Los desperdicios del laboratorio se descartan en:
a. fregadero
b. envase correspondiente
c. zafacón
d. en la campana extractora de gases
The correct answer and explanation is:
The correct answer is b. envase correspondiente.
Explanation:
In a laboratory setting, the proper disposal of waste is crucial for maintaining safety, health standards, and environmental protection. Laboratory wastes can vary from biological materials, chemicals, to hazardous substances. Therefore, it is necessary to discard each type of waste in the correct container, or “envase correspondiente.”
- Fregadero (sink): Discarding waste in the sink is generally not allowed, especially for chemicals or hazardous materials, as they can contaminate the water system and harm the environment. Some non-hazardous, water-soluble substances may be disposed of down the drain, but it is important to confirm the type of waste with the laboratory guidelines.
- Envase correspondiente (correct container): This is the most suitable method for disposing of laboratory waste. Each type of waste should be discarded in a specific container designed for its material. For example, biohazardous waste, such as used petri dishes, gloves, and tissue cultures, should be disposed of in biohazard bags or containers. Chemical waste, such as solvents or reagents, should be placed in designated chemical waste containers. Sharps, such as needles and broken glass, should be discarded in puncture-resistant sharps containers. This separation prevents contamination and allows for proper waste treatment and disposal later.
- Zafacón (trash bin): Discarding laboratory waste in a regular trash bin is not recommended. It may lead to contamination, exposure to hazardous materials, and issues with disposal companies that are not equipped to handle laboratory-specific waste.
- Campana extractora de gases (fume hood): A fume hood is used for handling volatile chemicals or substances that release harmful vapors, but it is not a place for waste disposal. The fume hood’s primary purpose is to protect individuals from inhaling toxic fumes or gases during experiments, not for discarding waste.
In summary, the correct and safest way to discard laboratory waste is by following specific waste disposal protocols, including placing the waste in the correct container for proper handling and treatment.
