In a briefing outside the building on Wednesday afternoon, Infrastructure Development MEC Jacob Mamabolo said his department had commissioned an assessment of various buildings around the city in 2017 for occupational health and safety. The report which was presented on August 27, 2018, had revealed that the Bank of Lisbon building was only 21% compliant with occupational health and safety standards, against the norm of 85%.He warned against speculating about what may have caused the blaze. However, the National Education, Health and Workers Union and the Democratic Nursing Association of South Africa have both said that they reported safety issues in the building since 2014. #JoburgFire today I lost my husband, my best friend, father to my children.
