Carbon Monoxide
Its the level at which we are not allowed to enter a building
What is 100 PPM?
It's the scale we use to measure resistance
What are Ohms?
It's the part in a furnace that confirms the venting system is in operational order.
What is a pressure switch?
it's the amount of brackets you would find on a new plastic riser.
What is 2?
this is the equivalent reading in LEL for 2.5% Gas in air
What is 50% LEL?
It's the one of the 2 main ways that CO is created, the other is flame impingement
What is lack of Combustion air?
When we are check for this, we are in fact checking for the flow of electrons
What is an amperage check?
It's a temperature actuate switch found in a furnace that opens on a rise in temperature
What is a high limit
You can use this to fill a cavity cut into an ICF foundation.
What is expanding foam?
This is what we would classify a leak that was 99%LEL indoors as close as possible to a fitting
What is an "A" Leak?
These are the 3 main factors that affect CO absorption in the body
What are time of exposure, concentration in air and rate of respiration?
This reading can also be expressed as a measurement of the potential difference
What is voltage?
In a natural draft furnace it's a temperature switch that closes on a rise in temperature
What is a combination fan/limit control
This is the minimum depth a horseshoe guard must be set into the ground
What is 600mm?
This is what we would classify a leak as if there were any readings in atmosphere
What is a "C" Leak?
It's the action you take when you read over 100PPM at the customer's front door
What is activate EMS?(911)
It's the type of circuit that only has one path for the electrons to flow.
What is a series circuit?
This component in a furnace steps down the input voltage of 120V to 24 volts
What is a transformer?
These are set upstream of a turbine meter to stabilize flow
What are straightening veins?
This is our gravest concern regarding a below grade leak if it cannot vent to atmosphere.
What is migration?
These are the characteristics of Carbon Monoxide
In a series circuit, if we increase the resistance we would expect to see this with the amperage
What is decrease?
This is the formula to clock an appliance for gas consumption
What is 3600/time X Dial size X 1000?
it's the depth of an open excavation in which you are required to get engineering approval.
What is 10 feet or 3.1 meters?
This is the level of gas in a home at which we need to evacuate the homeowners and ourselves
What is 10%LEL
