Pyrotechnics have been the proximate cause of many accidents and incidents over time, which have resulted in property damage, injury and in severe cases loss of life. These incidents can be the results of poorly manufactured product, unexpected or unforeseen events, or in many cases, operator error.

This page contains a list of incidents involving pyrotechnic substances.

Many pools and designated bathing areas either have lifeguards, a pool safety camera system for local or remote monitoring, or computer-aided drowning detection. However, bystanders play an important role in drowning detection and either intervention or the notification of authorities by phone or alarm.

The acronym "RID" was originated by Frank Pia to summarize important reasons why lifeguards may be unaware of a drowning. The term stands for "failure to recognize the struggle, the intrusion of non-lifeguard duties upon lifeguards' primary task-preventive lifeguarding, and the distraction from surveillance duties". In his paper on the RID factors, Pia makes a number of observations on the role, and the required behavior and training of lifeguards, as well as the importance of administrators directing lifeguards to this role and avoiding double tasking them (due to the very brief time of 20 – 60 seconds required for drowning to occur). He ended by summarizing the role of lifeguards as guardians of life, and that they should be directed exclusively to this duty and none other, while on surveillance, due to the high value placed on human life.

Most drowning is preventable. It has been estimated that more than 85% of drownings could have been prevented by supervision, training in water skills, technology, regulation and public education.

The following is a list of a number of recent incidents characterized as inspired by Islamophobia by commentators.

Note that "Islamophobia" became a popular term in ideological debate in the 2000s, and it may have been applied retrospectively to earlier incidents.

Tetraphobia (from Greek τετράς—"tetras", "four" and φόβος—"phobos", "fear") is the practice of avoiding instances of the number . It is a superstition most common in East Asian nations.

Dancing mania (also known as dancing plague, choreomania, St John's Dance and, historically, St. Vitus's Dance) was a social phenomenon that occurred primarily in mainland Europe between the 14th and 17th centuries. It involved groups of people dancing erratically, sometimes thousands at a time. The mania affected men, women, and children who danced until they collapsed from exhaustion. One of the first major outbreaks was in Aachen, in the Holy Roman Empire, in 1374, and it quickly spread throughout Europe; one particularly notable outbreak occurred in Strasbourg in 1518, also in the Holy Roman Empire.

Affecting thousands of people across several centuries, dancing mania was not an isolated event, and was well documented in contemporary reports. It was nevertheless poorly understood, and remedies were based on guesswork. Generally, musicians accompanied dancers, to help ward off the mania, but this tactic sometimes backfired by encouraging more to join in. There is no consensus among modern-day scholars as to the cause of dancing mania.

The several theories proposed range from religious cults being behind the processions to people dancing to relieve themselves of stress and put the poverty of the period out of their minds. It is, however, thought to have been a mass psychogenic illness in which the occurrence of similar physical symptoms, with no known physical cause, affect a large or small group of people as a form of social influence.

Mass psychogenic illness (MPI), also called mass sociogenic illness or just sociogenic illness, is "the rapid spread of illness signs and symptoms affecting members of a cohesive group, originating from a nervous system disturbance involving excitation, loss, or alteration of function, whereby physical complaints that are exhibited unconsciously have no corresponding organic" cause. MPI is distinct from other collective delusions, also included under the blanket terms of mass hysteria, in that MPI causes symptoms of disease, though there is no organic cause.

There is a clear preponderance of female victims. The DSM-IV-TR does not have specific diagnosis for this condition but the text describing conversion disorder states that "In 'epidemic hysteria', shared symptoms develop in a circumscribed group of people following 'exposure' to a common precipitant."

The "British Medical Journal" reported in a study that looked at mortality statistics in the United States over a

25-year period. They found that on the fourth day of the month, Asian people were thirteen percent more likely to die of heart failure. In California, Asians were twenty-seven percent more likely to die of a heart attack on that day. The purpose of the study was to see if psychological stress caused by belief in this superstition could indeed trigger deadly heart attacks and other fatal incidents.

