3.0 RESPONSIBILITIES
3.1 Supervisors are responsible for:
a) ensuring that any worker using lead or generating lead dust, fumes, and mists
understands the hazards of lead exposure and the controls necessary to protect
themselves; and
b) ensuring that workers under their supervision are trained in accordance with this
procedure.
3.2 Project Managers are responsible for:
a) ensuring that contractors’ work that may release lead dust, fumes, and mists into
the workplace is performed in accordance with this procedure and Ontario
Regulation 490/09; and
b) notifying the principal/building managers of any work being performed by
contractor that may create a risk of exposure to lead.
3.3 Occupational Health and Safety Division is responsible for:
a) maintaining this procedure; and
b) ensuring this procedure is reviewed by the Joint Health and Safety Committee at
least every three years.
3.4 Workers will be responsible for:
a) performing their work in a safe manner, in accordance with the training and safe
work procedures provided to them.
4.0 PROCEDURES
4.1 Prior to any work being done by any worker that could result in exposure to lead, the
worker shall consult the Designated substance Survey a vailable in the Chief
Custodian’s office. The Designated Substance Survey provides information about the
location of materials at the site which are known to contain lead, and other designated
substances regulated under Regulation 490/09, Designated Substances.
4.2 Alternatives to lead-based products must be used where practicable to reduce the
potential for exposure to lead. Products that may contain lead, such as paint, shall only
be purchased through the district’s approved procurement processes to ensure they
meet appropriate safety standards.
4.3 Lead-containing materials or products in their hardened state must not be crushed,
ground, scraped, filed, sanded, cut, heated, welded, soldered or otherwise shaped by
any means without procedures for reducing exposure to the released lead dust, fumes
and mists.
4.4 Lead-containing waste, including accidental spills, must be handled carefully to
minimize the production of airborne dust.
4.5 Clean-up shall be performed with vacuums fitted with HEPA filters to prevent the
generation of respirable dust particles.
4.6 Compressed air will not be used for cleaning lead-containing material under any
circumstance.
3 PR.693.HS
4.7 Staff involved in the clean-up of lead spills will wear personal protective equipment as
required.
Control Program/Classification of Work
4.8 Where work is being undertaken that could result in exposure to lead, the following work
