Washington — Managing and controlling combustible dust should be considered a unique hazard – not simply “tidying up the place,” the Chemical Safety Board says in a recently released learning review document that includes input from workers and industry stakeholders.

Prepared by Dynamic Inquiry LLC on behalf of the agency, the 47-page document compiles feedback solicited by CSB in a Call to Action – issued in October 2018 – stemming from a May 2017 explosion and fire that killed five workers and injured 14 others at the Didion Milling Co. facility in Cambria, WI. The agency sought comments on the management, control and understanding of combustible dust.

“This learning review represents a new method for the CSB to examine an incident,” CSB Chair and CEO Katherine Lemos said in a Sept. 10 press release. “The outcome of this specific review provides an opportunity for dust hazards to be examined from multiple perspectives, which may allow for a greater understanding of preexisting assumptions and scenarios.”

CSB said it found that more efficient sharing of information between companies, industries and regulators – facilitated openly and without fear of punishment and reprisal – was the stakeholders’ most sought-after goal. Numerous respondents to the Call to Action indicated that a possible normalization of the risk contributed to the ongoing difficulty of keeping facilities dust-free.

Additionally, the document renews CSB’s long-standing call for OSHA to issue a standard on combustible dust. CSB identified 386 combustible dust incidents from 1980 to 2017 that resulted in 178 fatalities and more than 1,000 injuries.

Other recommendations for controlling and mitigating combustible dust hazards include:

  • Develop standards to certify dust collection system manufacturers, installation and training.
  • Advance psychological safety within organizations to improve the willingness of personnel to provide information and ask questions.
  • Explore ways to promote effective communication within and between facilities, including eliminating language barriers. “Even the words used to describe combustible dust can introduce vulnerabilities to the system,” the report states.
  • Acknowledge that training doesn’t always ensure learning. Create experiential and collaborative learning methods within facilities.
  • Establish an online forum and/or a “lessons learned center,” which allows the community to explore combustible dust issues and share feedback.

“CSB hopes that this product provides further insight and understanding of combustible dust hazards,” Lemos said. “Our goal is to continue to examine incidents from multiple perspectives to better enhance prevention and continually drive chemical safety.”

CVSA Releases 2020 Brake Safety Week Results

First published by CVSA.
Greenbelt, Maryland (Oct. 27, 2020) – During this year’s Brake Safety Week, 12% of the 43,565 commercial motor vehicles inspected were placed out of service for brake-related violations. Inspectors from Canada, Mexico and the U.S. removed 5,156 commercial motor vehicles from roadways due to brake violations during the week-long inspection and enforcement event, focused specifically on reducing brake-related crashes by conducting inspections and identifying and removing unsafe commercial motor vehicles from roadways.

Fifty-three jurisdictions participated in this year’s Brake Safety Week, which is a voluntary inspection, enforcement and outreach initiative. In light of the coronavirus pandemic, jurisdictions that elected to participate in Brake Safety Week, which took place Aug. 23-29, 2020, conducted inspections following each agency’s health and safety protocols and precautions in consideration of the health and well-being of inspectors and drivers.

Forty-five U.S. jurisdictions, seven Canadian jurisdictions and Mexico’s National Guard and the Ministry of Communications and Transportation provided data this year. In the U.S., 35,778 inspections were conducted; 4,565 vehicles (13%) were placed out of service for brake-related violations. In Mexico, 6% (355) of the 5,958 commercial motor vehicles inspected were placed out of service for brake-related violations. In Canada, 1,829 inspections were conducted, and the brake-related out-of-service rate was 14% (256).

Commercial motor vehicle inspectors throughout North America use the Commercial Vehicle Safety Alliance’s (CVSA) North American Standard Out-of-Service Criteria to identify critical vehicle inspection item violations that are concerning enough to warrant removing that vehicle from traveling on roadways until those conditions have been repaired.

Eighty-eight percent of the commercial motor vehicles inspected did not have brake-related critical vehicle inspection item violations. Vehicles that did not have any out-of-service conditions during a Level I or Level V Inspection may have received a CVSA decal. A decal, valid for up to three months, signifies that the vehicle was recently inspected by a CVSA-certified inspector and that vehicle had no critical vehicle inspection item violations.

In addition to capturing brake system out-of-service violation data, during this year’s Brake Safety Week, inspectors also recorded and submitted data regarding the chafing of brake hoses. Inspectors reported levels of brake hose chafing violations, separated into five categories based on the level of severity; two of which were out-of-service conditions, three were not.

