When Emergency Inspections Are Required
After a fire incident or system failure, emergency inspections are conducted. Inspectors evaluate damage and determine whether the system is safe to operate. Performance testing is often more detailed in these cases.
When Upgrades Trigger Inspections
Any modification to the exhaust system requires re-evaluation. Inspectors verify that upgrades do not compromise performance or safety. Updated documentation is also reviewed.
How Inspectors Check Airflow and Ventilation Efficiency
Airflow measurement is one of the most important aspects of exhaust system evaluation. Inspectors use specialized tools to measure air velocity and volume. These readings help determine whether the system effectively removes contaminants.
How Inspectors Evaluate Exhaust System Performance through airflow testing ensures balanced ventilation. Uneven airflow can cause smoke buildup and heat retention. Inspectors compare measurements against design specifications.
Inspectors also observe how quickly smoke is captured and exhausted. Delayed capture indicates performance issues. Correct airflow improves safety and comfort.
How Airflow Testing Is Performed
Inspectors use anemometers and airflow meters to take readings. Measurements are taken at hoods, ducts, and exhaust outlets. Results are documented for compliance records.
How Pressure Balance Is Evaluated
Negative and positive pressure levels are analyzed. Inspectors ensure that exhaust systems do not disrupt building pressure balance. Improper pressure can affect doors, appliances, and comfort.
How Capture Efficiency Is Observed
Smoke tests are sometimes used to visualize airflow. Inspectors observe how smoke moves toward the hood. Poor capture indicates design or maintenance issues.
How Inspectors Assess Grease and Contaminant Levels
Grease buildup directly affects exhaust system performance. Inspectors visually inspect ducts, hoods, and fans for grease accumulation. Excess grease indicates inadequate cleaning or poor airflow.
How Inspectors Evaluate Exhaust System Performance includes measuring grease thickness. Inspectors compare grease levels against allowable limits. Exceeding limits often results in mandatory cleaning.
Inspectors also check for dust, soot, and other contaminants. These materials can restrict airflow and damage components.
How Visual Inspections Are Conducted
Access panels are opened to inspect internal surfaces. Inspectors use flashlights and mirrors for hard-to-reach areas. Findings are recorded with photographs.
How Grease Thickness Is Measured
Thickness gauges or visual reference charts are used. Inspectors determine whether grease exceeds safe thresholds. This method provides objective evaluation results.
How Cleaning Frequency Is Evaluated
Cleaning schedules are reviewed against grease levels. Inspectors assess whether the current cleaning frequency is sufficient. Adjustments may be recommended.
What Mechanical Components Inspectors Evaluate
Mechanical components are critical to exhaust system performance. Inspectors examine fans, motors, belts, and bearings. Worn or damaged components reduce efficiency and increase failure risk.
How Inspectors Evaluate Exhaust System Performance includes checking alignment and vibration. Excessive vibration can indicate a mechanical imbalance. Early detection prevents costly breakdowns.
