SEATTLE, Wash. -- Some Mariners fans are getting to see their team play at Safeco Field for the first time Tuesday night.

That's because a section has been carved out as a peanut-controlled zone.

A bag of peanuts may be must-have for many fans going to see the Seattle Mariners.

But that's what's kept many families from ever setting foot at Safeco Field - because of severe peanut allergies.

But before Safeco opened up Tuesday night, KIRO 7 Eyewitness news got a special look at what's being done to let fans take their kids out to the ball game.

Before, Michael San Soucie has only been able to bring a picture of his 4-year old son, Nathan, to Safeco Field.

Now, Nathan himself will make an appearance.

Michael San Soucie commends Safeco Field, “they've done a great job cleaning and we feel safer coming.”

San Soucie and his son will be sitting in a 170-seat, peanut-controlled area down the right field line.

It was cleaned three times before Tuesday’s game, and volunteers picked the area over again to get the peanuts out.

And adjacent concession stands have taken peanuts off their menus.

Rebecca Hale from the Seattle Mariners says, “we know we can't guarantee that every single peanut particle will be out of the area. It's certainly going to be a much reduced risk.”

Peanut allergies affect approximately 12 million Americans.

Richard Hawes says, “people who don't think peanut allergy is a real allergy, all they gotta do is take someone like my grandson to the hospital when he's blue and can't breathe.”

Hawes will be sitting near the San Soucies, with his grandson, Ian.

He’s been wanting to bring Ian to a Mariners game since he was born. But Ian was diagnosed with the allergy at 11 months.

Hawes sees a value in sitting in the area, “grandsons and grandfathers need to yell together, cry together, have a good time.”

Now, he’ll be able to sit right next to his grandson after a lot of waiting – Ian is now 20 years old.

Hawes tears up, “I now have the opportunity to take my grandson to the ball game.”

There is a row of empty seats that also serves as a buffer zone for the peanut-controlled area.

For any families still a little nervous, there will also be wipes available.

The zone was sold out Tuesday, but there are still a handful of peanut-free tickets available for the game on September 9th against Texas.
