MEASURING CARCINOGENS<br />
STRICT REQUIREMENTS FOR<br />
WORKPLACE MONITORING<br />
Requirements for detection processes<br />
• The detection system must be sensitive<br />
and precise enough to reliably detect<br />
concentr<strong>at</strong>ions in the range of under 1 ppm.<br />
• Test results must be conclusive within the<br />
shortest amount of time possible, typically<br />
within a few minutes.<br />
• The detection system should essentially be<br />
free of cross sensitivities.<br />
Requirements for detection performance<br />
• The sensitivity of the testing device must<br />
comply with the l<strong>at</strong>est requirements. In the<br />
case of carcinogenic substances, this is even<br />
more critical in the low measuring ranges.<br />
• When a pump is used, the quality of the<br />
hose is particularly important. If the pump<br />
hose is made from a m<strong>at</strong>erial in which<br />
deposits of the measured substances might<br />
form, it can distort the test results.<br />
SUITABLE MEASUREMENT METHODS<br />
Ongoing methods are most suitable for<br />
workplace monitoring in hazardous situ<strong>at</strong>ions,<br />
such as measurement with a non-selective<br />
OV sensor (OV = organic vapour) or a<br />
PID sensor. Where there is any doubt, a<br />
selective measurement can then be taken.<br />
For timepoint-rel<strong>at</strong>ed analysis, regular spot<br />
measurements using a selective measuring<br />
method would be a typical approach. To better<br />
assess the risks within the context of a hazard<br />
assessment, workplaces can also be controlled<br />
<strong>at</strong> irregular intervals. These selective spot<br />
measurements methods need to be precise in<br />
low ppm or even ppb ranges. The measuring<br />
d<strong>at</strong>a should be very easy to read, interpret<br />
and, if possible, further process in software<br />
solutions.<br />
Requirements for document<strong>at</strong>ion<br />
• The measurement results generally need to<br />
be documented, assessed, and archived by<br />
the employer.<br />
CLOUD BASED DOCUMENTATION<br />
Through the use of cloud-based<br />
solutions d<strong>at</strong>a exchange from various<br />
sources, such as measured values from<br />
authoris<strong>at</strong>ion measurements, people<br />
in the workplace, work assignments,<br />
company doctor examin<strong>at</strong>ions etc.<br />
will become far easier to aggreg<strong>at</strong>e,<br />
evalu<strong>at</strong>e and document.<br />
The result: seamless job overviews,<br />
resulting in fast decisions and high<br />
working efficiency.<br />
