Toxic gas monitoring system

Thus, a combination of single point and multi-point gas detectors integrated into a central toxic gas monitoring system might be required to effectively and efficiently protect a facility and its occupants. 

Most toxic gas monitoring systems integrate permanently installed gas detectors in fixed locations throughout a facility. Portable gas detectors, based on several of the technologies found in the analysis functional... 

One fact is for certain both gas detectors and toxic gas monitoring systems must continue to improve to keep pace with future revisions and additions to national, state, and local fire and building codes and modifications to environment, health, and safety regulations for effective and affordable monitoring and protection of personnel, environment, and facilities. 

Most industrial hygiene air monitors in the semiconductor industry are used for flammable and toxic gas leak detection (see Ch. 11, Toxic Gas Monitoring). However, some facilities are also using continuous monitoring systems to ... 

Today, numerous alarm and monitoring systems are required by codes. These include fire alarm, smoke detection, sprinkler system supervision, emergency (spill) alarm, and continuous toxic gas monitoring and detection systems.

Figure 1 shows the overall framework of the consequence analysis and prediction about hazardous material releases in the city. The result of this study may help improving the confidence of residents living next to chlorine storage facilities by supplying an improved emergency respond plan and monitoring system for various toxic gas releases. 

Combustible and toxic gas sensors and monitoring systems are available for a wide variety of gases. Different sensors and sensor systems have advantages in different applications. Data for six important gases arc collected in Thble 19-1. Information from N.O.Korolkoffs review [1] and a collection of information available from the Government of British Columbia, Canada [2-6] are extensively quoted in this article without further referencing.

Another type of monitor is a field mounted hazardous or toxic gas detection device. Such permanent gas detection systems (see Figure 11-7) protects personnel and equipment finm virtually any toxic or combustible gases through audible and visual alarms in the field and/ or on a control board. Permanent gas detection systems consist of a combination of transmitters, intelligent sensors, controllers, and accessories. These types of monitors are used to ... 

It is very important to be aware that the toxicity of ozone applies to humans as well as fish. Breathing in ozone gas will injure the lungs and a high concentration is directly toxic. An alarm system that monitors the ozone concentration in the air should therefore be used, preferably with an automatic close down mechanism on the ozone generator.

As mentioned earlier, the most commonly employed alkylene oxides for producing block nonionic surfactants are the very reactive three-membered cyclic ethers such as EO and PO. Particularly, EO is highly flammable, explosive in some condition, and also toxic and an irritant for skin and eyes. For these reasons, the reactor employed in the synthesis, described earlier, must be equipped with sophisticated safety devices, process monitoring systems, and distributed control systems (DCS) to keep the reaction in safety condition and avoid gas-phase decomposition and the so-called runaway...
