What Could Dust Extraction Cost You?

Dust extraction on a jobsite must be handled carefully, or the mistake could mean steep OSHA penalties.

The Occupational Safety and Health Administration (OSHA) takes airborne and surface-borne dust very seriously because of its severe risks to job site workers and public safety. Every year, more than 2 million construction workers are exposed to materials that contain silica, including concrete and stone.

Prolonged exposure to silica dust – or even short-term exposure in some cases – can cause a condition called silicosis, which compromises respiration. In affected people, scars form deep within the lungs, limiting the breath and increasing the risk of lung infections like tuberculosis. There is no cure for silicosis.

In 2016, OSHA updated the Crystalline Silica Rule, establishing tougher standards for respirable crystalline silica, including an enforcement schedule that’s in effect for construction sites, industrial settings, maritime operations and contractors. The standards are much stricter than those set by OSHA’s original silica rule in the 1970’s.

Is your work site in full compliance with the new rule? Here’s why it should be. 

How to Manage Dust Extraction the Right Way

To handle crystalline silica dust properly, follow all OSHA standards for respirators, exposure limits, engineering controls and other measures that directly affect worker health and safety. Monitor exposure levels and stay within the boundaries of exposure limits: 50 micrograms per cubic meter of air at an 8-hour, time-weighted average.

Use a high-quality HEPA vacuum to filter the air and remove airborne particles created by grinding, drilling, mixing, cutting, blasting and other worksite activities. Plan for both wet and dry activities and ensure all workers are fully trained on precautionary procedures in case an emergency arises.

Pullman Ermator, maker of single-phase HEPA dust extractors, recently conducted a cost analysis on what bags, filters and labor could cost you for dust extraction over a year. The first is your initial cost, where your choices include 150 CFM and smaller plastic dust vacuums that are HEPA-ready or HEPA-included.

Your annual filter costs depend on the type of vacuum you are using. Single-motor dust vacuums with self-pulsing or shaking filter systems need to be replaced periodically. While a HEPA-ready vacuum needs a filter change every two months, HEPA-included dust extractors run for 18 months without a filter change. Figuring in the price for each type of filter bag, plus the annual labor cost of changing two bags per day during a six-day work week for 50 weeks a year, the HEPA-included models come out on top – even though the filter bag price is higher. In the long run, you could end up paying $3,000 more for a plastic dust vacuum. Purchasing any S-line dust extractor may have a higher initial cost, but you still can save thousands of dollars year after year.

Failure to Comply Penalties Go Beyond Basic Cost

OSHA’s enforcement penalties for the Crystalline Silica Rule come with expensive fines. The lowest level serious violation previously cost the violator $7,000 in fines. In the updated standards, the same level violation costs $12,471 per incident and is likely to trigger a deeper investigation by OSHA and other governmental authorities.

After the first incident, it’s the company’s responsibility to manage abatement procedures and prove to OSHA that abatement has taken place. Otherwise, you’ll face a failure-to-abate fine of $12,471 per day beyond the abatement deadline from OSHA.

The biggest penalty comes from either waiting too long to address issues or allowing them to take place repeatedly, which OSHA considers a willful violation. This comes with a staggering $124,709 fine, which can be doubled, tripled or more if you have numerous serious violations across your enterprise.

Putting Worker Safety At Risk

The cost of non-compliance goes much deeper than dollars. Failure to manage crystalline silica dust can destroy the health of your workers. Part of OSHA compliance is providing medical exams at least every three years to workers who wear respirators for more than 30 days at a time. These standards are set for a reason – to prevent workers’ health and lives from being permanently affected by worksite hazards.

Non-compliance can also ruin your company’s reputation in the industry. When competitors, partners and the public get wind of unethical practices, word spreads like wildfire and it can permanently tarnish a company’s image. Just one violation could severely limit the number of jobs your company is awarded in the future.

To keep your worksite risk at an absolute minimum, contact your Runyon sales rep to examine the site and put protective measures in place. It’s a proactive step towards staying well within OSHA boundaries and making sure dust doesn’t cost you money and lives.

Guide to Cleaning Up Oil Spills on Concrete

Aside from daily maintenance, there are times when unexpected spills happen. Left untreated, they can leave behind discoloration and stain your otherwise beautiful floor. In the case of our warehouse, we had hydraulic fluid leak onto our floor as we were unloading a large piece of equipment. Luckily, we were quick to remediate the situation and document (with pictures) the entire process.

We were unloading a power trowel off a pallet when we noticed a bit of fluid was leaking. Upon further investigation, it was identified as hydraulic fluid and was dripping onto the floor. Our team was extremely responsive in both identifying and stopping the leak.

We removed as much of the fluid as possible using clean dry cloths. It’s important to remember that polished concrete is not a coating and will absorb the oil, which is why it’s important to get it up as soon as possible. This is also why a dry cloth is the best method to remove as much fluid as you can. The use of mops, auto scrubbers, etc. at this point will only help the fluid penetrate deeper into the concrete.

Once we removed as much fluid from the methods listed above, it was time to use a product specific to oil and stain removal. We chose to use Prosoco Oil & Grease Stain Remover, as this was available in our warehouse and does the job well.

The instructions call for the glue like substance to be poured onto the stain and left untouched to dry, which in our case was overnight. The product pulls the contaminants out of the substrate, capturing them in its highly absorbent blend of batter-thick surfactants, solvents and powders.  I attempted to take pictures throughout our workday to track this process.

Once dry, we simply swept up the powdered remains and auto scrubbed the floor as a part of our daily maintenance routine. In all, I believe the biggest contributor to the successful removal of oil and grease stains is to address them as soon as possible. The stain definitely faded in color, but will probably require another treatment or further remediation down the road. Had the concrete not been polished, we would have expected the stain to dissipate completely. Coming from a background in concrete coatings and coating removal, I’ve been curious to compare and contrast differences in polished concrete and coatings. This was a great case study!
