What is a PLM file

PLM files mostly belong to ALOHA. PLM files are Plume Model Output Files used for hazard simulation and environmental safety analysis.
They store data generated by plume dispersion models that calculate how chemicals spread in the air during accidental releases. This information is used for risk assessment and to determine safe zones during emergency response.
Key points summarized by FilExt.com include:

Simulation Data: Holds numerical values and results from plume dispersion calculations.

Hazard Evaluation: Provides critical details to assess how far and fast a chemical plume may travel.

Software Compatibility: Primarily used with the ALOHA plume model, though many PLM files are plain text and can be viewed with a text editor.

FilExt.com tip: For more detailed information, visit the ALOHA Software webpage.

How to open PLM files

You need a suitable software like ALOHA to open a PLM file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your PLM file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a PLM file directly in the browser:.
