Utilizing PIDs for HAZMAT Response

The versatile nature of a PID instrument makes it an indispensable device for emergency services in response to a HAZMAT incident.

Photoionization detector (PID) measures low levels of volatile organic compounds (VOCs), making them a vital tool in the decision-making process following a hazardous materials (HAZMAT) incident. In the immediate aftermath of an accident, chemical spill, or other incidents involving hazardous materials, there are many unknown factors.

The almost instantaneous response of a PID instrument ensures that if conditions change with regard to the disbursement of toxic gas or vapor, the perimeter can be adjusted accordingly. The use of a preliminary personal protective device such as a PID instrument can greatly assist and speed up the decision process in determining the presence of toxic gas or vapors.

When gas or vapor escapes, it disperses and becomes diluted by the air around it and can be difficult to detect. This is where the PID instrument excels, as it has an almost instantaneous response if conditions change with regard to the disbursement of toxic gas or vapor the perimeter can be adjusted accordingly. A PID instrument has the capacity to record information with either positive or negative results at set intervals or continuously.

PID instruments also ensure that First Responders can identify and importantly eliminate any liquids present. After the initial aim of containing the spill, a PID device can then be used to establish the level of contamination of a First Responder themselves. Concentration levels for remedial action are set by individual countries and PID instruments offer a quick and effective way of determining whether an area is now free from contamination or requires further attention. Utilizing PIDs for HAZMAT Response

Hazardous Material spills including biological, chemical and radiological materials pose a serious risk if not promptly and properly responded to by the individuals who initially identify the spill and the appropriate emergency response team. When a HAZMAT team arrives at the scene of any incident or accident involving hazardous materials, first responders tackle each incident in an accurate and systematic way to prevent further increases in risks.

One of the great benefits of PID instruments in a HAZMAT response situation is that while they are not always selective in terms of gas, they are small continuous monitors that provide an immediate response for anyone that uses them. PID instruments are ideal when the threat of a compound’s toxicity is greater than that of its risk of explosion and the accuracy and rate of response are of paramount importance.
