5. Thirty safety tips

1. Restaurant, to create a quiet and warm environment for children, it is best not to watch TV in the restaurant. Avoid children eating food by mistake because of emotional excitement.

2. Don't leave all power cords lying around, especially not hanging down. Putting it on the ground will trip the child, which is more dangerous in the air and may strangle the child.

Family fitness equipment should be put in the room where children can't get in. Don't let children accompany you during exercise, and make sure that all instruments have locking devices. Unplug the power supply during exercise, and the moving parts should be sealed tightly.

4. All cabinets in the kitchen should be locked, and kitchen utensils such as knives and forks should be placed in cabinets or drawers and locked. Prevent children from opening it. Because it contains many children's "dangerous goods", such as medicines, various washing supplies, as well as sharp tools such as scissors, knives and forks.

5. The refrigerator door should also be locked, not for fear that children will steal food, but for fear that curious children will open the refrigerator door casually and get hurt or cut their hands by objects when taking things. Especially those big refrigerators, should be locked up.

This stove is very dangerous for children. If he turns on the gas switch or touches the hot pot ... imagine the pain. Therefore, it is necessary to add a protective cover in front of the stove, and turn the long pot handle to the back of the stove, facing the wall, not the side where people stand, to prevent children from reaching for burns.

7. When the bathtub is not in use, don't accumulate water to prevent children from drowning.

8. In the space where the child is located, the ground should be kept dry and not slippery, and anti-slip mats should be placed in the bathroom, in front of the washbasin and on the stairs.

9. Most children are interested in toilets. Children around one year old like to play with the water in the toilet, and it is easy to lose their balance and fall into the toilet. Two or three-year-old children like to throw all kinds of things into the toilet, and then pump water to observe their changes, which leads to the blockage of the toilet. Throwing valuables into the toilet may cause family property losses. Therefore, all toilets in the house should be covered with a top cover and then locked with a toilet lock. If you can't lock the toilet, you'd better lock the bathroom door to prevent children from running to the toilet without your knowledge.

10. Electrical appliances such as hair dryers, hair dryers and electric irons are often used. After use, cut off the power supply in time to prevent children from getting an electric shock due to touch.

1 1. If conditions permit, it is best to use cordless phones in children's activity spaces. It is very convenient for a child caregiver to take care of children when they are on the phone, especially when children are in the kitchen or bathroom. In addition, cordless phones can prevent children from tripping over telephone lines or receiver lines.

12. In order to prevent suffocation, don't let children sleep and play on waterbeds, sofa cushions and bean bag chairs (with small balls as fillers, the shape can change with the body).

13. Let the child develop the habit of sleeping face up, choose a hard mattress for him, and don't spread plastic on the child's mattress.

14. Never leave a child alone at home, even if he is asleep.

15. Children's beds should be equipped with guardrails. Children under 6 years old can't be arranged in the upper berth.

16. A guardrail must be installed outside the window of the children's room (or ensure that the window is not easy to be opened by children).

17. Keep the thermos or water dispenser at home out of the reach of children.

18. It is best to install smoke alarms and carbon monoxide meters at home.

19. Put the plants at home, whether poisonous or not, on a high shelf where children can't reach them. Eating by mistake will lead to poisoning. In particular: ivy, oleander, heart leaf ginger, calla lily and other toxic plants should pay special attention.

20. If there are stairs at home, the distance between stair railings should ensure that children can't get out. It is best to have a safety door at the upper and lower entrances of stairs.

2 1. Manage the medicines at home like your own gold and silver jewelry and put them in a locked drawer or box.

22. Chemicals that children cannot touch (alcohol, gasoline, detergents, pesticides and alcohol, etc.). ) be specially preserved. Don't put detergents and cleaning agents on the ground to prevent children from eating by mistake. Never put these things in a drink bottle.

23. Always tidy up the space and eliminate dangerous factors, such as rolled carpets, bare wires, the distance between railings, and whether there are deposits or wet liquids on the corridor floor.

24. Make sure there are no stools and tables to climb on the windowsill. Don't put furniture such as cradles by the window.

25. Use the protective cover of the safe electric socket to prevent children from touching their fingers or toys out of curiosity.

6. How to manage hazardous chemicals

Original publisher: Sonny Honnore.

