5. Center for Management of Information Technologies (CMIT)
The CMIT is a University-wide shared facility. Precautions for using this Center are
posted in the facility and must be observed. Regarding the use of equipment at the CMIT,
you need to be careful when working for a long time in front of a display screen. The
following health problems can be caused by long-term use of display terminals (VDTs):
Eyes – Eye discomfort can include visual haze, pain/redness, deterioration of visualfunction (abnormal color vision and decreased visual acuity), pain in other parts of the
body caused by these symptoms, stiffness, dizziness, and fatigue.
Localized body pain – Symptoms can include stiff shoulders, limb pain, cervicobrachialdisorder, and headaches.
Mental – Mental effects can include poor motivation, poor concentration and memory,
and, in extreme cases, seizures and emotional disturbance.
Among reported cases, many cases manifested poor eyesight and abnormal color vision.
Because these symptoms are likely to be caused by a VDT, maintenance of an appropriate
working environment (natural posture, correct display settings, and appropriate
surroundings) is essential. While keeping in mind the balance of brightness and othersettings, users should regularly perform visual acuity checks. If any abnormality is foundafter undergoing examinations, such as force, adjustment, intraocular pressure, andfundus observation, it is necessary to take immediate action.
However, even with the current VDT equipment, no major problems will occur as longas the work environment and work time are appropriately managed and a use method
suitable for each person is observed.

Hazardous materials indoor storage

6.1 Overview of hazardous materials“Hazardous materials” in this chapter refers to hazardous materials defined by the Fire
Service Act, which is a Japanese law. Hazardous materials are substances that are
combustible or easily ignited as defined by the Fire Service Act. These hazardous
materials are classified into Categories 1 to 6 according to their properties, and thehandling of each class is different.
Because these materials have properties such as a high risk of spreading a fire and a highdegree of difficulty in extinguishing such fires, they should be handled with great care.
6.2 Handling of hazardous materials
When handling hazardous materials, even when using a small amount, be aware of thedangers and physical properties of the substance before using it. Review the material’s
Safety Data Sheet (SDS) to learn its hazards and appropriate handling methods.
A hazardous materials engineer’s license is required to handle hazardous materials in astorage facility where the multiple of the designated quantity exceeds 1. Therefore, aperson with a Class A or Class B hazardous materials engineer’s license must be present
when removing hazardous materials from the storage facility of the Faculty ofEngineering.
6.3 Storage of hazardous materials
For hazardous materials, the “designated quantity” is stipulated by law in considerationof the danger. If the value obtained by dividing the amount of hazardous materials inpossession by the specified quantity exceeds 1, the Fire Service Act strictly regulates thestorage and handling of substances. Therefore, when storing a large amount of hazardous
materials, it is necessary to obtain permission from the local fire department to store
hazardous materials in a storage facility that meets the standards based on the Fire Service
Act, and to notify the local fire department of the storage contents. If the same categoryof hazardous materials but different substances are stored, divide the storage amount ofthese hazardous materials by the respective designated quantity and sum the values
obtained. If the sum of the quotients exceeds 1, it is subject to the Fire Service Act.
Even if it exceeds 1/5 of the multiple of the designated quantity, it is necessary to notify
the fire department under the jurisdiction of the municipality as a “small-quantity
hazardous materials”. Therefore, if you need to store hazardous materials in yourlaboratory, store them in the designated hazardous materials storage location, and removeonly the amount you need for immediate use.
6.4 How to use the indoor hazardous materials storage facility
Municipalities must be notified in advance of the identity and quantity of hazardous
materials to be stored in an indoor hazardous materials storage area. Thus, the types ofhazardous materials and the maximum amount that can be stored in the hazardous
materials indoor storage area of the Faculty of Engineering have already been decided.
The hazardous materials security superintendent, the hazardous materials that can be
stored, and the amount are specified in the hazardous materials indoor storage is written
on the storage facility. If you want to store unapproved chemicals, the university mustobtain storage permission from the municipality in advance, so consult with thehazardous materials security superintendent before acquiring such materials.
When storing hazardous materials in the hazardous materials indoor storage area, toclearly identify the person who manages the chemicals, the name of the laboratory or
faculty member should be written on the label or can, and a sticker issued by YAKUMO
should be affixed to the can when it is placed in storage. After storing it, be sure to change
the storage location to the hazardous materials indoor storage area in YAKUMO.
The hazardous materials indoor storage area cannot store anything other than the specified
categories of hazardous materials. However, non-hazardous materials that do not reactwith hazardous materials can be stored if certain conditions are met. At present,
chloroform and dichloromethane can be stored as category 4 materials in the hazardous
materials indoor storage area of the Faculty of Engineering. When storing these chemicals,
place them in a designated storage area that is at least 1 m away from dangerous materials.
