Or soaked in 75% ethanol or 0.1% Benzalkonium Bromide for one to three minutes. If necessary, soak in 0.2% peroxy acetic acid solution or apply and rub with 0.2% peroxy acetic acid tampon and gauze.

10. Corpse of patient: wrap tightly with wet clothing which has been soaked in 0.5% peroxy acetic acid solution and cremate as soon as possible.

11. Transportation tools: for outside and inside surface of vehicles and vessels, spray 0.5% peroxy acetic acid solution or 10,000mg/L effective chlorine or chlorine disinfectant solution on the their surface till they get wet and last for 60 minutes.
