2  Safety

2 Safety

This chapter points out the safety concept of the instrument and contains general rules of behavior and warnings from hazards concerning the use of the product.

The safety of users and personnel can only be ensured if these safety instructions and the safetyrelated warnings in the individual chapters are strictly observed and followed. Therefore, the manual must always be available to all persons performing the tasks described herein.

2..1 User qualification

The instrument may only be used by laboratory personnel and other persons who on account of training or professional experience have an overview of the dangers which can develop when operating the instrument.

Personnel without this training or persons who are currently being trained require careful instruction. The present Operation Manual serves as the basis for this.

2..2 Proper use

The instrument has been designed and built for laboratories. It serves for the distillation of steam-vola- tile substances.

2..3 Improper use

Applications not mentioned above are improper. Also, applications which do not comply with the technical data are considered improper.

The operator bears the sole risk for any damages caused by such improper use. The following uses are expressly forbidden:

•Use of the instrument in rooms which require ex-protected instruments.

•Use on samples, which can explode or inflame (e.g. explosives, etc.) due to shock, friction, heat or spark formation.

2..4 Warning notices used in this manual

WARNING

Generally, the triangular warning symbol indicates the possibility of personal injury or even loss of life if the instructions are not followed.

WARNING

Hot surface.

WARNING

Electrical hazard.

WARNING

Caustic substances.

ATTENTION

With the general „Read this” symbol, ATTENTIONs indicate the possibility of equipment damage, malfunctions or incorrect process results, if instructions are not followed.

NOTE

Useful tips for the easy operation of the instrument.

2..5 Product safety

The instrument is designed and built in accordance with state-of-the-art technology. Nevertheless, risks to users, property, and the environment can arise when the instrument is used carelessly or improperly.

The manufacturer has determined residual dangers emanating from the instrument

•if the instrument is operated by insufficiently trained personnel.

•if the instrument is not operated according to its proper use.

Appropriate warnings in this manual serve to make the user alert to these residual dangers.

2..5..1 Instrument-related hazards

Pay attention to the following safety notices:

WARNING

Potential implosion risk if used with damaged glassware.

• Beware of damaged or cracked glass parts.

WARNING

Potentially hot surfaces during operation (surfare temperatures at times exceed 60 °C) and hot steam passing off the waste outlet.

• Always be aware of the risk of being burned.

WARNING

Potentially lethal voltage inside the instrument.

•Do not remove covers and other parts protecting from electricity.

•Always keep the areas of electric parts, such as power supply plug, mains switch, etc. dry.

2  Safety

2..5..2 Other hazards

WARNING

Certain solvents in or in the vicinity of the instrument can form peroxides and/or are highly inflammable.

•Always be aware of the explosion risk when working with hazardous substances or with substances of unknown composition.

•Always provide a good ventilation within or in the vicinity of the system.

2..5..3 Safety measures

WARNING

Sodium hydroxide, acids and lye are used for applications according to Kjeldahl. For this reason, protective goggles must be worn at all times when using the instrument or working in its immediate proximity.

2..5..4 Safety elements

The instrument is provided with the following safety elements:

•Protective door: Safety appliance to protect users from burns at the splash protector (distillation area), which is hot during distillation.

•Protective door sensor: Prevents the start of a distillation with the protective door open and stops a running distillation and the dosing of reagents immediately when the protective door is opened during the process.

•Sample tube sensor: Prevents the start of a distillation without a sample tube inserted.

•Protective shield (cover) at condenser: Protection of glass parts.

•Service door sensor/switch: Electrical power is disconnected immediately when the service door is opened, thus preventing electrical shock during maintenance.
