SAFETY REGULATIONS

Earthing of the Equipment

Due to flow rate of the liquid at the high spraying pressure the

electro-static charge may be developed on the spraying gun under

certain circumstances. It may result in sparks of flames due to

discharging. To prevent this phenomena the spraying device must be

earthed. In addition the conductive connection (potential equalizing

cable) must be installed between the high-pressure device and the

gun during processing of the materials with the ignition point below

21°C (NITRO etc.).

Resistance to Pressure

All elements forming part of the high-pressure section of the

automatic spraying gun comply by their operating pressure with the

maximum pressure specified by the technical parameters.

Manipulation with High-Pressure Valve

The high-pressure gun operates with very high pressures.

Therefore never put your hand and/or fingers before the gun and

never focus the gun to the body. During assembly or disassembly of

the nozzle, resp. during cleaning or during any interruption of the

work proceed very carefully and secure the gun to prevent accidental

start (disconnection of the control air). This is to prevent accidental

start of the gun and possible subsequent injury.

Injury of Operator

The injury caused by the high-pressure liquid may be very serious.

In case of injury immediately seek the doctor and notify him/her on

type of material causing the injury.

Personal Protection at Work

During spraying and handling with the application materials, as

well as during cleaning of the equipment adhere to instructions of

manufacturers of the materials; use suitable personal protective

equipments (clothes, gloves, respirators, protection masks, resp.

breathing devices, protecting creams etc.) to protect the skin and

respiration tracts.

Although very small amount of fog is generated during the high-

pressure spraying, the spraying procedure cannot be considered for

the fog-free one. Even if the air contains very low number of the

particles, it is necessary to exhaust the solvent vapours, which are

especially dangerous.

Equipment Cleaning

During cleaning of the equipment with the flammable liquids it is

necessary to prevent the back-spraying into the closed vessel, as the

liquid stream can produce the explosive mixture of the gas and air.
