2 Contact Insecticides in a Cargo Space

  2.1 Fast-acting insecticides for space application, e.g., against flying insects:

  • .1 Pyrethrins (with or without synergist);

  • .2 Bioresmethrin; and

  • .3 Dichlorvos.

  2.2 Slower-acting residual insecticides for surface application:

  • .1 Malathion (premium grade);

  • .2 Bromophos

  • .3 Carbaryl;

  • .4 Fenitrothion;

  • .5 Chlorpyriphos-methyl; and

  • .6 Pirimiphos-methyl.

3 Contact Insecticides and Baits in Accommodation

  3.1 Fast-acting insecticides for space application, e.g., against flying insects:

  • .1 Pyrethrins (with or without synergist);

  • .2 Bioresmethrin; and

  • .3 Dichlorvos.

  3.2 Slower-acting residual insecticides:

  • .1 Malathion (premium grade);

  • .2 Diazinon;

  • .3 Fenitrothion;

  • .4 Propoxur;

  • .5 Bendiocarb; and

  • .6 Permethrin.

  3.3 Insecticides for use against particular pests and as an additional treatment:

  • .1 Diazinon, as an aerosol spray or lacquer against ants, cockroaches and flies;

  • .2 Dieldrin and Aldrin, in lacquers for control of ants and cockroaches;

  • .3 Methoprene bait, for control of Pharaoh's ants; and

  • .4 Chlorpyriphos-ethyl, as a bait and as a lacquer.

4 Rodenticides

  4.1 Chronic poisons in baits:

  • .1 Calciferol; and

  • .2 Any Anticoagulant in the following two classes:

    • .2.1 Hydroxycoumarins (e.g., Warfarin, Fumarin, Coumatetralyl, Difenacoum, Brodifacoum); and

    • .2.2 Indandiones (e.g., Pival, Diphacinone, Chlorophacinone).

  4.2 Acute poisons in baits or liquids:

TO BE USED ONLY IN PORT AND BY QUALIFIED OPERATORS

  • .1 Barium fluoroacetate;

  • .2 Fluoroacetamide;

  • .3 Sodium fluoroacetate; and

  • .4 Zinc phosphide.

5 Fumigants

 TO BE APPLIED ONLY BY QUALIFIED OPERATORS

Additional information on methyl bromide and phosphine (hydrogen phosphide) to be read in conjunction with 3.1.3.

  5.1 Fumigants against insects in empty cargo spaces and against rodents anywhere aboard ship:

  • Carbon dioxide

  • Nitrogen

  • Methyl bromide and carbon dioxide mixture

  • Methyl bromide

  • Hydrogen cyanide

  • Phosphine (Hydrogen phosphide)

  5.2 Fumigants against insects in loaded or partially loaded cargo spaces and cargo transport units:

Refer to MSC.1/Circ.1264 and MSC.1/Circ.1265

CARE IS NEEDED IN SELECTING TYPES AND AMOUNTS OF FUMIGANTS FOR TREATMENT OF PARTICULAR COMMODITIES

  • .1 Carbon dioxide;

  • .2 Nitrogen;

  • .3 Methyl bromide and carbon dioxide mixture;

  • .4 Methyl bromide; and

  • .5 Phosphine (Hydrogen phosphide).

Methyl bromide

 Methyl bromide is used in situations where a rapid treatment of spaces or commodities is required. Fumigation with methyl bromide should be permitted only when the ship is in the confines of a port (either at anchor or alongside) and to disinfest the spaces after the crew members have disembarked (see 3.1.3.3). Prior to re-embarkation of the crew, ventilation of the treated spaces should be completed and a gas-free certificate should be issued as described in 3.1.4 before personnel are permitted to enter.

Phosphine (Hydrogen phosphide)

 A variety of phosphine-generating formulations are used for at-berth fumigations and also for in-ship in-transit fumigations. Application methods vary widely and include surface only treatment, probing, perforated tubing laid at the bottom of spaces, recirculation systems and gas-injection systems or their combinations. Ventilation of the treated spaces should be completed and a gas-free certificate should be issued as described in 3.1.4 before personnel are permitted to enter. All safety recommendations related to the fumigation of cargo in cargo holds under in-ship in-transit fumigation are laid down in MSC.1/Circ.1264 .
