Hydrogen sulfide (H2S) is a flammable and explosive gas, and can also be toxic when inhaled. It’s heavier than air, so it tends to collect in poorly ventilated low-lying areas. Because of its inherent danger, it’s important to respond appropriately if your H2S monitor alerts you to the presence of this gas.

Get out of the Area
If an H2S gas detector is triggered, vacate the area as quickly as possible. If you have safety gear, put it on at this time. Jobs with a higher risk of H2S exposure–such as water treatment plants and oil drilling operations–often have H2S safety gear and are required to teach their employees how to properly use it. To get out of the reach of the gas, get upwind. If you can, move to a higher, unconfined area.

Account for All People
Once you’re safe, check to see if everyone else was able to get out of the area successfully. Hopefully, they all heard the H2S gas monitor alarm and were able to get out in a timely fashion. If you’re on the job, your training should include protocol for where to meet and how to make sure everyone is accounted for. 

Notify the Authorities
After you’ve made sure that everyone is safe, call the local authorities to let them know of the H2S exposure. This will ensure that the site is properly evacuated, as well as nearby homes or businesses that may be affected as well. Also, inform the authorities if you weren’t able to account for everyone: they’ll need to send in rescuers with the appropriate training and gear for an H2S emergency.

Ventilate the Area
The final step to dealing with an H2S emergency is to ventilate the area to let the dangerous gas disperse safely. The authorities will take charge of this process so you won’t be at risk of exposure. You should also find out if there are steps you can take to prevent the problem from happening again.
