CHAPTER 11 SAFETY AT WORK STATIONS

Article 11.01 Dimensions of working spaces

Working spaces shall be large enough to provide every person working at them with adequate freedom of movement.


Article 11.02 Side deck

1. The clear width of the side deck shall be at least 0,60 m.

That figure may be reduced to 0,5 m at certain points that have been designed for safety of operations such as deck-swabbing cocks. It may be reduced to 0,4 m at bollard emplacements.

2. Up to a clear height of 0,90 m above the side deck, the clear width of the side deck may be reduced to 0,54 m provided that the clear width above, between the outer edge of the hull and the inner edge of the hold, is not less than 0,65 m. In this case, the clear width of the side deck may be reduced to 0,50 m if the outer edge of the side deck is fitted with a guard rail in accordance with European Standard EN 711 to prevent falling. On craft 55 m or less in length with only aft accommodation, the guard rail may be dispensed with.

3. The requirements of sections1 and 2 shall apply up to a height of 2.00 m above the side deck.  

4. For vessels under 24m in length or designed for operation on narrow canals, where it is not possible to comply with the requirements of paragraphs 1 to 3 above, alternative measures shall be taken to ensure safe means of access to all working decks.


Article 11.03 Access to working spaces

1. Points of access and passageways for the movement of persons and objects shall be of sufficient size and so arranged that:

   (a) in front of the access opening, there is sufficient room not to impede movement;

   (b) the clear width of the passageway shall be appropriate for the intended use of the working space and shall be not less than 0,60 m, except in the case of craft less than 8 m wide, where it may be reduced to 0,50 m;

   (c) the combined height of the passageway and the coaming is not less than 1,90 m.

2. Doors shall be so arranged that they can be opened and closed safely from either side. They shall be protected against accidental opening or closing.

3. Stairs, ladders or steps shall be installed in accesses, exits and passageways where there is more than a 0,50 m difference in floor level.

4. Working spaces which are manned continuously shall be fitted with stairs if there is a difference in floor level of more than one metre. This requirement shall not apply to emergency exits.

5. Craft equipped with holds shall have at least two movable hold ladders which can be used to enter and leave the hold in complete safety. Ladders should have a positive means of fixing when in use. This requirement shall not apply where an equivalent ladder is fixed permanently in each hold.  

6. A safe means of access to the vessel shall be provided. Gangways shall comply with EN526.


Article 11.04 Exits and emergency exits

       - the fire goes out,

       - the supply of combustion air is no longer adequate,

       - the heated air exceeds a previously set temperature, or

       - the electricity supply is no longer reaching the safety devices.

In the above cases the fuel supply shall not be reestablished automatically after being cut off.

(d) It shall be possible to switch off the combustion air and heating air blowers from outside the areas to be heated.

(e) Where heating air is drawn from outside, the intake vents shall as far as possible be located well above the deck. They shall be installed in such a manner that rain and spray cannot get in.
