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 battering 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.

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 be
gone thru the appropriate training and have 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 outside Opening
Hours

Under exceptional circumstances, Student Interest Group may
apply for working in the project studio outside the normal opening hours by
filing an application form obtainable from the General Office. The form must be
endorsed by the academic supervisor who must arrange himself/herself, technical
staff or tutor to supervise/monitor the activity of the group. Special
endorsement of the Director is needed if a tutor is proposed to supervise/monitor
the activity.

6. In-house Inspection System

In-house Inspection is conducted at approximately 6-month
interval by the Safety Working Group. A report would be furnished by the Group
for each Inspection and disseminate to all the staff-in-charge and technicians-in-charge.

7. Safety Vetting for Activities

An application for hosting activities in various Project
Studios, Thematic Workshops and Event Halls must be raised by the activity
supervisor who must be a teacher in the Faculty of Engineering. The application
would be vetted by the Safety Working Group to ensure the technical and safety
issues, if any, would be adequately addressed.

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, (v) nature of the incident (e.g. accidents,
injuries, near misses, repeated violations of safety regulations) and (vi) 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.
