46 C.F.R. § 62.35-50 Tabulated monitoring and safety control requirements for specific systems.
Title 46 - Shipping
The minimum instrumentation, alarms, and safety controls required for specific types of systems are listed in Table 62.35–50.
Notes on Table 62.35–50: 1. The monitoring and controls listed in this table are applicable if the system listed is provided or required. References to ABS Table 41.1 apply to the “Operation,” “Display,” “Alarm,” and “Notes” 1 through 12, except the reference to ACCU in Note 11. 2. Safety limit controls must be provided in navigating bridge primary propulsion control systems. See §62.35–5(c). 3. Safety trip controls and alarms must be provided for all main boilers, regardless of mode of operation. See §62.35–20(a). 4. Loss of forced lubrication safety trip controls must be provided, as applicable. 5. Override of overspeed and loss of forced lubrication pressure safety trip controls must not be provided. See §62.35–5(e)(2). 6. Transfer interlocks must be provided. 7. Semiconductor controlled rectifiers must have current limit controls. 8. Interlocks must be provided. See §62.25–5(a). 9. See subparts 113.10, 161.002, and fire protection requirements of the applicable subchapters. The use of thermal detectors alone is subject to special consideration by the Commandant (G-MSE). Flame detectors may only be used in conjunction with smoke or heat detectors. 10. See §62.50–20(b)(1). 11. Alarms and controls must be failsafe. See §62.30–1. 12. Vital auxiliary boilers only. Also see part 63. [CGD 81–030, 53 FR 17838, May 18, 1988; 53 FR 19090, May 26, 1988, as amended by USCG–2000–7790, 65 FR 58461, Sept. 29, 2000]
