1.Safety Basics

1-1 Using this Guide

This Safety Guide has been created so that students can safely and appropriately perform experiments, practical training, crafts, and other activities. General information on safety common to each department, such as what to do in case of accidents and disasters, and various warning systems are also discussed. Please read and be familiar with this guide, review relevant items before starting experiments, and use as a reference for dealing with accidents and emergencies.

1-2 Fire

1-2-1 Fire Prevention

Fire prevention is very important. When a fire occurs, the damage can be great, and lives, important equipment, materials, and data can be lost. It is important to have the proper attitude and knowledge to respond to any fire that may occur.

  • 　Prepare a fire extinguisher and fire extinguishing sand and confirm its location.
  • 　Never use fire in the places indicated as "Fire prohibited"
  • 　Minimize the amount of combustible materials used in the laboratory
  • 　Regularly examine gas hoses, and replace if damaged.
  • 　Use standard devices for organizing electric cords rather than random entanglement of wires.
  • 　Pay attention to electric leakage due to dust and dirt.
  • 　Confirm evacuation routes
  • 　Actively participate in firefighting training for fire protection / disaster prevention awareness

1-2-2 Fire Extinguishers

In corridors, "ABC powder fire extinguishers" and "reinforced liquid fire extinguishers" are alternately placed every 20 meters. The "ABC powder fire extinguisher" is effective for the initial extinguishing of A) ordinary fires, B) oil fires, C) electric fires. The "Enhanced liquid fire extinguisher" can be used not only for A) ordinary fires but also for B) oil fires. It is especially effective against oil fires. When the pin is removed and the lever is pulled, the fire retardant (a cooling-effect potassium carbonate aqueous solution mist) will spray out for 15 seconds. It is also effective for C) electric fires. Besides this fire extinguisher, others, such as reinforced liquid fire extinguishers and carbon dioxide fire extinguishers, may also be found in the laboratories. To use a fire extinguisher, follow these steps.

  1. 　Unplug safety pin
  2. 　Remove hose and aim at the source of the fire
  3. 　Squeeze lever firmly and spray

1-2-3 How to Use Fire Extinguishers

In addition, we also have the following firefighting equipment.

(1)Automatic fire alarm system 
Equipment that automatically detects smoke and heat and alerts people in the building of fire via an alarm bell. Every area and room in all buildings have "heat" sensors that automatically trigger fire alarms, and "smoke" sensors that are constantly monitored by the disaster prevention center and facilities control room receiver. Upon sensing smoke or heat, alarm bells and emergency broadcasts occur on that floor (fire floor) and the floor above it (just above the fire floor) and are transmitted sequentially to other floors. Floors in small buildings ring all at once. The reason forsetting this time difference is to avoid confusion during evacuation, especially in high-rise buildings

(2)Indoor Fire Hydrants 
Fire extinguishers are installed indoors to help extinguish fires. Their location is marked by a red lamp, or a green seal and instructions are written on the back side of the storage lid. Green seal extinguishers can be used by anyone with access. If possible, try of operate it with at least two people. Extinguishers without a green seal are for use only by professional fire fighters.
Please follow the procedure below.
1. Locate the "Press button" above the Green seal hydrant.
2. Break its clear plastic cover to push the button.
　 (A pump will start, an indicator light will flush, and an alarm will ring)
3. Open the door of the fire hydrant box
4. Hold the hose by the nozzle
5. Open the valve and spray water onto the fire

(3) Emergency broadcasting equipment
Emergency broadcasts will be made during emergencies or when otherwise needed. Speakers are attached to the ceiling, and microphones and amplifiers are installed in the Omiya Campus Central Monitoring Room, Toyosu Campus Disaster Prevention Center to broadcast messages to inform people how to respond.

(4) Fire Doors and Fire Shutters 
There are fire doors and shutters to prevent flames and smoke from spreading in corridors, elevator shafts, stairway entrances, and surrounding areas. Fire prevention doors are usually folded into the wall, but close automatically in conjunction with the sensor, so to escape, open the closed door briefly by hand.
※ Do not place objects in front of fire doors or shutters!

(5) Evacuation Guidance Lights
Green evacuation lights (displayed next to escape routes) are always shining, indicating the location of the emergency exit and the direction of evacuation. Each one has an emergency power supply (battery) so is lit for about 20 minutes even if there is a power outage. In addition, please make sure to note the escape route, and the evacuation direction indicated by the green sign which is not illuminated.

