Crystalline silica is one of the most common elements on the planet, just behind oxygen. About 2.3 million workers are exposed to it in their workplace. It’s about 100 times smaller than sand and can be found on construction sites in building materials such as concrete, block, stone, sand, and mortar.
Crystalline silica is an abundant natural material found in soil, stone and sand. It is also present in many construction materials such as brick, mortar and concrete. It becomes respirable when any of the afore-mentioned materials are cut or broken down into fine particles.
Crystalline silica is one of the most common minerals found worldwide in the earth’s crust. It is frequently used in many industrial processes such as mining, quarrying and stone-cutting. Breathing air contaminated with crystalline silica particles can cause serious respiratory and lung diseases.
At the start of September, the number of open jobs exceeded the number of active jobseekers for the 17th consecutive month—a record for the United States economy.
OSHA estimates some two million construction employees are exposed to respirable crystalline silica in more than 600,000 workplaces across the country. To comply, companies need to follow multiple steps that aren’t always as easy as they might seem.
When loud noises cannot be reduced or eliminated through engineering controls, workers who are exposed to them must use hearing protection devices (HPDs) to conserve their hearing. This notion is not new, nor is the concept that HPDs require fit-testing to be effective.
An unplanned event that did not result in injury, illness, or damage, but had the potential to do so — are common but generally underreported. Knowledge is power, and information provided by near-misses is a tool to evaluate and improve safety.
The 2018 print edition of NFPA 70E Standard for Electrical Safety in the Workplace® is 104 pages. Updated every three years by the 70E technical committee, this comprehensive standard covers the latest information about the effects of shock, arc flash, arc blast, dc hazards, and developments in electrical design, PPE.
We’re coming up on an anniversary: in 1970 Congress passed and President Richard Nixon signed into the law the Occupational Safety and Health Act, creating the Occupational Safety and Health Administration, OSHA.
