1. What is PSI? How is the index measured? What is the meaning of the index?
PSI stands for 'Pollutant Standards Index'. It is an index to provide accurate and easily understandable information about daily levels of air quality.
PSI is computed based on 24-hour average of PM2.5 concentration levels, among other pollutants. PM2.5 is the dominant pollutant during haze episodes.
The ambient air in Singapore is monitored through a network of air monitoring stations located in different parts of Singapore.
The monitoring stations measure concentration levels of particulate matter (PM10), fine particulate matter (PM2.5), sulphur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), and carbon monoxide (CO). These six pollutant parameters determine the PSI.
The PSI value gives an indication of the air quality as shown:
2. How did Singapore arrive at the new PSI? What were the key considerations?
We looked at the air quality reporting systems adopted by various countries including those which incorporated PM2.5 in their index, such as those used by Australia (New South Wales), Canada, China, the European Union, Hong Kong, UK and USA.
There are no international guidelines on how air quality indices should be computed. Countries adopt different index systems based on their local needs and circumstances. In the case of Singapore, we have, since August 2012, made available 24-hour PM2.5 concentration levels together with the PSI readings. PM2.5 is an important component of air quality and its health impact is of concern to us.
As part of Singapore’s regular review, and to better report air quality, NEA has further transited to an integrated air quality reporting system which incorporates PM2.5 into the PSI, and will now reflect a total of six pollutant parameters. The new index also addresses concerns of having to track two figures (PSI and PM2.5).
3. What is the difference between the old PSI and the new PSI?
The new PSI incorporates PM2.5 into the PSI, along with the existing five pollutant parameters. Therefore the six pollutant parameters tracked in the new PSI are: sulphur dioxide (SO2), particulate matter (PM10), fine particulate matter (PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO) and ozone (O3). PM10 refers to particulate matter that is equal or smaller than 10 microns in diameter and includes PM2.5 particles which are equal or smaller than 2.5 microns.
4. Will there be a difference in the range of PSI numbers we see? Why are there more Moderate days than Good days with the new PSI? Will the new PSI show a different range of numbers? Was the previous PSI inaccurate?
Singapore may seem to experience more days with air quality in the Moderate band (i.e. PSI 51 to 100) than before. This does not mean that air quality in Singapore has worsened. Instead, this is due to the incorporation of PM2.5 concentration levels into the index and the more stringent bandings for PM2.5.
5. What is the difference between the 3-hour PSI then and the 3-hour PSI now?
Previously, during haze episodes, the 3-hour PSI was calculated based on the average of PM10 readings over the last 3 hours. Under the new PSI system, the 3-hour PSI is calculated based on PM2.5 concentration levels, as the PSI incorporates PM2.5 and PM2.5 is the main pollutant of concern during periods of smoke haze.
6. For the new 3-hour PSI, is there a difference in the range of numbers we see given that it is now based on PM2.5 rather than PM10?
We expect to see higher 3-hour PSI readings, even though air quality remains unchanged. This is due to the more stringent bandings for PM2.5 than for PM10.
7. If so, what is the difference like and which categories of air quality do they fall into?
We do not classify air quality into the different categories based on the 3-hour PSI readings as those categories are based on the averaging period of the concentration levels of the respective pollutants, which is 24 hours in the case of PM2.5 and PM10.
8. What is the difference between the PM2.5 in the new 24-hour PSI and the new 3-hour PSI?
For PM2.5, the new 24-hour PSI reflects the PM2.5 concentration levels averaged across 24 hours. The new 3-hour PSI reflects the PM2.5 concentration levels averaged across 3 hours.
9. The PSI readings only show historical data. How can I plan for the days ahead?
During haze episodes, NEA will provide an air quality forecast for the next 24 hours. NEA will look at all relevant factors, including weather conditions, in determining this forward projection.
10. Between the new 24-hour PSI and the new 3-hour PSI, which one should I refer to when I want to plan my next course of action?
To date, the vast majority of studies on the health effects of short-term exposure to PM have used the 24-hour measurements. These studies do indeed demonstrate good correlation of health effects with 24-hour PM averages. In view of this, the health advisory in Singapore takes reference from the 24-hour PSI.
