2.4 SAFETY INSTRUCTIONS
Non-observance of the most elementary care and safety precautions is almost
always the main cause of industrial injuries.
- Read this Guide carefully before starting up, operating and carrying out maintenance opera-
tions on the system;
- Use the machine within the established limits defined for its technical performance;
- All operating and maintenance operations must be carried out by qualified personnel, accor-
ding to the regulations concerning industrial accidents, although not specifically mentioned in
the Guide;
- Always keep the system’s signals and protections against accidents in good condition; if they
areremoved duringmaintenance operations,they mustbe restoredbefore starting thesystem
again;
- Do not open the covers and guards while the system is in operation;
- Do not wear rings, wristwatches, jewellery and loose clothing which could get entangled in
the moving parts; it is advisable to wear suitable clothing to prevent accidents. Always follow
the safety instructions applicable;
- Do not tamper with the safety devices installed on the system;
- Cleanthe machine coversand control panelsusing asoft cloth soakedin amildcleaning solu-
tion; do not use solvents such as alcohol or petrol as this may damage the system‘s surfaces.
- Keep all-round the machine clean to avoid falling or sliding.
- Do not use the system if it is damaged; inform the person in charge of maintenance regarding
functioning faults;
- Do not carry out any operation without previous authorisation and do not allow unauthorised
persons to handle the system;
- Disconnect the powersupply beforecarrying outany maintenanceoperations onthe electrical
components;
- The control board must always be kept closed;
- Do not open the tank lid during the distillation cycle: you run the risk of being splashed with
toxic gaseous substances at very high temperatures;
- Always wear gloves to protect the hands, a mask to avoid inhaling toxic substances and
goggles for protecting the eyes, when loading or unloading the tank;
- Do not wear clothing that may cause electrostatic charges as this may lead to the solvent
fumes catching fire;
- Do not smoke or use a naked flame near the machine while the machine is being used or
while maintenance or other operations are being carried out .
- In the event of the system catching fire, disconnect the power supply immediately and put out
the fire using a dust or CO2fire extinguisher. Do not use water.
- Pregnant women or people that have Pace Maker are not allowed to work with the reclaimer.
- Do not use cellular phones near the reclaimer.

2.5 DANGEROUS CHEMICAL REACTIONS
The operator must have sufficient knowledge of the solvent‘s characte-
ristics and reactions, the dangers it can provoke and the precautions to
be taken. This information is contained in the technical and safety data
sheet which must be supplied together with the solvent.
It is advisable to keep the solvent data sheets ( together with this Guide
if possible) within easy reach, ready for rapid consultation.
Onlyinflammablesolvents belonging toexplosive groups IIAand IIB and
with self-ignition higher than 250°C can be reclaimed.
The operator runs the risk of being exposed to dangerous chemical reac-
tions if unsuitable solvents are introduced into the reclaimer.
2.5.1 PEROXIDES
It is essential to avoid any reaction due to the presence of peroxides which may be formed in
the absence of stabilisers and in the presence of oxygen. Solvents such as:
Tetrahydrofuran (or THF or Tetramethylene Oxide, or 1.4 -Epoxybutane )
Diethyl Ether ( or Ethyl Ether , or Ether or Ether Oxide or Common Ether )
Disopropyl Ether ( or Isopropyl Ether, or DIPE )
1.4 Dioxane ( or Dioxane, or p-Dioxane or Diethylene Oxide )
Ethyl Cellosolve ( or Ethylene glycol-Monoethyl Ether, or 2-Etoxyethanol )Alcohol oxides and
Ketones
Butyl Cellosolve ( or Ethylene glycol-Monobutyl Etherem or 2-Butoxyethanol )
The person who uses the solvents mentioned above must be aware of the
possibilityof formationof peroxidesin theabsence ofstabilisers, asdanger
from these solvents is not restricted to the distillation process alone, but is
also present during handling phases (storage, operation, etc. ).
The safety data sheet of such solvents must contain all the necessary
information regarding formation of peroxides and the precautions to be
taken (stabilisers, type, quantity and analysis methods).

16
GENERAL INFORMATION
2
2.5.2 NITRIC SUBSTANCES AND NITRATES
It is forbidden to use the system with substances and solvents which may cause reactions due
to the heating of nitric substances (Nitromethane, Aromatic nitrates) and nitrates (Nitric Acid
Ester) as there is risk of explosion.
2.5.3 NITROCELLULOSE
Specialcare must beexercised inthecase ofsolvents contaminatedwithNitro-
cellulose as a residual component, as in some types of ink or paint. The safety
data sheets of products containing Nitrocellulose (paints, ink or other products)
must indicate the contents.
Forreclaiming solvents containingNitrocellulose contactI.S.T.AfterSales Service andtake into
consideration the following points:
- never allow the temperature to exceed 120°C while heating the diathermic oil;
If the reclaimer is NOT arranged beforehand with nitricellulose kit: keep the
reclaimer in an area away from the production area, from operating stations and
otherinstallations, preferablyin theopen, whileensuringadequateprotectionagainst
atmospheric conditions.
- never set the thermostats in such a manner as to cause drying of the residue;
- in the event of long term storage of cleaning solutions, there is a possibility of formation of
peroxides. Therefore it is necessary to check the solution to detect the presence of peroxides
before starting the distillation process. If they are present, appropriate steps must be adopted
for their elimination ( for example, by adjusting the pH to an alkaline value);
Only for NOT continuous cycle models: unload the distillation residue at the
end of each operating cycle in order to avoid build-up of residual sludge containing
Nitrocellulose,since, thehigher theconcentration, thegreater isthe riskof dangerous
conditions.
- special care must be taken while disposing of distillation residue sludge containing Nitrocellu-
lose. Use metallic containers with lids and dilute with a small amount of water to prevent the
sludge from drying up completely (as this condition favours the self-ignition of Nitrocellulose).
2.5.4 EXOTHERMIC REACTIONS
Avoid recovery of solvents or mixtures and pollutants which may produce exothermic reactions
(reactions followed by development of uncontrolled heat).
Read the safety chart concerned carefully.

17
GENERAL INFORMATION

2.5.5 PRECAUTIONS AGAINST ELECTROSTATIC CHARGES
- The operator must not use clothing which could provoke electrostatic charges (for example,
clothes made of synthetic fibres).
- Clean the tank and other parts of the system using a slightly damp cloth (not made of synthetic
fibres).
- Ensure that the power supply system is equipped with a suitable earth lead.
2.5.6 SPILL
Any leakage of contaminated solvent or reclame solvent around the reclaimer
must be removed immediately following the instructions on the safety data
sheet of the solvent (SECTION 6- MEASURES IN CASE OF ACCIDENTAL
SPILLAGE)
