Protection for the Vulnerable Against the Haze


Sarah Peddie

As the haze over Singapore continues, healthcare institutions and nursing homes are doing all they can to protect people who may be vulnerable to it. 

Wards without air conditioning have been given air purifiers and screens to prevent the inflow of the haze. 

What is haze?

Haze is an atmospheric phenomenon in which dust, smoke and other dry particles obscure the clarity of the sky. 

Over the past few weeks, Singapore has been covered with haze which has made the condition of the air unhealthy. 

Last weekend, the city state held its annual Formula One race. The air quality got worse over the weekend as smoke from the surrounding region blew in.

Many hospitals are trying their best to protect patients from the haze. In Changi General Hospital in Simei, for example, their ventilation systems are fitted with high-efficiency particulate air filters. The filters are fitted to trap harmful particles in the air.

The hospital is also monitoring the number of patients with respiratory-related conditions. Patients who have medical conditions that make them vulnerable to the haze have received suitable respirators for support.

As for nursing homes, they have also taken measures to battle the haze and keep their senior citizens safe.

Steps are taken to make sure patients in non air conditioned rooms are protected when the Pollutant Standards Index (PSI) exceeds 100.

What is PSI?

The Pollutant Standards Index is a type of air quality index, which is a number used to indicate the level of pollutants in the air.

However, the city state looks like it is set to get some relief from the haze as thundery showers are expected during the week.

The National Environment Agency (NEA) gave an update earlier this week saying that the PSI is also likely to drop from the low end of unhealthy to the high end of moderate.
