removed. All penetration screens should be checked to ensure
that openings are protected. The ceiling of the storage facility
should be checked for cracks (look for daylight). Finally, any
materials that are placed in the facility following the cleaning
must be clean and sanitary.
Chlorination Safety
All safety precautions as indicated by the Chlorine Institute
should be followed when performing chlorination procedures.
Working on or in a storage facility can be hazardous. There may
be regulatory requirements that apply to ensure that these pro-
cedures are conducted in a safe manner. Appropriate regulatory
agencies and requirements should be consulted before beginning
any chlorination procedure. Some precautions include:
•
Personal protective equipment, such as goggles, gloves,
and breathing apparatus.
Special fans or other ventilation equipment for use
within storage facilities.
Adequate lighting.
Electrical equipment that is specifically designed for
safe use in a wet environment.
Protective clothing.
Safety cages or cables to prevent accidents on ladders or
entry steps.
Confined space entry regulatory requirements.
Removal of Highly Chlorinated Water
Discharge regulations (applicable locally) may dictate the
methods of disposal for highly chlorinated water. This is particu-
larly applicable to the full storage facility chlorination method.
When using this method, the entire volume of the storage facility
contains water with a chlorine residual greater than 10 mg/L.
Environmental protection regulations may require special provi-
sions or permits prior to disposal of this water. Dechlorination
may be required (methods are described in Chapter 7). The proper
authorities should be contacted prior to disposal to determine all
