9.10 Shielding

Safety shielding should be used for any operation having the potential for explosion and must be placed so that all personnel in the area are protected from hazard, such as whenever:

  1. A reaction is attempted for the first time (small quantities of reactants should be used to minimize hazards).
  2. A familiar reaction is carried out on a larger than usual scale (5-10 times more material).
  3. An operation is carried out under non-ambient conditions.
