Tips for Identifying and Dealing with Mould in Commercial Premises

Mould is a common issue that can pose serious health risks and damage property, making it crucial for businesses in Australia to stay vigilant, especially during certain times of the year. With our humid and rainy seasons, particularly in late autumn and winter, commercial premises can become a breeding ground for mould if not properly managed.

Here's how you can identify and effectively deal with mould in your commercial space.

Identifying Mould in Your Premises

Mould can be tricky to spot in its early stages, but there are key indicators you should be aware of:

1. Musty Odour: A persistent musty smell is often the first sign of mould. If areas of your premises have a damp, earthy scent, it's time to investigate further.
2. Visible Signs: Mould often appears as black, green, or white spots. Check damp, dark, and poorly ventilated areas such as bathrooms, basements, and storage rooms.
3. Health Symptoms: Employees or customers complaining of unexplained allergic reactions, respiratory issues, or skin irritation might be exposed to mould.
4. Water Damage: Any signs of water damage or leaks can lead to mould growth. Look for discoloured walls, ceilings, or floors.

Seasonal Nature of Mould in Australia

Our climate plays a significant role in mould growth, with the following periods being particularly critical on the eastern seaboard:

• Autumn and Winter: Increased rainfall and humidity create ideal conditions for mould. Ensure your premises are well-ventilated and that any leaks are promptly addressed.
• Spring: As temperatures rise, mould spores can become airborne, potentially spreading to new areas. Regular cleaning and air filtration are important during this time.

Dealing with Mould Effectively

If you discover mould in your commercial premises, prompt action is essential. Here are some steps to tackle the issue:

1. Safety First: Equip yourself with protective gear such as gloves, masks, and goggles before handling mould to avoid health risks.
2. Isolate the Area: Prevent the spread of mould by sealing off affected areas with plastic sheeting and turning off HVAC systems.
3. Clean and Disinfect: Use commercial-grade cleaning supplies designed to kill mould. Look for products with mould-killing properties and follow the instructions carefully.
4. Dispose of Contaminated Materials: Items like carpeting, ceiling tiles, and plasterboard may need to be removed and replaced if heavily infested with mould.
5. Control Moisture: Fix any leaks immediately, ensure proper ventilation, and consider using dehumidifiers to keep moisture levels low.
6. Regular Inspections: Conduct routine inspections, especially in high-risk areas, to catch mould early before it becomes a significant problem.

Prevention Tips

Preventing mould growth is more effective and less costly than dealing with an infestation. Here are some preventive measures:

• Ventilation: Ensure adequate ventilation in all areas, especially bathrooms, kitchens, and basements. Use exhaust fans where necessary.
• Monitor Humidity Levels: Keep indoor humidity below 60%. Use air conditioners and dehumidifiers during humid months.
• Regular Maintenance: Regularly inspect and maintain plumbing and roofing to prevent leaks.
• Clean Regularly: Use mould-resistant cleaning products, and keep surfaces dry and clean.
• Use Mould-Resistant Products: Consider mould-resistant plasterboard, paint, and insulation in areas prone to moisture.

While mould is a common challenge in commercial premises acorss our country, especially during the wetter seasons, proactive measures can significantly mitigate the impact. Regular inspections, prompt repairs, and the use of quality cleaning supplies are essential to keeping your premises safe and mould-free.
