Confined Space Operations

When your life is on the line, you need a Sentry watching over you. Our teams provide training, supervision, and rescue services for the most critical confined space entry tasks for tank batteries, production sites, industrial plant applications and more.

H2S/ LEL Safety Services and Rentals

This is the service we were founded on, and we are the best in the business.  Sentry has everything you need to meet the requirements for Texas State Rule 32.  We have both Scott and Draeger systems available for forced supplied air work units, SCBAs and escape packs packaged in trailers with signage, windsocks, and more.  When things get really dangerous, we are there for you with dedicated and trained H2S supervisors to ensure the safety of your entire work location.
