WBGT

According to the American Conference of Governmental Industrial Hygienists (ACGIH), the Wet Bulb Globe Temperature (WBGT) can be a useful, first-order index of the environmental contribution to heat stress. It is influenced by air temperature, radiant heat, and humidity. WBGT is a weighted sum of DRY BULB, WET BULB and VERNON GLOBE temperatures.

•Dry Bulb Temperature (DB) - provides a measure of simple “ambient temperature.”

•Wet Bulb Temperature (WB) -provides a measure of evaporative cooling including effects of airspeed and humidity. WB is always lower than DB.

•VERNON (6" black) GLOBE Temperature (GT) - provides a measure of radiant heat load including air speed effects.

Note: The 3M™ Heat Stress Monitor’s Mini Globe is a Vernon Globe equivalent MINI GLOBE provides gt where gt = 2/3 GT + 1/3 DB. The above temperatures (GT, WB, DB) are summed to generated WBGT as follows:

WHERE GT = 6" VERNON GLOBE WHERE gt = 1.63" MINI GLOBE

With Direct Exposure to Sunlight

WBGTout = 0.7 WB + 0.2 GT + 0.1 DB = 0.7 WB + 0.3 gt Without Direct Exposure to the Sun

WBGTin = 0.7 WB + 0.3 GT = 0.7 WB + 0.45 gt – 0.15 DB

Note: For more information on using WBGT reading in the assessment of both heat stress and strain when evaluating the risk to worker safety and health, the American Conference of Governmental Industrial Hygienists Thermal Stress TLV should be consulted.

SETUP

Sensor Installation

Remove the WIBGET monitor and its Dry Bulb, Wet Bulb and Globe sensors from the carrying case. Holding each sensor in turn by its connector plug, align it vertically and rotationally with its receptacle (as indicated by symbols on top of the unit), then push it firmly into place. An audible ‘click’ indicates full engagement.

CAUTION

Do not twist sensors once inserted into the base unit. Doing so may damage the sensor or sensor connector.

Wet Bulb Preparation

The Wet Bulb sensor requires careful attention to help maintain accuracy. The wick (or sock) must be replaced at the first sign of discoloration, stiffness or poor wetting (see MAINTENANCE section). Fill the reservoir and wet the wick using distilled (or demineralized) water. A bottle and demineralizer are provided with the instrument. The Wet Bulb reservoir may be filled, without impacting instrument readings, by adding room temperature water to the sponge (not to the wick). Refilling is normally required daily. Conditions of low humidity, high temperature or high air speed may require more frequent refilling.

CAUTION

The wet bulb wick must remain wet during operation to help maintain the accuracy of the sensor.

Location and Environment

For optimum accuracy the sensors should be positioned in an open space and approximately three to six feet (one to two meters) above the floor or ground within the work area. When radiant loading is high {GT = DB + 20 °C (68 °F)}, careful consideration must be given to shielding the Dry Bulb sensor.

Note: For additional information and guidance on assessing heat stress in the work environment consult the American Conference of Government Industrial Hygienists – Thermal Stress TLV’s.

CAUTION

Keep all connectors clean and dry. If a connector becomes wet, it must be thoroughly dried prior to instrument usage. Condition of the sensor receptacles may be tested by removing all sensors, turning the unit on and checking that all functions read 0.0 ± 0.3°C or 32.0 ± 0.5°F. If these are not the readings, do not use until the reason has been determined and corrected.

Do not expose dry bulb (DB) to temperatures above 65°C (150°F). This may damage the base unit. To monitor environments above 65°C (150°F), use a remote sensor set accessory and relocate the base unit to a cooler area.

To enter Data Log Mode and save previous data logging sessions already in memory:

1.After turning the instrument on, press and hold VIEW, then press SELECT, then release both. The display will show “AP.” (APPEND).

2.To append (add) data to that already in memory, press SELECT again. The time interval from the previous data logging session will be displayed.

3.If desired, the time interval may be changed at this time by pressing VIEW (time base) to select a different time interval. Time intervals available are 0.5, 1.0, 2.0, 5.0, 6.0, 10.0, 20.0, and 30.0 minutes.

4.Press SELECT again to resume data logging without erasing any previous records stored in memory.

To enter Log Mode and erase all previous data logging sessions in memory:

1.Press and hold VIEW, then press SELECT, then release both. The display will show “AP.” (APPEND).

2.Choose a time interval by pressing VIEW (time base) until the desired time interval is displayed. Refer to step 3. above for available time intervals.

3.Press SELECT to begin data logging and erase all previous data logging sessions in memory.

Note: The WIBGET monitor resets itself to monitor mode when the memory is full.

Demand Logging

Pressing SELECT at any time during data logging will cause the immediate addition in memory of a data set other than those data sets logged at the preselected time interval. This feature is useful if an unusual event occurs at a time other than at the preselected time intervals. As an example, if data logging is occurring at 30 minute time intervals, and an unusual event occurs 14 minutes after the last 30 minute logging, pressing SELECT will capture that event in memory 14 minutes after the last 30 minute logging has occurred without affecting the pre selected 30 minute time interval.

