I.2Storage Tanks, Containers or Receivers

Storage tanks, containers or receivers with a total internal (geometric) volume greater than 0.1 m³ (100 l) where all surfaces that come in direct contact with the chemical(s) are made from the following materials:
(a) nickel or alloys with more than 40% nickel by weight;
(b) alloys with more than 25% nickel and 20% chromium by weight;
(c) fluoropolymers (polymeric or elastomeric materials with more than 35% fluorine by weight);
(d) glass or glass-lined (including vitrified or enamelled coating);
(e) tantalum or tantalum alloys;
(f) titanium or titanium alloys;
(g) zirconium or zirconium alloys; or
(h) niobium (columbium) or niobium alloys.
Prefabricated repair assemblies and their specially designed components, that:
i. are designed for mechanical attachment to glass-lined storage tanks, containers or receivers that meet the parameters above; and,
ii. have metallic surfaces that come in direct contact with the chemical(s) which are made from tantalum or tantalum alloys.
