ST. LOUIS — A construction safety expert says incidents like what happened in downtown St. Louis Monday, are actually on the rise.

Two construction workers died in an accident on 15th and Washington Avenue. A third worker was injured.

"We’re spending more on fall protection equipment, and overall we’re safer workplaces but the number of fatalities due to falls continues to rise," said Thom Kramer, an expert with the American Society of Safety Professionals.

Kramer said this isn't something companies can just throw money at.

"The number of fall fatalities has increased from 561 in 1995 to 849 in 2016, even though the number of dollars spent on fall protection has gone up 160 percent since then," he said.

Kramer said training expectations have to improve because the 849 killed in 2016, nationwide, would be considered a crisis in any other field.

"But when you look at 849 people, that’s several jumbo jets that would fall out of the sky every year, and in the United States we wouldn’t allow for that to happen," said Kramer.

In the St. Louis region, 5 On Your side went through numerous OSHA and labor reports and counted 18 fall-related incidents resulting in nine deaths, since 2014.

In Missouri, falls make up one out of every 15 work-related accidents.

Thom said OSHA will now work to recreate the scene, inside the old International Shoe building.

"Was there an anchorage-independent of the platform they were suspended from because that’s often one requirement that’s often in the OSHA requirements is that you have to have an anchorage that’s independent from the platform?" asks Kramer.

He said pinpointing the exact cause of the accident is critical so that this growing trend finally reverses.

"They’re not that uncommon," he said.

OSHA will continue to investigate what happened. Kramer said if the federal government finds the contractor, Gencorp, responsible, they could face up to hundreds of thousands of dollars worth of fines.
