is applied. |
| Strand |
A component of wire rope consisting of wires wound
spirally together, which is then helically laid around a core to form
the rope. |
| Strain (muscular) |
A strain constitutes those changes indicative of homeostatic
disturbance that appear when the stress responses become in sufficient
to cope with the imposed load. While stress responses continue to
be evoked, they are accompanied by a disturbance or dislocation of
a steady or equilibrium state e.g., increase in muscle strain beyond
ability to maintain a steady state aerobic metabolism is indicated
by an increase in lactic acid output. |
| Stress |
The load transmitted per unit area of cross-section,
usually expressed in MPa (megapascals). |
| Stress |
An interaction between the person and their (work)
environment and is the awareness of not being able to cope with the
demands of one's environment, when this realisation is of concern
to the person, in that both are associated with a negative emotional
response. |
| Stress management |
Used here to refer to three ways of dealing with workplace
hazards that lead to stress and fatigue: eliminate, isolate and minimise.
The HSE Act requires that these strategies be considered, in that
order of priority. Examples of each are:
- Eliminate: replacing level crossings with bridges
so that it is impossible for trains and cars to collide.
- Isolate: confine the work to special purpose areas;
confine the performance of the work to specially trained people or
teams.
- Minimise: reduce the time of exposure to the stressor,
provide prompt performance feedback and training if necessary, select
the right people for the work and provide support. |
| Stress prevention |
- Primary Prevention: creating a healthy place of
work and controlling stressors so that the work is interesting, rewarding
and paced within the person's capabilities (i.e. elimination of the
hazard).
- Secondary Prevention: improving the fit between the person and the
job by selection, on-the-job training, performance feedback and monitoring
of problems (i.e. isolation of the hazard to adequately trained and
equipped personnel).
- Tertiary Prevention: helping the person suffering from stress (also
called minimisation or stress management). |
