Survey on School Laboratory Accidents (2005/06)
  • CM No.193/2006
  • http//cd.emb.gov.hk/sc_survey
  • input the data on or before 30 Nov 2006

6
Why accidents happen?
Inadequate Safety Training
Inadequate Instructions
Careless
Unsafe Experiments
Over crowding
Inadequate Facilities
Inadequate Equipment
Inadequate Preparation
Misbehavior
Ignorance
Teaching Experiences
Poor Laboratory Management
7
Education Regulation 279A (21)
  • The responsible person shall ensure that all
    necessary safety precautions are adopted in
    school workshops and science laboratories and
    shall modify or extend those precautions as the
    Permanent Secretary may require.

Science Teachers Legal Liability
  • If an accident and injury occurs during a science
    class, a science teachers legal liability for
    that injury will be judged by considering some of
    the following criteria
  • Did he/she use appropriate activities for the
    grade level?
  • Did he/she give careful instruction of all
    aspects of the activity?
  • Did he/she teach safety rules, and satisfy
    himself/herself that the students understood the
    activity and safety requirements ( safety tests
    are helpful)?
  • Did he/she carefully supervise the activity?
  • Did he/she strictly enforce safety rules?
  • British Columbia

9
Managing Laboratory Safety Effectively
  • Ensure objectives are met and to seek improvement
  • Safety Policy
  • Commitment of management in improving safety
  • Defines procedures and areas of responsibility in
    order to promote safe working for students and
    staff
  • Reviewed and revised regularly

10
Responsibilities in maintaining a safe learning
and working environment
  • Who should be responsible?
  • Students
  • Teachers
  • Laboratory Technicians
  • Panel Chairpersons
  • School Authority
  • Safety is Everyones Responsibility
  • Have you perform your duties? (????????)

Accident Case10/2001
11
Students
  • Know and follow all safety rules
  • Be alert in the laboratory
  • Do not attempt unauthorised activities
  • Exercise proper experimental techniques
  • Consider the safety of oneself and the others
  • Read and study lab manual before coming to class
  • Report lab accidents to teacher immediately
  • Keep area clean.
  • Proper disposal of biological and chemical waste.
  • Do not enter preparation or store rooms

Accident Case5/2000
Safety Rules
12
Teachers
  • Ensure the safety of all practical activities and
    must be thorough in preparation
  • Try out experiments in advance
  • Check that technicians know how to carry out
    safely the requested hazardous operations
  • Issue students with safety rules and explain what
    they mean and why they are necessary
  • Give clear instructions to students and remind
    them of the potential hazards and safety
    precautions
  • Provide sufficient supervision and guidance to
    students during experiments
  • Insist students to use proper PPE
  • Never leave students unsupervised in the lab
  • Familarise with the operation of safety
    facilities and emergency procedures

13
Panel Chairpersons
  • Set and model high standards of safety
  • Raise everyones concern on safety
  • Ensure all panel members provide adequate safety
    instructions and equipment to students
  • Be well informed of laws, rules and regulations
    concerning safety, assist school principal in
    formulating and implementation of safety policy
  • Co-ordinate the provision of safety resources /
    facilities
  • Organize/co-ordinate professional development on
    safety
  • Access and disseminate up-to-date safety
    information to teaching and technical staff
  • Keep a record of all accidents and details of
    treatment given
  • Develop and implement a regular schedule for
    safety inspection

14
Laboratory Technicians
  • Have responsibilities for each others safety and
    should warning each other of hazardous situations
  • Co-operate with safety policies of panel, school
    and EMB, etc.
  • Prepare, operate and maintain apparatus and
    equipment
  • Procurement of stores and equipment
  • Tryout experiments
  • Provide assistance in class demonstrations
  • Assist teachers in supervising students
    performing experiments
  • Observe all the normal safeguard in a laboratory
  • Familarise with the operation of safety
    facilities and emergency procedures
  • Check regularly to ensure all safety measures are
    in place
  • Supervise the work of other LTs / laboratory
    attendants

15
School Authority
  • Ensure school complies with the Education
    Ordinance
  • Builds up an effective management system
  • Draw up safety policies, administrative and
    operational procedures
  • Set up an accountability mechanism for such
    policies and procedures including how to handling
    emergencies
  • Provide necessary safety facilities and equipment
  • Support professional development on safety

16
Safety Procedures/Plans
  • Includes
  • Emergency procedures
  • How new staff are to be inducted?
  • How students are to be trained in safety
    awareness?
  • How should safety equipment be kept?
  • How new safety information are disseminated?
  • In what circumstances non-scientists may use
    laboratories?
  • How safety matters get onto the agenda of
    departmental meetings?
  • What procedures for risk assessment are to be
    adopted in open-ended investigations or project?
  • Event ? Procedure ? Effective result

17
Online Laboratory Information Management System
  • Accidents occurred
  • Experiments in different levels and subjects,
  • Booking of laboratories, inventory of relevant
    documents and equipment

18
Reporting of Laboratory Accidents
19
Promoting Safety Awareness
  • The most effective way to eliminate accidents
  • Develop and maintain safety and health awareness
    among all students and personnel
  • Recognize and promote safe work practices and
    reinforce positive attitudes towards safety
  • General and specific safety rules

  • On-line and CD-ROM versions
  • http//resources.emb.gov.hk/ses

23
Learning and Teaching Resources on Safety in
Science Laboratories
  • Laboratory Safety Rules
  • Eye Protection
  • Safety Information on Chemicals
  • Risk Assessment

    (discussion activities)
  • http//cd.emb.gov.hk/sci

24
Are your experiments safe?
  • Teachers must be careful when selecting
    experiments from various sources, especially
    older books and laboratory manuals prepared by
    others, etc.
  • As needed, teachers should consult science
    journals and publications to keep current on
    safety techniques
  • Discuss with your colleagues including science
    teachers and laboratory technicians

Risk Assessment
  • No experiment is completely safe and without risk
  • Any experiment worth doing is worth doing safely
  • Do it this way, rarely say Don't do this

27
Risk Assessment
  • An analysis of a practical activity to identify
    hazards and to take precautions to minimise the
    risk
  • Procedures
  • Identifying hazards (Materials / Procedures /
    Equipment)
  • Assessing how likely the hazard will actually
    cause harm (risk)
  • Deciding what control measures to reduce risk to
    acceptable level
  • Finding how to dispose of hazardous residues
  • Review

28
Reducing the Risks
  • Using safer alternatives
  • Modifying experimental procedures
  • Reducing the scale of experiments
  • Reducing the concentrations of solutions
  • Using protective measures
  • Wearing appropriate PPE

29
Thermometer
  • Digital thermometer
  • No-roll thermometer sleeve
  • Break-safe thermometer (encased in a PVC coating,
    10-100oC)
  • Low toxicity non-mercury filled thermometer, max
    110 / 330oC

31
Monitoring and Review
  • See whether management system and practices is
    working as planned and risk control measures are
    effective and maintained
  • Enquiries at departmental meetings
  • Discussions with teachers/LTs/students
  • Schemes of work, student worksheets, laboratory
    request forms, accident records, etc.
  • Occasional lesson observations
  • Safety Inspection /Audits
  • Keep record of monitoring e.g. inspection
    checklists
  • Standing Committee on Laboratory Safety
