When smog levels reach critical levels, steps should be taken immediately to protect the most vulnerable members of society and reduce emissions that could worsen local air quality. A smog alert response plan is a written protocol of actions to be taken by an organization, government agency, company or municipality when poor air quality is forecast. Such a plan should include a mechanism for informing residents or employees of the potential health threat, as well as specific actions that can be taken to reduce the risk.
More information on developing a smog alert response plan and additional suggestions for what you can do to combat smog is available in the ministry publication – Smog Alert Response: A Municipal Guide to Action.
