What is Hazard? Types Of Hazards & Control Measures

Every day, we are surrounded by potential hazards. While some may be minor, others can cause severe injury or even death. It is essential for business owners to understand what a hazard is and how to control the risks associated with them. In this blog post, we will discuss what hazard is, the different types of hazards, and the various control measures that can be taken to mitigate those risks.

What is Hazard?

A hazard can be anything that can cause harm or damage to people, property, or the environment. It is important to note that a hazard does not necessarily have to be physical; it can also be chemical, biological, or psychological. Hazardous substances and conditions can exist in both natural and man-made environments.

What is Risk?

Risk is the likelihood that a hazard will cause harm or damage. It is important to note that not all hazards will result in an accident or incident; the level of risk is determined by the severity of the potential harm or damage and the likelihood that it will occur.

Difference Between Hazard and Risk

It is essential to understand the difference between hazard and risk. A hazard is anything that has the potential to cause harm or damage, while a risk is the likelihood that a hazard will actually cause harm or damage. For example, a pool of water is a hazard because it can cause drowning; however, the risk of drowning is determined by the depth of the water, the presence of lifeguards, and the person’s swimming ability.

Hazards Risk Assessment

Hazards risk assessment is identifying, assessing, and controlling hazards. It is a proactive approach to managing health and safety and can be used to identify potential hazards before they occur.

The first step in conducting a hazard risk assessment is identifying the hazards in your workplace. This can be done by observing the work environment and identifying potential hazards. Once the hazards have been identified, they need to be assessed to determine the risks posed by each hazard.

The next step is to control the risks posed by each hazard. This can be done by implementing safety procedures, personal protective equipment, or engineering controls.

Hazard risk assessment is an integral part of managing health and safety in the workplace. By identifying hazards and assessing the risks posed by each hazard, you can control the risks and prevent accidents from happening.

Types Of Hazards At Work

There are four main types of hazards:

• Physical hazards
• Chemical hazards
• Biological hazards
• Psychological hazards

Physical Hazards & Control Measures

Physical hazards refer to the dangers posed by a substance or object due to its physical properties. These hazards can be either visible or invisible or naturally occurring or man-made.

Many different types of physical hazards can be present in the workplace. Some of the most common include:

• Falls: Falls from heights are one of the most common causes of severe injury and death in the workplace. Workers should always use proper safety equipment and follow safe work practices when working at heights.
• Slips, trips, and falls: Slips, trips, and falls are also common causes of injuries in the workplace. Workers should be aware of potential hazards in their work area and take precautions to avoid them.
• Exposure to harmful substances: Workers may be exposed to harmful substances such as chemicals, dust, or fumes while working. Following safe work practices and using proper personal protective equipment is essential to avoid exposure.
• Ergonomic hazards can cause musculoskeletal disorders such as carpal tunnel syndrome or back injuries. Workers should be aware of potential ergonomic hazards in their work environment and take steps to prevent them.
• Noise: Exposure to loud noise can cause hearing loss. Workers should use hearing protection when working in noisy environments.
• Heat and cold: Exposure to extreme temperatures can cause heat or cold stress. Workers should take precautions to avoid exposure to extreme temperatures.

• Electricity: Exposure to electrical hazards can cause shock, burns, or even death. Workers should be aware of potential electrical hazards in their work environment and take steps to avoid them.
• Fire: Fire is one of the most dangerous physical hazards because it can spread quickly and cause extensive damage. If you are in an area where a fire is burning, staying calm and evacuating immediately is essential. Do not try to fight the fire yourself; instead, call 911 and let the professionals handle it.
• Floods: Floods are another major physical hazard that can occur suddenly and without warning. If you live in an area prone to flooding, it is essential to plan how you will evacuate if a flood occurs. Do not try to drive through floodwaters; instead, seek higher ground and wait for help to arrive.
• Earthquakes are another type of physical hazard that can be very dangerous. If you are in an area prone to earthquakes, knowing what to do during one is essential. Drop to the ground, cover your head, and hold on to something sturdy until the shaking stops. Then, evacuate the area immediately and do not re-enter until it has been declared safe by authorities.
• Hurricanes are another type of physical hazard that can cause significant damage. If you live in an area prone to hurricanes, it is important to have a plan for how you will evacuate if one does occur. Do not try to ride out the storm; instead, seek shelter and wait for help to arrive.

