Four first responder agencies in northwest Harris County received pet oxygen mask kits on Tuesday. Invisible Fence of Greater Houston donated 50 oxygen mask kits to the Spring Fire Department, Cypress Creek EMS, Tomball Fire Department and Northwest Community Health during a ceremony at Spring Fire Station 71. Spring Deputy Fire Chief Joel Crenshaw said the Spring Fire Department has been using donated masks and has saved several pets suffering from smoke inhalation. "This donation today will allow to have these kits with three different sized masks on all of or fire engines," he said. "This is a serious upgrade to help us save pets, as well as people." The oxygen and masks and kits were awarded through Invisible Fence's Project Breathe, a program that was launched 13 years ago. Nine pet oxygen masks were awarded to the Spring Fire Department's nine stations, and Cypress Creek EMS received 30 pet oxygen mask kits to outfit each of the paramedic vehicles.
