EXPLORATION IS VALUABLE,
BUT SAFETY IS
EVEN MORE CRUCIAL
COMMON CHEMICAL
LABORATORY EMERGENCY
RESPONSE DRILL
The chemistry laboratory is the base for students to explore the mysteries of the world and an essential place for conducting scientific research. In laboratory activities, various chemical reagents and types of equipment are typically used. During these operations, there is a potential for emergencies due to improper handling. To ensure preparedness for these potential risks and enable all students to explore the ocean of knowledge safely, the school conducted an emergency response drill for common chemical laboratory accidents in the chemistry laboratory on October 31st.
At the beginning of the drill, Director Liang from Huamei Foreign Language School's Safety Office explained the purpose and significance of the drill and officially declared the start of the exercise.
The drill covered two accident scenarios:
Reagents in the chemistry laboratory that may cause burns include acids, bases, and strong oxidants. In the case of a student accidentally splashing sodium hydroxide solution on their hands while measuring a certain amount, when this emergency situation is recognized, the student should immediately wipe off any chemical reagent on the skin with a clean cloth or paper, then rinse the affected area with a large quantity of running water for at least 15 minutes. Afterward, neutralize with a 3% boric acid solution and apply a wet dressing. Simultaneously, inform the school nurse for further diagnosis and observation, and in severe cases, arrange for immediate professional medical treatment at a hospital.
Many experiments in the chemistry laboratory involve heating. In an experiment to produce oxygen by heating potassium permanganate, a student's arm came into contact with a test tube being heated due to improper handling. In case of a burn, the symptoms should be observed first. If there is redness and swelling on the surface of the skin, with the appearance of blisters, urgently cool the affected area with cold water. Before the blisters burst, you can gently apply iodine tincture to the burn, followed by applying burn ointment to the affected area. Simultaneously, inform the school nurse for further diagnosis and observation, and in the case of unexpected developments, arrange for immediate professional medical treatment at a hospital.
After the drill, the students received additional safety education in the chemistry laboratory, emphasizing the importance of engraving safety awareness in their hearts and leading them to constantly remember, "Exploration is valuable, but safety is of higher value!"
