This study aimed to investigate the pulmonary functions of silica-exposed workers and their health-related quality of life in an insulator manufacturing industry. Exposure to welding fumes may result in disorders of the pulmonary, cardiovascular, and reproductive systems. Welders are also at a greater risk of developing symptoms similar to those seen in individuals with idiopathic Parkinson’s disease.
While drug use is a problem among industrial workers nationwide, it raises particular concern in the oil patch as US production surges to record levels in what is already one of the nation’s most dangerous sectors. Inhalation of crystalline silica dust is second only to asbestos as a hazard to construction workers. This video discusses important things to know. Evaluation of Occupational Ocular Trauma: Are We Doing Enough To Promote Eye Safety in the Workplace? The use of eye PPE among workers who sustain an eye injury in the workplace remains low.
Investigating the causal factors of electric line worker incidents is of high priority due to the decades-long record of incidents in the electric power industry. According to Bureau of Labor Statistics (BLS, 2018), 152 electrical line installer fatalities occurred in the U.S. in 2011 through 2016. For the individual years, the fatality numbers were 26, 27, 27, 25, 26 and 21, respectively. These rates often account for the ranking of electric line installers among the most dangerous professions in the U.S. Major contributors to electric line work incidents include electrocutions, machines, tools and vehicles (BLS, 2018). Closer inspection of these contributors reveals that their antecedents consist of attentional, strategic or knowledge factors (Reason, 1997). The study presented in this article investigates the role of sustained attention as a primary contributor to electric line worker incidents.
Little research exists concerning the safety of electric power line installers and, to the authors’ knowledge, no research is available regarding attentiveness as a causal factor of installer incidents. Specifically, the effect of sustained attention and vigilance (cognitive skills of immediate relevance to incident prevention for these workers) has not been examined. Past studies of cognitive-training regimens have evaluated both the effect on the trained task and transfer of training benefit to related but untrained cognitive tasks.
We strive for excellence. Such excellence continuously moves to higher standards and to cover more scope. Using another terminology, it is about continuous improvement built upon the realization from learning through experiences. With this as our guiding concept, the long-term value is about developing a framework that drives itself towards enhancement, towards self-governance.
The HSE preparedness standards are guided by the capability to predict scenarios of the future. Specifically, context-shaped scenarios based on very focused activities that include the environmental (nature), material (equipment & tools), procedural (operating processes) and the human (mindFLEX) dimensions. The core element towards superior HSE standards remains at the human level - the core. It is the individual / group mental and behavioural capabilities that become the blueprint, the engine, the calibrator and enhancer of HSE.
If operational excellence is the objective, the people behind it are to sculpture its shape, define its course and develop a behavioural internalization programme. Their behavior then becomes the expression of what their brain is made of. It is therefore the objective to assess, develop and guide brains to have what it takes towards HSE excellence.
A signal conveys information about the nature or characteristics of some phenomenon or event . Whether generated through communication systems, geophysical earth sounding or the human brain, researchers are trying to uncover and understand what this information means. Raw signal mixed with associated extraneous internal or external noise is often difficult to interpret. Thus, the use of signal processing to elucidate a recognizable and interpretable signal is almost always necessary. Can what we learn from one discipline with respect to signal processing be transferable to another? This study attempts to cross that bridge by using geophysical algorithms, routinely used in oil and gas exploration, to process brain signals elicited during a task, as measured through EEG recordings.

Insomnia is a common problem in offshore shift-work environments. In rotating shift-work environments, daylight and darkness cues are incongruent with sleep and work schedules. As a result, many shift workers find it hard to adapt to the schedule, resulting in suboptimal sleeping patterns and increased workforce fatigue. This paper presents a scientific method for reducing fatigue risks in oil and gas organizations that operate a slowly rotating shift schedule. Sleep and Fatigue in Offshore Shift-Work Environments Humans are diurnal (i.e., day animals); because of this, our circadian rhythm is programmed to ensure that alertness, concentration, and other aspects relating to job performance are highest during the day.
Fatigue is a known contributor to accidents. The potential for fatigue-related accidents also exists in the oil and energy industry.
Fatigue risk management systems commonly involve review and adjustment of employee rosters and job functions to assist employees with getting rest based on their work demands. Although this approach is reasonable, it assumes that by giving the employee the ability to rest, that he/she will return refreshed. Certain medical conditions may inhibit an employee's ability to rest.
Obstructive sleep apnea (OSA) is a medical condition where the patient has an airway obstruction which occurs when muscles in the upper airway relax while sleeping. This obstruction forces them to awaken, and if untreated, may lead to adverse medical conditions. For these patients, hours of work may not correlate as well with level of fatigue. Although there are many factors for OSA, the one most relevant for this abstract is Body Mass Index (BMI). In the adult population, OSA is estimated to be approximately 25% to 45% higher in obese subjects. The odds of having OSA increases as BMI rises and for individuals with a BMI of >35.
We will describe risk factors for OSA, treatment of the condition, as well as methods to reduce fatigue related risk. The discussion will include key components of a medical screening program as well as health and wellness programming that can be considered in parallel with any Fatigue Risk Management System.
