Government and military sites like training towers, aircraft hangars, vehicle depots, and maintenance shelters each come with unique fall protection challenges. These environments often involve elevated work areas, heavy machinery, and secure zones with restricted access.
In these settings, fall protection systems must do more than prevent injuries—they also need to protect the integrity of surveillance systems, restricted areas, and sensitive infrastructure. That’s why Tritech designs engineered fall protection systems that are security-conscious and fully compliant with OSHA and ANSI standards.
We also understand the importance of working within high-security environments. All of our technicians undergo rigorous background checks and are trained to navigate strict access and screening protocols required at government and military sites. We deliver turnkey fall protection solutions that keep your personnel safe and your operations secure without disrupting mission-critical activities.

Key Questions
What is the OSHA 4 foot rule?
The OSHA 4-foot rule is the general industry trigger under 29 CFR 1910.28(b)(1): workers exposed to a fall of 4 feet or more to a lower level must be protected. Aircraft maintenance in a hangar is general industry work, so the rule covers technicians on wings, fuselage crowns, tail sections, and maintenance docks, where working heights run past 4 feet on even small airframes.
What are the 4 types of fall protection?
The four types are fall elimination, passive fall prevention (guardrails and covers), fall arrest (harness-and-anchor systems), and administrative controls. Hangar work is a case where the preferred passive options run out fast: a guardrail cannot follow a curved fuselage or a wing edge, so overhead fall arrest systems that track the technician across the aircraft carry most of the protection. Tritech engineers, fabricates, and installs those overhead systems and recertifies them on an ongoing schedule.
What is the new OSHA standard for fall protection?
The current standard is the 2016 update to 29 CFR 1910 Subpart D (Walking-Working Surfaces), effective January 2017. It aligned general industry with construction, set the 4-foot trigger that governs hangar work, and phased out cages on fixed ladders in favor of ladder safety or personal fall arrest systems on ladders over 24 feet, with cages fully phased out by November 18, 2036. That ladder provision applies to the roof-access ladders on most hangar buildings.
