Gaseous Extinguishing System Design covers aspects of Gas Suppression System Design.
This training course is for learners conducting design of Gaseous Fire Extinguishing Suppression Systems to gain knowledge of the requirements for conducting these works.
Learners who successfully complete this course are able to demonstrate comptency in and knowledge of Designing of Gaseous Fire Extinguishing and Suppression Systems.
This course assumes the learner can read, write and understand English and has a knowledge of the Installation and Commissioning of Gaseous Fire Extinguishing and Suppression Systems. Learner demonstrate knowledge of and comptency in the current applicable SANS Gaseous Fire Extinguishing and Suppression System Standards.
Designing Gaseous Fire Extinguishing Systems requires particular skills to ensure that the system will be effective when a fire condition is encountered.
This training course is only conducted online. Please forward your enquiries to firstname.lastname@example.org.