Although there have been recent studies on sub-daily or shorter PM2.5 exposure, the evidence of these studies do not constitute a sufficient base of evidence for the development of health advisories.
People can use the 3-hour PSI or 1-hour PM2.5 concentration levels to make adjustments to their daily activities if they wish to do so. For example, if the 3-hour PSI is high, you may wish to postpone strenuous outdoor activities such as jogging.
11. Why is it that the 3-hour PSI readings during the smoke haze periods is at times low even when the visibility is poor?
The 3-hour PSI is based on PM2.5 concentration levels averaged across 3 hours. As the hour to hour concentrations may be volatile, the 3-hour PSI may not correspond to what you may observe at that specific instant.
12. How are the five regions (North, South, East, West and Central) for PSI determined and which region PSI should I note?
You should first note your location as the five regions are based on town centres/areas. A general guide of the town centres/ areas within each of the five regions is listed below. If your location is not listed, please use the region closest to you.
NEA also provides haze situation updates and advisories during a haze period. The advisories are posted at www.haze.gov.sg. You may use the advisories to plan your activities.

13. Which index are the health advisories based on?
The health impact of air pollution is related to concentration levels of pollutants, the duration of exposure, as well as the health status and level of activity of the individual. The health advisory is based on the 24-hour PSI (which incorporates the 24-hour PM2.5 concentration levels) as scientific and epidemiological studies on the health effects of particulate matter have been based on this duration of exposure.
The 3-hour PSI is only an indicative measure. There are currently few studies on the health effects of short-term exposure to PM concentration levels.
Ministry of Health: www.moh.gov.sg/haze
14. What would the public use the 1-hour PM2.5 concentrations for?
The 1-hour PM2.5 concentrations reflect the PM2.5 levels averaged over one hour, and can give you an indication of the current air quality. However, the 1-hour PM2.5 concentration levels can be volatile and tend to fluctuate over the day especially during periods of transboundary haze.
Short-term fluctuations will also be very heavily influenced by weather conditions. For example, there could be a short period of transiently high PM2.5, only to improve rapidly in the next one to two hours. Therefore, if you wish to use the 1-hour PM2.5 concentration, it is best used as a guide to adjust your immediate activities
During haze episodes, health advice will be based on the 24-hour PSI. It is a better reflection of the total exposure of an individual to PM2.5 levels, and scientific and epidemiological studies on the health effects of particulate matter have been based on the 24-hour duration of exposure.
15. What are some practical tips for households to reduce exposure to haze particles at home?
During haze episodes, the air pollutant of concern is mainly haze particles. Some practical tips to reduce indoor exposure to haze particles at home include:
How to choose an air purifier:
Some air purifiers are labelled with a Clean Air Delivery Rate (CADR), which has three CADR numbers - one each for smoke, dust, and pollen. The smoke CADR is the most appropriate for haze pollutants. An appropriate air purifier should have a smoke CADR number that is at least 3 times the volume of the room in cubic metre, or 1/12 of the volume of room in cubic feet. A larger CADR number means faster cleaning in an enclosed room.
There are many effective air purifiers without CADR rating in the market. Users should obtain from the manufacturer information that backs any claim on efficiency of removal of fine particles.
http://www.haze.gov.sg/haze-updates/list-of-portable-air-cleaners-and-suppliers provides a list of portable air purifiers and suppliers for reference.

16. Can we conduct cloud seeding in Singapore to disperse the smoke haze?
Cloud seeding attempts to artificially induce rain by implanting clouds with suitable particles. The seeding particles serve as condensation or ice nuclei to induce formation of more water droplets or ice crystals in the cloud. However, there are no reliable means to validate the effectiveness of cloud seeding in Singapore.
Cloud seeding requires existing clouds as it cannot generate rain out of thin and dry air. During dry seasons, cloud seeding is less effective due to the lack of suitable clouds for seeding. The small size of Singapore and the variability of winds also mean that the induced rain, if any, may not fall directly over our island. Rain may also provide only temporary relief as the smoke haze would continue to be blown toward Singapore by the prevailing winds, should the fires in the region continue to persist.
17. Why is there a burning smell during the haze period? Why is there sometimes a strong smell even though the PSI is low?
