2019 INFIRES SEMINAR

Automatic Sprinkler Inspection Bureau (ASIB)

The final presentation of the day was by Natasha Goring,
Managing Director of the Automatic Sprinkler Inspection
Bureau (ASIB).

She explained that the National Building Regulations do
not purport, and were never intended to be, a handbook on
good building practice. They set out, in the simplest and
shortest way possible, requirements to ensure that a building
will be designed and built in such a way that persons may
live and work in a healthy and safe environment.

Therefore, the fact that a building complies with the
National Building Regulations will not automatically indicate
that it is a desirable building.

“I feel that we should be looking at what is correct and
not necessarily what is just in line with the building
regulations,” Goring said. “Where sprinklers are required in
terms of the building regulations, it doesn’t necessarily mean
that’s the only place that we should have them.

“We are about to start a debate as to whether or not fire
protection, not just sprinklers, is ethically required. Should
we ethically protect all buildings, or are we looking simply at
cutting costs and taking money?”

Goring continued: “Anyone who is a consultant will know
that frequently you are competing against other consultants
not for minimum protection, but how much you’re willing to
sign off and get away with. It’s a fact. If you’re an insurer, it’s
a matter of who will take the lowest risk. Who is willing to
gamble on it?”

She referred to a recent fire in Orange Grove,
Johannesburg, which had resulted in an insurance claim of
R550-million. Prior to that, the broker had gleefully noted:
“We have saved R5-million by not putting in a sprinkler
system”.

“I bet he’s feeling rather stupid right now,” Goring said. “I
hope the R5-million is worth the R550-million claim!”

She discussed when a sprinkler system is required in
terms of building regulations. Then delved into what should
happen in terms of good minimum protection – which is
ultimately what everyone in the industry is looking for when
it comes to sprinkler systems.

The 2019 InFIReS Seminar concluded with a ‘thank you’
from FPASA Managing Director, Renay Sewpersad, to all
those who participated and helped to make it an important
event on the annual fire protection industry calendar.

Sponsorships make

the seminar possible

The 2019 InFIReS Seminar was made possible by the generous participation of two high-profile sponsors from the
industry: SafeQuip Quality Fire Solutions and BSI South Africa.

Safequip’s presentation was kicked off by Managing Director Pierre Malherbe, who outlined the company’s history and
its ethos of providing a comprehensive range of top-quality products and ensuring that stock is available at all times.

Rudi Vautier, Sales Manager for Europe and Africa, discussed a selection of Safequip’s innovative equipment and
products – specifically the UMC (Universal Manifold Check) valve and the RCW water control valve.

Renowned standards through BSI

Ronel Liebenberg, Product Certification Manager for BSI South Africa, introduced BSI and its background. She explained
that it is renowned as the UK government’s national standards body. It represents UK interests at the International
Organization for Standardization (ISO) and others.

Its role is to help improve the quality and safety of products, services and systems by enabling the creation of
standards and encouraging their use. BSI publishes over 2 700 standards annually. In South Africa, it partners with
organisations to ensure quality, safety and trust through independent third party certification that is robust, trusted and
consistent.

FPASA thanks both SafeQuip Quality Fire Solutions and BSI for their generous assistance in making the 2019 InFIReS
Seminar possible.

46 Fire Protection • June 2019 The Associated Press (AP) reported that Caryn Pfeifer,
whose husband, firefighter Ray Pfeifer, was an advocate for
responders before he died of cancer in 2017, called the
memorial glade "a beautiful place for our heroes".

Pfeifer said that after the 2001 terrorist attacks, her
husband "spent the next nine months searching and digging
at ground zero without being asked, without being told, and
without thinking about the consequences. But there were
consequences. There was illness and pain and death – and
for Ray that meant his guys and their families were in
trouble."

Freyda Markow, who volunteered at the Trade Centre site
with the Salvation Army and the Red Cross, wore photos
around her neck of the firefighters who died years after
responding to the attacks. "For them 9/11 was never over,"
Markow said. "It'll never be over."

Thousands of rescue and recovery workers and many city
residents were exposed to the clouds of thick dust released
when the twin towers collapsed.

Many spent weeks working without proper respiratory
protection as fires continued to burn and later developed
respiratory and digestive-system ailments potentially linked
to inhaled and swallowed dust. Over the years, more have
been diagnosed with other illnesses including cancer, the AP
report said.

Researchers continue to study whether there is a link
between those illnesses and toxins present during the clean-
up. One study found that overall mortality rates among
rescue and recovery workers have not been elevated. But
researchers have raised concerns about an unusual number
of suicides among first responders and more deaths than
expected from brain cancers and non-Hodgkin's lymphoma.
