GEORGE TOWN: All schools in Penang have been advised to cut down on outdoor activities if the haze situation worsens.
A circular from the Education Ministry released some time last week stated that all outdoor activities should be reduced or stopped if the Air Pollutant Index (API) readings in the area went above 150.
State Education Department director Datuk Osman Hussain replied in a text message that the ministry had its own standard operating procedure and it had been circulated to all schools in Penang.
Meanwhile, several areas in the northern states were shrouded in haze yesterday.
In Penang, the Department of Environment online portal recorded the API readings in Seberang Jaya 2 at 88 from 6am until 8am and 97at 11am.
The monitoring station at Universiti Sains Malaysia showed 81 at 11am. In Prai, the API was 75 at 11am. In Alor Setar, the API was 86 at 11am.
Over in Bakar Arang, Sungai Petani, the API reading reached the unhealthy level of 103 at 4pm. The reading was 91 at 11am.
An API reading of between 0 and 50 is considered good, 51 to 100 (moderate), 101 to 200 (unhealthy), 201 to 300 (very unhealthy) and 301 and above (hazardous).
The horizontal visibility level recorded by the Malaysian Meteorological Department monitoring stations in Bayan Lepas was 4km while it was only 2km in Butterworth at 8am.
Data from the Asean Specialised Meteorological Centre (ASMC) website showed there were 380 hotspots in Sumatra on Tuesday.
