FIRE PROTECTION
5 Fire protection
5.1 Fire risks
The operator/owner is generally responsible for preventing fires/explosions.
The operator should establish the required measures in consultation with the appro-
priate bodies (e.g., occupational health and safety organizations, fire safety engineer,
fire brigade).
High heat generation, open fire or other ignition sources (e.g. cigarettes) in the vicini-
ty of the machine are prohibited.
An elevated risk of fire may arise in the following cases.
5.1.1 Combustible working materials and by-products
To combat fires caused by combustible materials or their dust (e.g. titanium), appro-
priate fire and explosion protection measures must be taken.
5.1.2 Minimal quantity lubrication system or dry machining
Using a minimal quantity lubrication system or dry machining poses a potential fire
risk.
Therefore, such a system may only be used after consulting the manufacturer. In
this case, it must be checked what other equipment (e.g., an exhaust unit) is re-
quired for the safe operation of the machine.
5.1.3 Combustible cooling lubricants
The use of some cooling lubricants in combination with certain manufacturing
parameters and the material to be machined poses an increased risk of deflagration
and fire.
As this puts the personnel at the machine at an elevated risk, suitable precautions
must be taken to prevent deflagration and fires.
Sufficient cooling must be ensured during the entire machining process in order to
prevent sparking. The cooling lubricant must be checked at regular intervals and its
correct fill level must be maintained.
The machine must be operated under supervision when using combustible cooling
lubricants. A machine is adequately supervised if a person can perceive the audible
and visual signals of the machine's fire extinguishing system and can react accord-
ingly.
The use of a fire extinguishing system is recommended when using water-based
cooling lubricant with an oil content greater than 15% or cutting oil based on mineral
oil.
