| Categories | Health Effect | Cautionary Statement | Visibility * (miles) | PM2.5*** µg/m³ |
| Good | None | None | 10 + | 0 - 40 |
| Moderate | Possibility of aggravation of heart or respiratory disease. | People with heart or lung disease should pay attention to symptoms. | 6 - 9 | 41 - 80 |
| Unhealthy for Sensitive Groups | Increasing likelihood of respiratory symptoms and aggravation of lung disease such as asthma. | People with respiratory or heart disease, the elderly and children should limit prolonged exertion and stay indoors when possible. | 3 – 5 ½ | 81 - 175 |
| Unhealthy | Increased respiratory symptoms and aggravation of lung and heart diseases; possible respiratory effects to general population. | People with respiratory or heart disease, the elderly and children should avoid prolonged exertion and stay indoors when possible; everyone else should limit prolonged exertion.** | 1½ – 2½ | 176 - 300 |
| Very Unhealthy | Significant increase in respiratory symptoms and aggravation of existing lung and heart disease; increasing likelihood of respiratory effects of general population. |
People with respiratory or heart disease, the elderly and children should avoid any outdoor activity; actual medical conditions may warrant evacuation of severe cases; everyone else should avoid any outdoor exertion. ** | 1 – 1¼ | 301 - 500 |

Evacuation due to potential prolonged heavy smoke exposure should be considered for those physically distressed.** | < ¾ mile | > 500 |
* Determining Visibility
1. Face away from sun.
2. Determine the limit of your visible range by looking for targets at known distances (miles).
3. Visible range is that point at which even high contrast objects totally disappear.
4. Use the values above to determine the local forest fire smoke category.
Persons exhibiting respiratory or heart symptoms should seek medical attention. For pm 2.5 levels in several locations in the Wood Buffalo area visit the Wood Buffalo Environmental Association.
NOTE:
N95 (or R95, P95) masks can be beneficial for protection from smoke as long as they fit properly.
Evacuation: the most common call for evacuation is due to fire instead of smoke. Leaving the area may be a good protective measure for members of sensitive groups, but duration, intensity, and direction of smoke is difficult to predict. This is an unattractive option to many people.
Smoke is a known irritant to the lungs. There are strategies one can put in place that will minimize health symptoms in the event of a local wildfire:
* Square footage purifier covers?
* Does it have an ionizer? (Important for asthmatics to avoid or keep at a low setting).
* Where does the manufacturer suggest placement in the home for optimum benefit?
For further helpful tips, contact the Respiratory Health Education Department at the health center during normal business hours at (780) 791-6203 . For information on wood smoke, contact Environmental Health Services at (780) 791-6078 during normal business hours.
If you suffer from:
See your doctor annually, they may have medication suggestions or alterations to your current therapy to avoid possible exacerbations.
Environmental Health advises; "If you are having breathing problems - go to the Emergency Department at Northern Lights Regional Health Center or see your family doctor."
