ES&H employs safety technicians, permit writers, and safety professionals with the certification, qualifications, and experience you need to support your safety program. All of our safety personnel have at least five years of dedicated experience in safety. And most have spent well over fifteen years in the petrochemical industry (about two-thirds are retired plant safety professionals). In addition to their primary duties, they serve as an extra set of eyes in the field and can provide contractors with on-the-spot technical assistance.
