Before any of Mohamed's team goes into a home to decontaminate it, they are carefully kitted out in their safety suits.

It's Mohamed's responsibility to check they have put on their suits properly and that there are no gaps or exposed areas. Once he's happy, he writes their names on the front and the time. This helps prevent his team mates from working more than the 90 minute limit, which is in place due to the high temperatures and lack of ventilation of the suits, which makes longer shifts dangerous. The safety of his team is key.
