Safety awareness
China has at least 210 million primary and secondary school students, with another 22 million enrolled at kindergartens, show official figures.
According to a 2007 joint study by the ministries of education and public security, roughly 16,000 children die in accidents and "abnormal circumstances" every year. The final report states about 80 percent of these deaths are "preventable".
This year has been a particularly bad one for education authorities. In spring, officials were forced to beef up security at schools nationwide following a string of random attacks that left 18 children and two adults dead and another 80 people injured.
Armed guards were placed at school gates in densely populated metropolises like Beijing to remote desert towns like Kangbashi in the Inner Mongolia autonomous region.
Yet, the efforts to prevent further violence may have overshadowed the existing loopholes in safety inspections, especially in impoverished areas, such as Aksu, an agricultural city 1,050 km southwest of the regional capital, Urumqi.
Another study by the Ministry of Education in 2005 found that 60 percent of teachers received less than 10 hours of safety training per semester. Officials were unable to provide an updated figure when contacted by China Daily.
This lack of awareness, coupled with inadequate safety measures, is a key factor in school stampedes, said Zhang Wen, deputy director of legal affairs for the ministry's policies and regulations office.
Following a stampede at a high school in Hunan province that killed eight and injured 26 others in December 2009, the Ministry of Education ordered all schools to check the quality of stairs, handrails and stairwell lighting, as well as to replace any damaged or badly installed equipment.
The ministry released a similar statement on Tuesday, when they encouraged "better management of daily student assemblies" and "swift organization of all-out safety checks".
"These incidents are avoidable if people stick to our documents and requirements," an unidentified ministry spokesman was quoted as saying by the People's Daily. "There isn't any room for bureaucracy and formality when it comes to school safety."
Education bureaus in several cities have urged schools to assign teachers to lead groups of students up and down stairs before and after classes and during scheduled breaks.
The majority of schools in Zhengzhou, capital of China's most populous province, Henan, now has teachers managing the traffic flow on every floor.
In Yantai, a coastal city in Shandong province, authorities have ordered all districts and counties to carry out immediate safety checks and to refine evacuation plans.
However, security experts with companies drafted in to protect children following the attacks in spring say that most of schools still need to invest in better overall safety training for teachers and students.
"I have talked to teachers and students and asked them how they should leave the site when an accident happens. They all give me different answers and none of them are correct," said Hao Peng, general manager of CCG Security's branch in Xi'an, capital of Shaanxi province.
"Schools are more aware of safety after (a tragedy)," said Hao, whose firm has contracts with 56 city schools across central and western parts of China.
Cheng Guanyao at CCG Security's Shanghai office added that many schools have already canceled contracts "as they think it's a waste of money now it's not dangerous any more".
