Safety Devices parts diagram: 1 pressure relief valve, 2 high-temperature shutdown, 3 low-level shutdown, 4 thermowell, 5 relay, 6 wire bundle. 8 parts in 6 top-level items. — Safety Devices parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Pressure Relief Valve	1×	ASME-stamped relief valve set at vessel MAWP, discharging to a safe location.
2	High-Temperature Shutdown	1×	Hard-wired switch that closes the fuel train if bath temperature runs away.
3	Low-Level Shutdown	1×	Protects exposed fire tube
4	Thermowell	2×	Closed-end well letting temperature elements be changed without opening the vessel.
5	Relay	2×	Electromechanical switch in which a small coil current closes or opens contacts rated for a much larger load, isolating control circuits from what they switch.
6	Wire Bundle	1×	Group of insulated conductors cut to length, terminated, and bound together to carry power and signals between the assemblies of a machine.
