Worktables should be made of wood and framed at the edge. [Pg.301]

The drying room or drier for the fireworks must not be multi-purpose, but planned exclusively for firework use. Drying in the sun is unavoidable, but if it is placed near workrooms this tends to conduct fire from one room to another in an accident, i.e., this violates the principle of separation. Careful consideration should be given to the position for drying in the sun. [Pg.301]

When we use a new machine, it must be tested first to see if it operates correctly and safely. For this purpose it is best to use an inert substance in place of the true composition if possible. Newly developed or designed machines are often out of order and this period is the most dangerous one. Repair of the machine should not be done until the composition has been completely removed from the machine. [Pg.301]

Reservoirs are extremely important structures in firework factories. The author experienced an accident where a worker ran out of a room on fire. He ran like mad with flames all over his clothes and the author pushed him into a near-by reservoir where he was saved. It is essential to have static water tanks near to rooms where fire can occur e.g. red phosphorus workshops. [Pg.301]
