In the summer months, typically between June and August, Singapore is affected by instances of haze. Haze that's produced by the burning of old crop fields in Indonesia. It is a known occurrence, there's not much that can be done about it and life goes on.
Except that this year the haze came on real hard. Beginning mid June and for about 10 days, there were reportedly 200 hot spots burning across Indonesia. Palm oil and other crop farms were set ablaze to clear the land for the next season by reckless farmers. Much easier to set the expansive farms on fire than cut, uproot and dispose. The extensive burning, combined with winds blowing into the area, made the haze in Singapore reach an all time high of 400+ PSI (Pollution Standards Index).

People at higher risk were asked to stay indoors in the air-conditioning if possible. Public and outdoor workers were asked to use a face mask, as needed. The smell of wood burning hung in the air. Eyes itched. People sneezed. Children were luckily on summer holidays and so schools were out. But the majority of people continued on as usual. Public transport, malls, restaurants remained open. Attendance at work was unchanged. The government officials said they were taking steps to take action working with the governing bodies in Indonesia. Singapore offered its assistance to fight the fires and to seed clouds to induce rain fall. But to its residents, the key message was "look out for each other". StarHub, a major cable TV and broadband provider provide all cable channels free over the weekend to keep people entertained as they stayed home. I am sure there are many other instance of people, companies, organizations - just helping out.
As a city-state-country, Singapore is very vulnerable to events in neighboring countries which it has little control over. But the spirit with which the people came together, and the actions the government took to manage the situation was incredible.
So, it was just a haze. Not a major flood or other significant catastrophe. I agree. But how you react to smaller situations is a fairly good indicator of how you would react to a major one.
