CDC - Sobering statistics on COVID among Healthcare Personnels

CDC released new statistics yesterday.  
One of the more sobering for the health care community are the number of cases and the number of fatalities within the health care community. This is made even more significant by the fact that CDC only has the mortality status for only 56.4% of the cases among health care personnel.
Cases & Deaths among Healthcare Personnel
Data were collected from 1,417,310 people, but healthcare personnel status was only available for 304,479 (21.5%) people. For the 66,447 cases of COVID-19 among healthcare personnel, death status was only available for 37,485 (56.4%).

OSHA Will Examine if Employers Determined Whether Employee COVID-19 Cases are Work Related for Purposes of Recording Workplace Injury and Illnesses

On May 19, 2019, OSHA issued another enforcement guidance memorandum
regarding recording COVID-19 cases that rescinds the prior guidance and obligates employers to make at least some work-related determinations regarding employees who contract COVID-19. The new memorandum goes into effect May 26, 2020, and will remain in effect until further notice.

By way of background, OSHA has explained that a COVID-19 case is a recordable illness if (1) an employee is positive or presumptively positive for COVID-19; (2) the case is work-related; and (3) the case results in medical treatment beyond first aid or days away from work. For employers, the "million-dollar" question remains: How does an employer determine whether an employee's COVID-19 case is work-related such that it is recordable on the employer's Injury and Illness logs?

OSHA's May 19 memorandum seeks to help employers address this question.

To start, OSHA will exercise its enforcement discretion to assess employers' efforts in making work-related determinations. This means that employers, at a minimum, must undertake an investigation to determine whether the COVID-19 case is work-related.

To this end, when an employer learns of an employee's COVID-19 illness, the employer should, at a minimum:

Ask the employee how he believes he contracted the COVID-19 illness;
While respecting employee privacy, discuss with the employee his work and out-of-work activities that may have led to the COVID-19 illness; and
Review the employee's work environment for potential COVID-19 exposure.

The employer should base its work-related determination should be based on the information reasonably available it at the time; however, if the employer later learns more information related to an employee's COVID-19 illness, the employer should then take that information into account and revisit whether the illness is work-related.

The memorandum explains that after a reasonable and good faith inquiry, if the employer cannot determine whether it is more likely than not that exposure in the workplace played a causal role with respect to a particular case of COVID-19, the employer does not need to record that COVID-19 illness.

The memorandum instructs Compliance Officers to consider the questions below when determining whether an employer has complied with its recording obligation. That is, evidence and information regarding answers to these questions may weigh in favor of or against work-relatedness.

News Release from OSHA: Revised Enforcement Policies For Coronavirus

OSHA Department of Labor, United States of America  
News Release

WASHINGTON, DC – The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) has adopted revised policies for enforcing OSHA's requirements with respect to coronavirus as economies reopen in states throughout the country.

Throughout the course of the pandemic, understanding about the transmission and prevention of infection has improved. The government and the private sector have taken rapid and evolving measures to slow the virus's spread, protect employees, and adapt to new ways of doing business.

Now, as states begin reopening their economies, OSHA has issued two revised enforcement policies to ensure employers are taking action to protect their employees.

First, OSHA is increasing in-person inspections at all types of workplaces. The new enforcement guidance reflects changing circumstances in which many non-critical businesses have begun to reopen in areas of lower community spread. The risk of transmission is lower in specific categories of workplaces, and personal protective equipment potentially needed for inspections is more widely available. OSHA staff will continue to prioritize COVID-19 inspections, and will utilize all enforcement tools as OSHA has historically done.

Second, OSHA is revising its previous enforcement policy for recording cases of coronavirus. Under OSHA's recordkeeping requirements, coronavirus is a recordable illness, and employers are responsible for recording cases of the coronavirus, if the case:

- Is confirmed as a coronavirus illness;
- Is work-related as defined by 29 CFR 1904.5; and
- Involves one or more of the general recording criteria in 29 CFR 1904.7, such as medical treatment beyond first aid or days away from work.

Under the new policy issued today, OSHA will enforce the recordkeeping requirements of 29 CFR 1904 for employee coronavirus illnesses for all employers. Given the nature of the disease and community spread, however, in many instances it remains difficult to determine whether a coronavirus illness is work-related, especially when an employee has experienced potential exposure both in and out of the workplace. OSHA's guidance emphasizes that employers must make reasonable efforts, based on the evidence available to the employer, to ascertain whether a particular case of coronavirus is work-related.

Recording a coronavirus illness does not mean that the employer has violated any OSHA standard. Following existing regulations, employers with 10 or fewer employees and certain employers in low hazard industries have no recording obligations; they need only report work-related coronavirus illnesses that result in a fatality or an employee's in-patient hospitalization, amputation, or loss of an eye.[1]

For further information and resources about the coronavirus disease, please visit OSHA's coronavirus webpage.

Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe and healthful workplaces for their employees. OSHA's role is to help ensure these conditions for America's working men and women by setting and enforcing standards, and providing training, education and assistance. For more information, visit www.osha.gov.

The mission of the Department of Labor is to foster, promote and develop the welfare of the wage earners, job seekers and retirees of the United States; improve working conditions; advance opportunities for profitable employment; and assure work-related benefits and rights.

35 years later, Bhopal gas leak failures resurface in Vizag

In Vizag, the 11 deaths so far and hundreds of affected people in hospital indicate that styrene must have escaped in extremely high concentrations and affected the nearby population.

Thirty six years after the Bhopal disaster, it is distressing to see accidents from hazardous industries. The fields of occupational and environmental medicine, toxicology, and epidemiology which study and prevent industrial accidents have still not been developed adequately to cater for the amount of industrial development that has occurred in India. After the Bhopal disaster, I was frustrated that this field was not available in India and I had to go overseas to study these subjects. In 2020, I'm not sure very much has changed.

Solar and Wind Cheapest Sources of Power in Most of the World

(BloomBerg) A decade ago, solar was more than $300 a megawatt-hour and onshore wind exceeded $100 per megawatt-hour. Today, onshore wind is $37 in the U.S. and $30 in Brazil, while solar is $38 in China, the cheapest sources of new electricity in those countries.

Battery storage is also getting more competitive. The levelized cost of electricity for batteries has fallen to $150 a megawatt-hour, about half of what it was two years ago. That's made it the cheapest new peaking-power technology in places that import gas, including Europe, China and Japan.

EPA Publishes Scope Documents for 20 Risk Evaluation Chemicals

(PAINT.ORG) This month, the U.S. Environmental Protection Agency (EPA) published 20 draft scope documents for high-priority chemicals undergoing Risk Evaluation under the Toxic Substances Control Act (TSCA). These are the 20 high priority chemicals that EPA designated for TSCA Risk Evaluation in December 2019.

EPA is accepting comments on the first 13 scoping documents, made available on April 6, through May 26. By statute, EPA must finalize scoping documents by June 20, 2020. Stakeholders must submit comment on the second batch of seven chemicals within 45 days of publication in the Federal Register. At this writing, EPA had not published in the Federal Register.

The scope documents include the proposed conditions of use, hazards, exposures, and the potentially exposed or susceptible subpopulations that EPA expects to consider in the TSCA risk evaluations. The documents also include: a description of the reasonably available information and the science approaches that EPA plans to use, a conceptual model that outlines the potential hazards and exposures throughout the life cycle of the chemical, an analysis plan to identify the approaches and methods EPA plans to use to assess health and environmental factors, and a potential plan for peer review.

Notably, EPA has not proposed exclusions for de minimis amounts. EPA may consider exclusions for de minimis amounts on a case-by-case basis, with supporting data. Information related to amounts in products or used in processes, exposures or controls/personal protective equipment (PPE) may be useful in seeking such an exemption.

EPA also generally includes disposal as a condition of use where it did not in the first 10 chemicals it evaluated. This is likely due to the 9th Circuit's opinion in Safer Chemicals, Healthy Families, et. al. v. EPA (No. 17-72260), where the 9th Circuit evaluated scope of EPA risk evaluations as required by EPA's risk evaluation framework rule.

The 20 Scoping Documents are as follows:

New class action launched over Pfas toxic firefighting chemicals used by defense

Lawyers have launched a new class action on behalf of tens of thousands of residents over the defense department's use of toxic firefighting chemicals.

The case will allege defence's use of per-and polyfluoroalkyl substances (Pfas) had "cataclysmic consequences" for residents in Wodonga, Darwin, Townsville, Wagga Wagga, Edinburgh and Bullsbrook.

The highly persistent and probable carcinogens were used for decades in firefighting foam on defence bases, leaching into nearby land and water supplies, contaminating food and accumulating in humans.

Residents near two other military bases – in Oakey, Queensland and Katherine, Northern Territory – reached a $212.5m settlement with the federal government over Pfas contamination in February.

U.S. Department of Labor Announces OSHA Interim Enforcement Response Plan to Protect Workers during the Coronavirus Pandemic

OSHA – The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) today announced an interim enforcement response plan for the coronavirus pandemic. The response plan provides instructions and guidance to OSHA Area Offices and compliance safety and health officers (CSHOs) for handling coronavirus-related complaints, referrals, and severe illness reports.

During the coronavirus outbreak, OSHA Area Offices will utilize their inspection resources to fulfill mission essential functions and protect workers exposed to the disease. The response plan contains interim procedures that allow flexibility and discretion for field offices to maximize OSHA's impact in securing safe workplaces in this evolving environment.

