Why H₂S cases need a specialist

H₂S is a deadly, fast-acting gas found around drilling, completions, and production. OSHA caps general-industry exposure at a 20 ppm ceiling (with a one-time 50 ppm peak for up to 10 minutes), and NIOSH classifies 100 ppm as “immediately dangerous to life and health.” Olfactory fatigue means workers can’t rely on smell. (OSHACDC)

In Texas, operators must follow Railroad Commission Statewide Rule 36—including written H₂S contingency or reaction plans—and document compliance (Form H-9). API’s recommended practices (RP-49 and RP-55) also set industry standards for drilling and production in H₂S areas. (Railroad Commission of TexasAPI)
