GasTiger 2000 Portable Multi-Gas Detector — Arsine (AsH₃) Monitoring and On-Site Operator Training for a Semiconductor Component Disassembly Facility (Pyeongtaek)

This case study covers the delivery of a GasTiger 2000 portable multi-gas detector to a semiconductor component manufacturer in Pyeongtaek, along with on-site operator training.

The GasTiger 2000 supplied for this project can be configured with cost-effective, customizable gas sensors at the time of purchase. The customer requested this unit specifically to monitor arsine (AsH₃) gas, which can be released during the disassembly of semiconductor components, and also requested training on how to use the device.

What is Arsenic (As)?

Arsenic is a highly toxic substance classified as a Group 1 carcinogen, sometimes referred to as the "king of poisons." It is also used as a compound in pesticides, rodenticides, and agricultural chemicals.

Arsenic is widely used in the semiconductor industry, and arsenic-lead compounds are also used in automotive batteries, among other applications. Because semiconductor industry workers are often directly or indirectly present in environments where arsenic compounds are used, the risk of arsenic poisoning increases significantly without proper equipment and safety measures. Continued exposure while already affected raises the likelihood of a serious incident.

The Safest Way to Prevent Arsenic Poisoning Incidents

The GasTiger 2000 portable multi-gas detector.

The GasTiger 2000 accurately measures a range of hazardous gases — including sulfur oxides, nitrogen oxides, arsine, and hydrogen fluoride, as well as odor-causing gases such as ammonia (NH₃) — in ppm units. It supports up to 6 sensor slots, selectable from over 40 gas types, allowing up to 7 gases to be monitored simultaneously depending on configuration.

Rather than a complex interface, the device uses a simple color-icon display, making it easy for first-time users to operate confidently on site.

Arsine Detector Inspection

With a multi-gas detector like the GasTiger 2000, a malfunction can create a genuine safety risk on site. For this reason, every unit is tested and inspected in-house prior to shipment to check for defects or errors, ensuring user safety.

When first powered on, the multi-gas detector requires roughly one minute for sensor warm-up before it can measure gas accurately. We recommend powering the unit on ahead of time so the sensors are warmed up before use on site.

After powering on the unit, we checked the reading immediately. Since the office where this check was performed has no AsH₃ present, the reading correctly measured 0 ppm.

This is the semiconductor factory where the unit was delivered. We provide free product training upon request, so alongside this delivery, we conducted hands-on training directly for the staff who would be using the device. As noted above, arsenic is a Group 1 carcinogen, so it was important for semiconductor workers to fully understand how to use the gas detector correctly to help prevent arsenic poisoning.

We demonstrated the GasTiger 2000 to the on-site workers and walked them through its operation. Since the device is not complicated to use, the training focused mainly on practical operation and the functions available on site. We also explained the fall-detection alarm feature in detail — if a user were to collapse due to arsenic exposure, the resulting impact triggers a loud alarm to alert others to the danger, an important safety feature for user protection.

We answered the customer's remaining questions about the product to conclude this delivery.

자주 묻는 질문 (FAQ)

Q1. What gases can the GasTiger 2000 measure?

The GasTiger 2000 can measure a wide range of hazardous gases — including sulfur oxides, nitrogen oxides, arsine (AsH₃), and hydrogen fluoride — selected from over 40 available gas types, with up to 6 sensor slots supporting up to 7 gases simultaneously.

Q2. Why is arsenic (As) gas dangerous in semiconductor manufacturing?

Arsenic is classified as a Group 1 carcinogen. In semiconductor component disassembly, it can be released in the form of arsine (AsH₃) gas, posing a poisoning risk to workers who are exposed continuously without proper monitoring.

Q3. What preparation is required before using the device?

After powering on, the sensors require approximately one minute to warm up before the device can take accurate gas readings.

Q4. Is operator training available when purchasing the device?

Yes, free hands-on training is available upon request, covering practical operation and safety features for the staff who will be using the device on site.

Q5. What does the fall-detection alarm feature do?

If a user collapses due to gas exposure, the resulting impact triggers a loud alarm to alert others nearby that the user is in danger.
