Latest / Safe As Podcast / E46: The Stuff That Kills People and weaknesses in Critical Control Programs
Transcript
- 0:07Do our critical control verification processes operate
- 0:10as intended? Are they actually geared towards
- 0:12the stuff that kills people or well intended but superficial
- 0:17fluff? Let's find out.
- 0:20Good everyone. I'm Ben Hutchinson and This is
- 0:22Safe as a podcast dedicated to the thrifty analysis of safety,
- 0:26risk and performance research. Visit safetyinsights.org for
- 0:31more research. Today I'm covering 2 industry
- 0:35reports, an interim and final report from Left's Read ET al
- 0:402025 titled Building Resilience into Safety Management Systems,
- 0:47Precursors and Controls to Reduce Serious Injuries and
- 0:50Fatalities. SIFTS The research was motivated
- 0:54and funded by a creative sentence for the death of
- 0:56Patrick, a contractor who drowned when his bulldozer fell
- 1:00through ice on a frozen tailings pond at the Suncorp Base mine in
- 1:042021. The overarching objective of
- 1:07this creative sentencing research is to to understand the
- 1:10hazards that result in SIFTS, serious incidents and fatalities
- 1:15within mining and any causal and contributing factors and the
- 1:19most effective controls to prevent fatalities.
- 1:22Another goal is to ensure that there are layers for protection
- 1:26so that work fails safely rather than failing lucky or worse,
- 1:31failing unlucky or unsafely. The project engaged in three
- 1:36complementary research activities.
- 1:38There were workshops, there was data analysis of critical
- 1:42control assurance verifications, and it was matched against SIF
- 1:46events or the potential or actual SIF events.
- 1:49And then there were surveys and interviews of the hazard
- 1:51identification and human and organisational performance
- 1:54factors with people. So just upfront, some
- 1:57definitions. So I've mentioned SIF before,
- 1:59I'll use that a bit more. Serious incidents and
- 2:02fatalities. These reports also adopt the
- 2:05Icmm's definition. So controlled by that source is
- 2:10an act, object engineered or system, a combination of act or
- 2:14object intended to prevent or mitigate an unwanted event.
- 2:18Also, I'll be talking about critical controls.
- 2:21So critical control is a control that's crucial to prevent the
- 2:24event or mitigating the consequences of the event.
- 2:28The absence or failure of a critical control would
- 2:30significantly increase the risk despite the existence of other
- 2:34controls. Now, I can't do these two
- 2:37reports just as that. There's just too much detailed
- 2:39findings. So I'll just cover a few key
- 2:41points that I found interesting. So what did they find?
- 2:45So some of the insights from the workshops around building
- 2:48resilience. So first a focus on high energy
- 2:51hazards or what they call stuff that kills you.
- 2:54The workshops with over 200 subject matter experts, they
- 2:58repurpose some bow tie diagrams that they said really helped
- 3:01workers see the high energy hazards and sort of the
- 3:04contributing causal factors and the layered system of controls.
- 3:09So I've skipped a lot of these findings, but the report
- 3:12strongly recommends that companies should consider when
- 3:14they're identifying their stuff that kills you and developing
- 3:18layer controls for these hazards and ensure that these controls
- 3:21are in place and functional. Nothing new there.
- 3:24They said that to use these sorts of bow tie visualisations
- 3:28really help show the hazards and the layers of control.
- 3:31It might just be bow ties or it could be critical task
- 3:34infographics, start work, check diagrams and whatever.
- 3:37But they talk about sharing these visualisations with
- 3:40workers so they can better see, monitor and manage their
- 3:43workplace hazards. And importantly, as the work is
- 3:47really done, you know, work is done versus work is planned or
- 3:50work is imagined. They argue that visualisations
- 3:53also trigger curiosity and curiosity eliminates fear.
- 3:58So these tools are now being used for pre task planning and
- 4:01training and critical control assurance.
