Urban Blasting Recommendations
· As a result
of a number of problems with flyrock on construction
projects in BC, we held a discussion regarding striking a
committee to look into setting recommendations for best
industry practice guidelines for urban blasting.
·
Pat McLaughlin has concerns that the clients of blasting
firms have to be willing to pay more for blasting work in an
urban area. We need to educate the developers that there is
value in adopting best industry practice guidelines. To be
sure, municipalities will be looking to adopt these
guidelines for blasting in their jurisdictions, and some of
our guidelines may become law. We need to be careful with
recommendations and carry out a parallel education program.
·
Paul Jeannotte said that where this started was with the
Mayor of Langford, BC who is promoting this issue, because
the alternative is the public wants to ban blasting in his
municipality.
·
Alastair mentioned that in the Victoria area, there have
been a number of flyrock incidents, and there is public and
regulatory pressure for industry to take action and come up
with recommendations.
·
Ed Taje mentioned that in BC, blasting in mines is regulated
by the BC Ministry of Energy and Mines who is looking at
restrictions on Mine Blasting within 1 km. of urban areas.
They are currently asking mining companies for input. In
the SW Region, there have been mining operations that were
shut down for up to 8 months due to flyrock problems. The
best way they have found to regulate the industry is to hit
them in the pocket book. They are also requiring blasters
to be licenced for urban blasting.
·
Stan Holtby stated that the blasting insurance companies
would be a driving force behind adoption of the guidelines
within the blasting industry. Stan feels that
municipalities will not sign off on blasting guidelines for
fear of accepting responsibility if things go wrong.
·
Paul Jeannotte mentioned that the City of Langford, BC has
asked that a Blasting Engineer sign off all blasting plans.
·
Alastair Grogan said that at the end of the day, when
something goes wrong, everyone gets named in a lawsuit.
·
Dave Hudak mentioned that ultimately, it is the “Blaster of
Record” who is responsible in the event of a blasting
accident.
·
Ron Elliott mentioned that if there were best industry
practices guidelines in place this could help the blasters
who are being asked to push the button on a shot where they
were not in favour of the way it was designed or loaded, but
must suffer the consequences when things go wrong. A number
of blasters have been in this situation and have lost their
blasting tickets. There is nothing the blaster can do but
walk off the job. If best industry practice guidelines were
in place, at least a blaster could refer to the guidelines
and say “this is the way I want to carry out the blasting
operation”. Right now he has nothing to back him up when a
company says that this is the way they require the blaster
to do the job.
·
Gary Kreller asked how many of those present are blasters.
He said that blasters who are working in an urban area have
a responsibility to do the job right and ensure that all
precautions are being taken. Gary gets calls from
Municipalities all the time looking for some assistance.
The WCB is there to enforce the regulations. Lack of
communication with the neighbours is a major concern, lack
of proper PR. Being pro-active and forming a committee to
set recommendations would be a big help to give
municipalities some of the guidelines they are looking for.
·
Ron Elliott said that the consensus seems to be that this is
a good idea. We would have to look at who would want to be
a part of this committee. We should recommend to the Board
of Directors that a committee be set up.
·
Dave Hudak said we should send out notices to the membership
asking who would like to participate on such a committee.
They need to be prepared to dedicate time to this and be
prepared to sell it, once the guidelines are established.
·
Alastair Grogan said that in the USA, there are a number of
jurisdictions where not only the blaster is held responsible
for a blasting accident, but the company is also held
responsible.
·
Dave Hudak mentioned that even if we set up recommendations
for “Best Industry Practices”, there is no guarantee that
they will be followed. We are not legislating anything and
this will not eliminate rogue operators who do not wish to
follow the guidelines.
Dave also recommended that we set up a
section of our WEB Site as a Blaster’s Forum to get feedback
from our members on issues such as this. This does not cost
us anything.
·
Ron Elliott said that we could also send out a letter to
members to gain their feedback.

Post Blast Fumes
Pat McLaughlin
mentioned that in blasting of wet areas, production of
Nitrous Oxide fumes is a problem. He wants to hear from the
manufacturers present, what is being done to prevent this.
·
Terry Matts said there is no simple solution to the
problem. Often, lack of confinement is the culprit. Bulk
emulsion getting into cracks and then deflagrating is also a
partial cause of incomplete detonation resulting in
production of NOx fumes.
·
Lyle Workman stated that the problem is more prevalent with
emulsion blends than straight emulsion. In the strip coal
mines in Wyoming, this is a major problem.
·
Ron Elliott mentioned that the addition of aluminum or urea
to the explosive has helped somewhat to control NOx, but
that this also drives up the cost of the explosive, and many
customers are not interested in paying the premium to
eliminate what they perceive as a minor issue. |
