Attachment A. TCT Bullet Trap Safety, Operation, and Maintenance.pdf

This is an Operation & Maintenance Manual for the TCT4D (Total Containment Trap 4D), a steel bullet trap system manufactured by Action Target, Revision 1.0, dated April 21, 2020.

The TCT4D is a projectile containment system designed for indoor and outdoor firing ranges that uses hardened steel deflector plates and a sealed, enclosed deceleration chamber to capture bullets while significantly reducing lead particulate emissions compared to traditional open-frame traps. The system features multiple impact plates oriented at increasing angles to break up and decelerate bullets, with fragments collecting in containment canisters at the chamber base for disposal or recycling. The manual covers comprehensive operational and maintenance requirements including regular lead removal from collection canisters, mineral oil application to prevent lead buildup and chamber blockages (using technical grade 70T white mineral oil applied every 7-10 days in high-use scenarios), HEPA vacuum cleaning procedures, and monthly to annual inspections of the deceleration chamber. Critical maintenance includes checking minimum clearances between mouth plates (minimum 1/2 inch), visual inspections for obstructions or lead clogs using flashlights, inspection of the chamber rear shell for ruptures or bulging that could indicate ammunition non-compliance or excessive wear, and professional thorough inspections every two years by approved Action Target technicians. The manual emphasizes mandatory personal protective equipment during maintenance (Tyvek suit, full-face respirator, metatarsal steel-toed shoes, gloves, eye and hearing protection), proper lifting techniques for heavy components, and prohibits oiling the steel plates as it complicates lead recycling and damages dust collection unit filters. Safety considerations note that while the TCT4D virtually eliminates bullet splatter toward the shooter, some fragmentation remains unpredictable, and the system is a primary containment device only with secondary containment recommended for outdoor installations to prevent environmental lead contamination.