To perform Demand Data Logging only:

1.Press and hold VIEW, then press SELECT, then release both. The display will show “AP.” (APPEND).

2.Press View until the display shows “.0”.

3.Pressing SELECT at any time will immediately add a data set in memory with time noted. Since no time interval has been selected, data logging occurs only when SELECT is pressed.

MAINTENANCE

WARNING

Wet Bulb

Operation of the Wet Bulb with a fouled wick (e.g. discolored, stiff or will not wet) may lead to errant (high) readings.

Wick Replacement

To replace a fouled wick, pull it and its sponge straight upward over the sensor. Slide a new proper fitting 3M wick over the sensor such that it is snug over the tip and reaches the bottom of the reservoir. To prevent water spillage, a snug fitting 3M sponge should be placed over the wick encased sensor and positioned in the mouth of the reservoir. Dampening the sponge and wick facilitates removal and replacement.

Water Treatment

For maximum accuracy and extended wick life, distilled water should be used (available from most pharmacies). Alternately, demineralized tap water may be used. Be sure to follow instructions supplied with the demineralizer carefully.

Cleaning

CAUTION

Avoid the use of harsh cleaning materials, abrasives and other organic solvents. Such materials may permanently scratch the surfaces and damage the display window, labels, or monitor housing.

To clean external surfaces, use a soft wipe/tissue dampened with a mild detergent in warm water solution.

Storage

Remove each sensor by pulling straight up (DO NOT TWIST) on its connector collar. Empty the Wet Bulb reservoir and squeeze excess water from its sponge. Return all items to their proper location in the carrying case.

BATTERY

WARNING

Battery must be replaced in a non-hazardous area only. Battery replacement is not an intrinsically safe operation. Use only approved battery. Failure to do so may result in sickness or death.

CAUTION

Observe proper polarity when inserting the battery. Polarity is marked on the inside of the battery compartment.

This instrument may contain a nickel metal hydride (NiMH) battery. Dispose of battery in accordance with local regulations.

The WIBGET monitor is powered by a rechargeable 9v (8.4v) Ni-MH battery and comes with an external charger. In addition the WIBGET monitor can operate on a nonrechargeable 9v alkaline battery or the charger (AC adapter).

Charging

When the battery nears full discharge, “LOBAT” appears in the upper right-hand corner of the display. For continued/continuous operation or to simply recharge the battery, connect the charger via its receptacle (12vdc) located on the lower left side of the monitor. Recharging requires a minimum of 12 hours. Although Ni-MH batteries may be recharged many times, they eventually degrade, requiring replacement.

Replacement

With the power ‘OFF’, remove all four screws from the rear case and open the instrument. Noting the battery’s location, replace it. Reinstall the rear case using the reverse process.

CALIBRATION

The WIBGET monitor base unit and all three sensors can be returned to 3M for calibration to NIST standards. A CERTIFICATE OF INSTRUMENT CALIBRATION will be issued only if the WIBGET base unit along with all three of its sensors have passed calibration. Traceable certification and before/after data can also be provided at an additional cost. It is recommended that the WIBGET monitor be calibrated yearly.

Liste des mises en garde et des avertissements énoncés dans les présentes Directives d’utilisation

MISE EN GARDE

Ce moniteur aide à mesurer certains facteurs environnementaux qui peuvent contribuer au stress thermique. Une mauvaise utilisation peut provoquer des problèmes de santé ou la mort. Pour tout renseignement sur l‘utilisation adéquate de ce produit, consulter son superviseur, lire les Directives d‘utilisation ou communiquer, au Canada, avec le Service technique au 1 800 267 4414.

Chaque utilisateur de ce matériel doit lire et comprendre les présentes Directives d‘utilisation. L‘utilisation de ce matériel par des personnes qui n’ont pas reçu la formation nécessaire ou qui n’ont pas les qualifications requises, ou l’utilisation non conforme aux présentes Directives d’utilisation, peut nuire au bon fonctionnement du produit et provoquer des problèmes de santé ou la mort.

N’utiliser ces capteurs et cet instrument que pour la surveillance des facteurs environnementaux pour lesquels ils sont conçus. Tout manquement à ces directives peut nuire au bon fonctionnement du produit et provoquer des problèmes de santé ou la mort. Pour tout renseignement sur l‘utilisation adéquate de ce produit, consulter son superviseur, lire les Directives d‘utilisation ou communiquer, au Canada, avec le Service technique au 1 800 267 4414.

Chaque fois que l’appareil est mis sous tension, ce dernier effectue un auto-test. En cas d’échec de l’auto-test ou d’affichage d’un code d’erreur, ne pas utiliser cet appareil. Cela risque de nuire au bon fonctionnement du produit et provoquer des problèmes de santé ou la mort.

