GENERAL INFORMATION

Air
Pollution
San Diego's
main air pollution problem is ozone (smog), formed from chemical
reactions of hydrocarbons and oxides in the presence of sunlight.
According to County of San Diego Air Pollution Control District 1993
Annual Report, short-term exposure (one to two hours) to smog adds
stress to the body and can cause constriction of the airways, forcing
the respiratory system to work harder to provide oxygen. Long term or
chronic exposure to smog can cause damage to the deep lung tissue even
after obvious symptoms of coughing or sore throats disappear. Ozone
damages the individual air sacs (alveoli) in the lungs where oxygen and
carbon dioxide are exchanged. Over time, these tissues can become
permanently damaged, reducing the "ability to function and essentially
accelerating the natural loss of lung capacity". Ozone is particularly
harmful to senior citizens, children, and individuals who suffer heart
or lung disease. Nearly 1.3 million county
residents are considered to be at a high health risk from polluted air.
-
Definitions
The
following stages of air pollution episodes are used by the APCD which
monitors and declares the episodes for forecasts.
-
Air
quality is considered "good" when the Pollution Standard Index (PSI)
is between 0 and 50.
-
Air
quality is moderate when the PSI is between 51 and 100. Sensitive
persons should reduce strenuous outdoor activities.
-
Air
quality is unhealthful when the PSI is between 101 and 199. A Health
Advisory is declared when the air quality PSI is 138 or more. When a
Health Advisory is issued, athletes should avoid strenuous outdoor
activities. (California established the health advisory in 1991 after
medical research showed that ozone poses a health threat at lower
concentrations than those specified by federal standards.)
-
Stage I Alert (Very Unhealthful): the air quality PSI is 200 or
more. During a Stage I episode, the general public should avoid
strenuous outdoor activities.
-
Stage II Alert (Hazardous): the air quality PSI is 275 or more.
During a Stage II episode, everyone should remain indoors.
Procedure to follow:
Air Pollution Awareness and Abatement:
Top
STEP 1
Risk
Management
Maintain Air Pollution Awareness Program
Train
staff and faculty in Air Pollution mitigation procedures.
STEP
2
Students, Faculty & Staff
Reduce Pollutants
Cars
pollute most during start-up. According to the APCD, hydrocarbon
emissions generated during start-up are six times more polluting as the
emissions produced during a ten mile commute. Reduce driving: combine
errands, carpool, use public transportation, ride a bicycle or walk.
Commuter Computer will assist by matching interested carpoolers (237-POOL).
Keep
vehicles in good running condition. Keep tires properly inflated. Use
reformulated gasoline or drive a clean-fuel vehicle.
Don't
top off the gas tank. Gasoline spills evaporate and contribute to smog.
Support
the smog check program. Removing emission control equipment does not
improve engine performance.
Report
"smoking" vehicles. Call 1-800-28-SMOKE to report
vehicles with excessive tailpipe emissions, or 694-3340
to register any other related complaint.
Don't
use aerosol spray products. Most aerosols contribute to smog.
Use
water-based paints and solvents. Oil-based paints and solvents contain
three to vie times more toxic solvents than water-based latex paints. Use
brushes or rollers instead of sprayers.
When
starting a barbecue don't use traditional charcoal lighter. Alternatives
include electric lighters, cardboard chimneys, or low Volatile Organic
Compound (VOC) fire lighter fluids.
Use
energy efficient lighting; turn off appliances when not in use. Raise the
air conditioner temperature level and lower the heater temperature
setting.
If
an air pollution episode is declared:
STEP 1
Risk
Management
Announce Air Pollution Episodes
Using
the Air Pollution Episode Notice form and the District E-mail system,
advise District employees of Smog Alerts and Health Advisories as they are
set and removed. Ensure, at minimum, that the following individuals
receive appropriate notice:
- Chancellor & Presidents
- Athletic Directors
- Evening Division and Night Administrator
- Health Services
- Student Services
- Operations
- Maintenance
- Warehouse
- Public Information
- Public Safety
- Switchboard
Ensure
that the Notice form details recommended activity for the specific
episode.
Continuously monitor and evaluate air pollution conditions until the
episode is terminated.

STEP
2
Physical Education Instructors, Event
Coordinators
Reduce Class Activity Levels
Ensure
student activity levels reflect recommendations established for each smog
alert stage. If necessary, cancel and/or reschedule events around
forecasted and ongoing air pollution episodes.
STEP
3
Faculty, Staff, and Students
Reduce Physical Activity
Do not
increase personal respiratory rate more than necessary. persons with
respiratory or cardiac difficulties, the young and the elderly, are at
greater risk.
Do not
smoke. Limit or curtail activities that will add other pollutants (spray
paint, solvents) to the air being breathed.
Remain
indoors (exposure can be reduced by as much as fifty percent).
Student
participation in outdoor physical activity is not required during
episodes; however, students should report to all classes.
STEP 4
Operations and Maintenance
Reduce Pollutants
Discontinue burning, spray painting, roofing, asphalt paving and surface
coating activities as required by the specific episode requirements.
STEP
5
Risk
Management Submit
APCD Survey
Submit
survey as required by the San Diego Air Pollution Control District.
