mycotoxins, which under specific environmental conditions, can cause serious illness and even death. It is interesting to note that mycotoxins are also commonly found in mushrooms and are responsible for the illness that follows accidental mushroom poisoning. All types of mold secrete various forms and concentrations of mycotoxins that can potentially be toxic if they are ingested, inhaled and/or prolonged exposure to the skin occurs. Typically, adverse health effects are not common unless exposure occurs in high quantities and over long periods of time.

Mycotoxins have the potential to cause immune system responses that can vary considerably depending on the individual. In those individuals that have compromised immune systems, such as in HIV and AIDS patients, the adverse health effects from exposure to mold can cause serious complications that may worsen their disease and even cause death.

Toxic black mold or stachybotrys, is one of the more common types of mold found in workplaces. It is thought to be present if there is a case of 'Sick Building Syndrome' (SBS) or a combination of ailments and syndromes is prevalent in individuals associated with a specific place of work. SBS is directly related to poor indoor air quality that can include the presence of mold typically created as a by-product of water damaged buildings.

SBS can manifest itself in numerous ways and the range of effects will depend on the level of exposure and the volume of spores inhaled or ingested. Some of the specific effects of SBS and exposure to mycotoxins in black mold include: chronic fatigue, headaches, fever, rashes, chronic coughing, memory loss, nausea, vomiting, hair loss, bleeding of the lungs and nose, pneumonia and even heart attacks.

Detecting mold within a workplace is not always easy because common breeding grounds are not always viewable or accessible. These areas can include: wall cavities, crawl spaces, beneath wallpaper, paneling, and carpet; inside heating and cooling equipment, and air ducts. The tell tale signs of black mold can be a musty, earthy smell, visual stains, rust on fixtures and plumbing, recurring water condensation, recently flooded or damp areas.

While there is no quick remedy for getting rid of mold there are ways to control it. It is always best to contract a trained mold professional to come and inspect any areas of concern. They will take air samples as well as samples from the walls and floor to determine the presence and severity of the mold occurrence. Once the presence of mold is confirmed, it is important to contain the mold and eliminate it. Continuous prevention of future issues of mold growth through moisture and humidity control and overall cleanliness are effective measures in ensuring the problem does not return. Proper mold remediation should always be carried out by a trained mold professional.

Toxic molds can be as risky to your health as any other health and safety issue at your workplace. Be wary of continuous health problems you might be having and be proactive if you suspect mold is present in your workplace.
