What are the Considerations for Instrument Installation in Hazardous Environments (Part II)?

In the preceding article, the subject of targeted measures for the installation of instruments in explosive and high temperature and pressure conditions was introduced. The article will further explore the measures for toxic and oxygen-rich medium.

Highly Toxic Medium

Preventing leakage is the core of safety in such environments:

Pipeline and Valve: Impulse lines, fittings and valves must be made of high-quality material whose processing and welding strictly comply with standards. Strength and tightness tests must be completed to ensure zero leakage.

Safety Protection Systems: The construction area must be equipped with effective ventilation and detoxification facilities to ensure rapid removal of toxic gases in the event of a leak. Sufficient personal protective equipment, such as gas masks and protective clothing should be provided for personnel.

Monitoring and Alarm: Toxic gas or substance detection and alarm instruments should be equipped on-site with safe thresholds set. If concentrations exceed limits, alarms should be triggered at once to cease operation and evacuate personnel.

Oxygen-rich Medium

Oxygen has strong combustion-supporting properties. In high-concentration, high-pressure oxygen environment, even minor oil contamination can lead to combustion or even severe explosion.

Strict Oil Prohibition: All pipelines, valves, instruments and components in contact with oxygen must undergo thorough oil-free treatment before installation to ensure no oil residue remains.

Clean Operation: Oil-free tools must be used during installation. Operators should wear clean gloves, and any introduction of oil contamination is strictly prohibited to prevent secondary oil pollution.

Instrument installation in hazardous environments is a systematic engineering task that integrates technical specifications and safety management. It requires selection of products with appropriate protection ratings and implementation of risk control throughout the entire process.
