Prevention and action

Humidification in mining sector

V. Pueyo (R Wey Mendes)



Point of view & Summary

• Consider prevention as a project,

• An opportunity and a way for development of activity.

• What about diagnosis (nature, status, backgrounds) ?

• How to go to the transformation ?

• eference ! research in mining sector (R. Wey Mendes)



What about diagnosis -The context

• Health and safety problems in the mining companies

in "spirito #anto,

• "pidemiological studies (dust & pneumoccocioses),

• $%&'! creation of a regulatory framewor( (NR22),

• )o provide humidification throughout the e*traction

process and the mineral processing,• $%%'! + dust (working group),

• ++&! after repressive interventions, deployment.



The standard : characteristics

• )he standard ! a result of epidemiological models (risk

actors!diseases, e"posure),

• -niversal and generic dimensions (#s speciicities &

particu$ar conte"t)

• )he standard

• indicates what is right.

• advances a non/negotiable objective

• an ethic of conviction.

• 0121)his is not the efficiency premium that is to say

the material triumph of value, but its respect.0 (%ottois,

'')



Consequences for action

• A standard product

• an abstract value, detached from wor(,

• no confrontation with the real, its particularities and its history,

• no indication of the means and technical resources to implement,

• unthought innovation.

• 3olitical imposed and normative action,• #o, what about action ? Actors ? 4ialogues and objects, and in which perspective ?

• A principle is indisputable.

A diagnosis withouth diagnosis

• In the field of prevention, standards are essential.

• 9ut if diagnosis is

• identifying the problem to be treated,• setting visibility,

• setting lin( resources,

• the starting point for project and transformation,

• then, the standard can:t play this role.• #tandards originate within the authority, conventions

of coordination and settings, technical standards.



!ow to go to action Summary

• Introduction of humidication : examinedisorders to understand and to act,

• Reconstruction and developement underconditions: workers are not passive,

• Systemic appropriation : benets andconditions.



"isorders

• he real resists,

• ;rder! an intelligible and coherent relation, satisfying

the re8uirements of the mind, which can beestablished between the different elements of the

system,

• Activity is integrative

• 4isorders! witness of inconsistencies, contradictionsand impossibilities.

• An e*ample in e*traction.

#eyond disorders$ %ossibe deveo%ment

• An opportunity to capture what employees tried to put

in place to produce, and better, to do it efficiently.

• Appropriation to describe t*e dynamics in t*e

encounter between t*e standardi+ed, w*ic* is

a$ready crysta$$i+ed in a de#ice or in a new process,

and t*e content and orm o action at work, designedto account or t*e oint de#e$opment o t*e de#ice and

its use - (eguin , 2//0)



A%%ro%riation

$ A techni8ue to be accepted in a new host site must find anchor

points in a cultural, cognitive, or social environment, pre/

e*isting, and which can be set in motion by the technical object,

$ Appropriation covers several possible aspects !

the development of ways of doing and thin(ing @ the evolution

and differentiation of the artifact introduced,

;n the long term, professional genesis concerning developmentof resources for action by wor(ers can be deployed

>development of instruments but also development of

professional s(ills, competencies and conceptuali=ations.



An exam%e : cutting granite surface

• ew cutting machine @ stylus

• )he stylus to engrave a line that would remain visible despite

the water

• "ngraved lines in the stone now guided the cuts firstly made in

using only a visual guide.

• )hese evolutions re8uired operators to learn new s(ills that

were more difficult than had initially been envisaged.

• A temporary acceptance concerning reduction in 8uality.• A speciali=ed production unit, where more e*perienced

operators could underta(e the more comple* and valuable cuts.



Systemic a%%ro%riation

• )he constraints e*perienced by operators became

decision variables in defining companies: technical

and organi=ational options.• )he appropriation of humidification is only possible

when the constraints that it generates and its

resultant resources are ta(en into consideration

within the conte*t of the overall production system

(Mendes & a$. 2/1).

• )he company ac8uires ability to e*periment.



Some ' essons (

• 3revention as a project vs one more overlay.

• #ystemic appropriation to give a new coherence and

sense to a system that has been pushed,incorporating elements related to the realities of wor(

and to challenges of company,

• Consider realities of the wor( activity,

• An arrangement revealed when it is manhandled,• 4ialogues between employees, engineers and

technicians, objects

• eed and opportunity vs duty.



"iscussion

• 4efine a diagnosis, point of departure for a project of

prevention,

• 3lace of standards in tension with specificities, realities

and local issues in project,

• Wor( analysis and systemic approach to understand

what ma(es order, disorder, and meaning, to allow

developments and transformations articulated with

industrial perspectives,

• A revisited project ma(ing tension between logos >normsbut not only and pra*is, not only concerning moral

actors.
