Baosteel, a large steel manufacturer
in China, is entrusting the safety of
personnel at its Shanghai plant to
trapped key interlocking systems
from Castell.

Many steel plants in China still
rely on warning signs to remind
employees of recommended
operating procedures. However, this
method is prone to abuse, with
potentially disastrous consequences.

Castell’s products are being used
to ensure that Baosteel’s electrostatic
plating process is carried out safely.

The three interlocking systems
eliminate the risk of personnel who
ignore safety procedures putting
themselves in danger, by forcing
operatives to strictly follow a
predetermined series of steps based
on the transmission of keys.
