CBRN EQUIPMENT MAINTENANCE STANDARD OPERATING PROCEDURE

176th Engineer Brigade (TXARNG)

Administrative Data

1. PURPOSE

This SOP establishes brigade minimum standards for maintenance of chemical, biological, radiological, and nuclear (CBRN) individual and unit equipment for 176th Engineer Brigade (TXARNG): preventive maintenance checks and services (PMCS), organizational maintenance, maintenance records, preservation storage conditions, fault reporting, deadlining, and evacuation or shop support IAW applicable TMs, TBs, MACs, and cited Army publications. Unit commanders publish unit procedures that describe how their formations execute those maintenance requirements.

2. APPLICABILITY

This SOP applies to all battalions, companies, detachments, staff sections, and personnel assigned or attached to 176th Engineer Brigade (TXARNG) who perform or supervise maintenance on unit CBRN equipment listed in unit authorization documents and supported by applicable TMs, and unit personnel who process supply actions supporting paragraph 4.5.

• Maintain maintenance schedules and records IAW DA Pam 750-8 and unit business rules
• Coordinate fault verification, deadline tagging, work orders, and evacuation IAW unit procedures
• Submit all assigned CBRN test, measurement, and diagnostic equipment and other maintenance-related equipment requiring calibration through established calibration channels IAW AR 750-43 and unit TMDE procedures
• Identify supplies needed for TM-directed PMCS and organizational maintenance and submit requisitions or materiel requests for those items through unit supply IAW AR 710-2 and unit supply procedures

4.4 Maintainer and operator executors

Personnel authorized by TM and commander orders to execute operator or organizational maintenance will:

• Perform PMCS and authorized maintenance tasks exactly IAW TM, TB, SOUM, and MAC
• Document faults, services, and deadlines IAW DA Pam 750-8 and GCSS-Army when that system is authoritative
• Report faults outside authorized maintenance level through the CBRN Primary or supervisor designated in orders
