Safety Tidbit 6.06 – Open a Window to Reduce the Spread of Covid-19

Building on my last post from Adam DiCriscio, I want to add the simple act of opening a window periodically to help reduce the spread of Covid-19.

As Adam pointed out, the Covid-19 outbreak has significantly impacted our lives. It has changed how we work, shop, attend school, and more. According to a study done by the Pew Research Center, “nearly nine-in-ten U.S. adults say their life has changed at least a little as a result of the COVID-19 outbreak, including 44% who say their life has changed in a major way.” Nearly 2.5 Americans died every minute from Covid related issues yesterday (December 17, 2020).

The CDC advises us to stay six feet away from one another and to wear face coverings to help reduce the number of droplets being expelled from our mouths and noses when we cough, talk, or even breathe. Experts tell us that the outdoor environment is safer than the indoor one as there is significantly more clean, fresh dilution air.

The American Conference of Governmental Industrial Hygienists and the American Industrial Hygiene Association have each published their white papers on engineering controls indoors for the workplace. Primarily they say to increase dilution ventilation by increasing the amount of fresh outdoor air introduced into the workplace.

Now let’s turn our attention to our home living environment. Not many (probably no one) has an excellent HVAC system introducing fresh outside air and moving air around their homes. Some of us have forced air systems that pull air from the return vents, run the air through a generic filter, then heats and humidifies it, and blows the air back out into the living environment again. Sound familiar? Others have radiators that introduce heat but no air into the room.

So, how do we dilute the concentration of pathogens in our homes? We need to add new fresh air to the environment. We need to open a window. I know it’s cold out, so you probably don’t want to leave the window open all the time. However, I would advise you to open a window periodically to let in the fresh air. Think of how many smells are captured in your home when all the doors and windows are closed. There are pleasant odors from cooking, baking, or coffee brewing. However, think about the unpleasant odors such as dirty dishes, bathing, wet dog, or a cat box. If these odors are in your home, then so, possibly, is the COVID-19 virus.

All I ask is to consider opening a window for 15-20 minutes a few times during the day. Opening the window will help change out the odor-laden air inside your home with some fresh outdoor air.

The Covid-19 outbreak has significantly impacted our lives. It has changed how we work, shop, attend school, and more. According to a study done by the Pew Research Center, “nearly nine-in-ten U.S. adults say their life has changed at least a little as a result of the COVID-19 outbreak, including 44% who say their life has changed in a major way.”

 

The Centers for Disease Control and Prevention (CDC) tally of Covid-19 cases has reached over fifteen million, with thousands more added daily. Experts are suggesting that this pandemic may last until the end of 2021. The SARS-CoV-2 virus causes Covid-19. This virus can spread from person to person, and when an infected person coughs or sneezes, they release respiratory droplets into the air. Exposure to respiratory droplets is the primary route of transmission for the virus; however, an individual can get infected with SARS-CoV-2 by touching surfaces that contain the virus, followed by the individual touching their mouth, nose, and eyes. Each individual must take personal responsibility to help mitigate Covid-19.

 

To reduce the spread of SARS-Cov-2, everyone should practice proper hygiene and follow the recommended guidelines. Considering the primary way the virus can spread, airborne respiratory droplets, it is essential to practice social distancing. A minimum of six feet is the recommended distance between yourself and others when outside your home. If a person you live with is infected, you must keep at least six feet from them as well. Six feet is about two arm lengths. Face covering helps reduce the spread of the virus. Always wear a face cover when you are out in public; however, children under two or those who have trouble breathing should not wear a mask. Cover your mouth and nose when you have to cough or sneeze, and use a tissue or inside your elbow to trap the respiratory droplet.

 

There are also contaminated surfaces. All frequently touched surfaces should be clean and disinfected. First, clean the surface with soap and water, followed by a household disinfectant. Not all surfaces get clean regularly; therefore, frequently wash your hands. CDC guidance suggests washing your hands with soap and water for at least twenty seconds after touching any public surface or after sneezing or coughing. If washing your hands with soap and water is not an option, use a hand sanitizer with a minimum of 60% alcohol.

 

You should monitor your health every day. Check to see if you have any symptoms of Covid-19. The following symptoms are a good start but by no means an exhausted list: fever, coughing, shortness of breath, fatigue, muscle aches, headaches, loss of taste or smells, and diarrhea. CDC also recommends taking your temperature. If you feel any symptoms, stay home, but if you feel that your symptoms are severe, seek medical attention immediately.

 

In conclusion, each individual can play a part in reducing the spread of Covid-19. When we practice these guidelines, along with good hygiene, we can make a difference.

