Rule 36 Basics

Rule 36 is a safety rule established by the Texas Railroad Commission. It is designed to protect the general public from the hazards of hydrogen sulfide (H2S) resulting from intentional and accidental releases.

Rule 36 is a progressive rule relative to compliance. The level of compliance required is determined by 100 ppm and 500 ppm ROE.

Rule 36 outlines injection, training, notification, reporting, and analysis provisions and requirements.

Manning Safety Services is fully equipped to assist you with Rule 36 compliance, monitoring, and reporting requirements.
