(1) Confirm that the safety of the workers is ensured.
(a) Check the progress of the preparation before starting the procedures
A. Do the workers wear a personal dosimeter?
Determine who wears a personal dosimeter depending on how many they are
available. Let each staff who wears the dosimeter fill the dosimeter number, his
name, reading of the dosimeter when he worn and reading at the end of the
day’s work in the form, “Record 6: Record of personal dosimeters”.
B. Are the worker ready for starting the procedures?
Wear, in principle, long boots and long pants because the workers will handle
water. Half-leaved working jacket may be allowed. The workers require
wearing rubber gloves when handling precipitate generated during the
treatment using zeolite.
C. Are the workers prepared for heat stroke?
Measures against heat strokes are essential for the work during summer
season. Prepare hats, sunscreen and water with them. A water fountain may be
effective.
D. Have consumables commonly used by the workers been prepared?
Consumables to be required during the work should be prepared in advance,
which include first-aid kit for the treatment of slight injuries, waste cloths,
paper towels, rubber gloves and masks.
E. Prepare trash bags for segregation of waste
Wastes generated directly from the decontamination procedures and those
generated in other work than decontamination should be recovered in separate
bags to prevent their mixing.
(b) Confirm responses in case of injury or accident
The procedures are conducted at the slippery place around the swimming pool.
Caution will be required not to tumble or fall into the pool. Particularly in
summer, it tends to be hot at the pool side due to a combination of direct and
