Fuel Injectors & Pumps – Section 2.1 General Safety Precautions to Observe When Working On the Engine

To avoid injury or injury to bystanders from fumes, engine or vehicle fuel system service operations should be performed in a well ventilated area.‪

Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.‪

• Always start and operate an engine in a well ventilated area.
• If operating an engine in an enclosed area, vent the exhaust to the outside.
• Do not modify or tamper with the exhaust system or emission control system.

To avoid injury, never remove any engine component while the engine is running.‪

To avoid injury from an ejected injector unit pump, do not completely loosen the mounting bolts until you have tested the spring tension. If the spring tension is at maximum and you remove the mounting cap screws, the pump will be ejected from the engine crankcase.‪

To avoid injury from flying parts when working with components under spring tension, wear adequate eye protection (face shield or safety goggles).‪

To avoid injury from slipping and falling, immediately clean up any spilled liquids.‪

Some pressurized fluid may be trapped in the system. To avoid personal injury, loosen all connections slowly to avoid contact with fluid. When required, spray fluid into a proper container. The engine starting fluid used in DDEC Ether Start Systems contains extremely flammable and toxic substances.‪

To avoid injury from penetrating fluids, do not put your hands in front of fluid under pressure. Fluids under pressure can penetrate skin and clothing.‪

To avoid injury from flying debris, wear a face shield or goggles.‪

To avoid injury from fire caused by heated diesel-fuel vapors:‪

• Keep those people who are not directly involved in servicing away from the engine.
• Stop the engine immediately if a fuel leak is detected.
• Do not smoke or allow open flames when working on an operating engine.
• Wear adequate protective clothing (face shield, insulated gloves and apron, etc.).
• To prevent a buildup of potentially volatile vapors, keep the engine area well ventilated during operation.

To avoid injury from battery explosion or contact with battery acid, work in a well ventilated area, wear protective clothing, and avoid sparks or flames near the battery. If you come in contact with battery acid:‪

• Flush your skin with water.
• Apply baking soda or lime to help neutralize the acid.
• Flush your eyes with water.
• Get medical attention immediately.

To avoid injury when working near or on an operating engine, remove loose items of clothing and jewelry. Tie back or contain long hair that could be caught in any moving part causing injury.‪

To avoid injury when working on or near an operating engine, wear protective clothing, eye protection, and hearing protection.‪

To avoid injury from flying debris when using compressed air, wear adequate eye protection (face shield or safety goggles) and do not exceed 276 kPa (40 psi) air pressure.‪
