5.6 Rechargeable Battery Packs and Chargers

  1. This set of guidelines applies to rechargeable battery packs (“battery packs”) and the related chargers (“chargers”), including those of electric hand tools, used in IW. It does not apply to cylindrical batteries as well as batteries used in mobile phones and laptop computers.
  2. Only battery packs and chargers from trustworthy brands and suppliers can be used in IW. You can consult the technical manager for a list of these brands and suppliers.
  3. All battery packs and chargers must be registered with the IW Office before being used in IW. A label, to be stuck on the registered item, bearing the IW stamp will be issued by the IW office for identification purpose.
  4. Battery packs can only be charged in the charging cabinet provided by IW (to be implemented after the arrival of these cabinets).
  5. Charging of battery packs in IW outside its opening hours is prohibited. Power supply to charging cabinets will be shut down half an hour before IW closes.
  6. Excessive charging current may damage the battery pack and lead to safety issues. Unless the charging current limit of the battery pack can be detected by the charger through, typically, the balance plug/port/connect, the charging current limit must be correctly set manually in the charger.
  7. Battery packs with ageing, abuse and faulty signs should not be used in IW. These signs include but are not limited to deformations of the battery cases typically due to swelling and dropping, excessive wearing of the battery cases, batteries running out appreciably quicker than normal, and charging appreciably slower than normal.
  8. Faulty and partially faulty chargers should not be used in IW.
  9. Each project team should keep its list of battery packs and chargers. A monthly statement should be submitted by the project team leader to the IW office to confirm that each of the battery packs and chargers is in good condition, see 7 and 8. The statement should also be endorsed by a technical staff.
  10. IW staff should be notified immediately when the alarm of the charging cabinet rings; the battery pack and/or charger produce smoke, hissing sound and/or on fire regardless of whether the battery pack is being charged. The University’s Security Control at 3917 2882 or even 999, if applicable, should then be contacted unless the staff is sure that the situation has been under control, e.g. the smoke, hissing sound and fire have essentially stopped. Users and staff should stay away from the incident location until the smell, smoke and fire, if any, have gone out.
  11. Useful information on battery packs and chargers can be accessed at Lipo Battery Guide and Understanding LiPo Batteries.

5.7 Work-above-ground and Work-at-height

In general, work-above-ground and work-at-height mean carrying out the work at less than and above 2 metres above the ground/floor level, respectively.

Ladders, including straight ladders and folding ladders, are usually used for ascending and descending purposes only. They should not be used for work-above-ground unless in very exceptional circumstances and after having conducted a task-specific risk assessment by the Technical Manager. If the use of ladders is unavoidable, stringent control should be implemented to ensure that adequate and suitable control and safety measures are in place. In particular, another technical staff should stay on the ground/floor level to prevent the ladder from being hit or struck by moving persons and objects.

In InnoWing, only full-time technical staff trained in using its working platform are allowed to work-at-height and the working platform must be used. Another staff should stay on the ground/floor level to prevent the working platform from being hit or struck by moving persons and objects.

  • When a working platform is being moved to another workplace, do not allow any persons to stay thereon, any objects that may increase the risk of overturning the platform and loosen objects that may fall while moving the platform to be placed thereon;
  • All the castors should be firmly locked in position while ascending/descending and using the working platforms;
  • The outriggers of working platforms should be fully extended in accordance with the manufacturer’s requirements to ensure their secure foundation and stability.
  • The height-to-base ratio of mobile working platforms and other safety recommendations in the manufacturer’s manual should be strictly followed. Do not arbitrarily increase the height of mobile working platforms beyond the manufacturer’s recommended level.
  • The working platform should be properly maintained, examined and inspected in compliance with the statutory requirement. The relevant records should be made available in visible locations of the working platform.

More safety guidelines on the working platform can be seen at http://www.safety.hku.hk/homepage/pdf/WPSG.pdf.

5.8 Safety Quiz and Training for Students

To access the facilities in InnoWing, students must first become a member and pass a safety quiz: https://innowings.engg.hku.hk/membership/.

To access any particular equipment items, students must have gone through the appropriate training and have been assessed by the Technical Manager. Examples of the training include the engineering/workshop training courses offered by engineering academic Departments of the University. InnoWing also offers its in-house training and/or supervision on operating the equipment items of the InnoWing, see https://innowings.engg.hku.hk/membership/#rules.

5.9 Student Interest Group Working (SIG) Outside Opening Hours

Under exceptional circumstances, SIGs may request access to the project studio only (but not the open area) outside normal opening hours by applying to the Office. The application must be endorsed by the academic supervisor, who will be responsible for arranging supervision or monitoring. Supervision may be conducted by the academic supervisor, a technical staff member, or a tutor. If a technical staff or a tutor is proposed for this role, special endorsement from the Director of the Tam Wing Fan Innovation Wing is required.

The application will be reviewed by the Director and the Innovation Wing office following the academic supervisor’s endorsement. The final decision on approval rests with the Director and the Innovation Wing office.

To ensure compliance, the Office may conduct spot checks, including reviewing CCTV footage, to verify the activities of the SIG and the presence of the supervising staff.

To optimize resource utilization, approved access will be granted for a specified minimal period during the academic year, as determined by the Innovation Wing. The Director and the Office reserve the right to suspend or deactivate access rights for working outside opening hours at their discretion.

Please note that the terms and arrangements for such access are subject to change without prior notice.

8. Reporting Incidents and Injuries

Incidents here refer to health and safety-related accidents, injuries, near misses, repeated violations of safety regulations, etc. All incidents must be reported to a technical/office staff who should then notify the Technical Manager or the Director as soon as possible. The technical/office staff should note down:

  • (i) time and date of the incident,
  • (ii) location of the incident,
  • (iii) name(s) of student/staff/visitor involved,
  • (iv) staff-in-charge of the incident location,
  • (v) a brief description of the incident,
  • (vi) medical treatment and medical leave,
  • (vii) nature of the incident (e.g. accidents, injuries, near misses, repeated violations of safety regulations), and
  • (viii) telephone number of the relevant person(s).

The Director needs to report any work-related injury (including those on outsiders) leading to temporary or permanent loss of work capacity to Human Resources Section of the Registry and the Safety Office. In practice, it may be difficult to judge whether a minor injury leads to any loss of work capacity. So the policy of the University is that staff, students and visitors are encouraged to report all work-related injuries. In particular, the injured MUST notify the InnoWing if he/she sought medical treatment from any hospital, medical clinic or practitioner no matter how minor the injury is.

For emergency, the University’s 24-hour Security Control Centre at 3917 2882 or even 999, if applicable, should be contacted directly.

11. Guidelines on Safe Pest Control Operation

Cases have occurred in Hong Kong in which the health of people has been seriously compromised by pesticides which are by nature toxic chemicals. It is therefore essential to ensure that people are not unduly exposed to pesticides via inhalation, ingestion and/or skin absorption. Fumigation is generally not allowed on campus unless it can be established that it is the only effective method for a particular task.

If staff and students are repeatedly annoyed by pests, please report to the General Office which, at its discretion, can contact the Estates Office for assistance.

More comprehensive guidelines on pest control operations can be seen at www.safety.hku.hk/homepage/pdf/PestCont.pdf.
