description
The largest industrial route to H2S occurs in petroleum refineries. The hydro desulfurization process liberates sulphur from petroleum by the action of hydrogen.
Red Zone (category 0 area) – Risk of fatality.Yellow Zone (category 1 area) – Risk of injury.Green Zone (category 2 area) – Risk of short term nausea, irritation.
H2S Detection Equipment to be installed can control to save your life. Equipment that are used for Detection of H2S, they are mainly of 2 types 1. Fixed Detection Equipment2. Portable Electronic and Chemical Detection Equipment.
Air-purifying respirators (APRs) should not be used where H2S levels are above the 10 ppm Ceiling Limit.
You and your team must:• Be competent in using gas detectors and breathing apparatus.• Be Familiar with all H2S alarms Include H2S hazards in all risk assessments.
A few scenarios should be selected from the overall set, preferably the largest cases of each type of accident. These are the planning base accidents for emergency planning.
Establish and train emergency rescue teams (ERT) hold regular practices. Include resuscitation of H2S victims in first aid training.
