fumigazione-ligur-control-genovaWhat is it?

The “fumigation” is an effective procedure against the development of wood pests.

The problem arises (in transport by sea) because the wood is one of the commonly used as packaging materials (crates, pallets, etc.) And present in the container.

The list of countries that adopt this procedure as a standard of quality is constantly growing and in the near future it will lead to the global compliance procedures to ensure that circulating in wood packaging on the planet do not represent a source of risk for the preservation of flora and forests.

In particular for the fumigation means that particular procedure (thermal or chemical), with which it disinfest by parasites, precisely, pallet and timber packages or other wooden structures that will subsequently be shipped or directly before the containers of stowage on board ships in what is called “fumigation QPS” (pre-ships quarantine).

If fumigation QPS above all, the management of the operation is complicated and creates many problems because the required standards vary according to the current regulations in many countries and also as a result of more precise requirements introduced by the port authorities and shipping companies.

In addition, the non-performing of the fumigated containers (minimum ventilation procedure 12 hours), an operation that “cleans” the unit of transport from previously released toxic gas inside and that “certifies” his “non-hazardous”, l ‘ loading and transport of the same is regulated dall’IMDG code (international Regulations for the transport of dangerous goods by sea).

Fumes or Vapors use
 Fumigation is a thermal or chemical treatment which subjects the materials used for packaging
Various treatment
  • Methyl bromide (MB)
  •  Heat treatment (HT)
  • Dielectric heating (DH)
The heat treatment (HT)
Heating of the material, which is brought to a temperature of at least 56 ° C for 30 minutes.

Types of fumigants

Methyl bromide is among the most widely used fumigants and its use has been restricted by the Montreal Protocol for its role in ozone depletion.
Among the fumigants used are:
•    Phosphine
•    1,3-dichloropropene
•    Chloropicrin
•    Methyl isocyanate
•    Hydrogen cyanide
•    Sulfuryl fluoride
•    Formaldehyde
•    Iodoform

The hydrocyanic acid kills every creature that uses oxygen as a source of life and it is of course also deadly to humans. It has a strong, pungent smell that comes close to that of almonds and is used only in special locked or sealed environments, such as the holds of ships and storage warehouses. Chlorine, formaldehyde and chloropicrin are used to destroy the germs carrying diseases. Their smell is easily detectable. Chlorine has limited efficiency while the sulfur dioxide may cause oxidation of the metals and the disintegration of tissues.

Free Estimates

The chemical agent is generally used in the fumigation QPS methyl bromide (a toxic gas) and transactions can only be conducted by firms authorized provided with regular certifications.

The new amendment all’IMDG code (the 35th), a few days ago came into force definitively (01/01/2012), revised by extending and better defining all the regulations governing the transport of fumigated containers by sea.

The procedure provides that, after stopping at least 24 hours, minimum period sufficient to ensure that the gas reaches a uniform concentration in each part of the unit, it is able to board if:

a)     the container is identified as UN 3359 (Units of cargo under fumigation), Class 9;
b)     the container is suitable for fumigation, then have a system for opening doors which allows to reduce to a minimum the toxic gas leakage;
c)     on the doors of the container is placed a warning sign (30 cm x 25 cm) as shown below:
d) the Multimodal dangerous goods form is drawn up indicating all the container data covering its dangerous classification and the same must be attached copy of the fumigation certificate issued by the company in charge of the operation;
e) the same way they are given directions for disposal of the fumigant;
f) handling of the container takes place taking into account the provisions of the IMO document MSC 1 / Circ. 1361 (recommendations on the safe use of pesticides in ships applicable to the fumigation of cargo transport units);
g)  if the container is stowed, on board, under the bridge, is present on the ship a device able to detect the possible fumigant gas leak;
h) in no case is carried out fumigation on board the vessel;
i)  the master of the ship is put always aware in advance of the presence of fumigate units on board (see poster Dangerous Goods);
j) relevant staff must have received appropriate training
