PART 1917—MARINE TERMINALS
§ 1917.156   Fuel handling and storage.
(a) Liquid fuel. (1) Only designated persons shall conduct fueling operations.
(2) In case of spillage, filler caps shall be replaced and spillage disposed of before engines are started.
(3) Engines shall be stopped and operators shall not be on the equipment during refueling operations.
(4) Smoking and open flames shall be prohibited in areas used for fueling, fuel storage or enclosed storage of equipment containing fuel.
(5) Equipment shall be refueled only at designated locations.
(6) Liquid fuels not handled by pump shall be handled and transported only in portable containers or equivalent means designed for that purpose. Portable containers shall be metal, have tight closures with screw or spring covers and shall be equipped with spouts or other means to allow pouring without spilling. Leaking containers shall not be used.
(7) Flammable liquids may be dispensed in the open from a tank or from other vehicles equipped for delivering fuel to another vehicle only if:
(i) Dispensing hoses do not exceed 50 feet (15.24 m) in length; and
(ii) Any powered dispensing nozzles used are of the automatic-closing type.
(8) Liquid fuel dispensing devices shall be provided with an easily accessible and clearly identified shut-off device, such as a switch or circuit breaker, to shut off the power in an emergency.
(9) Liquid fuel dispensing devices, such as pumps, shall be mounted either on a concrete island or be otherwise protected against collision damage.
(b) Liquefied gas fuels —(1) Fueling locations. (i) Liquefied gas powered equipment shall be fueled only at designated locations.
(ii) Equipment with permanently mounted fuel containers shall be charged outdoors.
(iii) Equipment shall not be fueled or stored near underground entrances, elevator shafts or other places where gas or fumes might accumulate.
(2) Fuel containers. (i) When removable fuel containers are used, the escape of fuel when containers are exchanged shall be minimized by:
(A) Automatic quick-closing couplings (closing in both directions when uncoupled) in fuel lines; or
(B) Closing fuel container valves and allowing engines to run until residual fuel is exhausted.
(ii) Pressure-relief valve openings shall be in continuous contact with the vapor space (top) of the cylinder.
(iii) Fuel containers shall be secured to prevent their being jarred loose, slipping or rotating.
(iv) Containers shall be located to prevent damage to the container. If located within a compartment, that compartment shall be vented. Containers near the engine or exhaust system shall be shielded against direct heat radiation.
(v) Container installation shall provide the container with at least the vehicle's road clearance under maximum spring deflection, which shall be to the bottom of the container or to the lowest fitting on the container or housing, whichever is lower.
(vi) Valves and connections shall be protected from contact damage. Permanent protection shall be provided for fittings on removable containers.
(vii) Defective containers shall be removed from service.
(3) Fueling operations. (i) To the extent applicable, fueling operations for liquefied gas fuels shall also comply with paragraph (a) of this section.
(ii) Using matches or flames to check for leaks is prohibited.
(iii) Containers shall be examined before recharging and again before reuse for the following:
(A) Dents, scrapes and gouges of pressure vessels;
(B) Damage to valves and liquid level gauges;
(C) Debris in relief valves;
(D) Leakage at valves or connections; and
(E) Deterioration or loss of flexible seals in filling or servicing connections.
(4) Fuel storage. (i) Stored fuel containers shall be located to minimize exposure to excessive temperatures and physical damage.
(ii) Containers shall not be stored near exits, stairways or areas normally used or intended for egress.
(iii) Outlet valves of containers in storage or transport shall be closed. Relief valves shall connect with vapor spaces.
(5) Vehicle storage and servicing. (i) Liquefied gas fueled vehicles may be stored or serviced inside garages or shops only if there are no fuel system leaks.
(ii) Liquefied gas fueled vehicles under repair shall have container shut-off valves closed unless engine operation is necessary for repairs.
(iii) Liquefied gas fueled vehicles shall not be parked near open flames, sources of ignition or unventilated open pits.
§ 1917.157   Battery charging and changing.
(a) Only designated persons shall change or charge batteries.
(b) Battery charging and changing shall be performed only in areas designated by the employer.
(c) Smoking and other ignition sources are prohibited in charging areas.
(d) Filler caps shall be in place when batteries are being moved.
(e) Parking brakes shall be applied before batteries are charged or changed.
(f) When a jumper battery is connected to a battery in a vehicle, the ground lead shall connect to ground away from the vehicle's battery. Ignition, lights and accessories on the vehicle shall be turned off before connections are made.
(g) Batteries shall be free of corrosion buildup and cap vent holes shall be open.
(h) Adequate ventilation shall be provided during charging.
(i) Facilities for flushing the eyes, body and work area with water shall be provided wherever electrolyte is handled, except that this requirement does not apply when employees are only checking battery electrolyte levels or adding water.
(j) Carboy tilters or siphons shall be used to handle electrolyte in large containers.
(k) Battery handling equipment which could contact battery terminals or cell connectors shall be insulated or otherwise protected.
(l) Metallic objects shall not be placed on uncovered batteries.
(m) When batteries are being charged, the vent caps shall be in place.
(n) Chargers shall be turned off when leads are being connected or disconnected.
(o) Installed batteries shall be secured to avoid physical or electrical contact with compartment walls or components.
§ 1917.158   Prohibited operations.
(a) Spray painting and abrasive blasting operations shall not be conducted in the vicinity of cargo handling operations.
(b) Welding and burning operations shall not be conducted in the vicinity of cargo handling operations unless such hot work is part of the cargo operation.
