Smoke Study · Airflow Visualisation

See the air.

Smoke studies that turn invisible airflow into evidence — for safety, compliance, and training.

What a smoke study really shows.

We generate controlled, traceable smoke to visualise how air moves through your environment. The result is a clear, real-time record of airflow patterns, dead zones, pressure differentials, ventilation gaps, and the impact of operator interventions — actionable evidence for QA, validation, engineering, and audit teams.

Studies are conducted at rest, during setup, in operation, and across routine interventions, with documentation retained as compliance-grade evidence aligned to PIC/S, TGA, and ISO 14644 expectations.

What we examine

Six conditions, captured on every study.

  • Unidirectional airflow

    First-air integrity over critical zones, with no ingress from lower-grade areas.

  • Recovery time

    How quickly laminar flow restores after personnel interventions or door openings.

  • Pressure cascades

    Differential pressure between adjacent grades — typically ≥10 Pa where required.

  • Turbulence & dead zones

    Eddy currents and vortex regions that trap, redirect, or stagnate particles.

  • Transfer pathways

    Airflow behaviour during material and personnel transfers between rooms.

  • At-rest vs in-operation

    Static and dynamic conditions, including operator activity per SOP.

Methodology

From plan to report — four deliberate steps.

  1. 01

    Plan

    Walk the site, define objectives, identify zones and acceptance criteria.

  2. 02

    Generate

    Deploy controlled, traceable smoke with calibrated equipment and safety controls.

  3. 03

    Capture

    Multi-angle high-resolution video and stills of airflow behaviour, at rest and in operation.

  4. 04

    Report

    Edited footage, annotated stills, written findings, and corrective recommendations.

What clients say

P Square has delivered more than ten airflow visualisation studies at our facility. Their on-site execution is professional and we've consistently appreciated the turnaround time on the edited footage. The custom HTML dashboard they ship with each study — searchable and organised by zone and date — saves us real time over folder-trawling, and the whole package has been genuinely helpful during audits.