Physical hazards are present in many workplaces. It is important for workers to be aware of the potential hazards and take steps to avoid them.

Chemical Hazards & Control Measures

Biological Hazards & Control Measures

Biological hazards can cause harm or damage to people, property, or the environment due to exposure to a biological agent. Examples of biological hazards include but are not limited to:

1. Bacteria

When it comes to the workplace, one of the most common hazards is bacteria. Bacteria are tiny, single-celled organisms that can cause disease. While some bacteria are essential for our health, others can make us sick.

Bacteria can enter our bodies through cuts or open wounds and can also be inhaled through our nose and mouth. Once inside our bodies, bacteria can multiply and cause illness.

Symptoms of bacterial infections vary depending on the type of bacteria but can include fever, diarrhea, vomiting, and abdominal pain. In severe cases, bacterial infections can lead to death.

2. Fungi

Fungi is a type of microorganism that can cause infections in humans. These infections can range from mild to life-threatening. Fungi can be found in many environments, including soil, water, and plants. Some fungi are even capable of causing disease in healthy people.

Fungal infections can be difficult to treat because the fungi can live inside the human body and are not always destroyed by antibiotics. In some cases, surgery may be required to remove the infected tissue. People with weakened immune systems are at a higher risk of developing fungal infections.

If you think you may have a fungal infection, it is essential to see a doctor to get the proper treatment. Fungal infections can be severe and even life-threatening if they are not treated promptly.

3. Viruses

Viruses are tiny infectious particles that can replicate inside the cells of living organisms. Viruses can cause various diseases in humans, from the common cold to more serious illnesses like AIDS. Most viruses are harmless, but some can be deadly. There is no cure for viral infections, but treatments are available for some viruses, such as HIV and influenza.

Viruses are classified into two main groups: DNA viruses and RNA viruses. DNA viruses contain genetic material made of deoxyribonucleic acid (DNA). RNA viruses contain genetic material made of ribonucleic acid (RNA).

4. Protozoa

Protozoa is a serious biological hazard. They are responsible for causing diseases such as malaria, amoebiasis, and giardiasis. Protozoa can also contaminate food and water supplies, leading to gastrointestinal illnesses outbreaks. In some cases, protozoa can even be deadly.

There are a few things that you can do to protect yourself from protozoa. First, make sure that you cook your food properly. Protozoa can often be found in contaminated water, so it’s important to boil or filter your water before drinking it. You should also avoid contact with contaminated soil or water. If you do come into contact with contaminated materials, be sure to wash your hands thoroughly. Finally, if you are traveling to an area where protozoa are common, make sure to take precautions against mosquito bites, as mosquitoes can transmit some types of protozoa.

Following these simple tips can help protect yourself from the dangers of protozoa. Remember, however, that protozoa can be a serious threat, so it’s always best to consult with a healthcare provider if you have any concerns.

5. Parasites

There are many different types of parasites, and they can be found in various environments. Parasites can cause many diseases, some of which can be deadly.

Most people think of parasites as only affecting animals, but this is not always the case. Many parasites can also infect humans, some of which can be quite dangerous.

Knowing about these different types of biological hazards can help you avoid them and protect yourself from potential health risks. You must see a doctor immediately if you think you may have been exposed to any of these hazards.

Psychological Hazards & Control Measures

Psychological hazards are those that can cause harm or damage to people, property, or the environment as a result of exposure to a psychological stressor. Examples of psychological hazards include but are not limited to:

1. Bullying

Bullying in the workplace can lead to many psychological hazards. The first hazard is that it can lead to stress. When you are constantly being bullied, it can take a toll on your mental health and well-being. You may start to feel anxious, depressed, or even suicidal. If you are not careful, bullying can also lead to substance abuse. Bullied people often turn to drugs or alcohol to cope with the pain.