Transboundary haze affecting Singapore mainly arises from forest and peat fires in the region. Besides generating smoke particles, vegetation and peat land fires also generate a complex mixture of gases which cause an acrid burning smell.
The smell is usually, but not always, accompanied by an increase in the PSI/ PM2.5 readings. The occurrence of some fires in your vicinity, may also contribute to the burning smell, which was the case on a number of occasions during the recent prolonged dry spell.
18. What are the key air pollutants of concern?
The key air pollutants of concern include particulate matter (PM), sulphur dioxide, ozone, nitrogen dioxide and carbon monoxide. Short term exposure (i.e. continuous exposure to unhealthy daily average PSI levels over a period of a few days) to these air pollutants can cause respiratory symptoms and aggravate existing heart or lung disease. Exposure to particulate matter and sulphur dioxide may also cause irritation of the eyes, nose and throat in healthy individuals.
In Singapore, the main air pollutant in the event of haze is particulate matter (PM).
19. What is the short term effect of the haze on my health?
Among healthy individuals, short term exposure (i.e. continuous exposure to unhealthy daily average PSI levels over a period of a few days) to high levels of haze particles may cause irritation of the eyes, nose, and throat in healthy individuals. Such irritation resolves on its own in most cases.
Haze particles can affect the heart and lungs, especially in people who already have chronic heart or lung disease e.g. asthma, chronic obstructive pulmonary disease (COPD), or heart failure.
There may be up to 1-3 days of time between exposure to haze and health effects/ symptoms.
20. What are the long term effects of the haze?
Singapore is not affected by the haze throughout the year. Any exposure is short-term in nature (i.e. continuous exposure to unhealthy daily average PSI levels over a period of a few days) and such exposure may vary from year to year. As international studies are based on long term exposure to air pollution, there is little robust data on the longer-term effects of short-term exposure to haze like the pattern seen in Singapore.
Studies have shown that persons living overseas with continuous exposure over several years to high ambient pollution from fine particles (i.e. particulate matter 2.5 (PM2.5); particles smaller than 2.5 micrometers), may have a higher risk of (i) cardiovascular effects, such as heart attacks, (ii) reduced lung development, as well as (iii) the development of chronic respiratory diseases, such as asthma, in children.
21. What is the revised Pollutant Standard Index? How is it different from PSI reporting last year?
The new, integrated air quality reporting index incorporates PM2.5 in addition to sulphur dioxide (SO2), particulate matter (PM10), nitrogen dioxide (NO2), carbon monoxide (CO), and ozone. Previously, health advisories issued by the Government were based on both 24-hour PSI and 24-hour PM2.5, whichever was worse. Under the new air quality reporting system, the health advisory will be based on the new 24-hour PSI as it now directly takes into account PM2.5.
22. Why is the health advisory based on 24-hour PSI, rather than the 3-hour PSI?
Health impacts are related to concentrations as well as duration of exposure, in addition to the health status and level of activity of the individual. The health advisory is based on 24-hour PSI (incorporating 24-hour PM2.5 concentration) as scientific and epidemiological studies on the health effects of particulate matter have been based on these measurements.
23. Which groups of people are more sensitive to haze?
In general, children, elderly, and people with chronic lung disease, heart disease are more sensitive to the health effects of haze, and should adopt the preventive measures in the MOH health advisory when air quality is poor. Individuals are advised to consult their doctor should they develop breathing difficulties. In addition, it is advised that pregnant women reduce exposure to haze for the health of their unborn baby.
24. What is MOH’s advice to the public?
The public is recommended to adhere to the MOH haze health advisory. In most cases, it is still safe to carry on with outdoor activities. However, do drink plenty of water to stay well hydrated. Individuals with existing chronic heart and lung conditions should ensure that your medications are on hand and readily available.
Nonetheless, please note that each individual’s reaction to pollutants may vary, and the amount of physical activity or exertion that can be performed differs according to an individual’s health status or physical capacity. Should you encounter symptoms or discomfort, please take additional measures to prevent further exposure.
Although the general advice to the public when the air quality is good or moderate (PSI≤100) is to maintain normal activities, vulnerable persons, especially those with chronic heart and lung conditions, who develop symptoms or feel unwell should seek medical attention promptly.
