CANISTER SHIPMENT
Use this information to prepare a set of filled and
capped canisters for shipment to a customer.
WARNING: 200-liter canisters are very heavy
and should only be moved by trained personnel
using proper equipment. See Moving the
Canisters, page 10, for instructions and
mandatory safety procedures.
NOTE: Ensure the cap on the top of the closure is tight
before shipping a canister filled with chemical. Do not drop
filled canisters or place filled canisters on their side. Both
actions can cause damage to the liners and the breakseals.
1. Palletize canisters with closures up.
2. Do not ship canisters lying on side.
3. Use slip-sheet between layers.
4. Stacking two layers high is permissible for canisters
smaller than 200-liters.
5. Stretch wrap and band pallet for stability.

NOTE: End users should return empty canisters to the
chemical supplier in a similar manner. Be sure to orient
closures up to avoid leakage of any residual chemical into
the area between the shipping cap and closure base.
