The most effective way to protect yourself against viruses is by frequently cleaning your hands. You may use an alcohol-based hand sanitizer or wash them with soap and water. The CDC recommends washing before and after work shifts and breaks. Objects which have been handled by coworkers, such as office supplies (staplers, pencils, hole punch, etc.) should be cleaned and disinfected daily.
When installing turf there is a lot of grabbing, touching, sharing tools, etc. Having hand sanitizer at the office, vehicles, and job sites will assist in keeping hands clean.
