Recording of SSW provides detailed information on the steps to taken when carrying out
activities where the risk cannot be physically eliminated or activities with lengthy procedures
such as carrying out break down maintenance for the drilling machine. SSoW can be
accompanied with a check list to ensure that all steps are followed correctly before starting the
operations.

Written records can be a document used for audit, required for legal reasons for the employer at
the time of carrying out accident investigation.

Technical, procedural and Behavioural Controls

In order to deal with the hazard effectively, we will need to use all three forms of control, to a
greater or lesser degree for example, the use of an ear plugs for the control of a hazard of noise
from machinery.

Technical controls

Strategies which can prevent hazards, mitigate its severity, or minimise the likelihood, for
example gas/fire detection system, early warning radar system, fencing and machinery guards,
emergency stop buttons.

Procedural Controls

Procedures to carry out the task to manage the hazard. They will specify the task involved, the
sequence in which the task is carried out with safety actions in place. Procedures often, relate to
the application of technical controls correctly during operations, for example standard operating
procedures, procedures to deal with emergency, maintenance procedures etc.

Behavioural Controls

The behaviour of the individual workers to manage work related hazard. This is considered
through positive behaviour of the worker towards health and safety, for example using guards
while operating machinery, using necessary personal protective equipment required to carry out
the task, monitoring the work by the supervisor, reporting near misses and accidents.

Technical control does not rely on human intervention, whereas behavioural controls depend on
personal behaviour.

Developing Safe system of Work

Task analysis specifically used for critical jobs to identify the potential hazards before the work
starts. The job is broken down into steps and then identifying associated hazards in each step,
followed by hazard identification, hazard control and safe working methods shall be established
to deal with critical jobs.
