巴西圣保罗州将严查公共场馆
The governor of Brazil's most populous state, Sao Paulo, has ordered tighter inspections of all venues, including nightclubs, cinemas and theatres.
巴西人口最稠密的圣保罗州州长下令对所有场馆进行严格检查，包括夜总会、电影院和剧院。
The measure follows a fire that killed 235 people at a nightclub in the southern city of Santa Maria on Sunday.
Meanwhile, more than 20 survivors who were thought to have escaped unharmed have been admitted to hospital.
Doctors say they are suffering from chemical pneumonia（肺炎） -- a respiratory（呼吸的） disease caused by inhaling toxic fumes.
There are now 141 patients in various hospitals, of which more than 70 are in critical condition, authorities say.
The deadliest fire in Brazil for half a century has led to widespread calls for tighter legislation and controls for venues.
In Sao Paulo state, firefighters were due to launch a so-called Maximum Prevention operation on Wednesday evening.
The action was announced by the state's governor, Geraldo Alckmin, who said it would involve around 300 teams of firefighters.
The sweep is to target nightclubs with an area of more than 1,000 sq metres at first, but should gradually be broadened to all of Sao Paulo's night venues, such as cinemas, restaurants and theatres.
Meanwhile, the mayor of Sao Paulo city, Fernando Haddad, has announced he intends to make available online the licensing status of all the state capital's nightclubs.