(6) Emergency lighting
Although it is attached to the ceiling, it does not usually shine, but in the event of a power failure it automatically switches to an emergency power supply and illuminates the evacuation route for about 20 minutes to help evacuate people from the building 

(7) Sprinkler 
When heat or smoke is detected, sprinklers automatically spray a large amount of water. Because they are always ready to spray water, please do not use hot plates under sprinklers.

(8) Elevator Control Operations 
1. Fire: At the time of a fire, elevators immediately go directly to the evacuation floor (1st floor), and after opening their doors once, elevators close and stop.
　※ The emergency elevator at the Toyosu Campus is used for firefighting and rescue work by fire brigades.
2. Earthquake: At the time of an earthquake, all elevators are forcibly stopped at the nearest floor. After the door is opened once, elevators close and stop.
　(Please press the "Open" button on the operation panel to open the door again from inside ※ )
　※ The escalator will not stop automatically in the event of a fire or an earthquake.

1-2-4 Initial Response to Fire

Anyone who discoverers a fire should "loudly" announce that a fire has been discovered. Please press the emergency button when the fire alarm does not sound. Try to
extinguish the initial fire with fire extinguishers, firefighting sand, etc. Please contact the appropriate campus office as indicated below.
Report example
"There is a fire. The place is ** building ** floor ** room, cause is **. There are no injured people (or * people are injured). Initial extinguishing is impossible. "
Omiya Campus Student Division Extension: 5105
Morning ward extension : 5101 · 5201
External line : 048-687-5101
External line : 048-687-5201
Toyosu Campus Student Division Extension: 7370
Disaster prevention center extension: 7280
External line : 03-5859-7280
Do not panic at the initial discovery. Eliminate the three elements that allow fires to spread: "heat", "oxygen" and "flame". Apply sand to the fire, lower the temperature, limit the oxygen by throwing a wet cloth onto the fire, remove flammable materials around the fire, and so on.

1-2-5 How to Treat Fire Injuries


  • If clothes should catch fire, use fire extinguishing methods such as applying water, smothering the flame with cloth, and rolling on the floor. When handling fire, it is best to wear natural fiber such as cotton or wool. Artificial fiber such a polyester can stick to the skin and cause serious burns.
  • Turn off the fire source such as gas valves, electric heaters, etc, and remove surrounding combustible materials.
  • Determine the presence of explosive or toxic gas
  • Oil and alcohol float on water and spread when water is applied, So use fire extinguishers to fight oil and alcohol—Don't be in a hurry to splash water on the fire. Individuals should not continue to fight a fire after it reaches the ceiling. After that please close the door of the room and loudly announce that everyone should evacuate promptly. If there is smoke, cover your nose and mouth with a handkerchief or cloth, and evacuate upwind by looking at the movement of the smoke while in a crouching position
  • Confirm if there are any people who need relief in the vicinity and work in cooperation with any people who are present

1-2-6 When an Explosion Occurs

If an explosion happens suddenly, causing an accident, please take the following actions:

  • First, provide assistance to those with major injuries
  • Find the device or chemical that caused the explosion and return it to its original condition so that a second disaster does not occur
  • If repair is difficult and there is danger of a secondary disaster, evacuate promptly
  • If a fire occurs due to an explosion, follows the Safety Guide fire procedures

1-3 Earthquakes

1-3-1 Knowledge and Preparation for Earthquakes

The Japanese archipelago is an epicenter for earthquakes, and a another big one is expected to occur
at any time. Earthquakes cause other simultaneous disasters, which may delay the
response of fire and police departments, so it is important to take precautionary
measures that can reduce damage by enhancing our state of preparedness:

●Create a safe working environment by taking preventative measures around you, as much as possible.
　- Create a safe place indoors in case furniture falls over or glass is broken.
　- Adopt practices that help prevent laboratory equipment and chemicals from tipping over or falling.
　- Prevent furniture from falling over by securing it to the wall.
　- Don't put heavy objects on high places, and tie down objects that move around easily.
　- Use shatterproof sheets on windows and closets to prevent damage.
　- Avoid displaying non-essential glassware, such as frames and memorabilia, as much as possible.

● Decide how to make contact with your famil
  • SIT will provide contact information via an emergency communication service such as the 'Disaster Message Service' or 'Disaster Message Dial'
  • SIT will designate an emergency meeting place such as an evacuation center.

