A devastating 6.4 magnitude earthquake rocked Taiwan on Saturday, February 6, killing a total of 116 and injuring many others. All but two of the deaths were caused by a collapse of the 17 story tall Weiguan Junlong (Golden Dragon) tower, the only high rise building to collapse in the city.
As crews have searched the area and initial investigations into the collapse have begun, they have discovered empty tin cans inside structural concrete beams. As crazy as that may sound, the reason those cans were there in the first place might be even crazier. A structural engineer told CNA, a Taiwan news channel, that, prior to 1999, use of cooking oil cans in concrete beams was actually not even illegal and were used to make the beams look bigger without adding much weight, for aesthetic reasons. Cooking oil cans. You read that right. The Golden Dragon tower was built in 1983, so the presence of the cans isn’t technically supposed to be a problem. Rebar was also found bent to 90 degrees, instead of 135 degrees, which increases the risk of the rebar loosening in the event of an earthquake.
However, on Wednesday, February 10, Taiwanese authorities did arrest the developer and two executives of the company that originally built the tower, even though the companies that built the structure are no longer in business. According to CNN, the three people arrested will face charges of professional negligence resulting in death.
The video below, by TomoNews US, gives a pretty good rundown of the factors that caused the collapse.
With cranes being on many construction sites, it’s easy for workers to get complacent. Hundreds or thousands of construction materials can be lifted by cranes throughout the project, but all it takes is one time for a disaster to occur.
Getting your communications right is critical on any construction site. For effective planning and coordination, for efficient management of different teams and for health and safety, having a reliable means of keeping everyone in touch at all times is essential.
The Bureau of Labor Statistics (BLS) recently released the National Census of Fatal Occupational Injuries in 2016. Among all industries, fatal work injuries rose 7% in 2016 (5,190 deaths) over 2015 (4,836 deaths). The fatal injury rate per 100,000 full-time equivalent (FTE) workers also rose from 3.4 to 3.6 year over year.
If you have not submitted your company’s OSHA Form 300A electronically through OSHA’s Injury Tracking Application (ITA) yet, you only have a few days left to do so.
Cranes are a necessary and useful piece of equipment on most construction sites, but extreme caution must be taken when working with them, as any failure could be catastrophic or, at the very least, very costly.
The blowing snow of winter does not bring the construction industry to a halt. If you work in the winter, follow these tips to stay safe and warm.
OSHA has long used the language in the OSH act to find and hold multiple employers accountable for the actions of another on construction job sites. For decades, OSHA would not only cite the employer whose employees were exposed to hazards, but would also cite the employer who was designated the “controlling employer” on-site, which is most often the general contractor.
There is an opportunity to revolutionize the way we protect construction workers from fall hazards while dramatically reducing waste and inefficiency in the construction industry. The Hilmerson Safety Rail System™ was designed and engineered with feedback from industry experts with one goal in mind: Reinvent the guardrail to eliminate inefficiencies, cut costs, send zero waste to landfills, and improve workplace safety.
It has not been a good few months to use portable toilets on a construction job site. In September, a 28 year old man was run over by a dump truck while using a portable toilet on his job site in Louisiana. A couple months later, another accident involving a portable toilet has happened.
The controversial Electronic Injury and Illness Reporting rule from OSHA was supposed to go into effect on December 1, 2017, but OSHA has recently delayed that enforcement to allow those affected to become familiar with the new electronic reporting system.
