Market-leading hand-held PIDs part of vital equipment on board government body’s ‘first responder’ reconnaissance vehicles.

Ion Science has recently supplied 300 Tiger hand-held volatile organic compound (VOC) detectors to Germany’s Federal Office of Civil Protection and Disaster Assistance (BBK) where they are part of the vital chemical measurement system on board ‘first responder’ reconnaissance vehicles.

VOCs in HAZMAT and the power of PID detection

An emergency response organisation will greatly increase its effectiveness and the level of protection it offers its employees (Responders) by deploying a photoionisation detector (PID).

Incidents Involving VOCs
Many Hazardous Materials incidents involve volatile organic compounds (VOCs), a vast chemical family that is primarily made up of hydrocarbons such as gasoline, alcohols, methane and acetone as well as the BTEX family which include benzene, toluene, ethylbenzene and xylene. Typically, VOCs have a high vapour pressure at ambient temperatures, meaning the liquid gives off vapour that can be readily detected.

Hazardous Materials Spill Response Procedures

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 Hazardous Materials (HAZMAT) response team arrives at the scene of any incident or accident involving hazardous materials there are many unknown factors which initially need to be identified, so it is critical that First Responders tackle each incident in an accurate and systematic way.

The Effects of Humidity During Gas Detection

 

Effects of humidity

The presence of humidity in the sample gas can unfortunately disrupt the measurement leading to inaccurate results. Heated inlets to achieve a stable temperature (typically 50oC) are power hungry and a challenge to achieve in, say a refinery, where stringent intrinsic safety (IS) requirements have to be met.

However, looking at Figure 1, the presence of an additional fence electrode within a PID sensor, can overcome the problem and practically eliminate the effect of humidity. It does this by behaving as a conductive break when there is excess current ow caused by the presence of humidity.

How to bump test and calibrate gas detection equipment

Introduction

ATEX, IEC, British HSE, and US OSHA standards all call for the bump test and calibration of any portable instrument used for worker health and safety protection in a potentially hazardous environment. In order to ensure safety it is necessary not only for the gas meter to read accurately but also to have functional alarms that alert the worker to a hazardous condition. Initial calibration upon receiving the instrument is necessary and, because most sensors can suffer decreased response over time, recalibration will be required.
