Definition
Factory calibration refers to the process of adjusting and fine-tuning the parameters of a device or instrument during its manufacturing process to ensure that it meets specified performance standards and accuracy requirements. This calibration process is typically carried out in the factory or production facility where the device is being manufactured. The goal of factory calibration is to make sure that each device coming off the production line performs as closely as possible to a predefined reference or standard.
A method for measuring the concentration of an air pollutant in the ambient air that has been designated as an equivalent method in accordance with 40 CFR Part 53. A FEM does not include a method for which an equivalent method designation has been canceled in accordance with 40 CFR Parts 53.11 or 53.16.
Fenceline monitoring is a practice used to measure and assess air quality and emissions around the perimeter of an industrial facility, typically one that handles hazardous or potentially harmful materials. The purpose of fenceline monitoring is to identify and quantify any emissions or pollutants that may be released into the surrounding environment, especially those that could pose health risks to nearby communities or the workforce.
Filtration is a method to subset data by time or location. This type of filtering allows you to see differences in aggregations that might result from factors such as weather or emission events (e.g., high traffic times, wildfires). You might also consider filtering by time (e.g., hour, day, weekday/weekend, season). For example, comparing averages of nitrogen dioxide (NO2) concentrations by the hour of the day and by weekday and weekend may show the effect of traffic activity on local pollution conditions.
A type of computer software or set of instructions programmed on a hardware device (e.g., an air sensor).
A method of sampling and analyzing the ambient air for an air pollutant that is specified as a reference method in 40 CFR Part 50, or a method that has been designated as a reference method in accordance with 40 CFR Part 53. An FRM does not include a method for which the U.S. EPA has canceled a reference method designation in accordance with 40 CFR Parts 53.11 or 53.16.
“””FIDOL factors”” in the context of odor assessment and management are used to describe the various attributes and characteristics of odors. The acronym “”FIDOL”” typically stands for the following factors:
1. Frequency: Refers to how often the odor occurs, whether it is continuous, intermittent, or occasional.
2. Intensity: Indicates the strength or concentration of the odor, whether it is weak, moderate, strong, or pungent.
3. Duration: Describes how long the odor persists, whether it is brief, lasting, or prolonged.
4. Offensiveness: Relates to the level of offensiveness or unpleasantness of the odor, which can vary from barely noticeable to highly objectionable.
5. Location: Specifies where the odor is originating from and where it is perceived, as well as whether it is localized or dispersed.
These factors are used to assess and characterize odors, helping in odor impact assessments, mitigation strategies, and regulatory compliance in situations where odors are a concern, such as in industrial, environmental, or community settings. Understanding FIDOL factors is valuable for managing and addressing odor-related issues effectively.”