● Stockpile minimum emergency food and supplies needed to maintain life
  • It is recommended to have a stockpile of food and water that will last about a week until an ongoing supply of food and water can be provided. At the university, we have a stock of water and emergency food for all two campuses, but it is also advisable for individuals to prepare their own from the viewpoint of "self-help" ※3 liters of water is required per person per day.
  • Individuals have different daily needs, so please stockpile any items you might need, such as allergy or regular medications

● Review the evacuation route and prepare for action after an earthquake
  • Review the route from the campus to your home, in advance. Based on their past earthquake damage assessment, the 2campuses are prepared to accommodate staff for up to 3 days in accordance with the Tokyo Metropolitan Government's measures to deal with the difficulty of returning home. After 3 days, we will adjust our response plan based on the scale of the earthquake, and on the time, and transportation situation. Please prepare to walk home at the usual time by keeping such items as a map and sneakers in your office.
  • At the Toyosu campuses, tsunami vigilance is also needed. Please evacuate to the upper floors of each building when a 'big tsunami warning' is issued

●Using the Earthquake manual

Please read the "Great Earthquake Response Manual" (normally distributed at orientation) and keep it nearby.

1-3-2 What is an ‘Alert Declaration’

In the event of a major earthquake occurrence, a declaration will be issued from the Prime Minister. Please pay attention to information on television, radio, and other media, and act according to the disaster prevention plan of each local government.

1-3-3 Dealing with an Earthquake

When a life-threatening event happens, it is important to remain calm.
Shelter under a desk for protection against falling belongings, objects, and to protect yourself from fire, hot water and chemicals.

  • There is no need to immediately extinguish fires during an earthquake. ※ It is dangerous to approach fires while shaking persists. The main jolt of most earthquakes is during the first minute, so please extinguish fires after the earthquake has subsided.
  • If inside an elevator during a quake, press buttons for all floors and immediately get out at the first stop.
  • When you are outside, beware of falling objects such as glass, protect your head and seek shelter inside a sturdy building

1-3-4 Evacuation and communication

It will take time to organize rescue, police, fire, and emergency response teams, so we need to work quickly and appropriately in cooperation with our colleagues and others who are present during the quake.

●Immediately after the earthquake
  • If barefoot, watch out for fallen glass, put on shoes and then act
  • Inspect the area for the occurrence of a fire and switch off the gas mains switch and electric appliances
  • In case of a fire, alert others nearby in a loud voice and work with them to fight the fire.
  • Evacuate by stairs (if you are on a higher floor, move to the lower floor after the earthquake has settled)
  • Consult radio and TV for accurate information
  • On the Internet, beware of information from unknown sources that may be based on ambiguous information or rumors
  • Reply to the safety confirmation e-mail sent to you by the university

●Until an organized relief system is in place
• SIT will strive to ensure accurate information to counteract hoaxes and false news
• Dial "171"to access the Disaster Message phone system and refrain from unnecessary communications as much as possible
• Heed university instructions to return home in a reasonable way (movement in the afflicted areas may be dangerous and difficult)

1-3-5 Designated evacuation areas in case of disaster

● Omiya Campus
At the Omiya campus, when a fire or earthquake occurs during class, disaster information will be broadcast throughout the premises to faculty and staff. The

evacuation areas are the athletic grounds and school bus parking lot. The toilets that can be used during power outages are in university hall (B1F music practice room, B1F central monitoring room front), Building No. 5 (except for the Mathematics Building), the library, and the multipurpose court.

● Toyosu Campus

The Toyosu campus has been designated as a "residual district within the district" by the Tokyo Metropolitan Government. When a fire or earthquake occurs during classes, information on the disaster will be broadcast to Toyosu campus faculty and staff, and information on evacuation sites will be designated.
All hallway toilets become unusable during power outages.
As a general rule, shelter locations for students, faculty, staff and others at the time of a disaster shall be as follows:
Students
Faculty staff
Main Building, 3rd to 6th floors
Regional evacuees who cannot reach home Gymnasium, Community  lounge , Cafe & Restaurant
●SIT stocks sufficient water and food for three days based on the regulation measures

1-4 First Aid

1-4-1 General injury precautions

  • Accurately determine the cause, type, and degree of injury (including name of substance or poison)
  • Early treatment is required for cardiac and respiratory arrest, loss of consciousness, massive bleeding, and poisoning
  • Do not give water to unconscious individuals, as it may clog the trachea
  • When foreign matter enters the eyes, rinse with running water without rubbing the eyes.
  • Always report to the supervising professor when finishing first aid measures and refer to the accident prevention measures in this Guide.
  • Regularly check the location of the first aid box and whether it has sufficient medicine
Direct contact numbers for the health counseling room (nurse's office)
Omiya TEL：048-687-5113
Toyosu TEL：03-5859-7400

1-4-2 First Aid Measures for Accidents

Initial response for victims who cannot move or are unconscious:
First ask the victim to provide information.　If there is no reaction, seek assistance from bystanders.

