Chris Gallagher of the Philadelphia Corporation for Aging says residents can, and should, call the heatline (215-765-9040) if they see anyone suffering from the excessive heat:

“They have the ability to send out a city health mobile team, that also has a nurse, out to the person’s location, take vital signs, look at the person’s environment to make sure they are going to be okay.”

Especially, he says, call if they are concerned about a senior citizen:

“If they need some tips on how to keep cool or they know someone who is experiencing heat stress.”
