Safety

Instrument Symbols

The following labels are displayed on the Discovery DSC™system for your protection:

Please heed the warning labels and take the necessary precautions when dealing with those parts of the

instrument. The Discovery DSC Getting Started Guide contains cautions and warnings that must be

followed for your own safety.

WARNING: The operator of this instrument is advised that if the equipment is used in a manner

not specified in this manual, the protection provided by the equipment may be impaired.

AVERTISSEMENT: L'utilisateur de cet instrument est prévenu qu'en cas d'utilisation contraire

aux indications du manuel, la protection offerte par l'équipement peut être altérée.

Symbol Explanation

This symbol indicates that you should read this Getting Started Guide for impor-

tant safety information. This guide contains important warnings and cautions

related to the installation, operation, and safety of the Discovery DSC system.

If you are not trained in electrical procedures, do not remove the cabinet covers

unless specifically instructed to do so in the manual. Maintenance and repair of

internal parts must be performed only by TA Instruments or other qualified

service personnel.

Ce symbole indique que vous devez lire entièrement ce guide de démarrage

pour obtenir d'importantes informations relatives à sécurité. Ce guide contient

d'importants avertissements et mises en garde relatifs à l'installation, à l'utilisa-

tion et à la sécurité du système Discovery DSC.

Si vous n'êtes pas formé aux procédures électriques, ne déposez pas les couver-

cles de l'armoire sauf indications spécifiques contenues dans le manuel. La

maintenance et la réparation des pièces internes doivent être effectuées unique-

ment par TA Instruments ou tout autre personnel d'entretien qualifié.

This symbol indicates that a hot surface may be present. Take care not to touch

this area or allow any material that may melt or burn come in contact with this

hot surface.

Ce symbole indique la présence possible d'une surface chaude. Prenez soin de

ne pas toucher cette zone ou de laisser un matériau susceptible de fondre ou de

brûler entrer en contact avec cette surface chaude.

Discovery DSC™ Getting Started Guide Page 6

Electrical Safety

You must unplug the instrument before doing any maintenance or repair work; voltages as high as

120/240 VAC are present in the instrument.

Handling Liquid Nitrogen

Some of the cooling accessories use the cryogenic (low-temperature) agent, liquid nitrogen, for cooling.

Because of its low temperature (–196°C [–321°F)]), liquid nitrogen will burn the skin. When you work

with liquid nitrogen, use the following precautions:

1Wear goggles or a face shield, gloves large enough to be removed easily, and a rubber apron. For extra

protection, wear high-topped, sturdy shoes, and leave your pant legs outside the tops.

2Transfertheliquidslowlytopreventthermalshocktotheequipment.Usecontainersthathavesatisfactory

low-temperature properties. Ensure that closed containers have vents to relieve pressure.

3The purity of liquid nitrogen decreases when exposed to air. If the liquid in a container has been open

to the atmosphere for a prolonged period, analyze the remaining liquid before using it for any purpose

where high oxygen content could be dangerous.

DANGER: Risk of electric shock. High voltages are present in this instrument. Maintenance and

repair of internal parts must be performed only by TA Instruments or other qualified service per-

sonnel.

DANGER: Risque de choc électrique. Présence de tensions élevées dans cet instrument. La

maintenance et la réparation des pièces internes doivent être effectuées uniquement par TA

Instruments ou tout autre personnel d'entretien qualifié.

WARNING: Protective earthing is provided through the mains power cord. Use of a grounded

mains power outlet is required.

AVERTISSEMENT: Mise à la terre de protection est assurée par le cordon d'alimentation secteur.

Utilisation d'une prise d'alimentation secteur terre est nécessaire.

WARNING: Liquid nitrogen boils rapidly when exposed to room temperature. Be certain that

areas where liquid nitrogen is used are well ventilated to prevent displacement of oxygen in the

air.

AVERTISSEMENT: L'azote liquide bout rapidement lorsqu'il est exposé à la température ambi-

ante. Assurez-vous que les zones où l'azote liquide est utilisé sont bien aérées pour éviter le

déplacement de l'oxygène dans l'air.

Thermal Safety

Chemical Safety

DANGER: The cell surfaces can be hot enough to burn the skin during a sample run. If you are

conducting a subambient test on the DSC, cold could also cause injury. After running any type

of experiment, you must allow the DSC cell to return to room temperature before you touch the

inner cell surfaces.

DANGER: Les surfaces de cellule peuvent être assez chaudes pour vous brûler la peau pendant

l'analyse d'un échantillon. Si vous effectuez un essai à basse température sur le DSC, le froid

peut également provoquer des blessures. Après avoir effectué un type d'expérience quel-

conque, vous devez laisser la cellule DSC revenir à la température ambiante avant de toucher

les surfaces internes de la cellule.

WARNING: Do not use hydrogen or any other explosive gas in the DSC.

AVERTISSEMENT: N'utilisez pas d'hydrogène ou tout autre gaz explosif dans le DSC.

WARNING: Oxygen can be used as a purge gas in the DSC. However, the cell must be kept clean

so that volatile hydrocarbons, which might combust, are removed. Maximum pressure for oxy-

gen shall be no greater than 34 kPa gauge (5 psig).

AVERTISSEMENT: L'oxygène peut être utilisé comme gaz de drainage dans le DSC. Toutefois la

cellule doit rester propre pour que les hydrocarbures volatils, qui peuvent brûler, soient élimi-

nés. Pression maximale d'oxygène ne doit pas être supérieure à 34 kPa (5 psig).

WARNING: If you are routinely evaluating materials in the DSC that lose a large amount of vola-

tile hydrocarbons (e.g., lubricating oils), clean the DSC cell more frequently to prevent danger-

ous buildup of debris in the furnace.

AVERTISSEMENT: Si vous évaluez systématiquement les équipements du DSC qui perdent une

grande quantité d'hydrocarbures volatils (p.ex., les huiles de graissage), nettoyez la cellule du

DSC plus souvent pour éviter l'accumulation dangereuse des débris dans le four.

WARNING: If you are using samples that may emit harmful gases, vent the gases by placing the

instrument near an exhaust.

AVERTISSEMENT: Si vous utilisez des échantillons qui émettent des gaz nocifs, ventilez les gaz

en plaçant l'instrument près d'un échappement.

Laser Safety

This instrument is a Class 1 Laser product. Do not stare into the beam. Exempt laser product.

Class 1 Laser Products are accompanied by the following label:

This product complies with IEC 60825-1, with FDA performance standards for laser products.

21 CRF 1040.10 except for deviation pursuant to Laser Notice No.50.

Lifting the Instrument

The Discovery DSC™ is a fairly heavy instrument. In order to avoid injury, particularly to the back, please

follow this advice:

WARNING: Use two people to lift and/or carry the instrument. The instrument is too heavy for

one person to handle safely.

AVERTISSEMENT: Demandez à deux personnes de soulever et/ou de porter l'instrument.

L'instrument est trop lourd pour qu'une seule personne le manipule en toute sécurité.
