The application of a formal systematic critical examination to the process and engineering intentions of new or existing facilities to assess the hazard potential of mal-operation or mal-function of individual items of equipments and their consequential effects on the facility as a whole.

Source models represent the material release process. They provide useful information for determining the consequences of an accident, including the rate of material release, the total quantity released and the physical state of the material.

Dispersion models describe the airborne transport of toxic/inflammable materials away from the accident site and into the plant and community.

Risk is defined as a measure of economic loss or human injury in terms of both the likelihood and the magnitude of the loss or injury.

The following activities are covered under MSIHC

• An operation or process listed in Schedule 4 carried out in an industrial installation involving one or more hazardous chemicals
• An isolated storage involving one or more hazardous chemicals listed in Schedule 2, and
• Pipeline for conveyance of a hazardous chemical other than the flammable gas at a pressure of less than 8 bars absolute

The chemicals fulfilling the criteria given in Part I and/or listed in Part II of Schedule I and chemicals listed in Schedule 2 and 3 are covered under MSIHC Rules

If one of the operations or processes listed in Schedule 4 is carried out in a factory involving one or more hazardous chemicals, an occupier has to first ascertain the category to which his factory belongs i.e. whether the factory comes under lower-tier, middle-tier or higher-tier because the requirements/ provisions are different for different categories of factories

The three categories of factories are given below :

The Factories Act and the rules framed thereunder are enforced by respective states/UTs. through the office of Chief Inspector of Factories under the Labour Department of the State Government/UTs.

The State Government is empowered to declare that al or any of the provisions of the Act shall apply to any place wherein manufacturing process carried out irrespective of number of workers employed therein.

The State Government may exempt with certain conditions, in workshops whether manufacturing processes are carried out for purposes of education, training, research or reformation from all or any of the provisions of this Act.

Yes, It is compulsory. The approval, license and registration of a factory is compulsory before starting the manufacturing process. The occupier of the factory should submit the plan to the Chief Inspector of the State for approval. After the approval, the licensee will be granted by the CIF and the factory will be registered.

There are many provisions, which are to be strictly followed by the occupier. The details are available in a publication known as the Factories Act, 1948. There are 120 sections divided into 11 chapters, which can be referred for detailed information.

The workshop for Safety Committee Members is conducted twice in a year. No. of participants would be around 25-30 per batch.
