When he was a kid, Tom Ward thought his dad was Superman, especially because he worked with his hands. When I sat down with Tom a few weeks ago, he talked about how heroic and invincible his father seemed, about his athleticism and his work ethic. But years of working as a sandblaster had taken their toll. They turned out to be this Superman’s kryptonite.

When he was just 34 years old, Tom’s father was diagnosed with silicosis, a progressive, incurable disease afflicting workers who drill, cut, crush or grind materials like concrete and stone. The disease suffocated him, and he literally worked until he dropped.

Decades later, Tom still gets choked up talking about the day his dad fell to the floor and cried, saying he just couldn’t work anymore. “It took about 5 years to kill him,” Tom says, “and we got to watch.” And it wasn’t just a personal tragedy for Tom, his mother and his sisters; it was a financial crisis, too. They lost everything.

Inspired by his dad’s memory, today Tom works as a masonry trainer for the Bricklayers and Allied Craftworkers in Michigan. He’s teaching many of the safety measures that could have saved his father’s life. And he believes we need a better, updated safety standard that protects people who work around silica dust.

Final silica rule released

So on behalf of Tom and his family – and the 2.3 million hardworking people exposed to silica in their workplaces – that’s exactly what we’re doing. Today, Tom joined me as the Labor Department’s Occupational Safety and Health Administration announced a final silica rule that will save more than 600 lives a year and protect the health of thousands of others.

This step is a long time coming. Awareness of the dangers of inhaling dust is almost as old as civilization itself – it goes back to stone-cutting in ancient Greece and Rome. And we’ve known how to prevent silicosis for 80 years since my predecessor, Labor Secretary Frances Perkins, convened a panel of experts to study this issue in the mid-1930s. Throughout recent years, the body of scientific knowledge has expanded – and we know now that breathing in these tiny dust particles can cause lung cancer, emphysema, kidney disease and other diseases. We’ve had a silica standard since the early 1970s, but the overwhelming evidence is that it’s no longer up to the task – in fact, it was out of date from the moment it went into effect.

Now finally, we’re mustering the will to do what needs to be done. At long last, we’re rising to the challenge and taking the bold action this problem demands.

Half the current limit

The new rule will substantially reduce the permissible exposure limit, setting it at 50 micrograms per cubic meter of air – that’s half the current limit for general industry and five times more stringent than the current exposure limit forconstruction. In most cases, this can be achieved using common-sense controls – like wetting down the dust or improving ventilation – to limit exposure. As Tom Ward says: “Turn the water on, turn the vac on.” In fact, some of the necessary equipment can be bought at a well-stocked hardware store.

The rule provides flexibility to employers, giving them room for creativity and options for different ways to achieve compliance. We were very careful to make sure this wasn’t a one-size-fits-all approach.

We also engaged businesses and other stakeholders throughout the process, soliciting their input and incorporating their recommendations. There was a robust comment period, as well as 14 days of public hearings. The final rule contains many changes and improvements from the proposal that we issued in September 2013. Every step of the way, we approached this rulemaking with a keen ear and an open mind. We’ve built a big table and invited everyone to pull up a chair. OSHA also will be all in when it comes to providing technical expertise and compliance assistance to employers.

"The right side of history"

As always when we take action to raise labor standards, we can expect to hear from plenty of “calamity howlers” – people who will hyperbolically claim that a stronger silica standard will devastate industry and kill jobs. But these kinds of claims never are borne out. The sky-is-falling crowd never finds itself on the right side of history. We can’t be sucked into a false choice between occupational safety on the one hand and a sound bottom line on the other hand. Responsible employers tell me all the time that the two go hand-in-hand.

The cost of doing nothing on silica is unacceptably high. It comes in the form of a slow and painful death for workers like Tom Ward’s father. That’s why we’ve worked so hard and so thoroughly to complete this rule. The tough men and women who work with steel, brick and stone – who build our homes, operate our foundries and maintain our roads – deserve nothing less than the best possible protection. Today, we protect their right – one of our most basic rights of all – to come home safe and sound after a hard day’s work.
