UK releases provisional ozone depleting substances common framework

The Ozone-Depleting Substances (ODS) and Fluorinated Greenhouse Gases (F-gases) UK Common Framework has been published in a provisional form on GOV.UK. The framework is accessible here.

This command paper sets out how the UK government and devolved governments propose to work together on the regulation of substances that deplete the ozone layer and fluorinated greenhouse gases.

The provisional Common Framework has received ministerial approval from all four governments. It was laid in the UK Parliament to enable parliamentary scrutiny to begin.

Traditionally, fire extinguishers have utilised halogens (CFCs). They also harm aquatic systems and contaminate water supplies along with the ozone layer.

Experts have long professed the use of pyrocool, which is a nontoxic, biodegradable, fire-extinguishing, and cooling agent. It’s said to replace the traditional extinguishers, and is just as effective in putting out fires, does not deplete the ozone layer, or persist in the environment, unlike CFCs.

Survitec: Better crew training needed for CO2 firefighting systems

Survitec is advising the maritime industry to ensure fixed fire-fighting systems are commissioned by their original equipment manufacturers and that crews undergo basic system configuration training, following a spate of incidents where ship fires have been exacerbated through incorrect use or installation of CO2-based extinguishing systems.

While the International Maritime Organization’s FSS Code provides engineering and design standards for all types of fire extinguishing systems, there are no mandatory regulations governing their installation and commissioning, only recommendations. Standards on operation and maintenance have improved over the last years but in many cases, they are still seen as guidelines

Survitec said that although these guidelines should be followed, there have been several incidents in recent times where fixed fire extinguishing systems have failed.

“While it is difficult to put a number on all the fire related incidents where incorrect installation, operation or maintenance of a fixed firefighting system has resulted in system failure, injury or death, the subsequent accident investigations offer a difference perspective on the effectiveness of the current regulations and guidelines,” said Mats Hestmann, Survitec Group QHSE Manager.

“Fire safety systems are inherently designed to protect and save lives. However, if these systems are incorrectly used, installed or insufficiently inspected and maintained, the consequences can be severe,” said Hestmann.

MSC.1/CIRC 1318, the Guidelines for the Maintenance and Inspections of Fixed Carbon Dioxide Fire-Extinguishing systems was released in June 2009 and have been adopted by most Flag states, but some are still following their own set of standards.

Hestmann, believes that it would be beneficial for MSC.1/CIRC 1318 to become even more structured as is the case with MSC 1432, clearly defining what should be inspected. Once the majority of flag states have adopted an MSC circular, it then becomes a resolution making it mandatory.

He adds: “Great improvements to safety have come as a result of IACS Z-17 Service provider approvals. However, it’s not the failure of the firefighting system that is resulting in so many incidents, but rather the lack of system knowledge and poor operator training.

“There should be more effective rules governing system training; because a crew member is familiar with one firefighting system doesn’t mean they are appropriately trained to use another manufacturer’s system or even a different system configuration. While the product itself might be standard, the layout of the system, the location of valves, cylinders, and vents and so on will differ from ship to ship. Certainly, crews need to be better trained in the use, operation and maintenance of these systems.”

Erik Christensen, Technical Director Fire Fighting said: “We have seen a number of incident reports where human error in the use of firefighting systems is a common factor. Valves have been closed when they should have been open, ventilation flaps left open with main generators still running during the fire.

“Carbon Dioxide is a dangerous gas and any system that has been incorrectly installed, maintained or operated could not only fail to extinguish the fire but be very harmful to the crew.”

As the market leader and a champion of maritime safety initiatives, Survitec is fostering greater fire safety and systems awareness across the industry. It has already issued advice notices and is raising wider awareness of the need to ensure firefighting systems are correctly installed, regularly maintained, serviced and that crew operating the systems are trained and understand how to use the specific system.

“We want to ensure that operators and crews have a much better understanding of how fixed firefighting systems operate and the importance of regular, properly carried-out maintenance. With greater knowledge, they will be able to overcome many of the operational challenges they face and prevent system failure when it is required in an emergency.

“Crews can be better equipped to fight fires more effectively, more safely, but any initiative needs to work in harmony with the rules, some of which could do well to be revised,” said Hestmann.

New document published on portable aerosol dispensers for fire extinguishing purposes

New British standard, BS EN 16856:2020 – “Portable aerosol dispensers for fire extinguishing purposes” has been published.

This document specifies the requirements for non-refillable portable aerosol dispensers for fire extinguishing purposes.

It supplements the characteristics, performance and test methods for extinguishing aerosol dispensers for fire extinguishing purposes, in addition to the requirements of the Directive 75/324/EEC. Requirements in this document are specified for products containing less than 1 kg or 1 l of extinguishing media, which can be expelled by the action of internal pressure and are intended to extinguish test fires of type A + B, or type A + F, or type A + B + F classes of EN 2. These extinguishing aerosol dispensers are intended to be used by untrained persons for domestic applications. They are not intended to be used on gas fires (class C) and metal fires (class D).

Requirements are specified for minimum performance in Annex I for extinguishing test fires of type A, type B and type F classes of EN 2, as appropriate.

Annex A gives the conditioning to be applied to extinguishing aerosol dispensers prior to testing as described in Annex B to Annex K.

Ultra Fog’s water mist systems

Ultra Fog water mist fire extinguishing systems provide robust, effective, quality engineered solutions for applications which require optimal fire suppression while minimising the volume of water consumed and deployed. High pressure pumps force water through the stainless steel Ultra Fog water mist nozzles, discharging the water in the form of millions of tiny droplets – typically 30 – 200 µm diameter.

An activated system will create a blanket of water mist droplets which maximise heat absorption from the fire, and subsequently displacing oxygen upon evaporation and expansion of the water mist as it converts to steam. Water mist systems are differentiated from sprinkler systems by mist’s unique ability to present a much greater water surface area (enabling rapid heat absorption), combined with the mist’s ability to remain suspended in the air for a much longer duration – thereby creating more exposure time for the heat absorption to take effect. This enables water mist systems to cool and suppress fire using considerably less water than sprinkler systems.

Euralarm releases guide on periodic testing in fixed firefighting systems

Euralarm has published a guidance document on the important aspects relating to the periodic inspection of cylinders used in fixed gaseous fire extinguishing systems and especially in respect to hydrostatic testing. The guidance note is intended to identify some critical areas that are often not fully understood and does not prescribe the full processes involved in the testing or the physical handling of the cylinders.

Transportable cylinders under the TPED (Transportable Pressure Equipment Directive) and ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road) are required to go through periodic testing for re-certification. The new Euralarm document addresses the issues related to the importance of procedures for periodic testing and subsequent refilling the cylinders.

The document guides the reader to avoid serious safety issues of hydrostatic testing. The guidance note is meant for the testing of gas cylinders of seamless steel, seamless aluminium alloy and welded carbon steel according to respectively EN 1968:2002, EN 1802:2002 and EN 1803:2002.

Aspects that are covered in the guidance note are moisture control, the reuse of cylinder valves and the recertification of cylinders. A useful checklist is part of the document. The checklist covers important steps to ensure that the safety of cylinders is maintained during periodic inspection processes and during the filling afterwards.
