Enclose or Confined Space Entry Procedure

If any of the conditions that are stated on the permit for entering the space change, or the conditions in the tank are suspected of becoming unsafe after personnel have entered the enclose or confined space, they should be ordered to leave the space immediately and not be permitted to reenter until the situation has been re-evaluated and the safe conditions stated on the enclose or confined space work permit have been restored.

When an accident involving injury to personnel occurs in a dangerous space, the first action must be to raise the alarm. Although speed is often vital in the interests of saving life, rescue
operations should not be attempted until the necessary assistance and equipment has been mustered. There are many examples of lives being lost through hasty, ill-prepared rescue attempts. Prior organisation is of great value in arranging quick and effective response. Lifelines, rescue harness, breathing apparatus, resuscitation equipment and other items of rescue equipment
should always be kept ready for use and a trained emergency team should be available. An agreed means of communication should be agreed in advance.
Whenever it is suspected that an unsafe atmosphere has been a contributory factor to the accident, breathing apparatus and, where practicable, lifelines must be used by persons entering the space.
The officer in charge of a rescue team should remain outside the space, from where the most effective control can be exercised.
It is imperative that every member of the rescue team should know what is expected of him. Regular drills and exercises in rescue from enclosed spaces should be carried out.

Tanker and terminal personnel with safety critical responsibilities should be instructed in resuscitation techniques for the treatment of persons who have been overcome by toxic gases or fumes, or whose breathing has stopped from other causes such as electric shock or drowning.

Most tankers and terminals are provided with special apparatus for use in resuscitation. This apparatus can be of a number of different types. It is important that personnel are aware of its location and
are trained in its proper use. The apparatus should be stowed where
it is easily accessible and not kept locked up. The instructions provided with it should be clearly displayed. The apparatus and the contents of cylinders should be checked periodically. Adequate spare bottles should be carried.

Load Line & Why it is Important

Merchant ships have a marking on their hull know as the Plimsoll line or the Plimsoll mark, which indicates the limit until which ships can be loaded with enough cargo, internationally, the Plimsoll line on a ship is officially referred to as the international load line. Every type of ship has a different level of floating and the Plimsoll line on a ship generally varies from one vessel to another.  All vessels of 24 meters and more are required to have this Load line marking at the centre position of the length of summer load water line. There are two types of Load line markings:- Standard Load Line marking – This is applicable to all types of vessels. Timber Load Line Markings – This is applicable to vessels carrying timber cargo. These marks shall be punched on the surface of the hull making it visible even if the ship side paint fades out. The marks shall again be painted with white or yellow colour on a dark background/black on a light background.  The comp

Difference Between A, B & C-Class Divisions?

IMO Symbol A Class Division  IMO Symbol B Class Division  SOLAS has tables for structural fire protection requirement of bulkheads and decks. The requirements depend on the spaces in question and are different for passenger ships and cargo ships. The Administration has required a test of a prototype bulkhead or deck in accordance with the Fire Test Procedures Code to ensure that it meets the above requirements for integrity and temperature rise. Types of Divisions: "A" Class "B" Class "C" Class "A" Class: "A" class divisions are those divisions formed by bulkheads and decks which comply with the following criteria: They are constructed of steel or equivalent material They are suitably stiffened They are constructed as to be capable of preventing the passage of smoke and flame to the end of the one-hour standard fire test. they are insulated with approved non-combustible materials such that the average tempera

Pump Shaft Alignment Procedure

Types of shaft alignment methods: Visual Line-Up Straightedge/Feeler Gauge Rim and Face Cross Dial Reverse Dial Laser Visual Line-Up The visual line-up method is the most common method of alignment. Used in initial installations, visual line-up allows technicians to analyze the working conditions and feasibility of installation. Straightedge/Feeler Gauge Straightedges are used to determine the offset between coupling halves. Corrections are made under all four of the machines feet. Feeler gauges or taper gauges measure the gap between coupling halves at the bottom and top of the coupling. Rim and Face This method is similar in principle to using a straightedge and feeler gauge, but more accurate since dial indicators are used. The rim reading measures the offset between the coupling halves. The face reading measures the angular difference between the faces of the coupling. Changes are calculated with the same formula as the straightedge/feeler gauge met
