Silica dust is threatening worker's health
By Jessica Krippendorf, Correspondent Journal of Commerce
A massive threat to worker safety is looming before the construction industry. Silica dust, which has been called the new asbestos, is starting to be recognized for taking its toll on worker's health.
WorkSafeBC has recently launched another awareness campaign focused on enforcing jobsite specifications around the control of airborne chemical contaminates, including silica dust.
Al Johnson, regional director for WorkSafeBC said the health and safety authority has increased its focus on occupational diseases. Statistics indicate that while the number of traumatic worksite fatalities has dropped, fatalities due to occupational disease are on the rise.
“Typically, as people are exposed to chemical substances, it can take a number of years to manifest,” he said.
“People exposed over a lifetime are dying in their 50s to 70s, which is why we are working at preventing exposures today.”
Between 2001 and 2010, the number of fatal claims accepted by WorkSafe-BC attributed to worksite trauma dropped from 43 percent to 29 percent. Fatal accidents, due to work related motor vehicle accidents, also dropped to 19 per cent from 22 per cent. The percentage of accepted fatal claims due to occupational disease rose from 32 percent in 2001 to 52 percent in 2010.
“We can’t do much for those exposed before, but we can help prevent future exposure,” Johnson said.“We put out a notice this time last year for individuals to think about exposure and have the measures in place to show how workers can protect themselves and employees too.
“We are asking employers to take the regulations more seriously and apply the same responsibility in this area, as in the area of exposure to other dusts,” Johnson said.
Crystalline silica dust, commonly found in sand, rock and building materials, such as concrete and brick, is released into the air each time these materials are cut, ground or drilled.
Breathing the particles in concentrations higher than recommended exposure limits can result in permanent lung damage.
The exposure limit for respirable crystalline silica (including quartz) is 0.025 milligrams per cubic metre (mg/m3)—a concentration workers could be exposed to eight hours per day, five days per week, without adverse health affects, according to the occupational health and safety regulation.
As a suspected carcinogen, however, crystalline silica is considered an ALARA substance, meaning exposures must be reduced to levels As Low As Reasonably Achievable, below the recommended limit. Airborne silica mainly affects people working with rock, concrete, masonry, asphalt or heavy steel. Abrasive blasting, tile cutting, tuck point grinding, some structural demolition and clean-up, among other activities, can expose workers to unsafe levels.
Chronic silicosis develops after 10 or more years of exposure in relatively low doses.
Accelerated silicosis develops five to 10 years after initial exposure to crystalline silica at high concentrations. Acute silicosis can occur anywhere from a few weeks to four to five years after exposure to extremely high concentrations of the dust. Symptoms include shortness of breath, severe cough and weakness, and can become progressively worse.
It sometimes results in death. Under Section 5.54 (Exposure control plan) of Occupational Health and Safety Regulations, employers are required to develop an exposure control plan in any cases where employees may be exposed to airborne silica dust in excess of 50 per cent of the exposure limit.
According to the Yukon Workers’Compensation Health and Safety Board worker exposure to crystalline silica and other air contaminants often goes unchecked because some companies lack organized respiratory protection programs or sufficient employee training. Some purchasers of construction are also making safety a priority.
“Any contractor engaged to perform work for VIHA (Vancouver Island Health Authority) is given a site safety orientation session that includes silica dust control and an overview of what dust control measures are expected pertaining to CSA Z317.13-07,” said Dean Anderson, director, facilities maintenance and operation for VIHA.
VIHA’s Silica Exposure Control Plan requires workers to wear a respirator to drill a single hole in concrete and during general clean-up.
Johnson said Wo r k S a f e BC’s campaign is asking employers to take the issue more seriously and overcome a dated culture in the industry that may not take safety equipment seriously.
“Ten years ago, no one wore a respirator, but today not so much,” he said.
“Now a respirator is a standard piece of equipment that anyone working with these substances should use. There are also vacuum cleaners that capture concrete grinding dust and drills with built in vacuums.”Ideally, construction projects can control exposure with silicafree alternative materials, such as crushed glass used in abrasive blasting.
Another option is the call for building designs with pre-built recesses for plumbing, gas and electric wiring, which would require less cutting or drilling of concrete. Local exhaust ventilation or water spray systems can reduce dust levels, as can physical barriers that separate the affected area from unprotected workers.
Air monitoring can ensure restrictive exposure limits are not exceeded, or if they are, that workers are sufficiently protected with personal protective devices.
“Exposures in the construction industry come down to knowing what you are working with,” said Johnson.
“If you are going to roll on paint, you want to know if it contains lead or chemicals.
“And, if you are drilling, you should know if what you are drilling has silica in it.”
Study planned for ways to control road dust using dust suppression equipment
By Dale Wetzel, The Associated Press
BISMARCK, N.D. -A former top North Dakota health official will direct a study to explore the best ways to control dust clouds kicked up by the heavy truck traffic that has accompanied western North Dakota's oil boom.
North Dakota's Industrial Commission on Tuesday approved contributing $220,000 to the cost of the study. It will be done next spring, using unpaved stretches of road in Dunn and McKenzie counties as experiment sites. The stretches of road will be a half-mile to a mile long.
"The dust is terrible. It's very noticeable. You can't drive a pickup down the road without getting a film of dust on the truck bed every time you move around," said Gov. Jack Dalrymple, the chairman of the Industrial Commission. "It is a problem, and we have to find some creative solutions."
The study will test various dust-control methods, including spreading chemicals that draw water from the air, thus keeping the road's surface damp, and substances that bind the soil together.
One popular dust suppressant, magnesium chloride, helps to keep a road surface damp. However, the chemical can make a road's surface slippery when it is wet, and it does not do well at keeping dust down during extended dry periods.
Francis Schwindt, a former environmental health chief in the North Dakota Department of Health, is directing the study. Schwindt retired from the Health Department in 2002.
His research proposal said he hopes to discover dust-control techniques that can be used statewide. If control of road dust in western North Dakota's oil-producing region does not improve, oil production itself could be curtailed, he said. "A partial shutdown of oilfield traffic occurred this spring due to the flooding and wet, soft roads. The opposite may also be true," the research proposal says. "If extended drought conditions occur in the future, counties may be forced to limit traffic to reduce unsafe travel conditions and impacts to crops and county residents."
Dust control rules and regulations have become more strict
In response to an EPA ultimatum, the Maricopa Association of Governments (MAG), Maricopa County, the Arizona Department of Environmental Quality and other regulatory agencies have devised a State Implementation Plan to bring the Phoenix area into compliance with federal dust-control requirements. Consequently, the County is cracking down on dust-control violations, with particular scrutiny on construction sites.
Fines handed out to contractors and developers are multiplying as the County takes additional measures to meet the EPA deadline. In 2007, fines paid for Maricopa County air quality violations exceeded $5.3 million, up from $3.7 million in 2006. Individual fines in December 2007 reached $98,500. The assessment trend is continuing in 2008.
In the Phoenix area, Maricopa County Air Quality Department (MCAQD) has increased the number of compliance inspectors (from eight to more than 50) and is expected to have more than 90 in the field before the end of 2008. Additionally, MCAQD has revised the local air-quality rules to include more stringent standards for fine particulate matter and to refine detection methods for determining pollutant concentrations.
The regulatory burden grew heavier on March 26, 2008, when subcontractors became regulatory targets and the County deployed an expanded inspection force.
The Maricopa County Air Quality Department has posted a draft of the more stringent rules at www.maricopa.gov/aq (click on "Rules & Regulations"). These new measures (see a one-page summary) include limiting track-out, cutting time between when land is cleared and construction started, and prohibiting visible dust from crossing property lines.
To comply with the crackdown on dust emissions, local contractors and developers must implement effective control measures and work strategies. (Subcontractors are not required to have a dust-control plan, per se, but, as noted above, they must register and pay a fee. In addition, subcontractors can be cited for violations of their own making.) Developing a plan usually begins with a dust-control permit, which the County requires on all jobsites that will disturb more than a tenth of an acre.
To obtain a permit, a contractor must first submit a dust-control plan for County approval. A dust-control plan involves the implementation of control measures before, during and after conducting any dust-generating operation. (On sites larger than five acres, the permit holder must designate an employee responsible for dust-control plan compliance.) Common control measures include watering, using wind barriers, maintaining and cleaning vehicles, chemically stabilizing the soil, and using track-out control devices. To develop a dust-control plan and contingency measures, it may be useful to engage the services of an environmental consulting firm.
Once a dust-control plan has been formulated, it is the contractor's responsibility to: read and understand the dust-control permit and plan and have them available at the jobsite; use contingency control measures when primary controls are ineffective; implement the dust-control plan and ensure that all employees, workers and subcontractors know their responsibilities; monitor the worksite for compliance with the dust-control plan; and keep a daily log monitoring the implementation and effectiveness of the control measures.
While it is not officially required, contractor designation of a dust-control site coordinator has shown to be a sound and, for all practical purposes, necessary component of a dust-control plan. The site coordinator must have authority over dust issues, and he should have a fully trained backup to serve in his capacity during his absence.
The consequences of noncompliance are not limited to the fines discussed earlier. Any entity or person who violates the MCAQD rules may be subject to injunctive measures that bring all work to a halt. Further, violators may be subject to misdemeanor or felony charges. Moreover, if a contractor fails to comply, the owner or developer may also be held responsible for the violation.
