Warning Safety Sign - "H2S Gas Can Cause Metal Fatigue Inspect Equipment For Signs Of Sulfide Stress Cracking"
Corrosive GHS Symbol
"WARNING SIGN" indicates a hazardous situation which, if not avoided, MAY result in death or personal injury.
Post warning signs in areas where equipment may be affected by stress cracking and metal fatigue. This type of release is often not noticed by oil and gas drilling employees until they have been trained to look for it and identify it to supervisors. Metal fatigue, including hydrogen embrittlement or sulfide stress cracking, can result in a release of hydrogen sulfide gas. Possible hazards may occur by getting Injured due to equipment failure. Hydrogen sulfide reacts with metal ions to form metal sulfides, which may be considered the salts of hydrogen sulfide. Some ores are sulfides. Metal sulfides often have a dark color. Lead(II) acetate paper is used to detect hydrogen sulfide because it turns grey in the presence of the gas as lead(II) sulfide is produced. Reacting metal sulfides with strong acid liberates hydrogen sulfide. If gaseous hydrogen sulfide is put into contact with concentrated nitric acid, it explodes.