Below is a list of incidents in Albania that could be considered Islamophobic:

Islamophobia in the United Kingdom refers to a set of discourses, behaviours and structures which express feelings of anxiety, fear, hostility and rejection towards Islam and/or Muslims in the United Kingdom. Islamophobia can manifest itself through discrimination in the workforce, negative coverage in the media, and violence against Muslims.

As of 2017, acid attacks, arson attacks against mosques and vehicle ramming have statistically risen against Muslims, predominately in England and Scotland.

The effect of mercury took some time – the latent period between ingestion and the first symptoms (typically paresthesia – numbness in the extremities) was between 16 and 38 days. Paresthesia was the predominant symptom in less serious cases. Worse cases included ataxia (typically loss of balance), blindness or reduced vision, and death resulting from central nervous system failure. Anywhere between 20 and 40 mg of mercury has been suggested as sufficient for paresthesia (between 0.5 and 0.8 mg/kg of body weight). On average, individuals affected consumed 20 kg or so of bread; the 73,000 tonnes provided would have been sufficient for over 3 million cases.

The hospital in Kirkuk received large numbers of patients with symptoms that doctors recognised from the 1960 outbreak. The first case of alkylmercury poisoning was admitted to hospital on 21 December. By 26 December, the hospital had issued a specific warning to the government. By January 1972, the government had started to strongly warn the populace about eating the grain, although dispatches did not mention the large numbers already ill. The Iraqi Army soon ordered disposal of the grain and eventually declared the death penalty for anyone found selling it. Farmers dumped their supplies wherever possible, and it soon got into the water supply (particularly the River Tigris), causing further problems. The government issued a news blackout and released little information about the outbreak.

The World Health Organization assisted the Iraqi government through the supply of drugs, analytical equipment and expertise. Many new treatments were tried, since existing methods for heavy metal poisoning were not particularly effective. Dimercaprol was administered to several patients, but caused rapid deterioration of their condition. It was ruled out as a treatment for this sort of poisoning following the outbreak. Polythiol resins, penicillamine and dimercaprol sulfonate all helped, but are believed to have been largely insignificant in overall recovery and outcomes. Dialysis was tested on a few patients late in the treatment period, but they showed no clinical improvement. The result of all treatments was varied, with some patients' blood mercury level being dramatically reduced, but a negligible effect in others. All patients received periods of treatment interspersed with lay periods; continuous treatment was suggested in future cases. Later treatment was less effective in reducing blood toxicity.

The majority of blast-related ocular injuries occur in soldiers who present with other life-threatening injuries that require immediate intervention. Current Combat Support Hospital (CSH) protocol requires the surgical stabilization of any life-threatening injuries, as well as hemodynamic stability, prior to initial eye evaluation and surgical repair. Therefore, initiation of emergency ophthalmic care often occurs hours after injury. Initial examination by a military ophthalmologist begins with gross examination of each eye and orbital. 73-82% of all ocular injuries resulting from mine explosions are due to fragmentation of shrapnel upon detonation, so gross anatomical inspection by penlight may not rule out open globe injury.

Ophthalmol Clin North Am. 2002; 15(2):153-61./ref> Computerized tomography (CT) may detect foreign matter and aid the clinician in determining the presence of an open-globe injury.

Anti-Chinese sentiment, Sinophobia (from Late Latin "Sinae" "China" and Greek φόβος, "phobos", "fear"), or Chinophobia is a sentiment against China, its people, overseas Chinese, or Chinese culture. It often targets Chinese minorities living outside of China and is complicated by the dilemma of immigration, development of national identity in neighbouring countries, disparity of wealth, the fall of the past central tribute system and majority-minority relations. Its opposite is Sinophilia. Factors contributing to sinophobia include disapproval of the Chinese government, historical grievances, fear of economic competition, and racism. Sinophobia also stems from older ethnic tensions, such as those related to Japanese nationalism, Korean nationalism, Indian nationalism and Vietnamese nationalism.

Anti-Arabism, Anti-Arab sentiment or Arabophobia is opposition to, or dislike, fear, hatred, and advocacy of genocide of Arab people.

