The Situation: What the Family Was Facing
The team at Unit444 discovered a horrible scene at the Perth property. A dangerous biohazard situation had arisen in two rooms of the home due to decomposition by biological organisms over weeks. The environment posed serious risks to biological health. The floor, carpet, furniture, and one wall were visibly contaminated. The room was full of flies, which were spreading the contamination. The house was completely unfit for human habitation.