(1) If still conscious, move victim into a comfortable position
※If complexion is pale, place victim's feet in a raised position.
※ If face is red, elevate the upper body.
(2) If unconscious, establish a non-choking posture by tilting head slightly backwards so the lower jaw protrudes (to free airway)
※ If the victim can breathe without assistance, have them lay on their side.
  • If behaving strangely, do not shake, hit, or forcibly move
  • If complaining of abdominal pain, let the victim choose the most comfortable position
  • Loosen belts, neckties, clothes, etc. and keep warm with a blanket or other covering.

1-4-3 Trauma・Sprain・Fracture Treatment

Be careful not to miss symptoms such as fractures, which may have been caused by falling from a high place, falling down or being crushed by objects, even if there is no visible trauma such as bleeding.

  • When there is little bleeding and the wound is dirty, wash it with running water to clean the wound.
  • If bleeding does not stop even when you hold a clean cloth on the wound, press down on the artery closest to the wound with your fingers and raise the wound higher than the heart
  • Sprains occur by twisting joints by force, and dislocation occurs when joints are separated. Do not forcibly move sprain and dislocation victims.
  •  Orthopedic surgery may be needed to prevent permanent injury to the joints.
  • If you suspect a fracture, secure with splints before moving
※ Sew or tie the bandage at the elbow of the arm to be treated.

1-4-4 Treatment of Burns, Frostbite, Electric Shock

Serious electric shocks can be recognized by skin that is deeply discolored and carbonized. Please treat this area as you would a burn.

  • Light burns can be chilled with cold or ice water until the pain subsides.
  • If clothes are stuck to a burn, cut the fabric around the edge of the wound and do not forcibly remove it.
  • Do not break blisters or try to disinfect burns with ointment or apply gauze. Keep injured area cool until victim reaches the doctor's office.
  • If victim is injured and in shock, cover with a towel or blanket and keep warm
  • The affected part of frostbite should be soaked in hot water(about 40 degrees)for 20 minutes or more, then elevate the affected area (never strongly rub frostbit areas)
  • Because the scar due to the electric shock is deeper than it seems, transport the victim to a medical institution as soon as possible
  • Rescue victims of electric shock by first turning off the power so that the rescuer does not cause a secondary accident

1-4-5 First Aid for Gas Poisoning

  • Open the window when rescuing, and look for secondary disasters
  • Do not touch light switches. This could ignite flammable substances
  • Victims who are nauseous or pale may be in shock, so quickly move them to fresh air, keep them warm and allow them to rest.

1-5 Work Environment

1-5-1 General Principles

Working environments are a collection of various conditions such as temperature, humidity, air cleanliness, illuminance, light. It is important to keep these working environments in good condition so that accidents and disasters will not result.

1-5-2 Hygiene Standards for Work Environments

 (1) Temperature / humidity

In the laboratory, it is desirable to keep the temperature and humidity at an appropriate level according to the content of the work, seasons, etc. However, unlike in most offices, there are certain procedures and equipment that can cause discomfort. Temperatures that do not physiologically and psychologically stress workers are 18 to 20°C in winter, about 25 to 28 °C in summer, and about 50 to 60% in favorable humidity conditions.

(2) Air / ventilation

In the laboratory, concentrations of suspended dust, carbon dioxide, etc. in the air may adversely affect workers. Also, although it is common to use a draft
chamber or push-pull ventilator to protect people from things such as harmful chemical substances, lead and organic solvents, be aware of what the required safe concentration level is for such airborne substances in the working environment. Since the hygiene standards for offices is already defined, it is shown in Table 1 for reference.

