DISTRICT MINE INSPECTOR SHALL PROCEED TO THE SCENE OF
THE ACCIDENT AND DIRECT THE RESCUE, RELIEF, AND
RESTORATION WORK. HE MAY REQUEST THE DIRECTOR OF THE
BUREAU TO COME OR DETAIL ADDITIONAL DISTRICT MINE
INSPECTORS TO ASSIST IF NECESSARY.

REVISOR'S NOTE: This subsection presently appears
as Article 66C, section 647 of the Code.
The only changes made are in style.

7-451. CAP LAMPS.—EVERY WORKER AND OTHER PERSON
UNDERGROUND SHALL USE ONLY APPROVED ELECTRIC CAP LAMPS
FOR PORTABLE ILLUMINATION.

REVISOR'S NOTE: This section presently appears as
Article 66C, section 617 of the Code. The
final two sentences of this section are
proposed for deletion because all mines now
have had sufficient time to secure and
utilize permissible electric cap lamps.
The only other changes made are in style.

7-452. ARCS, SPARKS, AND FLAMES.

BECAUSE OF THE DANGER OF EXPLOSION AND FIRE
HAZARDS, EVERY PERSON IN ANY UNDERGROUND WORKING OF A
MINE IS PROHIBITED FROM INTENTIONALLY CREATING ANY
ARC, SPARK, OR OPEN FLAME, OTHER THAN THOSE WHICH
CANNOT BE AVOIDED IN THE NORMAL PERFORMANCE OF WORK.

REVISOR'S NOTE: This section presently appears as
Article 66C, section 618 of the Code. The
final sentence is proposed for deletion
because it appears as section 7—454. The
only other changes made are in style.

7-453. WELDING AND CUTTING.

WELDING AND CUTTING WITH ELECTRICITY OR FLAME
GENERALLY SHALL BE RESTRICTED TO PLACES WHERE A
TROLLEY LOCOMOTIVE IS PERMITTED. WHERE NECESSARY TO
WELD AND CUT IN FACE REGIONS, THE WORK SHALL BE UNDER
THE DIRECT SUPERVISION OF A CERTIFIED OFFICIAL WHO
SHALL TEST FOR GAS BEFORE STARTING OPERATIONS AND
FREQUENTLY THEREAFTER. IN EVERY WELDING AND CUTTING
OPERATION, PRECAUTION SHALL BE TAKEN AGAINST STARTING
A FIRE, AND THE AREA IN WHICH THE OPERATION TAKES
PLACE SHALL BE ROCK-DUSTED.
