2 Safety
2.1 General matters
The operating manual is an essential part of the Atmos. The operator must ensure that the operating personnel take
note of these guidelines.
The operating manual is likely to be exposed to intensive use at the location where the Atmos is used, so it is the
operator’s responsibility to:
•keep the original in a safe place,
•ensure that a copy of the operating manual is always available at the Atmos workstation,
•ensure that every user reads the operating manual carefully and observes and complies with all information.
The operating manual must be supplemented by its operator to include operating instructions based on existing
national regulations for accident prevention (BGV D27) and environmental protection, including information on
supervisory and reporting obligations, to consider special operational features e. g. with regard to work organization,
work processes and appointed personnel.
In addition to the operating manual and the obligatory accident prevention regulations applicable in the country/place
of use, the recognized technical rules for safe and professional work must also be observed.
The Atmos must be tested by an expert no later than aer one year of use. The test certificate must be documented in
writing.
The operator/user must not make any changes, additions or modifications to the Atmos that could impair its safety
without the manufacturer’s approval. This applies especially to the installation and setting of safety features.
Any spare parts used must meet the technical requirements specified by the manufacturer. This is always warranted
with original spare parts.
Use only trained or instructed personnel. The responsibilities of the personnel for operation, maintenance and repair
must be clearly defined.
Persons who are yet to be trained, instructed or are in the course of general training may only work on the Atmos under
the constant supervision of an experienced person.
The Atmos must only be maintained by specially trained personnel from Trotec Laser GmbH or an authorized service
company.
2.2 Instruction and training
As an operator of the Atmos, you are obliged to inform or instruct the operating/maintenance personnel on existing
legal and accident prevention regulations as well as existing safety devices on and around the Atmos. The various
professional qualifications of the employees must be taken into account.
The operating/maintenance personnel must have understood the instructions and it is necessary to ensure that the
instructions are complied with.
6

Safety
That is the only way to ensure that your personnel work in a safety and hazard-conscious manner. As the operator, you
should therefore have every employee confirm their participation in the briefings in writing.
2.3 Duty to notify
FOR YOUR SAFETY
As the operator of the Atmos, please be sure to observe the information in the CE manufacturer’s declaration, CE
Conformity Declaration and the user information, in particular the operating and maintenance instructions.
RESIDUAL RISK
Filter systems contain combustible components (filter material, seals, plastic parts, etc.). In your workplace evaluation,
in accordance with the Employee Protection Act (AschG), the residual risk of a fire must be taken into consideration. It’s
important that changes in the use of the exhaust system are approved by us in writing.
CE CONFORMITY
As a rule, we will supply you with a filter system with a CE Conformity Declaration. Assembly with other machines
creates a higher-level system for which you, as the operator, must conduct a risk analysis and establish overall
conformity.
DUTY TO NOTIFY
Sparks, cigarette butts and the like must not get into the filter system.
Our systems may only be used for the specified, intended use. Changes in the use require our explicit written approval.
Any use of the system that goes beyond this is considered improper, the manufacturer/supplier cannot be held liable for
any resulting damage. The operator bears the risk.
INTENDED USE OF THE ATMOS
The introduction of dust types or media which do not correspond to those specified in chapter 2.4 are not permitted.
The media intended for the exhaust system or filtration must not be classified in any dust explosion class.
STARTUP, MAINTENANCE AND SERVICING
Information on maintenance and safety can be found in the specific operating instructions. The machine/facility
may only be serviced, repaired or started when it is stationary (all-pole disconnection using the main switch) and by
appropriately trained and authorized personnel.
The Atmos must be checked at least 1x per year in accordance with Section 32 1-4 GKV.(Statutory Health Insurance)
2.4 Intended use
The Atmos by Trotec Laser GmbH is used exclusively as an exhaust system for gases and smoke contaminated with
pollutants that occur in the following areas of activity:
•Stamp production,
•Sign making and engraving work.
7

Safety
We recommend using the H14 filter unit for the following applications:
•Special substances (metal alloys of particle size < 1 μm)
OR
•due to labor law regulations.
For areas of activity other than those mentioned in this operating manual, no statements can be made regarding the risk
to people and the environment. If gases and smoke contaminated with pollutants are to be extracted in an environment
other than that mentioned here, no general statement can be made regarding the suitability of the Atmos.
In this case, it is essential to contact Trotec Laser GmbH, otherwise any guarantee and warranty claims are void.
When handling hazardous substances, please make sure to observe the accident prevention regulations and in
particular the safety regulations for air pollution control systems at the workplace, ZH 1/140.
The Atmos may only be operated with the accessories/equipment provided and approved for this purpose by Trotec

2.8 Notes on special types of hazard
ELECTRICAL POWER
Work on the electrical equipment of the Atmos must only be performed by a qualified electrician or by instructed
personnel under the guidance and supervision of a qualified electrician in accordance with electrotechnical rules.
Aer switching off the system, always wait five minutes so that the built-in capacitors in the control system can
discharge. The casing may only be opened aer this time period has elapsed.
If the power supply cable of this machine is damaged, the machine must not be put into operation. Replace the power
supply cable immediately in order to avoid hazards (spare part number in the appendix).
Use only original fuses with the specified amperage.
Never do any work on live parts.
When executing repairs, make sure that the design features are not changed in a way that reduces safety, in particular,
creepage distances and clearances must not be reduced by insulation.
The proper grounding of the electrical system must be ensured by a protective conductor system.
In the event of malfunctions in the electrical power supply, immediately disconnect the Atmos from the power supply
by:
•switching off the Atmos using the on/off switch and then
•removing the plug of the power cable from the Atmos IEC connector.
DUSTS AND OTHER CHEMICAL SUBSTANCES
With the Amos exhaust system, sometimes toxic dusts are filtered out of polluted air. Depending on the materials used,
these dusts may be hazardous to health or even carcinogenic.
Particular caution must be exercised when handling toxic dusts.
When handling chemical substances, the applicable regulations and the manufacturer’s safety data sheets for these
substances must be observed and complied with in regard to storage, handling, use and disposal. In the event that
dusts from the filters or the exhaust hose come into contact with the eyes or skin, the affected area must be rinsed
immediately with plenty of water. Suitable equipment (eye wash bottles, sink, shower) must be available in the
proximity of the workstation.
11

Safety
Skin contaminated with cleaning agents or disinfectants should be treated aer washing. The prophylactic use of
skin protection products and appropriate skin care can help avoid skin damage. The skin care products used should
be chosen based on the pollutant load and the individual skin type. Primarily, fatty skin care products should be
considered.
Eating, drinking, smoking and storing food in rooms in which there are chemicals is prohibited.
Never store hazardous substances in containers intended for food. Always use containers approved for the respective
substance and label them clearly.
Particle and gas filters are subject to the Ordinance on Hazardous Waste and must be disposed of accordingly
depending on the pollutant load. The improper replacement of the polluted filter inserts represents a health risk for the
people performing this work and their surroundings. It is therefore essential to observe the "Maintenance" section in this
operating manual when replacing the filters.
NOISE
The A-weighted equivalent continuous sound pressure level on the operator workstation of the Atmos is below 68 dB(A)
during normal operation.
Depending on local conditions, the sound pressure level in the vicinity of the Atmos may be higher. This increased
sound pressure level can be caused by neighboring machines and may cause hearing loss.
