4.7.1 Fire hazards Such hazards can be generated by, e.g.:  ignition of flammable paint and varnish deposits inside the spray booth, in exhaust ducts and filtration units;  when the spray booth is in operation a misuse or mechanical or electrical defects can cause ignition of these deposits. This is especially valid in electrostatic spray booths; in maintenance operations requiring use of cutting or welding tools, energy released can also initiate a combustion; The fast propagation of fire induces a risk for the neighbouring areas.  failure of liquid coating material or solvent or combustible liquid pipes or fittings with exit of flammable liquids inside the spray booth;  ignition of cleaning rags containing solvents;  auto-ignition created from chemical reactions between different types of liquid coating materials;  electrostatic equipment, badly driven items or control system malfunction causing electric arcs between items to be painted and machinery parts at high voltage. Hence electric arcs can provoke the ignition of the paint aerosol. This can especially occur in plant using robots or automated machines;  heating devices capable of igniting solvents. NOTE Examples of ignition sources are:  hot surfaces e.g. of heating systems and electrical equipment;  sparks created by mechanically induced energy e.g. fans, conveyors, etc.;  electrostatic discharges;  electrical sparks;  welding and other sources of thermal energy used during maintenance and cleaning. 4.7.2 Explosion hazards Such hazards can occur when the concentration of the flammable substances in air exceeds the lower explosion limit (LEL) and if an effective ignition source is present. NOTE 1 Examples of flammable substances which increase concentration above the normal:  solvent vapours from the flash off process; SIST EN 12215:2005+A1:2009
