An Assessment of the Impact that Gas Monitoring Practices Can Have on “Cost of Ownership” and “Return on Investment”
Consideration and discussion are devoted to the notion that “gas monitoring instrumentation should be treated just like any other piece of lifesaving equipment…”1. This is especially true for the semiconductor, photovoltaic, and gas manufacturing industries, where even the tiniest of impurities can wreck economical havoc on a plant, including loss of product, equipment damage, ...

Taiwan Indoor Air Quality Management Act
On 8 November 2011, the Taiwanese Legislative Yuan passed the Indoor Air Quality Management Act making Taiwan the second nation after Korea to implement an indoor air quality management act. For accurate understanding of indoor air quality, it is advised to simultaneously monitor multiple indoor air quality parameters including gases, temperature and humidity. PPM Technology’s range of IAQ ...

H&S Operational Efficiency: Plant turnaround
Hazardous chemicals that pose a risk to humans are normally safely transported within the process but obviously during plant turnaround this is no longer the case. As lines and reaction vessels are opened they pose a significant risk of over-exposure, without appropriate control measures. Concentrations can be several hundred (or even thousand) times higher than the occupational exposure ...

10 Commandments of Indoor Air Quality (IAQ)
Indoor Air Quality (IAQ) relates to a number of environmental factors inside a building that can impinge on the health, comfort, or work performance of the building’s occupants. Monitoring IAQ is vital because it is estimated that the average person spends 90% of their time breathing “indoor air”. PPM Technology and our partners Hinds International have identified ‘10 ...

Bottom–up monitoring of municipal energy and climate policy: more than an alternative to top–down approaches?
Policy evaluation is widely considered important for assessing policies for effectiveness and impact. Municipalities are among the political actors implementing energy and climate policy. Yet, few municipalities have introduced adequate instruments to monitor the effectiveness of their actions. Often, municipal actors consider local greenhouse gas (GHG) inventories to be sufficient to monitor the ...

Extension of the agency’s monitoring certification scheme MCERTS to include continuous ambient air quality monitoring instruments
ABSTRACT The Environment Agency launched its Monitoring Certification Scheme MCERTS for continuous emission monitoring systems (CEMs) for industrial stacks at CEM98. At the time the Agency referred to its plans to broaden the Scheme later to include other monitoring activities. This paper presents details of the proposed extension of MCERTS to cover continuous ambient air quality monitoring ...

Benzene Health Issues: Leading & Lagging Indicators
Leading and lagging indicators Health surveillance by conducting a urinary test or blood count can of course show evidence of exposure but these are lagging indicators i.e. after exposure has already taken place by which time damage may have been done. A preferable leading indicator for benzene exposure would be to monitor using a real-time monitoring instrument such as a ...

Double benefit of monitoring Indoor Air Quality (IAQ)
It is a difficult balance to save money and energy yet maintain a comfortable and healthy indoor air environment. A logical solution to controlling indoor air pollution is good ventilation coupled with IAQ monitoring using gas sensors. This can ensure healthy indoor air as well as a more efficient HVAC system. Typical IAQ investigation and examination consists of taking single-point ...
