PA = Do not load cargo during precipitation, keep dry and close hatches that are not being worked. Loading, including transfer from one
ship to another, during rain or snow is unacceptable. A competent person recognized by the national Administration of the country of
shipment should certify to the ship’s master that the DRI, at the time of loading, is suitable for shipment and does not contain fines more
than 5%. Hot-moulded briquettes should not be loaded if product temperature is in excess of 65 degree C. (The cargo temperature should
be monitored during loading. Protect machinery, accommodation and equipment from dust. During cargo handling "NO SMOKING" signs
are to be posted on decks and in areas adjacent to cargo compartment and no naked lights should be permitted in these spaces."65 C").

PB = (not to be confused with iron sponge, spent) such as lumps, pellets and cold-moulded briquettes. Clean and dry without any residue
of previous cargoes. Do not load cargo during precipitation, keep dry and close hatches that are not being worked. "DRI should not be
loaded if material temperature is in excess of 65C. A competent person recognized by the national Administration of the country of
shipment should certify to the ship’s master that the DRI, at the time of loading, is suitable for shipment. Shippers should certify that the
material conforms to the requirement of this Code. Prior to shipment, DRI should be aged for at least 72 hours, or treated with an air
passivation technique, or some other equivalent method that reduces the reactivity of the material to at least the same level as the aged
product. Hatches should be sealed. All ventilators and other openings should be closed to maintain an inert atmosphere.
Shipper should provide necessary specific instructions for carriage, either:

1. prior to loading, provision should be made to introduce the inert gas at tank top level so that the whole of the stow can be maintained at a
low oxygen level throughout the voyage. Maintenance throughout the voyage of cargo spaces under an inert atmosphere containing less
than 5% oxygen. The hydrogen content of the atmosphere should be maintained at less that 1% by volume; or

2. that the DRI has been manufactured or treated with an oxidation-and corrosion-inhibiting process which has been proved, to the
satisfaction of the competent authority, to provide effective protection against dangerous reaction with seawater or air under shipping
conditions.

Except as provided for under paragraph 2 above, any material which is wet or is known to have been wet should not be accepted for
carriage. The cargo should be loaded, stowed and transported under dry conditions. Protect machinery, accommodation and equipment
from dust."

G = General requirement for carrying Ferrosilicon. Ventilation to be in operation at all times from commencement of loading until the
compartment is free from Ferrosilicon. Fans should be explosion proof. Total ventilation should be at least 6 changes per hour, based on
an empty compartment. All gas measurements to be recorded in log book. Bilge wells should be clean and dry before commencement of
loading. Bilge timbers are to be in good condition and adequately covered. Bilge wells must be opened up and the compartment washed
after unloading. A gas check must be made before washing out begins.  Cargo must be and stay dry. No smoking. No entry in holds prior to
gas contamination check.

P2 = Wooden sweat battens and dunnage should be removed from the cargo space before cargo is loaded.

P3 = Temperature of material should not, at the time of loading, exceed 35 degrees C or 5 degrees C above ambient temperature,
whichever is higher. If temp of material exceeds 55° C and continues to increase, ventilation to the cargo space should be restricted. If self
heating continues, the carbon dioxide or inert gas should be introduced. Readings should be recorded and kept on board.

P4 = Keep cargo dry unless being loaded into a specially constructed or fitted ship.
