Crystalline silica is found in many construction materials, including concrete, stone, and brick masonry. The inhalation of silica dust is thought to contribute to the formation of many health hazards, including lung cancer, silicosis, COPD, and kidney disease. Estimates have shown that silica exposure kills 600 American workers and results in 900 new cases of silicosis each year, OSHA has been working on tightening its rules regarding the exposure to this type of dust for several years and has finally issued a new “final rule,” it’s first update on the rule since 1971.
The updated rule, which will go into effect for the construction industry on June 23, 2017, specifies the following:
Exposure limits reduced
Workers are now limited to being exposed to only 50 micrograms per cubic meter of air averaged over an 8 hour shift. This is 5 times less than the previous allowable limit of 250 micrograms. 1 microgram is equivalent to one millionth of a gram.
Requirement of engineering controls and/or PPE
Water and ventilation practices to limit worker exposure are required when exposures exceed the allowable limit. When the engineering practices are not enough to keep dust levels under the limit, the employer is then required to provide respiratory protection for workers. The employer is also responsible for training employees and providing medical exams for highly exposed workers
Table of specified controls
Clearly, not many people understand what 50 micrograms of dust looks like, nor should they. Because of that, OSHA has included a table of specified controls in order to clear up uncertainties for construction employers. For example, when workers are using a stationary masonry saw, they should be using a saw that is equipped with a water delivery system that continuously feeds water to the blade. In doing so, they are not required to wear respiratory protection. Handheld power saws should also be used with a water delivery system, but require a respiratory protection with a factor of APF 10 when outdoors and exposed for greater than 4 hours and all the time, when indoors.

Many construction organizations are unhappy with the new rule, including all of the members of the Construction Industry Safety Coalition (CISC). According to the group, which includes the Associated Builders and Contractors, Associated General Contractors, National Association of Home Building, among many others, OSHA has “not met its burden of demonstrating that the proposal is technologically and economically feasible.“ Though the group ultimately has the desire to protect the industry’s employees, it wants to make sure new rulings don’t put an undue pressure on employers that would not allow them to live up to their end of the bargain.
“Instead of crafting a new standard that the construction industry can comply with, administration officials have instead opted to set a new standard that is well beyond the capabilities of current air filtration and dust removal technologies,” said Stephen E. Sandherr, the CEO of the Associated General Contractors of America, in a press release. “Our concern is that this new rule will do little to improve workplace health and safety, which is why we will continue our review of the new measure, consult with our members and decide on a future course of action that will best serve the health and safety of millions of construction workers across the country.”
In a document released in March of 2013, the CISC not only deemed the new rule technologically and economically infeasible, but also unnecessary. According to the Center of Disease Control, silica related deaths have dropped by 93 percent from 1968 to 2007. The organization also stated that it believes OSHA’s estimate for how much the new rule would cost the industry was very far from reality. While OSHA expects the program to cost $511 million for companies to comply, the CISC estimates total costs to be almost $5 BILLION.
No matter which side you fall on, one thing’s for sure. These two sides need to come to some sort of compromise to make this program successful.
In January of 2017, OSHA released a final rule which greatly reduced the allowable exposure to beryllium, a mineral that can cause deadly lung disease. While not as commonly encountered in the construction industry as other substances that cause terrible lung diseases, like crystalline silica and asbestos, beryllium is linked to a disease called chronic beryllium disease, which kills around 100 people each year. It’s commonly found in coal slag, which is used for sandblasting. According to the New York Times, OSHA estimates that 11,500 construction workers would be affected by OSHA’s reduced exposure limit.
As recently highlighted by several multi-story building fires, contractors should always be prepared in the event a fire starts on a job site. There have been dozens multi-story building fires in the past few years and many were started when the building was topped out. In most cases, the project was completely destroyed, leaving developers and owners to deal with years of delays from insurance claims. A massive five-alarm fire at an Oakland construction site is one of the more recent examples.
In a year that OSHA can’t seem to enforce any new rules, it appears to have found a way to remove a rule from its books. As announced last week, OSHA has removed monorail hoists from Subpart CC – Cranes and Derricks in Construction. Employers are still required to follow other OSHA regulations regarding the hoists, but this rule should help clear up some inconsistencies.
For many construction superintendents and project managers across the world, tablets are becoming one of the most important tools on the job site. They’re great for looking at plans, taking pictures, making notes, and running your favorite construction apps. Carrying a tablet does take up at least one of your hands, however, so it can be a hindrance if you need to help a co-worker lift material or climb a ladder.
High demand battery packs have allowed many construction workers ditch the cords on jobsites throughout the country, by providing more power and longer runtime. As with any battery packs, it’s important to follow safety warnings, but with a higher capacity can sometimes mean greater consequences when those warnings are not followed.
Since the beginning of the year, OSHA has had a pretty hard time enforcing any of its new rules due to delays. The silica dust exposure rule was delayed 90 to September 23, the crane certification rule is facing yet another possible delay, and now the electronic injury reporting rule is facing another delay.
Just before 11 am on Monday morning, 6/26, firefighters were called to an under-construction residential building in Queens, New York after concrete scaffolding and formwork collapsed during a pour.
Two construction workers in Sarasota, Florida were recently trapped 15 stories in the air after one of the lines on their suspended scaffolding snapped. One of the two men was able to be pulled to safety by some co-workers on site, but the second was stuck on the scaffold for an hour before the fire department could rescue him.
According to OSHA, more than 40 percent of all heat-related worker deaths occur in the construction industry. Many more workers also become ill from extreme heat and humidity. With summer now in full effect, it’s time to re-evaluate your personal steps for keeping safe in the heat and how your company is going to help their employees stay safe.
Every now and then a new product comes along and you ask yourself, “why didn’t I think of that?!” The OVAL Fire Extinguisher is just that product. Architecture and interior design have been moving towards cleaner lines in their spaces. Foregone are the days of bulky protruding water fountains (bubblers for my northern friends) and fire extinguisher cabinets. Interior designers are looking for cleaner and sleeker interior spaces but the 10lb fire extinguishers and cabinets have not changed for quite some time. OVAL is about to change all that.
