Two men narrowly avoided being buried by ice chunks falling off a building's roof in northern China.

CCTV footage filmed in Ulanqab in Inner Mongolia on April 3 shows two men calmly standing in front of a building to record the ice chunks falling off its roof.

However, the entire frame was engulfed in a whiteout just in seconds, with only one of the men in a brown jacket managing to run into the house before being completely covered.

After all the ice chunks stopped falling, the man in a red jacket ran into a house on the side while laughing.

It was a close call for the pair, who were lucky to escape unharmed from the unexpected incident.

4月3日，内蒙古乌兰察布，两名男子本想记录积雪从厂房顶部滑落的景象，结果没想到突然发生了“雪崩”。工厂的监控视频显示，房顶落下的积雪速度逐渐加快，男子还在淡定举手机拍摄，下一秒整个监控画面变得白茫茫一片，等画面清晰后，棕色衣服的男子已经跑进屋内，只剩红衣男子一人留在雪中，红衣男子最后也笑着跑进屋内。
