This course was designed to provide students with a solid foundation in the development of environmental risks and hazards which emphases the human-environment relationship a recurring theme in all of our department courses. Environmental risks are often defined as the product of a hazard and the likelihood of its occurring using a simple formula that defines a risk as the product of probability of an event and its severity measured in terms of the population exposed and the nature of the consequences.

To fulfill this responsibility employers must implement the necessary precautionary measures to pinpoint and eliminate potential workplace hazards. Here are five types of environmental hazards that employers need to inform workers about. Jobs that involve handling chemicals present health risks to the employees.
Exposure to substances such as corrosives fumes vapors liquids and dust. When a state substance or an event has the potential to threaten the circumstantial natural environment like natural disasters and pollution and harmfully affect the health of the people then they are known as environmental hazards. An environmental hazard is a condition that adversely affects the environment.
Any type of pollutants like pesticides heavy metals biological. The selected 11 natural hazards are. Avalanches droughts earthquakes extreme temperatures floods forest fires landslides storm surges tsunamis volcanic eruptions winter and tropical storms.

Using a wealth of examples and case studies the book helps readers develop both a. HAZARD IDENTIFICATION HAZID The Civil Engineer has to possess certain knowledge of the Hazard identification is carried out by studying the process more complicated techniques used to evaluate the risk to the involved in the industrial activity the piping and environment and to manage the hazards and accidents instrumentation and control systems. This involves the arising from the risk.
16 Theoretical relationships between the severity of environmental hazard probability and risk. 13 17 A schematic illustration of the chain of development of a drought disaster. 14 18 Some factors that divide the MDCs and the LDCs.
16 19 Socio-economic factors and fatality rates during flash floods in Nepal July 1993. 19 21 The potential consequences of environmental hazards. The monitoring and control of environmental hazards to health entails a wide range of actions each tailored to the particular hazard or form of public health concern.
Monitoring implies use of routine measurements to detect changes in the environment or health and can be based on data from a wide variety of sources. An estimated 25 of death and disease globally and nearly 35 in regions such as sub-Saharan Africa is linked to environmental hazards. Some key areas of risk include the following.

Risk assessment and management is an integral part of the efforts needed to deal with environmental hazards to health.
WHO has been and continues to be actively involved in risk assessment and management of environmental hazards. This work involves WHOHQ Regional Offices regional environmental health centres. Environmental risks are often defined as the product of a hazard and the likelihood of its occurring using a simple formula that defines a risk as the product of probability of an event and its severity measured in terms of the population exposed and the nature of the consequences.
Modern society is said to have restructured in reaction to contemporary hazards with the aim of improving its management of risk. This implies that pre-industrial societies were somehow fundamentally different. In this paper we challenge that hypothesis by examining the ways in which risks associated with environmental hazards were managed and mitigated during the Middle Ages.
Hazards and risks include chemical biological or physical agents that have potential negative impacts on the economy environment and community. There is a wide range of hazards and risks to be considered as part of environmental impact assessment for State significant projects. These are the responsibility of different government agencies and have different policies that are provided for below.
