The hydrofluoric acid may remain on the machine parts for
several years after a fire.
If swelling, redness or a stinging feeling appears and one
suspects that the cause may be contact with heated fluoro-
carbon rubber, contact a medical doctor immediately. Several
hours may pass, however, before any symptoms appear and
there is no immediate warning.
The acid cannot be rinsed or washed off from the skin. Treat
instead with Hydrofluoric Acid Burn Jelly or similar before
contacting a medical doctor.

Crystalline silica is a basis component of sand and granite.
Therefore, many activities at construction and mining sites, such
as trenching, sawing and boring, produce crystalline silica dust.
This dust can cause silicosis.
The employer or working site management should provide the
operator with information about the presence of crystalline silica
in the work site along with specific work instructions and
precautions and also necessary personnel protection equipment.
Also check the local / national regulations regarding silica /
silicosis.