1. Objective To clarify the safety requirements for transportation, handling, storage, use and disposal of hazardous chemicals. 2. It is applicable to the safety management during the transportation, loading and unloading, storage, transfer, use and scrapping of hazardous chemicals in our company. 3. Responsible departments: Purchasing Department, Production Department and Quality and Safety Department. 4. Procedure 4. 1 Definition of dangerous goods All articles that are flammable, explosive, corrosive and toxic and will cause personal injury and property loss are dangerous goods. 4.2 Transportation and transit of hazardous chemicals 4.2. 1 Transportation of hazardous chemicals must comply with relevant national traffic regulations and go through relevant transportation procedures.

7. Learning experience of hazardous chemicals

I don't know exactly what subject you are training.

So I only provided some knowledge about dangerous chemicals, hoping to help you! The particularity of hazardous chemicals determines the existence of unsafe factors in production, management, storage, transportation and use. In the course of operation, the purchase and sale of hazardous chemicals and the storage, transportation and waste disposal around the purchase and sale operation are not only business activities, but also the safety management of hazardous chemicals.

If the characteristics of dangerous chemicals are not clear, it will cause personal injury, property loss, environmental pollution and even extremely bad political influence. Accidents in operation: For example, on August 5th, 1993, the Qingshuihe chemical dangerous goods warehouse of Shenzhen Anmao Company exploded.

The explosion caused a fire, and a second strong explosion occurred in the fire area after 1 hour, causing extensive damage and fire. 15 people died and more than 200 people were injured, including 25 seriously injured, resulting in a direct economic loss of 250 million yuan.

Cause of fire and explosion: The mixed ammonium persulfate and alkali sulfide (strong oxidant and reducing agent) in No.4 warehouse of dry goods warehouse have a fierce redox reaction due to contact, forming heat accumulation, which leads to fire and combustion. The combustion of No.4 warehouse ignited a variety of combustible substances in the reservoir area, and the air temperature in the reservoir area rose, making a variety of dangerous chemicals in a heated state.

About 30 tons of organic flammable liquid stored in No.6 warehouse was heated above the boiling point, which broke through the packaging and quickly volatilized, forming an explosive mixture with air and flue gas and causing an explosion. The explosion released huge energy, and there were flashes and fireballs, which triggered the second explosion of nitric acid electroplating stored in the warehouse and formed mushroom-like clouds.

According to experts, the main reason for the accident was that the Qingshuihe dry goods warehouse was illegally converted into a hazardous chemicals warehouse, and the storage of hazardous chemicals was seriously illegal. The direct cause of the accident was the contact between oxidant and reductant in No.4 warehouse of dry goods warehouse.

This is a liability accident, and the lesson of the accident is painful. Another example is September 9, 20001year. Just before the Mid-Autumn Festival, a chemical business department in Yulin City, Guangxi mistakenly sold 2.5kg of sodium cyanide as a food additive calcium chloride.

The central and local authorities attached great importance to this matter, and formed a special investigation team to investigate and recycle the missold sodium cyanide. Accident during storage: 1989 August 12, the oil tank in the old tank farm of Qingdao Huangdao Oil Depot was struck by lightning and caught fire, resulting in19 deaths and 78 injuries.

Accident during transportation:1April 5, 1972, Shanxi Jiaocheng Chemical Fertilizer Plant 1.2t liquid ammonia tanker exploded at the gate of Zhao Supply and Marketing Cooperative in Qixian County, causing 2 1 person to die and 155 person to be poisoned. The main reason is the poor quality of fuel tank and illegal parking.

On September 3rd, 199 1, a 2.4t(98%) methylamine tanker leaked in shaxi town, Shangrao, Jiangxi Province, poisoning 595 people, including 37 people who died and polluting 230,000 square meters. The main reason is illegal driving.

200 111October1,a Dongfeng motor with an approved load of 8 tons was loaded with 1 1.67t liquid sodium cyanide (with a content of 30. When the car turned into Xinghua River, the tank fell down and the tank mouth was broken. About 65,438+00 tons of sodium cyanide leaked into the river, causing serious water pollution.

After the accident, the relevant departments of the State Council quickly rushed to the scene of the accident to guide the investigation and pollution control. Luoyang City, Henan Province quickly set up an accident rescue headquarters, invited experts to give on-site guidance, and adopted a scientific rescue plan of "preventing, breaking, eliminating, blocking and detecting".

After five consecutive days of fighting, * * * dispatched more than 3,000 officers and men of public security, fire protection, environmental protection, sanitation, water conservancy, garrison and armed police, used more than 60 large-scale mechanical vehicles, used 94 tons of sodium hypochlorite, 28 tons of bleaching powder and more than 350 tons of quicklime, effectively controlling the spread of pollution. Accidents during use:1993 65438+1On October 29th, 7 tons of benzoyl peroxide exploded in the warehouse of Zhengzhou Food Additive Factory, killing 27 people and injuring 23 others.

