What is Mould?
Mould is an overarching term that’s used to refer to a large group of over 1.5 million different micro-organism spanning everything from yeast, to penicillin and toxic black mould. It can be found both indoors and outdoors, but needs a few key conditions to grow and expand: warmth, moisture and organic matter so it can get to work degrading and decaying.
Mould reproduces by forming a large number of spores, which can become airborne and spread through insects, animals, wind, water and human activity. Risks surface when you inhale significant quantities of particularly harmful types of mould, such as Stachybotrys, Aspergillus and Toxigenic Moulds.
How could it affect me?
The risks of exposure to mould are difficult to evaluate and are directly linked to a person’s health and respiratory issues before exposure. For those with pre-existing conditions, including asthma, allergies or immune-suppressant illnesses, mould can pose a very serious threat. The body recognizes the mould as an allergen which triggers an immune system response. This can lead to wheezing, chest tightness, shortness of breath, difficulty breathing, as well as fungal and lung infections.
Depending on a person’s susceptibility, age, state of health and level of exposure, they could also fall prey to allergy-like symptoms including a runny nose, irritated eyes, congestion, headaches, fatigue and skin rashes.
When am I at risk?
Mould can grow in any number of places where conditions are ripe: in basements, bathrooms, pipes, roofs, construction sites, summer cottages, antique shops or flood sites. You’re especially at risk if you have a pre-existing lung condition or sensitivity to allergies,
but long- term exposure to high mould levels can be risky for anyone - notably for children and the elderly. Mould levels tend to be particularly high in places that have been flooded and in which organic construction materials such as wood or drywall have been left in humid conditions to decay.
Given how widespread and diverse mould can be, government entities have been unable to establish clear safe exposure levels. That’s why we recommend that anyone, especially those with a known sensitivity to respiratory issues wear protective gear whenever they’re coming in direct contact with high concentrations of airborne mould.
What can I do to protect myself?
Control humidity levels
Industry standards recommend that humidity levels go no higher than 50% throughout the day. Air conditioners and dehumidifiers
can go a long way in controlling humidity levels both in homes and across construction sites. The market also offers cleaning products specifically meant to fight and remove mould, which can have a significant impact in areas like bathrooms and basements. Finally, try to avoid carpeting in damp areas like the basement, and remove any previously soaked wood, carpets or upholstery.
