The rapid increase in the transportation of hazardous chemicals has enhanced the accident potential during transit. In transit, the goods would subject to impact, vibration, compression and other adverse effects and exposure to harmful environment. The other factors such as improper packing of the contents, poor storage may also lead to release of chemicals to the environment resulting in emergencies like fire, explosion, toxic release, etc.


Apart from pollution of land, water and air, such emergencies have potential to cause injuries and death, property damage and environmental degradation. Availability of information on the hazards and control measures at the time of emergency is vital for minimizing the effect of such accidents. This module is intended to provide the first hand knowledge about the hazard information system as implemented in India and its status of implementation.

This module is for the following target groups:

  • Traffic Police
  • Industries
  • Transporters
  • Emergency Managers
  • Fire Fighters
  • Drivers




The likelihood that a considered occurrence will take, place.


Any unplanned, sudden event which causes or is liable to cause injury to people or damage to building, plant, material or the environment.


Result of a specific event.

Emergency plan:

A formal written plan which, on the basis of identified potential accidents together with their consequences, describe how such accidents and their consequences should be handled either on-site or off-site.


Evacuate means to move all people from a threatened area to a safer place. To perform an evacuation, there must be enough time for people to be warned, to get ready, and to leave an area. Generally, if there is enough time for evacuation, it Is likely to be the best protective action.


An inherent property of a substance, agent, source of energy or situation having the potential of causing undesirable consequences.


Accidents and/or near misses.

Hazardous substances:

An element, compound, mixture or preparation which, by virtue of chemical, physical or (eco) toxicological properties constitutes a hazard.

In-place protection:

In-place protection means to direct people to quickly go inside a building and remain inside until the danger passes. When protecting people inside, direct them to close all doors and windows and to shut off all ventilating, heating and cooling systems. In-place protection is used when evacuating the public would cause greater risk than directing them to stay where they are, or when an evacuation cannot be performed. When inside people must keep all windows and doors closed. In-place protection may not be the best option if the vapours are explosive, if it will take a long time for the gas to clear the area, or if the buildings cannot be tightly closed.


Isolate Hazard Area and Deny Entry means to keep everybody away from the area if they are not directly involved in emergency response operations. Unprotected emergency responders should not be allowed within the isolation area. This 'Isolation" task is done first to get control of a place to work. This is the first step for any protective action that follows.

Major accidents:

Any unplanned, sudden event which causes or is liable to cause serious injury to people or damage to buildings, plant, material or the environment.


The combination of a consequence and the probability of its occurrence.

Risk assessment:

The value judgment of the significance of the risk, identified by a risk analysis taking into account any relevant criteria.

Risk management:

Actions taken to achieve or improve the safety of the installation and its operation.


This means movement of hazardous substances from one place to another or air, rail, road or water.


A person or an organisation engaged in the offsite transportation of a hazardous substances by air, rail, road or water.
