Current through Register 2024 Notice Reg. No. 28, July 12, 2024
This appendix specifies the procedures for analyzing air
						samples for respirable crystalline silica, as well as the quality control
						procedures that employers must ensure that laboratories use when performing an
						analysis required under Section
						1532.3 (d)(2)(E).
						Employers must ensure that such a laboratory:
1. Evaluates all samples using the procedures specified
						in one of the following analytical methods: OSHA ID-142; NMAM 7500; NMAM 7602;
						NMAM 7603; MSHA P-2; or MSHA P-7;
2. Is accredited to ANS/ISO/IEC Standard 17025:2005 with
						respect to crystalline silica analyses by a body that is compliant with ISO/IEC
						Standard 17011:2004 for implementation of quality assessment programs;
3. Uses the most current National Institute of Standards
						and Technology (NIST) or NIST traceable standards for instrument calibration or
						instrument calibration verification;
4. Implements an internal quality control (QC) program
						that evaluates analytical uncertainty and provides employers with estimates of
						sampling and analytical error;
5. Characterizes the sample material by identifying
						polymorphs of respirable crystalline silica present, identifies the presence of
						any interfering compounds that might affect the analysis, and makes any
						corrections necessary in order to obtain accurate sample analysis; and
6. Analyzes quantitatively for crystalline silica only
						after confirming that the sample matrix is free of uncorrectable analytical
						interferences, corrects for analytical interferences, and uses a method that
						meets the following performance specifications:
6.1
Each day that samples are analyzed,
						performs instrument calibration checks with standards that bracket the sample
						concentrations;
6.2
Uses five or more calibration
						standard levels to prepare calibration curves and ensures that standards are
						distributed through the calibration range in a manner that accurately reflects
						the underlying calibration curve; and
6.3
Optimizes methods and instruments to
						obtain a quantitative limit of detection that represents a value no higher than
						25 percent of the PEL based on sample air volume.

(a) Private Roadways and Off-Highway
					 Conditions.
(1) Single-lane private roads
					 with two-way traffic shall be provided with turnouts. Where turnouts are not
					 practicable, a control system shall be provided to prevent vehicles from
					 meeting on such single-lane roads.
(2) On private roads used for two-way
					 traffic, arrangements shall be such that vehicles travel on the right side as
					 much as possible. Signs shall be posted to clearly indicate variations from
					 this system. Where practicable, separate haulage roads shall be provided
					 between loaded and empty units. Haulage roads shall be wide enough to allow for
					 safe passage. Safe distances between moving units shall be maintained.
NOTE: Left hand traffic patterns are permitted provided
						that vehicle operators are advised of the pattern and job site conditions
						warrant that the procedure is safe.
(3) Private roads shall be maintained free
					 from holes and ruts that affect the safe control of the vehicle. Every
					 emergency access ramp and berm used by an employer shall be constructed to
					 restrain and control runaway vehicles.
(4) Where a hazard exists to employees
					 because of traffic or haulage conditions, a system of traffic controls shall be
					 required so as to abate the hazard. (See Section
					 1598(b)).
NOTE: Nothing in this subsection shall preclude the use
						of additional signs that are not included in the Manual referenced in Section
						1598(b). Examples:
						"Haul Road," "Left Hand Pattern," "Scraper Crossing," etc.
(5) Employees (on foot), such as

					 The warning sound shall be of such magnitude that it will normally be audible
					 from a distance of 200 feet and will sound immediately on backing. In congested
					 areas or areas with high ambient noise which obscures the audible alarm, a
					 signaler, in clear view of the operator, shall direct the backing
					 operation.
(b) Those vehicles not
					 subject to 1592(a) and operating in areas where their backward movement would
					 constitute a hazard to employees working in the area on foot, and where the
					 operator's vision is obstructed to the rear of the vehicle shall be equipped
					 with an effective device or method to safeguard employees such as:
(1) An automatic back-up audible alarm which
					 would sound immediately on backing, or
(2) An automatic braking device at the rear
					 of the vehicle that will apply the service brake immediately on contact with
					 any obstruction to the rear, or
(3)
					 In lieu of 1 or 2 above, administrative controls shall be established such as:
(A) A spotter or flagger in clear view of the
					 operator who shall direct the backing operation, or
(B) Other procedures which will require the
					 operator to dismount and circle the vehicle immediately prior to starting a
					 back-up operation, or
(C)
					 Prohibiting all foot traffic in the work area.
(4) Other means shall be provided that will
					 furnish safety equivalent to the foregoing for personnel working in the
					 area.
