The Draeger Tube measurement system provides an easy method for testing containers and other spaces for the presence of fumigation agents. A specially developed measuring strategy allows for the detection of fumigants eve when the chemical is unknown. The Draeger Fumigation Test Kit can be equipped with all the necessary components for this measurement.

Hazards caused by fumigants - To prevent goods from being damaged by animals such as insects and other disease carriers, containers are flooded with toxic or suffocating gases. Fumigants are highly toxic and harmful to the health in many ways. To ensure adequate protection, the concentration of the fumigants used must be measured. This is relevant for all personnel present during:

• the start or finish of the fumigation process
• the opening of transport containers or other confined spaces
• the loading or unloading of fumigated products from transport containers
• the removal of fumigated goods from packaging materials
• transportation (in case of leakages)

Suitable measurement instruments are used to determine the type and concentration of fumigants before opening a container or entering other spaces.

Thereby, it is important to check the Oxygen concentration in the container or other spaces. When inert gases have been used, they will displace Oxygen and this results in a very high probability of suffocation. A leakage in one individual package is one example of a relatively simple cause for this.

Mobile and quick - The well known Draeger Tube measuring method is an easy way to perform measurements. In only a few minutes, the concentration of the fumigants within the container can be determined. Depending on the concentration measured, the decision can be made whether the container or space can be entered or ventilated.

Even when a container has not been declared correctly or the labeling is no longer legible, the Draeger measuring strategy will assist in the identification and detection of the fumigation agents.

Easy to use - For several decades, Draeger Tubes have been renowned for their ease of use and high degree of measurement accuracy. Even without special training, the Draeger Tubes, which were especially developed for this application, provide reliable test results. Draeger Tubes are ready for use at any time. All that is needed are the corresponding tubes, the Draeger Accuro hand pump and the Draeger bar probe. By comparing the color change within the detector tube to the printed scale, an estimation of the concentration can be made.

Recommended measurement strategy - If the fumigant is known, the corresponding Draeger Tube is chosen and the measurement carried out as instructed. If the measurement result is too high, then the container or space should be ventilated. A new measurement should be taken at periodic intervals and when the concentration is low enough, the container or room can be released for entry. If the concentration detected is below the defined maximum limit, the container or room can be opened and entered.

The measurement of fumigants should take place while the container is still closed. To do this, insert the Draeger Bar Probe through the rubber sea of the container door. The probe should be used to lift the rubber seal of the container at its lowest point and pushed as far as possible into the container. The Draeger Tubes should then be prepared for measurement and attached to the bar probe. The necessary pump strokes for the measurement should then be made by using the Draeger gas detection pump.

If the fumigant is not known, the use of the Draeger Simultest Fumigation is recommended to determine which chemical has been used. This test set allows for the measurement of five typical fumigation agents at the same time.

• Ammonia or Ethylene Oxide
• Methyl Bromide
• Hydrocyanic Acid
• Phosphine
• Formaldehyde

In addition, the following Draeger Tubes should be used for the measurement of Ethylene Oxide, carbon Dioxide and Sulfuryl Fluoride:

• Ethylene Oxide 1/a, 1 to 15 ppm
• Carbon Dioxide 0.1%/a, 0.1 to 1.2 vol %
• Sulfuryl Fluoride 1/a, 1 to 5 ppm

When one or more gases are present, the container or space should be ventilated with air before entry and individual Draeger Tubes used to test the concentration of the corresponding gases periodically.
