CPFM Smoke Management & Air Quality 3

Question 1

What is a 'smoke-sensitive receptor' in prescribed fire planning?

Accepted Answer

A population group or location that may be adversely affected by smoke exposure

Answer

An electronic sensor used to monitor airborne particulate levels

Answer

A fire manager who has documented respiratory health conditions

Answer

A weather station certified to measure air quality parameters

Question 2

Which burning condition best maximizes combustion efficiency and minimizes smoke production per ton of fuel consumed?

Accepted Answer

Low fuel moisture promoting complete flaming combustion

Answer

High fuel moisture content above 30%

Answer

Low flame temperatures that favor extended smoldering

Answer

Early morning ignition before atmospheric mixing begins

Question 3

What is 'spotting potential' in the context of prescribed fire smoke management?

Accepted Answer

The likelihood that firebrands carried by wind will ignite new spot fires outside the burn unit

Answer

The probability that smoke will drift into populated receptor areas downwind

Answer

The ability of observers to identify the smoke column from a distance

Answer

The capacity of forward-deployed monitors to detect PM2.5 spikes

Question 4

Which tool is specifically designed to predict smoke transport and PM2.5 concentrations from prescribed fires?

Accepted Answer

BlueSky — smoke forecasting framework integrating emissions and dispersion models

Answer

FARSITE — wildland fire behavior and perimeter growth modeling system

Answer

RAWS — Remote Automated Weather Station real-time data network

Answer

NFDRS — National Fire Danger Rating System for fire potential assessment

Question 5

What is the generally accepted minimum transport wind speed for adequate smoke dispersal during most prescribed burns?

Accepted Answer

7–10 mph

Answer

2–3 mph

Answer

15–20 mph

Answer

25–30 mph

Question 6

What should a prescribed fire manager do if real-time air quality monitoring shows PM2.5 exceeding health thresholds during an active burn?

Accepted Answer

Consider suppression actions, notify air quality authorities, and alert sensitive receptor locations

Answer

Continue burning and document the exceedance for the post-burn report

Answer

Increase fire intensity to push the smoke plume higher into the atmosphere

Answer

Request an EPA variance before taking any operational action

Question 7

What smoke management advantage does pile burning offer compared to broadcast burning?

Accepted Answer

Ability to ignite smaller fuel loads at optimal atmospheric windows, providing greater timing control

Answer

Higher combustion temperatures that generate more complete oxidation with zero visible smoke

Answer

Smoke concentrated in one spot, making it easier for wind to transport away

Answer

Elimination of PM2.5 production because pile fuels are pre-dried before ignition
