For other uses, see. A hazard is an agent which has the potential to cause harm to a vulnerable target. However, in terms of risk assessment, they are two very distinct terms. A hazard is any agent that can cause harm or damage to humans, property, or the environment. Risk is defined as the probability that exposure to a hazard will lead to a negative consequence, or more simply, a hazard poses no risk if there is no exposure to that hazard. Hazards can be dormant or potential, with only a theoretical probability of harm. An event that is caused by interaction with a hazard is called an. The likely severity of the undesirable consequences of an incident associated with a hazard, combined with the of this occurring, constitute the associated. If there is no possibility of a hazard contributing towards an incident, there is no risk. Hazards can be classified as different types in several ways. One of these ways is by specifying the origin of the hazard. One key concept in identifying a hazard is the presence of stored energy that, when released, can cause damage. Stored energy can occur in many forms: chemical, mechanical, thermal, radioactive, electrical, etc. Another class of hazard does not involve release of stored energy, rather it involves the presence of hazardous situations. Examples include confined or limited egress spaces, oxygen-depleted atmospheres, awkward positions, repetitive motions, low-hanging or protruding objects, etc. Hazards may also be classified as natural, , or. They may also be classified as health or safety hazards, by the populations that may be affected, and the severity of the associated risk. In most cases a hazard may affect a range of targets, and have little or no effect on others. Identification of hazards assumes that the potential targets are defined, and is the first step in performing a. Hazards may be grouped according to their characteristics. Technological and man made hazards include explosions, release of toxic materials, episodes of severe , structural collapses, and transportation, construction and manufacturing etc. A distinction can also be made between rapid onset natural hazards, technological hazards and social hazards which are described as being of sudden occurrence and relatively short duration, and the consequences of longer term environmental degradation such as desertification and drought,. In this sense the environmental conditions we may consider hostile or hazardous can be seen as neutral in that it is our perception, human location and actions which identify resources and hazards within the range of natural events. Smith states that natural hazards are best seen in an ecological framework in order to distinguish between natural events as natural hazards. Firstly through location, because it is only when people and their possessions get in the way of natural processes that hazard exists. In this context we can see that there may be an acceptable variation of magnitude which can vary from the estimated normal or average range with upper and lower limits or thresholds. In these extremes the natural occurrence may become an event that presents risk to the environment or people. As long as the variation of the environmental element remains fairly close to this expected performance, insignificant damage occurs and the element will be perceived as beneficial. However when the variability exceeds some threshold beyond the normal band of tolerance, the same variable starts to impose a stress on society and become a hazard. Hazards can be classified as different types in several ways. One of these ways is by specifying the origin of the hazard. One key concept in identifying a hazard is the presence of stored energy that, when released, can cause damage. Stored energy can occur in many forms: chemical, mechanical, thermal, radioactive, electrical, etc. Another class of hazard does not involve release of stored energy, rather it involves the presence of hazardous situations. Examples include confined or limited egress spaces, oxygen-depleted atmospheres, awkward positions, repetitive motions, low-hanging or protruding objects, etc. Hazards may also be classified as , , or. They may also be classified as or hazards and by the populations that may be affected, and the severity of the associated risk. In most cases a hazard may affect a range of targets, and have little or no effect on others. Identification of hazards assumes that the potential targets are defined. Based on energy source Biological hazard Main article: Biological hazards, also known as biohazards, originate in processes of living organisms, and refer to agents that pose a threat to the health of , the security of property, or the health of the environment. The term and may be used as a warning, so that those potentially exposed to the substances will know to take precautions. The biohazard symbol was developed in 1966 by Charles Baldwin, an environmental-health engineer working for the on the containment products. Biological hazards include viruses, parasites, bacteria, food, fungi, and foreign toxins. Many specific biological hazards have been identified. For example, the hazards of naturally-occurring bacteria such as and , are well known as disease-causing pathogens and a variety of measures have been taken to limit human exposure to these through food safety, good personal hygiene and education. However, the potential for new biological hazards exists through the discovery of new microorganisms and through the development of new genetically modified GM organisms. Use of new GM organisms is regulated by various governmental agencies. The US EPA controls GM plants that produce or resist pesticides i. The US FDA regulates GM plants that will be used as food or for medicinal purposes. Biological hazards can include medical waste or samples of a , or from a biological source that can affect. Many biological hazards are associated with food, including certain , , , , and plant and seafood. Pathogenic and are common foodborne biological hazards. The hazards from these bacteria can be avoided through risk mitigation steps such as proper handling, , and of food. Disease in humans can come from biological hazards in the form of infection by bacteria, antigens, viruses, or parasites. Chemical hazard See also: A chemical can be considered a hazard if by virtue of its intrinsic properties it can cause harm or danger to humans, property, or the environment. Health hazards associated with chemicals are dependent on the dose or amount of the chemical. For example, iodine in the form of potassium iodate is used to produce. When applied at a rate of 20 mg of potassium iodate per 1000 mg of table salt, the chemical is beneficial in preventing , while intakes of 1200—9500 mg in one dose have been known to cause death. Some chemicals have a cumulative biological effect, while others are metabolically eliminated over time. Other chemical hazards may depend on concentration or total quantity for their effects. A variety of e. However, every year companies produce more new chemicals to fill new needs or to take the place of older, less effective chemicals. Laws, such as the and the in the US, require protection of human health and the environment for any new chemical introduced. In the US, the EPA regulates new chemicals that may have environmental impacts i. The potential hazards of these chemicals can be identified by performing a