SAFETY AND HANDLING
4
WARNING! The design and configuration of the Flush Tank
does not allow its use in potentially explosive atmospheres,
or the pressure and temperature limits described in the
technical specifications of this manual to be exceeded.
Always use liquids and solvents that are compatible with the unit. If in doubt, consult your PMC
Distributor. When working with the Flush Tank, it is recommended that the operator wear suitable
clothing and elements of personal protection, including, without limitation, gloves, protective
goggles, safety footwear, and face masks. Use breathing equipment when working with the Flush
Tank in enclosed spaces or in areas with insufficient ventilation. The introduction and follow-up of
safety measures must not be limited to those described in this manual. Before using the Flush
Tank, a comprehensive analysis must be made of the risks derived from the products to be
dispensed, the type of application, and the working environment.
To prevent possible injury caused by incorrect handling of the raw
materials and solvents used in the process, carefully read the
Material Safety Data Sheet (MSDS) provided by your supplier.
Deal with the waste caused according to current regulations.
To avoid damage caused by the impact of pressurized fluids, do
not open any connection or perform maintenance work on
components subject to pressure until the pressure has been
completely eliminated.
Use suitable protection when operating, maintaining or being
present in the area where the equipment is functioning. This
includes, but is not limited to, the use of protective goggles,
gloves, shoes and safety clothing and breathing equipment.
The equipment includes components that reach high
temperatures and can cause burns. Hot parts of the equipment
must not be handled or touched until they have cooled
completely.
To prevent serious injury through crushing or amputation, do not
work with the equipment without the safety guards installed on
the moving parts. Make sure that all the safety guards are
correctly reinstalled at the end of the repair or maintenance work
of the equipment.