Another psychological hazard of workplace bullying is that it can lead to social isolation. When you are constantly being ridiculed and made to feel inferior, you may start to withdraw from social interactions. You may become scared to speak up or participate in activities because you don’t want to be humiliated. This can lead to loneliness and feeling like you have no one to turn to.

If you or someone you know is being bullied at work, a few things can be done. First, try to talk to the person who is doing the bullying. This can be difficult, but it is important to try to resolve the issue. You can talk to a supervisor or the HR department if that does not work. They can help to investigate the situation and take action if necessary. Finally, you can also seek help from a professional counselor or therapist. They can provide you with support and guidance to help you cope with the situation.

2. Harassment

It is a common scenario at workplaces today. You are sitting in your chair, minding your business, when someone from the other side of the room hurls a lewd comment your way. You are frozen in shock, not knowing how to react. This is just one example of the many ways in which people can be harassed at their workplaces.

While sexual harassment is the most common form of workplace harassment, there are other types as well. These include but are not limited to racial harassment, religious harassment, and disability-based harassment. Workplace harassment can have a severe impact on an individual’s mental health. It can lead to anxiety, depression, and post-traumatic stress disorder (PTSD).

If you are being harassed at work, you must reach out for help. Talk to a trusted friend or family member about what is going on. You can also contact a professional therapist or counselor to help you deal with the psychological effects of workplace harassment. Remember, you are not alone in this. There is help available if you reach out for it.

3. Stress

Stress is the number one psychological hazard in the workplace. It can lead to various problems, including anxiety, depression, gastrointestinal disorders, headaches, heart disease, sleep disorders and stroke.

A number of things can cause stress in the workplace, including long hours, tight deadlines, heavy workloads, job insecurity and conflict with co-workers.

There are several things you can do to manage stress in the workplace. These include:

• Taking breaks during the day
• Eating healthy foods
• Exercising regularly
• Getting enough sleep
• Avoiding caffeine and alcohol
• Practicing relaxation techniques such as yoga or meditation.

If you are feeling overwhelmed by stress, it is important to seek help from a mental health professional. Left untreated, stress can lead to serious problems at work and in your personal life.

4. Violence

Violence can be defined as an act of aggression, whether physical or psychological, that is intended to hurt or kill. It can occur in the workplace, at home, or in public. According to the National Institute for Occupational Safety and Health (NIOSH), violence is a leading cause of death and injury in the workplace. In fact, it is the second leading cause of death for American workers, behind only car accidents.

Many factors can contribute to workplace violence, including job stress, bullying, and exposure to violence in the community. However, one of the most important risk factors is a history of violence or aggression. This includes a history of domestic violence, assault, or other violent crimes.

If you have a history of violence or aggression, getting help from a mental health professional is important before it leads to workplace violence. There are many resources available to help you deal with anger and aggression in a healthy way. With the right support, you can prevent workplace violence before it happens.

Public Health Hazards & Control Measures

Many potential public health hazards can occur when people do not have access to clean water. Waterborne diseases, such as cholera and typhoid fever, are a major concern in areas where water is contaminated. In addition, people who do not have access to clean water are at risk of developing skin infections and other health problems.

One of the most significant public health hazards associated with dirty water is the spread of waterborne diseases. Waterborne diseases are caused by bacteria, viruses, and parasites that can contaminate water supplies. These diseases can cause severe diarrhea, vomiting, and dehydration and can even be fatal. In areas where clean water is unavailable, people are at risk of contracting waterborne diseases if they consume contaminated water or come into contact with it.

Another public health hazard associated with dirty water is the development of skin infections. Skin infections can occur when people come into contact with contaminated water. These infections can cause redness, swelling, and pain and can sometimes lead to serious health problems.

Dirty water can also lead to other health problems, such as respiratory infections and digestive problems. In addition, dirty water can exacerbate existing medical conditions, such as asthma and allergies.

