Reconditioned packagings. Reconditioned packagings include:
1. metal drums that:
A. are cleaned to original materials of construction, with all former contents, internal and external corrosion, and external coatings and labels removed;
B. are restored to original shape and contour, with chimes (if any) straightened and sealed, and all non-integral gaskets replaced;
C. are inspected after cleaning but before painting, with rejection of packagings with visible pitting, significant reduction in material thickness, metal fatigue, damaged threads or closures, or other significant defects;
2. plastic drums and jerricans that:
A. are cleaned to original materials of construction, with all former contents, external coatings and labels removed;
B. have all non-integral gaskets replaced;
C. are inspected after cleaning, with rejection of packagings with visible damage such as tears, creases or cracks, or damaged threads or closures, or other significant defects.
Recycled plastics material. Recycled plastics material means material recovered from used industrial packagings that has been cleaned and prepared for processing into new packagings. The specific properties of the recycled material used for production of new packagings should be assured and documented regularly as part of a quality assurance programme recognized by the competent authority. The quality assurance programme should include a record of proper pre-sorting and verification that each batch of recycled plastics material has the proper melt flow rate, density, and tensile yield strength, consistent with that of the design type manufactured from such recycled material. This necessarily includes knowledge about the packaging material from which the recycled plastics have been derived, as well as awareness of the prior contents of those packagings if those prior contents might reduce the capability of new packagings produced using that material. In addition, the packaging manufacturer’s quality assurance programme under 188.8.131.52 of IMDG Code should include performance of the mechanical design type test in 6.1.5 of IMDG Code on packagings manufactured from each batch of recycled plastics material. In this testing, stacking performance may be verified by appropriate dynamic compression testing rather than static load testing.
Remanufactured packagings. Remanufactured packagings include:
1. metal drums:
A. are produced as a UN type from a non-UN type;
B. are converted from one UN type to another UN type; or
C. undergo the replacement of integral structural components (such as non-removable heads); or
2. plastic drums that:
A. are converted form one UN type to another UN type (such as 1H1 to1H2); or
B. undergo the replacement or integral structural components.
Remanufactured drums are subject to the same provisions of IMDG Code that apply to a new drum of the same type.
Respirable size particulates. Particulates in the size range that permits them to penetrate deep into the lungs upon inhalation.
Respirator (approved). A device which has met the requirements of 30 CFR Part 11 and is designed to protect the wearer from inhalation of harmful atmospheres and has been approved by the National Institute for Occupational Safety and Health (NIOSH) and the Mine Safety and Health Administration (MSHA).
Respiratory system. Consists of (in descending order) – the nose, mouth, nasal passages, nasal pharynx, pharynx, larynx, trachea, bronchi, bronchioles, air sacs (alveoli) of the lungs, and muscles of respiration.
Re-used packagings. Re-used packagings means packagings to be refilled which have been examined and found free of defects affecting the ability to withstand the performance tests; the term includes those which are refilled with the same or similar compatible contents and are transported within distribution chains controlled by the consignor of the product.
Road tank vehicle. Road tank vehicle means a vehicle equipped with a tank with a capacity of more than 450 litres, fitted with pressure-relief devices. The tank of a road tank vehicle is attached to the vehicle during normal operations of filling, discharge and transport and is neither filled nor discharged on board. A road tank vehicle is driven on board on its own wheels and is fitted with permanent tie-down attachments for securement on board the ship. Road tank vehicles should comply with the provisions of chapter 6.8 of IMDG Code.
Ro-ro cargo space. Ro-ro cargo space means spaces not normally subdivided in any way and extending to either a substantial length or the entire length of the ship in which goods (packaged or in bulk, in or on rail or road cars, vehicles (including road or rail tankers), trailers, containers, pallets, demountable tanks or in or on similar stowage units or other receptacles) can be loaded and unloaded normally in a horizontal direction.
Ro-ro ship (roll-on/roll-off ship). Ro-ro ship (roll-on/roll-off ship) means a ship which has one or more decks, either closed or open, not normally subdivided in any way and generally running the entire length of the ship, carrying goods which are normally loaded and unloaded in a horizontal direction.
Route of entry. The path by which chemicals can enter the body. There are three main routes of entry: inhalation, ingestion, and skin absorption.
Salvage packagings. Salvage packagings means special packagings conforming to the applicable provisions of IMDG Code into which damaged, defective or leaking dangerous goods packages, or dangerous goods that have spilled or leaked are placed, for the purposes of transport, recovery or disposal.
