BIS Certification for Wheeled Fire Extinguisher

BIS Certification for Wheeled Fire Extinguishers | IS 16018:2012 | BIS Consultancy

Introduction

Wheeled fire extinguishers are high-capacity mobile fire-fighting equipment designed for locations where a larger quantity of extinguishing agent and higher discharge capacity are required. They are commonly used in industrial plants, warehouses, refineries, workshops, storage areas and other locations having significant fire hazards.

Because these extinguishers are pressure-containing safety equipment, their construction, materials, discharge performance, fire-fighting capability, pressure resistance, corrosion resistance and operational durability must meet specified quality requirements.

In India, Wheeled Fire Extinguishers are covered under IS 16018:2012 – Wheeled Fire Extinguishers – Performance and Construction – Specification. The product is included in the mandatory Fire Extinguishers (Quality Control) Order, 2023, which requires covered products to conform to the applicable Indian Standard and bear the Standard Mark under a BIS licence according to Scheme-I.

Qualitance India provides end-to-end BIS Certification consultancy for Wheeled Fire Extinguisher manufacturers, including product scope assessment, documentation, laboratory testing coordination, factory inspection preparation, technical compliance and BIS licence support.

What Are Wheeled Fire Extinguishers?

Wheeled fire extinguishers are fire extinguishers mounted on wheels or a wheeled arrangement so that larger extinguishers can be moved and operated at the location of a fire.

They are particularly useful where:

Large quantities of extinguishing media are required
Fire hazards are comparatively high
The extinguisher cannot conveniently be carried manually
A longer discharge duration or larger discharge quantity is required
Industrial and outdoor fire protection is necessary

BIS's fire-extinguisher compendium states that IS 16018:2012 covers wheeled extinguishers with a fully charged mass from 17 kg to 450 kg and includes equipment using water, dry powder, foam, carbon dioxide or clean agents, as applicable.

BIS Standard for Wheeled Fire Extinguishers

The applicable standard is:

IS 16018:2012 – Wheeled Fire Extinguishers – Performance and Construction – Specification

The BIS Product Manual is PM/IS 16018/1/March 2019 and is issued under Scheme-I of the BIS Conformity Assessment Regulations, 2018.

The standard has subsequently been amended. BIS issued guidelines for implementation of Amendment No. 3 to IS 16018:2012, with the implementation deadline of 22 March 2025.

Therefore, manufacturers must ensure compliance with the applicable current version of IS 16018:2012 together with the amendments notified by BIS.

Is BIS Certification Mandatory for Wheeled Fire Extinguishers?

Yes.

The current BIS Scheme-I product list includes:

IS 16018:2012 – Wheeled Fire Extinguishers

under the Fire Extinguishers (Quality Control) Order, 2023.

The QCO requires the specified products to conform to the corresponding Indian Standard and carry the Standard Mark under a BIS licence as per Scheme-I. It also states that the latest version of the relevant Indian Standard, including amendments notified by BIS, applies from the date notified by BIS.

The Order specifically excludes goods manufactured in India for export, subject to the provisions of the Order.

Fire Extinguishers Quality Control Order

The Fire Extinguishers (Quality Control) Order, 2023 was issued by the Ministry of Commerce and Industry on 9 August 2023. It covers both:
