Stationary gas monitoring systems: Consequence from responsibility
In many industrial branches toxic, combustible gases and vapours or oxygen deficiency affect people´s health and lifes and cause resultant costs for production and plant. There are appropriate regulations in most countries which give clear hints for the handling of dangerous gases. It is always the owner who is made responsible for all damages. Supervisory authorities inspect and may close plants and production areas if there is a lack in safety. Even smallest amounts of gas may cause dangerous situations. Only a continuosly monitoring fixed gas warning system ensures the required "safety around the clock" without the need od additional measurements taken by your staff.
