Latest / Safe As Podcast / E21: Beyond the Hierarchy - Haddon's energy countermeasures (Quickisode)
Transcript
- 0:06William Haddon Junior, have you heard of that name?
- 0:09If not but to use energy based hazard concepts or worked in Rd
- 0:15safety, urbanomics or sports science, the chances are you've
- 0:19directly been influenced by his work.
- 0:21Haddon Junior was a hugely influential US researcher and
- 0:25safety advocate, particularly in Rd transport from the Sixties,
- 0:2870s and 80s. Today is the first of a special
- 0:31episode of say, FAZ. Let's call it a quick asode.
- 0:35It won't make me feel a little weird, but let's roll with it.
- 0:38In quick asodes I aim to capture an interesting tool or concept
- 0:41in an even more frantic and lower quality way than usual.
- 0:45Hadn't established 10 measures for eliminating or mitigating
- 0:49the exchange of hazardous energy.
- 0:51In many ways I think it's superior to the hierarchy of
- 0:53control. Let's apply it to a well known
- 0:56area like fall prevention #1 prevent the hazard from coming
- 1:01into existence. This could be like designing
- 1:03buildings with ground level access for tasks.
- 1:06Use extendable tools or automation so work at hide is
- 1:09not required. Or prefabricate assemblies at
- 1:13ground level before insulation 2.
- 1:16Reduce the amount of hazard that is brought into existence.
- 1:19This could be limited hide exposure by lowering the working
- 1:22platforms. Where feasible, use portable
- 1:24work stands instead of scaffolding where only small
- 1:27elevation is needed and restrict roof access points to only
- 1:31essential personnel. 3 Prevent the release of the hazard that
- 1:35already exists. Install guard rails and barriers
- 1:38around roof hedges and openings. Use tow boards and safety gates
- 1:42on ladders and scaffolds. Secure tools and materials to
- 1:45prevent them from becoming falling objects. 4 Modify the
- 1:49rate or spatial distribution of release of the hazard.
- 1:53So use controlled descent systems or slow moving lifts to
- 1:56prevent sudden drops. Place staging areas further from
- 2:00edges to keep workers away from the fall zone, or install work
- 2:04positioning systems to limit movement into hazardous zones 5.
- 2:09Separate in time or space the hazard from that which is to be
- 2:12protected. So schedule work at heights when
- 2:15fewer people are on site. Below as in reducing the risk of
- 2:18dropped object injuries. Keep unrelated workers out of
- 2:21the fall zones using exclusion zones in signage. 6.
- 2:25Separate the hazard from that which is to be protected by
- 2:28material barrier. So use scaffolding with full
- 2:31enclosures with mesh or netting. Fit skylight covers to prevent
- 2:35fall through fragile roofs. Install safety Nets under
- 2:38elevated web platforms 7. Modify relevant basic qualities
- 2:43of the hazard though use non slip surfaces and platforms to
- 2:46reduce slip likelihood. Reduce platform heights where
- 2:50possible. You know like step stools
- 2:51instead of ladders. Ensure ladders are wide based
- 2:55and have stabilising feet. 8 Make what is to be protected
- 2:58more resistant to damage. A little bit harder when it
- 3:01involves people but maybe require personal fall arrest
- 3:04systems. You know full body harness and
- 3:05lanyard shock absorbing lanyards to reduce impact forces.
- 3:10Train workers in fall arrest self rescue techniques. 9
- 3:14Counter the damage already done by the hazard.
- 3:16Provide immediate rescue plans for the suspended workers.
- 3:20Ensure on site first datas are trained in trauma and
- 3:22suspension, trauma treatment and having emergency response groups
- 3:2610 Stabilise, repair and rehabilitate the object of
- 3:29damage. So offering medical
- 3:32rehabilitation programmes for injured workers and adapting
- 3:35roles to suit partial recovery while maintaining employment.
- 3:39Now, it doesn't perfectly align with all of the known factors of
- 3:42hazard interactions and incidents, your psychosocial
- 3:46factors, and let's not go into mental or psychological energy,
- 3:49please. But it doesn't need to either.
- 3:52It helps provide one structured process for one slice of the
- 3:56hazardous energy pie. Why not give it a go and let me
- 3:59know how you find it compared to or in conjunction with the
- 4:02hierarchy of controls? That's it on this quicker side
- 4:05of safe as. Thanks everyone.
