How long does the virus that causes COVID-19 survive on surfaces, and how should those surfaces be cleaned and disinfected ?
The COVID-19 virus, SARS-CoV-2, can survive on surfaces for varying lengths of time, depending on factors such as the type of surface, temperature, humidity, and the amount of virus present. The timeline for virus survival on surfaces includes up to 4 hours on copper, up to 24 hours on cardboard, and up to 72 hours on plastic, stainless steel, glass, banknotes, and coins. To effectively clean and disinfect surfaces, it is recommended to follow a two-step process: cleaning the surface with soap or detergent and water, and then disinfecting the surface with an EPA-approved disinfectant. Examples of approved disinfectants include diluted bleach, alcohol solutions with at least 70% alcohol, hydrogen peroxide (3%), and quaternary ammonium compounds. It is important to wear gloves when handling disinfectants, ensure proper ventilation, never mix different cleaning products, and disinfect frequently touched surfaces regularly.

What is the correct way to put on and take off PPE to avoid contamination ?
When putting on and taking off personal protective equipment (PPE), it is crucial to follow the correct steps to avoid contamination. Before donning any PPE, proper hand hygiene should be practiced by washing hands with soap and water for at least 20 seconds or using an alcohol-based hand sanitizer. After putting on a disposable gown or apron, gloves should be put on next, followed by a face shield or goggles, a mask, a hair covering if required, and shoe covers if necessary. When removing PPE, hand hygiene should be performed after each piece is removed, starting with the mask, followed by the face shield or goggles, gloves, gown or apron, and finally performing thorough hand hygiene again. By following these steps, the risk of contamination can be significantly reduced, protecting both the individual and others from potential exposure to hazardous materials or infectious agents.
Can you explain the differences between an internal and external rotor motor ?
Motors are crucial components of various mechanical systems, and understanding their types is essential for selecting the appropriate one for a specific application.
