Molds, Allergies and Indoor Air Quality: A Crucial Issue for Companies

Molds: an invisible enemy

Molds are microscopic fungi that proliferate in damp, poorly ventilated environments. They can appear following water damage, water infiltration, capillary rise, etc. They produce small reproductive structures known as spores or conidia, which can disperse in the air and settle on various surfaces. Offices, warehouses and manufacturing areas are particularly vulnerable, especially if humidity levels are not properly controlled. They can also be present in ventilation ducts (Air Handling Units) and be dispersed into offices and other workspaces by the airflow.

Impact on employee health

Mold exposure can cause a variety of health problems, including allergic reactions such as sneezing, coughing, itchy eyes and skin irritations. For employees suffering from asthma or respiratory disorders, mold can aggravate symptoms and induce attacks, affecting their ability to work effectively. All these situations can contribute to work-related discomfort, loss of motivation and concentration difficulties. This discomfort can give rise to complaints to the CHSCT or Human Resources, and a deterioration in the general atmosphere within the company.

Focus on the inflammatory reaction

The physiological reaction that occurs in allergy sufferers can be an inflammatory reaction. This is a reaction to the immune system, which has set up tools to protect itself from foreign bodies, including mold spores. Foreign bodies contain antigens, the specific signatures of each microbe. When microbes are present on the human body (skin, mucous membranes, digestive tract), the immune system recognizes the microbe and uses a set of tools to protect itself (antibody, T or B lymphocyte…). In some cases, this protection is disproportionate to the aggression, and the body generates an excessive immune response, leading to alteration of normal tissues, hence the allergic reaction. Each person has a different immune response, depending on predisposition, prolonged contact with some molds…

Economic impact

Mould-related health problems can have significant economic repercussions for companies. Repeated absences of employees due to chronic illness or a feeling of malaise at work, lower productivity through reduced attention span, staff shortages and possible sick pay can represent significant costs. Moreover, a healthy working environment is a key factor in attracting and retaining talent.

Prevention and control strategies

To ensure good indoor air quality and minimize mold-related risks, companies need to adopt proactive measures:

• Effective ventilation: Ensure adequate ventilation in all workspaces, especially in humid areas such as break rooms and restrooms.
• Humidity control: Use dehumidifiers and keep humidity levels below 60%.
• Indoor air audits: Carry out regular audits to assess air quality and identify areas at risk.
• Regular maintenance: Carry out regular inspections and repairs to prevent water leaks and infiltration.
• Training and awareness: Train employees to recognize signs of mold and report any potential problems.

Conclusion

For companies, managing mold and ensuring good indoor air quality are essential elements in ensuring the health and well-being of employees, while optimizing productivity and reducing the costs associated with health problems. By adopting preventive measures and remaining vigilant, companies can promote a healthy and attractive working environment for all.
