I was at this very upscale restaurant in West Los Angeles yesteday.
The kind of place that the rich and famous would eat at.
The kind of place where they look and talk down to you while you are there.
Their exhaust company is still blowing powder! :confused:

Is the year 1983 or is it 2003 - I am confused?

Actually their is at least one other company located in Lemon Grove, CA that has about 3500 restaurants that they service and I was talking with him and they do it the ol' fashioned way.

Scrape and powder everything.

NFPA 96
11.4.8 After the exhaust system is cleaned to bare metal, it shall not be coated with powder or other substance.
 
There are at least two companies in Colorado still blowing powder.

To top it off, we just were invited to bid on a school district in Colorado. In the requirements for the job it was stated that we were to blow powder after cleaning the system. We called the district and asked if they were aware that they were asking us to go against code by doing this. Their reply was to the negative.
They took this out of the requirements for cleaning.

We asked if they wanted all of this out of their systems during the initial cleaning and explained how hard it was to relieve the system of this contaminant as this was done in the past to all of their older schools. Long story short, they are now revising the bid and we will be revisiting with them after the first of the year.
 
I agree with you David. This guy's explanation is that he doesn't feel it is safe to remove the fuel load, and then in 60 to 90 days you'll have 1/2 a fuel load there and it will burn just as easy.

I think that he doesn't fully understand how a grease exhaust system in theory is supposed to work.

Contain the fire until the fuel burns off without setting the roof on fire or catching combustibles that are too close on fire.

I'm not telling you this (David or other experienced hood cleaners) because you don't know it, but for the benefit of others new to the field.

That's why such a thick gauge metal is used, an upblast fan, no wiring inside of the ductwork, fan motor out of the stream of the exhaust (potential fire), and careful distances to combustibles.

It's basically a fancy metal chimney designed ultimately to have a fire inside of it but not burn down the building.

That's why it's so important when inspecting an exhaust system to know what you are seeing so that you can tell compliant with non-compliant. And I'm not talking about just whether it's the law in your area or even if it's enforced, but that it's just simply not safe to have it any other way.

This guy knew that the NFPA didn't allow it, but he knows also that their isn't local enforcement to stop him.

It will just take time and education before someone sees that using the powder althougth somewhat effective isn't going to stop a fire if one occurs. Removing the grease and making sure that a proper operating fire suppressant system functions when it's supposed to is more important than powder.

There used to be a person out of Walla Walla who scraped what he could reach, and then blew powder. He claimed it was a saponification agent or a fire retardent. He also pointed to the white covering and said with pride " Look how clean it is!" He then left a certificate that referenced NFPA 96, SubSectoin C. The certificate expired in 60 or 90 days. Now I have only had access to NFPA Codes since 1988, while working as a full time firefighter. I have never seen that part of NFPA 96. He was also unlisenced. unisured and probably not even certified! Ever try to clean a hood after that stuff has been thrown into the system? It slows down the air flow, allows more grease build-up, plugs up the fan, and forms a film on the fire suppression nozzles that can keep the nozzle caps on the nozzles. I have seen the stuff so thick, it actually falls off the duct onto the grille.

He is out of business now, but has a family member, named Carl, still in the trade. No more powder blowing. But he does follow the family tradition, no lisence, no insurance, no bond, no worker's comp and deals in cash. I watched him clean a place one night. He pulls up in an old Econoline, pulling a trailer. he saw my van and looks at me. He then hollers that he know all about guys like me, charging $100.00 to service the Ansul system in 30 minutes, charging too much money. He wants to make that much but the Ansul company won't return his phone calls. I ask what he is doing and he tells me he is going to clean the exhaust system. I ask if he has to be insureed or lisenced. He says he has all the insurance and lisences he needs. I ask if I can see the proof of insuranance and lisences. He gets pissed and starts to swear at me, asking if I am the fire marshall. He uses a descritive term before "fire marshall" He gets a cup of coffee, sets up the ladder. He goes to the roof, coffe cup in hand. and takes the fan apart. His helper goes in side and lays canvas on the grille and fryers. Carl Then throws his garden hose on the ground and starts to find the ends. No hose reel. After he gets the hose strung out, he starts the PW. No gas. He gets out the gas can. No gas. He goes next door to the gas station, fills the gas can and fills the PW. He starts the PW w/a rope, no battery ignition or starter. he uncoils the pw hose, no reel. The hose goes to the roof and he Pressure washes the fan. No hot water, no chemicals. He is done and throws the hose on the trailer, not coiled up, just in a pile. Unhooks the garden hose, same pile as the pw hose. He then goes back on the roof. I notice he doesn't use a flashlight, his eyes are bright enough. I am done with my burger. I go inot the resturant to dispose of the wrapper. I ask his helper what he is doing, that I have seen other people use a pressure washer to clean hoods. I ask how they are going to control the waste water. The helper says they only scrape the grease because there is no way to control the water, it just gets all over everything. He tells me the guys that use water are just scammin' people because everybody knows water won't cut grease. I ask how much do you charge? He replies $120.00. Now this is a job I bid at $175.00 to clean, and was turned down becasue I was too much. But I do service the fire suppression system. I also know that they don't get the grease out. I ask how long to do this job, asking where the next job is. and was told about 3 hours, and there is no next job, not enough time. I said 6 hours, because there are 2 of them x 3 = 6 hours. That is $20.00 an hour. the helper look confused. I ask what do you make? He says $6.50 and hour, cash. I jus t shake my head, go to my next job and make somewhat more than $20.00 an hour. I also use hot water, chemicals and leave the job clean to bare metal. The guy is still in business.

I picked -up one of his customer 4 months ago. My sales pitch included cleaning the grease off the roof, which we did. When I showed up, I was asked how long ? I said about 3-4 hours. I was told Carl took from 10:00 PM to 5;00 AM, with a helper. We took from 10:00 AM to 2:00 AM. The next day I went back and asked how we did. they noticed we had polishe the hood, cleaned hte filters and mopped hte floor. we did the place last week, and trimmed an hour and halfo off hte time. Next time, we can knock another 1/2 hour off.

What on earth does this mean??????????? The fuel load is the build up??
 
Aren't people like us actually hired to reomove the "fuel load"?
 
Yea, matt. I can see you operate one of those scam Operations yourself. Looking at the photo, I can see 3 spots of grease you left behind. If you were using powder, those spots would be as clean as the photos at the start of this thread. Not only would those spots be clean, you would not take as long to do your job. the powder is so easy to apply, just turn on the fan, point your portable fire extinguisher filled w/powder and squeeze the lever. Maybe you could even do the job while the resturant was in operation! That would be great for those 24 hour operations. This is such a simple solution I am going to go into the shop today and recharge those extra fire extinguishers. In fact, I will offer a special to those on the boards. "Doug's fire retardant/saponifiaction application devices. Perfect for 2 man opertions. Tech applys chemical while lead man collects for service. In and out in 10 minutes or less. Application tools for $200.00 each. Average sale to customer is $500.00. Application as per NFPA 96 Subsection C. Method approved by NFPA (National Fling Powder Associaton)"' This will revolutionize the business , and we can get rid of those noisy pressure washer washing machines. Color co-ordinated powder available at extra cost.

Bryan, I see that you have not sent me your money for your colored powder certification test. You know the rules, no money, no certification. Also, you can blow powder, but you cannot blow chunks.
