【Weekly Topic】Production Technology: What are the common accidents that occur during high summer temperatures? 2011.07.31~08.07

Compared to normal times, the high temperatures in summer make it easier for safety incidents such as fires and explosions to occur. Reason: First, high temperatures can accelerate the aging of electrical wiring, leading to electrical fire accidents. Second, some chemical products are highly flammable and explosive, and the high temperatures in summer increase the risk of explosions. Therefore, in hot weather, the slightest carelessness can very likely lead to a fire, causing huge losses to the factory. Therefore, as measures to prevent accidents in high-temperature summer conditions: First, inspect all electrical circuits and replace those that are showing signs of aging promptly. Second, in workshops where explosive chemicals are produced, effective ventilation is essential. Finally, strengthen safety training for operators and raise the level of prevention to ensure a safe and stable summer.

1. Personnel safety: Heat stroke is a common risk in outdoor work； 2. Fires: Fires are likely to occur in hot and dry environments, especially when waste is discarded in areas near welding operations. Our factory suffered a fire a few days ago due to this issue. 3. High circuit load or aging can lead to fires easily ； 4. Flammable and explosive items are prone to accidents. To prevent accidents, it is most important for everyone to have a safety awareness and to follow the procedures. Do not harm others, and do not let others harm you!

During the hot summer months, heat exchangers generally do not perform well in terms of cooling efficiency, and mechanical equipment is prone to shutting down when under high load； Additionally, the high electricity demand in summer can cause fluctuations in the power grid, leading to widespread shutdowns.

1. If the temperature of the pump is too high, it is prone to tripping, resulting in an increased failure rate. 2. Over-temperature and over-pressure conditions increase the difficulty of controlling parameters such as temperature and pressure. 3. High circulating water temperature reduces the cooling effect. 4. High failure rates for electrical and instrumentation equipment. 5. Workers who work outdoors for long periods of time can suffer from heatstroke.

My opinion: Incident 1: Personnel 1. In hot weather, people working under high temperatures are prone to heatstroke. Common practice: Improve working conditions ； Prepare the medication ； Cooling drinks, etc. 2. Due to the hot weather, people wear little clothing while working, or even work without shirts, which makes them more susceptible to coming into contact with chemicals and suffering burns or corrosion from such substances. 3. Hot weather makes people prone to fatigue, increasing the likelihood of human errors in production. Accident 2: Solvents 1. Solvents become more volatile in hot weather, and they pose a risk when they reach their explosive limits. Procedure: Cool down and maintain good ventilation. 2. For expandable liquid solvents, pay attention to proper storage and release excess gas accordingly. 3. Solvent evaporation increases the risk of poisoning. Incident 3: Electrical equipment 1. Accelerated aging of electrical equipment due to high temperatures can lead to fires. Check regularly. 2. Some devices suffer from poor cooling effects due to high temperatures, which can lead to sudden failure and other subsequent hazards. Well, that’s basically all I understand. The key is prevention – more training and more inspections are what matter

1. Major heat protection safety issues for outdoor workers. 2. Underground pipelines should be checked for the presence of flammable gases to prevent explosions. 3. Pay attention to equipment issues. Prevent overheating. 4. Equipment containing liquid materials, to prevent vaporization. 5. Electrical equipment subjected to accelerated high-temperature aging may cause fires. Check regularly. 6. Some devices suffer from poor cooling effects due to high temperatures, which can lead to sudden failure and other subsequent hazards. 7. Strictly control the process parameters to prevent temperature increases.

1. Be careful to prevent heatstroke and stay cool. Workers who are engaged in outdoor work or work in high temperatures should be provided with the necessary heat protection facilities and common heat-relief medications. 2. Pay attention to on-site management and implement disaster prevention measures. Given the frequent occurrence of thunderstorms and typhoons in summer, it is necessary to take proper measures on site for typhoon prevention, flood control, and lightning protection. 3. High circulating water temperature reduces the cooling effect; therefore, it is necessary to strengthen the maintenance of operating equipment to prevent overheating and equipment damage. 4. Strictly control process parameters to prevent the equipment from overheating or overpressuring.

Heatstroke among personnel, explosions of flammable and explosive materials, fires, electric shocks and sparks caused by exposure and aging of electrical circuits, as well as damage to equipment such as motors due to high temperatures. Measures: 1. Inspect all types of wiring; replace them promptly if any signs of aging are detected. 2. For explosive chemicals, implement effective monitoring along with adequate ventilation systems. 3. Strengthen safety training for operators. 4. Control process parameters to prevent equipment from overheating or overpressuring

During the hot summer months, the following accidents are likely to occur: 1. Due to the high temperatures, it is easy for people to suffer from heatstroke； 2. Prone to fires, explosions, and leaks leading to poisoning incidents ； 3. Since summer is a peak period for electricity consumption, aging electrical wiring can easily lead to short circuits and fires ； 4. Power outages occur due to tripping caused by lightning or excessive load. Countermeasures: 1. During hot seasons, take measures to prevent heat stress and avoid outdoor work during the hottest periods ； 2. Carry out proper inspection and maintenance of equipment, strengthen daily inspections, and promptly identify and address potential hazards ； 3. Strengthen the inspection of electrical equipment, replace aged wiring in a timely manner, identify points with poor contact, and carry out repairs and maintenance promptly ； 4. Take appropriate measures to prevent lightning strikes during the summer, formulate emergency plans, and reduce losses caused by power outages.

1. Worker safety: Heatstroke is a risk in outdoor work. 2. Fires: Fires can occur easily in hot and dry environments. 3. High electrical load or aging wiring can lead to fires. 4. Flammable and explosive materials can cause accidents. 5 Trips caused by lightning or excessive load, resulting in power outages. 6 High circulating water temperature reduces cooling efficiency; it is necessary to strengthen the maintenance of operating equipment to prevent overheating and equipment damage. To avoid accidents, it is most important that each of us has a safety awareness and follows the procedures in place. Do not harm others, and do not let others harm you!
