In its 20 October guidance, Singapore's Ministry of Manpower (MOM) says employers should use tomorrow's PSI air-pollution forecast alongside hourly checks of fine-particle pollution, PM2.5, during the working day. The National Environment Agency (NEA) reported on 19 October that some readings had improved, while smoke remained nearby. A clearer morning therefore does not establish that the air will stay clear all afternoon. OTR's view is that employers able to reschedule tasks, rotate workers and arrange indoor breaks may respond sooner than those waiting for the next daily forecast. We have not measured delays, workers' exposure to pollution or compliance with the guidance. The next useful check is whether outdoor employers record the changes they make when air quality worsens.","links":[]},{"id":"otr-slide-PDF-ae29e122216020b99c26d828-11-detail-2","url":"https://ontherice.org/signals/PDF-ae29e122216020b99c26d828-11/#otr-slide-PDF-ae29e122216020b99c26d828-11-detail-2","title":"The idea, step by step","topic":"evidence","kind":"research","text":"Follow the reasoning from the observations to the proposed result.
