Can matters be improved?
An identification of risk control options to reduce the identified risks.

A determination of the benefit and effectiveness of each risk control option.

What action should be taken?
An identification of the appropriate course of action to deliver a safe activity based on
the hazards, their associated risks and the effectiveness of alternative risk control
options.

In summary, the risk assessment should ensure that protective and precautionary
measures are taken which will reduce the risks associated with a task to a level that is
considered to be as low as reasonably practicable (ALARP).

9.3 Permit to Work Systems
ึ

9.3.1 General
While companies will develop their own procedures for managing all aspects of
operations and tasks undertaken, many operators choose to incorporate a
Permit to Work system into their SMS in order to manage hazardous tasks.
A Permit to Work system is a formal written system that is used to control
certain types of work. It delivers a risk based approach to safety management
and requires personnel to undertake and record risk assessments in the
development of a safe system of work.

Guidance for establishing a Permit to Work system is contained in a number of
publications issued by industry organisations and national safety bodies.
The Permit to Work system may include one or more of the following

documents to control hazardous activities:

A maintenance procedure.

A local procedure.
An operational procedure.
A check-list.

A permit.

The measures to be employed when carrying out a particular task are
determined by a risk assessment and recorded in the Permit to Work.
