7. Safe operation of major hazard installations

7.1. General

7.1.1. The safe operation of a major hazard installation should be the

responsibility of works management.

7.1.2. Works management should ensure that the major hazard installation is

always operated within the limits of intended design.

7.1.3. Works management should take account of all hazards identified in the

hazard analysis together with possible technical and organisational control

measures.

7.1.4. Measures used to control hazards should include:

– component design;

– manufacture of components;

– assembly of the installation;

– process control;

– safety systems;

– monitoring;

– management of change;

– inspection, maintenance and repair;

– training of workers;

– supervision;

– control of contract work.

7.2. Component design

7.2.1. Each component of a major hazard installation, such as reaction

vessels, storage tanks, pumps, blowers and so on, should be designed to withstand

all specified operating conditions.

7.2.2. Works management should ensure that the following aspects are taken

into consideration when designing a safety-relevant component:

(a) static forces;

(b) dynamic forces;

(c) internal and external pressure;

(d) corrosion;

(e) stresses due to large differences in temperature;

(f) loads due to external impacts (wind, snow, earthquakes, settlement);
