To ensure correct handling of pressurized cylinders.
All staff involved in the handling of pressurized INERGEN cylinders used in Fire Eater systems.
Contractors using Fire Eater components in their INERGEN systems contracting activities, must be informed about this instruction, and a commitment from the customer to the fulfilment of the enclosed requirements must be available prior to any sales.
Contractor: Fire Eater’s customer registered in NAV with a discount on the component pricelist, or any customer who purchases INERGEN system components based on a quote, for the intended use in a system installed and/or delivered by the customer to a 3rd party.
Valve cap: Open or closed device attached to or permanently installed on the cylinder to protect the cylinder valve.
Discharge valve: Valve that is attached to the cylinder valve with the type name IV* (e.g. IV4, IV7, IV8 etc.)
No employee in Fire Eater may engage in work involving handling of pressurized cylinders or attachment of equipment hereto, unless the following registration of qualifications has been made:
Pt. 1-5 mentioned below: “Warehouse work”” or “Installation INERGEN”.
Pt. 6-11 mentioned below: “Installation INERGEN”.
Pt. 12 mentioned below: “Installation INERGEN” and “Booster”
It is the responsibility of any employee, initiating work involving – and handling of – pressurized equipment, and the obligation of any employee engaging into work involving – and handling of – pressurized equipment, that the required registration(s) of qualification(s) has been made. Employees must also engage actively in the observance of the instructions pt. 1-12 below.
- Pressurized cylinders are not to be transported, handled or left unfastened without valve protection cap firmly attached.
- Pressurized cylinders with valve protection cap may only be left unfastened for a shorter period in relation to what is practically necessary in the process of transportation and handling. At all other times they must be kept in cylinder cages, or fastened with a safety chain or another device preventing them from tipping over.
- In case of emptying, drawing off, or any other process involving opening of a cylinder valve which is not safely attached to a manifold and pipework, the cylinder must unconditionally be fastened in a cylinder cage or a fastening device at least equivalent to a cylinder bracket. If hose(s) exceeding 1 m is used in the process it must be safely fastened in both ends, and safeguarded with a hose safety wire. Only registered hoses with a correct maintenance status may be used .
- Cylinders are not to be lifted or hoisted by using the valve protection cap (applies to open and closed type).
- During transport the ADR rules must be observed.
- Cylinders must be laid parallel to or at right angles to the longitudinal axis of the vehicle or container; however, those situated near the forward transverse wall must be laid at right angles to the said axis. Short cylinders of large diameter (about 30 cm and over) may be stowed longitudinally with their valve-protecting devices directed towards the middle of the vehicle or container. Cylinders which are sufficiently stable or are carried in suitable devices effectively preventing them from overturning may be placed upright. Cylinders which are laid flat must be securely and appropriately wedged, attached or secured so that they cannot shift.
- Cylinders stored in the car/van, e.g. for testing, must be fastened using a device equivalent to a cylinder bracket, and must have the valve protection cap attached.
- During installation of cylinders the valve protection cap may only be removed when a cylinder bracket is attached loosely with the bolt and nut in mesh, or otherwise safeguarded against tipping over. After the correct orientation of the cylinder, for the attachment of the discharge valve, the bracket(s) must be tightened.
- Prior to the opening of any valve, hose(s) must be attached and firmly fastened at the discharge valve(s) and the manifold(s) connected to the same pipework.
- If a cylinder is removed from a system, all cylinder valves must be closed before any hose (attached to the same pipework) is loosened. If the system must be commisioned with missing cylinder(s), the manifold must have blind plug(s) safely fastened in the place of the missing cylinder(s), prior to the opening of any cylinder valve, or the manifold must be equipped with non return valves.
Prior to the loosening or removal of cylinder bracket(s) the discharge valve must be removed and the valve protection cap must be attached.
If the cylinders are installed in a FlexiRack, the cylinder valves must be closed, the cylinders must be equipped with valve protection caps of the open type and the IV20 discharge valve must be secured with a valve outlet safety plug. If the cylinders are not equipped with valve protection caps of the open type, the FlexiRack parts must be dismantled and valve protection caps must be attached. During the assembly of FlexiRack without open valve cap, the valve cap is not to be removed unless the cylinder is secured by FlexiRack beams, and it must be safeguarded that the cylinder cannot move in the direction of the cylinder bottom. The latter sentence also applies to other cylinder installations where the cylinder is not standing on a firm surface (e.g. horizontal installation).
- Cylinders that are not installed in a system, but are used for pressure testing, for example, at the installation site, must be securely fastened prior to the removal of the valve protection cap. If hoses are used the relevant part of pt. 3 above applies.
- During the use of the booster unit, all hoses must be safely attached at both ends, and at all couplings, and must be additionally secured by the hose safety wire along the full length of the hose(s). Cylinders being boosted to and from, must be placed in a cylinder cage or fastened in their brackets.
- Damaged cylinder (with for example corrosion or dents) has to be depressurized asap – safety precaution in pt. 3 must be observed. Futhermore it must be ensured that the cylinder is not exposed to any unnecessary forces (for example transport or temperature) before depressurization.
The Project Manager/Project engineer must, within his geographical area of responsibility, ensure that all contractors have received this instruction (INMON001), in two copies whereof one copy has been returned to Fire Eater duly signed as a commitment that the contractor accepts to carefully follow the instructions pt. 1-12 above at any time. If a signed copy has not been received from a contractor (already registered in NAV) at the latest 6 months after AMIN_Flasker enters into force, the contractor’s account must be closed and no sales or supplies of components intended for pressurization may take place. The account must remain closed untill correction has been made.
It is the duty of the Chief Technician and the Safety at Work Representative, to ensure that all employees of Fire Eater know the presence, contents and implications of this document. This must be included in the introduction programme for new employees, and at the latest 2 months after this document enters into force for existing employees.
The above guidelines must be respected by all employees. Additional requirements and guidelines issued by authorities may be present.
Copies of the present document signed with “accepted, date and signature” of the contractor is inserted in a dedicated loose leaf binder near the desk of Marketing & Business Development. It is stored in this location during the time the contractor is registered with an open account in ERP-systems, whereafter it can be removed.
The Chief Technician or the Safety At Work Representative passes on to the Chief of Administration, the copies of this document signed by each employee as documentation that he/she is aware of the present document. The Chief of Administration files the copies in the employees files.