Le port de sortie de données en série RSS-214DL RS 232 ne doit être utilisé que dans un endroit non dangereux. L’utilisation du port de sortie des données n’est pas une opération intrinsèquement sécuritaire. Tout manquement à ces directives peut provoquer des problèmes de santé ou la mort.

Ne jamais modifier cet instrument. La substitution de composants risque de compromettre la sécurité intrinsèque. Cela risque de nuire au bon fonctionnement du produit et provoquer des problèmes de santé ou la mort.

Ne réparer l’instrument et n’en remplacer les composants qu‘avec des composants 3M approuvés pour l‘appareil. Tout manquement à ces directives peut nuire au bon fonctionnement du produit et provoquer des problèmes de santé ou la mort.

Ne remplacer la pile que dans un endroit non dangereux. Le remplacement de la pile n’est pas une opération intrinsèquement sécuritaire. N’utiliser que des piles approuvées. Tout manquement à ces directives peut provoquer des problèmes de santé ou la mort.

Ne recharger l’instrument que dans des zones sans danger à l’aide d’un bloc d’alimentation 3M (adaptateur c.a.). Le chargement et le fonctionnement de piles au moyen d’un adaptateur c.a. ne sont pas des opérations intrinsèquement sécuritaires. Ne pas tenter de recharger des piles alcalines. Cela risque de nuire au bon fonctionnement du produit et provoquer des problèmes de santé ou la mort.

AVERTISSEMENT

Ne pas tordre les capteurs une fois que ceux-ci sont insérés dans l’unité principale. Cela risque d’endommager le capteur ou son connecteur. Pour aider à maintenir l’exactitude du capteur, la mèche du réservoir humide doit rester humide pendant le fonctionnement de l’instrument.

Conserver tous les connecteurs propres et secs. Si un connecteur devient humide, il doit être séché à fond avant l’utilisation de l’instrument. L’état des compartiments des capteurs peut être vérifié en retirant tous les capteurs, en mettant l’appareil sous tension, puis en examinant si toutes les fonctions indiquent 0,0 ± 0,3 °C or 32,0 ± 0,5 °F. Si les lectures sont différentes, alors ne pas utiliser l’instrument jusqu’à ce que la cause soit déterminée et corrigée.

Ne pas exposer le réservoir sec à des températures supérieures à 65 °C (150 °F). Cela risque d’endommager l’unité principale. Pour surveiller les environnements dont la température est supérieure à 65 °C (150 °F), utiliser un accessoire doté d’un capteur à distance et déplacer l’unité principale dans un endroit plus frais.

Éviter d’utiliser des agents de nettoyage forts, des abrasifs et d’autres solvants organiques. De tels produits peuvent égratigner les surfaces de façon permanente et endommager la fenêtre d’affichage, les étiquettes ou le boîtier du moniteur.

Insérer la pile selon la polarité appropriée. La polarité est indiquée à l’intérieur du compartiment de la pile.

Cet instrument peut contenir une pile à hydrure métallique de nickel (NiMh). Mettre la pile au rebut conformément aux règlements locaux.

DIRECTIVES ET LIMITES D‘UTILISATION

Important

Avant d‘utiliser cet instrument, chaque utilisateur doit lire et comprendre les présentes Directives d‘utilisation. Conserver ces Directives d‘utilisation à titre de référence.

Description générale

Les présentes Directives d’utilisation s’appliquent au moniteur de stress thermique RSS-214 WIBGET de 3M™. Cet instrument est un thermomètre globe mouillé portatif doté d’un microprocesseur, conçu pour mesurer certains facteurs environnementaux qui peuvent contribuer au stress thermique. Un microprocesseur interne commande les indications et les réponses aux signaux reçus par les capteurs fixés sur le dessus de l’appareil. Lorsqu’il est sous tension, il surveille de façon continue l’air ambiant.

Le moniteur WIBGET est alimenté par une pile rechargeable à hydrure métallique de nickel (NiMh) de 9 volts ou une pile alcaline non rechargeable de 9 volts. Il est conçu pour être intrinsèquement sécuritaire lorsqu’il est alimenté par des piles. Le moniteur WIBGET est homologué intrinsèquement sécuritaire par la CSA pour les endroits dangereux de classe 1, division I, groupes A, B, C et D.

Les composants du moniteur WIBGET sont montés dans un boîtier en plastique de 12,2 x 6,9 x 3,6 cm - haut./larg./prof. (3,75 x 6,2 x 1,75 po - haut./larg./prof.) (Fig. 1). L’écran (ACL) et les touches de fonctions (FUNCTION) et de sélections (SELECT) se trouvent sur la face avant de l’appareil. L’interrupteur On/Off, la sortie des données analogiques et la prise du chargeur se trouvent sur le côté gauche de l’appareil. Sur le dessus de l’appareil se trouvent les broches de connecteur des capteurs du globe, du réservoir sec et du réservoir humide. Une étiquette sur laquelle figurent l’information en matière de sécurité intrinsèque et le numéro de série se trouve à l’arrière de l’appareil.
