According to 94/9/EC, a device that is to be used in an environment at risk of explosion may only be brought into the market if it satisfies the standards specified in the norm.
Compared with the previous directives, it must be noted that the specification refers not only to electrical but also to mechanical equipment (e.g. cylinders).
Devices are divided into categories and groups to accurately define the conditions of use. This definition is marked on the device and may appear as follows:
Fig: Symbols representing in Equipment Marking
Device Groups:
There are 2 groups of devices. Devices of Group I, Category M are for use in underground mines and their above-ground equipment, which are at risk from firedamp and/or inflammable dust. All other areas at risk of explosion are combined in Device Group II.
Identifier:
EEx defines that this is an electrical device.
Ignition protection class:
This defines which measures are used to ensure explosion protection. The following ignition protection classes are used: m = Encapsulation, ia = Intrinsic safety, c = Safe by design Other ignition protection classes are defined in EN 50014: 1997. It should be noted that devices in ignition protection class ia may only be supplied from circuits that are certified to be intrinsically safe.
Explosion group:
Device group II is sub-divided into Explosion Groups A, B or C. This classification is dependent on the typical material properties of the gases and vapors that occur. The hazard level of materials increases from Explosion Group IIA to IIC. The requirements for the devices increase accordingly. If a device is approved for IIC, it can be used for all other explosion groups. Alternatively, the chemical formula or the name of the material can be stated here.
Temperature class:
It must be ensured that the ignition temperature of an inflammable material is not reached during operation. For this purpose, the maximum surface temperature of a device must be less than the minimum ignition temperature.
For this reason, the maximum surface temperature of equipment for use with inflammable gases, vapors or mists is specified in temperature classes. For dusty environments, the maximum surface temperature is specified in °C.
Temperature class
The maximum permissible surface temperature of the equipment (°C)
T1
450 °C
T2
300 °C
T3
200 °C
T4
135 °C
T5
100 °C
T6
85 °C
Category:
The categories define which zones the devices may be used in. The classification states how frequently and in what concentration the ignitable mixture occurs. Furthermore, differentiation is made as to whether the hazard is due to gases, vapors and mists or due to dust.
Category 1:
For devices, which guarantee a very high level of safety. Intended for the case where an atmosphere at risk of explosion is to be expected frequently or continuously. Devices in this category can also be used in Category 2 and 3.
Inflammable gases, vapors or mists
Zone 0 equivalent to Category 1G
Area in which an atmosphere at risk of explosion as a mixture of air and inflammable gases, vapors or mists is continuously or frequently present or present for long periods.
Inflammable dusts
Zone 20 equivalent to Category 1D
Area in which an atmosphere at risk of explosion in the form of a cloud of inflammable dust contained in the air is continuously or frequently present or present for long periods.
Category 2:
For devices, which guarantee a high level of safety. Intended for the case where an atmosphere at risk of explosion is to be expected. Devices in this category can also be used in Category 3.
Inflammable gases, vapors or mists
Zone 1 equivalent to Category 2G
Area in which an atmosphere at risk of explosion as a mixture of air and inflammable gases, vapors or mists can form occasionally during normal operation.
Inflammable dusts
Zone 21 equivalent to Category 2D
Area in which an atmosphere at risk of explosion in the form of a cloud of inflammable dust contained in the air can form occasionally during normal operation.
Category 3:
For devices, which guarantee a normal level of safety. Intended for the case where an atmosphere at risk of explosion is to be expected rather infrequently and, if so, for only short periods.
Inflammable gases, vapors or mists
Zone 2 equivalent to Category 3G
Area in which an atmosphere at risk of explosion as a mixture of air and inflammable gases, vapors or mists does not normally occur at all or only for short periods during normal operation.
Inflammable dusts
Zone 22 equivalent to Category 3D

Particulate matter (PM) is a particle pollution, which is produced in a great number of ways that can be classified into either mechanical or chemical processes. Traditionally, the environmental sciences have divided particles into two main groups PM10 and PM2.5. PM10 is particles between 2.5 and 10 microns (micrometers) in diameter (a human hair is about 60 micron in diameter).
