Silver Spring, MD — A new e-tool from CPWR – The Center for Construction Research and Training is intended to help manufacturers, distributors and importers of products that contain nanomaterials strengthen their Safety Data Sheets.

The free, interactive Nano Safety Data Sheet Improvement Tool poses to users a series of questions to help evaluate their existing SDSs, and then generates a report with recommendations for improvement. That report is based on the 16 sections of an SDS required by OSHA that follow specifications of the Globally Harmonized System of Classification and Labeling of Chemicals.

Nanomaterials – materials that have at least one dimension (height, width or length) that’s smaller than 100 nanometers – are chemical substances whose microscopic size gives them properties they don’t possess in their larger form.

CPWR has identified more than 800 nanomaterials that are increasingly being used in construction. Those materials include sealants, coatings, paints, concrete, flooring, lubricants and roofing materials. When workers use the materials, they can be exposed to fumes, gases, vapors and dust containing nanomaterials, which can present health hazards.

Knowing which materials could be hazardous allows workers to take precautions to mitigate the risks, according to CPWR, which says SDSs for these products should clearly identify nanomaterials that are present and offer information on potential safety and health risks.

2019 study led by Laura Hodson, the retired coordinator of the NIOSH Nanotechnology Research Center, revealed that only 3% of the nanomaterial SDSs evaluated were satisfactory and 79% needed significant improvement.

Rockville, MD — OSHA requirements for mechanical service and mechanical construction on low-slope roofs – and the differences between them – are the topic of a new poster from the Mechanical Contractors Association of America.

Mechanical service is covered under OSHA’s general industry standards (1910), while mechanical construction is covered under the agency’s construction standards (1926).

According to MCAA, OSHA’s position on mechanical service is that the work “does not meet the definition of ‘temporary and infrequent’ if the job task takes longer than it would to install or set up fall protection, and the task is performed more than once a month, once a year or when needed.”

On the poster, MCA says it’s “working to establish a reasonable interpretation of the standard.”

For mechanical construction, workers must use fall prevention systems or fall protection when working 6 feet or more above a lower level. No safe distance exists for a worker to perform tasks without fall protection on a low-slope roof in this situation. (One exception involving a 15-foot or longer warning line is detailed in the poster.)

MCAA represents around 2,600 companies involved in heating, ventilating and air conditioning; refrigeration; plumbing; piping; and mechanical service.

COVID-19 and Construction

First published by Safety+Health an NSC publication

CPWR report highlights pandemic’s impacts

Silver Spring, MD — The rate of nonfatal illnesses in the construction industry jumped 81.4% during the first year of the COVID-19 pandemic compared with the annual average for the previous four years, according to a new report from CPWR – The Center for Construction Research and Training.

Using data from that covered different time periods from 2016 to 2022, researchers found that the rate of nonfatal illnesses in the construction industry increased to 12.7 per 10,000 full-time equivalent workers in 2020 from an average of 7.0 per 10,000 FTEs over the four previous years. Overall, around 8,700 nonfatal illnesses were recorded in 2020, compared with an annual average of 4,600 over the previous four years.

The number of nonfatal respiratory illnesses increased to 5,300 in 2020 from an annual average of 425 from 2016 to 2019. That equates to a large spike in the rate per 10,000 FTEs, to 7.7 from 0.6 – a 1,183% increase.

Looking at COVID-19 vaccination rates by major occupational category in May, construction and extraction workers (52.4%) trailed all others and lagged far behind the percentage for all industries, which was 81.7. Those workers’ top reasons for not getting vaccinated, according to a Delphi Group survey that allowed respondents to choose more than one, were:

  • Distrust of COVID-19 vaccines (61.4%)
  • Distrust of the government (59.2%)
  • Don’t need a vaccine (58.7%)
  • Worried about side effects (55.8%)

“Construction work was deemed essential early in the pandemic,” the report states. “One of the most important steps to keeping construction workers safe on the worksite is the COVID-19 vaccine. The dramatic increases in nonfatal respiratory illnesses among construction workers highlight the pandemic’s impact on construction worker safety and health and the need for vaccinations.”

CPWR highlights its COVID-19 Construction Clearinghouse among its resources “on the science and benefits of the COVID-19 vaccine.”

‘Take-home toxins’: Study shows construction workers may be putting family at risk

First published by Safety+Health an NSC publication

Boston — Construction workers are at increased risk of unintentionally tracking various toxic metals from the jobsite into their homes – potentially putting family members at risk, results of a recent study show.

Researchers from Boston University’s School of Public Health and Harvard University’s T.H. Chan School of Public Health visited the homes of 27 workers (21 in construction) who had at least one child to collect dust samples and make observations. They identified and measured for 30 different toxic metals. The workers completed a questionnaire regarding work- and home-related practices that could affect exposure.

