Kidde Inert 469 System for Marine and Industrial Systems

Kidde Fire Protection's 469 Inert extinguishing systems for Land based and Marine applications are inert gas blends consisting of a mixture of two or more gases found naturally in the atmosphere: Typically, Argon (Ar), Nitrogen (N2) and CO2. An Inert Gas discharge results in a gas mixture with a density similar to that of air. Inert Gas 469 Series (Restrictor Model)

Kidde Inert Gas System Benefits:

Clean Agent for protection of high value assets.

This is an Inert Gas extinguishing system for Industrial applications.

IG-55: Container Mix of 50% Nitrogen and 50% Argon

IG-541: Container Mix of 52% Nitrogen, 40% Argon & 8% Carbon Dioxide

IG-100: 100% Nitrogen

IG-01: 100% Argon

CONTAINERS

Container sizes from 15.9, 67.5, 80 and 140 litres, the latter providing a reduction in container quantity thus substantial cost saving for large projects. Each container is manufactured from high strength alloy steel and the assembly is TPED approved.

 

Lower Installation, Labor and Refill Costs

• Several sizes of pre-fabricated manifolds with pre-installed check valves ready for discharge hose connections

• Fast & easy installation using quick-connect actuation hoses and electrical connections

Economical agent refill cost after a discharge.

Why choose an inert gas system?

Safe for the Environment.

Pure Inert gases and the constituents of the blended versions are found naturally in the atmosphere. These gases are environmentally responsible, having an ozone depletion potential (ODP) of zero and a global warming potential (GWP) of zero. At room temperature, inert gases are colorless and odorless.

Safe for Human Exposure.

In occupied areas, people can breathe Inert gas blends at extinguishing concentrations below 52% for very brief periods of time during egress. There are no toxicological factors associated with the use of Inert gases as they will not decompose or produce any by-products when exposed to a flame.

Technical Specifications

• Actuate up to 60 cylinders with single electric actuator.

• Can be used with selector valves to protect multiple hazards from a single cylinder bank.

• Vent requirements equivalent to chemical clean agents due to flow controlled valve.

Applications for Kidde Inert Gas Systems:

• Art Galleries

• Control Rooms

• Electric Switch Rooms

• Financial Centres and Banks

• Medical Facilities

• Museums

• Petrochemical Installations

• Pharmaceutical Facilities

• Rare Book Libraries

• Record Storage Facilities

• Telecommunication Centres

EFFICIENT

Small and large-scale tests have proven that fire is extinguished quickly, before any serious damage can occur. This is achieved by reaching the minimum design concentration within the maximum two minute discharge period for Class A fires and 60 one minute for Class B fires.

COST-EFFECTIVE

By using its tried and trusted range of 150, 200 and 300 bar equipment, Kidde Fire Protection can offer a cost-effective fire extinguishing system

What is Kidde Fluoro-K? Is Fluoro-K the same as Novec?

What is Kidde Fluoro-K?
EXTINGUISHING AGENT

Fluoro-K™ Fire Suppression Clean Agent (herein referred to as “agent”) is a fluorinated ketone (Dodecafluoro-2-methylpentan- 3-one) compound of carbon, fluorine and oxygen (CF3CF2C(O)CF(CF3)2). It is colorless, electrically non-conduc- tive and has a low odor. 

Kidde Fire Systems Fluoro-K™ based clean agent fire suppression systems are safe, competitive, and costeffective fire suppression solutions for protecting assets in commercial, light, and heavy industrial applications.

The Fluoro-K agent itself is colorless, with low odor and no particulate or oily residue allowing for minimal business disruption after a discharge. From an environmental standpoint, Fluoro-K has zero ozone depletion potential, and an atmospheric lifetime of less than five days. 

Is Fluoro K the same as Novec?

Fluoro-K is a FK-5-1-12 chemical clean agent alternative to Novec 1230 (which will eventually be phased out), and which addresses the same purity and toxicity concerns associated with Halon. In most cases, a system originally designed for Novec requires no hardware changes if converted to using Fluoro-K.

What is the difference between Novec 1230 and fk-5-1-12?

What's the difference between Novec 1230 and FK-5-1-12? Simply put, Novec 1230 is a trade name or chemical name for the product manufactured by 3M. When the chemical is manufactured elsewhere, it meets the same specification and is governed by the same rules and regs. FK-5-1-12's chemical composition does not change.

Tại sao Dung Dịch Foam Chữa Cháy AFFF bị cấm? PFAS là gì?

Tại sao Dung Dịch Foam Chữa Cháy AFFF bị cấm?

Để đối phó với những lo ngại ngày càng tăng về các rủi ro về Sức Khỏe và Môi Trường do Dung Dịch Foam Chữa Cháy AFFF gây ra, một số tiểu bang đã có hành động lập pháp nhằm hạn chế hoặc cấm sử dụng chất này. Các biện pháp này phản ánh cam kết bảo vệ sức khỏe cộng đồng và môi trường khỏi những tác động có hại của các hợp chất PFAS (dung môi các chất có gốc perpolyfluoroalkyl).
Khi Dung Dịch Foam Chữa Cháy AFFF được sử dụng, thải ra hoặc thải ra môi trường, có thể cần phải hạn chế ngăn chặn và dọn dẹp để ngăn ngừa các tác động xấu đến sức khỏe hoặc môi trường trong tương lai.

