FM200 Pre-Commissioning Check List

FM200 Pre-Commissioning Check List 

NOTE:

Why is Halon banned? Halon, which was once one of the most effective and popular agents for suppressing fires, was banned because it is an ozone-depleting chemical. ... Since the ban on Halon 1211 and 1301, FM-200 has become a leading clean agent commonly used in gaseous fire suppression systems for the last 20+ years. FM come from Factory Mutual.
The manufacturing of FM-200 (HFC-227ea / Hydrofluorocarbons (HFC)) is being phased down as part of the AIM Act recently passed by Congress. ... Also known as HFC-227ea in NFPA 2001 Standard, this agent is odorless, colorless, liquefied compressed gas that discharges as an electrically non-conductive, clear vapor.

The atmospheric lifetime of FM-200 has been determined to be 36.5 years. The EPA does not consider FM-200 to be a long-lived substance when discharged, and as such, has placed no restrictions on its use.

To monitor the quality of the FM-200 pipework throughout different stages and before testing and commissioning works taking place, checklists will be completed by the project team [client, commissioning manager, designer, and installer/contractor].

The stages at when these checks will be completed are:

• delivery,
• storage,
• installation &
• pre-commissioning/pre-functional

Once the delivery, storage, installation, and pre-commissioning/functional checks have been completed, the pressure testing can commence.

Delivery Inspection

Once the FM-200 pipework and ancillaries arrive at the site, usually delivered by a transport company, the following should be checked with the driver before being accepted into storage.

Any noted damage should be reported immediately in writing to the manufacturer/supplier, supported with photographs.

REF	INSPECTION/TASK
1	Supplier's consolidated delivery ticket is available, showing all equipment and ancillaries for inspection and being used to check the delivery.
2	A copy of the order is available for reference and used to review the delivery.
3	Pipework is packaged with end caps to protect the internal surfaces.
4	Pipework has the correct wall thickness.
5	Pipework has suitable flanges.
6	Pipework is dry internally.
7	Pipework is not damaged.
8	Pipework surfaces are clean and not scratched
9	Paint has been applied to the pipework where required and is in good condition.
10	All ancillaries are included in delivery as per the order and delivery note
11	Replace any protection that has been removed

Storage Inspection

Storage Area

If the FM-200 pipework is to be placed into storage on-site before installation, there should be an inspection completed checking the following.

REF	INSPECTION/TASK
1	The area is internal and shall not be affected by the weather.
2	If the pipework & ancillaries are not to be stored internally but externally, there is sufficient protection to protect it from weather and ambient conditions.
3	The surface where the pipework & ancillaries are to be placed is flat.
4	The area is well covered and protected.
5	The area is well ventilated and has no risk of high humidity.
6	The area is clean & dust-free.

Storage of the FM-200 Pipework & Ancillaries

Before the pipework is placed into storage, the following should be checked.

[note: due to the risks involved, the gas cylinders shall not be stored on-site, they shall be delivered and installed just before handover and documented separately].

REF	INSPECTION/TASK
1	Pipework & ancillaries will not be over stacked.
2	Pipework & ancillaries shall not have materials stacked on them.
3	All ancillaries shall be placed in a safe and secure location so items do not go missing or get damaged.
4	Pipework/connection caps protecting the flanges are not removed.
5	The pipework shall be raised from the floor to allow airflow and stop the risk of water ingress.

Pre-Installation Inspection

Before the pipework & ancillaries are installed, the following should be checked.

REF	INSPECTION/TASK
1	The bracketry is ready and can bear the weight of the installation, and has been spaced correctly.
2	The room/area is dry and watertight.
3	The area being installed is not prone to flooding or ponding of water.
4	The room/area the pipework will be installed into is clean and dust-free. If there is dust/construction work, the pipework should be protected from concrete dust, cement.
5	Check to ensure that all connection kits containing - gaskets, bolts are available to allow bolting up of the pipework.
6	Pipework is clean and free of damage

Maintenance/Access

REF	INSPECTION/TASK
1	There is enough space allowed around and above the pipework once installed to perform maintenance and remove components, where required [check the manufacturer's maintenance instructions for requirements]

Pre-Commissioning Inspection

Once the pipework has been installed and before the functional testing and commissioning phase, the following shall be checked.

General

REF	INSPECTION/TASK
1	Pipework & ancillaries are installed according to the project drawings & manufacturers' requirements [size, nozzle location].
2	Discharge nozzles are installed and oriented per the manufacturer's requirements.
3	Where nozzle deflectors have been installed, they are positioned according to the manufacturer's requirements.
4	There is no risk of potential harm or injury from installing the nozzles and bracketry.
5	There is no risk of loose objects being stored within the space on shelves, cabinets, or similar surfaces, near to the discharge nozzles from becoming projectiles.
6	Piping is free to expand and contract without noise or damage to hangers, joints, or the building.
7	Pipework does not put undue stress on ancillaries and equipment, connected and bracketed to support itself.
8	Seismic restraints, where required, installed.
9	All piping supports and hangers meet criteria set out in the specifications & manufacturers' requirements, including being securely fastened to prevent unwanted vertical or lateral movement during discharge.
10	The pipework has been internally inspected to verify that there is no oil or dirt/debris within it that could cause an issue to the operation of the system discharge.
11	Any changes in pipe sizes are made with the proper sized reducing fittings.
12	All fittings meet specification requirements & manufacturers' requirements.
13	All fittings and ancillaries are rated correctly and in line with the system's pressure & manufacturers' requirements.
14	All equipment requiring maintenance is accessible (valves, junction boxes).
15	Piping does not block access to equipment that is part of this system or another system.
16	All valves are installed as per the drawing & manufacturers' requirements.
17	Pipework is insulated as per the specification and vapor sealed where required.
18	Piping is installed, ensuring that insulation shall not contact adjacent surfaces.
19	Any pipe openings are temporarily sealed to maintain piping system cleanliness & integrity for testing.
20	All components, including valves and controls, are labeled according to the project naming convention.
21	Valves/check valves have been installed according to the manufacturer's requirements and are in the correct direction.
22	All pressure gauges installed and display scale as per design & manufacturers' requirements.
