Safety rules:
T8.275 WE, T8.300 WE, T8.330 WE, T8.360 WE, T8.390 WE, T8.420 WE
Standard safety precautions
Be informed and notify personnel of the laws in force regulating safety, and provide documentation available for consultation.
• Keep working areas as clean as possible.
• Ensure that working areas are provided with emergency boxes. They must be clearly visible and always contain adequate sanitary equipment.
• Fire extinguishers must be properly identified and always be clear of obstructions. Their efficiency must be checked on a regular basis and personnel must be trained on proper interventions and priorities.
• Keep all emergency exits free of obstructions and clearly marked.
• Smoking in working areas subject to fire danger must be strictly prohibited.

Prevention of injury:

• Wear suitable work attire and safety glasses with no jewelry such as rings and chains when working close to engines and equipment in motion.
• Wear safety gloves and goggles when performing the following operations:
• Topping off or changing lubrication oils.
• Using compressed air or liquids at a pressure greater than 2 bar (29 psi).
• Wear a safety helmet when working close to hanging loads or equipment working at head level.
• Always wear safety shoes and fitting clothes.
• Use protection cream for hands.
• Change wet clothes as soon as possible.
• In the presence of voltages exceeding 48 – 60 V, verify the efficiency of the ground and mass electrical connections. Ensure that hands and feet are dry and use isolating foot boards. Workers should be properly trained to work with electricity.
• Do not smoke or start an open flame close to batteries and any fuel material.
• Place soiled rags with oil, diesel fuel or solvents in specially provided anti-fire containers.
• Do not use any tool or equipment for any use other than what it was originally intended for. Serious injury may occur.
• If running an engine indoors, make sure there is a sufficient exhaust fan in use to eliminate exhaust fumes.

During maintenance:

• Never open the filler cap of the cooling system when the engine is hot. High temperature liquid at operating pressure could result in serious danger and risk of burn. Wait until the temperature decreases under 50 °C (122 °F).
• Never add coolant to an overheated engine and use only appropriate liquids.
• Always work when the engine is turned off. Certain circumstances require maintenance on a running engine. Be aware of all the risks involved with such an operation.
• Always use adequate and safe containers for engine fluids and used oil.
• Keep engine clean of any spilled fluids such as oil, diesel fuel, and or chemical solvents.
• Use of solvents or detergents during maintenance may emit toxic vapors. Always keep working areas aerated. Wear a safety mask if necessary.
• Do not leave soiled rags that may contain any flammable substances close to the engine.
• Always use caution when starting an engine after any work has been performed. Be prepared to cut off intake air in case of engine runaway.
