Paint finish resistant to sea air
Risk of explosion as a result of processes with high levels of electrostatic charging
Carefully observe the appropriate precautionary measures in order to avoid death or severe
injury.
For paint finish "resistant to sea air" (C4 according to EN ISO 12944-2) for motors
belonging to explosion group III, processes that generate significant levels of electrostatic
discharge are absolutely not permissible. Paint can be electrostatically charged as a result
of intensive dust turbulence or processes with high levels of electrostatic charging.
Electrostatic discharges can occur. Minimize the risk of electrostatic charging by applying
the following effective measures.
• Increase the conductivity of bulk goods and plant/system parts, e.g. by applying an
appropriate coating or paint finish.
• Increase the humidity or ionization.
• Reduce the amount of fine particles in bulk goods, e.g. resulting from abrasion.
• Restrict the degree of dispersion, e.g. by selecting plug conveying instead of dilute
phase conveying.
• Reduce the flow rate, the mass flow rate or the air velocity.
• Avoid large heaps of bulk goods.
• Transport using gravity is the preferred choice rather than pneumatic transport.
• When pneumatically transporting bulk goods, use conductive hoses in order to avoid
electrostatic discharge.
Additional measures are listed in IEC 60079-32-1.
Touch up any damaged paintwork
If the paint is damaged, it must be repaired in order to protect the unit against corrosion.