25. Which haze index should employers monitor so as to decide what measures to take to protect their workers?
Employers should refer to the 24-hr PSI forecast on the NEA website, as well as the updated health advisories on the NEA website (www.nea.gov.sg) or the Haze website (www.haze.gov.sg).
The impact on one’s health is dependent on the quality of air, duration of exposure, and one’s health conditions. Employers can take reference from MOM’s guideline to employers, available on MOM’s website (www.mom.gov.sg/haze) and the Haze website (www.haze.gov.sg) for general measures to minimise or mitigate the effects of haze on their employees. Additional measures specific to the work requirements and health conditions of the employees would have to be instituted based on the risk as assessed by the employers.
26. What other workplace measures can companies consider or do to mitigate the impact of the haze on workers?
All employers should carry out proper risk assessments of their various work activities and implement appropriate measures, to ensure that the risks identified are minimised or mitigated.
Depending on the air quality, employers should first find ways to reduce or avoid prolonged or strenuous outdoor work. Risk assessments, taking into account the impact of the haze, individual employee’s health, work demands and fatigue, etc, must be conducted and risk mitigating measures adopted. Examples of such measures include:
If prolonged or strenuous outdoor work is unavoidable, an employer who requires an employee to do so due to extenuating circumstances, is strongly urged to provide masks. Employees who need to wear masks / respirators should be fit-tested to ensure good fit. Employers should ensure sufficient stock of masks / respirators for these employees, and conduct training and supervision to ensure correct usage. Masks should be changed when soiled/physically damaged or when the wearer finds it hard to breathe. Elderly and pregnant employees as well as those with chronic heart/lung disease should consult their treating doctors on the usage of masks.
Reference should be made to the Singapore Standard SS 548:2009: Code of Practice for Selection, use and maintenance of respiratory protective devices. Employers are strongly encouraged to adopt a flexible and enlightened approach in implementing flexible work arrangements for all staff, especially susceptible employees, such as the elderly, pregnant and those with chronic heart or lung illnesses. Examples of flexible work arrangements include telecommuting.
If their employees feel unwell and wish to rest at home, employers are encouraged to be flexible in allowing them to take their leave. For employees who have used up their annual leave/sick leave entitlements, employers could consider granting them advance leave or other leave arrangements. In such situations, the employees’ wages should not be deducted.
27. MOM’s guidelines advise employers to institute regular rest breaks during the haze. How long would be a sufficient time for each break?
MOM’s guidelines provide general measures that employers can take to mitigate the risks their employees face in a haze situation, and is not meant to be prescriptive.
Employers should carry out a proper risk assessment of their various work activities and implement appropriate measures (such as identifying appropriate rest periods) so as to ensure that the risks identified are minimised or mitigated.
28. What should an outdoor worker do if an employer does not heed the advisory on the haze situation?
Workers should first raise their concerns to their supervisor, HR department and union representatives. If no action has been taken, workers can call the MOM Contact Centre at 6438 5122 or visit http://www.mom.gov.sg for general advice
If there are significant safety concerns on outdoor work during the haze situation, workers can call the MOM Occupational Safety and Health Hotline at 6317 1111 or email MOM_OSHD@mom.gov.sg.
29. Who can workers turn to if there are employer and employee disputes regarding the haze risk assessment?
30. What penalties can MOM impose if employers do not follow MOM's guidelines?
Under the Workplace Safety & Health Act (WSH Act), employers have a duty to protect their employees’ safety and health at work.
In situations where haze poses risk to the safety and health of workers and measures have not been taken to mitigate those risks, either by adopting measures suggested in the advisory or other alternative mitigation measures, MOM may order the affected work to stop. If any person (individual or corporate bodies) subsequently fails to comply with a stop work order, under the WSH Act he shall be liable on conviction to a fine not exceeding $500,000 or to imprisonment for a term not exceeding 12 months or to both.
Our inspectors will be looking out for employers who disregard the safety and health of their workers, especially those performing strenuous and prolonged outdoor work.
31. If an employee suffers injury or illness while working in hazy conditions, will the worker be eligible for work injury compensation?
Under the Work Injury Compensation Act (WICA), an employee who sustains an illness/injury arising out of and in the course of employment is eligible to claim work injury compensation from his employer.
