Select test method(s) to meet test data objectives
Determine adequate gas sample volumes
Evaluate possible errors and biases, correct approach if necessary
Determine time required for test with margin for delays
Estimate the cost of the test and economize when possible or necessary
Prepare Sampling Location(s)
Inform plant operators of test objectives and requirements for successful completion
Determine accessibility to duct.
Does the location have sampling ports installed? If
not, please see our figure of placement of sampling ports for a Round
duct or for a Rectangular duct.
If the type of sampling you need involves manual (eg. Isokinetic) AND
continuous emissions monitoring, you will need to install
an additional CEM sampling port (see the figure).
Remove obstructions of beams or guardrails
Install monorail brackets above each manual sampling port. Please see our drawing
of a monorail bracket for details of what it would look like.
Check if sampling ports can be opened
Check for in-stack obstructions, such as an opacity monitor
Check for sufficient space for personnel AND equipment.
Check for lighting
Verify scaffolding meets OSHA requirements
Is a man-lift available? (when proper or reasonable
access is unachievable by any other means)
Locate Electrical Power (preferably within 50 feet of the sampling location)
One 20A 115V circuit for each sampling train operating at the same time.
One 30A 480V circuit for each sampling trailer. (Note this
is a DEECO specific requirement, other companies will have
different requirements)
Evaluate safety requirements
What type of PPE (personal protective equipment) will be necessary?
Fall protection?
Protective clothing? (eg. long sleeve shirt, splash protection, safety glasses, hard hat)
