==DISCUSSION==
SMOKE IS CAUSING OR EXPECTED TO CAUSE POOR AIR QUALITY AND REDUCED
VISIBILITY.
AIR QUALITY AND VISIBILITY DUE TO WILDFIRE SMOKE CAN FLUCTUATE OVER
SHORT DISTANCES AND CAN VARY CONSIDERABLY FROM HOUR TO HOUR.
AS SMOKE LEVELS INCREASE, HEALTH RISKS INCREASE. LIMIT TIME
OUTDOORS. CONSIDER REDUCING OR RESCHEDULING OUTDOOR SPORTS,
ACTIVITIES AND EVENTS.
YOU MAY EXPERIENCE MILD AND COMMON SYMPTOMS SUCH AS EYE, NOSE AND
THROAT IRRITATION, HEADACHES OR A MILD COUGH. MORE SERIOUS BUT LESS

YOU THINK YOU ARE HAVING A MEDICAL EMERGENCY, SEEK IMMEDIATE MEDICAL
ASSISTANCE.
PEOPLE MORE LIKELY TO BE IMPACTED BY OUTDOOR AIR POLLUTION,
INCLUDING PEOPLE AGED 65 AND OLDER, PREGNANT PEOPLE, INFANTS AND
YOUNG CHILDREN, PEOPLE WITH AN EXISTING ILLNESS OR CHRONIC HEALTH
CONDITION, AND PEOPLE WHO WORK OUTDOORS, SHOULD REDUCE OR RESCHEDULE
STRENUOUS ACTIVITIES OUTDOORS AND SEEK MEDICAL ATTENTION IF
EXPERIENCING SYMPTOMS.
WHEN INDOORS, KEEP WINDOWS AND DOORS CLOSED AS MUCH AS POSSIBLE.
WHEN THERE IS AN EXTREME HEAT EVENT OCCURRING WITH POOR AIR QUALITY,
PRIORITIZE KEEPING COOL.
PROTECT YOUR INDOOR AIR FROM WILDFIRE SMOKE. ACTIONS CAN INCLUDE
USING A CLEAN, GOOD QUALITY AIR FILTER IN YOUR VENTILATION SYSTEM

IF YOU MUST SPEND TIME OUTDOORS, A WELL-CONSTRUCTED, WELL-FITTING

N95 OR EQUIVALENT RESPIRATOR) CAN REDUCE YOUR EXPOSURE TO THE FINE
PARTICLES IN THE SMOKE. EVEN THOUGH EXPOSURE MAY BE REDUCED, THERE
CAN STILL BE RISKS TO HEALTH.
CHECK IN ON OTHERS WHO ARE IN YOUR CARE OR LIVE NEARBY WHO MAY BE
MORE LIKELY TO BE IMPACTED BY OUTDOOR AIR POLLUTION.
