The Department of Labor is issuing a long-awaited and controversial rule Thursday aimed at better protecting workers from inhaling silica dust.
The new rule dramatically reduces the allowed exposure limits for workers in a slew of industries, from construction to manufacturing to fracking.
About 2.3 million people in the U. S. are exposed to fine grains of silica on the job; inhaling the dust is one of the oldest known workplace hazards. Silica, which is basically sand, scars the lungs, causing diseases like silicosis and cancer.
Secretary of Labor Tom Perez says the existing rule that limits a worker's exposure to silica dust hasn't been changed since the early 1970s. And even back then, he adds, research showed the exposure limit didn't offer adequate protection.
"We've known for over 40 years that it needed to be strengthened, and it has taken 40 years to strengthen it," says Perez. "Many people who are going to work right now and breathing unacceptable levels of silica dust are in for a brighter future."
He says the current rule for construction sites caps exposure at 250 micrograms of silica per cubic meter of air.
"And the science says we need to be at 50," says Perez. "So that's what the final rule will say." That same updated exposure limit will apply to general industry as well, he adds, which will cut the current exposure limit in half.
Silica can be found in materials like concrete, brick and stone. Busting up those materials sends silica dust into the air. Workers can also get exposed in manufacturing industries that use sand, such as foundries.
Tom Ward, a brick and stone mason in Detroit, is strongly in favor of the new rule. His father died of silicosis after doing sandblasting at his job.
"We watched my dad basically suffocate," Ward recalls, adding that when he first started working, he didn't realize his saws and grinders also exposed him to silica dust.
He now worries about what he breathed in, and says he's troubled whenever he passes a construction site and sees workers in a cloud of dust.
"They have no idea that they're slowly poisoning themselves over their careers," Ward says.
Under the new rule, employers will have from one to five years to put protections in place, depending on the industry.
"We're estimating that once it's fully in effect it will save about 600 lives a year," says David Michaels, the head of the Department of Labor's safety agency, the Occupational Safety and Health Administration (OSHA). The rule is also expected to prevent more than 900 cases of silicosis each year, Michaels says.
Controlling silica dust typically means using vacuums, wetting down surfaces or having workers wear respirators.
"Silica is a killer and employers need to take the necessary steps so that they can reduce exposure," says Perez. "And the good news is that those necessary steps are not going to break the bank. It's real simple stuff. Get a vacuum. Get water. Those are the key elements of pretty simple compliance."
Before issuing this rule, the government held weeks of hearings, took comments from thousands of stakeholders and did all kinds of analyses that took years, says Michaels, who notes that "we have to show that the rule will be economically and technologically feasible for every industry that we cover."
But a lot of industry groups disagree with that assessment and have fought against the new rule.
Brian Turmail, a spokesman for the Associated General Contractors of America, says if a dust-producing part of a construction site has to be cordoned off and put off-limits to all workers except those in protective gear, "you would delay or lengthen the time it takes to complete projects. And certainly the cost of building any type of construction project — because virtually every type of construction project is going to create dust — will go up significantly."
He thinks officials should have focused on better enforcement of the existing exposure limits.
That point is echoed by Neil King, the outside counsel to the American Chemistry Council's Crystalline Silica Panel. "OSHA's own inspectors, when they conduct inspections, have been finding — year after year — that in more than 30 percent of the cases, the existing permissible exposure limit is exceeded," says King.
If industries consistently complied with existing limits, he says, "the number of silicosis cases, which has already fallen by 90 percent, would basically fall to zero or something very close to zero."
Others say that the administration has underestimated what it will cost businesses to comply with the new rule. Amanda Wood, director of employment policy for the National Association of Manufacturers, notes that OSHA says the cost will be hundreds of millions of dollars. "Based on our estimates, we know that the true cost will be more in the billions," Wood says.
She says her organization will consider all of its options in preparing a response, including turning to Congress or the courts for assistance.
DAVID GREENE, HOST:
One of the oldest known workplace hazards is breathing in silica dust. Silica which is basically sand damages the lungs and causes diseases like silicosis and cancer. Over 2 million people in this country get exposed to silica at work. And today, the Department of Labor is issuing a controversial new rule that dramatically reduces the amount of silica workers are allowed to breathe in. NPR's Nell Greenfieldboyce reports.
NELL GREENFIELDBOYCE, BYLINE: Silica is in concrete, brick, rock. When you bust that stuff up, silica dust flies into the air. The danger has long been obvious.
(SOUNDBITE OF FILM, "STOP SILICOSIS")
UNIDENTIFIED MAN: 1935, a wave of fear was sweeping the country. Silicosis was taking its toll from the ranks of American workers. Cause of the disease - dust. Results of the disease - disablement, poverty, death. Cure for the disease - none.
GREENFIELDBOYCE: This movie is called "Stop Silicosis." It was made by the Department of Labor under its first secretary, Frances Perkins. The current secretary of labor, Tom Perez, has her portrait over his desk.
TOM PEREZ: Frances Perkins is the gold standard of all labor secretaries.
GREENFIELDBOYCE: What do you think she would think about this silica regulation?
PEREZ: She'd probably say it's about time.
GREENFIELDBOYCE: He says the existing rule that limits how much silica workers can be exposed to hasn't been changed since the early 1970s, and even back then the science showed it was inadequate.
PEREZ: So we've known for over 40 years that it needed to be strengthened, and it has taken 40 years to strengthen it.
GREENFIELDBOYCE: The biggest impact will be on construction. One worker who's strongly in favor of the new rule is Tom Ward. His father died of silicosis after doing sandblasting at his job.
TOM WARD: We watched my dad basically suffocate.
GREENFIELDBOYCE: Ward is a brick and stonemason in Detroit. When he first started working, he didn't realize his saws and grinders exposed him to silica dust. He worries about what he breathed in, and he's troubled whenever he passes a construction site and sees workers in a cloud of dust.
WARD: They have no idea that they're slowly poisoning themselves over their careers.
GREENFIELDBOYCE: The new limits on silica exposure will affect not just construction but a slew of other industries, from dental labs to fracking.
DAVID MICHAELS: We're estimating that once it's fully in effect, it will save about 600 lives a year.
GREENFIELDBOYCE: David Michaels is the head of OSHA, the Labor Department's safety agency. He says before issuing this rule, the government held weeks of hearings, took comments from thousands of stakeholders and did all kinds of analyses.
MICHAELS: We have to show that the rule will be economically and technologically feasible for every industry that we cover.
GREENFIELDBOYCE: But a lot of industry groups argue that it won't be. Controlling silica dust means using vacuums, wetting down surfaces or having workers wear respirators. Brian Turmail is the spokesman for the Associated General Contractors of America. He says if you've got to cordon off a dusty part of a construction site and only let in workers with protective gear...
BRIAN TURMAIL: You would delay or lengthen the time it takes to complete projects and certainly the cost of building any type of construction project - because virtually every type of construction project's going to create dust - will go up significantly.
GREENFIELDBOYCE: He thinks officials should've just better enforced the existing exposure limits. Amanda Wood is director of labor employment policy for the National Association of Manufacturers. She says the administration says the cost of this new rule will be hundreds of millions of dollars.
AMANDA WOOD: Based on our estimates, we know that the true cost will be more in the billions.
GREENFIELDBOYCE: She says they'll be considering all their options for how to respond, including turning to Congress or the courts.
