Hazard and risk

One of these ways is by specifying the origin of the hazard. However, the potential for new biological hazards exists through the discovery of new microorganisms and through the development of new genetically modified GM organisms. Traffic accident and Road safety A mechanical hazard is any hazard involving a machine or industrial process.

Key Differences Between Risk and Hazard The following points are substantial so far as the difference between risk and hazard is concerned: It is the agent; that poses a threat to people, property, environment, etc.

What is an adverse health effect? Any substance, activity, process, equipment which is having ability to induce, Injury to the persons Damage to the environment should be considered as a hazard. In Hazard and risk extremes the natural occurrence may become an event that presents risk to the environment or people.

Biological hazards can include medical waste or samples of a microorganismvirus or toxin from a biological source that can affect health. Two risk factors could be slotted in the same category if one tripled the risk of cancer and the other increased it by a small fraction.

In short, it is the set of conditions, which when combined with other conditions of the environment, can result in loss, damage, liability or any other negative consequence. Some harmful chemicals occur naturally in certain geological formations, such as radon gas or arsenic.

Based on energy source[ edit ] Biological hazard Main article: The social, natural and built environment are not only at risk from geophysical hazards, but also from technological hazards including industrial explosionsrelease of chemical hazards and major accident hazards MAHs.

Hazard and Risk

This is a critical distinction. What is a risk assessment? These hazard identification studies focus mainly on deviations from the intended use or design and the harm that Hazard and risk occur as a result of these deviations. A variety of chemical hazards e.

Ergonomic hazard Main article: On the other hand, hazard only results in adverse effects. Firstly through location, because it is only when people and their possessions get in the way of natural processes that hazard exists. Physical object, situation or setting Expression It can be expressed in degrees.

The difference may sound like an unimportant jargon-filled distinction, but this difference is critical to understanding reports of hazards and risks. They could also be classified similarly even if one causes many more types of cancers than the other, if it affects a greater swath of the population, and if it actually causes more cancers.

They may also be classified as health or safety hazards and by the populations that may be affected, and the severity of the associated risk. Areal extent of damage zone [2] Intensity of impact at a point [2] Duration of impact at a point [2] Rate of onset of the event [2] Predictability of the event [1] Natural hazards may be defined as "extreme events that originate in the biosphere, hydrosphere, lithosphere or atmosphere" [3] or "a potential threat to humans and their welfare" [1] which include earthquake, landslide, hurricane and tsunamis.

Understanding risk allows us to safely use fire, automobiles, and the stove in our kitchen, while avoiding actions that would make these hazards risky.

However, we consistently see reports of hazard identification presented as evidence of actual risk. Classification[ edit ] Hazards can be classified as different types in several ways.

The hazards from these bacteria can be avoided through risk mitigation steps such as proper handling, storingand cooking of food. Welding screens can be used to isolate welding operations from other workers. For example, iodine in the form of potassium iodate is used to produce iodised salt.

Identification of hazards assumes that the potential targets are defined. The relative difference of actual loss from the anticipated loss is called objective risk. If you see, hear or smell anything odd, take note.

In these extremes the natural occurrence may become an event that presents risk to the environment or people. Biological hazards include viruses, parasites, bacteria, food, fungi, and foreign toxins.

For example, the hazards of naturally-occurring bacteria such as Escherichia coli and Salmonellaare well known as disease-causing pathogens and a variety of measures have been taken to limit human exposure to these microorganisms through food safety, good personal hygiene and education.Risk assessment is the process where you: Identify hazards and risk factors that have the potential to cause harm (hazard identification).

Hazard Risk

Analyze and evaluate the risk associated with that hazard (risk analysis, and risk evaluation). Key Difference ā€“ Hazard vs Risk. It is a common experience that some words are considered as synonyms of each other as described in the dictionary whereas in real life there is a difference between the two in the context of usage.

The following points are substantial so far as the difference between risk and hazard is concerned: The term risk is described as a situation susceptible to harm, damage or loss.

On the other hand, hazard implies something which is a root to harm, danger or loss. Hazard and risk are often used interchangeably, but there is a significant and meaningful difference between the two terms.

When scientists and policymakers carelessly substitute one for the other, the confusion gets compounded. There are three steps used to manage health and safety at work.

Spot the Hazard (Hazard Identification) Assess the Risk (Risk Assessment) Make the Changes (Risk Control). The difference between hazard and risk is a critical distinction.

Hazard and risk describe two different but related concepts. The difference may sound like an unimportant jargon-filled distinction, but this difference is critical to understanding reports of hazards and risks.
