Particular attention shall be drawn on some precautions that
must be followed absolutely in a standard working area and
whose n on fulfillment will make any other measure useless or
not sufficient to ensure safety to the personnel in−charge of
maintenance.
Be infor med and inform personnel as well of the laws in force
regulating safety, providing information documentation
available for consultation.
- Keep working areas as clean as possible, ensuring adequate
aeration.
- Ensure that working areas are provided with emergency
boxes, that must be clearly visible and always provided
with adequate sanitary equipment.
- Provide for adequate fire extinguishing means, properly
indicated and always having free access. Their efficiency
must be checked on regular basis and the personnel must
be trained on intervention methods and pri orities.
- Or ganize and displace specific exit points to evacuate the
areas in case of emergency, providing for adequate
indications of the emergency exit lines.
- Smoking in wor king areas subject to fire danger must be
strictly prohibited.
- Provide War nings throughout adequate boards signaling
danger, prohibitions and indications to ensure easy
comprehension of the instr u ctions even in case of
emergency.
- Do not execute any intervention if not provided with
necessary instructions.
- Do not use any tool or equipment for any different
operation from the ones they’ve been designed and
provided for: serious injury may occur.
- In case of test or calibration oper ations requiring engine
running, ensure that the area is sufficiently aerated or utilize
specific vacuum equipment to eliminate exhaust gas.
Danger: poisoning and death.
Standard safety prescriptions
Prevention of injury
- Do not wear unsuitabl e c loths for wor k, with flutter i ng
ends, nor jewels such as ri ngs and chains when working
close to engines and equipment in motion.
- Wear safety glov es and goggles when performing the
following operations:
− filling inhibitors or anti−frost
− lubrication oil topping or replacement
− utilization of compressed air or liquids under pressure
(pressure allowed: ≤ 2bar)
- Wear safety helmet when working close to hanging loads
or equipment working at head height level.
- Always wear safety shoes when and cloths adheri ng to the
body, better if provided with elastics at the ends.
- Use protection cream for hands.
- Change wet cloths as soon as possible
- In presence of current tension exceeding 48−60 V verify
efficiency of earth and mass electrical connections. Ensure
that hands and feet are dry and execute working
operations utilizing isolating foot−boards. Do not carry out
wor king operations if not tr ained for.
- Do not smoke nor light up flames close to batteries and
to any fuel material.
- Put the dirty rags with oil, diesel fuel or solvents in anti−fire
specially provided containers.
During maintenance
- Never open filler cap of cooling circuit when the engine is
hot. Operating pressure would provoke high temperature
with serious danger and risk of burn. Wait unit the
temperature decreases under 50ºC.
- Never top up an overheated engine with cooler and utilize
only appropriate liquids.
- Always operate when the engine is turned off: whether
particular circumstances require maintenance
intervention on running engine, be aware of all risks
involved with such operation.
- Be equipped with adequate and safe containers for
drainage operation of engine liquids and exhaust oil.
- Keep the engine clean from oil tangles, diesel fuel and or
chemical solvents.
- Use of solvents or detergents dur ing maintenance may
originate toxic vapors. Always keep working areas aerated.
Whenever necessary wear safety mask.
- Do not leave rags impregnated with flammable substances
close to the engine.
- Upon engine start after maintenance, undertake proper
preventing actions to stop air suc tion in case of runaway
speed rate.
- Do not utilize fast screw−tightening tools.
- Never disconnect batter i es when the engine is running.
- Disconnect batteries before any intervention on the
electr ical system.
- Disconnect batteries from system aboard to load them
with the battery loader.
- After every intervention, verify that battery clamp polarity
is correct and that the clamps are tight and safe from
accidental short circuit and oxidation.
- Do not disconnect and connect electrical connections in
presence of electr ical feed.
- Before proceeding with pipelines disassembly (pneumatic,
hydraulic, fuel pipes) verify presence of liquid or air under
pressure. Take all necessary precautions bleeding and
draining residual pressure or closing dump valves. Always
wear adequate safety mask or goggles. Non fulfillment of
these prescriptions may cause seri ous injury and
poisoning.
