(7) Special Provisions (§172.102)

×Note:
Special provisions may be very complex. The extracts are taken from 49 CFR §172.102. Please be careful with the information, as necessary, additional conditions may be applied that are not written here. Please check the original source and report bugs.

A3	For combination packagings, if glass inner packagings (including ampoules) are used, they must be packed with absorbent material in tightly closed metal receptacles before packing in outer packagings. Browse special provision A3
B47	Each tank may have a reclosing pressure relief device having a start-to-discharge pressure setting of 310 kPa (45 psig). Browse special provision B47
B53	Packagings must be made of either aluminum or steel. Browse special provision B53
T10	see 49 CFR §172.102
TP2	a. The maximum degree of filling must not exceed the degree of filling determined by the following: Where: t_r is the maximum mean bulk temperature during transport, t_f is the temperature in degrees celsius of the liquid during filling, and α is the mean coefficient of cubical expansion of the liquid between the mean temperature of the liquid during filling (t_f) and the maximum mean bulk temperature during transportation (t_r) both in degrees celsius. b. For liquids transported under ambient conditions α may be calculated using the formula: Where: d₁₅ and d₅₀ are the densities (in units of mass per unit volume) of the liquid at 15 °C (59 °F) and 50 °C (122 °F), respectively. Browse special provision TP2
TP12	This material is considered highly corrosive to steel. Browse special provision TP12
TP13	Self-contained breathing apparatus must be provided when this hazardous material is transported by sea. Browse special provision TP13

(8) Packing Authorizations (§173.***)

(8A) Exceptions	None
(8B) Non-bulk	158	see 49 CFR §173.158
(8C) Bulk	243	see 49 CFR §173.243

(9) Quantity Limits

(9A) Passenger aircraft/rail	Forbidden
(9B) Cargo aircraft only	2.5 L

(10) Vessel stowage

(10A) Location

Stowage category “D” means the material must be stowed “on deck only” on a cargo vessel or on a passenger vessel carrying a number of passengers limited to not more than the larger of 25 passengers or one passenger per each 3 m of overall vessel length, but the material is prohibited on a passenger vessel in which the limiting number of passengers is exceeded.

(10B) Other

44	Stow “away from” oxidizers.
66	Stow “separated from” flammable solids.
89	Segregation same as for oxidizers.
90	Stow “separated from” radioactive materials.
110	Packaging Group II if concentration does not exceed 70 percent acid.
111	If concentration exceeds 50 percent acid, notes 66, 74, 89, and 90 apply.

Segregation Chart for Load, Transport, Storage

In this table a statement is contained for each hazard class whether the loading, transport or storage with other hazard classes is allowed, is not permitted or is restricted. The table is based on U.S.-Code 49 CFR §177.848.

Note: In this segregation and separation chart are HazMat of hazard class 8 considered depending if there are liquid. Currently HazMat Tool is not able to to check if a HazMat is liquid or not. Therefore it is assumed as liquid. See PHMSA Interpretation #09-0252.
