Exhaust Airflow Calculation is a practical industrial safety calculator that allows for the rapid and accurate calculation of the required exhaust airflow (Q) for local exhaust hoods on-site.

According to the Rules on Occupational Safety and Health Standards, the installation of local exhaust systems with appropriate performance is required in processes handling hazardous substances subject to management or specially managed substances. This app supports the design review and performance verification of local exhaust systems by instantly calculating the required exhaust airflow upon inputting the hood type, specifications, and control airflow velocity.

■ Key Features

- Calculation of exhaust airflow by hood type

- Enclosing/Booth-type hoods: Q = 60 × A × V

- External hoods: Application of calculation formulas based on installation location and presence/absence of flange

- Support for inputting hood specifications such as circular and square openings

- Reflection of control airflow standards

- Reference to control airflow standards by hood type from Occupational Safety and Health (OSHA) notifications

- Calculation by directly inputting measured control airflow values

- Field use

- Displays calculation basis (applied formula) for use in report writing

■ Useful for the following users

- Workplace safety managers and health managers

- Practitioners involved in the design, construction, and inspection of local exhaust ventilation systems

- Personnel responsible for preparing documents related to the Korea Occupational Safety and Health Agency (KOSHA) (work environment measurements, local exhaust ventilation system inspections, etc.)

- Students and exam candidates studying the field of industrial ventilation