Forest fires devastated the Pacific US this summer. However, fire is a hazard that can be present in any workplace. Some workplaces are more prone to them based on the workload or the location.  Every organization should have a Fire Response protocol or policy, under their Emergency Action Plan, put in place so that employees and other personnel know what actions to take in the event of a fire.

 

Fires are a significant threat to the workplace. If a fire were to occur, it could be devastating to the facility and the equipment inside. Any people in the facility could also be in grave danger because they have a chance to become trapped by the fire with no way out. Aside from the organization itself, there are other things at risk when a fire occurs if it were to spread. If the fire gets out of hand, it can cause damages to the environment and the wildlife that lives in it. Communities and the individuals living in them can lose houses, which they may not replace, and even their own lives.

 

Having a Fire Response protocol or policy in place can ensure that the organization minimizes the chances of fire getting out of control or taking any lives. The policy should outline the steps to be taken if a fire were to occur secondly, what the facility would use internal and external fire response organizations. A detailed evacuation plan includes employee procedures and whether the facility will have a full or partial evacuation.

 

Internal fire response teams should select the number of individuals chosen by the employer to stay in the building and try to combat the blaze themselves. The employer must train these employees on the proper use of the apparatus and protective clothing used to fight the fire and to what extent they can fight the fire. The policy should include how often and what makes up these training exercises.

 

External fire response teams would include your local fire departments. They are more qualified and can handle larger fires that may occur. The policy should include what incidents they should be responding to and a plan for external fire response teams' functions. Within your plan, you should have the following information:

1. How to contact the response team

2. How to inform the response team of the facility layout, entry points,  site-specific operations, occupancies, vessels,

4. What hazards are present, and

5. What hose and couples there are and their location.

 

An evacuation plan is critical. This plan includes information on escape procedures, which personnel performs critical operations during an event, a method to account for all employees (such as a meeting place and roll call), how to report the emergency, and the names and contact information for any additional information.

References:      CDC - Impaired Driving - Get the Facts

                        MADD - December is National Impaired Driving Prevention Month

                        White House - Proclamation on Impaired Driving Prevention Month, 2020

 

This Safety Tidbit was written by my student, Mr. Lucas Ambler – a senior in the Safety Sciences Program at the Indiana University of PA graduating Summer 2021.

 

In the United States, one person is tragically killed every 50 minutes in a drunk driving accident. In 2016 alone, 10,497 people died in alcohol-impaired driving crashes, which accounted for 28% of all traffic-related deaths in the United States. On November 30th, 2020, The President declared December as National Impaired Driving Prevention Month. The proclamation's mission was to bring awareness to the problem and remember the lives taken due to driving under the influence of alcohol or drugs.

 

Alcohol, drugs, or other medications can impair judgment, perception, coordination, and slow reaction time to a point where the act of operating a motor vehicle is entirely unsafe. The deaths and accidents caused by driving impaired are 100% preventable. However, it takes more than just one person to prevent impaired driving from happening; it requires everyone taking on the personal responsibility of making smart decisions and planning a safe ride home. There are numerous safety precautions an individual can take to avoid impaired driving:

• Before drinking, designate a non-drinking driver when with a group.
• Don't let your friends drive while impaired.
• If you have been drinking, get a ride home, or use a ride share service such as Uber or Lyft.
• If you are hosting a party, remind your guests to plan and designate a sober driver.

 

Whereas this list may seem like common sense, common sense can be blurred and disappear once under the influence. Preparation not only saves your life, but it can save the lives of innocent families put at risk the second that impaired individual gets behind the wheel.

 

December is that time of the year where companies have annual Christmas parties that may involve alcohol. These parties are a great way to socialize and celebrate a year of hard work with colleagues. Ultimately, every person's responsibility is to make safe decisions, find a ride, or even designate themselves to give rides to other coworkers. By committing to following safe practices and avoiding driving impaired, we can prevent many tragedies. The holidays are a wonderful time of the year to celebrate, but in doing so, be safe, be smart, and be proactive in preventing impaired driving.

Safety Tidbit 6.02 – Well the Weather Outside is Frightful -- Please Bundle Up!

 

Safety Tidbit 6.02 – Well  the Weather Outside is Frightful -- Please Bundle Up!

 

Reference: NIOSH - Preventing Cold related Illness, Injury and Death Among Workers

 

This Safety Tidbit was written by my student, Ms. Emma Nippes – a senior in the Safety Sciences Program at the Indiana University of PA graduating Summer 2021.

