Please observe the following general safety instructions:
The information in these instructions will help you to work in a safe and
contamination-free manner.
Please read these instructions with particular care before working in the safety
weighing enclosure for the first time.
Keep the instructions handy. When working on the ST1 weighing enclosure, ensure
that the instructions are also available there. a1-envirosciences recommends creating
an SOP for working on the ST1 weighing enclosure.
These instructions assume that the user is familiar with all relevant directives, the
regulations "Safe working in laboratories" and working on technical equipment.
The ST1 weighing enclosure may only be operated by trained personnel with the
necessary basic technical knowledge.
Personnel must be properly instructed and trained before working with hazardous
substances.
The applicable safety regulations of your company have priority and must be complied
with at all costs.
Work according to the work regulations given in the operating instructions. For your
own safety and for the protection of other employees, you must observe the
additional safety instructions given in these instructions in addition to the safety
regulations applicable to you.
For any questions regarding the use of the ST1 safety weighing enclosure, always
contact the person responsible for it or a1-envirosciences.
Safety instructions for installation, operation, modification and malfunctions
There is an immediate danger to life in case of contact with live parts. If the
insulation is damaged, switch off the power supply immediately and arrange
for repair. Work on the electrical equipment should only be carried out by
trained, authorised personnel. Keep moisture away from live parts. This could
lead to a short circuit.

Basically, the discharge electrodes are safe to touch. This means that touching the metal
tips of the discharge electrodes will not cause electric shock.
Substances as well as auxiliary and operating materials could cause damage
to health or the environment in the event of contact.
Before starting any work with the equipment, observe the relevant work
instructions of the operator.
Observe the safety data sheets of the substances used.
Remember that the transfer of hazardous substances from the storage
location to the equipment and the disposal of contaminated waste also
involve risks.
Wear required protective equipment (PPE = personal protective equipment).
Solvents can form explosive vapour/air mixtures. Dusts can form explosive
dust/air mixtures. An explosive atmosphere in conjunction with an ignition
source can lead to an explosion.
Solvents are highly flammable. Storage of flammable solvents in the
equipment is therefore not permitted.
Explosions or fires can lead to serious or fatal injuries.
The equipment must not be used when the filter unit is switched off.
Flammable liquid or gaseous substances must not be introduced into the
work area, except for the approved cleaning agents and solvents.
Ignition sources must not be present in or brought into the work area during
cleaning.
Dust formation in explosive concentrations in the work area must be
avoided.

If mains switches are not accessible, the equipment cannot be switched off
quickly and safely when needed. Damage to the equipment is possible, or
other hazards may arise.
Make sure that the mains switches are always freely accessible.
Highly variable or excessive ambient temperatures can cause condensation of
water in the filter unit or overheating.
Operate the ST1 safety weighing enclosure at as constant an ambient
temperature as possible in the range of 5 to 40°C to avoid damage from
condensing water or overheating.
Improper maintenance, repair or modification work can lead to considerable
damage.
Cleaning, assembly, disassembly, maintenance, adjustment and repair may
only be carried out by persons who are trained for these activities and who
know the possible dangers.
Unauthorised modifications and alterations to the ST1 safety weighing
enclosure are not permitted for safety reasons.
Only original parts and accessories specifically designed for the ST1 safety
weighing enclosure may be used. Any liability for damage caused by the use
of non-original parts or accessories is excluded.
