It also applies to handwritten observations or remarks which are made in data packages or worksheets. 2.0 Summary of Procedure: The procedure is a general list of rules to be used for data reporting. This includes use of ink, white out, significant figures and rounding. Proper noting of observations and remark ence or reporting is also described. 3.0 Safety: N/A iffnillld k coo : i 4.0 Equipment and Materials: cc: 1 Ink pen 'Ai s e Red Sumo ,w , 5.0 Procedure: 5.1 The only writing instrument approved for documentation is an ink pen.
