The messy work environment and complicated work flow at the renovation site are often described by the consumers who are decorating as a "terrorist journey." In fact, aside from these complicated renovation procedures, the safety issues at the construction site are the most important ones. Recently, safety accidents due to cluttered materials, untimely collection of tools, and lack of safety protection measures for high-altitude operations have become commonplace. Major decoration companies, consumers, and even guerrillas whose systems are not yet perfect must ensure that safety issues are at the top of the list. Whether they are on-site at the decoration site or due to design or construction failures, the safety hazards caused to the home owners should Timely and effective avoidance. >>> Links: vigilant construction tidiness cut off the three major "resources" 1. Miscellaneous objects in the floor - easy to hurt the body The presence of obsolete materials, exhausted tools, and electric wires, etc., at the scene of the renovation site seem to be only the result of laziness and irregularity. However, once an accident occurs, it will bring us an eternal regret. For example: glass, ceramic chips, broken bricks, nails, screws and other materials, although not large nor heavy, but it can be easily worn through the soles of the shoes, injuring the soles of the feet; used up unused pliers, screwdrivers, chisels or chainsaws If you accidentally fall to the ground, you may stab your body if you step on it or touch it when you come down from a height. 2. Air operations - life threatening without protection The state stipulates that any work performed at a location of 2 meters and over 2 meters is considered as high altitude operations. Work at heights must be erected with scaffolding, belts or other measures to prevent falling. When working on dangerous edges such as roofs and steep slopes, safety nets or protective railings should be installed on the side of the airside and seat belts should be used. Looking closely, these standards also apply to home renovations, especially when ceilings or villas are decorated in high ceilings. Therefore, Zhang Zhigang reminds construction workers, first, that any work that can be done in advance on the ground should be done on the ground as much as possible to minimize working time at high heights; secondly, all kinds of protective measures must be done well, rather Ningdo No less, mainly life safety. 3. Air pollution - the greatest damage to construction workers The long-term work on the construction site full of paint, board, marble, or ceramic materials is ultimately surrounded by various harmful substances, pollutants, and radioactive materials. Although these pollutions are invisible and invisible, they pose a great danger to the human body, but they cause discomfort to the body and danger to life when they are heavy. Therefore, it is recommended that the personnel involved in the construction work should use strict closed treatment after exhausting these materials and properly open windows for ventilation to minimize the damage. 4. Fire hazards - potential lurking anywhere In addition to the quality of decoration, the awareness of fire prevention during construction is also very important. In this regard, Zhang Zhigang put forward five major fire precautions in the decoration process. The paint is placed alone and thrown away. At the construction site, paint is always the most dangerous combustible. Barrels of paint, even buckets that had been painted, were all met with fire. Therefore, all paints should be placed together in a single place, near the window, or on the balcony; paint buckets that are not used or temporarily not used should be sealed in time to avoid touching the open flame; ignition of abandoned paint buckets should be timely Deal with it so that it will be used up, leaving no hidden dangers. Construction workers are prohibited from using electric stoves and heat faster. During the construction process, it is best not to lose money for natural gas in your home to prevent workers from cooking. However, the use of simple electric appliances such as electric stoves, fast heat, and electric dumplings is strictly forbidden. Otherwise, once workers forget to switch off, the consequences will be unthinkable. In addition, it is recommended that formal decoration companies provide workers with more formal appliances such as drinking fountains and electric kettles. No open fire is allowed on the construction site. All decoration companies have stipulated that no open fire can occur on the construction site and heavy penalties will be imposed upon discovery. Consumers should also pay attention to this point. Do not smoke when supervising the construction site. In addition, try to choose a regular decoration company, some rules guerrillas can not be guaranteed. Equipped with fire fighting equipment. Relevant departments require that the construction site must be equipped with appropriate fire-fighting equipment in case of emergency. Consumers can check this point at any time. Do not connect more than 100 watt bulbs during construction. During the renovation period, the lamps left at home can withstand a maximum of 100 watts, but due to the need for a bright working environment during construction, some workers will privately connect 100 watt or more bulbs to the lamp. As a result, there is a possibility that the current will not be able to load because of the current. If this happens, consumers are required to request the construction unit to replace porcelain lamps that can withstand higher currents to avoid danger.

The pipette tip is a single empty 1000 ul pipette tips,200ul pipette tips,10ul pipette tips,low retention pipette tips Yong Yue Medical Technology(Kunshan) Co.,Ltd , https://www.yypcrtube.com
Cavity reservoir; the pipette uses the principle of air displacement and controls the maximum displacement of the piston by rotating a screw with an ultra-fine thread
displacement, and then control the amount of liquid suction. There are the following problems when using the above kit for suction: 1. The suction volume is controlled by the pipette
After the pipette is sterilized or used for a period of time, it is easy to cause "hidden" failures, which cause the operator to be difficult to detect.
The actual suction volume is inaccurate, and it needs to be adjusted frequently, and the operation is cumbersome and time-consuming; 2. To improve the pipetting accuracy, the operator's
The operation requirements are high, and it is easily affected by factors such as the suction speed, the depth of the tip below the liquid level, and the inclination angle of the pipette.
The actual suction volume will be heard; 3. The actual suction volume will be affected because the suction head cover is not tight and leaking, and it will not be easily detected; 4.
When performing experiments that require high accuracy, such as analysis, in the operation of equal volume aspiration of liquids with different densities, the actual
The actual suction volume will be affected by the density itself; 5. In order to improve the accuracy, this type of pipette needs to carry out high
Cost-optimized design results in extremely high pipette costs.
