					 hatch opening, deck opening, or companionway opening through which access must
					 be had, and whose open area is less than 18 square feet, shall be guarded by a
					 guardrail which will not have to be removed to give access to or through the
					 opening. Where such railings are located on tank tops or inner bottoms, they
					 shall not be less than 30 inches or more than 31 inches high, shall completely
					 encircle the opening, and shall consist of a single rail. Rail and uprights
					 shall be of iron or steel.

Where ladders extend through the opening, necessary gaps
						shall be left in the railings.

					 protection.
