West Virginia Code of State Rules › Agency 56 - Miners' Health, Safety And Training › Title 56 - LEGISLATIVE RULE OFFICE OF MINERS' HEALTH, SAFETY AND TRAINING › Series 56-04 - Rules Governing Protective Clothing And Equipment › Section 56-4-6 - Self-Contained Self-Rescue Device Storage Cache Plan

Current through Register Vol. XLI, No. 28, July 12, 2024
6.1. Within 30 calendar days of the effective
				date of this rule, all operators of all mines shall submit an SCSR Storage
				Cache Plan for approval by the Director in accordance with W. Va. Code
				§22A-1-36. The design,
				development, submission, and implementation of the SCSR Storage Cache Plan
				shall be the responsibility of the operator of each mine.
6.2. Operators shall revise all approved SCSR
				storage cache plans and submit those to the Director no later than 60 days
				after any amendments to this rule become final.
6.3. Within 30 calendar days after submission
				of the SCSR Storage Cache Plan, the Director shall either approve the plan as
				submitted, or shall reject and return the plan to the operator for modification
				and resubmission, stating in detail the reason(s) for such rejection. If the
				plan is rejected, the Director shall give the operator a reasonable length of
				time, not to exceed 15 calendar days, to modify and resubmit such
				plan.
6.4. In developing the SCSR
				Storage Cache Plan, the operator shall take into consideration the following:
				the need for SCSRs in the accidents described in W. Va. Code
				§22A-2-66; the number of employees
				of the particular mine; the location of the particular mine; the physical
				features of the particular mine; and any other aspect of the particular mine
				the operator deems relevant to the development of the SCSR Storage Cache
				Plan.
6.5. Each SCSR Storage Cache
				shall be housed in a container constructed to protect the SCSRs from normal
				operational damage; be made of a material that is non-combustible; shall be
				easy to open during an emergency escape; be noted on the escape-way map
				required by W. Va. Code §22A-2-1; and
				included in the mine rescue plan required pursuant to W. Va. Code
				§22A-1-35(q).
6.6. One SCSR storage cache shall be placed
				at a readily available location within 500 feet of the nearest working face in
				each working section of the mine and each active construction or rehabilitation
				site. Distances greater than 500 feet, but not to exceed 1,000 feet, are
				permitted upon approval of the Director. However, where miners are provided
				with personal SCSRs that are MSHA rated for less than 60 minutes, travel to
				these storage caches shall not exceed 5 minutes as determined by the
				height/travel time table as specified in W. Va. Code R.
				§56-4-6.9.2.
6.7. Each of the
				storage caches specified in Section 6.6 shall contain 2 SCSRs that will provide
				at least 60 minutes of MSHA rated duration per unit for each miner. When each
				miner carries an SCSR that is MSHA rated for less than 60 minutes, the storage
				cache shall hold devices equivalent to 3 60-minute MSHA rated SCSRs for each
				miner. The total number of SCSRs in a stationary storage cache location will be
				based on the total number of miners reasonably likely to be in that area.
				During crew changes involving a mantrip at a working section or an active
				construction or rehabilitation site, a number of mantrip cached 60 minute or
				greater MSHA rated SCSRs equal to the total number of miners reasonably likely
				on the mantrip shall satisfy the total number of SCSRs required for such
				personnel.
6.8. Operators shall
				ensure that storage caches required in Section 6.6 contain: an escape kit
				containing a hammer; a tagline; a supply of chemical light sticks; and an
				escape-way map required by W. Va. Code §22A-2-1.
6.9. Additional storage caches of 60 minute
				or longer MSHA rated SCSRs shall also be placed in readily available locations
				throughout the remainder of the mine as follows:
6.9.1. Beginning at the storage cache located
				at the working section or active construction or rehabilitation site and
				beltlines, pumping and bleeder areas, and continuing to the surface or nearest
				escape facility leading to the surface pursuant to W. Va. Code
				§22A-2-60, the operator shall
				station additional storage caches of 60 minute or longer MSHA rated SCSRs
				containing a number of additional SCSRs equal to or exceeding one each for the
				total number of miners reasonably likely to be in that area at calculated
				intervals that a miner may traverse in no more than 30 minutes traveling at a
				normal pace, taking into consideration the height of the coal seam and
				utilizing the travel times as specified in W. Va. Code R. §56-4-6.9.2. If
				an SCSR has an MSHA approved duration greater than 60 minutes, the intervals
				between storage caches shall be calculated at the distance traveled in 1/2 the
				approved duration.
6.9.2. Said
				intervals shall be calculated in accordance with the following:
