Introduction

A chemical importing company based in Mumbai contacted Diligence Certifications recently due to a large quantity of calcium carbide that the company received in bulk from its foreign supplier. The clearance of goods through customs has been done, logistics has been organized, and purchase orders from the industrial clients have been received already. The company was expecting delivery to start within two days.

However, there was one issue that arose during the compliance check. It turned out that there was no Calcium Carbide Storage License at the warehouse where the material was supposed to be stored. Thus, storage of the shipment was impossible without fulfilling regulatory requirements, and the company had to pay extra money on warehousing and delayed client orders.

This problem is common among the importers who spend a lot of time on the acquisition of Import Export Code (IEC), logistics and customs documentation, while storage issues are ignored. Considering the fact that calcium carbide produces flammable acetylene in contact with water, there is a danger for safety. That is why in India there is a need to obtain the license mentioned above before storing any quantity of calcium carbide.

For importers, obtaining the licence is not simply another regulatory formality. It protects employees, safeguards facilities, reduces operational risks, and enables uninterrupted business operations.

What is a Calcium Carbide Storage License?

Calcium Carbide Storage Licence is a mandatory document that serves as a regulatory permission needed by those who store calcium carbide in India. Due to the fact that calcium carbide forms acetylene gas which is highly flammable when it comes in contact with moisture, the storage facility needs to follow safety provisions provided in Explosives Rules and regulated by Petroleum and Explosives Safety Organisation (PESO). Those who intend to import, distribute, store or manufacture calcium carbide commercially shall secure the licence before operation.

The application is subject to review regarding the following aspects:

• Storage safety
• Fire prevention
• Ventilation
• Moisture protection
• Emergency preparedness
• Hazard management
• Operational safety procedures

Businesses should obtain the licence before storing commercial quantities rather than after shipments arrive.

Why is Calcium Carbide Regulated?

Calcium carbide has been applied in many industries, ranging from metal processing to welding, chemical manufacture, and other specialized industrial uses. Even though calcium carbide has proven to be beneficial, it poses special hazards regarding its storage.

This chemical starts reacting the moment it comes into contact with water or any high degree of humidity. As a result of this, there is the generation of acetylene gas, which is highly flammable.

Regulation objectives are simple:

• Protect workers
• Prevent industrial accidents
• Ensure safe handling practices
• Standardise storage procedures
• Reduce environmental and operational risks

Regulatory oversight therefore focuses on both the storage infrastructure and the operational practices adopted by the business.

Applicable Regulatory Authority

Calcium carbide storage in India comes under the rules of Explosives as per the relevant provisions of the Explosives Rules, which are controlled by the Petroleum and Explosives Safety Organization (PESO).

The PESO works under the Department of Promotion of Industry and Internal Trade (DPIIT) of the Ministry of Commerce and Industry in the Indian Government. It regulates dangerous goods that require special safety precautions.

Companies that deal in the manufacturing, importing, transportation, storage, and handling of hazardous chemicals must be regulated by the relevant regulatory body before starting their commercial activities.

Why is a Calcium Carbide Storage License Required?

Many companies believe that getting customs clearance means they are authorized to store their imported chemicals. In fact, it is important to know that there are two different requirements - import approval and storage approval.

Getting a Calcium Carbide Storage License proves that the storage site is assessed in accordance with required safety standards and is capable of dealing with hazardous chemicals.

Helps to Fulfill Legal Requirements

License makes sure that company complies with the necessary Indian safety legislation regulating storage of hazardous chemicals.

Protects Employees

Correct storage procedure makes accidents because of incorrect handling or moisture exposure unlikely.

Improves Business Operations

Regulatory inspections and compliance letters can disturb your business. It is more likely that you will be able to get through this process being licensed.

Builds Customer Trust

Most industrial consumers prefer companies which have correct regulatory approval. Correct storage site demonstrates a good approach towards safety and responsible business.

Minimizes Operational Risk

It is much cheaper to take care of compliance beforehand rather than dealing with safety incidents, shipment delays or legal issues after beginning operations.
