![]() ![]() Cost- this is the human factor of the hazard.For example, the Himalayas is extremely vulnerable to earthquakes, but not a tsunami. Vulnerability- this is the weakness of an area towards that particular hazard.For example, the threat of an earthquake in the Himalayas is extremely high. Threat- this is the frequency with which a hazard can hit the area.Scientists have come up with a risk equation to quantify this. The word is often used to quantify the probability of a hazard turning into a disaster. It is the risk that ultimately controls the possibility of converting a hazard into a disaster. Risk, is the likelihood/possibility that an area (or section of population) will be negatively affected by a hazard. Conventionally risk is expressed by the relation Risk = Severity x Likelihood.Now THAT will definitely be a disaster. Risk is the probability of harmful consequences resulting from interactions between threats and vulnerable assets. This could be a malicious hacker or a disgruntled employee. Threat is a party with the intent and capability to exploit vulnerability in an asset. Source: The UN International Strategy for Disaster Reduction (UNISDR, 2006) Risks are always created or exist within social systems, therefore it is important to consider the social contexts in which risks occur and that people therefore do not necessarily share the same perceptions of risk and their underlying causes. Verb in terms of: to expose to chance of injury or loss, venture on, accept the chance of. Risk: (noun) in terms of a hazard, chance, bad consequences, loss, etc. RISK: The probability of harmful consequences, or expected losses (deaths, injuries, property, livelihoods, economic activity disrupted or environment damaged) resulting from interactions between natural or human-induced hazards and vulnerable conditions. Positive factors that increase the ability of people and the society they live in to cope effectively with hazards and can reduce their susceptibility are often designated as capacities. VULNERABILITY: A set of conditions and processes resulting from physical, social, economic, and environmental factors, which increase the susceptibility of a community to the impact of hazards. However all other factors are very rarely equal. If all other factors are equal – especially the exposures and the people subject to them, then the risk is proportional to the hazard. The relationship between hazard and risk must be treated very cautiously. ![]() Disaster = (Hazard x Vulnerability)/ Capacity Disasters may decrease in frequency and severity as capacities are increased. The relationships between hazard, vulnerability and disaster have been commonly represented as:ĭisaster = Hazard + Vulnerability or Disaster= Hazard x Vulnerabilityĭisasters occur when hazard strikes a vulnerable community whose capacity is limited. ![]() Sharp or jagged edges Caught in, on, or between pinch points protruding objects moving/stationary objects Fall to same level to lower level Overexertion lifting pulling pushingĪdverse environmental impact chemicals fire spills rele ases Security unknown/unauthorized people in area missing/damaged materials equipment at work site Hazards: Contact with: electricity chemicals heat or cold ionizing/non-ionizing radiation gases and/or fumes oxygen deficiency Struck by moving or flying objects falling material Strike against stationary or moving objects protruding objects Hazard is the potential to cause harm risk on the other hand is the likelihood of harm (in defined circumstances, and usually qualified by some statement of the severity of the harm).Ī chance of being injured or harmed danger: Space travel is full of hazards.Ī possible source of danger: a fire hazard.