variety of tests prior to the authorization of usage. The number of tests required and the extent to which the chemicals are tested varies, depending on the desired usage of the chemical. Chemicals designed as new drugs must undergo more rigorous tests that those used as pesticides. Some harmful chemicals occur naturally in certain geological formations, such as or. Other chemicals include products with commercial uses, such as agricultural and industrial chemicals, as well as products developed for home use. Pesticides, which are normally used to control unwanted insects and plants, may cause a variety of negative effects on non-target organisms. The organochlorine pesticide has been linked to. Corrosive chemicals like , which is found in car batteries and research laboratories, can cause severe skin burns. Many other chemicals used in industrial and laboratory settings can cause respiratory, digestive, or problems if they are inhaled, ingested, or absorbed through the skin. The negative effects of other chemicals, such as and , have been well documented. Ergonomic hazards occur in both occupational and non-occupational settings such as in workshops, building sites, offices, home, school, or public spaces and facilities. Mechanical hazard Further information: and A mechanical hazard is any hazard involving a machine or industrial process. Motor vehicles, aircraft, and pose mechanical hazards. These hazard identification studies focus mainly on deviations from the intended use or design and the harm that may occur as a result of these deviations. These studies are regulated by various agencies such as the and the. Physical hazard Main article: A physical hazard is a naturally occurring process that has the potential to create loss or damage. Physical hazards include , , , and. Physical hazards often have both human and natural elements. Flood problems can be affected by the natural elements of climate fluctuations and storm frequency, and by land drainage and building in a , human elements. Another physical hazard, , naturally occur from , but have also been utilized by humans for medical purposes; however, can lead to , , and. Psychosocial hazard Main article: Psychological or psychosocial hazards are hazards that affect the psychological well-being of people, including their ability to participate in a work environment among other people. Linked to psychosocial risks are issues such as occupational stress and workplace violence which are recognized internationally as major challenges to occupational health and safety. According to the , each year 130,000 people are killed, 90,000 are injured and 140 million are affected by unique events known as natural disasters. Recent policy-oriented work into hazard management began with the work of Gilbert White, the first person to study engineering schemes as a means of mitigating flooding in the US. From 1935 to 1967 White and his colleagues led the research into flood defences, and further collaboration on investigation was undertaken at the University of Chicago. Anthropogenic hazards Main article: Any single or combination of toxic chemical, biological, or physical agents in the environment, resulting from human activities or natural processes, that may impact the health of exposed subjects, including pollutants such as heavy metals, pesticides, biological contaminants, toxic waste, industrial and home chemicals. Based on effects Health hazards Hazards affecting the health of exposed persons, usually having an acute or chronic illness as the consequence. Fatality would not normally be an immediate consequence. Health hazards may cause measurable changes in the body which are generally indicated by the development of signs and symptoms in the exposed persons, or non-measurable, subjective symptoms. Safety hazards Hazards affecting the safety of individuals, usually having an injury or immediate fatality as the consequence of an incident Economic hazards Hazards affecting property, wealth and the economy. Environmental hazards See also: can be defined as a serious disruption, occurring over a relatively short time, of the functioning of a community or a society involving widespread human, material, economic, societal or and impacts, which exceeds the ability of the affected community or society to cope using its own resources. Disaster can manifest in various forms, threatening those people or environments specifically vulnerable. Such impacts include loss of property, death, injury, trauma or. Disaster can take various forms, including hurricane, , tsunami, earthquake, , , , disease, , , , , flooding, toxic release, and spills ,. These can affect people and the environment on the local regional level, national level or international level Wisner et al. A disaster hazard is an extreme geophysical event that is capable of causing a disaster. The fundamental determinants of hazard and the risk of such hazards occurring is timing, location, magnitude and frequency. For example, magnitudes of earthquakes are measured on the Richter scale from 1 to 10, whereby each increment of 1 indicates a tenfold increase in severity. The magnitude-frequency rule states that over a significant period of time many small events and a few large ones will occur. Hurricanes and typhoons on the other hand occur between 5 degrees and 25 degrees north and south of the equator, tending to be seasonal phenomena which are thus largely recurrent in time and predictable in location due to the specific climate variables necessary for their formation. This definition includes indirect losses of life caused after initial onset of the disaster such as secondary effects of, e. As with other definitions of disaster, this definition not only encompasses social aspect of disaster impact and stresses potentially caused but also focuses on losses, implying the need for an emergency response as an aspect of disaster. It does not however set out quantitative thresholds or scales for damage, death or injury respectively. For instance, a hillside may be unstable, with the potential for a , but there is nothing below or on the hillside that could be affected. However, in terms of risk assessment, these are two very distinct terms. A hazard is an agent that can cause harm or damage to humans, property, or the environment. Risk is the probability that exposure to a hazard will lead to a negative consequence, or more simply, a hazard poses no risk if there is no exposure to that hazard. The elements of risk are populations, communities, the , the , economic activities and services which are under threat of in a given area. This definition also focuses on the probability of future loss whereby degree of vulnerability to hazard represents the level of risk on a particular population or environment. Hazard symbols or warning symbols are easily recognisable designed to warn about hazardous materials, locations, or objects, The use of hazard symbols is often regulated by law and directed by. Hazard symbols may appear with different colors, backgrounds, borders and supplemental information in order to specify the type of hazard and the level of threat for example,. Warning symbols are used in many places in lieu of or addition to written warnings as they are quickly recognized faster than reading a written warning and more universally understood, as the same symbol can be recognized as having the same meaning to speakers of different languages.
