OTHER SAFETY TIPS FOR WORKING IN H2S-PRONE AREAS
• Never work alone in these areas. Use a buddy system. As part of the buddy system, you should always know
where your buddy is and be mindful of his or her safety.
• Hydrogen sulfide is flammable with a flashpoint of just 500 degrees Fahrenheit. Do not smoke in any hydrogen
sulfide area and do not perform any type of welding or cutting operations without first controlling the hazards and
obtaining a hot work permit.
• Maintain an awareness of wind direction and work upwind of potential hydrogen sulfide sources whenever
possible.
• Some facilities use a color-coded system of warnings so workers approaching a potential hydrogen sulfide area
will have knowledge of the current conditions. If your facility uses such a system, make sure you understand the
meaning of each color-coded signal
