Sampling IAQ Contaminants Courses
Air Sampling for Mold I
Goal: Enable students to collect viable and spore trap air samples for mold, and to understand the advantages and disadvantages of each method.
Lesson 1: Spore Trap Sampling
Objective – Describe the needed equipment and step-by-step procedures for collecting spore trap samples.
Lesson 2: Viable Air Sampling
Objective – Describe the needed equipment and step-by-step procedures for collecting viable air samples.
Air Sampling for Mold II
Goal: Understand how to develop a sampling plan and interpretation strategy for which students understand the limitations.
Lesson 1: Limitations
Objective – Describe the limitations of air sampling due to variability, error, unknown association with mold growth, and difficulty in interpretation.
Lesson 2: Sampling Plan
Objective – Establish a sampling plan that answers the following critical questions:
- Why am I sampling?
- How many samples should I take?
- Where should samples be collected?
Lesson 3: Interpretation
Objective – Apply simple interpretation strategies for laboratory results from spore trap and viable air samples.
Surface Sampling for Mold
Goal: Understand how to utilize surface sampling to confirm mold growth, identify mold type, or quantify surface cleanliness.
Lesson 1: Tape Lift
Objective – Explain the advantages and disadvantages of tape-lift samples and describe situations where this method is best suited.
Lesson 2: Swab
Objective – Explain the advantages and disadvantages of swab samples and describe situations where this method is best suited.
Lesson 3: On-site Analysis
Objective – Explain the difference between the following technologies for on-site analysis of surface samples: bioluminescence, immunoassays, and fluorescence.
Other Sampling for Mold
Goal: Enable students to collect bulk and dust samples for mold. It is also our goal for students to understand the situations that are best suited for the collection of bulk, dust, mVOC, and mycotoxin samples.
Lesson 1: Bulk Sampling
Objective – Collect bulk samples and understand the situations for which they are best suited.
Lesson 2: Dust Sampling
Objective – Collect dust samples and understand the different types of laboratory analysis available. Also, be able to collect ERMI samples and know how to interpret the results based on a national study.
Lesson 3: MVOC and Mycotoxin
Objective – Identify the scenarios where mVOCs and mycotoxins should be sampled, and describe the laboratory analysis.
Sampling for Bacteria
Goal: Know when, where, why, and how to sample for bacteria.
Lesson 1: Air
Objective – Describe the situations that may require air samples for bacteria, outline the steps for collecting an air sample, and describe the limitations of interpreting results.
Lesson 2: Water
Objective – Collect water samples for bacteria with a special focus on Legionella sampling.
Lesson 3: Swab Samples
Objective – Collect swab samples for bacteria with a special focus on sewage damage.
Sampling for Allergens
Goal: Enable students to collect samples for common allergens and determine if the results are elevated based on guidelines.
Lesson 1: Air Sampling
Objective – Identify the equipment and procedures needed to collect samples for airborne allergens.
Lesson 2: Dust Samples
Objective – Describe the needed equipment, sampling locations, and step-by-step procedures for collecting a dust sample.
Lesson 3: Analysis and Interpretation
Objective – Describe the different analyses available for allergen sampling along with guidelines for interpreting the results.
Measuring Particulate Matter
Goal: Understand how to measure particles with direct-read instruments and laboratory-based methods when particle identification is needed.
Lesson 1: Direct-Read
Objective – Distinguish between photometers, optical particle counters, and condensation particle counters and select the right device for different scenarios.
Lesson 2: Laboratory-Based
Objective – Describe collection methods and laboratory analysis that results in the identification of particle types and sources.
Goal: Understand how to establish a sampling plan for volatile organic compounds (VOCs), which may involve the use of direct-read instruments and/or laboratory-based methods.
Lesson 1: Direct-Read
Objective – Determine when photoionization detectors (PIDs), flame ionization detectors (FIDs), and/or direct-read tubes should be used to measure VOCs.
Lesson 2: Laboratory-Read
Objective – Determine when active sorption, passive diffusion, and/or whole air canisters should be used to collect VOC samples for laboratory analysis. You’ll also be able to describe analysis by gas chromatography and mass spectrometry.
Lesson 3: Sampling Plan and Interpretation
Objective – Establish a sampling plan for VOCs and interpret the results.
Measuring Carbon Monoxide
Goal: Understand how to assess and measure carbon monoxide under normal and worst case conditions as part of an initial IAQ assessment.
Lesson 1: Assessments
Objective – Visually assess an indoor environment to identify warning signs of possible carbon monoxide problems.
Lesson 2: Measurements
Objective – Measure carbon monoxide under normal and worst case conditions.