 

As the winter season quickly approaches, employees begin to face hazards associated with the cold weather. The colder environment can force employees' muscles to work harder and struggle to maintain their internal temperature. This environment is also an ideal situation for employees to develop frostbite, trench foot, and hypothermia while on the job. It is vital to understand the signs and symptoms of these hazards before an employee can become injured.

 

The most severe hazard commonly associated with cold-weather environments is frostbite. Frostbite is an injury to the body caused by freezing temperatures and can affect the frostbitten area's feeling or color. The most prevalent body parts affected include the ears, nose, cheeks, fingers, and toes. If frostbite is left untreated, it can cause permanent damage, and in severe cases, amputation.

 

The next hazard associated with cold weather is trench foot, also known as immersion foot. This issue can occur when temperatures reach as high as 60 degrees Fahrenheit, in addition to an employee's feet continually being wet. And because wet feet lose heat 25 times faster than dry feet, blood vessels begin to constrict and cut off circulation within the feet. The lack of circulation can then cause the skin tissue to die and lead to possible amputation of one or both feet.

 

The final hazard cold-weather hazard is hypothermia. Employees can face the effects of hypothermia when exposed to cold or cool temperatures for a prolonged time. This prolonged exposure can cause the body to lose heat faster than the person can produce it. The consequences of hypothermia include abnormally low body temperature, confusion, and difficulty moving. If left untreated, employees can go into respiratory failure and potentially die.

 

To prevent hazards that come with cold weather, SHE professionals can use some simple work practices. First, ensuring employees are wearing multiple clothing layers and no exposed skin (use of hats that cover the ears and gloves). Waterproof shoes to keep feet dry when working in the snow and ice. These work practices may also include limiting employee exposure to the cold and taking breaks in warm areas when needed. Overall, working in cold weather environments can be dangerous when not adequately prepared for it.

This Safety Tidbit was written by my student, Ms. Elaina Somogyi – a senior in the Safety Sciences Program at the Indiana University of PA graduating Summer 2021.

 

Safety, Health, and Environmental (SHE) professionals analyze leading and lagging indicators to improve workplace safety. To create a safe environment, SHE professionals must be able to identify leading and lagging indicators. SHE professionals must know how to find them, their benefits, and how to use them. Then, the SHE professional will use the data to encourage the employee's safety in the workplace.

 

First, SHE professionals must know what leading and lagging indicators are. According to OSHA, leading indicators are proactive, preventive, and predictive measures that provide information about your safety and health activities' adequate performance. They are used to measure events leading up to injuries, illnesses, and incidents to predict potential workplace problems before they happen. Leading indicators help create change in the workplace. SHE professionals can address the leading indicators in meetings and provide employees with training on preventing the incidents from occurring. By doing so, the SHE professional can decrease the number of injuries in the workplace and save the company money.

 

Lagging indicators measure the occurrence and frequency of events that have occurred in the past. The lagging indicator can include the number of incidents in the workplace. Lagging indicators can alert the SHE professional when there is a failure in a section of its health and safety program. Also, lagging indicators measure the effectiveness of a safety and health system. As a SHE professional, lagging indicators determine the focus areas for workplace health and safety improvement.

 

A SHE professional can use the SMART principles to determine if there are good leading indicators to use. SMART stands for Specific, Measurable, Accountable, Reasonable, and Timely:

• Specific- Does your leading indicator provide specifics for the action taken to minimize risk from a hazard or improve a program area?
• Measurable- Is your leading indicator presented as a number, rate, or percentage that allows you to track and evaluate clear trends over time?
• Accountable- Does your leading indicator track an item that is relevant to your goal?
• Reasonable- Can you reasonably achieve the goal that you set for your leading indicator?
• Timely- Are you tracking your leading indicator regularly enough to spot meaningful trends from your data within your desired timeframe?

 

SHE professional can have workers attend monthly safety meetings. During the meetings, the SHE professional can address the lagging indicators, which are the work areas that need to be improved to ensure a safe workplace. Subsequently, members use the leading indicators during the meetings.

Safety Tidbit 5.14 - Wildlife - An Occupational Hazard

Safety Tidbit 5.14 –Wildlife - An Occupational Hazard

Reference: https://www.safetytalkideas.com/safetytalks/wildlife-in-the-workplace/

This Safety Tidbit was written by my student, Mr. Drew Furman – a senior in the Safety Sciences Program at Indiana University of PA graduating Summer 2020.

Among the many hazards in the workplace, wildlife often is not considered. There are multiple species of wildlife that can pose a threat to humans, all of which are unique. Depending on the location of your workplace. As with most occupational hazards, preparation through anticipation and recognition of potentially dangerous animals is vital. However, knowing how to control or respond if an encounter does occur is equally important.

