GENERAL PROVISIONS
§ 29.161. Definitions.
The following words and terms, when used in this subchapter, have the following meanings, unless the context clearly indicates otherwise:
Engine—Any machine which converts air, gas, oil, steam or water into mechanical power, including belt or gear-driven reciprocating compressors, pumps and blowers.
Guarded, encased or enclosed—The object is so covered, fenced or surrounded that contact, which may result in injury, at the point of danger is remote.
Hazardous—The location of an object so accessible that it permits contact which may result in injury.§ 29.162. Scope.
This subchapter sets forth rules to safeguard the lives, limbs and health of workers in industries in which stationary engines are used, and places the responsibility for complying with these rules upon the employer and employe.
§ 29.163. Penalty.
Any person who violates any of the provisions of this subchapter and any regulations of the Department or who interferes with the Department or its duly authorized representative in the enforcement of this subchapter or regulations shall be penalized under the provisions of section 15 of act of May 18, 1937 (P. L. 654, No. 174) (43 P. S. § 25-15).
OPERATION
§ 29.171. All installations.
(a) Starting signal. When an engine is connected directly with the line shafting or remote machinery, notice shall be given by an effective alarm or signal before the engine is started.
(b) Engine. A safe method shall be provided for turning over the engine by hand.
(c) Valves. Fixed ladders or stairs shall be provided for access to such emergency throttle or stop valves that are not operated from the floor or other accessible places.
(d) Platforms. Platforms and walks on engines shall have railings and toeboards as specified in Chapter 47, Subchapter G (relating to railings, toeboards, open-sided floors, platforms and runways). This requirement applies also to the engine bed alongside the connecting rod or crosshead when it is used as a foot walk.
(e) Lubrication. The engine bearings, journals, eccentrics, crank pins and the like, shall be oiled from outside the guardrailing.
§ 29.172. New installations.
Steam traps used to discharge water from steam separators shall be so installed that their operation is evident.
DESIGN
§ 29.181. All installations.
(a) Guarding. Engines shall have all exposed wheels, pulleys, gears, clutches, couplings, collars, belts, shafting, keys and set screws guarded as specified in Subchapter C (relating to mechanical power transmission apparatus).
(b) Safety valves. Receivers between high presure and intermediate and low pressure cylinders shall be protected by one or more safety valves of sufficient capacity adjusted to release at the maximum safe working pressure of such receivers. Relieving capacity of the safety valve shall be not less than the capacity of the live steam connection to such receivers.
(c) Pressure gauges. Receivers shall be provided with pressure gauges.
(d) Separators. Effective separators or ample drains shall be provided in the main steam line above the throttle.
(e) Vacuum breaker. The jet condenser shall be provided with an automatic vacuum breaker to prevent water from entering the engine cylinders.
(f) Speed limit. Engines of 300 horsepower or more shall be equipped with an approved automatic independent, speed limit device. This requirement does not apply to a reversing engine connected by shafting, couplings, or gears to a constant load.
(g) Governor. Each engine shall be equipped with an effective governor, which at all times automatically controls the speed of the engine, except when the load itself acts as an effective governor. Fly-ball governors shall be equipped with an automatic stop to shut off the supply of steam in the event of derangement of the governor.
(h) Valve gears and belt stop. Valve gears of engines not controlled by fly-ball governors shall be so arranged, or other provisions made, that when the load is removed, the engine stops if the governor fails to function. A broken belt stop is considered sufficient for slide or four valve engines.
REPAIR
§ 29.191. All installations.
(a) Blocking. Positive means shall be provided for blocking and holding immovable vertical and large horizontal engines during adjustments and repairs.
(b) Examination static. A complete static examination of all engines shall be made at least once every three years and a complete record kept of conditions found, with full information relative to defective parts and of repairs made on the engines.
