TOXIC FUMES ALERT SHUTS ROYAL MILE.
Firefighters wore protective suits to enter the Whiteford House hostel in Canongate after two staff members inhaled toxic fumes.
A police spokesman said: "It would appear bleach poured down a drain reacted with something already there, releasing the fumes."
It was revealed a cleaner poured bleach down to get rid of a strange smell.
The two women workers were checked over by ambulance staff but did not need medical treatment.
Health and safety officers shut off the lower section of the Royal Mile from 11am to 1pm as they worked to establish the source of the fumes.
None of the elderly residents at the home was evacuated.