The hazard of wildlife does not only include attacks and stings but the distractions from work they can cause. Animals on site can deter the focus of the task at hand and allow room for error. Depending on the task being done, any distractions such as swatting at a fly or looking at a deer could provide an opening for an accident.

Preparing for an encounter can almost eliminate the hazard before it has a chance to occur. If working in an area with insects, bug repellent, such as DEET should always be applied. Long clothing that covers the worker's arms and legs should be worn providing a barrier to prevent bites and stings. If the job site is in an area with predators, discouraging an animal encounter may be best. Workers must not approach animals and prohibited from feeding wildlife. If a worker spots an animal, the correct action would be to make noise by yelling or clapping ensuring the animal knows the worker is there and can avoid the worker.

In the event a worker is harmed on-site by an animal or insect, they must notify a supervisor or safety professional. Even something as small as a bee sting is important so the hazard can be investigated before another worker is harmed. It is impractical to prevent all wildlife encounters however, knowing beforehand what to do during and after the encounter can save time and prevent possible injuries.

Safety Tidbit 5.13 - Get Ready for Heat

Safety Tidbit 5.13 – Get Ready for Heat

Reference: https://www.webmd.com/fitness-exercise/heat-exhaustion#1

This Safety Tidbit was written by my student, Mr. Ryan Binkley – a senior in the Safety Sciences Program at Indiana University of PA graduating Summer 2020.

With summer approaching, the weather changes and the temperature heats up bringing with it major concerns to the workplace. As SHE professionals, we know the signs and warn our workers of the signs of heat stress and fatigue in the workplace. If we, as SHE professionals, see the symptoms early, we can help prevent heat stress injuries in the workplace.

Starting off, a good plan is to get to know your workers well before any heat emergency happens. Learn how they generally act or work on a daily basis so you can see subtle changes when something is not quite right. Walking around and talking to employees is a good way to tell if a worker is fatigued or if heat is affecting them. Some signs of heat stress are confusion, dizziness, fainting, headaches, and cramps. If anyone experiences any of these symptoms, they should immediately find shade and drink fluids with electrolytes such as Gatorade, Powerade.

A good way to prevent heat illnesses from occurring is to set up hydration stations around the job site. Have coolers with water bottles readily available along with Gatorade powder they can put in the water if wanted. Alternatively, some companies bring in cooling fans or set up some kind of pavilion/ tent for their employees to sit under during their breaks to cool off. One last thing, although not typical, but that I personally have seen on a construction site is a urine color meter. While employees are using the restroom, they can compare the color of their urine to a table to see if they are dehydrated or not. The final way to reduce heat stress injuries is to enforce breaks for the employees. A lot of employees don’t take their breaks other than lunch, so encourage your employees to take their breaks to allow their bodies to cool down.

Overall, heat stress injuries have the potential to be deadly if not taken care of early. It’s not a guarantee that these suggestions will prevent any injuries, but they will help.

Safety Tidbit 5.12 - Construction's Fatal Four

Safety Tidbit 5.12 – Construction’s Fatal Four

Reference: https://www.osha.gov/data/commonstats

This Safety Tidbit was written by my student, Ms. Paige Graham – a senior in the Safety Sciences Program at Indiana University of PA graduating Summer 2020.

OSHA's data and statistics continue to share the number of fatalities each year in all occupational settings. Out of the 1000 employees that were killed in The United States in construction in 2018, the Fatal Four, as they are known, are responsible for 591 of the deaths, totaling 1 of every 5 workers in construction are killed by one of the fatal four categories. Every year, construction continues to make up more than 20% of fatality rates in all industries. OSHA labeled Falls, Electrocution, Struck By, and Caught-In/Between as the “Fatal Four of Construction.” These hazards are responsible for almost 60% of the fatalities in construction, alone. Out of the 10 most cited OSHA standards, seven of them apply to the Fatal Four. 

By far the leader of the “Fatal Four” are falls making up 33.5 % of all fatalities in construction. Falls include tripping, falling off buildings, scaffolds, or ladders, slipping on any wet or oily substances, and more. The Fall Protection standard, the scaffold standard, and ladder standard are three of the 10 most cited standards. 

Struck-By fatalities consist of a person being hit by a powered vehicle, flying debris during a task, or from objects falling on the job site. Eleven percent (11%) of fatalities in construction fall under this Fatal Four category. 

Electrocution in construction is responsible for about 8.5 % of the fatalities and are mostly due to improperly de-energizing equipment and working on energized overhead power lines. 

Caught-in/Between include the remaining 5.5% of the fatalities in the Fatal Four. These fatalities occurred when the employee was compressed by equipment or crushed/caught in collapsed material. 

