Health Advisory for General Public and Workers

Note: The advisory issued each day by NEA on forecast haze levels will be based on the PSI. However, if PM2.5 levels warrant a higher-level advisory, a higher-level advisory will be issued.

** Prolonged = continuous exposure for several hours

*** Strenuous = involving a lot of energy or effort

^^ The use of N95 mask increases the effort in breathing and may cause discomfort, tiredness or headache. For most people this is not serious.

However, as some elderly people, people with chronic lung disease, heart disease or stroke, and women in the 2nd and 3rd trimesters of pregnancy may already have reduced lung volumes or breathing issues, they should stop using a N95 mask if they feel uncomfortable. They should consult their doctor as to whether they can use the N95 mask.

Women in the 2nd and 3rd trimesters of pregnancy should not use the N95 mask for more than a short duration each time.

N95 masks are not certified for use in children, so children should remain indoors as much as possible.
