Headlamp: Service Precautions
AS82.10-Z-0001-01A Risk Of Death Caused By High Voltage At Xenon Headlamps
- with CODE (612) Xenon headlamp unit
- with CODE (614) Bi-xenon headlamp unit
- with CODE (615) Bi-xenon headlamp unit with integrated curve illumination
Risk of death caused by high voltage at xenon headlamps. Risk of explosion/risk of fire caused by highly flammable materials in the vicinity of damaged xenon bulbs. Risk of 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 and mercury compounds being ingested or coming into contact with skin
Danger: 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.
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 (conjunctivitis) 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 to 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 damage to the kidneys and the central nervous system. Skin and eye damage may also result.
Safety precautions/instructions
- Persons with active electronic implants (e.g. heart 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 minutes 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 the work place is adequately ventilated.
First aid measures
Electrical shock
^ Switch off current, bring injured person to safety.
^ Immediately notify an emergency physician.
^ Perform mouth to mouth respiration, if necessary.
^ Perform cardiopulmonary resuscitation, if necessary.
Burn injuries
^ Cool affected skin area with cold water.
^ Cover burn wounds with sterile dressing.
^ Consult a physician.
Cut injuries/skin injuries
^ Stop the bleeding.
^ Dress cut/skin injury.
^ Consult a physician.
Foreign object in eye
^ Cover eye with sterile dressing.
^ Cover both eyes to calm them.
^ Consult an eye doctor immediately.
Eye contact with mercury vapors/toxic salts
^ Flush eyes with lukewarm water.
^ Cover eye with sterile dressing.
^ Consult an eye doctor immediately.
Eye contact with UV light
^ Consult an eye doctor immediately.
Poisoning caused by inhaling mercury vapors
^ Take victim to fresh air.
^ Consult a physician immediately.
Poisoning caused by ingesting toxic salts or mercury compounds
^ Consult a physician immediately.
Always consult a medical service or physician after administering first aid.
