When Explosive Storage Approval Is Required
Storage approval becomes relevant once explosives are kept on a site rather than consumed on delivery. The common situations:
- Quarrying and mining operations holding a working stock between deliveries.
- Infrastructure and demolition contractors maintaining a magazine near a project.
- Dealers and distributors holding stock for supply.
- Fireworks businesses where the quantity and category bring the storage within the rules.
- Manufacturers holding finished product or explosive raw materials on site.
Two qualifications matter. First, whether a material is an explosive within the meaning of the Act is a legal classification question, not a matter of commercial description. Second, related materials sit under separate frameworks — ammonium nitrate under the Ammonium Nitrate Rules, 2012 and calcium carbide under the Calcium Carbide Rules, 1987 — and an explosive storage licence does not cover them.
Sequence matters more here than anywhere else. Siting, distances and construction are approved on drawings. Build first and you may find the structure cannot be approved where it stands, with no remedy short of relocation.
Magazine & Storage Requirements
A magazine is a defined structure, and its approval rests on the combination of where it sits, how it is built and what it will hold.
Location
- Distance to protected works as defined in the rules
- Distance to the site boundary and to other magazines
- Surrounding development, present and reasonably foreseeable
- Access for delivery and for emergency services
Construction
- Wall, roof and door specification for the category held
- Ventilation arrangements
- Lightning protection
- Mounding or separation where required
- Security fencing, lighting and access control
Requirements are driven by the category and quantity of explosive, so they are established case by case against the rules rather than from a standard specification. The approved quantity then becomes a binding limit on the site.
Documents for Application
Storage applications are drawing-led. The paperwork supports the drawing rather than the other way round.
- Site plan and key plan showing the magazine position and all protected works within the relevant distance
- Magazine construction drawings with materials and dimensions
- Land ownership or lease documents for the site
- Company constitution documents and authorisation for the signatory
- NOC from the District Collector or Police Commissioner, as applicable
- Antecedent verification of the applicant, where required
- Category and quantity proposed to be stored
- Security, custody and record-keeping arrangements
- Existing licence with approved drawing, for renewal or amendment
The District Authority NOC is the item that most often sets the real schedule. Its lead time sits outside the licensing process, so it belongs at the front of the plan.
Site Layout & Safety Compliance
The drawing does more work in explosive storage than in any other PESO application. It has to show not only your own structures but the surroundings that determine whether the position is acceptable at all.
Recurring problems:
- Incomplete protected works. A drawing showing only the applicant’s plot, omitting features beyond the boundary that affect the position.
- Stale surroundings. A base drawing prepared years ago, since overtaken by development on adjoining land.
- Scale and dimension errors. Distances that do not survive measurement.
- Construction detail omitted. Wall and roof specification, ventilation and lightning protection not shown to the level required.
- Quantity inconsistency. A proposed holding that does not match the layout or the construction submitted.
Where surrounding development has changed since an approved drawing was issued, the position needs re-establishing rather than reproducing.
Inspection Process
Where an inspection applies, the magazine is examined against its approved drawing and the licence conditions together. The site does not only have to be built correctly; it has to be run correctly.
- A tank or vessel relocated during construction, never reflected in the approved drawing
- Stored quantities that have crept above the licensed figure
- Safety fittings replaced with a different make or specification
- Electrical equipment in a classified area whose approval status nobody has checked
- Distances on the drawing that do not survive a tape measure
- A site team that has never seen the drawing filed on their behalf
In addition to the physical check, expect attention to registers of receipt and issue, the current balance against the approved quantity, lightning protection test records, and the list of authorised persons. These should be current, not assembled the week before.
What a consultant can and cannot do. We prepare the file, brief your site team and draft replies to departmental observations. We have no role in how an inspection is conducted and no influence over its outcome. A One Consultant is a private consultancy — not a government body, and not appointed or authorised by one. Our practice does not extend to GPCB, CPCB or Drug Department matters.
Renewal & Changes
Validity and renewal cut-offs are set by the applicable rules and differ by licence type, so check your licence document rather than relying on a general figure. Begin early where a collateral NOC must be refreshed, since that lead time is outside your control.
A fresh application or amendment generally becomes necessary when the category or quantity changes, the magazine is modified, extended or relocated, surrounding development alters the distance position, or the licence holder, constitution or occupancy changes. Do not assume a licence moves with a site on sale — verify it during due diligence.
Gujarat Industrial Area Support
Explosive storage follows quarrying, infrastructure and specific manufacturing rather than an industrial estate, so the work is spread across the state rather than clustered. We work across Gujarat from our office at GIDC Char Rasta in Vapi, most readily across the southern and central belt including Valsad, Surat, Bharuch, Vadodara and the Ahmedabad region.
For Gujarat applicants, the relevant PESO field office is the Vadodara Circle Office, headed by a Joint Chief Controller of Explosives.
Our involvement covers siting and layout planning, construction specification documentation, NOC coordination, application preparation and departmental correspondence. We do not guarantee approval and have no role in how an inspection is conducted.
FAQs
When is an explosive storage licence required?
Once explosives are kept on a site rather than consumed on delivery, storage approval generally becomes relevant. The precise position depends on the category and quantity held and on the classification of the material under the Explosives Act.
Can we build the magazine first and apply afterwards?
That is the most costly sequencing error in this framework. Siting, distances and construction are approved on drawings, and a structure built in an unapprovable position may have no remedy short of relocation. Establish the position before construction.
What distances apply to a magazine?
Distances are determined by the category and quantity stored, measured to protected works as defined in the rules. They cannot be stated as a single figure and must be established for your specific case.
What is usually the longest part of the process?
In practice the collateral approvals, particularly the NOC from the District Collector or Police Commissioner. Their lead time sits outside the licensing timeline, so they should be started first rather than in parallel with everything else.
Does surrounding development affect an existing approval?
It can. Distances are measured to protected works, and construction on adjoining land can change the position established when your drawing was approved. This is worth reviewing before a renewal rather than discovering during one.
Are we limited to the quantity stated on the licence?
Yes. The approved holding is a licence condition, and exceeding it is a compliance failure regardless of the magazine’s physical capacity. Increasing the holding requires an amendment.
Does the storage licence cover ammonium nitrate?
No. Ammonium nitrate is regulated under the Ammonium Nitrate Rules, 2012, a separate framework with its own requirements. Calcium carbide similarly falls under the Calcium Carbide Rules, 1987.
What records should we keep at the magazine?
Registers of receipt, issue and balance, lightning protection test records, and the list of authorised persons, all maintained currently. An inspection examines the licence conditions as well as the structure.
