I feel at home already, I see some of my compatriots beat me over here.
The goal of good exhaust cleaners is to make the resturant fire safe. If we do a PJ job, buildings burn down and people get hurt and can die. A number of us have goal of cleaning to bare nekkid metal. We also look down on those that do not clean to bare nekked metal.
We do have similar equipment to the roof cleaners, and we do face the same safety challanges as roof cleaners.
I started my business in 1978, servicing fire suppresion equipement, including cleaning hoods. I have also been a firefighter, volunteer, paid on call, full time and wore a white hat for a couple of years. With my experience and my advanced age I have an attitude towards PJ work. I had a friend killed in a fire several years ago. the contractor and builing inspector on that job did not do their jobs. They got a weekend in jail, Randy got a hole in the ground.
That adds to my attitude. My professional goal is to never put anyone in a hole in the ground because of something I or one of my employees does.
I am a member of the Grease Police, and damn proud of it. I wish more of the fire orgs had the attitude of the Grease Police.
