The Industrial Safety Systems and Their Types
Industrial automation has minimized the human interaction with the machines but has not completely eliminated it. Industrial safety systems are introduced to protect the human who work in hazardous plants. Some examples of these are oil and gas, chemical and nuclear plants. The industrial safety systems not only protect the humans but also protect the environment and the plant itself from the chemical reactions.
These systems do not control any process but in fact come into play when it is not possible to control a process through normal means. They are rather installed as a protective measure and are quickly becoming the need of every working environment. There are various types of safety systems in place and their use depends on the type of industry they are used in. Here is a look at some of them.
Process Control Systems (PCS)
They are installed for the monitoring of the manufacturing environment and they control the manufacturing process electronically. A laser diode is used for the detection of liquid or gas present in the environment. If the gas or liquid is detected then their particular frequency signature is converted to a digital signal and the processor identifies the signal received.
Safety Shut-down Systems (SSS)
These systems are particularly helpful in the state of emergency as they automatically shut-down a system to a safe state whenever they sense a danger. They can be connected to the fir and gas systems to achieve securer working environment.
Fire and Gas Systems (FGS)
These systems are highly sensitive and intelligent. They sense the inflammable gas, material or liquid spill at an early stage. They also detect the fire within the working environment and give audible and visual signals of the threat detected. These systems can be activated automatically or manually.
There are other systems like Pressure Safety Valves (PSV) and Emergency Shutdown Systems (ESS) that are widely used in the manufacturing industry.
