Before evacuating the lab in case of earthquake or other emergency, you will:
turn off gas valves and electrical equipment.
clean your desktop and work area thoroughly.
pick up all solids from the floor and sink even if they are not yours.
wash your hands and any other area of skin that has contacted lab equipment or lab benches.
make sure floor area, fume hoods, and sink area are clean.
The correct answer and explanation is :
The correct actions to take before evacuating the lab in case of an earthquake or other emergency would be to:
- Turn off gas valves and electrical equipment: This is crucial to prevent further hazards, such as fires or explosions, after the initial emergency. Unattended gas lines could leak, and electrical equipment could spark or short-circuit, leading to additional risks. Shutting off these systems ensures that they do not contribute to a more hazardous situation.
- Clean your desktop and work area thoroughly: Cleaning your work area helps to prevent the spread of chemicals or biological agents that might be hazardous during an evacuation. It also ensures that nothing is left behind that could become a fire hazard or obstruct evacuation routes.
- Pick up all solids from the floor and sink even if they are not yours: This action helps to clear the area of any objects that could cause injury during the evacuation, especially if the floor becomes slippery or if people need to move quickly. Additionally, picking up items that may be hazardous is important in preventing spills or exposure to harmful substances.
- Wash your hands and any other area of skin that has contacted lab equipment or lab benches: In case of any chemical spills, biological contamination, or exposure to hazardous materials, washing your hands and skin is vital to reduce the risk of poisoning, burns, or infection. This also helps prevent contamination from spreading to other areas.
- Make sure the floor area, fume hoods, and sink area are clean: Ensuring that the floor and equipment areas are clean helps to reduce the risk of contamination or injury during evacuation. It is essential to maintain these areas free from any chemical spills or debris that might become obstacles during an emergency. Additionally, clean fume hoods ensure the proper ventilation and reduce exposure to hazardous fumes.
In conclusion, these actions not only help to ensure safety during the evacuation but also minimize the risk of further harm after the emergency. Properly shutting down equipment, cleaning areas, and ensuring personal hygiene are essential steps in minimizing risks to yourself and others during an emergency in a lab setting.