Biometric data can be utilized to help predict the risk of fatigue related accidents in the workplace. By addressing the risks and providing solutions these incidents may decrease.
We will explore current OSA screening criteria, work hours limitations, and health and wellness programs as they relate to reducing risk. Most importantly, we will discuss a significant shortcoming with the identification of high risk individuals and an easy approach to help mitigate this risk.
Exposure to welding fumes may result in disorders of the pulmonary, cardiovascular, and reproductive systems. Welders are also at a greater risk of developing symptoms similar to those seen in individuals with idiopathic Parkinson’s disease. In welders, there are studies that suggest that alterations in circulating prolactin concentrations may be indicative of injury to the dopamine (DA) neurons in the substantia nigra. Exposure to welding fume particulate resulted in the accumulation of various metals in the pituitary and testes of rats, along with changes in hypothalamic TH and serum prolactin levels. Exposure to particulates with high concentrations of soluble manganese (Mn) appeared to exert the greatest influence on TH activity levels and serum prolactin concentrations.
Historical Perspective on Medical Marijuana
The Chinese Emperor Shen Nung, in 2737 B.C., described the therapeutic use of marijuana for joint pain, constipation, malaria, and childbirth. Therapeutic and religious use achieved great popularity in India around 1000 B.C. Medicinal use of marijuana continued, and spread to Africa, the Middle East, and the Arabian Peninsula into the 18th century.
Marijuana was introduced into western medicine by a physician, W.B. O’Shaughnessy who, in 1839, described its use for pain control, muscle relaxation, appetite stimulation, and as a treatment for nausea, and for seizures. The psychiatrist Moreau, in 1845, published an article describing the use of marijuana in his patients. In 1850, marijuana was added to the U.S. Pharmacopoeia. Information regarding medical uses of marijuana disseminated throughout North America and Europe. By 1900, more than 100 scientific articles had been published on medical marijuana. Marijuana extracts were being marketed by prominent pharmaceutical companies.
Use of marijuana declined in the U.S. from 1900 through the 1930s due to difficulty in standardizing preparations, development of alternative “mainstream” pharmaceuticals, and taxation by the Federal Marijuana Tax Act of 1937. By the 1930s, there were at least 2000 medicines, with over 280 manufacturers. Marijuana was removed from the U.S. Pharmacopoeia in 1942. In 1970, The Controlled Substances Act classified marijuana as a “Schedule 1” drug, in the same category as heroin.1
Mechanism of Action of Marijuana
Marijuana is a synonym (slang) for cannabis, which is derived from the marijuana plant, Cannabis sativa. The primary active constituents in the marijuana plant are Delta9- tetrahydrocannabinol (THC) and Cannabidiol (CBD).2 The human body has a receptor-signaling system for marijuana known as the Endogenous Cannabinoid System (ECS). The ECS has two types of receptors that activate very different bodily functions: CB1 receptors are very abundant in the brain, and solely mediate the behavioral, analgesic, and euphoric effects of marijuana (THC) (e.g., memory, cognition, perception, and pain). CB2 receptors are not very abundant in the brain, but are highly expressed in the gut and immune cells where they regulate inflammation and immune function. Cannabidiol (CBD) activates these receptors (e.g., anti-inflammatory, antiseizure, anti-nausea, and anti-anxiety).
Labeling is Easy: Dig Deeper to Change Behavior
It’s quite easy to give ourselves a label, isn’t it? We look at our behavior, and we look at how it affects others, and we give ourselves a label. I live up in the mountains of North Carolina and drive back roads all the time. Last summer I was driving in a city, was looking around at the unfamiliar surroundings, and drove right under the traffic light into an intersection. Just in case I wasn’t aware of my error, a guy in a big Bronco SUV blasted his horn and pulled beside me staring angrily. I looked at him and pointed to my head and mouthed “Stupid”. He seemed to agree and the confrontation was over. I had interpreted my own behavior with a label, “Stupid”, and that simple adjective seemed appropriate.
In fact, labeling is quite popular in modern business where management training often involves some personality test like the MBTI where we learn everyone’s label in hopes of better collaboration. “I’m an Introvert which explains my discomfort working in big teams.” “I’m a Judger which explains why I’m so critical.” Somehow these labels seem to be the magic elixir that make business work better. But they don’t. Everyone goes back to the same environment and acts the same way, nothing changes.
We overuse labels when dealing with the safety of our work crews and managers. The implication is: if workers can’t follow rules and procedures that are clearly in the manuals and training, and then they get hurt, they’re “Stupid”, “Noncompliant”, or “Lazy” or “___________” (you can fill in the blank – please keep it rated “PG”).
The problem is that you can’t fix a label. All the exhortations in the world emphasizing “Don’t BE this” won’t work. But we do that in our training, in our incident investigation summaries shared with workers, and in our personal conversations. But nothing changes. And you get frustrated. You can’t fix it. You’re left with nothing, except getting more and more upset.
Instead, consider what behavioral science tells us. Instead of asking a person to BE something, focus on how you can help them DO what is required to be safe. Don’t pretend and try to change someone. Leave that arrogance behind. Instead, be a servant.