OSHA provides many useful tips and recommendations on how to prevent injuries from the Fatal Four in construction, as well as other industries. They also encourage others to help decrease the number of fatalities in construction. Although fatalities in all occupations have decreased through the years, there are still many employees losing their lives to workplace accidents that are senseless and preventable.

Safety Tidbit 5.11 - Hierarchy of Control

Safety Tidbit 5.11 – Hierarchy of Control

Reference: https://www.osha.gov/SLTC/ergonomics/controlhazards.html

This Safety Tidbit was written by my student, Mr. Carey Okoth – a senior in the Safety Sciences Program at the Indiana University of PA graduating Summer 2020.

A fundamental and globally used method of protecting employees from exposures to occupational hazards has been controlling exposures. A hierarchy of controls have been used throughout the years to determine how to use effective control solutions. Hierarchy of controls is a prevention through design kind of model which means that it includes prevention consideration in all designs that impact workers. Elimination, substitution, engineering controls, administrative controls and PPE are what makes up the hierarchy of controls. Elimination is the most effective type of control since it gets rid of the exposure/hazard while PPE is the least effective.

Elimination and substitution are the most effective at reducing hazards but are the most difficult and very costly to implement in an already existing and working process. Elimination and substitution might be simple to implement or less costly if the design is still at the early phases(development stage). Engineering controls are next in line right after elimination and substitution controls. Engineering controls mainly remove the hazard from the source before it comes into contact with the employee. Well-designed engineering controls can be highly effective in protecting workers and will be independent of worker interactions hence enhancing this level of control protection. The initial cost of installing engineering controls might be higher than PPE and administrative controls but in the long run, the operating costs tend to be lower and save the company money in different processes.

Administrative controls and PPE are the last processes in the hierarchy of controls. These controls are usually used with existing processes where hazards cannot be eliminated or engineered. Administrative controls and PPE are not expensive to install but very costly to maintain.  These controls require a lot of effort and cooperation by the employees who are using the control in order for the controls to work effectively.

Safety Tidbit 5.10 – Sobering Safety

Reference: https://www.worksafe.qld.gov.au/__data/assets/pdf_file/0004/82705/understanding-safetyculture.pdf

This Safety Tidbit was written by my student, Ms. Veronica Heithaus – a senior in the Safety Sciences Program at the Indiana University of PA graduating Summer 2020.

Workers expect their employers to offer them a safe environment in which they can work. Research has shown that some workplaces are safer than others. Furthermore, it is a priority, for employers to care about their workers.

To provide workers with a safe and healthy workplace, employers must focus on safety that starts with management and leadership. Management and leadership ensure that work is carried out safely and effectively through the implementation of, safety policies, plans, programs, processes, procedures, and practices. Additionally, safety inspections offer workplaces; safety goals, safety education and, training, as well as, communications are vital.

Not surprisingly, workplace safety oftentimes encourages a sense of loyalty and devotion between the workers and the employer due to the safety promise of the management and leadership teams. The morale and drive of the workers increase when rules that defend their health are provided. Ultimately, they feel safe in the workplace, and therefore, can perform at their best.

Workplace safety is important because it prevents injuries and preserves the lives of the workers. A safe workplace is a place where the risks of injuries or property damage are low. Ultimately, workplace safety is a management/ leadership responsibility. Businesses that have implemented effective health and safety programs desire safer workplaces, but also, they achieve several other things:

1.     lower costs,

2.     improved employee relations and even higher trust

3.     improved efficiency and customer relations.

It is particularly important that all employers provide safe and healthy conditions in which their employees can work effectively without little risk to health. Also, employers and workers should remember that reflection, learning, and experience are the keys to recognizing potential safety hazards in the workplace.

References:                 Fault Tree Analysis https://www.smartdraw.com/fault-tree/

This Safety Tidbit was written by my student, Chris Howell – a senior in the Safety Sciences Program at the Indiana University of PA graduating Spring 2020.

Fault Tree Analysis (FTA) was elaborated by engineers to improve the system safety of missiles. The reasoning for the development of the FTA was because most accidents result from failures inside of a system. There are four parts to a network, including equipment, material, people, and environmental factors. A negative occurrence could result in a near miss. A near miss is an accident that could happen, and that could result in damage to property, equipment, the environment, or personal injury.

There is a connection between the components of a system. If one of the parts fails, the whole system fails. Analytical trees use pictures to represent an event then following deductive reasoning in a top/down approach.

There are six basic symbols for an FTA and described in the table below:

FTA diagrams are not a function of the block or symbols. An FTA diagram is a function of the event. The event is what controls what the shape will be.