Dung Dịch Foam Chữa Cháy AFFF & những khiếu nại liên quan đến Lính Cứu Hỏa? 
Bọt Foam Chữa Cháy, thường được gọi là AFFF, là một loại bọt chữa cháy được sử dụng để chữa cháy chất lỏng dễ cháy có nguy cơ cao (Class B). Mặc dù AFFF rất hiệu quả trong việc dập tắt các đám cháy Class B và cứu sống con người, nhưng gần đây người ta xác định rằng nó có độc tính cao vì nó chứa các dung môi các chất có gốc perpolyfluoroalkyl (PFAS). Ngày càng có nhiều bằng chứng khoa học và y tế ủng hộ nhóm nghiên cứu y khoa cho thấy việc tiếp xúc với PFOA và PFOS - PFAS được nghiên cứu kỹ lưỡng nhất cho đến nay khi tiếp xúc với Dung Dich Foam Chữa Cháy AFFF sẽ có liên quan đến ung thư thận, ung thư tuyến tụy, ung thư tinh hoàn, ung thư bàng quang, ung thư gan và ung thư tuyến tiền liệt. Nếu bạn nghi ngờ rằng bệnh ung thư của mình hoặc một tình trạng bệnh lý nghiêm trọng khác là do tiếp xúc với Dung Dich Foam Chữa Cháy AFFF, hãy liên hệ với các luật sư chuyên gia, những người sẽ giúp bạn lấy lại khoản bồi thường tài chính mà bạn xứng đáng được hưởng.

Ba loại PFAS là gì?
Các loại PFAS được nghiên cứu phổ biến nhất là dung môi các chất có chứ gốc axit perfluorooctanoic (PFOA) và axit perfluorooctane sulfonic (PFOS). Các loại được nghiên cứu phổ biến tiếp theo là axit perfluorohexane sulfonic (PFHxS) và axit perfluorononanoic (PFNA). Chúng được gọi là "Hóa Chất Vĩnh Cửu" vì chúng không phân hủy trong môi trường và có thể tích tụ trong các sinh vật sống.

PFAS là gì?

PFAS là hóa chất nhân tạo đã được sử dụng trong công nghiệp và các sản phẩm tiêu dùng trên toàn thế giới từ những năm 1940. Chúng đã được sử dụng để sản xuất đồ nấu nướng chống dính, quần áo chống thấm nước, vải và thảm chống bẩn, một số loại mỹ phẩm, một số loại bọt chữa cháy và các sản phẩm chống dầu mỡ, nước và dầu.

Các PFAS được nghiên cứu phổ biến nhất là axit perfluorooctanoic (PFOA) và axit perfluorooctane sulfonic (PFOS). Các PFAS được nghiên cứu phổ biến tiếp theo là axit perfluorohexane sulfonic (PFHxS) và axit perfluorononanoic (PFNA). PFOA và PFOS đã bị loại khỏi sản xuất và sử dụng tại Hoa Kỳ, nhưng các quốc gia khác vẫn có thể sản xuất và sử dụng chúng.

Trong quá trình sản xuất và sử dụng, PFAS có thể thẩm thấu vào đất, nước và không khí. Hầu hết PFAS (bao gồm PFOA và PFOS) không bị phân hủy, vì vậy chúng vẫn tồn tại trong môi trường. Do được sử dụng rộng rãi và tồn tại dai dẳng trong môi trường, PFAS được tìm thấy trong máu của con người và động vật trên khắp thế giới và có mặt ở mức thấp trong nhiều loại thực phẩm và môi trường. Một số PFAS có thể tích tụ trong cơ thể con người và động vật khi tiếp xúc nhiều lần theo thời gian.

Nhiều bài báo khoa học đã được công bố về việc tiếp xúc với PFAS và tác động đến sức khỏe. Mặc dù khó có thể chứng minh rằng các chất này trực tiếp gây ra các tình trạng sức khỏe ở con người, nhưng các nghiên cứu khoa học đã chỉ ra rằng việc tiếp xúc với một số PFAS trong môi trường có thể liên quan đến các tác động có hại đến sức khỏe ở người và động vật. Cần có nhiều nghiên cứu hơn nữa để hiểu rõ hơn về tác động của việc tiếp xúc với PFAS đối với sức khỏe.

Các loại PFAS mới đang được phát triển. Một số trong số chúng có thể có các đặc tính tương tự như PFAS hiện có và một số phân hủy rất chậm trong môi trường. Có rất ít nghiên cứu khoa học về PFAS mới, vì vậy cần có nhiều nghiên cứu hơn nữa để khám phá xem chúng có phải là mối quan tâm về sức khỏe hay không.
