Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Discuss the legislative framework applicable to a hazardous process
LO2 Describe the types of process safety hazard that may exist
LO3 Apply standard techniques to identify process hazards
LO4 Propose control measures to reduce process risks
LO5 Assess, using basic techniques, the risk posed by a hazard
LO6 Interpret the safety implications of safety-related documentation and tests.
Pre-requisite learning
Module Recommendations

This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).

Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
