What are the challenges you faced at the COVID-19 quarantine zones (aside from the heat), maybe on the personal or mental level?

Perhaps (it’s) going to different sites and having to work with what they provide us. Every site is different in terms of the size, the location of the swabbing area, so you have to go there and make a decision pronto. And take into account the safety of everyone involved -- the MOM staff, the SAF staff, and all the foreign workers as well. So that’s quite a challenge.