Employers should notify MOM (through the iReport tool on the MOM website) if any employee has sustained an illness/injury due to working outdoors during the haze. For cases where the employee is able to recover over time and resume work without permanent ill effects, employers should pay any medical leave wages and medical expenses due directly to the employee.
N95 masks are not needed for short exposure, like commuting from home to school or work, travel from bus-stop to shopping mall. N95 masks are also not needed in an indoor environment.
A healthy person who has to be outdoors for several hours when the air quality is in the hazardous range (PSI >300) may reduce exposure by wearing a N95 mask.
People with chronic lung or heart disease, elderly, and pregnant women should avoid or minimize outdoor activity when the air quality is very unhealthy (PSI > 200). If they have to be outdoors for several hours , they may reduce exposure by wearing a N95 mask.
You should take a break from using a N95 mask if you feel uncomfortable. Elderly, pregnant women and people with severe lung or heart problems who have difficulty breathing at rest or on exertion should consult their doctor as to whether they should use the N95 mask.
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.
32. Is the N95 mask an adequate protection against haze? Does it protect against PM2.5?
N95 masks work only if there is a good fit with the face of the wearer. This way, most of the air that the wearer breathes in has to go through the filter and not through the gaps between the mask and the wearer’s face. Haze can contain fine particles that are 2.5 microns or smaller (PM2.5), and studies have shown that N95 masks do provide good protection against particle pollutants as they are at least 95% efficient against fine particles that are about 0.1 – 0.3 microns.
33. What are the effects of wearing a N95 mask?
The use of N95 masks increases effort in breathing. For some people, the use of N95 mask may cause discomfort in breathing, tiredness or headache. This may be due to the mask causing increased resistance to breathing, and a reduction in the volume of air breathed. For most people this is not serious.
However, some elderly people, people with lung or heart conditions, and women in the later stages of pregnancy may already have reduced lung volumes or breathing issues.
34. How do I get a mask?
Masks are available at major pharmacies and supermarkets, such as Unity, Watsons, Guardian, Cold Storage, Giant and Fairprice. The national stockpile of N95 masks may be released to the major pharmacies and supermarkets if more are needed.
Employers of workers who are required to work outdoors for prolonged period are encouraged to maintain a seven-day stock for immediate response. Procurement of additional masks can be made through the major pharmacies and supermarkets.
35. Are there different types of N95 masks in the market?
There are different brands of N95 masks in the market which have the same functionality. They come in different colours, shapes and sizes. Please see also Annex A.
36. What are EN-149: 2001 masks? Are they equivalent to the N95 masks?
EN-149 is one of the European Standard for masks while N95 masks are certified by the US National Institute for Occupational Safety and Health (NIOSH). Both types of masks are designed to reduce wearer’s respiratory exposure to airborne contaminants such as particles, gases or vapours.
The EN-149 masks are classified in three classes depending on the ability to separate air-borne particles:
Separation ability at 95L/min airflow
Filter separates 80% of airborne particles
Filter separates 94% of airborne particles
Filter separates 99% of airborne particles
FFP2 masks that meet the EN-149 standard are the closest to N95 masks in the ability to filter particles.
37. How would members of public know if the N95 or other types of masks meet safety and quality standards?
A NIOSH-approved mask is certified by the US National Institute for Occupational Safety and Health (NIOSH) to have 95% filter efficiency. A NIOSH-approved respirator has the following information printed on its packaging:
A list of NIOSH certified N95 masks is available on NIOSH’s website: http://www.cdc.gov/niosh/npptl/topics/respirators/disp_part/n95list1.html
Please also see Annex B for some examples.
EN149 is the European Standard for respiratory mask designed to reduce wearer’s respiratory exposure to airborne contaminants such as particles, gases or vapours. Masks are classified in 3 three classes depending on the ability to separate air-borne particles according to the FFP (Filtering Face Pieces). An European standard certified mask will have the following text printed on it:
38. How does a consumer choose which mask to purchase?
Both the NIOSH-certified N95 masks or the EN-149 masks are designed to reduce wearer’s respiratory exposure to airborne contaminants such as particles, gases or vapours. Consumers should perform a fit check to ensure a good fit.
