What is Method 10?
Method 10 is a procedure for measuring carbon monoxide (CO) in stationary source emissions using a continuous instrumental analyzer. Quality assurance and quality control requirements are included to assure that you, the tester, collect data of known quality.
What is the Method of carbon monoxide?
Most techniques used for the measurement of carbon monoxide in the environment employ spectroscopic methods or GC. Non-dispersive infrared (NDIR) spectroscopy and GC using flame ionization detection (FID) are the two most common methods used to analyze carbon monoxide in environmental samples.
How much CO is safe?
The OSHA personal exposure limit (PEL) for CO is 50 parts per million (ppm). OSHA standards prohibit worker exposure to more than 50 parts of CO gas per million parts of air averaged during an 8-hour time period.
At what level does a CO2 detector go off?
Low level: 50 PPM and less. Mid level: Between 51 PPM and 100 PPM….Carbon Monoxide Levels That Will Set Off Your Alarm.
Carbon Monoxide Level | Alarm Response Time |
---|---|
50 PPM | 8 hours |
70 PPM | 1 to 4 hours |
150 PPM | 10 to 50 minutes |
400 PPM | 4 to 15 minutes |
What is a safe CO2 reading?
What are safe CO2 levels indoors? The HSE recommends taking action to improve ventilation if you detect CO2 at concentrations of more than 1,500 parts per million. However, for an indoor space to be considered well ventilated, readings should be consistently below 800 ppm.
Do you put carbon monoxide detectors high or low?
Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing appliance.
When do I need to use method 10?
The use of Method 10 may be required by specific New Source Performance Standards, State Implementation Plans, and permits where CO concentrations in stationary source emissions must be measured, either to determine compliance with an applicable emission standard or to conduct performance testing of a continuous emission monitoring system (CEMS).
What is method 10 used to measure carbon monoxide?

How do you prepare to-10a?
Method TO-10A Pesticides/PCBs 14.2.2 A standard solution of the compound of interest is prepared in a volatile solvent (i.e., hexane, pentane, or benzene). A small, accurately measured volume (i.e., 1 mL) of the standard solution is placed into the modified midget impinger.
