3.3. When working with a spirit lamp, protect clothing and hair from ignition, do not light one spirit lamp from another, do not remove the burner with a wick from a burning spirit lamp, do not blow out the spirit lamp flame with your mouth, but extinguish it by covering it with a special cap.

3.4. When heating a liquid in a test tube or flask, use special holders (tripods), do not point the opening of the test tube or the neck of the flask at yourself and your comrades, do not bend over the vessels and do not look into them.

3.5. Be careful when handling laboratory glassware and glassware, do not throw, drop or hit them.

3.6. When preparing preparations for examination under a microscope, carefully take the coverslip with the thumb and forefinger by the edges and gently lower it onto the slide so that it lies freely on the preparation.

3.7. When using solutions of acids and alkalis, pour them only into glassware, avoid contact with skin, eyes and clothing.

3.8. When working with solid chemical reagents, do not take them with unprotected hands, in any case do not taste them, collect them for the experiment with special spoons (not metal ones).

3.9. To avoid poisoning and allergic reactions, do not smell plants and mushrooms, do not taste them.

4. Labor protection requirements in emergency situations

4.1. When spilling flammable liquids or organic substances, immediately extinguish the open flame of the spirit lamp and inform the teacher (teacher) about it, do not clean up spilled substances on your own.

4.2. In the event that laboratory glassware or glassware breaks, do not collect their fragments with unprotected hands, but use a brush and a dustpan for this purpose.

4.3. In case of injury, inform the teacher (teacher) who will provide first aid to the victim, inform the administration of the institution about it, if necessary, send the victim to the nearest medical institution.

5. Labor protection requirements at the end of work

5.1. Tidy up the workplace, hand over to the teacher (teacher) equipment, instruments, tools, preparations, chemicals.

5.2. Waste aqueous solutions of reagents should not be drained into the sewer, but into a closed glass vessel with a capacity of at least 3 liters with a lid for their subsequent destruction.

5.3. Ventilate the room and wash hands thoroughly with soap and water.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner.

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

New small craft tracking technology 09.06.2014

The creator of the ship positioning system (AIS), exactEarth, announced the creation, together with the equipment manufacturer SRT Marine Technology (SRT), of a new ABSEA position monitoring system for small vessels and the launch of the exactAIS Trax service. In many ways, a revolutionary new product will help solve the problem of tracking millions of small vessels in the vast oceans.

Graham Stickler, vice president of exactEarth, said, “A huge number of small boats are now spending most of their time out of sight of shore services. With the help of the new ABSEA AIS devices and the exactAIS Trax service, it is possible to achieve high accuracy in determining the position of vessels. We believe that the new vessel traffic management system will provide a higher level of safety for all participants in maritime traffic."

The new system is based on ABSEA technology, which for the first time uses low-power transceivers for satellite monitoring. Small AIS transmitters do not require large power supplies, wired connections or any other vessel modifications.

The transceiver is battery powered and can work with existing AIS satellite constellation. An innovation is the exactAIS Trax service, which provides the possibility of global monitoring of any ships, regardless of their displacement and distance from AIS shore receivers.

In addition to ensuring maritime safety, the new exactEarth system will provide an unprecedented map of the global maritime transport system, updated in real time. In addition, the new generation of AIS can store a history of each ship's movements, making it easier to analyze the data it collects. This information can be useful for analytical geographic information systems used for scientific research, logistics, crime control or military affairs.
