What are the potential safety hazards in maintenance posts and the safety precautions that can be taken?

Potential safety hazards existing in maintenance posts and safety measures that can be taken. What maintenance posts are divided into several categories: electronics, machinery, communications, and municipal administration.

The safety hazards of electronic products generally include electrical and fire hazards. First of all, operators should be protected from electric shock and equipped with an insulated operating environment. In addition, they also need to prevent short-circuit accidents, damage devices and cause accidents, have professional knowledge of circuit operation and related detection devices, and provide post-accident protection.

Hidden dangers of mechanical safety: water, electricity, fire, personal safety, etc. First of all, you need to wear relevant tooling and have professional knowledge and qualification certificate related to mechanical maintenance. Secondly, fire prevention, drainage and waterproof measures should be in place.

Communication: electricity, fire, personal safety, etc. , must strictly implement the operating procedures, operate in accordance with the operating procedures, any security risks need to be eliminated before maintenance, and equipped with security officers for patrol inspection.

Municipal: electric power, fire protection, personal safety, etc. First of all, you should have relevant operating qualifications, secondly, security personnel should eliminate all potential safety hazards, and in addition, you should be equipped with relevant hedging tools.

Potential safety hazards of infusion pumps and countermeasures There are two kinds of risks in infusion pumps used in China:

(1) There are many brands and varieties of infusion sets, which are easily confused when used in infusion pumps. The solution is: the infusion pump displays the brand, variety or registration number of the consumables used to ensure no confusion; Mandatory inspection of consumables; The switching operation of consumables is convenient.

(2) Domestic infusion sets are all cheap PVC plastic pipes, which are easy to cause fatigue fracture of materials or collapse (collapse) of pipes when used in infusion pumps, and the accuracy and safety cannot be guaranteed. The solution is to store the fatigue point of each consumable. When the consumable is close to the fatigue point due to long-term infusion, the infusion pump will give an alarm to remind the operator to move the extrusion position to avoid fatigue rupture and fatigue collapse of the consumable.

What preventive measures can teenagers take in the face of potential safety hazards around them? Three short stories: Many years ago, a father and a mother wanted to go on holiday, so they decided to go to town at night. They invited the people they trusted most to look after the children. When the nanny came, even their children had fallen asleep in bed. So the nanny just checked whether the child slept well and sat down.

Late at night, the nanny felt bored and wanted to go downstairs and watch TV. But she can't watch it because there is no TV downstairs (because parents don't want their children to watch too much garbage). She called the children's parents and asked if they could watch TV in the bedroom. Of course, the parents of the child agreed.

But the nanny wants one last request.

She asked if she could cover the clown statue with a blanket or clothes, because it scared her.

There was a silence on the phone for a while.

(At this moment, Dad is talking to the nanny. )

He said, Take the children out of the room. ...

We'll call the police ... we've never seen a clown statue.

That clown is probably a murderer who escaped from prison.

There was silence on the phone for a while.

(The father of the child who is talking to the nanny) said: Take the child out of this house ... we will inform the police ... we don't have a clown statue. ...

Children and nannies were murdered by clowns.

The clown turned out to be a murderer who escaped from prison.

If you don't forward this post within 5 minutes, this clown will stand in front of your bed with a knife at 3 am.

I made a fortune here, which is why the demon clown didn't kill me.

What are the hidden dangers and preventive measures in junior high school classroom? When studying physics, we should attach great importance to experiments and pay attention to observing physical phenomena in nature and experiments. Physical phenomena are the basis of producing physical knowledge. Without understanding the relevant physical phenomena, it is difficult to have a deep understanding of physical knowledge. Physics experiment teaching is different from concept class teaching. The teaching of experimental class not only requires students to master the laws of physics, but more importantly, it is to cultivate students' practical ability, scientific literacy and the ability to find problems, ask questions and guess boldly. Analyze experimental phenomena and experimental data with a scientific attitude of seeking truth from facts, and draw experimental conclusions.

However, in the process of physics experiment teaching, safety is very important. In the process of physics experiment, the danger of explosion, fire, poisoning, burns, cuts, electric shock and other accidents is often hidden. How to prevent these accidents and how to rescue them when they happen? These are the qualities that every junior high school physics teacher must have. Through years of teaching practice, combined with the characteristics of junior high school physics teaching, I summed up the common sense of safe use of electricity and how to use instruments and equipment safely in the experiment process, to improve students' safety awareness and strengthen self-protection measures, so that every student can grow up safely and healthily.

First, the common sense of safe electricity use

Illegal use of electricity often leads to serious accidents, such as personal injury, fire and equipment damage. There are many electrical equipment in physics laboratory, so we should pay special attention to the safety of electricity use. Students should try to use safe voltage (≤36v) instead of safe voltage in electrical experiments. If it cannot be replaced, it is necessary to explain the correct operation methods and precautions to students, and educate students to abide by the laboratory safety management system to prevent accidents.

1, to prevent electric shock

(1) Don't touch electrical appliances with wet hands.

(2) The * * * part of the power supply should be insulated (for example, the wire connector should be wrapped with insulating tape).

(3) The metal shell of all electrical appliances has grounding protection.

(4) During the experiment, the circuit should be connected first, and then the power supply should be connected. At the end of the experiment, the power supply should be cut off first, and then the line should be disconnected.

(5) When repairing or installing electrical appliances, cut off the power supply first.

(6) Do not test the high voltage with a pencil. The use of high-voltage power supply should have special protection measures.

(7) If someone gets an electric shock, cut off the power supply quickly, and then carry out rescue.

2, to prevent fire

(1) The fuse used shall be consistent with the electricity consumption allowed by the laboratory.

(2) The safe power of wires should be greater than the total power consumption.

(3) If there are flammable and explosive gases such as hydrogen and gas indoors, electric sparks should be avoided. When the relay switches, it is easy to produce electric sparks, so be especially careful. When electrical contacts (such as electric plugs) are not in good contact, they should be repaired or replaced in time.

(4) When the wire is on fire, immediately cut off the power supply, and use sand or carbon dioxide and carbon tetrachloride fire extinguishers to extinguish the fire. Do not use water or conductive liquid such as foam extinguisher to extinguish the fire.

3, to prevent short circuit

Potential safety hazards and rectification measures: sundries are piled up in the corridor, fireworks are set off in the community, the speed of some communities is too fast, and the streets in the community are too narrow;

Measures: popularize fire prevention knowledge in the community and enhance residents' self-safety awareness; Speed limit in the community, the property broadens the driveway of the community.

What safety precautions should be taken in dike construction? Punishment should be decided according to specific reasons.