Results showed that the construction workers’ homes had higher concentrations of arsenic, chromium, copper, manganese, lead, nickel and tin dust than the homes of the other workers, who had janitorial or automobile repair jobs.

The higher concentrations were associated with worker factors such as lower education, not having a work locker to store clothes, mixing work and personal items, not having a place to launder clothes, and not washing hands and changing clothes after work.

The researchers say the new data underscores the need for more proactive and preventive measures to reduce so-called “take-home toxins,” including policies, resources and education for workers and their families.

“Many professions are exposed to toxic metals at work, but construction workers have a more difficult job implementing safe practices when leaving the worksite because of the type of transient outdoor environments where they work, and the lack of training on these topics,” lead study author Diana Ceballos, an assistant professor of environmental health and director of the Exposure Biology Research Laboratory at BU, said in a press release. “It is inevitable that these toxic metals will migrate to the homes, families and communities of exposed workers.”

Ceballos adds that the issue is compounded when construction workers live in disadvantaged communities or substandard housing that may already contain toxic metals.

The study is scheduled to be published in the June issue of the journal Environmental Research.

Washington — The third annual National Stand-Down to Prevent Struck-By Incidents is expanding to a full week from a one-day event.

Set to take place April 11-15, the stand-down is a collaborative effort led by NIOSH’s National Occupational Research Agenda Construction Sector Council. The event, scheduled in conjunction with National Work Zone Awareness Week, is aimed at raising awareness of struck-by hazards and ways to prevent them. According to OSHA, the four most common struck-by hazards are being struck by a flying, falling, swinging or rolling object.

CPWR – The Center for Construction Research and Training and the NORA Construction Sector Council’s struck-by work group have scheduled a series of webinars throughout the week. Topics will include work zone safety, lift zone safety, heavy equipment and dropped objects.

CPWR also is offering various online resources, including infographics, toolbox talks, research and two on-demand webinars from last year’s stand-down: Cranes & Lifting – Avoiding Struck-By Incidents Under the Hook and Preventing Struck-By Incidents: Learning by Experience.

New toolbox talk from CPWR

Silver Spring, MD — A toolbox talk recently published by CPWR – The Center for Construction Research and Training features guidance on planning a safe lift with a crane.

The resource – available in English and Spanish – includes a short story and subsequent questions to consider, safety tips, and a way to communicate how organizations can “stay safe today.”

Among CPWR’s recommendations is to conduct a lift planning meeting with all workers involved before beginning. Additionally, don’t lift a load that exceeds the capacity of the crane or rigging; monitor the weather, ground conditions and other environmental factors; and keep the crane clear of obstructions such as overhead power lines.

“Before a lift, it is important for everyone involved to understand their roles, the hazards associated with rigging and hoisting, and how to safely execute the lift to prevent any injuries or fatalities,” CPWR says.

Construction workers at higher risk of COPD, study shows

First published by Safety+Health an NSC publication

Silver Spring, MD — Workers in construction trades are at “significantly” higher risk for chronic obstructive pulmonary disease than non-construction workers, according to the results of a recent study.

A team of researchers from CPWR – The Center for Construction Research and Training, Duke University and the University of Maryland studied nearly 18,000 participants in the Building Trades Medical Screening Program, or BTMed, to determine the risk of COPD among different trades. The study involved a larger cohort than a 2010 study of construction workers at U.S. Department of Energy nuclear facilities who participated in the BTMed. Those workers were found to have increased COPD risk, according to CPWR.

Overall, 13.4% of the participants had COPD and more than two-thirds of the cases were classified as moderate to severe. Compared with non-construction workers, the participants had a 1.34 times greater risk of COPD and a 1.61 times higher risk of severe COPD.

The trades with the highest level of risk were cement masons/bricklayers (2.36 times) and roofers (2.22).

Based on the new findings, the researchers say additional preventive measures are needed to reduce workplace exposures to vapors, gases, dusts and fumes to reduce the risk of COPD. In addition, workers who smoke can benefit from cessation support and advice.

The study was published in the American Journal of Industrial Medicine.

Silver Spring, MD — Mitigating the spread of COVID-19 on construction sites should be a team effort, OSHA Directorate of Construction Director Scott Ketcham said during a Feb. 25 webinar.

Hosted by OSHA, NIOSH, and CPWR – The Center for Construction Research and Training, the event focused on helping construction employers and workers identify exposure risks and determine appropriate control measures.

Ketcham detailed how updated COVID-19 guidance issued by OSHA on Jan. 29 affects construction employers and workers. He also noted that safety professionals still need to contend with other hazards during the pandemic.