"OSHA is committed to protecting the health and safety of America's workers during this challenging time in our nation's history," Principal Deputy Assistant Secretary Loren Sweatt said. "Today's guidance outlines commonsense procedures for investigating complaints related to the coronavirus, while also ensuring the safety of workers, employers, and inspectors."

The response plan outlines procedures for addressing reports of workplace hazards related to the coronavirus. Fatalities and imminent danger exposures related to the coronavirus will be prioritized for on-site inspections. The response plan contains procedures and sample documentation for CSHOs to use during coronavirus-related inspections. Workers requesting inspections, complaining of coronavirus exposure, or reporting illnesses may be protected under one or more whistleblower statutes and will be informed of their protections from retaliation.

This memorandum will take effect immediately and remain in effect until further notice. It is intended to be time-limited to the current public health crisis. Check OSHA's webpage at http://www.osha.gov/coronavirus frequently for updates.

Toxnet Occupational Health relational database information moved to Haz-Map.

With the National Library of Medicine's decision to shutdown Toxnet much of its content moved to other NLM website, independent of NLM at

The content of the Haz-Map data tables is the same but the user interface has been improved. Improvements include adding chemical structures, adding popup tips to some agent fields, adding new agent and disease fields, alphabetizing chemical lists on base names of chemicals (without prefixes), and improvements in the user interface for both the computer and mobile devices.

On November 2019, Dr. Jay Brown completed the review of the first 1250 chemicals entered into the database. Review of the second 1250 chemicals added was started on March 5. He is busy checking spelling, hyperlinks, IARC classifications, TLVs, IDLHs, vapor pressures, and disease links.

If you have been a previous user of Haz-Map, I encourage you to view the new website and bookmark this new location in your Internet browser application.

Cancer risk among career firefighters are at increased risk for five cancers with typically stronger associations in those diagnosed younger than the age of 50

Male career firefighters in Florida are at increased risk for five cancers with typically stronger associations in those diagnosed younger than the age of 50, while there was evidence for increased thyroid and brain cancer, and possibly melanoma risk in female firefighters. Larger cohorts with adequate female representation, along with the collection of well‐characterized exposure histories, are needed to more precisely examine cancer risk in this occupational group.

EPA suspends enforcement of environmental laws amid coronavirus

(The Hill) "This EPA statement is essentially a nationwide waiver of environmental rules for the indefinite future. It tells companies across the country that they will not face enforcement even if they emit unlawful air and water pollution in violation of environmental laws, so long as they claim that those failures are in some way 'caused' by the virus pandemic. And it allows them an out on monitoring too, so we may never know how bad the violating pollution was," she wrote in a statement to The Hill.

The EPA has been under pressure from a number of industries, including the oil industry, to suspend enforcement of a number of environmental regulations due to the pandemic.

"EPA is committed to protecting human health and the environment, but recognizes challenges resulting from efforts to protect workers and the public from COVID-19 may directly impact the ability of regulated facilities to meet all federal regulatory requirements," EPA Administrator Andrew Wheeler said in a statement.

Health care workers need protection during pandemic: NUPGE and HSABC release new research showing higher precautions recommended

The National Union of Public and General Employees (NUPGE) and Health Sciences Association of BC (HSA) released today a research paper focused on respiratory protection for health workers caring for COVID-19 patients.

"Health care workers around the world are reporting that personal protective equipment guidelines are inconsistent and in short supply. As this pandemic hits our health care system in Canada, the priority must be to keep our health care workers healthy so they can provide the care patients need," said NUPGE President Larry Brown.

"HSA contacted Dr. John Murphy, an expert on occupational hygiene and adjunct professor at the Dalla Lana School of Public Health, University of Toronto, for science-based guidance on the best measures for infection control among health care workers. His research confirms that the best practice is to use N95 respiratory protection. This supports the position of other national health care unions in Canada, and the joint advice to members from unions across Canada," Brown said. See March 13, 2020 Joint Statement

"HSA represents more than 15,000 health science professionals working in our hospitals, including the respiratory therapists responsible for keeping patients in respiratory distress alive and the diagnostic technologists conducting the scans, x-rays, and other critical tests needed to diagnose hospitalized patients. When working with COVID-19 patients, a surgical mask is simply not the best practice for infection control. It is important our members know that and make sound decisions about how to best protect themselves while providing care," said HSA President Val Avery.

Recognizing the world-wide shortage of personal protective equipment, Dr. Murphy recommends that properly fit-tested N95 masks be prioritized for allocation based on assessment of the extent of potential exposure and risk, and that surgical masks be used as a back up. In all cases, eye protection must accompany respiratory protection.