Historically, anti-Arab prejudice has been suggested by such events as the reconquest of the Iberian Peninsula, the condemnation of Arabs in Spain by the Spanish Inquisition, the Zanzibar Revolution in 1964, and the 2005 Cronulla riots in Australia. In the current era, racial prejudice against Arabs is apparent in many countries including Iran, Poland, France, Australia, Israel, and the United States (including Hollywood). Various advocacy organizations have been formed to protect the civil rights of Arab citizens in the United States, such as the American-Arab Anti-Discrimination Committee (ADC) and the Council on American-Islamic Relations (CAIR).

In Scientology, an implant is a form of Thought insertion, similar to an engram but done deliberately and with evil intent. It is "an intentional installation of fixed ideas, contra-survival to the thetan".

The intention in the original engram or incident is to implant an idea or emotion or sensation, regarding some phenomenon etc. The intention in Scientology and Dianetics is to erase the compulsive or command effect of the idea, emotion, sensation, etc. so that the person can make a rational judgment and decision in the affected areas of life.

Scientology practices often have to do with addressing implants prior to the current lifetime — one of the most notable is the "R6 implant"; but in some cases current life implants are addressed. Examples of implants according to Scientology include Aversion therapy, Electroconvulsive therapy, hypnosis, various attempts at brainwashing, and the inducing of fear or terror. Note that this is not a complete list, as many kinds of incidents can include implants as an element.

Other important implants in Scientology doctrine include the Helatrobus implants, which Hubbard claimed occurred 382 trillion years ago to 52 trillion years ago by an alien nation called the Helatrobans, who sought to restrain human minds by capturing and brainwashing thetans. These implants are said to be responsible for the concept of Heaven.

According to Balaratnasingam and Janca, “mass hysteria is to date a poorly understood condition. Little certainty exists regarding its” cause.

Besides the difficulties common to all research involving the social sciences, including a lack of opportunity for controlled experiments, mass sociogenic illness presents special difficulties to researchers in this field. Balaratnasingam and Janca report that the methods for “diagnosis of mass hysteria remains contentious. According to Timothy Jones of the Tennessee Department of Public Health, the effects resulting from MPI “can be difficult to differentiate from [those of] bioterrorism, rapidly spreading infection or acute toxic exposure.”

These troubles result from the residual diagnosis of MPI. Singer, of the Uniformed Schools of Medicine, puts the problems with such a diagnosis thus:

“[y]ou find a group of people getting sick, you investigate, you measure everything you can measure . . . and when you still can't find any physical reason, you say 'well, there's nothing else here, so let's call it a case of MPI.'” There is a lack of logic in an argument that proceeds: “There isn't anything, so it must be MPI.” It precludes the notion that an organic factor could have been overlooked. Nevertheless, running an extensive number of tests extends the probability of false positives.

British psychiatrist Simon Wesseley distinguishes between two forms of MPI:

- mass anxiety hysteria “consists of episodes of acute anxiety, occurring mainly in schoolchildren. Prior tension is absent and the rapid spread is by visual contact.”

- mass motor hysteria “consists of abnormalities in motor behaviour. It occurs in any age group and prior tension is present. Initial cases can be identified and the spread is gradual. . . . [T]he outbreak may be prolonged.”

While his definition is sometimes adhered to, others such as Ali-Gombe et al. of the University of Maiduguri, Nigeria contest Wesseley's definition and describe outbreaks with qualities of both mass motor hysteria and mass anxiety hysteria.

An evolutionary psychology explanation for this disorder, as well as for conversion disorder more generally, is that the symptom may have been evolutionarily advantageous during warfare. A non-combatant with these symptoms signals non-verbally, possibly to someone speaking a different language, that she or he is not dangerous as a combatant and also may be carrying some form of dangerous infectious disease. This can explain that conversion disorder may develop following a threatening situation, that there may be a group effect with many people simultaneously developing similar symptoms, and the gender difference in prevalence.

Islamophobia in Australia is a fear of Islam in Australian society; it has been associated with hostile and discriminatory practices toward Muslim individuals or communities and the exclusion of Muslims from social, cultural and political affairs.

