BMW X5: Safety At Work

1.1 Working with aluminum dust:

• Wear a fine dust mask.
• E52 only: Use an explosion-proof extractor system.
• Note national regulations.

1.2 Removing sealing materials

• Hydrochloric acid is created when PVC sealing material is heated to temperatures in excess of 180º C.
• Remove PVC sealing material with a rotating wire brush only or heat material with a hot air blower to max. 180ºC and remove with a spatula.
• Ensure that all enclosed areas are well ventilated or are provided with direct extractor facilities.

1.3 Arc welding and brazing:

IMPORTANT: The extremely bright arc during welding may cause serious injury to the eyes if appropriate protective measures are not taken.

• Use a special welding screen* for the relevant welding process (MAG or MIG).
• Partition off the work bays with beam protection screens*.
• Use a welding-emissions extractor facility*.
• The welder must wear protective clothing* and gloves* which are suitable for welding (i.e. flameproof).
• A fire extinguisher must be located within reach of the welding area.
• Do not carry out any welding work in the proximity of a fuel tank e.g. when it is installed.
• Note national regulations.

*Sourcing reference: refer to WORKSHOP EQUIPMENT PLANNING CD.

1.4 Working with adhesive products (adhesives, cleaning agents, primers etc.):

IMPORTANT: Handling adhesives can trigger off allergic skin and breathing reaction

• Do not eat, drink or smoke during this operation.
• Avoid direct contact with eyes and skin.
• Wear protective goggles, protective gloves and if necessary an apron.
• Ensure that all enclosed areas are well ventilated or are provided with direct adhesive fume extractor facilities.
• Work clothing which has been contaminated with adhesive or solvent must be changed immediately.
• After finishing work, wash your hands and apply protective skin cream.
• Always keep an eye bath on hand, change the water regularly (once a month).
• Store adhesive products in a secure cabinet only.
• Keep adhesive products away from naked flames and other ignition sources.
• Protect adhesive products against strong heat sources and direct sunlight.
• Note national regulations.

First Aid:

In the event of eye contact, flush immediately with running water for approx. 10-15 minutes and, if necessary, visit eye specialist.

In the event of skin contact and where applicable an allergic skin reaction, clean the affected areas immediately with soap and water and then apply silicone-free skin cream. If necessary, consult a doctor.

If an adhesive product is swallowed, rinse mouth/parts of mouth thoroughly with running water. Drink 1-2 glasses of water. Do not induce vomiting. Consult a doctor.

If adhesive fumes are inhaled, ensure a constant supply of fresh air, keep calm, keep respiratory tracts unobstructed and consult a doctor.

SPOT-WELD BONDING STEEL PARTS

IMPORTANT: Comply with the following topics from "Body, General": Safety regulations.

Welding steel parts.

• The spot-weld bonding process is used starting from the E65 to increase vehicle rigidity. In partial bodywork areas, a 1-component adhesive is applied to the spot flanges and this is followed by resistance pressure spot welding. The adhesive is hardened only after the paint drying process (at approx. 180ºC).
• In the case of repairs, adhesive is not applied to the spot flanges. The number of welding spots is doubled as a substitute for the omitted adhesive.
• The following processes are used as a substitute for spot-weld bonding:
  • MAG welding (M etal A ctive G as welding)
  • Resistance pressure spot welding (referred to in the following and in the repair instructions as spot welding).
• Adhesive is not applied between the spot flanges on new parts in the case of 2 - or multi-sheet joints.

  Areas which cannot be reached by the spot-welding tongs can be joined by MAG spot welding. The number of welding spots is doubled as a substitute for the omitted adhesive.

  Exceptions (e.g. E65) are described in the relevant repair instructions. Apply welding spots to existing welding spots on new part. This is necessary because the adhesive between the spot flanges of the new part acts as an insulator.

CAUTION: Extract smoke and fumes during welding work.