A total of 6,697 hose chafing violations were reported in a separate data query from participating jurisdictions. Table 1 provides a reference key and details each category of chafing, along with the numeric totals for each category by country. Table 2 illustrates the frequency of each category of brake hose/tube chafing encountered by each country as a percentage of all hose chafing violations.

Table 2: Percentages of Total Brake Hose Chafing Violations
“Although many commercial motor vehicle enforcement agencies were forced to reduce services in the spring due to the pandemic, it was important that we resumed inspection and enforcement duties as soon as it was safe to do so,” said CVSA President Sgt. John Samis with the Delaware State Police. “With truck drivers designated ‘essential personnel’ by the government, we needed to ensure that the vehicles traversing our roadways were safe to support commercial drivers as they selflessly continued to work during such a difficult and challenging time.”

Next year’s Brake Safety Week is scheduled for Aug. 22-28, 2021.

Brake Safety Week is part of CVSA’s Operation Airbrake program, in partnership with the U.S. Federal Motor Carrier Safety Administration, the Canadian Council of Motor Transport Administrators, and Mexico’s National Guard and the Ministry of Communications and Transportation.

Communicating through a facemask

Communicating through a face mask, McCraren Compliance

First published by Safety+Health an NSC publication.

Wearing a facemask to help prevent the spread of COVID-19 can present obstacles to communication, “an important and complex transaction that depends on visual and, often, auditory cues,” says Debara L. Tucci, director of the National Institute on Deafness and Other Communication Disorders.

When facial coverings are worn, facial features are obscured, while speech perception and conveyed emotion are disrupted. Facial coverings also filter speech, making sounds less clear, Tucci said, adding, “When it is harder to understand speech – whether because of cloth face coverings, distance or other factors – research suggests that we have fewer cognitive resources to process information deeply. As a result, communication suffers, and feelings of stress and isolation may increase.”

NIDCD offers the following tips to improve communication when wearing a facial covering:
Be aware. Is the person you’re communicating with having trouble understanding you? Ask and adapt if needed.
Be patient. Facial coverings block visual cues and muffle sounds that help us understand speech, which can make interactions frustrating.
Be mindful. Consider how physical distancing might affect your communication. As distance increases, sound levels decrease and visual cues are more difficult to see.
Be loud and clear. Speak up, but don’t shout. Focus on speaking clearly. Consider wearing a clear facial covering, if possible. If you’re having trouble understanding, ask the person you’re talking with to speak louder. If you lip-read, ask those you interact with regularly to wear a clear facial covering.
Turn down the background volume. Background noise can make conversation especially hard. Move to a quieter spot or turn down the sound, when possible.
Communicate another way. Use a smartphone talk-to-text app or writing tools (e.g., paper/pen, whiteboard) to communicate.
Confirm your statement is clear. Ask if your message has been understood.
Bring a friend or be a friend. If it’s essential that you comprehend important spoken details – during a discussion with a health care provider, for example – consider bringing a friend or family member with you.

National Prescription Drug Take Back Day is Saturday, October 24

First published by  Get Smart About Drugs. 

Prescription Drug Take Back Day

Do you have unused or expired prescription medication in your home? If so, there’s a chance they could get into the wrong hands.

Clean out your cabinets, and drop off your meds at a designated location near you this Saturday, October 24, between 10 a.m. and 2 p.m. during Take Back Day.

This event is a safe, convenient, and responsible way to dispose of unused or expired prescription drugs at locations in communities throughout the country.

The October 2019 Take Back Day brought in 882,919 pounds (almost 442 tons) of unused or expired prescription medication and vape devices.

This brings the total amount of prescription drugs collected by DEA since the fall of 2010 to nearly 12.7 million pounds​. Read more about the most recent Take Back Day totals here.

Check DEA’s official Take Back Day website for more information and to find year-round collection sites near you.

In the Meantime… What Should You Do With Your Unused Meds?

Most people who misuse prescription drugs get them from family, friends, and acquaintances.

You can make a difference by keeping track of the medicine you have, by rethinking where and how you keep your medications in your home, and by safely disposing of any unused medications.

