Nohmi Bosai to Launch PFAS-Free Foam Fire Extinguishing System 'Green Squall' for Parking Lots in June 2026

Nohmi Bosai Ltd. (Headquarters: Chiyoda-ku, Tokyo; President: Masahiro Hasegawa; Capital: 13.302 billion yen; Tokyo Stock Exchange Prime Market) has obtained certification for 'Green Squall', a foam fire extinguishing system for specific parking lots. The system utilizes 'Global Form 1', a new foam fire extinguishing agent that does not use PFAS*1 (per- and polyfluoroalkyl substances). Sales will commence in June 2026.

This system resolves the challenges of maintaining foam fire extinguishing equipment for indoor parking lots, which have arisen due to the discontinuation of conventional aqueous film-forming foam extinguishing agents and stricter PFAS regulations. It ensures a stable supply for the future.

Nohmi Bosai Ltd. undertook this development as part of its sustainability management efforts towards 'PFAS elimination'. The company will continue to challenge itself to create a safer and more sustainable society to maintain the natural environment and social systems.

*1: A general term for organic fluorine compounds (perfluoroalkyl and polyfluoroalkyl substances). These substances do not decompose in the natural environment, raising concerns about their impact on the human body and ecosystems.

■ Development Background

In recent years, international regulations regarding the environmental impact of PFAS have been strengthened, leading to a global trend of discontinuing the production and restricting the use of aqueous film-forming foam fire extinguishing agents. In response, the company worked on developing alternative technologies that achieve high extinguishing performance while minimizing environmental impact, leading to this commercialization.

■ Overview

- System Name / Product Name: Foam Fire Extinguishing System for Specific Parking Lots / Green Squall
- Certification Number: Hyo-Sho-Tora No. 49
- Scope of Application: Indoor parking lots (Specific parking lots)

■ Features

1. Innovative Extinguishing Performance and Environmental/Human Safety
The system employs a PFAS-free surfactant that is considerate of the human body and the environment. Through a proprietary formulation, it achieves excellent extinguishing performance equal to or greater than aqueous film-forming foam, even with a smaller spray volume*2 compared to conventional foam heads, thanks to its water-like spray characteristics.*3
*2: Water spray volume per 1 square meter area.
*3: Foam fire extinguishing agents (aqueous solutions) must be disposed of as industrial waste.

2. Low-Volume Spray to Minimize Water Damage
By utilizing a closed-type foam solution head, the system detects and sprays only on the fire area (radius 2.3m, 35L/min) rather than conducting a simultaneous zonal spray like conventional foam fire extinguishing systems. This creates a simple and efficient system, reducing drainage load and minimizing water damage with a low water volume of 400L/min total, even when up to 10 heads are opened simultaneously.

3. Long-Term Stable Supply through an Integrated In-House System
By developing and manufacturing everything from the chemical agent to the dedicated equipment in-house, the company ensures a stable supply and prompt maintenance response into the future.
