2.3 Hazardous GassesWhen hazardous gases (such as poisonous, flammable, or oxygen depleting) are potentiallypresent in or around the Maxum II area, all national and international safety requirements mustbe fulfilled to protect personnel and the environment against hazards that could arise. Allprocess conditions (such as normal, backup, and upset) must be considered in thedetermination for potential hazardous gas presence.Scheduled preventive maintenance and inspection for leaks should be performed by thecustomer. Minimize leak sources by external venting of the oven exhaust and analyzer vents.This reduces but does not eliminate the sources for leaks, so personnel protection is arequirement whenever hazardous/poisonous gases may be present. Disregarding this warningcould result in serious injury or death and damage to equipment.2.4 LocationEach Maxum II is manufactured and tagged for a specific hazardous area classification. Eachunit must be installed in an area that is suitable for this area classification.WARNINGT-RatingEach unit is tagged with a T-rating which quantifies the maximum surface temperature thatmay occur in the instrument. The user must ensure that no combustible gas concentrationswill be present, whether on a continual or occasional basis, which has an ignition temperaturebelow the T-rating of the unit.The analyzer house should be located as close as possible to where the sample is to beobtained to minimize the sample transit time. It is preferable that this distance be less than 30m (100 feet).The analyzer house must be large enough to allow ample access for installing, operating, andmaintaining the analyzer. The concrete slab for the analyzer house should be large enough toaccommodate gas cylinders located on the outside. Make sure to secure the cylinders using acylinder rack or chain guard.Space inside for the analyzer must be at least 229 cm high by 127 cm wide by 102 cm deep (90”high by 50” wide by 40” deep). The height may be somewhat less if there is no sampling systemcabinet or panel beneath the analyzer, or if the analyzer is a Maxum II Modular Oven.