Don’t Share

Keep track of your legally prescribed controlled substances – that is, count your pills so you always know how much you should have and so you know when to take action if any go missing.  With controlled substances, sharing is NOT caring. You could be putting your loved ones at risk, and unintentionally contribute to drug misuse, drug addiction, or a fatal drug overdose. Read more about ways to secure your meds and safely dispose of them at home.

New method of detecting combustible dust uses real-time imaging

First published by Safety+Health an NSC publication.

West Lafayette, IN — Using newly developed algorithms, researchers from Purdue University have designed an image- and video-based application to detect combustible dust concentrations suspended in the air.

The application, which the researchers say can be used in agricultural, powder-handling or manufacturing settings, involves capturing images of a suspended dust cloud and then analyzing the light extinction coefficient. In testing, the algorithm was able to recognize 95% of sawdust and 93% of cornstarch particulates in the air, a university press release states, adding that the application was able to distinguish suspended dust from “normal background noise.”

Current technology for detecting dust levels can be expensive and difficult to install in workspaces, and separates dust matter into multiple filters that must be weighed and undergo additional analysis, according to the researchers. In contrast, the new application doesn’t require extended training, is location independent and doesn’t need to be permanently installed.

According to data from the Chemical Safety Board, between 2006 and 2017, 111 combustible dust incidents resulted in 66 worker deaths and 337 injuries in the United States.

“Determining suspended dust concentration allows employers to take appropriate safety measures before any location within the industry forms into an explosive atmosphere,” Kingsly Ambrose, an associate professor of agricultural and biological engineering, said in the release.

The research team, which has worked with the Purdue Research Foundation Office of Technology Commercialization to patent the technology, said the application can be used effectively in open and confined spaces.

The study was published online July 21 in the Journal of Loss Prevention in the Process Industries.

CVSA reacts to FMCSA rejection of personal conveyance petition

rejection of personal conveyance petition

First published by Safety+Health an NSC publication.

Washington — The Commercial Vehicle Safety Alliance is evaluating its next course of action after the Federal Motor Carrier Safety Administration on Sept. 18 denied a CVSA petition requesting that the agency update its definition of personal conveyance and clarify a mileage limit.

A letter written by FMCSA acting administrator Wiley Deck and addressed to CVSA Executive Director Collin Mooney claims that the CVSA proposal lacks a “sufficient safety basis” to proceed with rulemaking that “would essentially propose arbitrary limits without any evidence of safety critical events avoided.”

CVSA filed the petition in May, after FMCSA announced a controversial final rule the agency claims adds flexibility to hours-of-service regulations. The rule went into effect Sept. 29.

“We understand the agency’s position on personal conveyance,” Mooney told Safety+Health, “but we still believe that it’s not addressed adequately.”

In June 2018, FMCSA issued guidance intended to clarify both the agricultural commodities exemption and the personal conveyance provision in HOS regulations.

According to the agency, personal conveyance – a driver’s movement of a commercial motor vehicle for personal use – is considered off-duty status and therefore does not affect HOS limitations.

However, CVSA contends in the petition that the guidance is “incomplete” without establishing a maximum distance and/or time a CMV operator can travel under the personal conveyance provision, stating that “a driver could, in theory, drive hundreds of miles over the course of several hours” under this designation, increasing the risk of driver fatigue and impacting roadway safety.

“Even though the agency says that setting a distance or time limit would be arbitrary, on the flip side of things, having things wide open for personal conveyance now is open-ended in itself, which is the whole point in the petition – why it’s creating issues,” Mooney said. “Because it gives the motor carrier industry and drivers an opportunity to hide hours under the premise of personal conveyance, which in fact is a falsification of the hours of service of the records of duty status. So, by providing that loophole, that gateway to camouflage or hide hours, we feel, is very problematic and jeopardizes highway safety.”

Deck writes that the guidance remains “an appropriate response to the issue, given the lack of research and data to support the adoption of specific restrictions.”

According to the guidance – which is effective until June 7, 2023 – other examples of personal conveyance include, but aren’t limited to:

  • Time spent traveling to restaurants and entertainment facilities from en route lodging, such as a motel or truck stop.
  • Commuting between the driver’s terminal and his or her residence, between trailer-drop lots and the driver’s residence, and between worksites and the driver’s residence.
  • Time spent traveling in a motorcoach without passengers to en route lodging, or to restaurants or entertainment facilities and back to the lodging.
  • Time spent transporting personal property while off duty.
  • Authorized CMV use to travel home after working at an offsite location.
