TRANS/WP.15/AC.2/2001/1 page 14 281 301 (1) In paragraph (1) insert a new paragraph before the last sentence, to read: “The measurements may only be made by persons wearing protective breathing equipment suited to the goods carried.” 291 301 (1) In paragraph (1) insert a new paragraph before the last sentence, to read: “The measurements may only be made by persons wearing protective breathing equipment suited to the goods carried.” 311 210 (2) Amend to read: “(2) The lower edges of door-openings in the sidewalls of superstructures and the coaming of access hatches to under-deck spaces shall have a height of not less than 0.50 m above the deck. (...) ” (9) Replace with paragraphs (9) to (11) as follows: “(9) Where services spaces are located in the cargo area under deck, they shall be arranged so as to be easily accessible to permit persons even when wearing protective clothing and breathing apparatus to operate easily the equipment contained therein. (...) The dimensions of openings, except for those of wing tanks and double bottoms not having a wall common to the cargo tanks, shall be sufficient to allow a person wearing breathing apparatus to enter or leave the space without difficulties.

Breathing equipment could be stored either at the nearest fire station or secured in the tunnel. (...) Given the specialist nature of storage, inspection and maintenance, it is recommended that the breathing apparatus should be stored by the fire service where it would be convenient for training. The standard breathing apparatus must have capacity to allow breathing for 30 minutes at the minimum, and its required endurance will depend in part on the distance between intervention shafts or TRANS/AC.9/9 page 24 protected cross passages and in part on the activity or heat stress involved.

- intrinsically safe apparatus; - flameproof enclosure apparatus; - apparatus protected by pressurization; - powder filling apparatus; - apparatus protected by encapsulation; - increased safety apparatus. (...) Electrical apparatus protected against water jets means an electrical apparatus so designed that water, projected by a nozzle on the enclosure from any direction, has no damaging effects. (...) MISCELLANEOUS Battery of receptacles (battery of tanks) */ means an assembly of several receptacles with a capacity not less than 100 litres and not more than 1 000 litres, or tanks with a capacity of not less than 1 m3, interconnected by a manifold and permanently mounted in a frame. Breathing apparatus (self-contained) means an apparatus which supplies the person wearing it when working in a dangerous atmosphere with breathing air by means of pressurized air carried with him or by means of a tube.

This device shall be so designed that such measurements are possible without the necessity of entering the spaces to be checked. 7.2.3 General service requirements 7.2.3.1.6 Entry into empty cargo tanks, the residual cargo tanks, the cargo pump-rooms below deck, cofferdams, double-hull spaces, double bottoms, hold spaces or other confined spaces is only permitted if: • The concentration of flammable gases and vapours given off by the cargo in the cargo tanks, the residual cargo tanks, the cargo pump-rooms below deck, cofferdams, double-hull spaces, double bottoms, hold spaces or other confined spaces, is below 10 % of the LEL, the concentration of toxic gases and vapours given off by the cargo is below national accepted exposure levels, and the percentage of oxygen is between 20 and 23.5 vol %, or • The concentration of flammable gases and vapours given off by the cargo in the cargo tanks, the residual cargo tank, the cargo pump-rooms below deck, cofferdams, double-hull spaces, double bottoms, hold spaces or other confined spaces, is below 10 % of the LEL, and the person entering the spaces wears a self-contained breathing apparatus and other necessary protective and rescue equipment, and is secured by a line. (...) In case of emergency or mechanical problems, it is allowed to enter the tank when the gas concentration of flammable gases and vapours given off by cargo is between 10 and 50% of the LEL. The breathing apparatus (self- contained) in use has to be designed in such a way that the causing of sparks is avoided.

Full face-mask air-purifying and air-supplying respirators except those used in breathing apparatus for firefighters 2. Additional chemicals suitable for decontamination of chemical warfare agents: • Diethylenetriamine (111-40-0) 3.

It is proposed to add a new entry to Table A for UN 3077 which would allow the carriage in bulk as indicated in column 8. A breathing apparatus would be made compulsary as indicated in column 9.

The proposal to authorize bulk transport of soluble lead compounds (UN No. 2291) in double hull vessels with the use of breathing apparatus was adopted (see annex I). 30. (...)

The testing of such a large volume of a potentially self-heating substance requires that special precautionary measures be put in place, for example: (a) an environmental impact study carried out to ensure that the test apparatus is set up in an area where gases emitted in the event of a fire will not pollute populated areas; (b) fire fighting equipment installed and the Fire Brigade notified; (c) a control room should be available on the test site to provide protection against the elements to operators and the temperature control and recording instrumentation; GE.05-23040 ST/SG/AC.10/C.3/2005/47 page 2 (d) all safety operating points clearly marked so as to be visible in the dark by torchlight; and (e) vehicles parked ready for escape if necessary. (...) Line the ditch with a suitable material to render it impervious. 4.4 Place a wooden pallet in the centre of the oven floor for the test specimen to be located on during the test. 4.5 Provide each operator with personal protective clothing as per the manufacturer’s Safety Data Sheet and provide each person handling the test material with a respirator with two chemical filters for the filling operation of the specimen container and self-contained breathing apparatus in case a fire occurs and the wind blows towards the control room.

This transmission or teaching may be dispensed internally by the personnel. 1.3.2.2.4 Read: “1.3.2.2.4 Persons wearing self-contained breathing apparatus shall be physically able to bear the additional constraints. (...) Practice: - cleaning of cargo tanks, e.g. degassing, washing, residues, cargo residues - sampling - danger of explosion - health risks - gas concentration measures, e.g. which apparatus to use and how to use it - monitoring of closed spaces and entry to these spaces - certificates for degassing and permitted work - degree of filling and over-filling - safety installations - pumps and compressors. Emergency measures - physical injury, e.g. liquefied gases on the skin, breathing in gas, assistance irregularities relating to the cargo, e.g. leak in a connection, over-filling, polymerization and hazards in the vicinity of the vessel.
