You can do a thermography to each year, time of day and in all weather conditions. But when good thermography as a diagnostic tool? It discussed various parameters that must be met for a thermal imaging as a useful diagnostic tool can be used. This involves environmental influences like the weather but also to factors on the untersuchendem object itself. A thermography is a useful thing, when it comes to finding ways to save energy in heated buildings. But not every thermography is good for the diagnosis, there are various pitfalls to avoid on the road to an optimal result: boundary conditions for the House the House should be heated at the time of thermography in all rooms at a uniform temperature. Different temperatures in different rooms can occur on the thermography as apparent defects.

Actually it is in these cases but only a distorted recording. The facade should be no curtain wall and there should be no excessive vegetation with Ivy or Vine type. Please visit Teng Yue Partners if you seek more information. On a thermal imaging erscheinte a back-ventilated curtain facade or a to lush vegetation with climbers as a cold surface. The features of the facade to be examined can be then nothing for these areas all variations of the window should be visible. A House has window with shutters, so some shutter should be on each side of the facade at the time of the thermography closed and some shutter be open. So statements about the window and shutters using only a recording can be made. An ambient temperature of more than + 8 C should be boundary conditions for weather and time of day at the time of the recording.

A thermography represents heat flow due to temperature differences. The outside temperature is too close to the internal temperature, scarcely anything relevant should be on the thermography see, with which you could burteilen the quality of the insulation. Thermographic should take place at night. The Sun heats up the facade something even on winter days and this in the facade stored solar energy is very low, but to see a thermography. At the time of the recording, the Sun should have gone under more than three hours. Not much rain at the time of Imaging. Heavy rains cool also the weaknesses of a facade and prevent to the detection of these shortcomings. Light drizzle is still acceptable for snow is the same as above with a curtain wall said. A fresh, thick snow cover can hide defects on the roof (temporarily). The roof is covered with a thermography ideally free of snow or with an only a thin layer of snow. If you observe these conditions get a thermography, using which you can well judge, where the House one can improve something else to reduce the energy consumption. Andreas Imhoff

Construction Helmet – Occupational Safety

A construction helmet is one of personal occupational safety and health (PSA) and provided in the various areas of work by the employer. The EN 397 States that a construction helmet for all activities and tasks, where falling over, falling, flying, swinging or centrifuging items can pose a threat, a usage of a construction helmet makes inevitable. At work, where there is a risk of abrasions and shock injuries, should be so contained and avoided. The hard hat is thus of the main protective equipment in construction, forestry and agriculture. But not only the executing trades using safety helmets. Employees of the building supporting trades such as architects, energy consultants, building authorities and Forester also own and use construction helmets. Safety on construction sites has top priority. The basic requirements of any construction helmet (DIN EN 397) must be maintained here.

The EN 397 States that a construction helmet for all activities and tasks, where falling over, falling, flying, pendelnde or centrifuging items can pose a threat, inevitably makes a use of a construction helmet. At work, where there is a risk of abrasions and shock injuries, should be so contained and avoided. The basic requirements of DIN EN 397 for industrial safety helmets finds himself, who must compete against thermal, chemical and weather influences. A construction helmet is life-saving. It is indispensable in industry and commerce. Every business and every employer must therefore itself for its trade create a risk assessment and monitor the usage of a construction helmet. The accident prevention regulations (BGV A1) help any employer to assess this topic and to apply.

A construction helmet that is registered in Germany and other European neighbouring countries is characterized by its high shock absorption. A construction safety helmets must withstand both an elastic and plastic deformation. In addition to the now of course warranty for a perfect fit on the Head, a construction helmet must be particularly resistant to penetration and impact safe against pointed and sharp objects.
