I posted 2 restaurant grease fires today (on the other board) and both restaurants grease exhaust systems contained the fire and didn't spread and burn down the entire grease exhaust system.
The grease exhaust system is built with the sole purpose of containing the fire.
If the system has been designed, built, installed and inspected and it doesn't control the fire, then how come the lowly hood cleaner is at fault. Seems to me that the grease exhaust system, when built per NFPA 96 and UL 2221 & 1978 standards will control the fire.
The problem comes in that the systems haven't been built, installed or inspected to these standards and have sections that are uncleanable.
In reality, it doesn't matter how dirty the duct work is, if there is a fire, the exhaust fan will draw the fire up into the system and expel the fire and smoke through the fan out into the atmosphere.
I cleaned systems that haven't had the duct work cleaned since it was built back in the 60's.
The problem comes in that hood cleaners are being told that they are in the fire prevention business and they are buying into this.
Because they are buying into this thought pattern they are putting themselves at greater risk of liability if there is a fire.
Our paperwork, which the customer has to sign in order for us to service their system, states plainly that they forfeit their right of subrogation in case of any damage or fire unless it is due the specific action that we did that caused the damage.
Any hood and duct exhaust system that is cleaned, is automatically less likely to support the fire.
But the next day when they start cooking, the grease exhaust system is being coated with layer after layer of grease. I can't control the amount of build up, I can't force the restaurant owner to have it cleaned more often, I can't force the fire marshal to have it cleaned, yet I'm supposed to buy into the notion that it's my fault that the restaurant burnt down.
I don't buy into this logic.
This story has been put forth to get hood cleaners to think that they are more than they are so that a program/certification can be pushed forward and to increase the profitablity of the person propragating this notion.
If you can get the hood cleaner to admit that he is in the fire prevention business, then the attorney has you hands down because you didn't prevent the fire.
The only sure way to prevent the fire is to remove all cooking appliances from below the hood system and cook outside.
As long as there are grease exhuast systems, there will be grease in the system that will burn.
No matter how perfectly Matt cleans the exhaust system, it will burn if there is a fire.
So, we have a situation, that if there is a fire, the grease exhaust system will burn 100% of the time. That's what it's designed for. It's sole purpose and the reason so much time and money is spent on it, is to prevent the rest of the building from burning down.
It's illogical to conclude that the hood cleaner caused the restaurant to burn down, when he is the ONLY person that is truly doing something that might actually make a difference if there is a fire (and the fire suppressant guys too).