The main reason is management confusion. 1997165438+1On October 29th, a fire broke out in the security guard of Yanshan Restaurant in Changsha, killing 40 people and injuring 89 others.

The CPC Central Committee and the State Council have always attached great importance to safety work. In view of the safety accidents in recent years, a series of important instructions and work arrangements have been made, and strict requirements have been put forward for safety management.

Strengthening the safety management of dangerous chemicals is one of the important contents in the work of rectifying and standardizing the market economic order throughout the country. Over the years, with the joint efforts of various departments, the management of hazardous chemicals has achieved good results.

However, with the change of the situation, there are a series of problems to be solved urgently in the current management of hazardous chemicals: First, the phenomenon of unlicensed operation is more common. A considerable number of hazardous chemicals business units are still engaged in hazardous chemicals business without obtaining a hazardous chemicals business license as required.

Second, the operating conditions of enterprises are not up to standard. The conditions of some hazardous chemicals business units can not meet the opening standards stipulated by the state.

Third, employees lack professional knowledge. Some employees in hazardous chemicals business units have not received professional training, their professional quality is low, and they lack the necessary knowledge and preventive measures for hazardous chemicals business.

Fourth, the distribution of business outlets is unreasonable. Some local business outlets are located in downtown areas or residential areas, which is not conducive to fire safety.

Fifth, the management of hazardous chemicals is still not in place. There is insufficient coordination among some local departments, unclear responsibilities of issuers and insufficient supervision and management.

The above problems make the management of hazardous chemicals have major security risks, which seriously threaten people's lives and property safety and environmental protection, and effective measures must be taken to solve them.

8. How to manage daily hazardous chemicals?

First, it is necessary to implement the "one-handed" responsibility system and the "one-vote" veto system for environmental safety work, and set up an environmental safety work leading group with the "top leader" of the enterprise as the team leader, the vice president in charge of environmental protection as the deputy team leader, and the heads of various departments as members, reflecting the importance attached to environmental safety work.

The second is to establish a hierarchical environmental safety management system of company-branch factory-construction section-team, define full-time or * * * personnel of environmental safety management at all levels, define the environmental safety responsibilities of all levels and positions, realize the decomposition of environmental safety work layer by layer, and form a good situation in which all employees of environmental safety management participate. "Without rules, there will be no Fiona Fang". The environmental safety management system is a powerful measure and means to realize the environmental safety of enterprises, and it is also a model for employees to practice environmental safety behavior.

In the construction of environmental safety management system, the following principles should be adhered to: first, it should be combined with relevant national and local environmental laws and regulations; Second, it is necessary to realize the rationality and feasibility of formulating environmental safety behavior standards for employees in combination with the actual production of enterprises and the problems encountered in environmental safety work. For more professional and scarce documents, please visit-search this document and visit the user's home page! Comprehensive. The second is to strengthen the investigation and management of hidden dangers of environmental risk sources and improve the environmental safety and risk resistance of enterprises. In order to improve their environmental safety and ability to resist wind risks, hazardous chemicals production enterprises should first make necessary environmental risk assessment of production devices, identify the existing environmental risk sources, formulate reasonable and feasible preventive and emergency measures against environmental risk sources, establish environmental risk source management files, and focus on the management of major environmental risk sources.

So as to lay a good foundation for effectively and emphatically organizing environmental safety investigation. The investigation and treatment of potential environmental safety hazards is an important magic weapon to create a "zero risk" environment and achieve the goal of "zero accidents" in environmental safety.

The principle of "dynamic, normal, professional, meticulous and responsible for problems" should be adhered to in the investigation of environmental safety hazards, and "three in place" should be adhered to. First, the ideological understanding is in place.

Firmly establish the concept of "hidden danger is accident", and clarify that the purpose of hidden danger investigation and management is to implement responsibilities, eliminate hidden dangers, prevent accidents, and most importantly, eliminate the source of accidents. Second, the investigation is in place.

Constantly refine environmental safety inspection standards, formulate different inspection standards for different periods and different inspection objects, and strictly implement hidden dangers investigation. Third, hidden danger management is in place.

Hidden dangers that can be rectified immediately by classified management shall be determined by the responsible person; If it cannot be rectified immediately, conduct environmental risk analysis and implement environmental risk measures.