Islamophobia and intolerance towards Muslims has existed well prior to the September 11 attacks on the United States.

Current military standard employs the Birmingham Eye Trauma Terminology System (BETTS) and Ocular Trauma Classification Group to define and treat blast injuries. Trauma is further split into two distinct groups: closed globe injury and open globe trauma. Treatment of closed globe trauma begins with the division of the eye into zones, each with unique anatomical structures and injury patterns:

- Zone I: the conjunctiva and corneal surface; the most common injuries seen in this zone are foreign debris retention by the conjunctiva or corneal epithelium/stroma, as well as corneal abrasions. The Seidel test may be used to evaluate the status of the anterior chamber, thereby determining the presence of corneal perforation and pathological anterior chamber leakage.

- Zone II: region designated by the anterior chamber, lens, and pars plicata; the most common injuries sustained in this region are hyphemas and traumatic cataracts. Application of the Seidel Test in Zone I will rule out seepage of the anterior chamber through a corneal perforation, while introduction of topical agents may reduce detected increases in intraocular pressure. Depending on the severity of other bodily injuries, the military ophthalmologist may conduct an anterior chamber washout to clear hyphemas. However, reconstruction of the anterior chamber and cataract surgery is often reserved for treatment in tertiary clinical centers.

- Zone III: this zone contains the vitreous cavity, retina, and optic nerve; injuries commonly observed in this region are vitreous hemorrhage, traumatic macular holes, retinal detachment, and optic nerve injury. Injury to the optic nerve requires neuro-ophthalmic examination, and may require neurosurgical intervention in the military hospital setting depending on the severity of the injury.

Islamophobia in the media refers to the occurrence or perception that media outlets tend to cover Muslims or Islam-related topics in a negative light. Islamophobia is defined as "Intense dislike or fear of Islam, esp. as a political force; hostility or prejudice towards Muslims".

The need for imaging in patients who have suffered a minor head injury is debated. A non-contrast CT of the head should be performed immediately in all those who have suffered a moderate or severe head injury, an MRI is also an option. Computed tomography (CT) has become the diagnostic modality of choice for head trauma due to its accuracy, reliability, safety, and wide availability. The changes in microcirculation, impaired auto-regulation, cerebral edema, and axonal injury start as soon as head injury occurs and manifest as clinical, biochemical, and radiological changes.

6,530 patients were admitted to hospitals with poisoning, and 459 deaths reported. Cases reached a peak of hundreds per day in January, and had largely subsided by the beginning of March. The last admittance was on 27 March; admissions represented every age and gender stratum, although those under the age of ten represented a third of admitted cases. This number is "certainly an underestimate", because of the availability of hospital treatment, hospital overcrowding and lack of faith in treatment. In the most severely affected areas, prevalence was 28% and mortality was 21% of the cases. Some Iraqi doctors believe both the number of cases and fatalities are at least ten times too low, with perhaps 100,000 cases of brain damage. One suggested reason for the vast discrepancy between reported and estimated numbers of deaths is the Iraqi custom, common to large parts of the Middle East, for a person to die at home when possible. Home deaths would not have been recorded.

A large number of patients with minor symptoms recovered completely; those with more serious symptoms improved. This was in contrast to expected outcomes, largely based on analysis of Minamata disease in Japan. In boys with mercury levels below clinical poisoning, a reduction in school performance was noted, although this correlation could not be confirmed. In infants, the mercury poisoning caused central nervous system damage. Relatively low doses caused slower development in children, and abnormal reflexes. Different treatments for mercury poisoning have since been developed, and "quiet baby syndrome", characterised by a baby who never cries, is now a recognised symptom of methylmercury-induced brain damage. Ongoing recommendations of the food regulation authorities have focused on consumption by pregnant women and infant children, noting the particular susceptibility of fetuses and infants to methylmercury poisoning. Data from Iraq have confirmed that methylmercury can pass to a child "in utero", and mercury levels were equal to or higher in the newborn child than in the mother.

