If you suspect that your workplace may have been contaminated, there are some tell-tale signs to look for. First, check for any visible mould growth. Mould can be black, green, white, or brown and can appear fuzzy or slimy. If you see mould growing on any surface, it’s likely that the area is contaminated. Another sign of contamination is a musty or earthy smell. This is often caused by mould or mildew and indicates that there is moisture present, which can lead to mould growth. If you have noticed these signs, it’s important to have your workplace professionally tested as soon as possible. Contamination can cause serious health problems, so it’s vital to take action right away.
