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. Hazards are sometimes classified into three modes or statuses: The terms "hazard" and " risk " are often used interchangeably.
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 can be defined as the likelihood or probability of a given hazard of a given level causing a particular level of loss of damage. The elements of risk are populations, communities, the built environment , the natural environment , economic activities and services which are under threat of disaster in a given area. Ben Wisner argues that risk or disaster is "a compound function of the natural hazard and the number of people, characterised by their varying degrees of vulnerability to that specific hazard, who occupy the space and time of exposure to the hazard event.
Another definition of risk is "the probable frequency and probable magnitude of future losses". 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. The threats posed by a hazard are:. Hazard symbols or warning symbols are easily recognisable symbols designed to warn about hazardous materials, locations, or objects, The use of hazard symbols is often regulated by law and directed by standards organisations.
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, toxicity classes. 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.

Eliminate the hazard Elimination of the hazard is not always achievable though it does totally remove the hazard and thereby eliminates the risk of exposure.
An example of this would be that petrol station attendants in Ireland are no longer exposed to the risk of chronic lead poisoning following the removal of lead from petrol products sold at forecourts. Substitute the hazard with a lesser risk Substituting the hazard may not remove all of the hazards associated with the process or activity and may introduce different hazards but the overall harm or health effects will be lessened.
The effects can be acute, meaning that the injury or harm can occur or be felt as soon as a person comes in contact with the hazardous agent e. Some responses may be chronic delayed. For example, exposure to poison ivy may cause red swelling on the skin two to six hours after contact with the plant. On the other hand, longer delays are possible: Once the hazard is removed or eliminated, the effects may be reversible or irreversible permanent.
For example, a hazard may cause an injury that can heal completely reversible or result in an untreatable disease irreversible. Add a badge to your website or intranet so your workers can quickly find answers to their health and safety questions.