Table 1. List of Office Hygiene Standards  
Item  Criteria 
Air environment  Volume  10 ㎥ / 3 or more persons 
Windows and other openings  When the maximum area of the vent opening is constantly not less than 1/20 of the floor area (providing a ventilation establishment when less than 1/20) 
Environmental standard of indoor air  Carbon monoxide  50 ppm or less 
carbon dioxide gas  0.5% or less 
Temperature  When it is less than 10 ℃  Perform measures such as heating 
When air conditioning is on  Not significantly lower than ambient temperature 
(The difference from the outside temperature is within 7 ° C) 
Air conditioning equipment  Supply air cleanliness  Floating dust volume (10 micrometers or less)  0.15 mg / m 3 or less 
Carbon monoxide  10 ppm or less 
carbon dioxide  0.1% or less 
Formaldehyde  0.1 mg / m 3 or less 
Standard of indoor air  air flow  0.5 m / s or less 
room temperature  Try to 17 ° C to 28 ° C 
Relative temperature  Try to 40% or more and 70% or less 


(3) Daylight / artificial lighting

Provide adequate illumination -- taking into consideration such things as the degree of natural light, indoor color, and the type of light source. The required degree of illumination is specified in JIS 's illuminance standard (Z9110 - 1979), as shown in Table 2 below.

Table 2. Illuminance required by JIS (for factories): may be obtained by local lighting at the location of the work marked with a circle. 
Illuminance lx  place  Work 
3,000 to 1,500  ○ Instrument and control panels in such places as control rooms  Precision machinery, manufacture of electronic parts, extremely detailed visual work at printing factories. For example, ○ assembly, ○ inspection, ○ test, ○ selection, ○ design, ○ drafting 
1,500 to 750  Design rooms, drawing offices  Sorting in textile factories, inspecting, typesetting in printing factories, proofreading, analysis in chemical plants, etc. Detailed work such as assembly, inspection, ○ testing, ○ sorting 
750 to 300  Control rooms  Ordinary visual work in general manufacturing process, etc. such as ○ assembly, ○ inspection, ○ testing, ○ selection, ○ packaging, ○ office work warehouses 
300 to 150  Electrical rooms, air-conditioning machine rooms  Coarse visual work, such as ○ Limited work, ○ Packaging, ○ Packing 
150 to 75  Exit / entrance, hallways, aisles, stairs, washrooms, toilets, warehouses  Very coarse visual work, such as ○ ○ limited work, ○ packaging, ○ packing 
75 to 30  Indoor emergency stairs, warehouses, outdoor power plants  ○ Work such as loading, unloading, moving loads 
30 to 10  Outside (alleys, security guard posts) 


(4) Noise and vibration

Noises are unpleasant, and often hazardous by interfering with conversation or signaling, and can also cause hearing loss. This is especially true of sounds concentrated in large sounds and narrow frequency bands (pure tone), high frequency sounds, steady sounds over long periods of time and those over the saftey criterion of 85 decibels (dB). If you cannot prevent noise, please use earplugs. Table 3 shows the standards and guidelines for noise levels for reference.

Table 3. Noise value standards and guidelines
Estimated 1 (noise type)  Approximate 2 (physical / life impact)  Noise level (dB)  Noise source and distance (standard of size) 
Extremely Noisy  Hearing dysfunction  120 dB  · Near a jet engine 
110 dB  · Near a blaring car horn (2 m) 
100 dB  · Very close to a passing train 
It's so noisy I cannot bear it  90 dB  · In a noisy factory 
８０dB 80 dB  ・地下鉄の車内 · Inside the subway car 
Noisy  I cannot have a conversation unless I raise my voice  70 dB  · In a noisy office 
· Noisy street 
If you raise your voice, you can be heard  60 dB  · Quiet passenger car 
· Ordinary conversation 
Typical  Normal conversation is possible  50 dB  · Quiet office 
There is no hindrance to audible conversation  40 dB  ·Library 
Quiet  Sounds are very few  30 dB  ·Late night in the suburbs 
I hardly hear any sounds.  20 dB  · Tree leaves rustling 

1-5-3 VDT Operation

The IT environment has changed the workplace in such a way that our constant use of VDT (Visual Display Terminals) has created a number of common maladies:
(1) VDT disorder - VDT syndrome (symptoms include, dry eye, congestion, impaired vision, and eye strain)
Symptoms include cervical shoulder syndrome (key puncher's disease), stiff neck, waist and shoulders, chronic back pain, and numbness of the fingers.
Psychological symptoms include loss of appetite, irritation, anxiety, depressive symptoms
(2) Preventive Measures
1) Environmental management
It is important to prevent proper lighting, lighting and glare prevention, noise reduction, proper chair and desk for proper working posture, adjustment of VDT equipment etc.
2) Work management
Continuous working time should not to exceed 1 hour: Set a break time of 10 minutes to 15 minutes between each work period, and take short breaks once or twice within each work period.
