Across Areas of Los Angeles County
Smoke from the fire burning in Griffith Park is forecast to create
unhealthful air quality conditions today for central Los Angeles County,
east San Fernando Valley and west San Gabriel Valley.
All individuals are urged to exercise caution and avoid unnecessary
outdoor activities in the smoke-impacted areas.
Wildfires generate smoke containing fine particulates known as PM10 and
PM2.5. Concentrations of fine particulates may reach unhealthy levels today
in the smoke impacted areas.
In areas with unhealthy air quality, everyone should discontinue
prolonged, vigorous outdoor exercise lasting longer than one hour. Examples
of the kinds of outdoor activities that should be avoided are calisthenics,
basketball, running, soccer, football, tennis, swimming laps, and water
polo. Susceptible persons, such as those with heart or lung disease, should
avoid outdoor activity entirely.
For more tips on avoiding health impacts from the smoke, see

AQMD is the air pollution control agency for Orange County and major
portions of Los Angeles, San Bernardino and Riverside counties.
