I received this post from Melody Chamberlain who has spent 15 years as a caregiver and 10 years working in the vehicle modification industry. There is a wealth of information here and she has graciously provided her email address for anyone that might want any further information. I would encourage everyone to check out this website and view the crash test videos. I believe these should be mandatory part of training for both bus drivers and any other staff who are securing students in wheelchairs or other mobility aids. Of particular note is the information about the forces involved in a relatively slow one vehicle crash. I have placed the link to the site on the right hand side of this blog.

You are right Barbara,
it is not rocket science, but there is an awful lot of science that goes into
safe transportation. Most may not know
the laws, standards, and best practices that make transportation for those with
special needs safer, and fewer still actually practice these concepts on a
daily basis. Not out of lack of care
(for the most part - of course there are the rare exceptions), but from lack of
knowledge. I'll try to highlight some of
those laws and issues so that others (particularly parents) can be informed.
For School District
Transportation in BC, there are three main laws/standards that come into
play. First, Canadian Standards
Association (CSA) has two standards that school buses must meet: CSA D-250 and
D-409 (D-409 only if the bus is for transportation of "people with
physical disabilities" (CSA language not mine). I won't give a link for D-409 as it is a
purchase only site, but if you want to purchase search for CSA, then search for
D-409-02. This standard lays out the
requirements that vehicles must meet, including the minimum size for each
mobility aid position, the type and location of the MASOR (mobility aid
securement and occupant restraint) system and other requirements such as safety
and lighting. It also cross-references
to another CSA standard, namely Z605 which lays out the standards the MASOR
system must meet to be considered legal and safe for use in Canada. If the restraint system is not labeled as
Z-605 compliant DO NOT USE IT! It does
not meet the safety and testing standards that Canada requires. It is clear that each mobility aid position
must have at a minimum a four-point tie-down system for the mobility aid
(usually wheelchair or stroller) and a lap/shoulder belt (occupant restraint)
for the person in the mobility aid device.
School buses in BC must comply with these standards, so they must have
these systems. This is mandated by
Provincial Law, in the Motor Vehicle Act/Regulations http://www.bclaws.ca/EPLibraries/bclaws_new/document/LOC/freeside/--%20M%20--/Motor%20Vehicle%20Act%20RSBC%201996%20c.%20318/05_Regulations/28_26_58%20Motor%20Vehicle%20Act%20Regulations/26_58_15.xml#section44.8
A taxi that is being
used as a school bus is also legally required to meet these same standards (in
other words, they MUST have a MASOR system that meets CSA Z604/605 standards
installed) and although taxi drivers are exempt from ambulatory passenger seat
belt laws (in general - NOT so when used as a school bus) they are also NOT
exempt from this in the case of a wheelchair-seated passenger - they MUST use
the complete MASOR system (look at Motor Vehicle Regulation section 44.8 (2)).
Some people do not
realize the forces involved in a motor vehicle crash. The standard for the automobile industry
(which has been adopted by the wheelchair industry) for crash testing is 30
MPH/48 KMH. The deceleration forces in
this type of crash (one vehicle going from 50 km to dead stop) is 20G!! That means that your 100 pound child now is
2000 pounds, or one ton!! These are
extremely high forces and the occupant restraint system (lap and shoulder belt)
serve the same function as a vehicle lap/shoulder belt - keep them from being
ejected (from their seat, which in this case is a wheelchair or stroller and
from the vehicle. If it is not done up
properly, securely, and routed on the chair the way best practice dictates,
this safety feature will not work! For
children that are riding school buses that travel at highway speed, the
possible crash forces are even greater.
That is why it is so imperative that the restraint system is used
properly.
For those who are
interested in more documentation about the crash-testing standards, wheelchair
transportation in general, and to look at some excellent crash-testing footage,
go to http://www.rercwts.org/ This is an
excellent site that has an absolute wealth of information and resources on
it. The only caution I have is that this
is a US based site, and although the US is much ahead of Canada in rights and
requirements for persons with disabilities, Canada leads in safety standards,
and there are definitely products and concepts that are considered safe in the
US, but not in Canada.
The other main lack in
safe transportation (and of course this is just my opinion based on 15 years as
a care provider and 10 years of working in the vehicle modification industry)
is that there are few resources easily available to train people in real-world
safe transportation. I know Q'Straint
and Sure Lok (the two restraint system manufacturers that meet Canadian requirements)
do have great training programs. What
they do not address however is things such as the high-end complex seating
systems that have a lot of components to them and make proper occupant
restraint system location very difficult.
They don't really address or inform about the interaction of postural
support (what you show above Barbara) and occupant restraint. Only an Occupational or Physical Therapist
can determine what is necessary for postural support for transport, but there
may be a disconnect or lack of knowledge/understanding on the part of the
person applying the occupant restraint system as to what the postural support
is for, how it functions, and what it should look like done up. Likewise, the person doing up the postural
support may not realize why it is so absolutely vital in many cases to proper
occupant restraint effectiveness.
Sorry for such a long
note, but it's a complex process!
If you are a parent and
have any concerns about how your child is being transported for school or in
any other situation, you absolutely have the right and obligation to question
the care provider, and refuse transport if it is not done properly!!! Your child's safety is absolutely number one!
