Air-Met Scientific Pty Ltd offers a range of PID instruments that combine fence electrode and anti-contamination technology to ensure fast, accurate and consistent results, even within challenging humid and dusty environments.
Industrial (or occupational) hygiene places the emphasis on prevention of ill health from work by recognising, evaluating and controlling the risks. Chemicals represent a significant potential source of risk for anyone working with hazardous compounds.
All hazardous chemicals are governed by clearly defined exposure limits. Being able to accurately monitor hazardous chemicals at these concentrations is a vital aspect of industrial hygiene.
Modern PID gas detectors provide reliable detection of over 200 of the most dangerous chemicals, helping to ensure effective industrial hygiene.
Identifying hazardous chemicals
Identifying the types and sources of hazardous chemicals is the first step in industrial hygiene applications. Regular monitoring of locations where the chemicals are stored or used can be performed with handheld instruments or with fixed-in-place detectors that can send the information directly to a control system.
A plant survey might identify possible sources of leaks and emissions that should be monitored with handheld instruments, which can also be used to regularly sweep for ‘hot spots’ or high concentrations.
Some of the more toxic chemicals in industrial use include vinyl chloride, ethylene oxide, styrene, polyols, acrylates and solvents, together with a host of other VOCs. Not all of these chemicals represent the same level of health hazard and not all are carcinogenic.
Depending on the hazard level of each chemical, maximum exposure levels might be set at anything from a few hundred parts per million to under 10 parts per billion.
Choosing the right instrument for the job
It is important to select the right equipment to detect, monitor and control industrial hygiene risk. Photoionisation detectors (PIDs) are proven gas detection instruments in industrial hygiene applications because of their high sensitivity and ability to detect a wide range of organic compounds and various hazardous chemicals at ppb levels.
PID gas detectors also respond to a wider range of compounds, detecting them more reliably and at lower levels than any other detection method.
The Ion Science portfolio of handheld, portable and fixed PID gas detectors rapidly and accurately detects VOCs from 1ppb to 20,000ppm.
