According to Indian regulations, a chemical is considered "non-hazardous" if it does not meet the criteria outlined in the "Manufacture, Storage and Import of Hazardous Chemicals (MSIHC) Rules, 1989"

 According to Indian regulations, a chemical is considered "non-hazardous" if it does not meet the criteria outlined in the "Manufacture, Storage and Import of Hazardous Chemicals (MSIHC) Rules, 1989" which defines hazardous chemicals based on their physical, health, and environmental hazards, meaning a non-hazardous chemical would typically exhibit low toxicity, low reactivity, and minimal environmental impact, and would not require a detailed Safety Data Sheet (SDS) under most circumstances; however, it's important to consult the specific rules and schedules within the MSIHC for a complete understanding of what constitutes a non-hazardous chemical in India. 

Key points about non-hazardous chemicals in India:

No significant health hazards:

The chemical should not pose significant health risks like acute toxicity, irritation, sensitization, carcinogenicity, or reproductive toxicity when handled under normal conditions. 

Low physical hazards:

The chemical should not be highly flammable, explosive, or have a high reactivity that could lead to dangerous situations. 

Minimal environmental impact:

The chemical should not be considered a significant pollutant or have a high potential for environmental damage. 

No need for detailed SDS:

Generally, chemicals classified as non-hazardous do not require a comprehensive SDS, but manufacturers may still choose to provide basic safety information. 

Where to find the criteria:

The Manufacture, Storage and Import of Hazardous Chemicals (MSIHC) Rules, 1989:

This document outlines the specific criteria for classifying a chemical as hazardous, and therefore, chemicals not meeting these criteria are considered non-hazardous. 

Central Pollution Control Board (CPCB):

The CPCB is the primary agency responsible for implementing and monitoring the MSIHC rules and can provide further clarification on the classification of hazardous chemicals. 

Important considerations:

Context matters:

Even if a chemical is generally considered non-hazardous, its safety profile can vary depending on the concentration, exposure route, and specific workplace conditions. 

Consult with experts:

If you are unsure whether a chemical is hazardous, always consult with a qualified safety professional or regulatory authority for guidance.