“Controlling this disease process with coronavirus and mitigating other hazards really takes all of us working together,” he said. “We all know that in the construction industry we have multiple trades working on a construction site for different companies. Coordination of efforts to make sure that we’re looking out for one another and protecting one another is important.”

Ketcham added that OSHA will use the multi-employer work policy to assess how contractors are following the guidance on construction sites.

Amanda Edens, deputy assistant secretary of labor for occupational safety and health at OSHA, acknowledged that new and updated guidance can lead to confusion among federal agencies and employers.

“It’s challenging for OSHA and CDC to give guidance because science changes,” she said. “And it’s challenging for employers too because they’re trying to keep up with what we’re learning as we go.”

Edens said worker safety issues such as trenching and cranes have remained a priority throughout the pandemic, and topped by those related to COVID-19.

“The bread-and-butter work of the agency continues,” she said. “We still have a lot of construction work to get done, even if COVID wasn’t around. But it is, so we have to do that work and do it in a COVID environment.”

Timothy Irving, deputy director of OSHA’s Directorate of Construction, encouraged employers to consider the mental health needs of workers as he discussed nontraditional hazards.

“OSHA might not be the first federal agency you think of when you hear about nontraditional workplace conditions – PTSD, drug use, suicide and other mental health issues,” he said. “But our mission is to prevent work-related injuries, illnesses and deaths.”

OSHA’s suicide prevention webpage provides multiple resources to assist workers who might be in crisis. When providing resources to workers, Irving said employers should consider a wide variety of helpful information.

“When you share health and safety resources, be aware that mental health is a part of health and safety,” he said.

Trench Safety Stand Down set for June 15-19

trenching.jpg

Fairfax, VA — The National Utility Contractors Association, with support from OSHA and the North American Excavation Shoring Association, is calling on employers involved in trench work to participate in the fifth annual Trench Safety Stand Down, scheduled for June 15-19.

The event is intended to raise awareness of the dangers of trenching and excavation, as well as promote the use of protective systems such as sloping, shoring and shielding. The OSHA standard for trenching and excavation (29 CFR 1926.650, Subpart P) requires protective systems for trenches that are 5 feet or deeper, unless the excavation occurs in stable rock.

As part of the event, NUCA, NAXSA and OSHA are offering free online tools, including posters, checklists, fact sheets and videos.

OSHA cautions that 1 cubic yard of soil can weigh as much as 3,000 pounds, and adds that trench collapses are “rarely survivable.” According to NUCA, citing data from OSHA, 17 workers died in trench incidents in 2018.

As a result of previously successful campaigns, NUCA has expanded upon the stand-down and declared June the inaugural Trench Safety Month, a May 20 organizational press release states.

“In this industry, the safety of our employees on the jobsite is our top priority,” NUCA CEO Doug Carlson said in the release. “Making this June ‘Trench Safety Month’ emphasizes the valuable training and experiences our members’ employees are gaining through the Trench Safety Stand Down week held annually in June throughout our industry.”

COVID-19 pandemic: Construction workers subject of new OSHA alert

Washington — Aimed at protecting construction workers from exposure to COVID-19, a new OSHA safety alert lists measures employers should take during the pandemic.

Released April 21, the alert calls on employers to encourage workers to report any safety or health concerns and stay home when sick. Additionally, the agency recommends that in-person meetings, including toolbox talks and safety meetings, be kept as short as possible. Organizations should limit the number of workers in attendance and make sure they remain at least 6 feet apart from each other at all times.

Employers also should ensure alcohol-based wipes are used to clean tools and equipment – especially those that are shared – before and after use. Workers tasked with cleaning should consult manufacturer recommendations for proper use and any restrictions.

Physical distancing protocol should be followed inside work trailers or when visitors are onsite, and physical contact should be avoided.

Organizations are advised to clean and disinfect jobsite toilets on a regular basis, and ensure hand-sanitizer dispensers are filled. Any other frequently touched items such as door pulls should be cleaned and disinfected.

Other recommendations:

  • Educate workers on the proper way to put on, take off, maintain and use/wear protective clothing and equipment.
  • Allow workers to wear masks over their nose and mouth to prevent the spread of COVID-19.
  • Encourage respiratory etiquette, including covering coughs and sneezes.
  • Use cleaning products listed by the Environmental Protection Agency as effective against the coronavirus (SARS-CoV-2) that causes COVID-19.
  • Promote personal hygiene. If workers don’t have access to soap and water for handwashing, provide hand sanitizers that contain at least 60% alcohol.
  • Continue to use “normal control measures,” including personal protective equipment, to safeguard workers from other job hazards associated with construction activities.

The alert is available in English and Spanish.
