Hand sanitizers are not intended to replace handwashing in food production and retail settings. Instead, hand sanitizers may be used in addition to or in combination with proper handwashing.

CDC recommends that everyone wash their hands with plain soap and water. Alcohol-based hand sanitizers may be used if plain soap and water are not available. As an interim measure, we understand some food establishments have set up quaternary ammonium hand-dip stations and sprays at 200 ppm concentration.

These products are intended for use on surfaces, and as such, may not be formulated for use on skin. FDA is aware of adverse event reports from consumers using such products as a replacement for hand sanitizers and advises against using these products as replacements for hand sanitizers.

However, this temperature is far outside the limits of human comfort and could damage some building materials.

What does a N95 respirator protect you from during the COVID-19 pandemic?

Can the coronavirus survive on surfaces?

It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).

The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.

• Used in this way, CDC has recommended cloth face coverings to slow the spread of the virus that causes COVID-19. Wearing them may help people who unknowingly have the virus from spreading it to others.
• Workers can wear a cloth face covering if the employer has determined that a respirator or a disposable facemask is NOT required based on the workplace hazard assessment.
