3.1 Every commercial parasail operator shall have a hard mount or handheld visual weather monitoring device. VHF alone is not acceptable.3.2 Each vessel Master shall maintain a weather log in accordance with the procedures in Section 4.3.3 Wind Conditions:3.3.1 Commercial parasailing is prohibited when the current observed wind conditions in the area of operation include a sustained wind speed of more than 20 mph, wind gusts of a difference of 15 mph greater than the sustained wind speed, the wind speed during gusts exceed 25 mph or rain or heavy fog results in reduced visibility of less than 0.5 mile, or when a known lightning storm comes within 7 miles of the parasailing area.3.3.2 Hawaiian Islands region: due to the consistent nature of the offshore trade winds, operators in this region may operate under a 5 mph allowance to the sustained wind speed for offshore wind conditions only. Onshore wind conditions remain the same in accordance with 3.3.1. Therefore, commercial parasailing may occur in sustained offshore wind speeds up to 25 mph.3.4 Sea Conditions—It is understood that sea conditions can cause additional loading of the parasail tow line.3.4.1 Operators in lakes, intercoastal areas, and rivers shall not operate in sea conditions or a wave height that exceed 3 ft. Attention should be given to the specific body of water in these cases as these locations are typically protected areas. Therefore a wave height or water surface condition that meets or exceeds 3-ft waves or chop may be produced by wind that exceeds the 20 mph threshold described in 3.3.3.4.2 Operators in offshore areas shall not operate in sea conditions that exceed a wave height of 4 ft, unless wave height and period are in accordance with the following calculation: 3 s of period for every 1 ft of wave height (for example, 4 ft = 12 s, 5 ft = 15 s, etc.). Wind speed and payload shall also be taken into consideration at all times of operation. The best evidence of wind and wave conditions within the flying area shall be determined by the vessel Master and may differ from a weather service report.3.5 In no case shall parasail operations be conducted in weather conditions that exceed the manufacturer's specified limitations of the equipment being used.1.1 This guide covers monitoring weather conditions for safer parasail operation.1.2 This guide details parasail operators having weather-monitoring devices and keeping a weather log on board their vessels.1.3 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5.1 This practice is provided to develop and maintain uniformity in practices for use, selection, location, placement, and content of labels on treestands and climbing sticks, particularly with regard to quality assurance and safety.5.2 It is emphasized that the use of these practices will not alter the validity of data determined with specific tests, but provides guidance in the interpretation of test results (valid or invalid) and guidance in the selection of a reasonable general provision in those instances where no standard exists today.1.1 This practice provides guidance for providing user labels on treestands.1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

5.1 This practice is provided to develop and maintain uniformity for the evaluation of the load capacity of ladder and tripod type stands and climbing sticks, particularly with regard to quality assurance and safety factors.5.2 It is emphasized that the use of these procedures will not alter the validity of data determined with specific test methods, but provides guidance in the interpretation of test results (valid or invalid) and guidance in the selection of a reasonable test procedure in those instances where no standard exists today.1.1 This practice provides guidance for testing the load capacity of ladder and tripod type treestands. This practice also applies to climbing sticks which shall meet the same requirements as the steps to ladder and tripod type stands. For changes to this specification since the last issue, refer to the Summary of Changes section at the end of the standard.1.2 The values stated are in inch-pound units and are to be regarded as the standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This specification covers the physical and dimensional requirements and associated test methods for corrugated polyethylene (PE) pipe and fittings intended for underground applications, particularly in soil drainage and septic field leach beds, where soil support is given to the flexible walls. Pipe and fittings shall adhere to physical test requirements such as elongation, brittleness, pipe stiffness, and perforations.1.1 This specification covers requirements and test methods for materials, marking dimensions, workmanship, elongation, brittleness, pipe stiffness, and perforations for corrugated polyethylene (PE) pipe and fittings in nominal sizes of 3 to 6 in., inclusive.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard..Note 1—Along with sizes 3 to 6 in. covered in this specification, sizes 4 to 24 in. are described in Specification F667.1.3 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.1.4 The following precautionary caveat pertains only to the test methods portion, Section 8, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
