Toxic Endpoints

• For use in CA as the
• concentration of a state regulated substance
  in air above which there may be serious acute
  health effects following a single short-term
  exposure.

So where do TEELs fit in Response?

• California Air Response Planning Alliance
• Mission
• To provide actionable incident response
  information to protect public health and the
  environment from the impacts of accidental or
  deliberate releases of hazardous compounds into
  the air.

Goals

1. Promote and facilitate preparedness, training,
   and coordination of public health issues that
   arise during major air releases
2. Better understanding of using air quality data
   and health-based action levels to make rapid
   decisions about health and safety during
   emergencies

19
Consistency in Decision-Making

• AEGLs are the preferred health-based standards
  for use in major air quality and chemical
  emergencies
• Consider PALs depending on duration of exposure
• Other standards may be used depending on the
  circumstance
