GAS DETECTION PUMP

Fumigation is an important market for gas detectiontubes since more than 20 years

New fumigants coming up in the last 5 years because:

•Phase Out of Methyl Bromide by the UN (Montreal protocol)

•Increasing Resistances against Phosphine



STATUS OF FUMIGATION

Phase Out of Methyl Bromide by the UN is the start forinventing a big variety of new fumigants



STATUS OF FUMIGATIONSEGMENTS OF FUMIGATION

Agricultural: Post Harvest Fumigation (PH3)




Agricultural: Preplant Soil Fumigation (Methyl Bromide)




Architecture: Structural fumigation of houses and churches for pest control (Methyl Bromide, will be replaced by i.e. Sulfuryl Fluoride)



STATUS OF FUMIGATIONSEGMENTS OF FUMIGATIONTransport/Quarantine: Fumigations of Containers (different fumigants)




Transport/Quarantine/quality: Fumigations of Containers (different fumigants)Fumigation of bulk ships (PH3)Fumigation of wood packaging material (Methyl Bromide)Fumigation of warehouses



NEW REGULATIONS

New important issues were set up for achievingglobal transport and global trade:

• Eurep Gapstandards and procedures for the global certification of Good Agricultural Practices

• IPPC– ISPM 15



WOOD PACKAGING MATERIAL

IPPC International plant protection convention

is attached directly to the UNO, 132 states have ratified this contract since 2004

www.ippc.int

ISPM 15 International Standard for Phytosanitary Measures (ISPM 15)



ISPM !%

The compliance with ISPM 15 standards is tied into 2 types of treatment:

§ Heating Treatment (HT): dunnageshould be treated at a minimum temperature of 56° C for at least 30 minutes.

§ Methyl Bromide (MB) Fumigation: dunnage must be fumigated with Methyl Bromide

NOTE: ISPM 15 refer to all types of wood from coniferous wood to hardwood



ISPM 15



STATUS OF FUMIGATION

• This leads to an increase in fumigated containers worldwide

• It has to be fumigated with Methyl Bromide, which should be prohibited (at the moment no other gas is recommended)



Exposure Limits OSHA PEL 20 ppm, 80 mg/m³ACGIH TLV: 1 ppm TWANIOSH IDLH: 250 ppm

METHYL BROMIDE



METHYLBROMIDE

• Methyl Bromide 0.2/a 0.2 - 8 ppm • Methyl Bromide 0.5/a 0,5 - 30 ppm • Methyl Bromide 3/a 3 - 100 ppm • Methyl Bromide 5/b 5 - 50 ppm• Petroleum Hydrocarbons 100/a 500 - 2,500 ppm



SO2F2 AS A SUCCESSOR OF METHYL BROMIDE

• Exposure Limits • OSHA 5 ppm, 20 mg/m3 TWA • (ACGIH) TLV: 5 ppm, 21 mg/m3 TWA

10 ppm, 42 mg/m3 STEL • NIOSH 5 ppm, 20 mg/m3 TWA

10 ppm, 40 mg/m3 STEL IDLH 200 ppm

• LEL: Noncombustible Liquid



SO2F2 AS A SUCCESSOR OF METHYL BROMIDE

• Odorless Gas• Very toxic• In use since 1950• 3 production places worldwide• Sold by

and Solvay



New Tube Sulphuryl Fluoride 1/a

•Detection limit: 0.8 ppm (!!!)•Scale: 1,3,5 ppm•Part number: 8103471First tube in this detection range, replaces the old tubeCheapest detection system for Sulfuryl Fluoride

NEW TUBESSULPHURYL FLUORIDE 1/A



• NIOSH 0.1 ppm (0.7 mg/m3) TWA • OSHA PEL: 0.1 ppm (0.7 mg/m3) TWA • Original IDLH: 4 ppm • LEL: Noncombustible Liquid • Description of Substance:

– Colorless to faint-yellow– oil liquid– intensely irritating odor.

CHLOROPICRIN AS A SUCCESSOR OF METHYL BROMIDE



New Tube Chloropicrin 0,1/a

•Detection limit: 0,1 ppm•Range: 0,1-2 ppm•Part number: 8103421

•Chloropicrin is one of the recommended successors for Methyl Bromide•Already in use as an odorant for Methyl Bromide and Sulfuryl Fluoride

NEW TUBESCHLOROPICRIN 1/a



PHOSPHINE

A large range of tubes are offered for different applications:

Phosphine 0.01/a 0.1 - 1 ppmPhosphine 0.1/a 0.1 - 4 ppm Phosphine 0.1/b 1 - 15 ppmPhosphine 1/a 1 - 100 ppm Phosphine 25/a 25 -10,000 ppmPhosphine 50/a 50 - 1,000 ppm

PhosphineCurrent TLV = 0.3 ppm, 1ppm STELLab Range = 0.3 ppm – 3.5 ppmIDLH = 200 ppm

Problem:

Resistances are coming up

More and more insect are notaffectable with phosphine



GASES WORLDWIDE ON TEST

• Ethyl Formate• Ethylen Dibromide• Dinitrile• Carbonylsulfide• MITC• More will follow…………………..
