The National Institute for Occupational Safety and Health (NIOSH) has recently published a new study that finds a low cost solution to harmful silica dust. Inhaling silica dust, which is commonly found in fiber-cement siding, can lead to a lung disease called silicosis, which is deadly. While silicosis is preventable now, it's estimated that 100 people still die from it each year.
The study shows that by attaching a regular shop vaccuum to a dust-collecting circular saw can reduce exposure to the hazardous dust produced when cutting fiber-cement siding. NIOSH lead researcher on the project, Chaolong Qi, Ph.D. said that by "Implementing this intervention, with a tool these workers are already likely to have available to them, can protect workers from a potentially deadly disease." With just the use of a common shop vacuum, the study concluded that the level of silica-containing dust was held well below the exposure limit to crystalline silica that NIOSH recommends, which is 0.05 mg/m3.
Other recommendations that NIOSH makes to reduce silica dust exposure:
- Shop vacuum should have an air flow rate of 30 CFM and a hose connected to the saw
- The hose should be 1.25 inches or larger in diameter
- Use a high efficiency disposable filter bag
- Use an intelligent vacuum switch, which turns the vacuum on and off as needed to reduce uncontrolled dust release. Aftermarket devices can be purchased if yours does not currently have one
- The circular saw you should use should have a built in dust collection container that can easily be connected to a shop vacuum
- The saw blade tip should be made of poly-crystalline diamond (PCD), which are designed to cut fiber-cement siding
This gives me more confidence in OSHA that they are looking for practical, everyday fixes to common problems that don't take a lot of money or training to implement. I look forward to more common sense solutions in the future.
[guest post] It’s a morbid statistic, but the construction industry experiences more workplace deaths than any other. With so many potential hazards, heavy-duty machinery, and power tools, it’s perhaps not surprising that serious accidents are relatively commonplace.
Even though we’re over a year into the COVID-19 pandemic, the virus is still threatening the health of construction’s workers and taking a toll on project timelines. It’s likely that your company has already determined the best course of action to help mitigate the risk of spreading the virus on your jobsites, but it’s never too late to learn from another contractor.
It’s been a little over a year since the coronavirus pandemic sent the entire world into a period of uncertainty, heartache, and panic. The construction industry itself has undertaken many different challenges, above and beyond keeping their people safe on the jobsite, many of which no one could have expected.
“You make a better door than a window!” is what I imagine loader operators constantly yell at the bucket in front of them (or maybe I’m just projecting based on my experience of having the habit of sitting right in front of the TV as a kid). Either way, operators may not be yelling that in the future, as equipment manufacturer, Doosan, has introduced what they claim is an industry first “transparent” bucket.
Reducing dust when cutting tile is important for many reasons (including safety and cleanliness), but wet tile saws can be a pain to use, with the slurry created spraying all around the work station and cold weather making the saw much more difficult to use outside. iQ Power Tools has a solution for that: the world’s first 7” portable dry table saw with integrated dust control.
In the construction industry, falls from height are continuously the leading cause of jobsite injuries, fatalities, and, as a result, OSHA citations. From May 3-May 7, OSHA invites construction employers and stakeholders to take part in their 8th annual National Safety Stand Down to Prevent Falls in Construction.
On Tuesday morning, February 23, the Syracuse Fire Department responded to a call about a collapsed crane on a construction site near the university. Thankfully, no injuries were reported.
It seems a little odd to be talking about air-conditioning when much of the United States hit some incredibly low temperatures in recent days, but a product that I learned about recently is just too exciting to ignore. Announced at CES 2021, a research company has unveiled an air-conditioned hard hat (ACHH) that can reduce the ambient temperature up to 22 degrees Fahrenheit!
2020 was a challenging year in many respects, but none greater than from a safety standpoint. The coronavirus pandemic placed the notion of “people over profits” under the microscope, while also balancing the needs of their employees to continue to make an income under difficult circumstances. While the pandemic was a large part of the construction safety conversation last year, there were several other developments to take note of for your projects in the future.
Last summer, Hilti announced that they had developed their first exoskeleton designed for construction tradespeople in a partnership with Ottobuck, a prosthetics, orthotics, and exoskeleton provider. Earlier this month, Hilti officially released the exoskeleton, announced more details, and published its retail price on their website.
