Using an Aerosol Monitor

The actor’s exposure to glycols should not exceed 40 milligrams per cubic meter (mg/m3), and exposure to mineral oil should not exceed a 25 mg/m3 peak concentration. ENVIRON subsequently developed an “Equipment-Based Guideline” to allow production to use effects without having to conduct its stage-specific testing, provided the machines are used in accordance with manufacturer specifications, are well-maintained, and are functioning properly.

We STRONGLY encourage productions to conduct stage-specific testing of the venue’s air handling system and the machine used by the venue.

We recommend the following Aerosol Monitors:

• TSI DUSTTRAK II Desktop 8530 Dust/Aerosol Monitor
• TSI DUSTTRAK DRX Desktop 8533 Dust/Aerosol Monitor
• TSI AeroTrak 9306-V2 Particle Counter
• Fluke 985 Particle Counter

These aerosol monitors can measure both mass and size fraction at the same time and provide a gravimetric sample. They are suitable for indoor and outdoor applications.

Monitoring the concentration and dispersion of fog and other atmospheric elements helps maintain air quality and prevent potential health hazards. Utilizing the TrakPro™ Data Analysis Software alongside compatible TSI® equipment provides an effective solution for measuring and analyzing these environmental factors.

Understanding the Importance of Measuring Atmospheric Effects

Stage fog and atmospheric effects involve dispersing particles into the air, which can impact air quality and visibility. Excessive particle concentrations may lead to respiratory issues or reduced visibility, posing safety risks. Regular monitoring ensures that these effects remain within safe limits, promoting a healthy environment in performing arts venues.

Utilizing TrakPro™ for Measuring Stage Fog and Atmospheric Effects

The TrakPro™ Data Analysis Software, paired with TSI® instruments, facilitates the measurement of particulate matter and other atmospheric components. Here’s a step-by-step guide to using this device for ensuring safety during theatrical performances.

Step 1: Software Installation

Begin by setting up the TrakPro™ software:

1. Download: Visit the TSI website and navigate to the Service/Support page to download the TrakPro™ v5 software.
2. Install: Once downloaded, run the application file and follow the on-screen instructions to install the software on your computer.

Step 2: Initial Setup of the TSI® Instrument

Prepare your TSI® instrument for measurement:

1. Power Up: Connect the instrument to an AC power source or install the necessary batteries.
2. Turn On: Press the On/Off button to activate the device.
3. Warm-Up: Allow the instrument to complete its initial warm-up period to ensure accurate readings.

Step 3: Establishing Communications

Connect the instrument to your computer for data analysis:

1. USB Connection: Use a USB cable to connect the instrument to your computer. Ensure the USB-A end connects to the computer and the USB-B or USB mini-B end connects to the instrument.
2. Launch Software: Start the TrakPro™ software by double-clicking the desktop icon.
3. Verify Connection:

• For TrakPro™ v5 (AM520 and AM520i only):
  • Click on the “Devices” tab on the left side of the application window.
  • Confirm that the Instrument and Serial Number information is displayed.
• For TrakPro™ v4.7.x (all other TSI® products):
  • Navigate to Options | Software Configure… and select the appropriate instrument.
  • Go to Instrument Setup | Communications and verify that the Instrument and Serial Number are shown.

1. Troubleshooting: If the instrument details are not visible, refer to the TrakPro™ Data Analysis Software Installation Guide to troubleshoot driver installation.

Step 4: Conducting Measurements

With the device connected and software running, proceed to measure stage fog and atmospheric effects:

1. Calibration:

• Before taking measurements, calibrate the instrument according to the manufacturer’s guidelines to ensure accuracy.

1. Placement:

• Position the instrument in the area where fog and atmospheric effects are generated, ensuring it is not obstructed and can accurately sample the air.

1. Data Collection:

• Use the TrakPro™ software to start data collection. The instrument will measure parameters such as particulate matter concentration, which are critical for assessing air quality.

Step 5: Analyzing Data

Once data is collected, utilize the TrakPro™ software for analysis:

1. Review Data: Access the collected data within the TrakPro™ software interface.
2. Interpret Results:

• Analyze the concentration levels of particulate matter and other relevant parameters.
• Compare the results against safety standards and guidelines to ensure that atmospheric effects are within safe limits.

Step 6: Implementing Safety Measures

Based on the analysis:

1. Adjust Equipment:

• Modify the settings of fog machines or haze generators to maintain safe particle concentrations.

1. Ventilation:

• Ensure adequate ventilation in the performing space to dissipate excess particles and maintain air quality.

1. Regular Monitoring:

• Conduct routine measurements before and during performances to continuously ensure safety standards are met.

Ensuring the safety of performers and audiences during the use of stage fog and atmospheric effects is essential. By leveraging the capabilities of the TrakPro™ Data Analysis Software and TSI® instruments, theatrical consultants and safety inspectors can effectively monitor and maintain optimal air quality. Implementing regular measurements and adhering to safety guidelines not only enhances the performance experience but also upholds the health and safety standards critical to the performing arts industry.