The best way to avoid public health hazards associated with dirty water is to ensure you have access to clean water. If you are unsure about the quality of your water supply, you should contact your local public health department or water utility company. You can also take steps to purify your water at home using a filter or boiling it before drinking it. These simple precautions can help protect yourself and your family from potential public health hazards.

Hierarchy Of Control Measures For Hazards

There are a variety of control measures that can be taken to mitigate the risks associated with hazards. The type of control measure that is most appropriate will depend on the specific hazard involved. Some common control measures include but are not limited to:

• Engineering controls
• Administrative controls
• Personal protective equipment

Engineering Controls

Engineering controls are those that seek to eliminate or minimize exposure to a hazard by altering the work environment. Examples of engineering controls include but are not limited to:

• Local exhaust ventilation
• Machine guards
• Guardrails

Administrative Controls

Administrative controls seek to eliminate or minimize exposure to a hazard by altering how work is done. Examples of administrative controls include but are not limited to:

• Job rotation
• Workplace policies and procedures
• Training programs

Personal Protective Equipment

Personal protective equipment (PPE) is clothing, equipment, or a device that is worn by an individual to protect them from risks in the work environment. Examples of PPE include but are not limited to:

• Hard hats
• Safety glasses
• Earplugs
• Protective clothing

By understanding what hazard is, the different types of hazards, and the various control measures that can be taken to mitigate those risks, you can create a safer workplace for yourself and your employees.

Different Categories Of Hazards

The employer is responsible for identifying hazards. It’s helpful to categorize them into five categories:

• The first three categories (materials, equipment, and the environment) represent hazardous conditions. Hazardous conditions are the surface causes that account for only a tiny percentage of all workplace accidents.
• The fourth category (people) describes employee behaviors. Employee behaviors represent the surface causes that contribute to or cause a higher percentage of workplace accidents.
• The fifth category (system) identifies safety management systems weaknesses. They are the root causes that ultimately contribute to or cause most accidents.

Let’s review these five categories:

Materials: liquids, solids, and gases that can be hazardous to employees.

• Liquid and solid chemicals (such as acids, bases, solvents, explosives, etc.) can produce harmful effects.
• Raw materials (solids like metal, wood, and plastic) used to manufacture products are usually bought in large quantities and can cause injuries or fatalities in many ways.
• Gases, like hydrogen sulfide and methane, may be extremely hazardous if leaked into the atmosphere.

Equipment: machinery and tools used to produce or process goods.

• Hazardous equipment that is improperly guarded and places workers in a danger zone around moving parts could cause injury or death.
• Lack-of preventive and corrective maintenance will make it challenging to ensure equipment operates properly.
• Tools not in good working order, improperly repaired, or not used for their intended purpose is only an accident waiting to happen.

Environment: a general area that employees are working in.

• Poor facility design, hazardous atmospheres, temperature, and/or noise can cause stress.
• If areas in your workplace are too hot, cold, dusty, dirty, messy or wet, then measures should be taken to minimize the adverse conditions.
• Extreme noise that can damage hearing should not be present.
• Workstations may be misdesigned, contributing to an unsafe environment.

People: employees, managers, supervisors, in the workplace.

• Unsafe employee behaviors include taking shortcuts or not using personal protective equipment.
• Employees working while fatigued, under the influence of drugs or alcohol, distracted for any reason, or in a hurry are “walking and working hazards.”

System: Ultimately, the root cause of most accidents is one or more weaknesses within the safety management system.

• Management may unintentionally promote unsafe behaviors. For example, they may ignore non-compliance.
• Inadequate or missing safety plans, programs, policies, processes, procedures, practices, and rules (written and unwritten) may result in injury, illness, or death in the workplace.

Conclusion

Hazards are present in all work environments, but you can create a safer workplace by understanding what they are and how to control them. It is important to always promote a safe culture at your workplace. By doing so, you can help to ensure that everyone remains safe and healthy while they are working. Please contact your local health and safety representative if you have any questions about hazard control or want more information. Thanks for reading!
