Harmful substance, a condition or an event
Environmental hazards are those hazards that affect biomes or ecosystems. Well known examples include oil spills, water pollution, slash and burn deforestation, air pollution, ground fissures, and build up of atmospheric carbon dioxide. Physical exposure to environmental hazards is usually involuntary
Biological hazards, also known as biohazards, are organic substances that pose a threat to the health of living organisms, primarily humans. This can include medical waste, samples of a microorganism, virus, or toxin (from a biological source) that can impact human health. Biological hazards can also include substances harmful to animals. Examples of biological hazards include bacteria, viruses, fungi, other microorganisms and their associated toxins. They may cause a myriad of diseases, from flu to more serious and potentially fatal diseases. Hazard identification is the determination of whether, and under what conditions, a given environmental stressor has the potential to cause harm. In hazard identification, sources of data on the risks associated with prospective hazards are identified. For instance, if a site is known to be contaminated with a variety of industrial pollutants, hazard identification will determine which of these chemicals could result in adverse human health effects, and what effects they could cause. Risk assessors rely on both laboratory (e. g., toxicological) and epidemiological data to make these determinations. Conceptual model of exposure
Hazards have the potential to cause adverse effects only if they come into contact with populations that may be harmed. For this reason, hazard identification includes the development of a conceptual model of exposure. Conceptual models communicate the pathway connecting sources of a given hazard to the potentially exposed population(s). The U. S. Agency for Toxic Substances and Disease Registry establishes five elements that should be included in a conceptual model of exposure:
The source of the hazard in question
Environmental fate and transport, or how the hazard moves and changes in the environment after its release
Exposure point or area, or the place at which an exposed person comes into contact with the hazard
Exposure route, or the manner by which an exposed person comes into contact with the hazard (e. g., orally, dermally, or by inhalation)
Potentially exposed populations. These measurements should be compared to appropriate reference levels to determine whether a hazard exists. For instance, if arsenic is detected in tap water from a given well, the detected concentrations should be compared with regulatory thresholds for allowable levels of arsenic in drinking water. If the detected levels are consistently lower than these limits, arsenic may not be a chemical of potential concern for the purposes of this risk assessment. When interpreting hazard data, risk assessors must consider the sensitivity of the instrument and method used to take these measurements, including any relevant detection limits (i. e., the lowest level of a given substance that an instrument or method is capable of detecting).

Қоршаған ортаның қауіптері – биомдарға немесе экожүйелерге әсер ететін қауіптер. Белгілі мысалдарға мұнайдың төгілуі, судың ластануы, орманды кесіп өртеу, ауаның ластануы, жердің жарылуы және атмосферадағы көмірқышқыл газының жиналуы жатады. Қоршаған ортаның қауіптеріне физикалық әсер ету көбінесе еріксіз болады.

Биологиялық қауіптер, сондай-ақ биоқауіптер деп те аталады, тірі организмдердің, ең алдымен адамның денсаулығына қауіп төндіретін органикалық заттар болып табылады. Бұл медициналық қалдықтар, микроорганизмдердің, вирустардың немесе токсиндердің (биологиялық көзден) сынамалары болуы мүмкін, олар адам денсаулығына әсер етуі мүмкін. Биологиялық қауіптерге жануарларға зиянды заттар да жатады. Биологиялық қауіптерге бактериялар, вирустар, саңырауқұлақтар, басқа микроорганизмдер және олармен байланысты токсиндер кіреді. Олар грипптен бастап, одан да қауіпті және өлімге әкелетін ауруларға дейін көптеген ауруларды тудыруы мүмкін. Қауіпті анықтау – қоршаған ортаның белгілі бір стрессорларының зиян келтіру әлеуеті бар-жоғын және қандай жағдайда екенін анықтау. Қауіпті анықтау кезінде ықтимал қауіптермен байланысты тәуекелдер туралы деректердің көздері анықталады. Мысалы, егер бір орынның әртүрлі өнеркәсіптік ластаушы заттармен ластанғаны белгілі болса, қауіпті анықтау осы химиялық заттардың қайсысы адам денсаулығына зиян тигізуі мүмкін екенін және қандай әсерлерге алып келуі мүмкін екенін анықтайды. Тәуекелді бағалаушылар осы анықтамаларды жасау үшін зертханалық (мысалы, токсикологиялық) және эпидемиологиялық деректерге сүйенеді.

Психологиялық
Психологиялық қауіптер стресс, зорлық-зомбылық және жұмыс орнындағы басқа да күйзеліс тудыратын факторларды қамтиды, бірақ олармен шектелмейді. Жұмыс көбінесе психикалық денсаулыққа және жеке өмірге оң әсер етеді. Ол адамдарға белгілі бір рет пен мақсатты ұсынады, сондай-ақ өзіндік сананы қалыптастыруға көмектеседі.
Psychological hazards include but are not limited to stress, violence and other workplace stressors. Work is generally beneficial to mental health and personal wellbeing. It provides people with structure and purpose and a sense of identity.
