CODE OF PRACTICE FOR
CEILING DUST REMOVAL
GENERAL
GUIDELINES FOR CEILING DUST REMOVAL
Ceiling dust,
in houses and buildings constructed before 1970, is generally contaminated with a variety
of minerals, which are dangerous to health. Lead is particularly dangerous to children and
is found in high levels in ceiling dust in houses and buildings near busy roads,
industrial areas and dense city areas.
This dust
should be removed for the sake of the health of occupants and any potential workers.
Because of its very nature, the dust, if disturbed, can be easily spread to all parts of a
building. The extent of dust removal will be dependent on the extent of the disturbance
and proposed usage of the space following the work.
REASONS
FOR TOTAL DUST REMOVAL: -
- Demolition of ceiling or cavity
walls;
- Installation of an attic ladder;
- Addition of a second storey
extension;
- Installation of insulation, new
electrical wiring, ceiling ventilation, fan etc;
- Dust leakage through wall vents
and ceiling vents;
- Dust leakage through tongue and
groove timber ceilings.
REASONS
FOR PARTIAL DUST REMOVAL: -
- Installation of a skylight,
light fitting, etc;
- Dust leakage through cornices,
picture rails, skirting boards, architraves, window and door frames, fire places and the
like;
- Future storms or other trauma
which could damage the ceiling.
The removal of
the dust is a hazardous procedure for the workers and the occupants and so strict
procedures and guidelines should be followed.
PROCEDURE
FOR REMOVAL OF DUST
Ceiling dust
removal should be completed before any other building work involving penetrations into
ceilings or walls is carried out.
The removal
should only be carried out by experienced Contractors who can show proof of their
competency, eg have a Certificate from a training course accredited by ADRA (Australian
Dust Removalists Association Incorporated).
Before
commencing removal from ceilings or walls, all vents, cracks or fissures should be sealed
to ensure contaminated dust is not spread to other parts of the building.
GUIDELINES
FOR CONTRACTORS
he contractor
shall adhere to the following general guidelines for ceiling space decontamination: -
- All contractors are required to
exercise relevant OHS procedures to comply with the relevant NSW WorkCover Authority
legislation.
- All occupants should be advised
to vacate the premises during the ceiling dust removal. Children in particular should be
absent during the work.
- At the time of quoting, the
contractor could furnish to the homeowner, a fact sheet on ceiling dust by THE LEAD GROUP.
- All employees directly involved
in the removal should wear, at all times, personal protective equipment conforming to
AS1716 (Respiratory Protective Devices) and be sufficiently trained in their use. They
include masks, hooded overalls and gloves.
- All employees directly involved
in the removal should undergo personal biological monitoring for exposure to contaminants
in ceiling dust and records should be kept.
- All dust should be removed by
HEPA filtered vacuum cleaners. The cleaning unit and the dust collection system would
preferably remain external of the building.
- Dust should not be swept or
shovelled into bags.
- Removal of the dust should start
from the roof entry point and work should be continued from there towards the edge of the
ceiling so as to minimise the disturbance of the dust.
- All collected dust should be
contained in sealed drums or 200um (micrometre) plastic bags and transported under EPA
guidelines and disposed of at an EPA licensed waste facility.
- All employees involved in dust
removal should adopt good hygiene practices and ensure hands and faces are thoroughly
washed often and prior to smoking or eating.
- Smoking should not be allowed
within the confines of the premises.
- All employees entering the
ceiling space within one (1) hour of dust removal should wear approved respiratory
protection conforming to AS1716.
- Personal decontamination
procedures are to be followed including disposal of used overalls with the dust and
washing hands and face with clean water outside the building before leaving the site, with
all waste water directed to the sewer.
- All Contractors should have
Certificate of Currencies for a minimum public liability cover of $5,000,000 and relevant
workers compensation insurance.
QUALITY
CONTROL ASSURANCES: -
That the
ceiling dust removal Contractor: -
- Be credited by ADRA and follow
the Code of Practice for Ceiling Dust Removal.
- Ensure workers are covered by
WorkCover requirements.
- Dispose of contaminated dust in
handling procedures, transport and disposal in accordance with EPA Guidelines on
Classification and Management of Waste.
- Use of best practice including
prior site inspection, adequate supervision of workers and full disclosure of issues to
the client.