- 4:03Some of the other findings is that checking the efficacy of
- 4:07critical controls by comparing or contrasting against our
- 4:10actual incidents. So enhancing the critical
- 4:12control assurance questions or processes, evaluating work and
- 4:16perceptions of risk versus the hazards they're exposed to and
- 4:19whether there's any fear of repercussions that can suppress
- 4:22hazard reporting or overconfidence that could lead
- 4:25to perhaps shortcutting safeguards and the
- 4:28verifications. They also unpack some of their
- 4:31psychological safety discussions.
- 4:33So these workshops were aimed to create a psychologically safe
- 4:36space to discuss human dynamics, leadership, organisational
- 4:40factors potentially related to the SIF incidents.
- 4:43Psychological safety is defined as a belief that one will not be
- 4:47punished or humiliated for speaking out with ideas,
- 4:50questions, concerns or mistakes and that the team is safe for
- 4:54interpersonal risk taking. Interestingly, on this point,
- 4:58when participants were asked to rate the level of psychological
- 5:01safety that they perceived at a recent site visit, the average
- 5:05score was just 3.8 out of seven. So less than a 50% score, which
- 5:10is quite concerning that most people didn't perceive there to
- 5:13be a high level of psychological safety.
- 5:15It wasn't a safe environment for interpersonal risk taking.
- 5:19Next, we'll move into things that I found a bit more
- 5:21interesting around the the data analytical side.
- 5:24You know, when they compared the critical control verification
- 5:27activities versus the actual reported SIF events, like the
- 5:31potential or actual SIF events. And they leveraged machine
- 5:34learning and natural language processing across 5 mining
- 5:37operations. Giving a bit of background, they
- 5:40say Sifs have complex precursors that are not easily visible in
- 5:44companies, physical environments or in their reports or even what
- 5:48workers say. Hence many SIFT recursors are
- 5:51only visible watching the work is done and how it differs from
- 5:55work is intended. And this applies even to routine
- 5:58work where they say controls may be insufficient, bypassed or non
- 6:02functional. They believe that bow ties are
- 6:05useful for visualising the presence of safety capacities.
- 6:09Bow ties demonstrate that safety is the presence of layered
- 6:13controls rather than an absence of serious consequences.
- 6:17Nicely, they say that bow ties make the invisible visible and
- 6:20the unspeakable discussable. With more resilient capacities,
- 6:24they argue, the system is more likely to fail safe than fail
- 6:27lucky. So what did they find with these
- 6:30gaps in the critical Control assurance versus the actual
- 6:33events? In mining and tailings
- 6:35operations, SIP incidents related to working with or near
- 6:38energised equipment constitute 60% of the incidents.
- 6:43But critically, just 8% of the critical control assurance
- 6:47activities focused on these same scenarios.
- 6:50Also, exposure to toxic materials or hazardous
- 6:53atmospheres constitute 5% of the incidents.
- 6:57Yet the critical control assurance activities focused on
- 7:00just .1% of these hazards. For production and processing,
- 7:04working with or near energised equipment and toxic exposure
- 7:08account for 25, around 25% of the SIF incidents.
- 7:12Yet critical control assurance activities only focused on
- 7:15between 1 and .13% of the hazards.
- 7:19And another one. I've skipped a lot of these, but
- 7:22exploration and drilling dropped objects accounted for the
- 7:25highest number of CIF incidents, 83%, but accounted for just 38%
- 7:31of the control assurance activities.
- 7:33So these findings help identify the potential for enhancements
- 7:36to the quality and attention of critical control assurance.
- 7:39It suggests that much of the stuff we're actually observing
- 7:42during the critical control assurance activities isn't
- 7:45properly calibrated. The things that's actually
- 7:48hurting people or potentially will hurt people.
- 7:51They also unpack some insights from a human and organisational
- 7:54performance perspective. So talk how the surveys revealed
- 7:58that the participants, the participants attitudes generally
- 8:01have the strongest relationships with the proxy safety variables
- 8:04that were measured in this in these reports, which they say
- 8:07emphasise the importance of social psychological factors in
- 8:10shaping safety. It's not just about physical
- 8:13controls, it's about people. People create safety, they
- 8:17create safety capacities. They also found that one of the
- 8:20strongest predictors of safety perceptions accrues.
