What is the frequency of hyper mist system maintenance?

Every 6 month, each visible and audible alarm to be checked. Visible and audible alarms are: Mist operation in local alarm device. Pre warning and mist operation in main control panel.

How often must fixed co2 fire extinguisher system be inspected?

Provided that annual visual inspections are carried out and recorded, all cylinders are to be hydraulically tested after twenty (20) years from the date of manufacture, and every five (5) years thereafter.

What is a high expansion foam system?

High Expansion foam concentrates are low energy foaming agents designed for use with corresponding high expansion foam generators. ... High expansion foam systems can be used for protection of LNG storage areas by quickly blanketing the flammable liquid surface and helping to control vapor release.

How long the records of tests and inspections of a cargo vessel fire extinguishing systems shall be kept on board?

Two-year testing and inspections

Two-year inspections must be carried out to ensure that the indicated actions are taken for the specified equipment. blow dry compressed air or nitrogen through the discharge piping or otherwise confirm the pipe work and nozzles are clear of any obstructions.

What are the conditions that must be maintained at all times to ensure hyper mist system is on standby mode?

The following conditions must be maintained at all times to ensure hyper mist system is on stand by for operation: Sufficient water level must be retained in the fresh water tank. Make sure the power supply is available. The fire alarm system must be in operation.

What is 6 year fire extinguisher maintenance?

6 year maintenance is required for all extinguishers which are subject to the 12 year hydrostatic test. This includes most stored-pressure extinguishers which can be recharged. If the extinguisher passes the six year inspection, a label needs to be affixed to the unit stating that the extinguisher has been inspected.

How often should fire extinguishers be maintained?

All fire extinguishers shall be maintained at intervals not more than one year apart or when an inspection indicates a fire extinguisher is in need of maintenance.

What is the difference between low expansion foam and high expansion foam?

LOW EXPANSION FOAM: Foam aerated to an expansion ratio of between 2 to 1 and 20 to 1. MEDIUM EXPANSION FOAM: Expansion ratio between 20 to 1 and 200 to 1. HIGH EXPANSION FOAM: Expansion ratio above 200 to 1. ... From the above, it becomes obvious that a 3% foam concentrate is twice as concentrated as a 6% foam concentrate.

What is the difference between high expansion and low expansion foam?

High Expansion foam has two components stored in separate tanks until mixed at the time of spraying. After spraying, it typically cures in less than 2 minutes. Low expansion spray foam comes in a single tank or container, and relies on moisture in the air to cure, usually in about 20 minutes.

Does high expansion foam contain Pfas?

Protein Foam was produced without using PFAS. High-Expansion Foam is used in fighting Class-A, Class-B, and LNG fires both indoors and outdoors. ... The PFAS chemicals are not PFOA or PFOS. However, in earlier fluoroprotein foams, PFOA and PFOS may have been present in low levels.

Who is responsible for the maintenance of all safety equipment on board the ship?

Every ship appoints a ship safety officer to handle important safety issues related to the ship and the crew. The safety officer acts as the safety advisor on board ships and ensures that all requirements related to health and safety are met.

What is the range of expansion ratio for high expansion foam?

High-expansion foams are those that expand in ratios of over 100:1. Most systems produce expansion ratios of from 400:1 to 1000:1.

What is fire fighting maintenance?

Maintenance involves checking and looking after your fire safety equipment, so that it continues to work for as long as possible and without needing repairs. Depending on the type of fire safety equipment, it might be cleaned, adjusted and lubricated, or wear parts might be replaced, for example.
