Disaster Site Management

Management of activities before, during and after an emergency is a difficult task. Different components must be considered to account for all the potential hazards that can be faced. The preparation of a comprehensive disaster management plan is vital to ensure the correct management of resources, consecution of activities and the protection of emergency response and recovery workers. During the elaboration of a disaster management plan, potential hazards can be identified which helps to establish the necessary measures to prevent, control, and mitigate those hazards. Such measures can include but are not limited to the establishment of a system to manage personnel during an emergency, provide training to face a particular hazard, define the use of personal protective equipment, and install guidelines and mechanisms to be used in case of an emergency, among others.

This topic page includes general information on Disaster Site Management. The site provides a series of reports on emergency responders’ safety management in disaster and terrorism response. The different reports cover topics such as rubble and debris, dust and smoke, heat, anthrax, stress, types and use of protective equipment, hazard assessment, risk communications, site management, structural collapse, fire, and explosions. The disaster management page also offers information on other hazards that may be involved in a disaster management task, such as asbestos, carbon monoxide, electrocution, confined spaces, falls, heat stress, chemical and structural hazards, and provides guidance on identifying and handling human remains. Other possible hazardous substances and situations such as chemical and structural hazards are also included in the website to ensure the health and safety of workers.

asbestos with penny showing relationship

Asbestos is the name used to group a class of naturally occurring mineral fibers that have been widely used in the industry and is associated with adverse effects on human health. Asbestos fibers have been widely used in industrial and commercial applications because of its strength, flexibility and electrical and heat resistant properties. Some examples of its applications include automobile brakes, insulation materials, vermiculite, cement, and talc. When the mineral fibers are handled, they can be released into the air and be inhaled, because of their microscopic size and fibrous nature, which can lead to asbestos accumulating in the lungs and causing respiratory illness. Exposure to asbestos has been associated with adverse health effects such as lung cancer, asbestosis and mesothelioma.

Asbestos is well recognized as a health hazard and is highly regulated. An estimated 1.3 million employees in the construction and general industry face significant asbestos exposure on the job. Heaviest exposures occur in the construction industry, particularly during the removal of asbestos during renovation or demolition. Employees are also likely to be exposed during the manufacture of asbestos products (such as textiles, friction products, insulation, and other building materials) and during automotive brake and clutch repair work. In such cases that workers must have contact with asbestos, the use of personal protective equipment is necessary to prevent any potential exposure to the material.

Carbon monoxide (CO) is a gas produced as the result of incomplete combustion processes and is characterized by being odorless and colorless. Carbon Monoxide has the ability to combine to hemoglobin forming carboxyhemoglobin. This process inhibits the ability of hemoglobin to transport oxygen, leading to an oxygen deficiency that may result in permanent heart and brain damage or even death. CO properties make it especially difficult to detect, which increases the risk of injury or death by the inhalation of the gas.

During an emergency, usually electrical power deficiencies increase the use of gas powered generators generating CO and some workers may place generators in enclosed spaces which can lead to the accumulation of the gas resulting in CO poisoning.
