ORONOCO, MN -- He grieved the death of his 3 year-old granddaughter by going to lawmakers.



Now, David Griggs efforts have paid off with a slew of new rules aimed at protecting people from carbon monoxide poisoning.



NewsCenter's Jenna Gordon talked with the parents of Hannah Griggs about what this now means, and the special honor being bestowed on the man who helped start it all.



In March of 2004, the Griggs' family changed forever.



"Jason woke up from a loud crash and found me unconscious at the foot of the bed, and he though I hit my head so he called 911. And when they got here, they found themselves in a very different situation," says Melissa Griggs



Jason and Melissa suffered from carbon monoxide poisoning.



Emergency responders quickly went to check on the couple's two young girls.



"When they walked into Hannah's room they knew some thing was very, very wrong.



They found the Griggs' 3 year-old daughter dead.



"They're estimate was 800 PPI. A normal CO detector should sound at 30 PPI, so it was extremely high."



Investigators say the furnace malfunctioned.



Jason Griggs says, "We had about six smoke detectors but no carbon monoxide detectors at the time."



To help grieve Jason's father, David, took matters to lawmakers trying to get carbon monoxide detectors mandated in all homes.



"It was refreshing to see the politics work like that. Most were behind it. It moved a lot faster than I think a lot of people expected it would actually pass," says Jason.



It took three dedicated years to get detectors mandated, and to help recognize his efforts David Griggs is receiving a reward from the Minnesota Fire Chiefs Association.



Something his family is very proud of.



"He was just so compassionate of not having any other family ever have to go through what we went through."



The Griggs say the law is helping them find closure, and while it will never bring Hannah back, it is a start for them to heal.



The new state-wide rules began in January with all newly constructed homes and apartment units having a carbon monoxide detector.



By next August, all single family homes must be equipped with an alarm.



And by August of 2009, all other apartments and multi-family units will need to have the device.
