Make sure that everyone working with STONE-TECH^® understands the possibility of blowout
    shoots, and has read the technical instructions thoroughly.
  STONE-TECH^® is a highly alkaline material, its pH reaches 13 after contact with water and can
    cause severe irritation to mucous membranes, especially eyes. Skin and eye contact with
    STONE-TECH^® must be rinsed off with large amounts of cold water immediately without rubbing.
    Consult a doctor quickly.
  Wear safety goggles and rubber gloves during STONE-TECH^® handling, mixing and filling. Dust-
    proof mask is recommended in poorly ventilated areas such as tunnels or mines.
  Do not get your face close to or stand near the filled holes for at least 3 hours after filling
    completion.
  Warm or bubbling mortar is forbidden to be filled into holes. Once filled holes start to smoke or
    steam, that is the sign they may be about to blow out. Clear the area of people immediately.
  Keep people away from jobsite after filling holes. In case that people have to remain in the area,
    cover filled holes with a tarpaulin.
  Once a blowout shot has occurred, there may be 3~4 other shots out the same hole and in other
    holes as well.
  Take care of fall of the cracked block from the cracking object.
