The following is a summary of the measures and precautions taken by the School of Science to control the spread of COVID-19.

1 COVID-19 Prevention Poster

The School of Science has created a poster to help prevent the spread of COVID-19. We would appreciate your cooperation in using this poster, such as hanging it in front of entrances of School of Science buildings. Please feel free to contact us if you are interested in an A1/A2 size color poster.

2 Alcohol-Based Hand Sanitizer Locations

The alcohol-based hand sanitizers provided by the School of Science contain 58% alcohol as solutions containing more than 60% alcohol are considered hazardous materials under the Fire Service Act. If you are running out of hand sanitizer, please bring the container to the Disaster Prevention Center (1F, Area E, School of Science Bldg. 1) to refill it.

2.1 Entrances of buildings, offices, etc.

消毒用アルコール
  • Hand sanitizers and stands were distributed on February 25, 2020, and placed around entrances of buildings and offices.
  • Hand sanitizers were distributed to School of Science Bldgs. 2 and 3, and Koishikawa Botanical Garden in polyethylene tanks (to be refilled by the Environmental Safety Management Office).

2.2 Classrooms

Automatic hand sanitizer dispensers were installed outside of classrooms on June 22, 2020. 講義室入口

2.3 In front of washrooms, etc.

  • Hand sanitizers were distributed on June 25, 2020, and placed in front of washrooms and elevators in buildings at Hongo and Asano, and in nearby remote areas.

5 Precautions Regarding Infectious Disease Prevention and Control

5.1 On the use of alcohol-based sanitizers

Sanitizers that contain more than 60% alcohol are classified as hazardous materials under the Fire Service Act. When using these sanitizers, please pay careful attention to the following:

  • Do not use near open flame or other heat sources.
  • Do not spray directly onto electrical equipment such as switches.
  • Be cautious of leaks, spills, or splashes when refilling containers. Make sure the containers are properly labeled with “Caution: Flammable”.
  • Keep away from direct sunlight and high temperatures.
  • Please ensure that there is adequate ventilation when you disinfect a room or refill sanitizers and avoid spraying large amounts of alcohol-based sanitizer in a closed room to prevent the accumulation of flammable alcohol vapors.

5.2 On the use of liquid sodium hypochlorite

Please pay close attention to the following when using liquid sodium hypochlorite:

  • Do not apply liquid sodium hypochlorite to skin as it is a strong irritant.
  • Wear resin gloves, such as vinyl, when handling liquid sodium hypochlorite.
  • If you get liquid sodium hypochlorite onto your skin or clothes, wash it off immediately with water.
  • Ensure that the room is well-ventilated when using liquid sodium hypochlorite.
  • As liquid sodium hypochlorite corrodes metals, it should be wiped off with water after use.
  • Do not mix liquid sodium hypochlorite with any strong acidic detergent as it will create a toxic gas.
  • Keep away from direct sunlight and high temperatures.

5.3 On the installation of plastic sheets to prevent the spread of the disease

Please pay careful attention to the following if you are planning on installing plastic sheets in an office/laboratory:

  • Do not install near open flame or other sources of heat, such as heaters, incandescent bulbs, etc.
  • When hanging anything from the ceiling, ensure that there is adequate space in order to avoid obstructing firefighting equipment, such as sprinkler heads or fire alarms.
  • Try to use a flame resistant or flame retardant sheet.
  • It is important to use a sheet made of fireproof retardant material in the School of Science Bldg. 1 as it is a multistory building.
  • Precautions to take when installing a plastic sheet (Tokyo Fire Department — in Japanese only)
