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.
Handling electrical/electronic equipment, airbags and restraint systems.
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.
