Hazard

This material possesses a chemical hazard. Some shipments may be subject to oxidation leading to depletion of oxygen and increase of carbon dioxide in cargo and adjacent spaces. With moisture content of 15% or more this cargo has a low fire risk. As the moisture content decreases, the fire risk increases. When dry, woodchips can be easily ignited by external sources; are readily combustible and can ignite by friction. A condition with complete depletion of oxygen may be present in less than 48 hours.

Stowage and segregation

Segregation as for class 4.1 materials.

Hold cleanliness

No special requirements.

Weather precautions

No special requirements.

Loading

Trim in accordance with the relevant provisions required under sections 4 and 5 of this Code.

Precautions

Entry of personnel into cargo and adjacent confined spaces shall not be permitted until tests have been carried out and it has been established that the oxygen level is 20.7%.footnote If this condition is not met, additional ventilation shall be applied to the cargo hold or adjacent enclosed spaces and re-measuring shall be conducted after a suitable interval.

An oxygen meter shall be worn and activated by all crew when entering cargo and adjacent enclosed spaces.

In dry weather, dust which settles on deck will dry out quickly and is easily ignited. Appropriate precautions shall be taken to prevent fire.

Ventilation

Ventilation of enclosed spaces adjacent to a cargo hold before entry may be necessary even if these spaces are apparently sealed from the cargo hold.

Carriage

No special requirements.

Discharge

No special requirements.

Clean-up

No special requirements.

Emergency procedures

Special emergency equipment to be carried
Self-contained breathing apparatus and oxygen meters should be available.