In 1974, a joint Food and Agriculture Organization (FAO) and World Health Organisation (WHO) meeting made several recommendations to prevent a similar outbreak. These included stressing the importance of labelling bags in the local language and with locally understood warning symbols. The possibility of an additive creating a strong bitter taste was studied. The meeting urged governments to strictly regulate methyl- and ethylmercury use in their respective countries, including limiting use to where no other reasonable alternative was available. It also recommended the involvement of the FAO and WHO in assisting national governments in regulation and enforcement, and the setting up of national poison control centres. Over 9–13 November, a Conference on Intoxication due to Alkylmercury-Treated Seed was held in Baghdad. It supported the recommendations of the FAO/WHO report and further suggested that local and national media should publicise outbreaks, including size and symptoms; it considered the distribution of this information crucial. It also laid out a general plan as to the collection of relevant information from the field and potential analysis for further investigation. It called on national governments to make use of WHO involvement whenever feasible, and absolved world governments in clear terms, saying that "No country should ever feel that any blame will attach to it for allowing an outbreak to occur".

Iraq now has the highest incidence of Parkinson's in the world. Parkinson's symptoms are very similar to mercury poisoning symptoms. Mercury that enters the brain has a half-life of 27.5 years and chelators are not able to remove it.

Xenophobia is the fear and distrust of that which is perceived to be foreign or strange. Xenophobia can manifest itself in many ways involving the relations and perceptions of an ingroup towards an outgroup, including a fear of losing identity, suspicion of its activities, aggression, and desire to eliminate its presence to secure a presumed purity. Xenophobia is a political term and not a recognized medical phobia.

Xenophobia can also be exhibited in the form of an "uncritical exaltation of another culture" in which a culture is ascribed "an unreal, stereotyped and exotic quality". The terms xenophobia and racism are sometimes confused and used interchangeably because people who share a national origin may also belong to the same race. Due to this, xenophobia is usually distinguished by opposition to foreign culture.

Video game playing may be associated with vision problems. Extensive viewing of the screen can cause eye strain, as the cornea, pupil, and iris are not intended for mass viewing sessions of electronic devices. Using video games for too long may also cause headaches, dizziness, and chances of vomiting from focusing on a screen.

However, certain studies have shown that video games can be used to improve various eye conditions. An investigation into the effect of action gaming on spatial distribution of attention was conducted and revealed that gamers exhibited an enhancement with attention resources compared to non-gamers, not only in the periphery but also in central vision. Further studies in 2011, concluded that a combination of video game therapy alongside occlusion therapy, would greatly improve the recovery of visual acuity in those experiencing amblyopia.

Video game-related health problems can induce repetitive strain injuries, skin disorders or other health issues. Other problems include video game-provoked seizures in patients with epilepsy. In rare and extreme cases, deaths have resulted from excessive video game playing (see Deaths due to video game addiction).

In a high energy injury to the midfoot, such as a fall from a height or a motor vehicle accident, the diagnosis of a Lisfranc injury should, in theory at least, pose less of a challenge. There will be deformity of the midfoot and X-ray abnormalities should be obvious. Further, the nature of the injury will create heightened clinical suspicion and there may even be disruption of the overlying skin and compromise of the blood supply. Typical X-ray findings would include a gap between the base of the first and second toes. The diagnosis becomes more challenging in the case of low energy incidents, such as might occur with a twisting injury on the racquetball court, or when an American Football lineman is forced back upon a foot that is already in a fully plantar flexed position. Then, there may only be complaint of inability to bear weight and some mild swelling of the forefoot or midfoot. Bruising of the arch has been described as diagnostic in these circumstances but may well be absent. Typically, conventional radiography of the foot is utilized with standard non-weight bearing views, supplemented by weight bearing views which may demonstrate widening of the interval between the first and second toes, if the initial views fail to show abnormality. Unfortunately, radiographs in such circumstances have a sensitivity of 50% when non-weight bearing and 85% when weight bearing, meaning that they will appear normal in 15% of cases where a Lisfranc injury actually exists. In the case of apparently normal x-rays, if clinical suspicion remains, advanced imaging such as magnetic resonance imaging (MRI) or X-ray computed tomography (CT) is a logical next step.
