No risk scenario. No testing warranted. As stated by biology the virus is rendered inactive the moment it comes in contact with the environment. No scope of transmission.
No risk
Not necessarily, but for a peace of mind
Yes
virus is inactivated and degraded in air, not instantly, but within seconds after it leaves a host cell. it is either inactivated by dryness or uv ray. not much scientific proving have been done here. Drying infected blood and testing for its infectious level does not prove anything much. it is impossible to throw a virus in the air and watch it degrade.
