About Lock Lock Setting

The Safety Security Management System is designed to be regularly updated to the latest information by linking with the following computer system to improve the accuracy and effectiveness of information.
- Academic Affair System: Info. on the persons engaged in research activities
- Space management system: Laboratory info., full-time persons who engage in research activities, information on the equipment to manage

The Lock function should be set not to automatically update the laboratory information or informationon the equipmentto manage

Laboratory Safety
Ventilation Hood
  • A researcher must conduct an experiment that generates toxic gas in a hood.
  • fume hoodfume hoodfume hood
  • Safety checkpoint

    A hood should be frequently checked if it is operated well. At least twice a year, its wind speed should be checked by using a gauge. Simply, attach a tissue paper on a hood window
    and check if it is well sucked in. A hood should have a proper face velocity to effectively extract toxic substances.

    • - Recommended wind velocity fpm(feet per minute)
        70~100 fpm: For general use (slight toxic materials) / 150 fpm: For special use (very toxic materials such as carcinogens)
    • - Tissue paper, etc. should not be in a hood. If it is sucked into the hood, it may block the airflow inside the hood and the hood may not work properly.
    • - Reagents should not be stored in a hood. If there are many reagents in the hood, the air does not well flow inside the hood.
    • - As the hood chassis does not protect people from strong explosions, before an experiment with a risk of the explosions is conducted,
        the researcher should install a safety shield inside the hood.
    • - A hood is not a place where waste is stored. After experiments, clean the hood.
Biological safety cabinet
  • A biological safety cabinet (BSC) is used to protect researchers from the particles or aerosols generated from laboratories that handle microorganism.
  • Use of, management of, and precautionary measures for biological safety cabinets
    • - A BSC is equipped with a High Efficiency Particle Arrestor (HEPA) filter.
    • - As a HEPA filter cannot filter gaseous compounds like organic vapors and these organics easily block the filter,
        it should be inhibited to experiments with organic matters in a BSC.
    • - A wind velocity to the outside should be well balanced with that from the outside to the experiment place.
Ultraviolet Rays and Laser Device
  • Ultraviolet rays and lasers are fatal to the eyes. A researcher must wear safety equipment and protective gears before exposing oneself to ultraviolet rays and lasers.
  • Cautions when using ultraviolet rays and laser
    • - In a laboratory where lasers are used, a laser sign should be attached. When using lasers, an indicator should be turned on.
    • - A researcher should wear safety glasses to protect his/her eyes from the light with the wavelength used.
    • - DO NOT look straight onto lasers.
    • - Do not place an object that can reflect light on the path where the beam is passed.
    • - Experimental equipment should be fully blocked so that ultraviolet rays are not scattered directly or by diffraction.
    • - Do not expose your skin to ultraviolet rays.
