RISK OF DEATH, RISK OF EXPLOSION/RISK OF FIRE, RISK OF INJURY & RISK OF POISONING - AS82.10-Z-0001-01A

Do not come into contact with parts that are under high voltage. Persons with active electronic implants
(e.g. heart pacemakers) must never work on xenon headlamps. Switch off entire lighting system. Wear
insulated safety shoes, safety glasses and protective gloves. Remove highly inflammable materials from
the hazard area. Ensure sufficient ventilation in the working area.

Potential risks

Risk of death

Due to the high voltages involved, contact with live components at the xenon headlamps could be life
threatening!

Electric shocks can cause fibrillation of the heart or even cardiac arrest.

In addition, respiratory muscles may cramp up and result in respiratory failure.

Serious, possibly life-threatening, brain function disruptions are also possible.

It may take a few minutes for the consequences of an electrical shock to manifest themselves.

injury caused by UV
light, hot components at
xenon headlamps and
glass splinters produced
by bursting xenon bulbs.
Risk of poisoning caused
by inhalation of mercury
vapors and by toxic salts

into contact with skin

Injury hazard from

Risk of explosion/risk of fire

Highly flammable materials in the vicinity of damaged, energized xenon bulbs may result in explosion or cause
fires.

Risk of injury

UV light may escape when operating xenon bulbs not properly installed in the xenon headlamps. This UV light
may cause damage to the eyes (conjunctival infection) and to skin burns (sunburns) if skin is unprotected.

In both intact or faulty xenon headlamps, hot or glowing components may cause serious burn injuries if they
come into contact with unprotected skin or eyes.

Glass splinters produced by the destruction of xenon bulbs may cause cut injuries in unprotected skin and
unprotected eyes.

Risk of poisoning

When xenon bulbs are destroyed, serious health problems may be caused if the mercury vapors produced are
inhaled or if mercury compounds or toxic salts are ingested or absorbed through the skin. Possible
consequences include nausea, vomiting and gastrointestinal disruptions as well as degradation of the kidneys
and the central nervous system. Skin and eye damage may also result.

Safety precautions/instructions



Persons with electronic implants (e.g. pacemakers) must never work on xenon headlamps.



Wear safety shoes (with rubber soles).



Prior to working on xenon headlamps (e.g. replacing parts, hooking up test equipment, etc.), the complete
lighting system must be switched off and the xenon headlamps must be disconnected from the on-board
electrical system.



If the xenon headlamps are switched on, never touch components under high voltage.



If the xenon headlamps are switched on, maintain a clearance of at least 30 mm to components under high
voltage.



Avoid all contact with hot components.



Wait at least 3 min after switching off xenon bulbs before touching them.



Do not damage or destroy xenon bulbs.

Safety precautions/instructions



Never operate xenon bulbs unless they are properly installed in xenon headlamps with UV-absorbing
headlamp lenses.



Keep all highly flammable materials away from working area.



Wear suitable protective gloves and safety glasses.



Ensure that the workplace is sufficiently ventilated.
