14. Procedural hazards
Place notices in prominent positions, to indicate that personnel are working on the
equipment. It is recommended that other personnel are in close proximity.
NEVERWORKALONE.
Do not use fingers as guides when installing parts or to check alignment of bolts.
Cap all open lines and fittings during maintenance to prevent entry of contaminants into
systems. Ensure that all loose items such as nuts, washers and spare wiring are removed
from the installation and air intake before starting.
15. Tooling hazards
Improperly maintained tools and support equipment can be dangerous to personnel and can
damage turbocharger parts. Maintain tools and equipment in good condition to avoid
unanticipated failures. Use tooling only for the purpose for which it was designed, and avoid
abuse. Inspect for wear or damage, and initiate appropriate action for immediate approved
repair or replacement.
16. Use of lifting equipment (slings, cranes etc.).
Before using any lifting equipment, ensure:
i) The equipment is the correct type for the task.
ii) The equipment has valid test certificate and the safe working load is marked on the
equipment.
iii) Shackles, slings are in good condition.
17. Safe exposure to noise
Very loud noise causes serious and irreparable hearing damage and studies have shown that
continuous exposure to noise levels over 85dB(A) causes hearing damage. NAPIER
recommends the use of hearing protection at this level and above. Indicative safe times in
high noise surroundings without ear protection are shown below, however international
standards and regulations should be referred for definitive figures.
It is the responsibility of engine operators to monitor noise levels and advise personnel
accordingly about the use of hearing protection.
18. Pre-start
Before starting the turbocharger ensure that no maintenance operation is being conducted,
and personnel are clear of the air inlet and exhaust, and that any loose articles, cleaning
materials, tools etc. have been removed.
Before operating the turbocharger understand the operating procedures and system
functions thoroughly. Know and understand all indicators, normal indications and operating
limits.
Be aware of possible malfunctions by studying the instructions supplied, and be prepared to
take appropriate action in the event of any emergency.
