Risk of injury & Rick of poisoning - AS00.00-Z-0013-01A

WARNING: This page does not describe the selected car, but rather 42 other vehicles, including the 1999 Mercedes-Benz S600, 1999 Mercedes-Benz S500, 1999 Mercedes-Benz S420, 1999 Mercedes-Benz S320, and 1999 Mercedes-Benz CL600. However, it is still accessible from the selected car via links, so may be relevant.

Depressurize the hydraulic system completely before starting any work on the system. Wear protective clothing and eye protection.

Possible hazards

Risk of injury

When disengaging hydraulic lines without first depressurizing the system, dangerous skin or eye injuries may occur due to the very high pressures (in excess of 200 bar). If hydraulic fluid, particularly central hydraulic fluid (especially harmful), comes into contact with unprotected skin, this may cause damage to the skin.

Risk of poisoning

If hydraulic fluid is swallowed, this may lead to poisoning symptoms such as headache, giddiness, abdominal pain, vomiting, diarrhea, cramps and unconsciousness.

Protective measures/guidelines

When commencing work on hydraulic systems, these must be depressurized; the system must be drained if necessary.
Do not pour hydraulic fluid into beverage containers.
Ensure sufficient ventilation, especially in the case of central hydraulic fluid.
Ensure that only authorized persons have access to hydraulic fluid.
Immediately seal disconnected leads and hoses, and the connections to the assemblies, with blind plugs.
Wear protective gloves, protective clothing and eye protection.

If protective gloves cannot be worn, the following points must be noted:

Only expose skin to hydraulic fluid for as brief a period as possible; in the event of contact with skin, clean skin with soap and water.
In the event of contact with clothing, replace clothing as rapidly as possible.

First-aid measures

Have the person affected drink plenty of water with activated charcoal additive.
After swallowing large volumes, seek the attention of a physician.
If hydraulic fluid gets into the eyes, immediately rinse the eyes with plenty of clean water/eye rinsing bottle.
In the event of injuries to the skin or eyes due to a jet of hydraulic fluid, immediately seek the attention of a physician.
