Management of Chemical Substances

Importance of chemical substance management

There are many chemical substances that have hazardous properties such as explosion, ignition, health disorder, and environmental pollution.Especially at universities, where advanced research is being conducted, we sometimes handle chemical substances whose dangers and hazards are unknown.
In Japan, chemical substances are regulated by various laws. For example, substances that are toxic to the human body are regulated under the Poisonous and Deleterious Substances Control Act, and substances that pose a risk of causing explosions or ignition are regulated under the Fire Service Act, and are defined as "Hazardous Material. It is important to remember that chemical substances have many other aspects, such as the need to handle and monitor exposure to them to prevent health disorder, or the fact that they are environmental pollutants.

4. Usage

Use of chemical substances (Article 13 of the Rules)

Chemical substances have various risks (fire / explosion, health disorders, environmental pollution). However, universities handle a large number of chemicals, and it is impossible to learn about the hazards of all the chemicals in lectures. Therefore, students should acquire the skills to investigate the hazards before handling them.
In addition, the Chemical Substance Manager must conduct a risk assessment of the hazards of the chemical substances to be handled and inform the chemical substance handlers of the results. The hazards and dangers can be obtained from the Safety Data Sheet (SDS). In particular, if the results of the risk assessment indicate that the substance is highly harmfulness, discontinue use or consider alternative substances. If it is difficult to do so, shorten the handling time or take measures such as containment of the chemical substance.
Basically, for highly harmfulness substances, take measures to prevent exposure and dispersal. If there is a Local exhaust ventilation (draft chamber), be sure to use it. (In this case, check before use whether there is air intake by the draft chamber, whether there is any abnormal noise, and whether the water from the scrubber system is flowing.
For the above reasons, smoking, eating, and drinking are prohibited in the laboratories where chemical substances are used, and only relevant personnel are allowed to enter. Also, please post a notice (designated by Kumamoto University) regarding these matters.

有機溶剤の使用
Use of specified chemical substances (Article 10 of the Guidelines)

Among chemical substances, there is a type of chemical substance called "specified chemical substances" as defined by the Industrial Safety and Health Act. This indicates health hazards, so care must be taken when using them.
Work environment measurements are carried out in places where specified chemical substances are used. This is a scientific measurement to find out how much toxic substances are scattered by your handling, so please cooperate.
Among the specified chemical substances, there are chemical substances called "specially controlled substances". When handling these chemical substances, a record of use (work outline and period) and posters must be posted. Usage records must be submitted once a month and kept for 30 years. Those posters describe the effects on the human body, precautions for handling, and protective equipment to be used. Those posters can be downloaded from YAKUMO.

Use of High Pressure Gases (Article 8 of the Guidelines)

High pressure gas should be handled with due consideration for its toxicity, combustion-supporting properties, and explosivity, and other hazards.
If a high pressure gas container has been rented, return it within one year.
In addition, used-up high pressure gas containers (excluding self-owned containers) should be returned to the vendor immediately.

5. Disposal

Disposal of Chemical Substances (Article 14 of the Rules)

Dispose of chemical substances in accordance with environmental laws and regulations and the instructions of the Environmental Safety Center.

化学物質の廃棄

Experiment waste liquids, unnecessary chemicals, toxic sludge, mercury-containing apparatuses are undertaken by the Environmental Safety Center. Please visit the following website.

Wastes with chemical substances attached (or likely to be attached) should be disposed of as industrial wastes. Never dispose of them together with general waste (so-called "household waste") at garbage collection points. In the Kurokami and Oe districts, the Environmental Safety Center collects experimental waste twice a month. In the Honjo districts, empty containers are collected as "experimental waste" and the rest as infectious waste, etc.
Chemical substances must be disposed of if they are not to be passed on to the next group, for example, when a chemical handling group is discontinued.
