1) Breathing Apparatus
There are two types of breathing
apparatus, the canister type gas mask and the oxygen or air-type
breathing unit. The canister type gas mask is limited in effectiveness;
it is appropriate for changing chlorine cylinders/containers
or normal maintenance work. It is not satisfactory for use
in repairing a leak. Therefore, either of the following types
of equipment should be furnished: the air-type breathing unit
(with 30 minutes air supply) or the oxygen breathing apparatus.
It is most important to equip the spare air or oxygen cylinder
for quick changing out at the site during long emergencies.
This unit must be placed in a prominently marked, easily accessible
location outside the chlorine room.
2) Chlorine Container/Cylinder
Emergency Kit
Every chlorination station should
have a least one chlorine container/cylinder emergency kit.
These kits are designed to seal off a leaking fusible plug,
a leaking outlet valve, or a moderate-size rupture in the
container shell. This unit also must be located in an easily
accessible location outside the chlorine room.
3) Leak Detector
There are two categories of leak
detectors: (1) continuous monitors of the working environmental
ambient air, and (2) hand-held personnel leak locators. There
should be at least one continuous detector for every chlorination
station to prevent hazardous situations for personnel and
the surrounding population, and to protect the chlorination
equipment. Second category of detectors is for searching or
checking for leaks in the fabricated components of the chlorine
supply system which is under chlorine equilibrium vapor pressure.
4) Ammonia Bottles
This unit is very useful to pinpoint
a leak.
5) Chlorine Gas Neutralization
System
This system is quite necessary
for every chlorination system. Refer to Engineering
Manual for Chlorine Gas Neutralization System written