39. How do I learn to fit my N95 mask?
For best effect, N95 masks need to be fitted properly for each user. To check for proper fit, please check that the available mask is appropriately sized and covers the nose and mouth comfortably without leak.
The HPB website has a step by step guide on how to wear it N95 masks properly. See http://hpb.gov.sg/HOPPortal/health-article/HPB051226#ANNEXD
The use of N95 masks to filter out pollutants in the air is not identical to the use of N95 masks for infection control in a healthcare institution during a disease pandemic situation. For use during a haze incident, even if the mask is not perfectly fitted, it can still be useful in filtering out pollutants for those who need to wear it.
40. How do I wear a mask?
To learn how to put on a mask properly, the HPB has an info graphic on how to wear a mask on their website http://hpb.gov.sg/HOPPortal/health-article/HPB051226#ANNEXD. Please see also Annex C.
41. Can I reuse my N95 mask?
You can reuse your N95 mask. It should be changed when it gets soiled or distorted in shape. It should not be shared.
42. Are surgical masks useful?
Normal surgical masks can protect the wearer’s nose and mouth from irritants in the air but are not effective in filtering fine particles.
Individuals with acute respiratory infections may wish to wear a surgical mask to prevent spread of infection.
Individuals may feel more comfortable having a surgical mask for short periods of time for unavoidable outdoor exposure e.g. commuting from home to MRT station, and waiting for public transportation.
43. Why are masks recommended for outdoor workers at lower PSI than for the general public?
The threshold for usage of N95 masks or equivalent for protection of outdoor workers is suggested at lower PSI than for the general public as work commitments may require prolonged outdoor exposure or strenuous work on a regular basis. Employers should refer to the MOM guidelines for more details on situations where suitable masks or respirators have to be used. In general, work arrangements to reduce outdoor work such as frequent breaks and job rotation should be made to reduce prolonged or strenuous outdoor work. Use of mechanical aids such as trolleys, lifts or hoists instead of manual lifting and carrying could also reduce the strenuous nature of these activities.
Where outdoor work is unavoidable, employers should provide suitable masks (based on the MOM’s guidelines) to protect workers.
If N95 masks are used, employers and employees should note that these increase the effort of breathing. For some employees, this may cause discomfort in breathing, tiredness or headache. This may be due to their masks causing increased resistance to breathing, and a reduction in the volume of air breathed. Employers should consider instituting regular breaks and encourage hydration of employees using masks. Risk assessment, taking into account the usage of the respirators, individual employee’s heath conditions and nature of outdoor work must be conducted.
44. How will the haze impact patients in nursing homes and subsidised wards with natural ventilation?
These patients are indoors and sedentary. The healthcare institutions, such as hospitals and nursing homes, will monitor patients closely, and ensure ample circulation of clean air indoors.
45. For employees who need to take leave arising from the haze, but have run out of their leave entitlements, what can they do?
Employers are strongly encouraged to adopt a flexible and enlightened approach in granting time-off or leave. Some employees (especially those who are older, pregnant or have respiratory illnesses) may be unable to report for work due to health reasons. Other employees may need to take care of their family members, e.g. if their family member is sick or if there is a need for alternative childcare arrangements should schools or childcare facilities close as a result of the haze situation. In such situations, the following measures may be considered:
46. If employers decide that work should be stopped in view of the haze situation, can the employees’ salaries or annual leave be deducted on that day?
Employers who wish to suspend business operations should take note of the following:
47. Can employers ask employees to take annual leave if the company closes or operations have stopped due to the haze situation?
If the suspension is on a short-term and ad-hoc basis, employers should bear the costs of doing so and not deduct from the pay or leave entitlements of their affected employees. If the suspension of business operations is for longer periods, employers should discuss with their union and employees on the appropriate flexible work, leave and salary arrangements to be put in place.
48. Who can employees turn to if there are employer and employee disputes regarding leave and salaries?
Employers are strongly encouraged to put in place in advance internal company grievance handling procedures to manage any haze-related employment disputes. Employees should first approach their employers to resolve the matter amicably. If there are disagreements, the issue should be raised to the management via union representatives or your HR. If the dispute cannot be resolved amicably, you can make an online enquiry via this link (www.mom.gov.sg/feedback/) or call the MOM Contact Centre at 6438 5122, for further assistance.