- 8:24You have positive safety attitudes.
- 8:26For instance, my crew places a great deal of emphasis on safety
- 8:31and beliefs that they can conduct the work safely, like a
- 8:33collective efficacy. So in other words, safety,
- 8:36climate and precursors around climate where the leaders are
- 8:41seen to actually care about safety, whether the environment
- 8:44is conducive to people to be able to work safely, were
- 8:47important. They also covered some of the
- 8:49reasons for the hazards not being identified or reported.
- 8:52Probably nothing really new here for most people, but some of the
- 8:55key areas. The first was worker
- 8:58inexperience. So these sorts of demographics
- 9:02may not have enough knowledge or experience in their role to
- 9:04recognise features of their environment as hazards.
- 9:08The safe career implications was tied up, so participants noted
- 9:11that people may not report hazards due to perceived fear
- 9:14that reporting may have a negative consequence for their
- 9:17current employment or career trajectory.
- 9:20The perception of fear of negative consequences appears to
- 9:23be a strong driving force for why some people might hesitate
- 9:27to report a hazard. There's perhaps a normalisation
- 9:30of some of the hazardous work. So a perception that the very
- 9:33nature of mining and oil and gas work is dangerous and therefore
- 9:37it's just normal or expected to encounter hazards need frequent
- 9:41exposure to these sort of embedded hazards.
- 9:44They also contribute to a desensitisation where the hazard
- 9:47is accepted as part of normal work and therefore employees may
- 9:51assume reporting is unnecessary. And another factor under
- 9:55recognition of hazards is a discrepancy between general fear
- 9:59and specific hazards. So while 15% of respondents
- 10:03feared career repercussions and 11% feared social repercussions
- 10:07if they identified and tried to mitigate a hazard, only around
- 10:12somewhere between 3 to 17% actually feared specific
- 10:16hazards. So most of the fears that
- 10:19resulted from hazards relate to people fearing social
- 10:22repercussions, you know, getting socially outcasted by their crew
- 10:25members or getting penalised by management for reporting things
- 10:29rather than actually having a real sensitivity to the harm
- 10:33that can result from that hazard.
- 10:34So overall, trying to wrap all this together again, I've
- 10:38skipped a lot, but they draw on Conklin's hot principles.
- 10:42So accepting that people make mistakes, accepting that blame
- 10:46won't necessarily fix things, accepting that context tries
- 10:50behaviour. Learning is vital and how we
- 10:53respond to incidents and hazards and people really matters.
- 10:58Also explain the importance that our system should increase the
- 11:01chances of failing safely rather than failing lucky or failing
- 11:06unsafely or unlucky. And specifically for our sift
- 11:10hazards and interactions, they offer some preliminary
- 11:13suggestions. Query in the paper.
- 11:16Create a hazard and inventory of work is done in all mine
- 11:19operations. So how does work actually get
- 11:21done? Describe it, learn about it,
- 11:24detail it Identify or develop indicators for SIFT precursors,
- 11:29controls and insurance and audits.
- 11:32Make sure we're actually inspecting and learning and
- 11:35monitoring the things that really matter Determine which
- 11:38activities are most likely to be completed by contractors and the
- 11:41hazardous work and interactions. Examine how indicators and
- 11:45controls and control and barrier assurance vary across owners and
- 11:49operators, contractors and subcontractors.
- 11:52Not mentioned here, but we know that the principal contractors
- 11:56and the clients often shift the risk down their contracting
- 11:59chain. So they often transfer the more
- 12:03severe risks to contractors that probably had the least resources
- 12:07to properly eliminate those sorts of hazard exposures.
- 12:10They also mentioned in the report surveying prevailing
- 12:14safety climates and beliefs and norms with the owners and
- 12:17contractors, et cetera. Build systems level, multi
- 12:21layered, effective and insured controls at different levels.
