Alabama Code Title 25. Industrial Relations and Labor § 25-9-250

(a) In dangerously dusty locations, electric motors, switches, and controls shall be of dust-tight construction or enclosed with reasonably dust-tight housing or enclosures. Open-type motors, switches, or controls now in use in tipples and cleaning plants in dusty locations may be continued in use until such dust-tight equipment can be procured or until they can be corrected with reasonably dust-tight housing or enclosures.

(b) Structures shall be kept free of excessive coal dust accumulations.

(c) Where coal is dumped at or near air intake openings, reasonable provisions shall be made to prevent the dust from entering the mine.

(d) Where repairs are being made to the plant, proper scaffolding and proper overhead protection shall be provided for workmen wherever necessary.

(e) Welding shall not be done in dusty atmosphere or dusty locations, and firefighting apparatus shall be readily available during welding.

(a) Before solicitation. Information concerning proposed acquisitions shall not be released outside the Government before solicitation except for presolicitation notices in accordance with 14.205 or 36.213–2, or long-range acquisition estimates in accordance with 5.404, or synopses in accordance with 5.201. Within the Government, such information shall be restricted to those having a legitimate interest. Releases of information shall be made (1) to all prospective bidders, and (2) as nearly as possible at the same time, so that one prospective bidder shall not be given unfair advantage over another. See 3.104 regarding requirements for proprietary and source selection information including access to and disclosure thereof.

(b) After solicitation. Discussions with prospective bidders regarding a solicitation shall be conducted and technical or other information shall be transmitted only by the contracting officer or superiors having contractual authority or by others specifically authorized. Such personnel shall not furnish any information to a prospective bidder that alone or together with other information may afford an advantage over others. However, general information that would not be prejudicial to other prospective bidders may be furnished upon request;  e.g., explanation of a particular contract clause or a particular condition of the schedule in the invitation for bids, and more specific information or clarifications may be furnished by amending the solicitation (see 14.208).
