2.12.14. With a suspension height of luminaires up to 5 m, their maintenance from ladders and step-ladders is allowed. If the luminaires are located at a higher height, their maintenance from overhead cranes, stationary bridges and mobile devices is allowed, subject to the safety measures established by the safety rules for the operation of electrical installations and local instructions.

2.12.15. Broken fluorescent lamps, DRL lamps and other sources containing mercury should be stored in a special room. They must be periodically taken out for destruction and decontamination to the places designated for this.

2.12.16. Inspection and testing of the lighting network should be carried out at the following times:

2.12.17. Checking the condition of stationary equipment and the electrical wiring of emergency and working lighting, testing and measuring the insulation resistance of wires, cables and grounding devices should be carried out when the electric lighting network is put into operation, and then according to the schedule approved by the Consumer responsible for the electrical economy, but at least once a three years. The measurement results are documented in an act (protocol) in accordance with the standards for testing electrical equipment (Appendix 3).

2.12.18. Maintenance and repair of outdoor (street) and advertising lighting installations must be carried out by trained electrical personnel.

Users who do not have such personnel can delegate the maintenance and repair of these installations to specialized organizations.

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of ​​controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog ​​owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Random news from the Archive Brain cells exchange batteries 06.08.2016 The transmission of nerve impulses requires a lot of energy, so it is not surprising that many mitochondria sit in neurons - special organelles that are called the power stations of the cell. Outwardly, mitochondria look like membrane tanks, but inside and at the molecular level they are very complex: they are literally stuffed to capacity with a variety of enzymes that, with the help of oxygen, extract energy from the chemical bonds of various substances and convert it into the form of an ATP molecule - in this form, the energy of the cell easy to store and easy to use. Mitochondria have their own DNA and can divide on their own, so there is no problem with their number. However, they, like everything else, wear out, age, cease to perform their functions as they should. And then the neuron simply gets rid of them: in 2014, an article was published that described how neurons “spit out” mitochondria that have become useless and how they are immediately absorbed by the service cells of the nervous system, astrocytes, whose task is to provide neurons with favorable conditions for work, in including removing a variety of molecular and cellular debris. And then En Lo (Eng Lo) and Kazuhide Hayakawa (Kazuhide Hayakawa) from the General Hospital of Massachusetts thought that maybe the opposite is happening - that neurons can not only spit out mitochondria, but also absorb them into themselves. Moreover, even earlier, something similar was found in bone marrow stem cells and lung cells: under severe stress - for example, due to a wound - stem cells, being next to lung cells, give them their mitochondria. If neurons really take foreign mitochondria, then this happens at a difficult moment for them, in case of damage, illness, etc. As we said, the conditions for work and well-being of neurons are provided by astrocytes, which feel if their wards are ill. The immune protein CD38 is a wake-up call, and when mice were genetically engineered to overproduce CD38, the mice's astrocytes could be observed releasing their own normal, healthy mitochondria into the environment. The nutrient fluid, together with the “spit out” mitochondria, was then transferred to the dying neurons, which absorbed them during the day, gradually coming to their senses: the neurons had more energy (literally, in the form of ATP molecules), they lived longer and even formed new processes .
