➤ Do not operate in areas in which specific requirements regarding explosion protection are in force.
For instance, the requirements of the ATEX directive 94/9/EC "Equipment and Protective Sys‐
tems for use in Explosive Atmospheres".
➤ Ensure adequate ventilation.
➤ Ensure that required ambient conditions are maintained with regard to:
■ Ambient temperature
■ Clean inlet air with no damaging contaminants
■ Inlet air free of explosive or chemically unstable gases or vapours
■ Inlet air free of exhaust gasses from internal combustion engines
■ Inlet air free of acid/alkaline forming substances, particularly ammonia, chlorine or hydrogen
sulphide.
➤ Do not position the machine in warm cooling outlet air from other machines.
➤ Ensure accessibility so that all work on the machine can be carried out without danger or hin‐
drance.
➤ Chock the wheels to prevent unwanted movement.
➤ Do not place additional loads on the machine (e.g. excavator bucket as anti-theft measure).
Operation
➤ Keep the access doors closed for safety, quiet running and to ensure correct cooling air flow.
➤ Carry out regular inspections:
■ for visible damage and leakage,
■ of safety devices,
■ of components needing to be monitored.
➤ Never operate machines without an air filter when drawing in air from the surroundings.
Maintenance
➤ Make sure the machine is shut down, cooled down and pressure-free before commencing any
maintenance work.
➤ Wear close-fitting, flame-resistant clothing. Wear protective clothing as necessary.
➤ Do not leave any loose components, tools or cleaning rags on or in the machine.
➤ Components removed from the machine may still be a source of danger.
Do not open or destroy components removed from the machine as some, inlet valves, for in‐
stance, are powerfully spring-loaded.
De-commissioning, storage and disposal
➤ Drain out fluids and dispose of according to environmental regulations.
These include, for example, fuel, engine oil and compressor cooling oil and engine coolant.
➤ Dispose of the machine in accordance with local environmental regulations.
3.5.3 Organisational Measures
➤ Designate personnel and their responsibilities.
➤ Give clear instructions on reporting faults and damage to the machine.
➤ Give instructions on fire reporting and fire-fighting measures.