PM2.5 is particles smaller than 2.5 microns. PM2.5 and PM10 have different material compositions and can come from different places. The smaller the particle the longer it can remain suspended in the air before settling. PM2.5 can stay in the air from hours to weeks and travel very long distances because it is smaller and lighter.
PM2.5 can get down into the deepest (alveolar) portions of the lungs when the gas exchange occurs between the air and your blood stream. These are the most dangerous particles because the alveolar portion of the lungs has no efficient means of removing them and if the particles are water soluble, they can pass into the bloodstream within minutes. If they are not water soluble, they remain in the alveolar portion of the lungs for a long time.
When the small particles go deeply into the lungs and become trapped this can result in lung disease, emphysema and/or lung cancer in some cases.
The main effects associated with exposure to particulate matter may include: premature mortality, aggravation of respiratory and cardiovascular disease (indicated by increased hospital admissions and emergency room visits, school absences, loss of work days, and restricted activity days) aggravated asthma, acute respiratory symptoms, chronic bronchitis, decreased lung function and increased myocardial infarction.
There are many varieties of particulate pollutants in our homes and offices. Ones from outside include industrial sources, construction sites, combustion sources, pollen, and numerous others. Particles are also generated by all kinds of normal indoor activity ranging from cooking, walking across the carpet, your pets, sofa or beds, air conditioners etc. Any movement or vibration can create airborne particles!
How to improve air quality in your home and office:
The first thing you need to do is monitoring your indoor air quality every day. The monitoring information will let you evaluate the indoor air quality.
The IAQ -PM2.5 will let you know if the steps you are taking to improve your air quality are really working or not especially let you know if a $500 air purifier works any better than a $200 one. This will really help you to save money.
The concentration of PM2.5 probably has much difference due to the different purpose of the rooms.
The most effective way to improve indoor air quality is, detecting each room and treatment of air purification for the important rooms, such as living room and bedrooms.
IAQ -PM2.5 supply you a real-time and accurate information, it can help you to be sharp-eyed and clearheaded.
Please make sure the filters of indoor HVAC systems are clean, otherwise, need to clean or replace filters. The unclean filter is one of the sources of indoor particle pollution.
Please notice it’s very important for the quantity and location of air purifiers or air cleaners. Now you need the help of the real-time monitor information of PM2.5 by IAQ-PM2.5.
Models IAQ -PM2.5-300H: PM2.5 Indicator with temperature & RH, 6 colors backlit LCD IAQ -PM2.5-340H: PM2.5 Indicator with temperature & RH, 6 colors backlit LCD. Modbus RS485 interface

Carbon dioxide (CO2) is the second main gas responsible of the greenhouse effect and the major gas discussed during environmental summits. It is mainly used, according to its state:
Under its solid state, carbon dioxide (CO2) is used as a cool pack.
Under its gaseous state, it is used in the beer brewing and the wine growing
Under its liquid state, carbonic gas is used to charge efficient extinguishers against any type of fire.
It is the result of complete combustions, both natural (volcanic eruptions, fire, etc.) and anthropogenic (car engine combustion, industry combustions, etc.)
Naturally present in the atmosphere at low concentration, carbon dioxide (CO2), also known as carbonic gas, remains hazardous. As it is essential for photosynthesis, it can be found in greenhouses to increase plant growth.
EFFECTS OF CARBON DIOXIDE ON HEALTH
FEATURES OF CARBON DIOXIDE
The carbonic gas is colourless in the visible light but absorbing in the infrared spectrum, and such is responsible of the greenhouse effect.
Odourless, non-flammable and non-toxic, carbon dioxide (CO2) is produced in the body and eliminated in the lungs.
Nevertheless, the carbonic gas features asphyxiating properties. As it is heavier than the air it is present in the poor ventilated locations (confined spaces) like tanks, sewers, holes…
